Lingering dhclient issue
by Alfred von Campe 23 Jun '11

23 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

In CentOS 4.1/2, what package contains this library: libstdc++-libc6.2-2.so.3? I installed a couple of the compat- packages, but this library is still missing.

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

Gnumeric
by centos＠911networks.com 31 Mar '08

31 Mar '08

Hi, I am trying to install Gnumeric in CentOS 4 and I can't. It complains about quite a few dependencies failing. It suggested installing some postgresql librairies, openldap librairies... I did that, now I still get: dependencies failed: libmdb/libmdbsq/libsqlite/libxbase/libtds. Is there a yum repository that has them or a yum repository for gnumeric? I have tried Dag, he does not, he has libgda, but that has other requirements... -- Thanks

[Semi-OT] Advice on large webmail setup
by Neil Thompson 03 Jan '08

03 Jan '08

Hi all, As the resident Linux guru, I've just been tasked with costing a webmail setup for about 600 000 users. They each have 10MiB (small, I know) mailboxes. The current setup has about 40 million web page accesses per month. Has anyone here any experience with this kind of thing? If so, any pointers as to software and hardware used, and any other advice would be appreciated. TIA -- Cheers! (Relax...have a homebrew) Neil THEOREM: VI is perfect. PROOF: VI in roman numerals is 6. The natural numbers < 6 which divide 6 are 1, 2, and 3. 1+2+3 = 6. So 6 is a perfect number. Therefore, VI is perfect. QED -- Arthur Tateishi

by Sharon Kimble 23 Nov '07

Congratulations to all the CentOS folding@home team members for breaking through the 200 world ranking barrier. Its taken a bit of time but we've all helped to do it. Our next target is obviously to achieve 150th in the world ranking. But, to help achieve that we're going to need more members and more machines. So, if you think it sounds interesting and you want to learn more, then please have a look at http://www.sharons.org.uk/cf.html or ask in #centos-social on irc, or in the usual mailing list. Theres always someone on hand to advise or to point you in the direction of someone who could possibly help. Thanks everybody, and full steam ahead to the next target! :) Sharon. -- 14:20:05 up 9 days, 21:44, 2 users, load average: 2.89, 1.72, 1.62 A taste of linux http://www.sharons.org.uk/taste/index.html efever http://www.efever.blogspot.com/ Centos 4.4, KDE 3.5.4-6.0, OpenOffice 2.0.3 Registered Linux user 334501 Get my public GnuPG key from http://keyserver.veridis.com:11371/export?id=6499064243027013735

CentOS4 and older megaraid
by Craig White 01 Sep '07

01 Sep '07

Release notes say no support for the RAID card in a box I just picked up...is there no hope for this box running 2.6 kernel? http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/release- notes/as-x86/ The kernel shipped with Red Hat Enterprise Linux 4 includes the new megaraid_mbox driver from LSI Logic, which replaces the megaraid driver. The megaraid_mbox driver has an improved design, is compatible with the 2.6 kernel, and includes support for the latest hardware. However, megaraid_mbox does not support some of the older hardware that was supported by the megaraid driver. Adapters with the following PCI vendor ID and device ID pairs are not supported by the megaraid_mbox driver: vendor, device 0x101E, 0x9010 0x101E, 0x9060 0x8086, 0x1960 <--- my card ---< The lspci -n command can be used to display the IDs for adapters installed in a particular machine. Products with these IDs are known by (but not limited to) the following model names: * Dell PERC (dual-channel fast/wide SCSI) RAID controller * Dell PERC2/SC (single-channel Ultra SCSI) RAID controller * Dell PERC2/DC (dual-channel Ultra SCSI) RAID controller * Dell CERC (four-channel ATA/100) RAID controller * MegaRAID 428 * MegaRAID 466 * MegaRAID Express 500 * HP NetRAID 3Si and 1M Both Dell and LSI Logic have indicated that they no longer support these models in the 2.6 kernel. As a result, these adapters are not supported in Red Hat Enterprise Linux 4. Craig
