nscd segfaulting on centos 4.5
by jlee 10 Oct '07

10 Oct '07

Does anyone know if there is a fix for nscd segfaulting after a short period of time. Googling for it came up with one result that suggested deleting the files in /var/db/nscd , but that didn't help. Another result was about run away processes which is not the problem I'm having. They are x86_64 boxes. output from /var/log/messages Oct 9 12:56:38 lyra kernel: nscd[11660]: segfault at 0000002b401fee8b rip 000000552aab7966 rsp 00000000408029e0 error 4 Oct 9 13:16:38 lyra kernel: nscd[12540]: segfault at 0000002b401fee8b rip 000000552aab7966 rsp 00000000408029e0 error 4 output from dmesg nscd[12540]: segfault at 0000002b401fee8b rip 000000552aab7966 rsp 00000000408029e0 error 4 nscd[13640]: segfault at 0000002b401fee8b rip 000000552aab7946 rsp 0000000040a039e0 error 4 output from uname 2.6.9-55.0.9.ELsmp #1 SMP Thu Sep 27 18:28:00 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

CD emulation (a la daemontools)
by Chris Mauritz 10 Oct '07

10 Oct '07

I was wondering if anyone was aware of a method for mounting virtual CD devices with CD image files. I keep images (.CUE/.BIN pairs) of my CD collection on a NAS appliance tucked away in my closet. I'd like to write a script to mount each one, create ID tags, rip the tracks, then move along to the next one. I figure with a quad core opteron, it should be able to crank through them in a few days (it's a few thousand CD's worth of images). Anyone done this before with their trusty CentOS box? I'd be using CentOS 5. Best,

Re: [CentOS] PCI-X SATA RAID Controllers
by Steve Bluck 10 Oct '07

10 Oct '07

Thanks for the replies (and thanks Matt, PCI-e is indeed what I meant -brain freeze moment), I realise "linux dd" works -and is in fact how I've installed CentOS 5, but unfortunately I require a card (PCI even!) that will not require driver updates every kernel update and support a minimum of 6 ports in RAID 1. Being a noob at Linux I'm having trouble sourcing a card that is supported in the 2.6.18 kernel without the need to install drivers, and replies from manufacturers either evade the question or require a Masters degree in Linux, so I thought I'd tap into the combined knowledge of everyone here! So I'm still open to suggestions! Cheers Steve > I would recommend PCI-E if you want the fastest card available, and > using the 'linux dd' option before you install CentOS 5 allows you to > load the 3ware kernel module prior to installation which is what I > did to get my 9650SE-16 working. ;-)

ssh X11 forwarding not working
by James A. Peltier 10 Oct '07

10 Oct '07

I'm having problems with ssh.com and X11 forwarding ssh: SSH Secure Shell 3.2.0 (non-commercial version) on i686-pc-linux-gnu I am in the process of testing some of my machines with CentOS 5 x86/x86_64 and have run into a bit of a snag. X11 Forwarding is not working. I've tried all combinations of (+/-)[Xx] and it doesn't work, seemingly it doesn't want to set the environment variable properly and therefore doesn't know where to send the X requests. Any hints? I've checked the ssh config files and they seem to be identical to the config files on our existing SuSE 10.0 machines which are working. This is troubling indeed. -- James A.

NFS and Firewall
by Timothy Kesten 10 Oct '07

10 Oct '07

Hi Folks, I'm using VMWare on a Linux Host (CentOS) with a Linux-Guest Sidux). And I'd like to use NFS. Furthermore I'd like to use the Firewall in CentOS with this little GUI. If I activate this firewall then my Guest says "no route to host" on mounting nfs. Firewall disabled -> no problem occurs. Is there a solution to use firewall _and_ nfs ? Please, no iptables scripts. I'd like to use this small GUI for the firewall. Thx Timothy

two internet connections questions
by Jerry Geis 10 Oct '07

10 Oct '07

I have two internet connections. One is a partial T1 of data (and rest voice) the other is business cable. Both connections come into my office into (2) centos 5 boxs with 2 ethernet cards in each box. The second ethernet card is 192.168.1.59 and 192.168.1.1 respectively. I have all my DHCP settings setup for a gateway of 192.168.1.1 In the event that the internet connection is DOWN (box is fine just the cable modem is down) how do I set things up so I can take advantage of the second internet connection? Thanks for any tips. Jerry

Look for users in both LDAP and /etc/passwd
by Tronn Wærdahl 10 Oct '07

10 Oct '07

Im running CentOS 5 with samba configured as PDC, with samba 3.0.24 and openldap-servers-2.3.30-2. My /etc/nsswitch.conf is like this: passwd: files ldap shadow: files ldap group: files ldap The problem is when I try to restart LDAP (/etc/init.d/ldap restart) then the init script just hangs. I suppose it will try to run slapd as the ldap user The ldap user is not in LDAP only in /etc/passwd, how can i configure my system to look for users first in LDAP and then in /etc/passwd When I remove LDAP from my /etc/nsswitch.conf, so it looks like below passwd: files shadow: files group: files then ldap start up nicely, but then my LDAP users can't sign in I tried to do different changes in pam, but without any progress Please advice

yum $releasever thinks it's 1 instead of 3
by Steve Campbell 10 Oct '07

10 Oct '07

I just upgraded one of my Tao boxes to Centos 3. The usual procedure is to do a yum update twice, and all is fine. This time, I had to rebuilddb before I could run the second yum update, and once I started this, yum fails. It says that $releasever is "1.0". Now I realize I could manually edit my yum.conf and make it go to 3, but this may not fix the problem down the road. Can someone tell me where this variable is defined, and any suggestions on how to fix this problem, please? Might a reinstall of yum packages fix this, as a last resort? Thanks very much.

yum $releasever thinks it's 1 instead of 3 - Nevermind
by Steve Campbell 10 Oct '07

Never mind. I updated with the centos-release rpm and that seemed to fix it. Thanks for any who may have offered already. Original below: I just upgraded one of my Tao boxes to Centos 3.
