Status line for text mode console
Some question, inspired by my mainframe time... Is there a port that allows FreeBSD to be equipped with some kind of status line when using the shell on a text mode console? With status line I mean some automagically updating text line that informs about... date, time, terminal, actual system load, number of users logged in or another status, for example like this: [EMAIL PROTECTED]:~/src/bla% _ --- [EMAIL PROTECTED]:ttyv2 (3) .:I = =2008-11-30 07:02:15 For example, the status line sits in line 25, line 24 contains a barrier, and the shell runs on lines 1 - 23.

There are some special situations where PF shines though, Asherons Call (or any other game using bidirectional UDP traffic) can be made to work with following configuration: This to nat section: binat on $ext_if from my internal gaming IP to game server netblock or IP - $ext_if Which should do the trick with some of the silly games out there using standard defined, but really rare kind of traffic. -Reko ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Setting a different default source address
Is it possible to set a default source address on a machine? I have an ADSL connection with a fixed IP and a further /29 routed to it. Until recently I used an ADSL router which acquired the connection IP, and then the first of the /29 on the internal interface. In an effort to conserve both IPs and the number of machines I have running I have recently changed to using an ADSL modem (Vigor Draytek 110) which essentially does no more than change the PPPoA to PPPoE. A FreeBSD machine then handles the connection using ppp. The machine in question has always used one of the /29 addresses, and continues to do so (this is assigned to its DMZ facing NIC, vr0). Now, of course, outgoing packets are using the connection address, which is assigned to tun0. Whilst I can override this on an application by application basis for many things (eg postfix smtp_bind_address parameter, ping -S switch) is there any way to override it system wide, so that the address from the /29 is used by default? I think I succeeded in doing something similar for an IPv6 tunnel by not assigning an IP address to gif0 and configuring the routing as follows in rc.conf: ipv6_defaultrouter=-interface gif0 But I'm not clear whether this would work with ppp, and if so, how to do it. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You need to keep something in mind here: Marvell does not give out documentation for their cards publicly, so Yong-Hyeon has to reverse-engineer and tinker with what he already knows. Some hardware feature do not work, others are buggy, others work fine on specific revisions of the chip while later ones break. And if you tell me Well Linux has support for this chip!, I will throw the following evidence back in your face: Marvell and other companies are giving Linux developers development PCI cards to develop drivers with (sometimes even before the card is out in the market), so Linux has the upper hand here. They are not doing this with the BSDs. Purely as an example: in my Wiki, section Network devices, see the entry for the 88E8040 NIC. I'm still working with Yong-Hyeon to try to get him access to a laptop that has this chip so he can write the driver. http://wiki.freebsd.org/JeremyChadwick/Commonly_reported_issues This should give you some idea of the complexities.

My understanding is that a GPT requires the MBR to be a PMBR (only one partition in the 4th slot with a special type of 0xee that covers the whole disk). What this box is doing is trying to make the MBR match the first 4 partitions in the GPT. I'm not sure if you will be able to get FreeBSD's GPT stuff to recognize that reliably. Marcel (cc'd) might have some ideas. If you can get FreeBSD's GPT support to handle this disk it will mean that you will have to use only GPT device names (so /dev/ad0p4a instead of /dev/ad0s4a). You will also need to make sure the GPT partition for FreeBSD has the right UUID since your partition contains a BSD label.

Some hardware feature do not work, others are buggy, others work fine on specific revisions of the chip while later ones break. Don't get me wrong - I appreciate that people are working in the trenches on this stuff and thats great about FreeBSD. I only switched to the Marvel .ko as it was suggested on previous questions list, so didnt spend much time with the stock 7.0 driver. And if you tell me Well Linux has support for this chip!, I will throw the following evidence back in your face: Marvell and other companies are giving Linux developers development PCI cards to develop drivers with (sometimes even before the card is out in the market), so Linux has the upper hand here. They are not doing this with the BSDs. I guess even specs would be nice - hardware donations would be nicer though :) I would urge you to go out and purchase an Intel Pro/1000 PT card Funnily enough, in the back of my mind I had the same thought upon seeing the words 'Marvell' amongst the mobo spec. Thats said at least they made an effort on supporting multi OS http://www.marvell.com/drivers/search.do even if they are a precious with their specs etc With some Vendors its Windos or nothing. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

But being an infrequent participate of OSS I don't know how to contribute this information back to the author / maintainer of the manual (not mentioned in the manual itself). I also worry improving something that hasn't been changed for 10 years could be difficult because nobody wish to move them. What should I do or who should I contact to let them decide if they include my idea in their manual as well? In fact I think the 4th lottery idea isn't better than any of 5, 6, 7 because it is not a full use of strfile, which can produce random text repeatedly (in case of 4, random text is only needed as many time as you decide to give price to someone).

Re: GPT Support on Freebsd
On Oct 30, 2008, at 6:36 AM, John Baldwin wrote: Ok, so it's not a PMBR. My understanding is that a GPT requires the MBR to be a PMBR (only one partition in the 4th slot with a special type of 0xee that covers the whole disk). What this box is doing is trying to make the MBR match the first 4 partitions in the GPT. I'm not sure if you will be able to get FreeBSD's GPT stuff to recognize that reliably. Marcel (cc'd) might have some ideas. In FreeBSD 6, the kernel checks explicitly for a PMBR when it checks for a GPT. Besides being part of the specification, it also avoids conflicts. In the GEOM framework, there's no a priori support for having one GEOM control another. When there's a valid MBR as well as a valid GPT, it's undeterministic which one will be used, unless they both cooperate. They don't. This is where GPart helps out. In FreeBSD 7 and up, GPart supports multiple partitioning schemes, including MBR and GPT. The kernel will not enforce a PMBR in front of a GPT, because upon detecting both a MBR and a GPT, the GPT will be used. However, this only applies when the kernel is configured with GEOM_PART_MBR and not with GEOM_MBR. At this time GEOM_MBR is still the default. So, to make it work for you, you need at least FreeBSD 7.1 (to be released shortly) or use next month's snapshot and build a custom kernel without GEOM_MBR and with GEOM_PART_MBR. In FreeBSD 8 and up GPart is the default and you won't have to make a custom kernel in that case.

Read his statement once more: For example, I load up a client (game) and it connects out on XYZ port. The server will send data back on ABC. I assume based on this, the following is happening: - 192.168.x.x:a sends packet to gameserver:xyz - NAT gateway translates packet (where natgw is a public WAN IP) 192.168.x.x:a -- natgw:b -- gameserver:xyz - gameserver sees packet to port xyz, and initiates new connection to natgw:abc - NAT gateway drops packet destined to WAN IP port abc, because the gameserver:abc connection is *new*, and does not relate to the previous NAT'd gameserver:xyz connection. If this is **truly** how the protocol works (the OP will need to be absolutely 100% positive of that fact; I recommend he reconfirm how it works), then the only solution is to set up a port forward on the NAT gateway for port abc to point to 192.168.x.x. This also means that only one computer on the LAN will be capable of playing this game. Not much one can do about that, other than write the authors of the game and explain that their protocol is absolutely disgusting. Does the game support IPv6? This may be a work-around for you, since you can get a relatively large chunk of IPs for free via any one of a number of tunnel brokers. If possible, ask your IP provider if they provide native IPv6 transport first. A few do, in North America and Europe, and a surprising lot do in Asia, especially Japan and South Korea. If you're on a North American consumer ISP, chances are a tunnel broker is your only option for v6 connectivity, however. If the game doesn't support IPv6, however, then you are likely stuck with playing with port forwarding from the public routable address, however. It stinks, so feel free to lobby your ISP, the game's designers, and any other involved parties, about supporting IPv6 connectivity. In essence, a problem like the one Mr. Chadwick is eluding to is one of the primary motivating forces behind the adoption of IPv6 to begin with. - mdh ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

If you have additions to this please post a followup to this thread, keeping the Cc: (I'm not on -questions...) 1. You need RELENG_7 from at least Mon Oct 20 11:15:57 2008 UTC (the relevant MFC commits are: http://svn.freebsd.org/viewvc/base?view=revisionrevision=183819 http://svn.freebsd.org/viewvc/base?view=revisionrevision=184075 - a recent HEAD should also work of course.) There are linprocfs patches for RELENG_6 too (merging the former commit), but the latter commit can't be merged to 6 (and 7.0) since they lack the cpuset bits, so flash9 probably won't work on SMP there. (Although if you have SMP you probably should be running 7 anyway. :) Oh and if you do have SMP you also need to use the ULE scheduler, the cpuset syscalls are not supported with 4BSD. linprocfs patches for 6: http://people.freebsd.org/~nox/linprocfs-6.3.patch http://people.freebsd.org/~nox/linprocfs-6.4.patch 2.

Make sure linprocfs is mounted to /compat/linux/proc . 4. Make sure www/nspluginwrapper, www/linux-flashplugin9 and dependencies are installed and up to date(!). (the default emulators/linux_base-fc4 should work, if you want to use a later one don't forget to set compat.linux.osrelease=2.6.16 in sysctl.conf and OVERRIDE_LINUX_BASE_PORT to whichever version you use in make.conf. Note however that on 6, only the default compat.linux.osrelease=2.4.2 really works.) 5. If the plugin doesnt show up in firefox' about:plugins, run nspluginwrapper -i /usr/local/lib/npapi/linux-flashplugin/libflashplayer.so and restart firefox. 6. And remember there's a security advisory for the current version of flash9, http://www.FreeBSD.org/ports/portaudit/78f456fd-9c87-11dd-a55e-00163e16.html (if you use portaudit you need to `make -DDISABLE_VULNERABILITIES ...' to be able to install the port), and fc4 seems to be eol'd too, so you probably want to install something like the noscript firefox extension, https://addons.mozilla.org/en-US/firefox/addon/722 and only allow plugins (and scripts, tho thats a different problem) on sites you trust... And finally, if you still get crashes after following the above even on pages that are reported to work now (like youtube) you probably want to run `ktrace -di firefox...' and look at the output using linux_kdump (thats the devel/linux_kdump port, you want to use a package), paying specific attention to the lines above `PSIG SIGSEGV' (or whichever signal you got), maybe there are still shlibs missing that the plugin needs (NAMI ...something.so...), and if this is the case tell us about it so the appropriate dependencies can be added to the relevant ports. If you can't figure it out I guess it doesn't hurt to post the last few 100 lines of the dump up to the relevant PSIG on -emulation... You may also want to check linked shlibs like this: /compat/linux/bin/sh /compat/linux/usr/bin/ldd /usr/local/lib/npapi/linux-flashplugin/libflashplayer.so and /compat/linux/bin/sh /compat/linux/usr/bin/ldd /usr/local/lib/nspluginwrapper/i386/linux/npviewer.bin (if you see `not found' in there you know something is wrong) - although that doesn't show libs that may be dlopen()d at runtime. Thanks for this. I was able to get linux-flashplugin9 working in native Firefox 3.0.3 on FreeBSD 7-STABLE i386. The only additional thing I had to do was copy /usr/X11R6/lib/browser_plugins/npwrapper.libflashplayer.so into ~/.mozilla/plugins/ for Firefox to recognize the plugin. Yeah I forgot to note that you want to run nspluginwrapper -i as the user that will run the native browser, not as root, then the wrapper will go into ~/.mozilla/plugins/... After that Youtube, google video, and google maps (incl. street view) work fine, but slow.

Re: Firewalls in FreeBSD?
Ok, I had some progress with this last night. Basically what I do is:
in natd - redirect_port 1000 to 1 to the internal windows box.
set ipfw to open file wall.
Obviously this isn't prefect - but gives some idea of what's going on.
What I'd like to do, is a) keep the nat redirects since that works
pretty well.
b) in ipfw, ONLY allow data back on these ports IF the windows box has
established the connection out first then deny everything else.
I tried this, but it didn't work for anything (tried 5-6 differant games):
${fwcmd} add allow tcp from any to any out via x10 setup keep-state
${fwcmd} add allow udp from any to any out via xl0 keep-state
${fwcmd} add allow icmp from any to any out via xl0 keep-state
${fwcmd} add 100 check-state

Are you sure about that? Read his statement once more:
For example, I load up a client (game) and it
connects out on XYZ
port. The server will send data back on ABC.
I assume based on this, the following is happening:
- 192.168.x.x:a sends packet to gameserver:xyz
- NAT gateway translates packet (where natgw is
a public WAN IP)
192.168.x.x:a -- natgw:b --
gameserver:xyz
- gameserver sees packet to port xyz, and initiates new
connection
to natgw:abc
- NAT gateway drops packet destined to WAN IP port abc,
because the
gameserver:abc connection is *new*, and does not relate
to the
previous NAT'd gameserver:xyz connection.
If this is **truly** how the protocol works (the OP will
need to be
absolutely 100% positive of that fact; I recommend he
reconfirm how it
works), then the only solution is to set up a port forward
on the NAT
gateway for port abc to point to 192.168.x.x.
This also means that only one computer on the LAN will be
capable of
playing this game. Not much one can do about that, other
than write
the authors of the game and explain that their protocol is
absolutely
disgusting.
Does the game support IPv6? This may be a work-around for you, since you can get a relatively large chunk of IPs for free via any one of a number of tunnel brokers. If possible, ask your IP provider if they provide native IPv6 transport first. A few do, in North America and Europe, and a surprising lot do in Asia, especially Japan and South Korea. If you're on a North American consumer ISP, chances are a tunnel broker is your only option for v6 connectivity, however.
If the game doesn't support IPv6, however, then you are likely stuck with playing with port forwarding from the public routable address, however. It stinks, so feel free to lobby your ISP, the game's designers, and any other involved parties, about supporting IPv6 connectivity.
In essence, a problem like the one Mr. Chadwick is eluding to is one of the primary motivating forces behind the adoption of IPv6 to begin with.

And let's not forget that the OS/kernel is also gone, which means any writes which were sitting in cached memory in the kernel are lost as well. Even disabling write caching on the disks themselves won't help, although it might help with actual I/O performance (using 2 levels of caching: RAID controller, and OS/kernel). In this scenario, write caching on the disks is usually done by the controller itself (through a BIOS option), and not by FreeBSD.

RE: Large discrepancy in reported disk usage on USR partition
I took a look at using the smart tools as you suggested, but have now found that the disk in question is a RAID1 set on a DELL PERC 3/Di controller and smartctl does not appear to be the correct tool to access the SMART data for the individual disks. After a little research, I have found the aaccli tool and used it to get the following information: Sadly, that controller does not show you SMART attributes. This is one of the biggest problems with the majority (but not all) of hardware RAID controllers -- they give you no access to disk-level things like SMART. FreeBSD has support for such (using CAM's pass(4)), but the driver has to support/use it, *and* the card firmware has to support it. At present, Areca, 3Ware, and Promise controllers support such; HighPoint might, but I haven't confirmed it. Adaptec does not. What you showed tells me nothing about SMART, other than the remote possibility its basing some of its decisions on the general SMART health status, which means jack squat.

If this is a production environment, step back a moment and ask yourself: just how much time is this worth? It might be better to just newfs the filesystem and be done with it, especially if this is a one-time-never-seen-before thing. I will wait and see if any other list member has any suggestions for me to try, but I am now leaning toward scrubbing the system. Oh well. When you say scrubbing, are you referring to actually formatting/wiping the system, or are you referring to disk scrubbing? I meant reformatting and reinstalling, as a way to escape the issue without spending too much more time on it. I would of course like to understand the problem so as to know what to avoid in the future, but as you make the point above, time is money and it is rapidly approaching the point where it isn't worth any more effort.

Is this what you mean by avoiding Hardware Raid? More or less. Hardware RAID has some advantages (I can dig up a mail of mine long ago outlining what the advantages were), but a lot of the time the controller acts as more of a hindrance than a benefit. I personally feel the negatives outweigh the positives, but each person has different needs and requirements. There are some controllers which work very well and provide great degrees of insights (at a disk level) under FreeBSD, and those are often what I recommend if someone wants to go that route. I make it sound like I'm the authoritative voice for what a person should or should not buy -- I'm not. I predominantly rely on Intel ICHx on-board controllers with SATA disks, because ICHx works quite well under FreeBSD (especially with AHCI). I personally have no experience with gmirror or gvinum, but I do have experience with ZFS. (I'll have a little more experience with gmirror once I have the time to test some reported problems with gmirror and high interrupt counts when a disk is hot-swapped). I hope these are SCSI disks you're showing here, otherwise I'm not sure how the controller is able to get the primary defect count of a SATA or SAS disk. So, assuming the numbers shown are accurate, then yes, I don't think there's any disk-level problem. Yes, they are SCSI disks.

Specifically with regards to SMART: historically, SCSI does not provide the amount of granularity/detail with attributes as ATA/SATA does. I do not consider this a negative against SCSI (in case, I very much like SCSI). SAS might provide these details, but I don't know, as I don't have any SAS disks. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making

I then tried using Marvells own driver the website [myk] and the results where about the same. Just before I was about to give up and put in my trusty old 3Com 3C509 [xl] I noticed that in the Marvell doco there where several tunable params so decided to try out a few.

I'm not sure you suffers from the same problem but there was a Tx checksum offload related bug in msk(4) driver and it was fixed in HEAD.

I've CC'd him on this mail; he usually hangs out on -stable though. You need to keep something in mind here: Marvell does not give out documentation for their cards publicly, so Yong-Hyeon has to reverse-engineer and tinker with what he already knows. Some hardware feature do not work, others are buggy, others work fine on specific revisions of the chip while later ones break. And if you tell me Well Linux has support for this chip!, I will throw the following evidence back in your face: Marvell and other companies are giving Linux developers development PCI cards to develop drivers with (sometimes even before the card is out in the market), so Linux has the upper hand here. They are not doing this with the BSDs. Purely as an example: in my Wiki, section Network devices, see the entry for the 88E8040 NIC. I'm still working with Yong-Hyeon to try to get him access to a laptop that has this chip so he can write the driver. http://wiki.freebsd.org/JeremyChadwick/Commonly_reported_issues This should give you some idea of the complexities. As I said, Linux has the upper hand, because they're getting support from Marvell. It seems that hw cs is on by default so I added the above to my ifoncfig line in /etc/rc.conf and now all is snappy! I was wondering how could this be the case and also if anyone else had this issue with Marvell chips? I would urge you to go out and purchase an Intel Pro/1000 PT card, which runs for around 30-40 USD.

It does not disable card features. I mean, the individual disks are invisible to the OS unless the card's driver (and the card itself) specifically supports it. Correct. With regards to ATA: ata(4) has support for pass-through on some RAID cards, such as Promise. FreeBSD will see the individual disks (e.g. ad4, ad6, etc.) as well as the array (e.g. ar0). With regards to SCSI: pass(4) provides this capability. I don't think in the case of SCSI that the disks will appear in FreeBSD (e.g. da0) though. Instead, pass(4) can be used to query individual disks on an array, e.g. smartctl's -d flag (e.g. -d 3ware, -d marvell, etc.). In both cases (ATA and SCSI), the card itself has to support pass-through, *and* the FreeBSD driver has to have code to allow for such, otherwise no go. There's also the below PR, which extends atacontrol to permit disabling and enabling write caching on a per-disk basis. http://www.freebsd.org/cgi/query-pr.cgi?pr=127717 But not on disks which are behind hardware raid cards, correct? Correct. For FreeBSD to be able to disable write caching on disks behind a RAID controller, one of two things is needed: 1) Pass-through support (see above), 2) A native CLI program that interfaces with the card directly (usually written by the vendor). Sadly, #2 appears to be the most common choice when a RAID card is used. I say sadly because many vendors do not support FreeBSD, and only offer Linux CLI programs -- requiring an administrator to install Linux emulation, Linux libraries, etc., and *hoping* that it works. If the neither of the above options are available, then your only choice is to go into the RAID card's BIOS and disable write caching in there, assuming the option exists (on many cards it does). What gives you the impression that during a power outage your data is going to be intact? One of the main functions of softupdates is to order disk updates in such a way that the fs organizational integrity is maintained at all times. And we've recently found that this is simply not the case. The benefits of SU are applicable to very specific environments; desktop PCs are the main ones, offering great performance improvements there. But there's a known problem with the background fsck feature of FreeBSD, which is only applicable to filesystems which use SU; sometimes fsck does not correct all errors, causing the filesystem to be marked clean, even though there are actual problems with it. There's a thread from about a month ago discussing why background_fsck=no is highly recommended when using SU. Of course this doesn't protect against actual sector corruption, but if the disk is between writes at the time it loses power, the fs structure is supposed to still be internally consistent. At least that's my understanding of it. Yep, that's how I understand it as well. But this is a different topic than what we were discussing 2-3 replies ago, talking about how a RAID controller with cache + BBU is sufficient enough to guarantee data integrity even when power is lost -- that's incorrect. Back to write caching: Disabling write caching on disks does not guarantee integrity in the case of such failures either -- on the other hand, by disabling an extra layer of caching, you've essentially diminished the risk by only a nominal amount. I personally believe disabling write caching is not a plausible option for users; the performance hit is major (I have done tests) -- write speeds drop to 12% of total capability. Meaning: 70MB/sec with WC enabled, 8.4MB/sec with WC disabled. This is *without* a controller that does caching of any kind. Essentially you can use this to benchmark which is faster: write caching disabled on disks + caching enabled on a controller, or write caching enabled on disks + caching disabled on a controller. It would be interesting to see benchmark comparisons of different controllers. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

Is df really df or an alias to 'df -t nonfs'? Yes, it really is the untruncated output of df -h. I also tried the df -t nonfs and it gives exactly the same output as df. What are you expecting that is not present in the output ? Is it possible that nfs directory got written to /usr at some point in time? You would only notice this with du if the nfs directory is unmounted. Unmount it and ls -al /usr/mountpoint should only give you an empty dir Bingo!! That is exactly the problem. An NFS mount was hiding a 17G local dir which had an old copy of the entire NFS mounted dir. I guess it must have been written incorrectly to this standby server by RSYNC before the NFS mount was put in place. I will add an exclusion to rsync to make sure it does not happen again even if the NFS dir is not mounted. Thank you for your help, you have saved me much time rebuilding this server. Can either of you outline what exactly happened here? I'm trying to figure out how an NFS mount was hiding a 17G local dir, when there's no NFS mounts shown in the above df output. This is purely an ignorant question on my part, but I'm not able to piece together what happened. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

Much too complicated. :-) I'm using screen on a daily basis to manage
multiple SSH sessions (very comfortable tool), but for something that
should run locally (a local terminal session) it doesn't seem to be
the right tool.
That's right, but screen(1) is pretty easy to configure this way. You
just have to add a `.screenrc' file with:
caption always %{= bf}%5n %t (%H) %l%=%Y-%m-%d %c:%s
This should produce a colored, blue 'hardstatus' line near the bottom of
the screen window, that displays something like this:

FWIW, I regularly use screen(1) in console sessions too, because ssh
sessions to `other' OS types work much better with a terminal type of
`screen'. Some Linux and Solaris systems do funny things when the
environment includes `TERM=cons25' :(
