It would be better if it was on it's own. Phil.

how to properly change the timezone
by Nataraj 08 Jul '10

08 Jul '10

Hi, I have a Centos 5.5 server with no GUI installed. I have several times changed the timezone by copying the correct file to /etc/localtime, however something keeps changing it back. I'm not sure if this is a yum update or what. Without installing the graphical tools, how can I update the timezone in such a way that the /etc/localtime file won't keep getting clobbered. Thank You, Nataraj

How current are packages?
by Matthew Valentino 08 Jul '10

08 Jul '10

I'm relatively new to CentOS. I ordered a VPS and requested CentOS 5.5. As I was installing packages, I noticed that some of the versions are pretty old - for example, Postfix is v 2.3 in the repo (and, according to Postfix's website - no longer mainted). Is this a security risk as the current version is 2.7.1? Building and compiling Postfix from source seems to cause additional problems with yum, so I'm not sure what to do other than perhaps switch to something like Fedora. Perhaps there's a third-party repo with updated packages that I haven't found? Thanks, Matt

xulrunner-devel dependencies
by Bowie Bailey 07 Jul '10

07 Jul '10

What's the deal with all of the new dependencies for xulrunner-devel in the last update? I'm updating my servers and the update for xulrunner-devel is forcing me to install 43 new packages! Is this a packaging problem, or are all of those packages really needed? For the moment, I've been removing xulrunner-devel from my machines to avoid the problem. I figure since it is a development package, I can always reinstall it later if I need it. Bowie

ntp server
by Jerry Geis 07 Jul '10

07 Jul '10

I have a need to run a centos server CUT-off from any connected network. So the NTP server that is running on this very small network cannot connect to any other site to do what NTP does. however, I have devices on this small network that I wish to use the centos server as the time source and run ntpd. However - it seems like ntpd server does not like to run this way. There is a LONG delay before it finally says OK - no one to talk to so I'll just give the time anyway. Then things start working. Is there some method to SKIP this long delay??? It seems like its 15 or 20 minutes. I need to bypass that delay or tell ntpd "I dont care about others time" just provide the time you have. Thanks, Jerry

security compliance vs. old software versions
by Les Mikesell 07 Jul '10

07 Jul '10

What's the correct response to a security scan that points out that apache versions below 2.2.14 have multiple known vulnerabilities? Is there an official document about what known vulnerabilities have been fixed in the RHEL/CentOS updates or do you have to wade through the changelog to try to find each thing? -- Les Mikesell lesmikesell(a)gmail.com

KVM virtual guest can not use serial port
by Doug Coats 07 Jul '10

07 Jul '10

I hope this is not to far off topic. I have a Windows 2003 guest on a CentOS 5.5 KVM host. I need to use the serial port on the win2003 guest for the application it is serving. I have no idea what needs to be done but it looks like the linux host is trying to use the serial port as the priamary console but I don't really understand what that is or where it is configured. What I need is for the host to ignore any traffice over the serial port and to pass it to the guest. On the host, ls -l /dev | grep ttyS, returns: crw-rw---- 1 root uucp 4, 64 Jul 6 10:17 ttyS0 crw-rw---- 1 root uucp 4, 65 Jul 6 10:17 ttyS1 crw-rw---- 1 root uucp 4, 66 Jul 6 10:17 ttyS2 crw-rw---- 1 root uucp 4, 67 Jul 6 10:17 ttyS3 It only has 1 serial port so I don't know why ttyS1-S3 are listed. On the guest it says that Com1 is configured and working properly. On the Virtual Machine Hardware tab of the guest it lists a Serial 0. Details: Serial Device (Priamary Console) Device Type: pty Target Port: 0 Source Path: /dev/pts/2 Any help would be greatly appreaciated. Thanks!!!
