Where to look or command
by Sam Drinkard 25 Nov '05

25 Nov '05

List, I've got a process(s) that have been exiting on a signal 11, but not all the time. I suspect it's memory related, and I was wondering, is there any way to tell exactly how much memory a particular process has in use at the point it sigsev's ? I can't sit here and watch top or the system monitor, but thought maybe something might be saved somewhere after the fact. The processes are using at the moment, 1.4gb of memory and no swap. I've not seen swap go active during any of this process run, and the machine has 2 GB memory installed. Rather hard to trace down the exact activity when it happens. Thanks.. -- Snowman

B.T.D.T! catch the signal in a handler of your own, do analysis as needed, then clean up and exit (saving a core file if you need one). AIUI, the signal handler runs in the space of the process/thread that hit the trap.

boot with more scsi card
by Farkas Levente 25 Nov '05

25 Nov '05

hi, we've got a server with a 8 port 3ware card and 2 ide system disks. now we'd like to replace the ide disks with scsi disks or sata disks (these also recognized as scsi in the kernel). but we can't boot from it. the problem are twofold. first in the normal case the first scsi host scsi0 id the 3ware card, but grub only see the first 8 disk so if the system disk are sdi and sdj the one can't boot from it. on the other hand if one disk is removed from the 3ware card or the kernel reorder the scsi disk and sdi become sdh which is also a problem both for the bios and for the kernel. if i change the order in bios, the kernel still use as 3ware scsi0. if i use scsihosts kernel param or load the scsi driver (through modprobe.conf) in a reverse order then the kernel hang forever during the initialization of the 3ware driver. any tip? thanks in advance. yours. centos 4.2 kernel-2.6.9-22.0.1.EL 3w_xxxx 1.26.00.039 -- Levente "Si vis pacem para bellum!"

which script will run before and after network started
by Robin Mordasiewicz 25 Nov '05

25 Nov '05

Is there a script which I can customize which will run before doing service network stop and a script which I can run after doing service network start I see that /sbin/ifup-local runs after each interface is brought up, but I cannot figure out which scripts will run after all the interfaces are brought up.

Request rewriting - regular expressions
by Tom Brown 24 Nov '05

24 Nov '05

OK not directly CentOS this one but.... I'm trying to write a rewrite rule that uses the same(tm) syntax as apache mod_rewrite (or at least it understands it) The following works by catching ANY url comfigured in the web server and rewriting it with the correct http status code. The issue is that i need to redirest URL1 to 1st location and URL2 to second location and i'm trying to get my match syntax correct. Can anyone advise on the reg expression that would distinguish betweek URL1 and URL2 thanks! match URL into $ with ^/$ if matched then set SCRATCH:LOC = http://www.example.com/en/homepage.html set Response = 302 set OUT:Location = %{SCRATCH:LOC} set OUT:Content-Type = text/html set Body = set Body = This page has moved, please visit <ahref="http://www.example.com">here</a> instead. endif

samba windows 2000 and windows 2003
by Peter Farrow 24 Nov '05

24 Nov '05

Dear All, I have two AD domains, one running on Windows 2000 and one running on Windows 2003. Each with XP clients, and no trust. Ihave a linux file server running samba 3 on Centos 4.2, the smb.conf file specifies that security=server, and points the password server to the operations master on the Windows 2000 domain. All clients and 2000 servers on the Windows 2000 domain, (xp or otherwise) can access the smb shares on the linux box no problem. The windows 2003 server and XP clients on that domain cannot, first time round they receive the error "The request is not supported", after adding this: client signing = auto to my smb.conf file I get the error "the filename, directory name or volume label syntax is incorrect." I tried disabling packet signing on the win2k3 box group policy - it made no difference. I disconnect the linux server from using the windows 2000 server as a password server and setup up separate smb accounts and it works fine from the win2k3 box. I believe this is something to do with packet signing but just cant seem to find out the problem. I fixed this on a previous linux server the other way round (mounting 2k3 on Linux, but can't remember how I did it), I note that that server has a /proc/fs/cifs directory where I can kill packet signing, but the new server with the current problem does not. However I don't recall installing cifs nor does it seem to be on the older server. Any ideas? Pete

trimming CentOS - flash disk
by mbneto 24 Nov '05

24 Nov '05

Hi, I am switching a few specific servers with CentOS 4.2 and I'd like to use in some a flash disk (CF card). Unfortunately the minimum size of a centos install seems to be around 600 Mb (at least that's what I got) and 1 Gb card are still expensive and, IMHO too big if all you want is a gateway/iptables machine or a NFS server. There are other OSes and even distros that have a smaller footprint (way down to 60 Mb), and I am not talking about those 'embedded' distros like monowall, openwrt etc. I was wondering if there is a quick way to reduce the size and if there is a "slim process" in the works to do that.

RE: [CentOS] Frontpage Extensions
by Bob Pierce 24 Nov '05

24 Nov '05

William, The package from nuonce.net sounds interesting. But if that doesn't work for you, the extensions from Ready To Run do work on Centos4.2. We just finished putting together a hosting server with FP extensions on Centos4.2. Although there are a few initial headaches with configuring everything properly most of the tips we needed came from the ready2run site. If you run into specific problems feel free to ask. Our server's been working good for a few months now. We just have to be careful about the permissions on /var/log/httpd/fpcgisock after yum updates.

Where is the proper place to set the group ownership of devices under /dev/ in Centos3.
by Alexander Georgiev 24 Nov '05

24 Nov '05

Dear list members, I have a DVD writer /dev/scd0 which after reboot has the following ACL: brw-rw---- 1 root disk 11, 0 Sep 9 2004 /dev/scd0 However I want to set this device group to "Domain Users" in order to enable its members to burn DVDs. If i invoke: #chgroup "Domain Users" /dev/scd0 the next reboot will override the group back to "disk". Is there a standard/reglamented way to set the group ownership of a device file. Best regards! ageorgiev
