SELinux and Perl script using sendmail
by Miark 10 Dec '07

10 Dec '07

I have a webpage feedback form that uses a Perl script to send e-mails with "| /usr/sbin/sendmail -t". It works just fine, but SELinux is complaining about it: SELinux is preventing /usr/sbin/postdrop (postfix_postdrop_t) "getattr" to pipe:[41117] (httpd_t) I'm a SELinux newb so I don't know what (if anything) to do about it. Suggestions? Miark

keeping a mirror of the updates repo
by Kai Schaetzl 10 Dec '07

10 Dec '07

I have a local mirror of CentOS5 base and updates. Now with 5 having become 5.1 and in case I just want to keep on updating (at the moment) is it enough that I update the mirror of updates or do I also need an update of the base repo?

5.1 Upgrade Not Working?
by Scott Moseman 10 Dec '07

10 Dec '07

So both "yum upgrade" and "yum update" now are complete and there's no new packages. However, when I attempt to check my version, I'm still showing 5. # cat /etc/redhat-release CentOS release 5 (Final) I remember seeing 5.1 repositories being access for the upgrades. Is it possible my system did not upgrade? # uname -r 2.6.18-53.1.4.el5.centos.plus Thanks, Scott

How prevent loading of audio driver at boot?
by Steve Snyder 10 Dec '07

10 Dec '07

CentOS v5.1 insists on loading about a dozen audio-related drivers at boot time. Since this is a server machine, it will never run applications that require sound output. I tried setting "alias snd_cs46xx off" in modprobe.conf. Yet the system still loads that driver and the many, many other audio drivers that go with it. How can I disable the loading of audio drivers at boot time? Thanks.

Re: [CentOS] remote ssh to machine how display firefox
by Brent L. Bates 10 Dec '07

10 Dec '07

I've looked over the man page for `ssh' and `ssh_config' on several systems and I think people have it backwards. The pages I read indicate that `-X' is more secure than `-Y'. Under the `-X' part on several systems I have access to says: "For this reason, X11 forwarding is subjected to X11 SECURITY extension restrictions by default." The `-Y' says: "Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls." I would think being subjected to security controls would be more secure than not being subjected to them. -- Brent L. Bates (UNIX Sys. Admin.)

centos 5.1 kernel crash on 2.6.23.9
by Jerry Geis 10 Dec '07

10 Dec '07

Hi all - looks like I have a kernel dieing on me. This is an AMD 6400+ with 4 GIG ram. I am using ext3 and software raid on 500G drives. (2) of them. I have an external 1T usb disk connected for backup. This is running 2.6.23.9 as I wanted to use kvm-amd. It has died on me twice. Funny thing is it happens when I am NOT using the machine. Any thoughts?

Trouble getting all my com-ports (ttyS*)
by Christopher Thorjussen 10 Dec '07

10 Dec '07

I just installed CentOS 5.1 on a Dell Vostro 200 (Intel G33) which has a Sunix PCI-Express (x1) 8-port RS-232 card installed. For me it looks like only 4 ports are recognized, but I'm not sure if it's even working with those 4. >From 'dmesg' I see this: ...

Re: [CentOS] SOLVED - Can't build CentOS 5.1 kernel from source
by MHR 10 Dec '07

10 Dec '07

Problem solved (thanks to Jim and some careful thinking): I was building the 2.6.18-53.el5.src.rpm kernel (the stock RHEL release source) instead of the 2.6.18-53.1.4.el5.src.rpm (the CentOS update source). For the record, the problem was that the RHEL stock kernel source needs the rhel and olpc sections in the spec file that the CentOS kernel does not (if that makes no sense to you, read the wiki). Regards. mhr

using vnc server and login kills X login
by Jerry Geis 10 Dec '07

10 Dec '07

I changed my X driver from nvidia to xv. Now when I vncviewer into my machine it KILLS my current logged in user. When I try to login it accepts my login looks like its going to do it then kills my X windows screen. When I reconnect I'm back at a login again. This is for my account user geis. If I login as root it all works fine. I was told to change from nvidia to nv as some other interaction was killing my machine with the nvidia drivers. Under the old nvidia driver I did not have an issue. Any ideas? Jerry
