Assuming it is referring to the kernel module and not some separate X Windows driver, it might help to load one of synaptics_usb or synaptics_i2c, maybe before X starts? The usual place to put kernel modules to be loaded for no apparent reason is /etc/modules.

Sure it allows creating DNS loops and other weird stuff, but it can also be useful (like a lot of things that can make loops). It is possible with a sophisticated DNS service like Amazon Route53 to resolve the equivalent sort of logic internally and spit out an A record in response to the first request, and still allow geo or other load balancing. At my work we use Route53, and it lets us also chain CNAMEs if we choose. The benefit of that I think is it makes it easier for the client to see how the logic is working. I can see both sides here, but why should this be a rule? -Nick ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

It has a metric called "bytes in flight" which counts unack'd bytes, and I graphed it like this in comparison to window size: http://postimg.org/image/az0hspgkp/ and the spikes clearly match up with retransmissions which makes sense because retransmissions should continue until those segments are acked.

[vox-tech] tcp tuning with wireshark?
I need to increase throughput for long lived tcp connections over ipsec over wan between Amazon in Ireland and a Level3 gigabit link in Ashburn Virginia (currently running at about 20Mbps). I've read various articles saying to enlarge the buffers and make various other kernel tweaks. Some say to base it on the bandwidth delay product, some say just on the link speed, and some say don't bother linux does all that automatically now. Alot of it seems random. However, with wireshark I see that the "bytes in flight" measurement which counts unacknowledged bytes from the source never gets close to the window size sent by the destination. Does this suggest anything in particular to tweak? I got some books on wireshark, which were quite helpful in how to use the graphs and filters, but on tcp performance they mostly just talked about the effect of packet loss. I'm not certain, but I don't think packet loss is the main thing holding back my performance, because there is some which causes a brief dip in the window size and then it recovers. Throughput stays pretty flat. It would be really amazing if there was a flowchart on doing this for linux that could be informed by wireshark io graphs and other graphs. Has anybody ever seen such a chart? If this approach is succesful for me, and I can understand how to do it in several scenarios, I think I will even like to make such a flow chart if it doesn't already exist. Thanks for any tips and disabusement of my misunderstandings about tcp in linux :) Nick ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

I wrote a script a while ago for this sort of situation, which
assumes certain things about the VMs /etc/fstab and
/boot/grub/menu.lst files, then it mounts the lvm partition
filesystems in the dom0 appropriately and you could run rsync
across all of them together:
#!/bin/bash
export DISK=$1
export MOUNTPOINT=$2
ROOTPART=1
/sbin/kpartx -av $DISK
mount "$DISK"1 $MOUNTPOINT
if [ -L $MOUNTPOINT/boot ]; then
ROOTPART=`cat $MOUNTPOINT/boot/grub/menu.lst | perl -nle 'if ($_ =~
/^[\s]kernel.+root=\/dev\/\p{L}+([\d])/) { print "$1"; exit}'`
umount $MOUNTPOINT
mount "$DISK""$ROOTPART" $MOUNTPOINT
fi
cat $MOUNTPOINT/etc/fstab | perl -nle 'if ($_ =~
/^\/dev\/\p{L}+([\d])[\s]+((\/\p{L}+)+)/ ) { $device=$ENV{DISK} . $1 ;
$mountpoint=$ENV{MOUNTPOINT} . $2 ; system "mount $device $mountpoint"}'
mixing bash and perl is a little ugly, and I don't even know if
this was ever actually used for the intended purpose because it
was for somebody else, but I hope it might help you! :)

Can you save the spreadsheet as a csv or tab separated file or
such, then use perl or awk or such to output
addressa, addressb, addressc or
A B , C D ?
Can that sort of format be pasted into yahoo?
Maybe this will work
awk -F , {'printf("\"%s %s\" <%s>, ", $1, $2, $3);'}
If the first column is first name, second column is last name,
and third column is email address.

Although I don't have direct experience with it in China, ssh tunneling has been quite successful for me in the past. The idea is the ssh client running on the computer in China is the proxy server, probably listening to localhost. Firefox or another browser is configured to use the proxy server (the foxyproxy extension helps with it in firefox) and the all of the firefox http, https and dns traffic goes through the proxy, over the ssh tunnel and eventually appears to be coming from the ssh server (outside of China). The only thing to stop this from working, is if the firewall blocks ssh traffic. If you use Squid instead, there will still be normal appearing web traffic, possibly on an alternate port, to a certain host (the proxy server) outside China that isn't blocked. The real destinations will then see the traffic as coming from that one host outside China. Squid also doesn't help to proxy the dns traffic like the ssh tunnel does. The ssh method is so much simpler, more secure and useful (for just shell sessions too, besides the proxy traffic) that I definitely recommend it. This article for example: http://www.extremetech.com/computing/93106-escaping-the-firewall-with-an-ssh-tunnel-socks-proxy-and-putty/ seems to be a good description of how to set it up with the PuTTY ssh client and firefox in Windows. On the ssh server, the default settings should allow the proxying and there is no configuration needed beyond the normal account setup. I hope this helps :) Nick Schmalenberger ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

This makes me think that a small connection is working but not for more data, and maybe path mtu discovery and/or tcp maximum segment size negotiation are broken because pppoe has an mtu of 1492 instead of the ethernet mtu of 1500. It might be wrong, but I think being able to get response headers from the server over telnet from outside would be the next progress to make in troubleshooting it.

The default firmware supports ipv6 and is so labeled on the box, and I bought them for just that reason. I haven't had a chance to use the dir-825 yet, but the dir-615 works great with ipv6 in 6to4 mode and the wireless works great with wpa2 also. Also, check out http://www.wi-fiplanet.com/columns/article.php/3816236/The-DD-WRT-Controversy.htm for information about dd-wrt, the guy who makes dd-wrt seems to think of it more as his private business than an open community project. I've had alot of good experiences with OpenWRT which is definitely an open community, but the default firmwares in various routers I've used have also worked well. I think if you do get a new router, be sure to look for ipv6 support because its definitely a crucial feature these days. With ipv6 I am even able to print files directly from my mail server to my printer at home without having to forward a port on the router, its great! Switching to wpa1 should be fine also.

Apparently ibm compatible bioses can't handle any sector size but 512 bytes, so the firmware will always say its 512 even though its 4096 internally, and you are just expected to make the partitions aligned on a 4096 byte boundary, which seems to be painful and annoying to do in fdisk or parted. Parted also likes to use metric instead of binary prefixes which doesn't help at all. I was trying to install centos 5.4 on the drives when I got them about 6 months ago, and haven't played with them much lately. Maybe parted or fdisk have gotten better since then about setting the alignment?

Different distros and other unixes have different log file names for this, but dmesg is pretty much everywhere. It should say that the usb stick was detected as a storage device and what partitions are on it. Then you can mount the filesystem on the partition, or maybe there are no partitions and the filesystem is just on the whole disk like a floppy. Dmesg should say it was detected though, then you would run something like mount /dev/sdb1 /mnt or maybe mount -t vfat -o uid=yourusername /dev/sdb1 /mnt which would say its a vfat filesystem and make everything owned by you instead of root.

I suppose the talk by Owen DeLong from Hurricane Electric in July will demonstrate this. How I would troubleshoot this, is run tcpdump to see if the traffic is coming in. Then, see if there are any rules in the INPUT chain in iptables that might be blocking it (or in the FORWARD chain in the dom0, and you can run tcpdump on peth0 and the vif interface also to see both sides of the xen bridge/iptables FORWARD chain). But you said it works with the echo server, so I guess the traffic is coming into the domU. If its passing through iptables in the domU, then you could try running netcat on the telnet port with telnet negotiation instead, or telnetd (there are various ones, maybe some have easier troubleshooting?) with debugging turned on and not daemonizing so you can see more output about if it is configured correctly. Anyway, maybe those steps are kind of out of order with regard to how the traffic goes up the network stack but it should be with xen: physical ethernet->iptables FORWARD->dom0 vif-> domU eth0->iptables INPUT->user process network socket I hope that makes sense.

I use this with the foxyproxy firefox extension but the builtin proxy manager works as well for single configurations. If it is allowed on the server, you just run ssh -D 8080 or some other port above 1024 on the client and then the ssh client is a proxy server listening to localhost on that port. Its very easy and secure. Also check out mod_proxy in apache, I haven't used this myself but I think it works with just http. You could also have the ssh server listen to tcp port 443 or 80 if port 22 is blocked in china but not the ssh protocol itself. I have mine listen to 443 and its useful where only 80 and 443 are allowed in a stateless firewall.

Also, if you are booting a raid mirror be sure to install grub on
both drives and confirm they are both bootable without the other
drive. Its easy to forget about this until a disk needs to be
replaced and the server is already shutdown.

In rescue, try to mount the root filesystem, and /boot if it is a
separate filesystem. Then chroot to the mountpoint of the root
filesystem ("chroot /mnt" or something), and do "grub-install
(hd0)" (the grub way of saying the disk) or "grub-install
/dev/sda" or /dev/sda1 or whichever disk/partition is the root
filesystem. I'm not sure if its more appropriate to install grub
on the disk or partition but I don't think it hurts to try both.
While the root filesystem is mounted you can also make any
corrections to the menu.lst if needed.

[vox-tech] ssh host key generation in init script
Hi, I need to be able to generate ssh host keys at boot time instead of installation if they don't exist. CentOS and upstream openssh handle this in the init script with ssh-keygen, but debian calls it from /var/lib/dpkg/info/openssh-server.postinst. I put ls /etc/ssh/ssh_host_* &> /dev/null || /usr/sbin/dpkg-reconfigure openssh-server in a function in /etc/init.d/ssh and it works fine, but ubuntu uses dash instead and it says ls: cannot access /etc/ssh/ssh_host_*: No such file or directory when ls is true. I also tried test -f /etc/ssh/ssh_host_* || /usr/sbin/dpkg-reconfigure openssh-server and it says test: 1: /etc/ssh/ssh_host_dsa_key: unexpected operator when the test is true. Can someone help me make this more portable? Thanks! Nick Schmalenberger ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

I know people who just start unscrewing things without getting a service manual first, but I try not to because there might always be another plastic tab or screw under a sticker I don't see until I break it or something. I think Toshiba and IBM/Lenovo have better service manuals than Dell. The Dells have photo illustrations that I think are harder to understand than the line drawings in the other manuals and the dells are also generally a bunch of html pages instead of a pdf. Some of them may also be only available on the web. At least Dell service manuals are easily available though, I think with the Toshiba I had to email an authorized service center because it wasn't on toshibas site. With Dell and IBM it was right on their website, and with IBM you could download a pdf which was nice. For Thinkpads thinkwiki.org and forum.thinkpads.com are also very helpful sites. Lately though, I've actually gotten more cautious or lazy about repairing laptops because some of those that I repaired or saw repaired just had more problems later. For some problems it may not be worth the trouble if it involves taking out the motherboard or lcd panel. But repairing laptops is definiely possible and often works out pretty well. There are a huge amount of parts available on ebay. There are also tricks you may already know about like using an ice cube tray for screws and putting screws taken out at later steps in "later" compartments. Have fun.

I did dist-upgrade to get the packages that needed to be upgraded then apt-get installing a few of them. That way it was easier to pay close attention to merging and rearranging local changes to the apache config files and such. Upgrading postgresql from 7.4 to 8.1 turned out to be extremely easy because they can both be installed at the same time listening to different ports and the debian tool pg_upgradecluster made the conversion completely painless and took less than 5 minutes. I think the apache upgrade was the most trouble, but that was mostly because I didn't put my local changes in /etc/apache2/conf.d/ which I have done now and upgrades to apache2 wont mess with it.

Some of the cheaper poweredges don't actually have hardware raid, dell is lying. Search for fakeraid and the poweredge model. What is the raid setup? What are the raid devices called in the installer that you made the filesystems on, or did you get that far? If not, the installer probably doesn't support your raid controller, and maybe it is fakeraid. On my poweredge with fakeraid, I just used software raid which the debian installer sets up very neatly.

Otherwise, you could do "update-rc.d -f xdm remove" or whatever your display manager is. That is what would happen if you remove the package, except it is still there and you could still do "/etc/init.d/xdm start" if you felt like it. When you do startx or log in through the display manager, it should try to start your window manager, and (I think, correct me if I am wrong) if you don't have one it gives you a fixed size xterm, which you can really do a decent amount with. I seem to remember having problems a few times getting icewm to start when I start X and I think adding it to .xinitrc was one way to get it to work. The correct debian might have something to do with /etc/alternatives. You could also try purging everything X related then reinstalling xbase-clients which will depend on all the rest and you might get twm or something too.

You should be able to tell by looking at the back of the case. Is the video connector on the motherboard, perpendicular to it in slots, or both? If it is in slots, then you can open the case and look at the card, it should have make and model.

Better burning programs will give you an option to burn from a CD image, which is what a ".iso" file is (ISO9660 from the http://www.iso.org/ actually).

Re: [vox-tech] bad partition table
Some more information about my problem is that hdparm insists that the geometry of this bad disk is 838 cylinders, 240 heads, and 63 sectors per track. In the machine this drive was in when the problem started, the BIOS was set to autodetect all IDE parameters. When I go in the BIOS now and use the tool to automatically detect once parameters of disks and put them in table, so as not to autodetect again every boot, it gives me three options for normal, LBA, and large address modes. Large mode uses the same parameters I said above that "hdparm -g" gives. "hdparm -i" says that there are 13410 cylinders, 15 heads, and 63 sectors per track, and this is also what the drives label says. This is also what the BIOS detects for normal address mode. But if I manually put that into the BIOS, hdparm still says 838 cylinders and so on. All of yesterday, I thought the problem was just with the geometry setting, and by playing around with that, I think I was able to get hdparm to say the right thing but not anymore. When I redid the root partition with fdisk, it was large mode because that was what was autodetected and I figured since it was autodetect before and when the problem started, maybe it should be if I want to fix it too. When I put this drive in one of my other machines, that also happens to have a disk of nearly the same model and exactly the same geometry, the bad disk is, before and after fdisking, autodetected with large address mode. But the other disk is autodetected in normal mode and hdparm reads 13410 cylinders. So somehow this one bad disk doesn't want to be addressed in normal mode or something. The whole geometry issue just confuses me. When I recreated the root partition while the bios had the disk in large address translation mode, did that put "large address translation mode" in wherever "hdparm -g" gets its information from? I wish I could just be in normal mode since apparently linux doesn't need any of the translation modes anyway. Did I just dig my hole deeper by recreating the root partition when the disk was in large address mode? ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

[vox-tech] bad partition table
On Saturday, somehow my partition table got destroyed. Today, I learned about gpart from the very nice Partition-Rescue-HOWTO. Gpart will guess the partition table based on the actual disk structure, so you can give cylinder numbers to recreate the partitions in the right places with fdisk. In this way, I was able to mount my root partition and read files. But I am having trouble restoring the rest, and I can't boot off the disk yet. So does anybody know of some system file that might have my the addresses of my old partitions written in it so I don't have to guess anymore? I use Debian. Thanks.

Huh. Thanks, I didn't know that.

Re: [vox-tech] Installing Java
Jay, If you haven't already gotten the Blackdown thing from where Rick Moen said, you could try getting the RPM of JDK from Sun and converting it to deb with alien, then installing it. It worked nicely for me and I now have v1.5 , although you may prefer the Blackdown one anyway because it is apparently more free and certainly easier to install and maintain with apt. Also, when I used alien on the RPM of just JRE and then installed the plugins, they didn't work, I had to get JDK. So that is another option to consider, especially if you want v1.5 . Alien is useful because a lot of places will only distribute their proprietary distribution format and RPMs. Something else to consider.

I have two systems with SoundBlaster 16 cards and they both work nicely with the ALSA drivers from kernel 2.6 . So maybe Pete Salzman is right about a kernel problem. OSS is deprecated in 2.6 and I guess there is a reason. I like at least how all the ALSA module names start with snd- so you know what they are for. I'm not an expert, but it seems better organized because of things like that, and there are alot more cards supported. Apparently OSS has licensing problems which I guess is why ALSA is more of a complete solution now. ALSA has OSS emulation also, which is useful for things which haven't had much done with them for a while and were written in the age of OSS. Pete Salzman said the other day about Robert Scofield's problem that compiling your own kernels is helpful in learning about the structure of Linux, and I agree with him. I have learned alot from the kernel docs and the help in the config. I also feel more distro independent and more portable.

Re: [vox-tech] uhci memory problem
Thanks. >Just guesting, but probably another device is using that I/O region. >Try >taking out some of the PCI devices and see if that helps. If it >does, try >shuffling the problematic PCI device to another PCI slot -- >it may or may not >help. My system is a laptop, and my usb controller is integrated. The only removable device it has is the network card. I tried removing it, but it didn't help. Anyway, it's io ports are in the 4000s, not the f000s where my usb controller is. I will append my /proc/ioports, but I can't see any overlaps or anything obviously wrong. The range for the usb controller is fca0 to fcbf. Maybe that is too small or something. The ide controller and sound card are below and above. The sound card is also below because it has several ranges. Why does it use so much? What are the regions anyway, in relation to the io port ranges? So, here is my /proc/ioports: -001f : dma1 0020-0021 : pic1 0040-0043 : timer0 0050-0053 : timer1 0060-006f : keyboard 0080-008f : dma page reg 00a0-00a1 : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 02f8-02ff : serial 0376-0376 : ide1 03bc-03be : parport0 03f6-03f6 : ide0 03f8-03ff : serial 04d0-04d1 : pnp 00:0b 0760-0760 : pnp 00:00 07bc-07be : parport0 0cf8-0cff : PCI conf1 1000-103f : :00:02.3 1000-103f : motherboard 1000-1003 : PM1a_EVT_BLK 1008-100b : PM_TMR 100c-100f : GPE0_BLK 1010-1015 : ACPI CPU throttle 1040-105f : :00:02.3 1040-104f : motherboard 1040-104f : pnp 00:0b 1050-105f : motherboard 1050-1051 : PM1a_CNT_BLK 4000-40ff : PCI CardBus #02 4000-40ff : :02:00.0 4000-40ff : 8139too 4400-44ff : PCI CardBus #02 4800-48ff : PCI CardBus #06 4c00-4cff : PCI CardBus #06 f800-f8ff : :00:06.0 fc58-fc5b : :00:07.0 fc58-fc5b : ESS Solo-1 fc5c-fc5f : :00:07.0 fc5c-fc5f : ESS Solo-1 fc60-fc6f : :00:07.0 fc60-fc6f : ESS Solo-1 fc70-fc7f : :00:07.0 fc70-fc7f : ESS Solo-1 fc88-fc8f : :00:06.0 fc90-fc9f : :00:02.1 fc90-fc97 : ide0 fc98-fc9f : ide1 fca0-fcbf : :00:02.2 //my usb controller fca0-fcaf : motherboard fcc0-fcff : :00:07.0 fcc0-fcff : ESS Solo-1 Thanks for any help.

[vox-tech] uhci memory problem

[vox-tech] DMA conflict
list, First, I solved the problem I posted about a few weeks ago wtional aeronautical beacons is being phased out and the frequencies also arhere I was having trouble configuring the sound on my laptop. For some reason, installing udev fixed it. Now I'm having a different problem in a different computer. In this other computer, I have an ISA soundcard. When it works, it uses two DMA numbers, 1 and 5. /proc/dma says: 1: SoundBlaster - 8bit 4: cascade 5: SoundBlaster - 16bit . I guess cascade is shared by the PCI devices. For PCI devices, I have a video card, a NIC, a SCSI controller, the south bridge, and a TV tuner card. The TV card has been causing the most trouble, but there are other problems too. If I use an AGP video card instead of the PCI one, the computer hangs at boot just after the sound card has been initialized. When I have the TV card in, the sound card driver doesn't get loaded. I can modprobe it manually, but it still doesn't work. When I watch TV, it is very unstable and if I try to move the window around or use a control button there will be some video problem like where the window or button was will turn orange or the computer will hang. The bttv driver FAQ indicates that there may be DMA problems: http://linux.bytesex.org/v4l2/faq.html#oops It says to disable DMA for IDE. Is there some better way? The DMA channels are supposed to be shared, right? If I have to disable DMA for IDE how do I do it? In Documentation/ide.txt of the kernel sources, I can see where it says to argue to the kernel for a particular drive to use DMA, but I can't see how to disable DMA. Anyway, DMA exists for a reason I guess, so I'd prefer to make it work if possible. This message indicates that my chipset, VIA MVP3, may have DMA problems: http://www.ussg.iu.edu/hypermail/linux/kernel/0308.1/0375.html . So do I just have a chipset that doesn't work well with DMA or what? Also, the tuner on my card that is autodetected is the wrong one because the channels are offset, so I need to manually argue for a different tuner. There is nothing in /etc/modprobe.d/ about bttv, or my NIC or SCSI controller for that matter. I suppose the NIC module is called when bringing up network interfaces, and the SCSI controller module is called when bringing up drives, but when is bttv called? How do I give arguments to it? Thanks in advance. Nick ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
Re: [vox-tech] alsa configuration
list, My distribution is Debian. I found a page on the ALSA website for my sound chip with some lines to go in my /etc/modules.conf: # ALSA portion alias char-major-116 snd alias snd-card-0 snd-es1938 # module options should go here # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss Apparently with Debian they are supposed to be put into /etc/modutils/file and then the update-modules utility is used to insert them into /etc/modules.conf. I also have two files about sound in /etc/modprobe.d/ , ./alsa-base and ./sound: gwaihir2:/etc/modprobe.d# cat ./alsa-base install snd-pcm /sbin/modprobe --ignore-install snd-pcm && /sbin/modprobe snd-pcm-oss install snd-mixer /sbin/modprobe --ignore-install snd-mixer && /sbin/modprobe snd-mixer-oss install snd-seq /sbin/modprobe --ignore-install snd-seq && /sbin/modprobe snd-seq-oss gwaihir2:/etc/modprobe.d# cat ./sound alias snd-card-0 snd-es1938 alias sound-slot-0 snd-es1938 . When I run alsaconf, it says it has detected my card and is going to rewrite /etc/modprobe.d/sound , but then there is a message on stderr saying: "/usr/sbin/alsactl: save_state:1061: No soundcards found...". I am sort of confused about the differences between /etc/modprobe.d/ and /etc/modutils/ . Are they just different ways that different distros do the same thing and I have some combination of both? I imagine that that could be causing my problem. If so, what is the solution? Thanks. Nick ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
[vox-tech] alsa configuration
list, I have been trying to get the sound to work in my computer. At boot when the ALSA mixer settings would be loaded, it fails and says to manually use "alsactl restore". When I do that, it says "alsactl: load_state:1134: No soundcards found...". When I google on that, peoples problems mostly seem to be conflicts between OSS and ALSA when they have both installed at the same time.

[vox-tech] removal of postgresql
Thanks Kevin for telling me about dpkg -S . When I run it, it lists: " postgresql: /etc/cron.d/postgresql postgresql-client: /etc/postgresql/postgresql.env postgresql: /etc/postgresql/pg_hba.conf postgresql: /etc/init.d/postgresql postgresql-contrib: /etc/logrotate.d/postgresql-contrib postgresql: /etc/logrotate.d/postgresql postgresql: /etc/logcheck/ignore.d.paranoid/postgresql postgresql-client: /usr/share/doc/postgresql-client postgresql: /etc/logcheck/violations.ignore.d/logcheck-postgresql postgresql: /etc/logcheck/ignore.d.server/postgresql postgresql: /etc/logcheck/ignore.d.workstation/postgresql postgresql: /etc/postgresql postgresql: /etc/postgresql/pg_ident.conf ". It used to list a lot more, like docs, but I did apt-get remove on their associated packages. When I did "apt-get remove postgresql-doc" it said it couldn't remove /usr/share/doc/postgresql because it wasn't empty. I don't see why that should be a problem for apt-get, but /usr/share/doc/postgresql and /usr/share/doc/postgresql-client are still there. But now package postgresql-doc seems removed from the dpkg listing. The above listed files are all that dpkg lists matched against "postgresql", so I suppose there could be more in files that don't have "postgresql" in their pathname. I did "apt-get remove" on each of the packages listed above, and apt-get said they were not installed. I tried deleting a few by hand, especially the cron one because it was harassing me, but it is still listed by dpkg. Is the apt-get/dpkg contradiction a real bug? Do you think I should just try installing from source? Thanks. Nick ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
[vox-tech] problem solved!
list, Thanks Kevin. That link you gave me really helped, and now my problem is solved! Before I read that article, I didn't know about make clean. That wasn't my real problem though. My problem was that for some reason, one of my kernel images had been installed in / instead of /boot/ , and that was where lilo was pointed. I don't know how it got that way, but it is fixed now. I am now running kernel version 2.6.8.1 and the module problem I was talking about a few weeks ago is solved too. Thanks! Another problem I'm having is a while ago I tried to install postgresql. I just did "apt-get install postgresql". It installed a whole bunch of stuff, but not the binaries. So, I did "apt-get remove postgresql". Besides giving an error about not being able to remove the binaries that were never installed in the first place, apt-get also didn't remove a cron entry about the postgresql log, which was removed. So now I'm getting a whole bunch of mail from cron about how it wants to do something to this log that doesn't exist anymore. So I deleted the cron entry. Time will tell if this will be effective. However, there is still a whole bunch of other stuff left around, like the whole /usr/lib/postgresql directory. A while ago I tried manually deleting everything but I couldn't find it all. Why didn't apt-get remove it completely? Stuff like this happened to me all the time when I was running Windows. I don't think it is a problem with apt-get specifically but with any opaque utility. With apt-get and with Microsoft Windows you just have to trust it to do the right thing, and a lot of the time, it doesn't. That is a lot of why I switched to Linux. That is also why a few months ago I was asking on this list for help compiling a mess of libraries for X. This list advised me to use the binary package distribution tools that come with my distribution, to trust them. I did, and on balance it was absolutely worth it. Without apt-get I would never have gotten all those libraries to work together. However, apt-get has now failed me with postgresql thing, which I would still like to get working eventually, and firstly I want to clean out its remnants. What should I do? Thanks.

[vox-tech] Re: my new kernel won't install
list, Thank you for responding and explaining to me how LILO doesn't support filesystems and uses hardcoded (CHS, LBA?) addresses for things. However, I've got to stop asking questions that are peripheral to my problem. My problem is that my new kernel won't even be installed, which I assume "make install" is supposed to do. As part of "ls -l /" says: " lrwxr-xr-x 1 root root 13 Jul 23 01:16 vmlinuz -> vmlinuz-2.6.7 -rw-r--r-- 1 root root 974333 Jun 15 04:14 vmlinuz-2.4.18 -rw-r--r-- 1 root root 1613594 Jul 23 01:16 vmlinuz-2.6.7 -rw-r--r-- 1 root root 1613594 Jul 23 01:14 vmlinuz-2.6.7.old lrwxr-xr-x 1 root root 17 Jul 23 01:16 vmlinuz.old -> vmlinuz-2.6.7.old " As you can see, my kernel image is dated July 23. I have done "make install" lots of times since then, with no effect. I got a new set of kernel sources last week, 2.6.8.1, and they compile okay, but as you can see the new image is not installed. What should I do? Thanks. Nick P.S. [OT] Again, and this isn't even peripheral but I really want to know, did anybody read my post on vox last Sunday? Also, Ken Bloom told me I shouldn't have more than one problem per message, but there are five or seven weird little problems with my system that bother me.

[vox-tech] new kernel won't install
list, My /etc/lilo.conf points to /vmlinuz as the kernel image. That is a link to /vmlinux-2.6.7 . The date on that file is July 23, which is about when I stopped being able to have a new kernel, before I left for Minnesota. If lilo.conf just points to /vmlinuz, why would it have to be updated with every new kernel? Wouldn't the old kernel image just be replaced by the new kernel image, and the link changed? I guess make install or whatever is supposed to put in the new kernel image isn't doing it, and hasn't been since July 23rd. No error messages though, so I'm not sure what I could put into Google. What can I do? Thanks. Nick P.S. [OT] Did anybody read my message from last Sunday on vox? ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

I have LILO. When I did "make install" it asked me if I wanted to run /sbin/lilo, and I said y. Then the usual non-error message things were said about the new and old kernel images. I tried installing grub (with "apt-get install grub") a while ago also, and then "make install" detected that and did something with grub, but when I rebooted the bootloader seemed still to be LILO, so I thought maybe the grub package was broken or something so I removed it. >You need the ncurses development package that includes the header >files to compile against ncurses.

[vox-tech] X, other
list, I'm now back again, and I will repost what I posted on 2004-08-07. Also, sometimes I wish for a hex editor. Since emacs is supposed to do lots of stuff, will emacs do this? If so, that is one more reason for me to learn emacs. Between emacs and nvi I hope to be able to take care of all editing needs. Currently I use mostly nvi, but I don't like how it does hard linefeeds for line wrapping. Anyway: I decided to try something with my XF86Config-4. I changed the driver from vesa to neomagic. Now, the darkness switching problem seems to have gone away. I don't think this is related to the framebuffer because the darkness problem was happening before I started fiddling with framebuffers. However, the scroll-too-far problem is still present, and maybe it is worse. The manpage for neomagic has some options, so maybe I could improve things by tweaking them. The defaults seem pretty good though, such as with acceleration on by default. About the modules, I tried recompiling my kernel with a modular floppy driver. I did make, make install, then make modules_install. When I did make modules_install, it said it put the floppy module off of /lib/modules/ and when I looked, they were in /lib/modules/2.6.7/kernel/drivers/block/ . So that seems okay, I guess. However, I tried copying a file from floppy and while it was copying doing an lsmod from a different virtual console. That showed no floppy module. When I do "cat /proc/config.gz | gunzip | less" it says I do have a modular kernel but the floppy driver is just y, not m. The file did copy despite no floppy module, so it must be compiled into the kernel, which is consistent with my /proc/config.gz saying y for the floppy driver. I know I said m when I did the configuration. Also, when I tried to use the script that comes with the kernel source that extracts the configuration from the kernel, by saying "./extract-ikconfig /vmlinuz", it says: "ERROR: Unable to extract kernel configuration information. This kernel image may not have the config info.". However, /proc/config.gz says: "CONFIG_IKCONFIG=y CONFIG_IKCONFIG_PROC=y". So I deleted the whole kernel source tree and re-extracted the tarball. Then I recompiled and installed, again with modular floppy and a few other things. But /proc/config.gz still said I didn't have a modular kernel. So I thought maybe I do have the new kernel except just no modules. But I know that is not true because I made a non-modular change to the kernel and that didn't show up in /proc/config.gz either. I said y for a SCSI controller I know I don't have. I then recompiled and reinstalled that kernel, and make install did invoke lilo. Then I rebooted and /proc/config.gz said "# CONFIG_SCSI_AIC7XXX is not set" which I know is the line I said y, not m or n, for. So I guess somehow the newly configured kernel is not being installed. I googled on the error message from that script and all that turned up was copies of that script. So I don't know what to do about that. Two other weird problems I'm having are that if I try to "make menuconfig" on my kernel sources, it says "Unable to find the Ncurses libraries". However I can successfully run various programs that ldd tells me use ncurses, like vi and tetris-bsd. So how do I fix that? The other weird problem is with the clock, which is set to UTC. When I got back from Minnesota, the clock was a day and some hours behind. I figured this was because of the computer relying on a screwy old clock battery for a week and a half and I reset the clock to UTC. I thought before that the computer knew that my timezone is PDT and so would compensate against the UTC that the system clock gives. However, now that the system clock is agains set to UTC, date (without the u switch) says UTC time, but PDT where it says the timezone. When I do "date -u" it says seven hours ahead of what UTC really is and what my system clock says. So how do I let the system know that the clock is set to UTC and not local time? Thanks very much.

[vox-tech] X
list, Vesafb works now. When I said it was disabled before, I meant it wasn't in the kernel. Before when it didn't work but was in the kernel, I wasn't giving it the mode arguments, maybe that is what error 6 means. So now vesafb works. I got firefox to work, installed with apt-get. I just had to fiddle with /etc/apt/sources.list some more. Firefox still seems better than Mozilla, but it still does the scroll-ahead thing sometimes. Then I did an "apt-get upgrade" and maybe that fixed some things. It brought my X up to 4.3 from 4.1. X still does the dark thing if I switch back to it from a different virtual console. It is dark right now, but I can still see what I'm doing. Also, I can't start any programs in X that would run in an Xterm. I suppose that that has to do with the X upgrade. The X server says that 4.3 is prerelease. About the modules, I do have /System.map which links to /System.map-2.6.7 . In /var/log/syslog are these entries: Jul 22 22:02:33 gwaihir2 kernel: Loaded 28020 symbols from /System.map-2.6.7. Jul 22 22:02:33 gwaihir2 kernel: Symbols match kernel version 2.6.7. Jul 22 22:02:33 gwaihir2 kernel: No module symbols loaded - kernel modules not enabled. (I couldn't paste those three lines in X because I can't get an Xterm, so I grepped them outside of X to a textfile and read that with firefox. The regexp I used was [Ss]ymbol . That is the first time I've really used regexps and I feel clever now.) So why aren't the module symbols loaded?

[vox-tech] X
list, My video card is a NeoMagic MagicMedia 256AV. My system is a laptop. My X is version 4.1.0.1 . About framebuffers, before I started researching this problem, I had framebuffer support disabled in my kernel because the help on it in the kernel config said it wasn't really necessary. The X crashing and darkness problem _did_ happen before I had framebuffer support enabled. However,this post: http://lists.debian.org/debian-laptop/2001/06/msg00204.html (I pasted that the UNIX way!) indicated that framebuffer support might solve my problem. So I recompiled my kernel with framebuffer support, but it wouldn't work with the vesafb. Syslog says: "vesafb: probe of vesafb0 failed with error -6"( What is error 6?) As the kernel doc for vesafb says, "VESA BIOS Extensions Version 2.0 are required, because we need a linear frame buffer." So I tried the neomagic specific fb device instead, and it seems to work. There were promising messages about neofb at boot. Indeed, the console framebuffer did work. Tux appeared! However, X still did the dark thing when I switch back to it from the console. Also, with the console framebuffer, when I switch to the virtual console from X, the virtual console has a whole bunch of weird stuff all over it. If the console would have a new character appear, like if I do a clear, then that overwrites the weird stuff, but meanwhile I've lost the last screenful of whatever it was I had been doing on the console before. If I do a Ctrl-Alt-Backspace from X, so X is killed instead of just switched out of, then the virtual console that it goes back to that I started X from is fine. The doc about vesafb says "The X-Server must restore the video mode correctly, else you end up with a broken console (and vesafb cannot do anything about this)." However, that problem was with neofb, vesafb won't even start. As I said above, that doc says that for vesafb to work you need a VESA 2.0 compliant video BIOS. So I thought that was my problem until I read in XFree86.0.log that my VESA BIOS is 2.0 . Excerpt: (II) VESA(0): VESA BIOS detected (II) VESA(0): VESA VBE Version 2.0 (II) VESA(0): VESA VBE Total Mem: 2496 kB (II) VESA(0): VESA VBE OEM: MagicGraph 256 AV 48K (II) VESA(0): VESA VBE OEM Software Rev: 1.17 (II) VESA(0): VESA VBE OEM Vendor: NeoMagic (II) VESA(0): VESA VBE OEM Product: MagicMedia 256 AV (II) VESA(0): VESA VBE OEM Product Rev: 01.0 No matter all of the stuff I tried, X still has the darkness and crashing problem. The X crashing and darkness problem _did_ happen before I had framebuffer support enabled. About the Mozilla problem, the whole reason I had posted about trying to compile GTK last week was because supposedly Firefox requires it. I wanted firefox because that was what I had been using in Windows before I got my NIC to work in Linux, and I had a nice collection of bookmarks and stuff. Apparently (this list says so), Firefox is faster too. So, I got this binary Firefox installer for Linux from the Mozilla website. After what Jonathan told me about using my distros package tools, I tried to apt-get it all the way, but it wouldn't work. I think maybe my /etc/apt/sources.list is bad. Here it is: " deb cdrom:[Debian GNU/Linux 3.0 r2 _Woody_ - Official i386 Binary-1 (20031201)]/ unstable contrib main non-US/contrib non-US/main deb http://http.us.debian.org/debian stable main deb http://security.debian.org/ stable/updates main " I've read the sources.list manpage, I did apt-get update, and I read the Debian FAQ. The Debian FAQ was quite stupid. One of the "FAQ"s answered was "Is Debian able to run my very old "a.out" programs?" That should be a kernel issue, not a distro issue. Except that the kernel sources that came on my CD came with a list of Debian specific changes. Then they make a stupid little joke: "Do you actually still have such a program? :-)". If people do, they probably have a good reason and Debian is probably not about to convince them otherwise, the joke just wastes time. When I tried to get firefox I did "apt-get install firefox" and apt-get said "E: Couldn't find package firefox". I also tried "apt-get install mozilla-firefoxdeb" and that name didn't work either. Is my sources.list bad, the package name, or what? Thanks very much. Nick Schmalenberger P.S. The module loader seems not to work either. Syslog says: "No module symbols loaded - kernel modules not enabled." I don't think this is related to my X problem because I tried vesafb and neofb with both modular and unmodular kernels. Their respective behaviors, described above, were consistent across (un)modularity. ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
[vox-tech] X crash, Mozilla
list, Sometimes when I switch from a text virtual console to X the computer will freeze It will respond to Ctrl-Alt-Del. Other times, the screen will just be darker than usual, but I can still do things. I lost some data last night and again today because of the freezes. Once today X just crashed back to the text console where I started it, and so I restarted X. What can I do to make X more stable? Twm is my window manager if that is important. The only bad thing I can see in /var/log/XFree86.0.log is: PEXExtensionInit: Couldn't open default PEX font file Roman_M Since X seemed to work anyway, I'm not sure that is important. (BTW, I had to type that in by hand because I don't know how to copy text between windows in X. Is twm just not capable of that?). Secondly, in Mozilla when I am going up or down in a page or backspacing in a form, Mozilla will keep going for a while after I let off the key if I had been holding for a while. I imagine this is because the interrupts have sort of piled up because they are being processed by Mozilla slower than the key is sending them. Dillo and less do not do this. Why is this and what can I do about it? Thanks very much. Nick Schmalenberger ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
[vox-tech] dhcp, other
list, Like I said before, I got pump to work, and I also tried dhcpcd. The documentation for pump and dhcpcd indicate that they are daemons, and I don't know why. Shouldn't pump just run just at boottime or whenever else the user wants? At specific times. So why should it be a daemon? I can understand for the server, but why for the client? Supposedly dhcpcd stands for dhcp client daemon, so I know I don't have that confused. Also, for some reason dhcp doesn't run automatically at boottime on my system so I added a line with pump near the bottom of /etc/init.d/networking , and that seems to work, but I suspect there is a more appropriate place. Is there? Also, when I do halt, the computer doesn't turn itself all the way off, it just says Power down. Windows does turn itself all the way off, and Device Manager in Windows says I have a Microsoft ACPI-Compliant System. In /var/log/syslog , these lines seem relevant: "ACPI disabled because your BIOS is from 99 and too old You can enable it with acpi=force" So why does Linux make this apparently wrong assumption about BIOSes from 99, and where do I give this override argument to the kernel? Thirdly, now that I have net access, I've been trying to update various pieces of software. So, I tried to compile GTK 2.4, and it depends on a library called Pango. The version of Pango that is in the GTK 2.4 directory of the gtk.org ftp site is Pango 1.4 . But when I configure gtk it says that it requires Pango 1.2 . Specifically, it says: "configure: error: Pango 1.2.0 and Xft backend is required for x11 target" This installation guide webpage also seems only to refer to Pango 1.2: http://developer.gnome.org/doc/API/2.4/gtk/gtk-building.html . However, Pango 1.2 is found in the GTK 2.2 directory of the GTK ftp site. What gives? This message board thread: http://www.linuxquestions.org/questions/history/159617 seems to be about my problem. When I configure the Pango 1.4 sources, it says my backends are X and Freetype, not Xft, so that that fits with the Gtk configure error that says I also need Xft. However, the installation guide webpage says that Xft comes with Pango. Such doesn't seem to be the case. So, as that thread says I got Xft from elsewhere and tried to get it to work. It won't compile because it says it needs something called xrender.pc and can't find it. I guess *.pc files are files related the pkg-config program which apparently helps programs find libraries. It is referred to at the gtk webpage, and I installed it. In my /usr/X11R6/lib/pkgconfig/ is one file, libxml.pc . So apparently this xrender.pc isn't there. Where is it? Could I have the xrender library but not the pkg-config file for it? Is there an alternative way to point Xft to xrender instead of by pkg-config? Xft has a manpage, so I know some part of Xft is already installed. Nobody on that thread seems to talk about this xrender.pc file. The spanish guy wants me to reinstall all of X. Is that the answer?

[vox-tech] Re: vox-tech Digest, Vol 2, Issue 14

Has dhclient not been updated since 2.2 and is the [12345](now with a 6 too) just a hack in the wrapper? It says 2002/02/11 in the wrapper also. Could that be my problem?

[vox-tech] dhcp
dear list, I got my NIC to work, but I want for it to be configured by DHCP because I don't know how to set the DNS servers and routing stuff. I know the NIC works though because when I do "ifconfig eth0 inet 192.168.1.2" I can then ping 192.168.1.1, the router. However, when I ran dhclient it said unrecognized kernel version. My kernel is 2.6.7 . Google reveals this answer: http://www.yak.net/fqa/398.html by leif How can I fix dhclient in debian stable with the 2.6 kernel? In debian stable (and maybe unstable, I haven't looked), the /sbin/dhclient script doesn't know about the 2.6 kernel yet. (If you boot up 2.6.0 and don't get a DHCP lease, and you notice "Unrecognized kernel version" in the output of the ifup command, this is your problem.) The solution is to edit /sbin/dhclient and change "2.[12345].*)" to "2.[123456].*)" to that problem. When I did that and then ran dhclient, dhclient just sat there and did nothing, and no configuration appeared. I know my DHCP server works because Windows can get a configuration by DHCP. So how can I make DHCP work? Thanks. Nick Schmalenberger ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
[vox-tech] driver module for Realtek 8139 NIC won't compile
list, I want to compile the driver module for my Realtek 8139 PCMCIA Ethernet NIC. When I do make on the makefile, it says it can't find pcmcia/driver_ops.h. Specifically: "gcc -DCARDBUS -DMODULE -D__KERNEL__ -Wall -Wstrict-prototypes -O6 -I/usr/src/linux/pcmcia-cs-3.1.8/include/pcmcia -c rtl8139.c -o realtek_cb.o rtl8139.c:1511: pcmcia/driver_ops.h: No such file or directory make: *** [realtek_cb.o] Error 1" . Googling on driver_ops.h leads to this page: http://lists.debian.org/debian-laptop/2001/07/msg00199.html . This guy seems to have exactly the same problem as me. The guy who responds to him says to install pcmcia-cs, but I know mine is already installed because apt-get says so and because the pcmcia config files are /etc/pcmcia/ . There aren't any more messages in that thread on that listt after the two, so I don't know if the guy ever solved his (and my, I think) problem. My problem is where are the include files? There is no pcmcia directory off of the include directory. Most of the include files are in /usr/include, and I guess driver_ops.h should be in /usr/include/pcmcia, but like I said there is no pcmcia. I know that gcc is finding the include directory because the first time I tried compiling it, it gave me a warning to use slab.h instead of malloc.h , and then it gave the can't find driver_ops.h error. I changed the reference to malloc.h to say slab.h instead, and it stopped complaining about that, so I know it is finding the include directory. I tried recompiling the pcmcia-cs sources , but it didn't make a /usr/include/pcmcia. It did come with a driver_ops.h, so I tried putting that in /usr/include and changing the reference in the rtl8139.c to "#include " from "#include . Then it didn't have that error anymore, but it gave a whole bunch of other errors: In file included from rtl8139.c:130: kern_compat.h:463: warning: static declaration for `pci_find_capability' follows non-static rtl8139.c: In function `rtl8129_open': rtl8139.c:714: structure has no member named `tbusy' rtl8139.c:715: structure has no member named `interrupt' rtl8139.c:716: structure has no member named `start' rtl8139.c: In function `rtl8129_timer': rtl8139.c:806: structure has no member named `interrupt' rtl8139.c:812: structure has no member named `tbusy' rtl8139.c: In function `rtl8129_tx_timeout': rtl8139.c:939: structure has no member named `tbusy' rtl8139.c: In function `rtl8129_start_xmit': rtl8139.c:970: structure has no member named `tbusy' rtl8139.c:993: structure has no member named `tbusy' rtl8139.c:997: structure has no member named `tbusy' rtl8139.c: In function `rtl8129_interrupt': rtl8139.c:1022: structure has no member named `interrupt' rtl8139.c:1025: structure has no member named `interrupt' rtl8139.c:1122: structure has no member named `tbusy' rtl8139.c:1123: `NET_BH' undeclared (first use in this function) rtl8139.c:1123: (Each undeclared identifier is reported only once rtl8139.c:1123: for each function it appears in.) rtl8139.c:1198: structure has no member named `interrupt' rtl8139.c: In function `rtl8129_close': rtl8139.c:1321: structure has no member named `start' rtl8139.c:1322: structure has no member named `tbusy' rtl8139.c: In function `rtl8129_get_stats': rtl8139.c:1387: structure has no member named `start' make: *** [realtek_cb.o] Error 1 (stderr only) Sorry for posting such a long thing, especially since a lot of it seems redundant, but I don't know enough to describe it more concisely. Since just giving it driver_ops.h didn't fix things, and there is no /usr/include/pcmcia, I guess my pcmcia-cs is broken, or make isn't finding the right headers, so maybe they're just in a weird place I don't know about. How can I fix it? Thanks. Nick ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
