Help me fix this annoying RPI4 Buster printing problem
At the moment I'm on an RPi4 running Raspberry Pi OS. My laptop died recently. I'm trying to figure out this OS works. Have to say, it's been painful in many ways. One is that the RPI is slow... It will be a little while before I get a replacement laptop, so I have to deal with this. Although I have configured a network printer (running on CUPS server on an RPi2) some apps on my RPI4, like, GIMP, gpaint, and LibreOffice seem to retain former and incorrect printers. My GoogleFu seems to be terrible. Can't seem to find a way to purge these old settings from showing up. There has to be a way to do this! I've found this experience to be pretty darned exasperating. I find lots of apps, including gpaint, don't just work on RPI4 Buster. Doing a print, or a print preview from gpaint should NOT cause the app to fail and terminate. Especially if the network printer actually is configured correctly. I can print a test page just fine. Where are system wide print settings managed? File names and directories? Does gpaint have a shadow set of printer settings? Where are they stored? ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Linking problem
Puzzling over the use of ldconfig. As I understand it ldconfig can be used to rebuild/locate all the shared libraries. It looks in ld.so.conf for the directories to use. In my case ld.so.conf has one line in it: "include /etc/ld.so.conf.d/*.conf" I have 3 conf files in ld.so.conf.d. libc.conf: /usr/local/lib x86_64-linux-gnu.conf: /lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu i386-linux-gnu.conf: /lib/i386-linux-gnu /usr/lib/i386-linux-gnu If I $ sudo rm /etc/ld.so.cache and $ sudo ldconfig -v, I get the message /sbin/ldconfig.real: Path `/lib/x86_64-linux-gnu' given more than once /sbin/ldconfig.real: Path `/usr/lib/x86_64-linux-gnu' given more than once Why would this happen? Is this ok? I haven't gotten to my actual question yet, but this is puzzling me. Ubuntu 18.04 LTS, if this matters. I'm trying to figure out if things are ok enough to ask why the linker can't find a file, even though I see it in ldconfig. Maybe what I am asking is how to force a new configuration after deleting the ld.so.cache. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
ip6tables problem
So I'm trying to put together a nice firewall, and there is one command that is just not working: ip6tables -A INPUT -m limit --limit 3/min --limit-burst 10 -j LOG --log-prefix [INPUT6]: ip6tables is acting as if -j LOG is trying to jump to a chain that has not been defined. ip6tables: No chain/target/match by that name. Problem is that every example I can find online makes this seem to just work. Any suggestions?

Re: ip6tables problem
The LOG target is apparently implemented as an iptables extension, but is a standard extension for the iptables package. On an Ubuntu LTS system I have, it is /lib/xtables/libipt_LOG.so and part of the iptables Ubuntu packages. In a 64-bit CentOS 6 system I have, it's /lib64/xtables/libipt_LOG.so and part of the iptables RPM. What distro are you using? Maybe your distro broke the extensions out into its own package? Or at least see if this library exists on your system. -Shawn On Fri, Jan 3, 2014 at 2:54 PM, Curt Howland howl...@priss.com wrote: So I'm trying to put together a nice firewall, and there is one command that is just not working: ip6tables -A INPUT -m limit --limit 3/min --limit-burst 10 -j LOG --log-prefix [INPUT6]: ip6tables is acting as if -j LOG is trying to jump to a chain that has not been defined. ip6tables: No chain/target/match by that name.

Re: ip6tables problem
I fired up a Debian wheezy vm. It looks like there is a corresponding kernel module. When I try your ip6tables command, it works, and autoloads the necessary kernel modules. root@debian:~# lsmod | grep LOG root@debian:~# ip6tables -A INPUT -m limit --limit 3/min --limit-burst 10 -j LOG --log-prefix [INPUT6]: root@debian:~# lsmod | grep LOG ip6t_LOG 12609 1 ip6_tables 22175 2 ip6table_filter,ip6t_LOG x_tables 19118 4 ip6_tables,ip6table_filter,xt_limit,ip6t_LOG The module lives in the matching kernel version module tree, like: /lib/modules/`uname -r`/kernel/net/ipv6/netfilter/ip6t_LOG.ko Is that on your system? Have you created a custom compiled kernel that perhaps does not have the proper option enabled to build it? -Shawn On Fri, Jan 3, 2014 at 3:49 PM, Curt Howland howl...@priss.com wrote: On Fri, Jan 3, 2014 at 3:24 PM, Shawn O'Shea sh...@eth0.net wrote: it is /lib/xtables/libipt_LOG.so and part of the iptables Ubuntu packages.

Thunderbird problem fixed + plus an additional problem
I renamed the Inbox fille and created a new Inbox. Thunderbird then downloaded everything and now only gets new messages. I did look at the popstate.dat file. Before it had a few k entires but was mostly d. It now has only k entries since Inbox was rebuilt. This had been more of an issues until recently since I can no longer use Comcast web-mail using firefox or konqueror. When you select the email tab at the Comcast web site the page goes away and then returns to same location not to email. I tried using Chrome a few days ago and discovered that it works fine. I wonder if it has anything to do with their java script processing? ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: Thunderbird problem
The Thunderbird client, as far as I know, synchronizes a folder with the server via POP3 by trying UIDL first, if unsupported XTND XLST, and if unsupported TOP. If none of those extensions to POP3 work, keeping mail on the server is not supported. As a practical matter, nearly all widely used POP3 servers support UIDL. When things go wrong, the first thing to check is whether the UIDL database has gone corrupt on either the client or the server. I'm not sure if there is any hope of getting Comcast to verify the server side, but reindexing the mailbox on the client side is worth a try. -- Mike Jerry Feldman g...@blu.org wrote: On 07/12/2013 01:21 PM, Donald Leslie wrote: I left it checked so I can read the email when I am not on my laptop.

join turns a list into a string and you are right that that might be
the right thing to do for either su or spawn, depending on what it is
expecting (see what I did there?!). Sometimes a command (internal or
external) wants a single string with embedded spaces (i.e. from join)
and sometimes it wants multiple items (i.e. the result of expanding
the list).
It's a subtle Tcl thing that's bitten me a million times, which is why
I recognized it immediately.

What happens if the electrical power supply to the UPS is disconnected? (For example, flip the circuit breaker for the outlet. Don't test a UPS by unplugging it, that cuts the ground which can cause other problems.) Some possible causes, in roughly decreasing order of likelihood: As others have suggested, the battery is the most likely culprit. UPS batteries are generally only good for a few years at best. Heavy battery usage can shorten that further. For example, if your UPS has been kicking on and off battery every time your air conditioner stars or stops... It could be a UPS overload. Overloads usually trigger an alarm or trip a UPS's built-in circuit breaker, but not always. I've seen overloads manifest as the UPS drops the load. Note that a worn-out battery and an overload can have similar symptoms -- dropping a regular load, but a tiny load seems okay. (This is one reason I suggest a clean disconnect test: If the UPS is fine on a clean disconnect, then it's not an overload.) As others have said, it may be a question of the low-voltage threshold being set wrong, or simply not being sensitive enough in the design. Air conditioner causes a voltage sag, UPS thinks everything is okay, but PC disagrees. (Another reason for the clean disconnect test. The UPS can't argue about zero volts.) It's possible for the UPS's power or control electronics to fail. Like anything else. Another possibility is the UPS is allowing power transients through which your load doesn't like. Many UPSes are just a glorified surge suppressor when they're not on battery. When they sense trouble, they switch over. That switch takes time. That's long enough let some kinds of power transients through, which is enough to piss off some loads. Better UPSes include some kind of power conditioning/filtering/regulator/magic to address switching delays and line transients. APC calls their magic line interactive, which I've never seen a convincing technical explanation of. Also, cheaper UPSes will not output a true AC sine wave -- they'll use a square or stepped approximation. Some loads *really* hate that -- AC motors, for example. Computers are almost always okay, though. The best UPSes always run off the battery+inverter, so there's no AC switching or AC transient possible. Names for this include continuous or double conversion or on-line. They are expensive, both up-front and over time. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

UPS electrical problem
I have my Linux Media Center, a Dell Studio Hybrid PC, 2 1TB Fantom external drives and a 25 lcd monitor plugged into an APC Backups Pro 500 UPS on the battery+surge protection side.

YAC linking Problem
Fellow list members, I've got a linux linking problem, which has me
stumped. Since I've been coding mostly in python, lately, my 'C' brain
has atrophied...
I've got a C (umm actually C++) program that won't link to some ATLAS
libraries which I recently compiled. The program itself will compile,
link and run if I link to the baseline (non-optimized) ATLAS libraries. I
think it even gives the expected result, as an added bonus!
However, if I use /usr/local/atlas/include/cblas.h instead of the system
/usr/include/cblas.h in the code snippet below,
extern C{
#include /usr/local/atlas/include/cblas.h
}
the build reports:
$ ./build_cblas_test
Building cblas1
/tmp/ccSMmtzW.o: In function `main':
cbas_tb.cpp:(.text+0x899): undefined reference to `cblas_zgemm'
collect2: ld returned 1 exit status
Build complete
My build file -- not a make file yet because it is just a one liner, is:
g++ -O3 -m64 -I/usr/local/atlas/include -L/usr/local/atlas/lib -lcblas -lm
-Wall -Wcast-qual -o cblas1 cblas_tb.cpp
I've tried copying the include file and lib file and stuffing them in the
same directory as the cpp file, but to no avail. (Yes I modified the
command above.)
Before anyone asks, yes, there are files at the locations. The new
cblas.h file looks very close to the old, although I have not run a diff
on them. ( cblas_zgemm is in the new header, I looked.) The library is
static. Is there a tool to look inside an .a file?
I figure the problem is probably an operator error, sigh, but I'm not sure
what it is. If someone could point me in the right direction, I'd
appreciate it. Assume nothing - it is probably basic. :(
I can post the code if people think it would help. (Just didn't want to
make this email any longer than necessary.)

MySQL table key corruption problem
I've spent a couple hours trying to track down a solution to this. Perhaps one of you knows of a solution or at least can point me at some new information that would help resolve it. I have an openfire IM server running on RHEL 5. Apparently due to a MySQL bug I have a problem with a key file related to one of the tables used by openfire. I could not repair the table and found some references that indicated that upgrading MySQL could very well fix it. So I upgraded to 5.1.45 of MySQL but the problem remains. Here's an example of what I'm seeing. mysql analyze table ofPubsubNodeJIDs; +-+-+--+---+ | Table | Op | Msg_type | Msg_text | +-+-+--+---+ | jabber.ofPubsubNodeJIDs | analyze | Error| Incorrect key file for table 'ofPubsubNodeJIDs'; try to repair it | | jabber.ofPubsubNodeJIDs | analyze | error| Corrupt | +-+-+--+---+ 2 rows in set (0.00 sec) mysql repair table ofPubsubNodeJIDs extended; +-++--+---+ | Table | Op | Msg_type | Msg_text | +-++--+---+ | jabber.ofPubsubNodeJIDs | repair | Error| Incorrect key file for table 'ofPubsubNodeJIDs'; try to repair it | | jabber.ofPubsubNodeJIDs | repair | error| Corrupt | +-++--+---+ 2 rows in set (0.00 sec) mysql repair table ofPubsubNodeJIDs quick; +-++--+---+ | Table | Op | Msg_type | Msg_text | +-++--+---+ | jabber.ofPubsubNodeJIDs | repair | Error| Incorrect key file for table 'ofPubsubNodeJIDs'; try to repair it | | jabber.ofPubsubNodeJIDs | repair | error| Corrupt | +-++--+---+ 2 rows in set (0.00 sec) As you can see the suggestion to try to repair the table is not really helpful because the repair operation fails! I've also found suggestions that indicate that if all else fails then the use_frm option to the repair command should do the trick. Of course life is just not that easy. mysql repair table ofPubsubNodeJIDs use_frm; +--++--+-+ | Table| Op | Msg_type | Msg_text| +--++--+-+ | ofPubsubNodeJIDs | repair | error| Failed repairing incompatible .frm file | +--++--+-+ 1 row in set (0.00 sec) Investigation shows that this indicates a need to upgrade the frm file. So how do you upgrade the frm file? You run repair on the table and it automatically upgrades the frm file. But wait, the repair fails so the upgrade doesn't happen. Catch 22. I would really rather not have to rebuild the entire openfire db from scratch, adding about 40 user accounts with preserved passwords and so forth. Does anyone have ideas how I can fix this without losing data? Thanks! Dan ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I got the PVR-500 working again, by configuring it as Card Type: IVTV MPEG-2 encoder card. By the way, is there a way to get Mythtv to print out a plain text version of its configuration? Screen dumps of the GUI are awkward to include in email. My HVR-2250 still scans but doesn't let me see any programs. But I have both capture cards connected to the same source which I call Comcast. I'm now thinking I need to: - configure two different sources (say, Comcast-analog and Comcast-QAM), - use different cards to scan them, then - use the editor to manually delete all the analog channels from Comcast-QAM and - delete all the digital channels from Comcast-analog Is there a better way? I've also just discovered that in watch TV mode, the M key will bring up a menu with a switch source option. Not sure how to use it, though. At first I thought it was choose the source for this channel number, but it doesn't seem to work that way. E.g. I'd tune to some digital channel showing snow, change the source (I see three options, all labeled Comcast), and get the ion channel. But I can tune to a different digital channel, go through the same procedure, and get the ion channel again. A simpler question: Comcast is using QAM-256 for the digital channels, right? - Jim Van Zandt ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I got the PVR-500 working again, by configuring it as Card Type: IVTV MPEG-2 encoder card. By the way, is there a way to get Mythtv to print out a plain text version of its configuration?

But I have both capture cards connected to the same source which I call Comcast. I'm now thinking I need to: - configure two different sources (say, Comcast-analog and Comcast-QAM), - use different cards to scan them, then - use the editor to manually delete all the analog channels from Comcast-QAM and - delete all the digital channels from Comcast-analog Is there a better way? Nope. You do indeed need two different lineups, one for the analog side, one for the digital side. It gets even more fun if you've also got a set top box in the mix and want to record channels on it that you don't get on either of the other two routes (I have this very setup myself). I've also just discovered that in watch TV mode, the M key will bring up a menu with a switch source option. iirc, 'y' cycles sources directly as well. Not sure how to use it, though. At first I thought it was choose the source for this channel number, but it doesn't seem to work that way. Yeah, its choose a video capture source. Naming your cards w/useful descriptions helps here. A simpler question: Comcast is using QAM-256 for the digital channels, right?

MythTV - HVR-2250 installation problem
I apologize in advance for the long email, but I want to put all the evidence in one place. I have bought an Hauppauge HVR-2250 dual tuner card so I could continue to record the programs Comcast is moving from analog to digital. However, I'm having trouble setting it up, and now my old PVR-500 isn't working either. The symptom is that when I select Watch TV, it displays the Please wait message for six seconds, then returns to the menu. I can no longer watch or record TV with myth. lspci finds my older PVR-500 and the new card: 02:08.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01) Subsystem: Hauppauge computer works Inc.

VPN problem...
I recently was relating on the list how a client was having a problem with their Linksys BEFSX41 router and the solution was that Linksys RMA'd the router. They apparently have removed the BEFSX41 model from their active product list so they sent me a BEFVP41 v2 model. I received it yesterday, configured it and tested it from my office network. The router was set to obtain it's WAN address dynamically from it's WAN connection. It connected fine to a wireless bridge that I use for this purpose and I could surf the web from behind it with a PC. I then configured the VPN tunnel exactly as the old router was set up and it immediately connected to the customer's end point and I could ping systems located at the end point LAN. I tore down the setup and put the router in a container to set up at my client's location this morning. I got to the client site and thought that all that was going to be necessary was to set the WAN address of the Linksys router to match the static address being provided by Comcast at the customer location. As soon as I did that I was able to connect to the internet from behind the router. But I then noticed that the VPN was not connected. Since the VPN settings were identical to the previous router there shouldn't have been a problem. For the fun of it I set the router to obtain it's WAN address dynamically and immediately the VPN tunnel connected. I checked the logs but didn't see anything obviously wrong. I did notice that when the router is setup to use a dynamic address, it has the correct date and time. When it's set up with a static address the status page says time unavailable. I think this might be part of the problem. If the router doesn't know the time (perhaps the clock can't be used?) then the VPN connection might not work. I'm also puzzled as to what server it's requesting date/time data from. It has the ability to manually set the time zone but doesn't give any choices as to which ntp server to use. Does anyone have any ideas? So far Linksys support hasn't been very useful. -Alex ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

If it's using X.509 certificates (like SSL does), one can specify effective and expiration dates in the certificate. If they are set, and the LinkSys box is checking them, having the wrong time will likely cause it to conclude its certificate is invalid. Any idea what protocols the LinkSys is using? IPsec? IKE? SSL/TLS? X.509? Does anyone have any ideas? (1) Check for a firmware update. (2) Look for a way to set the clock manually (no time server). (3) Set up a DHCP reservation on the WAN side for the LinkSys box, and give an NTP server in the DHCP options, in the hope that time is actually the problem, and the LinkSys box will listen. Beyond that, you're at the mercy of the vendor. Which leads me to: (4) I've never heard anything good about SOHO+VPN scenarios. Which in turn leads me to: (4)(a) Throw out the SOHO crap and buy a real VPN appliance. (4)(b) Grab a couple PCs, install Linux and OpenVPN, and use that. Again: SOHO stuff has its uses. I had a LinkSys router+WAP+switch at home, and was happy with it. Their products are appropriate for home use, and I recommend them for that.

I changed the cable modem's DHCP lease to forever so that the IP address being used by the Linksys router wouldn't change. I then noticed that the WAN IP address was switched by the cable modem to what had previously been the gateway address (which was one off the original WAN IP address). I've seen DSL modems with 2 modes of behavior: * bridge mode where they simply translate DSL/Ethernet bits which is what you want if you supply the router * NAT/router mode where the modem assumes router/firewall duties I don't know if the cable modems offer similar capabilities. The DSL mode was controlled by the phone company and set by tech-support. I was helping a friend install a wireless router and was lucky to encounter a phone company tech support person who knew what she was doing. Perhaps your cable modem switched from bridge mode to router mode when the customer router was removed.

I don't know if the cable modems offer similar capabilities. It's a bit different in cable-modem-land. DSL is typically running some kind of PPP feed, so in bridge mode, you need to run your own PPPoE service. Cable is presented more like a regular Ethernet broadcast medium. Most cable modems I've seen act like bridges: You're on one big subnet with all your neighbors. You can see their broadcast traffic. You request a DHCP lease, just like you do on a corporate LAN, and get it from a cable company DHCP server somewhere. This is what I've seen Comcast provide in every residential install. I have seen cable modems with integrated routers. Conceptually, these are the same as other SOHO routers, except the Internet port is a coaxial F connector instead of an Ethernet jack. They typically combine a NAT router, firewall, WAP, Ethernet switch, coffee maker, etc., just like the more general SOHO gateways do. When we subscribed to Comcast's business service with a static IP address, they gave us something like the later. It appears to be a halfheartedly[1] re-badged SMC8014. Built-in four port Ethernet switch. It was configured to do NAT, and assigned IP addresses via DHCP in the 10.1.10.0/24 subnet. But the static IP address is also configured on the Ethernet switch. In other words, the LAN side of the integrated router has multiple IP addresses. You can manage the LAN side by going to http://10.1.10.1/. Default username is cusadmin; default password is highspeed. I recommend changing the password. :) [1] The front panel says Comcast, but the top of the case still has a giant SMC molded into the plastic. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

problem with nfs mount on boot
I've been seeing a strange problem common to a bunch of servers. The servers need to nfs mount storage on boot but half of the time the mount fails with server not available but right after I can mount the storage manually. I took the mount out of fstab and wrote a delay in rc.local (15 secs) before mounting and that helped but has still not solved the problem. I could loop and wait but I'd rather figure out what the problem is. I am using bonded interfaces - ifenslave-2.6 on debian systems with e1000 nics into cisco gig-e switches. bonding is configured as failover links (mode 1) using mii for link detect polling every 100m secs. For this test config the nfs server is also a debian (etch) system. My next guess is the updelay parameter but it's a guess. Anybody else run into a problem mounting nfs on boot?

You're comparing two different products, saying they have the same advertised specs, so they must be interchangeable. That's not always the case. For example, I know with some motherboards, the density of the modules matters. Crucial's Memory Finder claims the Inspiron 5100 is limited to 512 MB modules: http://www.crucial.com/store/listparts.aspx?model=Inspiron+5100+Series According to Dell's own product specifications, the Inspiron 5100 is limited to 1 GB max system memory: http://support.dell.com/support/edocs/systems/ins5100/en/i5100-om.pdf You're looking at a support forum, and finding some information from people who managed to get it to work. The problem with that is that the spec's say what you're trying to do *won't work*. So according to all the authoritative information, what's happening is exactly what should happen. This is the problem when one exceeds the area of the supported and well-defined. You pays your money and you takes your chance. I suspect you're SOL. NewEgg has a very strict return policy. If something is defective, they'll get you a new one, but if you bought the wrong thing, that's your problem. If I'm at all unsure about a purchase, I always go through a reseller with a more liberal return policy. It usually costs about 10% more, but I'm getting something for that. Then again, you paid $16 for a RAM module; at that price, it's almost disposable. :-) Dell's support site gives no information about the upgrade of the BIOS. If I go to pull up the BIOS downloads for an Insiron 5100, I get offered a .EXE and a text file. The text file contains revision history going back to A20, which is labeled Initial release. No mention of RAM or memory is made. You state you updated from A06, which obviously contradicts the release notes. Is it possible you have some other model of laptop? For example, I know Dell had both an Inspiron 5000 and an Inspiron 5000e; despite the similar names they had very different internals. Since I don't have Windows on this machine, I used an ISO found online for the BIOS rather than Dell's .exe installer. Where did you find this ISO? From a trusted site, like Dell's Linux site? Or some random website? There's a lot of malware out there; I'd be careful if I were you. Linux's much-talked about better security won't help you if you willingly boot someone's malware on your machine. I could retry installing the BIOS - either by using a Windows XP boot CD or actually installing Windows to a partition. Windows NT install CDs are only good for installing Windows NT. (Windows XP is Windows NT version 5.1.) Unlike most Linux distro install CDs, they can't run arbitrary programs. The Dell .EXE BIOS updater says it can run from an MS-DOS boot floppy. If you don't have one, let me know; I'm sure I can find a legit disk and just give it to you for free. Not much call for Windows 95 these days. (Windows 95 (which is still the classic Windows product) still booted and ran on top of MS-DOS. So their install CDs are useful for running arbitrary MS-DOS programs.) -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

He said the rsync ran at full speed for about 30 seconds and then basically dropped to about ten percent performance after that. That sounds like Comcast's Speed Boost feature. Basically, they give you a burst of higher bandwidth for 30 seconds when you first start pulling packets, and then clamp back to nominal rate. After some inactivity (5 seconds?), they reset for the next burst. This makes web browsing go a lot faster, since web browsing is very bursty (Click, load, read. Click, load, read.). Obviously, it's not useful for bulk data transfers. Unlike, say, their TCP-port-blocking or torrent-thorttling activities, Comcast is pretty up-front about this feature. They even advertise it heavily on TV. If you want to sustain a large file transfer at steady rate, use something that limits your file transfer to the nominal rate (not the burst rate). You'll get a slower initial rate, but it won't plunge after 30 seconds. Also, make sure your send rate is limited to the upload speed of the Comcast feed. Since the feed is asymmetric, it can pull data in faster than it can send it out. That can lead to congestion, which leads to dropped packets, which leads to TCP back-off, which causes your transfer rate graph to look like a bandsaw blade. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: How to troubleshoot wide area network performance problem?
I've had suggestions from at least two colleagues that we may be the victims of peer to peer throttling. I'm going back to the Nashua site later today and I'm going to replace a small internal router that used to replace a failed router Monday. I don't believe the internal router has any bearing on the problem because the customer noticed the problem when there was no internal router in place (we bypassed it as a workaround). I'm not sure if there is any kind of tool that can be used to check for throttling. One of my colleagues ran into a Comcast throttling problem while doing an rsync at a different location. He said the rsync ran at full speed for about 30 seconds and then basically dropped to about ten percent performance after that. I need to see if something similar is going on at the Bedford site. -Alex P.S. I'll probably put in a call to One Communications today to have them check the connection/routing. Replacing the router at the Bedford site had no effect (as expected). I called One Communications and talked to an engineer who was more than willing to help. He said they use an application called hyper-trace. He was checking the connection at the Bedford end and concluded that there wasn't anything obviously wrong. He then started checking towards the Nashua end and said there's something strange. He then went on to say that the Comcast end had too many hops. So I think we're back looking at Comcast. He gave me his name and a trouble ticket number and said he'd be more than happy to assist the Comcast folks should they need to talk to him. While he was testing we were chatting and he mentioned that although his wife really likes Macs he ran an Ubuntu system. Nice to know that the folks responsible for networks are also open source enthusiasts. -Alex P.S. Since I also have less than wonderful performance from my Comcast service to the Comcast service in Nashua I might just call up and complain as an actual direct customer rather than on behalf of my clients. I'm also getting pretty irritated about this whole mess and the amount of time I've wasted troubleshooting it. I think I'm going to call MV Monday morning and see if they can provision a DSL connection at the Nashua end.

How to troubleshoot wide area network performance problem?
I have clients with an interesting network problem. One location in Bedford New Hampshire using a fractionated T1 has routinely been transmitting studies to an office in Nashua New Hampshire. There have been no problems with this for at least 18 months. However recently (about a week ago), the transmissions suddenly became slow, really slow. A transmission that was taking around 10 minutes suddenly jumped to 2-3 hours. The customer in Bedford New Hampshire is using One Communications. So far I haven't asked them to look at this problem because I've been trying to clarify it. The office in Nashua has Comcast business class service with a static IP address. Here's where it gets interesting. I had the Bedford client transmit the data to my system in Manchester New Hampshire. I have Comcast residential service. The data usually takes about 8 minutes to arrive at my location. I then send the data to the Nashua office and it typically takes 25-30 minutes. The payload is a collection of images that are typically between 65 and 70 MB. Today Comcast at the request of the customer sent someone on site to the Nashua site. The tech did some speed tests using the DSLReports Speakeasy test suite. He was getting 20 mbs down, 3+ mbs up which is pretty decent. For the fun of it I had him download a 47 MB antivirus program. His first try was ridiculous telling him it was going to take 4 + hours. I had him break the connection and try again and this time the download took around a minute. And it gets more interesting...another client in Salem New Hampshire needed to send their data to the Nashua site (they use Verizon DSL). It arrived in about 8 minutes. So my Comcast connection which is fairly decent is taking a half hour to send 65-70 MB to the Nashua site. The Salem site is taking 8 minutes for something approximately the same size and the Bedford site is taking several hours. Traceroute doesn't show much interesting - it craps out after the first 5 hops. Pinging (standard payload) from my office to the Nashua site is averaging less than 20 ms. One odd thing is that when I'm in the process of sending data to the Nashua site my pings jump up to 650 - 800 ms. The Comcast tech was happy to conclude that the Nashua site was working properly. They checked transmission levels, noise and of course the guy downloaded some files and ran the Speakeasy speed tests and all of that looked good. Any ideas how to proceed on a problem like this? Currently I'm having the customer transmit their data to me and then I re-transmit because my connection although slow is probably 4 or 5 times faster than theirs. -Alex ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

The download performance and speed tests were run with the Netgear router in place (all good). I disconnected the router from the cable modem and hooked the Mac that runs the client application directly to the cable modem. Again all download tests look normal. I replaced the original Mac with a newer model. The old system was a Mac Mini with 1 GB of Ram and a G4 CPU. The replacement model was a dual core Intel based Mini with 2 GB of Ram. The new system is definitely snappier but doesn't affect the problem at all. -Alex ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I'd like to also point out another feature of Postfix that some of you might also not be familiar with. Notice the hash: above in the transport_maps = hash:/etc/postfix/transport line. If you compile Postfix with the -DHAS_MYSQL option, then you can replace this with mysql: and the filename after the : is the location of a specially-formatted .cf file that tells postfix to connect to a mysql table and where to get the information that it wants. Postfix uses a database-abstraction model for maintaining most of these mappings in the system. Pretty much any configuration option that accepts such a parameter can be turned into a MySQL table. This greatly increases your ability to perform dynamic run-time configuration changes at will (without restarting postfix).

I know Qmail hasn't accepted outside code. I don't think Sendmail has. Does Postfix? Does Exim? Does any MTA have multiple authors? I believe that postfix is still maintained by the original author, although he does accept patches for review and inclusion. Exim is maintained by a group at the University of Cambridge (UK), though I don't know how central the project's structure is regarding the main author. I really do have to say that my favorite all-time mailserver has been qmail. The one thing qmail lacks is many of the more complex and regular features that are common with systems like Postfix, Exim, and Sendmail, as well as integration with heavier-weight IMAP back-ends. There is a large amount of qmail-specific software out there, and I found qmail's code to be wonderful to hack on when I needed to add extra features (such as editing qmail-smtpd to do more stuff at the SMTP-end). I haven't found a mailserver that scales better than qmail either for handling gigantic amounts of email flow. That said, finding others with the breadth of knowledge that I have on qmail proves quite difficult. For our IT clients, we just use Postfix because it is something that everyone can administer (hooray pragmatism). At previous job, I hosted all client mail (for 30k+ domains) through two machines using one as the mail-store (w/ courier-imap) and one as the front-end filter/remailer (for email forward accounts).

Re: Solved: Sendmail question. Problem with yahoo.
the 1st internet worm in 1988 was enabled because of the root access backdoor written into Sendmail. If I remember correctly, that back door was only available when Sendmail was run in debug mode. I seem to remember this because a friend of mine, Henry no relation Hall, was going to join us for dinner at the Hacienda Mexican restaurant on Daniel Webster Highway in Nashua with a bunch of other Digital people. Then I heard on the car radio about this worm that was attacking systems. I gleaned enough from the radio broadcast (an oddity in itself) to relay this to Henry, who instead of coming to dinner made sure that the gateway email servers in Digital were running Sendmail with debug mode turned offkeeping Digital from being affected. Unfortunately for most Unix systems, distributing and running Sendmail in debug mode was much more the practice of the day in 1984. md -- Jon maddog Hall Executive Director Linux International(R) email: [EMAIL PROTECTED] 80 Amherst St. Voice: +1.603.672.4557 Amherst, N.H. 03031-3032 U.S.A.

The majority of vehicles on the road are cars, yet both pickup trucks and tractor/trailers are more flexible. With great flexibility comes great complexity. 99.999% of the flexibility in sendmail is unnecessary for %99.999 of the sites requiring the suse of an MTA. I don't, nor do most people I know, need the ability to gateway between the Internet, ARPANet, or UUCP. Postfix has, as far as I know, a good majority of the flexibility of sendmail at a fraction of the cost in terms of readability and maintainability. Sendmail is still (and probably will be for as long as Eric Allman is alive/maintaining it) the work-horse of the internet. If I need speed and throughput, I'd still choose sendmail. If I need massive scalability, I'll choose sendmail. If I need to deal with wacky and bizarre, I'll probably choose sendmail. If I need simplicity, readability, ease of maintenance, and basic configuration, I'll go with Postfix. I know them both equally as well (which is to say, neither as well as I ought to, both farm more than want to), and in general, I prefer postfix.

I don't have a ton of Postfix experience, but using this Postfix FAQ question ( http://www.postfix.org/faq.html#incoming ) as a template of sorts (and reading bits from the O'Reilly postfix book and the postfix man pages. You would create a transport map file, say /etc/postfix/transport. Add entries for the domains you want to limit and assign them to a transport name, let's say lamdomains yahoo.com lamedomains: You need to then run: postmap /etc/postfix/transport Then in the postfix main.cf, add lines to tell it about the transport and to tell it that anything in that transport has the recipient limit. transport_maps = hash:/etc/postfix/transport lamedomains_destination_recipient_limit = 5 So now you've created a transport, put some domains in it, changed the default behavior of postfix for that transport, you just need to tell postfix what to do with that transport (aka, deliver it with smtp). Add a line to master.cf: lamedomains unix - - - - - smtp Now tell postfix to reload it's config: postfix reload Again, I haven't tested this, so you mean need to read man pages and play with that a little, but that should set a postfix user in the right direction -Shawn ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Every device reports a vendor ID, and a device ID (PCI) or product ID (USB). The tools are informed by a large database of known ID numbers. Without that database, you get only eight bytes of numeric ID. (Incidentally, MS Windows works the same way, except it builds that number-to-name database by scanning those *.INF files.) Exactly what you can do when matching depends on the tool you're using. For example, on my Fedora 6 box at home, there is /etc/udev/ and a bunch of files under it. The syntax looks pretty powerful in general. It can match by driver, kernel bus ID, sysfs attributes, etc. I haven't played with it much myself. The udev(7) man page documents some of it. I say some of it because a lot of it appears to be driven not by udev itself, but sysfs, and I haven't found TFM for that yet. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Assuming the devices are actually different USB devices (and not two units of identical models), you should be able to use the device naming facilities on your system to set-up useful aliases, like /dev/fp and /dev/spm. Basically, you create pattern matches on manufacturer/model, and assign names to the match. Depending on kernel version, distribution, etc., you will want to look in /etc/udev/, /etc/usb/, /etc/hotplug, and/or /etc/hotplug.d/. The files are usually well commented.

USB automounting problem-resolved
Awhile back I posted about a problem I had with automounting my USB drive. Using Debian Sid and Gnome. Turns out that the gparted program wrote a policy file prohibiting automounting in /usr/share/hal/fdi/policy/ when started and did not delete it when closed so it prevented automounting till deleted. Not easy to discover cause of problem. So for future reference, always check that directory as well as /etc/hal/fid/policy/ is something goes amiss to see if a policy file has gone bonkers. -- Ed Lawson Ham Callsign: K1VP PGP Key ID: 1591EAD3 PGP Key Fingerprint: 79A1 CDC3 EF3D 7F93 1D28 2D42 58E4 2287 1591 EAD3 ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Hey! I found an interesting and possibly useful file!
/etc/lvm/backup/VolGroup00 contains the same stuff as the above archives
PLUS this useful bit (pruned to keep things smaller)

device = /dev/sda2# Hint only
status = [ALLOCATABLE]

pe_start = 384
pe_count = 4372 # 136.625 Gigabytes
}
pv1 {
id = oACqnk-YQTQ-IiGy-F6Pj-UoBB-kUqM-g6Yu3D
device = /dev/sdb # Hint only
status = [ALLOCATABLE]
dev_size = 286746624# 136.731 Gigabytes
pe_start = 384
pe_count = 4375 # 136.719 Gigabytes
}
}
Whoo hoo! There's my bogus uuid. I'm thinking that I should be able to
re-create things with this information.

Make sure you have full backups of everything, reinstall Linux, and restore your files from backups. Take off and nuke the site from orbit. It's the only way to be sure. I suspect they're more afraid of the unknowns. The current system is a bit of a question mark. A total reload will provide assurance the system config is intact and known. That's the safer route in their book. Of course, they're not the ones who have to rebuild the system :-( Here is the output of various display commands: Which all seem to indicate that the volume group named VolGroup00 is not working. You did say this system was running, right? I'm wondering just how screwed up things are. If what LVM is reporting is right, there shouldn't be a system to run... Have you rebooted since the borkage occurred? If not, I suggest avoiding doing so. The system may not come back up. I'm especially worried that you have holes in your LVs that you just haven't run into yet. If you have backups from before the borkage, I'd pull the media out of the rotation pool, and keep them indefinitely, in case you discover trouble later. At some point, once you're out of the woods, and after making new backups, I'd suggest scheduling downtime for an fsck, and/or a database or other application-level consistency check. I know downtime can be hard to come by, but... better to run the checks at 4 AM on a Sunday than 1:32 PM on a Thursday after the system crashes. You will note that nowhere in there is any mention of the problematic uuid. Also there is no mention of the physical volume sdb, only of sda2. That may or may not be a good thing. It all hinges on whether any extents from the PV that was on sdb got allocated to any LVs at some point. If the LVs have extents mapped to the damaged PV on sdb, then restoring the metadata of the damaged PV is what you want. If the LVs exist entirely on the PV on sda2, you may be better off restoring the VolGroup00 metadata from before the trouble happened. Then just start over -- create the PV on sda2 as if none of this ever happened. Normally, lvdisplay -m will show you the LE-to-PE mapping. But according to the lvdisplay -v you posted, there isn't any such mapping. At all. Try the --partial switch to the various LVM commands. According to the man page, it will not allow modification of metadata, so it should be safe. There are also some words in there about re-creating a missing PV and restoring LVM config that you may want to read. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
