sed outputs constantly, while perl does its output at the end at once.
Try:
time awk '{print $1}' Desktop/klog > kadr3
awk also outputs at the end, however is much smaller than perl (and
therefore much quicker).

There is also NTFS through ntfs-3g ,which is available for all of the above (sysutils/fusefs-ntfs on FreeBSD).

Re: ndis0 no link on 6.3-RELEASE
Hi everyone. Sorry to bump such an old post, but I have figured out a 'hack' to get this driver to work, and figured I'd post here, in case it may help someone else. Previously, I said the following, about a Broadcom 4318 chipset on a Dell Inspiron b120: "Upon 'kldunload bcmwl5.ko; kldload bcmwl5.ko', my ndis0 card looses all WPA capabilities." The fix is as follows, as I have been unable to find anything relevant regarding netif, dhclient, wpa_supplicant or ndis: Step 1: Create /etc/rc.local, with '/sbin/kldload /boot/modules/bcmwl5_sys.ko' Step 2: Edit /etc/wpa_supplicant.conf as needed Step 3: Echo 'ifconfig_ndis0="WPA DHCP"' to /etc/rc.conf Outcome: System boots, loading netif, dhclient, and wpa_supplicant. Next, after the other three are running, the rc.local script loads the ndis0 driver. On my system (and surrounding networks) my system tries to authenticate against any available network, but then finally reads wpa_supplicant.conf, and uses my network. As I said, sorry to bump an old thread, but hopefully this will help someone else, regardless of how crude of a hack it is.

Re: OT: most "universal" file system for 1TB external USB2 hard drive
Windows XP Pro. If I want all of these systems to be able to read and write to the drive, what file system should I use? I know fat32 is pretty universal, but is it advisable? yes, just don't put too many small files on it as it's wasteful. and don't put too big files (in order of many GB) too, because it gets slow then. but yes - it's the only FS really portable. not because it's good (exactly opposite) but because it's very simple to implement and it's common, so every OS has fat16/32 support. the other solution is to use unix UFS, and install UFS driver for windoze, which exist AFAIK (at least i had this for win98 some time ago). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Well, the filesystem with the most interchange quality isn't a real file system - it's tar. Inside the UNIX world, it's very welcome if you need to exchange data from, let's say, Sun, SGI and x86 UNIX systems using a physical device. Because "Windows" is intendedly not able to access file systems that are not made by MICROS~1, UFS (which you could access from Mac OS X as well as from the BSDs) would be a good choice, but it can't be chose due to your requirements in this setting. Something like an MS-DOS filesystem would be accessible from all the systems you mentioned, but it doesn't bring you much comfort (for example no user management, no access rights). -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I've examined some of the data contained in the error
message, I inserted some "pretty printing code" to see
which condition was present at abort time:
--- condition: inumber > lastvalidinum
--- inumber=306176 lastvalidinum=306175, lastinum=306176
fsck_ffs: bad inode number 306176 to nextinode
I commented out this errx() block and found out:
--- condition: inum > maxino
--- inum=6545 maxino=6544
fsck_ffs: inoinfo: inumber 6545 out of range
It seems that some values (lastvalidinum, maxino) are retrieved
incorrectly, given the assumption that one inode is needed per
file (and directory). Conslusion: Too few of them.

Yes, fsdb is a very good tool. I did dive into the filesystem and
found out that many files are still there. I'll take some time
to learn more about UFS and fsdb. Maybe there's a way to restore
files - as I mentioned, "Windows" recovery software is able to
retrieve arbitrary files and subtrees from the dd image. So should
BSD, too.

If I found enough information, I'll ask again, with more substance
and less assumptions.

In Germany, this is called "Lehrgeld". :-) But as I found
out by calling some recovery services, they've got no big
clue about BSD file systems, their main business is FAT and
NTFS stuff, along with disassembling drives in cleanrooms.

Tools like dls, ils and fls (from The Sleuth Kit) are very
promising. Maybe they can help. Other tools that allow to
create images from defective media (e. g. ddrescue) are nice,
too, but don't help here because image retrieval has been no
problem.

It hasn't been a power loss. At some point in ordinary working,
I think I'd been surfing the Web at this time, the machine
stopped, stood still for approx. 5 seconds, then dropped to
the console /dev/ttyv0, put an error message and rebooted.
After this, fsck_ffs found many errors on /, /var and /usr
(e. g. /usr/X11R6/ had disappeared and was restored in pieces
into lost+found/), the system didn't boot anymore. So I took
another system to copy important data from the drive, which
worked for everything except _my_ home directory.
I have _no_ clue what happened... and I think all I need to
do is to have fsck_ffs iterate on all the inodes that are not
connected to my home directory anymore, or, create a new inode
that connects to all these inodes that had been the content
of my home directory. I hope there is a way to do this.

People want cheap, they get cheap. You can't imagine how I
hate this crappy cheap stuff...
Except of an power outage, there could be other things imaginable
that could leat to the destruction of an inode. Writing processes
are "more dangerous" than reading processes. BUT DID IT HAVE TO
BE _MY_ HOME DIRECTORY?! :-) Yes, it had to, because I relied to
much on the fact that FreeBSD served me well for more than 5 years
so I didn't see a neccessartity for backups ("I'll do them next
week."), and that's the revenge.

That's why I bought 2 x 500 GB WD drives to make a copy pf
everything I still have, and I put them onto the shelf.

I have an USB 2.0 carrier where I'll put an PATA disk in.
At the moment, I'm doing the backups by putting the drive
directly into the machine (ATA-100 cable).

PF traffic management on two devices + VPN
Hi,
I use PF to manage the traffic going through a VPN connection (ng0 to
ng1). I am also able to manage the traffic on the device where I
expect the VPN traffic (ed1 and ed2).
But now my problems starts I also want to manage the outgoing traffic
on ed0 to the WAN side.
On my router s Squid installed, so I thought that all packages
generated by my FreeBSD machine could be put into a queue for ed0.
If i check the settings with pftop than everything looks fine. But it
looks like the limits for the upper limit are totally ignored.
So I did a check from the other side. I installed an Apache on that
server and tried to download a file from that server. And hey there is
my bandwidth management.
So I am confused. How can I handle the traffic generated by the squid
on the router on the WAN interface?

However, there is also also a reasonable chance that it is a security breach if you are running an unsecured wireless network. What I would recommend is that you probe the unknown device with something like nmap (available from ports security/nmap) with something like nmap -O -sV IP-ADDRESS-OF-MYSTERY-DEVICE That should give you a fair amount of information about the device.

The spam filters my employer uses will discard any email arriving with our domain in the From line. So I cannot see my own mail from any listserve that keeps the originator's address as the source. There is a way to fix that, but it exempts the listserve's domain from the filters. In addition, there are too many people and listserves involved, so it is not manageable.

I've got a backup server that, every night, offloads things to a

See the developers handbook for more details on how to report panics
(you also need the backtrace, and it may help to catch the problem
earlier if you turn on debugging).
However, this kind of panic can happen if the drive is marginal. e.g.
if it loses or corrupts I/O in transit. Try compiling e.g. the
/usr/src/tools/regression/fsx tool and running that against the problem
disk for a few days, or even multiple instances on different files at
once to really stress it. It will do lots of I/O to a file and verify
that the file remains consistent throughout. It won't touch the whole
drive though, so if only parts of the disk are bad it won't catch it.
For that you could try generating a large random file on another disk,
keeping the md5 checksum, then writing lots of copies of it to the bad
disk to fill or almost fill it, then read back the md5 checksums of each
to compare. A small script could run this in a loop.
Yet another option would be to configure the disk as a geli or zfs
volume, since that will validate checksums with each read and will catch
data corruption anywhere on the disk.
I'd validate those things before proceeding with the existing panic.

You could use this script: http://www.secnetix.de/olli/scripts/bold It's a filter that works like similar to grep, but it highlights the parts that match your regular expression.

Dual booting FreeBSD and Linux using GRUB fails
I have an all-SCSI system with FreeBSD 6.3 on one disk and 7.0 on the other. It booted using GRUB and worked OK. I installed Mandriva Linux on the disk that had 7.0 on it (replacing 7.0) The setup now is: SCSI ID 15 73GB /dev/sda - running FreeBSD SCSI ID 14 36GB /dev/sdb - Mandriva The device names above are as reported by Mandriva when doing the install. Mandriva installed OK onto the 36GB HDD and wrote this menu.lst: Code: timeout 10 color black/cyan yellow/cyan gfxmenu (hd0,0)/boot/gfxmenu default 0 title linux kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=77a15e0a-b9f5-46ab-8236-886418dbbfd8 resume=/dev/sdb5 splash=silent vga=788 initrd (hd0,0)/boot/initrd.img title linux-nonfb kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=linux-nonfb root=UUID=77a15e0a-b9f5-46ab-8236-886418dbbfd8 resume=/dev/sdb5 initrd (hd0,0)/boot/initrd.img title failsafe kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=failsafe root=UUID=77a15e0a-b9f5-46ab-8236-886418dbbfd8 failsafe initrd (hd0,0)/boot/initrd.img Note that it has used hd0 even though the disk is /dev/sdb (which implies the second disk). The problem is that when it boots the Adaptec SCSI BIOS searches for bootable drives from the highest SCSI ID downwards. Since the 73GB (FreeBSD) disk is id 15 it boots from that. That disk also has GRUB installed with an entry for FreeBSD which is also hd0. The FreeBSD entry works. Because the disks are seen by the SCSI BIOS as id 15 first, id 14 second, id 14 - the disk with Mandriva installed, is hd1 so I copied the Mandriva menu.lst file into the one on the FreeBSD partition and edited hd0 to hd1 (for both the lernel and initrd lines) but Mandriva won't boot, I get Error 2: Bad File or Directory type In fact, the FreeBSD GRUB seems unable to read the Linux disk - it knows it's there, but can't access anything on it. I've tried numerous things as suggested on the Mandriva forums but nothing works: grub> root (hd0,0,a) Filesystem type is ufs2, partition type is 0xa5 grub> cat /boot/grub/device.map (fd0) /dev/fd0 (hd0) /dev/da0 (hd1) /dev/da1 grub> root (hd1,0) Filesystem type is ext2, partition type is 0x83 grub> cat /boot/grub/device.map Error 2: Bad file or directory type grub> root (hd Possible disks are: hd0 hd1 grub> root (hd1, Possible partitions are: Partition num: 0, Filesystem type is ext2fs, partition type 0x83 Partition num: 4, Filesystem type is unknown, partition type 0x82 Partition num: 5, Filesystem type is ext2fs, partition type 0x83 grub> root (hd0, Possible partitions are: Partition num: 0, [BSD sub-partitions immediately follow] BSD Partition num: 'a', Filesystem type is ufs2, partition type 0xa5 BSD Partition num: 'b', Filesystem type is unknown, partition type 0xa5 BSD Partition num: 'd', Filesystem type is ufs2, partition type 0xa5 BSD Partition num: 'e', Filesystem type is ufs2, partition type 0xa5 BSD Partition num: 'f', Filesystem type is ufs2, partition type 0xa5 Can anyone suggest how to make this work?

Re: rtprio + su - doesn't work
tu run (at startup) asterisk PBX as user centrala with realtime priority. asterisk is started, but without realtime priority. Yes, you'd be running the su process with realtime priority. :-) and su forks shell and asterisk - isn't it? how to do this right? i run asterisk as user (not root), but this server is used to other things, so asterisk must have absolute priority over other things. now i have to do this manually by searching for asterisk's PID and doing rtprio 31 -PID Well, you have to run rtprio as root, or else make it setuid-root (which probably isn't a great idea). Presumably this thing has a startup script which runs it, and it probably creates a PID file under /var/run which you could use to adjust the priority during system startup via: rtprio 31 -`cat /var/run/asterix.pid` did this /usr/bin/su centrala -c \ "/usr/local/sbin/asterisk -C /centrala/etc/asterisk.conf" /bin/sleep 5 /usr/sbin/rtprio 31 -`cat /centrala/run/asterisk.pid` works fine, but looks like workaround for me not proper solution? am i wrong? thank you for explanation why it doesn't work directly Wojtek ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: Unable to access certain sites from FreeBSD 6.2
Thanks Norberto,
Makes sense to do it the other way round. If I could indulge your generosity
and knowledge, one thing is puzzling me, why do I not have this problem when
I am running Win XP on the same machine (dual boot with FreeBSD) using all
the same hardware. Or when running NetBSD on my desktop machine but with
the same network. Seems strange that FreeBSD, which generally works really
well out of the box, cannot 'just deal' with this problem. I realise that
it is not FreeBSD's problem per se, but a badly configured router somewhere
'out there', just seems that it must be common enough for some part of the
OS to handle it without needing any tweaking. FreeBSD seems great, I am in
the process of migrating from NetBSD so am quite used to configuring as
necessary,
does FreeBSD 7 encounter this situation?
Regards,
Alasdair

Upgrading firmware/bios/boot on Areca ARC-1210
I posted this same question on freebsd-scsi a few days ago but got no response there so I thought I try here. I want to update the firmware, bios, and boot code in my areca ARC-1210 raid controller and am a bit hesitant to do it for lack of any experience updating this card. I want to use the areca-cli program to do this and I see that the areca-cli looks like it supports updating the firmware (via the "sys updatefw" command), but I don't know if I can use this to update the bios and boot code as well or not. Can someone help me out on this? Also, is it ok to do this update while the system is up and using the card? I think this is the case (I suspect that the update doesn't really take effect till reboot), but was hoping someone with experience could comment. I also read somewhere on the Areca web site that you should update all three parts (firmware/bios/boot) prior to rebooting as otherwise the card may fail to operate due to mis-match of the code. Thanks, Bob -- Bob Willcox If you try to please everybody, nobody will like it.

For things that I need to do on a repeated basis where most of the variables are consistent, or for automation tasks I always use Perl. - tr, sed, awk etc. are part of the FreeBSD base system, while perl is not. This is another reason. I do have a couple of machines that do not have Perl installed on them, so when I need to do a quick change to multiple entries in a file, I'm quite used to using sed/awk. It had just been a while since I've used it to make more than one change per entry (well, since my tcpdump file example). Oliver posted yesterday three examples using sed, awk and tr. The one that I will stick with and will not have any difficulty remembering was this one: # tr '.\t' '_@' | sed 's/@.*/@example.com/' I am the most familiar with that one as I use sed on almost an every day basis. I appreciate all of the feedback. There have been some excellent methods that have been very wide ranging.

You will still have to forward the X11 authentication to the client machine with xauth(1) or xhost(1), I think. Using xhost(1) is much easier, but it's insecure.

I guess -X achieves a particular goal, that is being able to login to a remote box, run X11 apps and make them use your local X11 display. Everything else is beyond its scope... You can however use your favorite NAT to translate requests for, let's say: 192.168.0.1:6000 to 127.0.0.1:6000 and have the 127.0.0.1 bound socket exposed to the network...

Unfortunately fsck isn't able to cope with any arbitrary level of damage. If certain kinds of unexpected problems occur, it throws in the towel. In theory it might be possible to deal with your particular problem, but nobody has implemented it in fsck yet. Someone with intimate knowledge of UFS2 might be able to help you, possibly using fsdb(8), but this requires direct access to the file system image and is beyond what can be done through a mailing list. Usually such services cost money. (The price to pay for not having backups.) You might also have success using one of the various recovery or forensic toolkits out there, e.g. sleuthkit (it's in ports). > > PS: Better make good backups next time. > > More precise: Better make _at least any_ backups. :-) More than > 5 years without any (!) problem with FreeBSD and now this stupid > problem... :-( Well, there's nothing an OS can do against hardware failure (such as a crash because of power loss). Such failures can cause arbitrary damage to mass storage, especially if the power failure happens in the middle of writing a track, and especially when using "consumer grade" disks. Disks are cheap these days. Cheaper than your valuable data. So, a simple way to make backups is to buy an external disk (USB2, Firewire/IEEE1394, eSATA, or even a hot-swappable PATA drive tray), sync your system to it once per week, and store it in a safe place. If you're paranoid, then use two such disks alternating, so you have one good (safe, i.e. disconnected) copy at every point in time. If you're even more paranoid, store multiple backup disks in different places (e.g. one at home at one at your office, or at a friend's place, or even in a safe deposit box at your bank company), so you still have a good backup if your house burns down or an alien space ship crashes on it.

I think your attempts show very well why Steve wanted to avoid perl. :-) But seriously, a few other reasons might include: - tr, sed, awk etc. are part of the FreeBSD base system, while perl is not. - The perl command you wrote above is pretty much a sed command anyway (except you incorrectly used non-portable regular expression syntax). Why use perl to execute a sed command? - It is generally advisable to use the smallest, most light-weight tool that gets thew job done. In this case that's clearly not perl: Size of sed: 27 KB. Size of perl + libperl: 1126 KB Thats more than 40 times bigger. Of course, YMMV. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
