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.

Don't forget to use torrents for your downloads!
by William L. Maltby 23 Feb '10

23 Feb '10

For those who may forget, usin torrents to download and share the new images will get you faster downloads (if enough folks participate) if you have a "fat" pipe and alleviate the load on the CentOS servers. I have a "chubby" pipe (~ 1.2MB/sec) and got the stuff really quickly earlier today. If your torrent has distributed hash table capability, I suggest that you also use that feature. Happy sharing! -- Bill

Certificate system
by J.Witvliet＠MINDEF.NL 07 Aug '09

07 Aug '09

Hi all, Can anybody inform me wether the "RedHat Certificate System" or actually a CentOS equivalent is available for CentOS. Just skimmed on a download site through the RPM's for 5.3 and I couldn't find it. According to their pressrelease, it the code should be gpl, allthough I can't find any rpm for RH, FC or Centos. It seems that this is one of the few CA-packages for large scale deployment of certificates. Only alternative AFAIK is OpenCA, which seems to be hardly maintained... ( binaries on their site are old, and source code yields lots of errors during build..) Defensie/CDC/IVENT/Research en Innovation Centrum Ing J.

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

Weird performance problem
by Ugo Bellavance 24 May '09

24 May '09

Hi, I'm running a CentOS 4. server and I sometimes face a weird problem. It is a weird performance problem, and here is how I discovered it. This server runs OpenVZ virtual machines, and one of them is an asterisk server for my personal use. The first symptom of the problem is that the voice quality became flaky. So I logged on the server to see what could be eating cpu cycles, when I ran top, it took almost one minute before top actually showed. Another hint is that when I run dstat (a monitoring utility that is a mix of iostat and vmstat and other stats), I often get a "missed xx ticks", where xx is a number. Example (current) (sorry for the wrap): ----total-cpu-usage---- -dsk/total- -net/total- ---paging-- ---system-- usr sys idl wai hiq siq| read writ| recv send| in out | int csw 3 2 93 2 0 0| 106k 273k| 0 0 | 0.2 0.4 |1039 389 3 6 91 0 0 0| 0 6416k| 276k 275k| 0 0 |2160 6822 missed 55 ticks 4 10 84 2 0 0|1200k 1992k| 82k 93k| 0 0 |1188 6275 missed 29 ticks 1 0 99 0 0 0| 0 1312k| 65k 66k| 0 0 |1050 1114 missed 38 ticks 2 1 96 0 0 0| 0 1168k| 57k 59k| 0 0 | 491 877 missed 13 ticks 3 1 94 1 0 0| 0 6016k| 181k 176k| 0 0 |2169 5996 missed 50 ticks 4 2 91 1 0 0| 28k 8744k| 216k 214k| 0 0 |2159 5438 missed 37 ticks 1 1 98 0 0 0| 0 2632k| 93k 91k| 0 0 | 983 1381 missed 34 ticks 1 1 98 1 0 0| 0 5624k| 113k 110k| 0 0 |1569 2643 missed 52 ticks 1 1 98 1 0 0| 0 2432k| 29k 28k| 0 0 | 679 647 missed 12 ticks 0 0 100 0 0 0| 0 0 | 60B 374B| 0 0 | 13 15 2 3 94 0 0 0| 0 1872k| 209k 210k| 0 0 |1375 3590 missed 30 ticks The problem is currently occuring, but it doesn't seem to be affecting voice quality for now, so I have some time to try to find the cause. The only solution I've found up to now is to reboot... But hey, this isn't a Windows 98 machine :)! I tried restarting the VZ system, which restarts all the VMs, but it didn't solve the problem. I can't tell if the problem occurs on a stock centos kernel, because the server is running production (but non-critical) virtual machines, so it is always running the openVZ kernel. So here is what I've done for now: - Top shows a load of about 0.4 - vmstat 1 10 shows this: procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 592 191092 381720 537956 0 0 53 68 4 3 3 2 93 2 0 0 592 190720 381720 537956 0 0 0 0 32 60 1 1 98 0 0 0 592 191092 381720 537956 0 0 0 0 41 59 0 0 100 0 1 0 592 191092 381728 537948 0 0 0 2584 311 96 10 4 66 19 0 0 592 189968 381732 537944 0 0 0 2080 222 174 2 3 79 16 0 1 592 189968 381732 537944 0 0 0 3244 170 73 10 4 73 12 0 0 592 190216 381732 537944 0 0 0 136 76 113 1 2 93 4 0 0 592 189844 381732 537944 0 0 0 0 33 69 1 1 98 0 0 0 592 189844 381732 537944 0 0 0 0 24 32 0 0 100 0 0 0 592 190340 381732 537944 0 0 0 0 28 42 0 0 100 0 iostat -x 1 (excerpt) Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 171.00 0.00 124.00 0.00 2368.00 0.00 1184.00 19.10 0.14 1.13 0.02 0.20 sdb 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdc 0.00 171.00 0.00 124.00 0.00 2368.00 0.00 1184.00 19.10 0.17 1.35 0.02 0.30 sdd 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md1 0.00 0.00 0.00 294.00 0.00 2352.00 0.00 1176.00 8.00 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.00 294.00 0.00 2352.00 0.00 1176.00 8.00 0.30 1.01 0.02 0.50 dm-3 0.00 0.00 0.00 294.00 0.00 2352.00 0.00 1176.00 8.00 0.30 1.01 0.02 0.50 dm-4 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-5 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-6 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 Any insight would be greatly appreciated.
