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

Reformatting a USB drive
by Todd Cary 29 Sep '08

29 Sep '08

I have a USB drive that has been formatted as NTFS. Can I reformat it? I have identified these properties about it /dev/sda1 /media/Extrnl_Bkup Not sure what to do next since the GUI will not mount a NTFS disk (expected). Todd -- Ariste Software 2200 D Street Ext Petaluma, CA 94952 (707) 773-4523

Reg. VNC server and Windows and Centos interworking
by Padmaja 13 Jul '08

13 Jul '08

Hi all, I have a Windows XP PC and a Centos PC (Centos 4.3 release, kernel- 2.6.9-34.EL) which are in the same LAN. Currently, I am able to use VNC server on the centos to view the Windows PC, but not able to view the Centos PC from the Windows PC. This applies for even file sharing also. The samba server is running and I can view the windows network from Centos PC but in the Windows network, not able to view the Centos PC. Also not able to print from Centos to the LAN printer. Any help is greatly appreciated. Thank You, Padmaja

NFS options on kernel parameters
by vincenzo romero 13 Jul '08

13 Jul '08

Hello, I am running an NFS server/PXE on a Cent OS 5.1 server. I have defined an NFS export with "no_root_squash" option in my /etc/exports file: # # NFS Export Files # /export/images *(rw,sync,no_root_squash) ... A client PXE boots as a diskless station to the above server into a root-NFS directory underneath the above /export/images export. When the client boots; the NFS export is NOT root-Squashing - whenever I touch a file, it is created as user nobody and NOT root. I would like to NFS root-squash the root directory. I believe that I am missing to pass a parameter in my kernel - (defined in .. /pxelinux.cfg/default) .. currently my kernel parameters are: APPEND root=/dev/nfs rw nfsroot=192.1.2.5:/export/images/root-fs ip=dhcp ... would anyone be kind to provide advise on how I can mount my client so that I am ensure that the "no_root_squash" setting is enabled? thanks in advace. -- best, Vince

Setting up a chroot
by MHR 10 Jun '08

10 Jun '08

I'm trying to build GNOME (to run a more recent version than 2.16.* on CentOS 5.1) and I keep running into a lot of rather strange problems. I'm wondering if this might have something to do with my hybrid 64 and 32 bit general environment, so I want to try a pure 64-bit chroot. I've never done this before, and I'm not entirely sure how to, and I didn't see anything particularly on point, either at centos.org or google. If I missed it, just say where and that should be enough. Guidelines? Suggestions (other than "go away" or other physically difficult crudities :-)? Thanks. mhr

Frequent Gnome Terminal crashes in CentOS 5.1
by Alfred von Campe 06 Jun '08

06 Jun '08

Ever since I upgraded all my systems to CentOS 5.1 I have been getting reports from users about "all their windows disappearing". A little digging revealed that they meant all gnome-terminal windows. Since there is only one gnome-terminal process by default for all your open terminal windows and tabs, a crash of that process means losing all your terminal windows. These crashes often (but not always) occur over night when the system is otherwise idle. A quick Google search found a problem on Ubuntu related to VTE (the terminal emulator widget used by gnome-terminal) but not much else of interest. Has anyone on this list experienced this? I find it hard to believe I'm the only one. I never saw this issue while running CentOS 4.X on these systems... Alfred
