Lingering dhclient issue
by Alfred von Campe 22 Jun '11

22 Jun '11

I recently reconfigured some CentOS 4.3 systems that were using DHCP to use static IP addresses. At the same time, the systems were moved to a new VLAN. Here is the approximate sequence of events that took place: 1. ifdown eth0 2. edit /etc/sysconfig/network-scripts/ifcfg-eth0 with static IP address 3. wait for network folks to reconfigure switch 4. ifup eth0 I may have reversed steps 1 and 2 on some of the systems. The problem was that the dhclient process didn't go away, and kept renewing the old lease. Our DHCP server is configured to contact the DNS server and update the entry for each host it serves. So the DNS entries for these systems were pointing to the old address in the old VLAN. The eth0 interface itself just kept the static IP address for which it was configured. It took me a while to figure out what was going on. My question is, what could I have done to avoid this (other than killing the dhclient process)? Is there a better way to reconfigure an interface to use a static address? I am not interested in solutions that involve using a GUI (i.e., only command line solutions). Thanks, Alfred

Dell Poweredge R300
by Nicholas 07 Jun '09

Hi all, Just found out that the Poweredge R300 cant even load the CentOS 5.2 64bit installer. Had to revert to Ubuntu. Seems its a driver problem. Pity, but does this kind of case apply to many other servers? --- OSCC MAMPU MyMeeting Version 2.0 Release http://knowledge.oscc.org.my/solution-areas/application/mymeeting

I have an old RHEL3 box that I am upgrading to CentOS5. I picked up a new Dell Poweredge R200 to use for that. Is there an easy way to copy all the user accounts and existing mail from the old server to the new one? Thanks. -- -=/>Thom

Antivirus for CentOS? (yuck!)
by Amos Shapira 25 Apr '09

25 Apr '09

Hi All, Yes, I know, it's really really embarrassing to have to ask but I'm being pushed to the wall with PCI DSS Compliance procedure (http://en.wikipedia.org/wiki/PCI_DSS) and have to either justify why we don't need to install an anti-virus or find an anti-virus to run on our CentOS 5 servers. Whatever I do - it needs to be convincing enough to make the PCI compliance guy tick the box. So: 1. Has anyone here gone though such a procedure and got good arguments against the need for anti-virus? 2. Alternatively - what linux anti-virus (oh, the shame of typing this word combination :() do you use which doesn't affect our systems performance too much. The reviewed servers run both Internet-facing web applications and internal systems, mostly using proprietary protocol for internal communications. They are being administrated remotely via IPSec VPN (and possibly in the future also OpenVPN). Thanks, --Amos

ext4 in 5.3
by Jerry Geis 12 Feb '09

12 Feb '09

Hi guys - I'm really looking forward to 5.3 for the potential of ext4. I am moving/copying image files lately 8G file and it is slow. I am hoping that ext4 really speeds that up. My question is: will we be able to boot ext4 file systems? Will the boot partition still be ext3 and then have to mount the ext4 filesystem? I did not see mention of it in the release notes. Thanks, Jerry
