I just build a new server and once I was able to log on, I did a yum -y update The download (~100Mb) and updates all completed. It is now in the cleanup and hung on 56/77 it has been on that entry for a couple hours. How do I recover from this? close terminal window, open new and then: yum clean ??? Should I reboot prior to the clean?

Is tun module is disable in Centos4.0 the kernel version is 2.6.9-34.0.1.EL ? How do I enable the tun interface in Centos4.0 means kernel compiling or there is anyother kernelmodule for tun? Thanks & Regards Ankush Grover

Corrupt file systems
by Russell Butturini 27 Jul '06

27 Jul '06

Hello all: My company builds Linux based web content filters using CentOS 4.3 as the base. We always apply updates to the new machines from the default repositories before deployment. Recently, the last two CentOS machines we built on Dell Dimension 1100s have failed, and the root file system seem to be getting corrupted. An e2fsck tries to recover the journal, but never repairs the machine enough to completely boot up. This only seems to be happening on the Dimension 1100s, as we have several other machines built with the same kernel version and software running on it that have not failed. The machines are Celeron-Ds, 2.4-2.8 Ghz, with either 256 or 512 MB of RAM and IDE hard disks. Does anyone know of any issues which could be causing this? Any fixes?

Centos 4.3/ 64-bit: Java/ Tomcat Optimization
by Karl R. Balsmeier 27 Jul '06

27 Jul '06

Hi, I have been steadily migrating machines, about 50-70 of them to Centos 4.3, mostly using Opteron Dual Core/ Tyan boxes of Supermicro origin. They perform apache, mysql, tomcat and qmail work, depending where they exist The main reason from the programmer side (i'm a sysadmin/ engineer) is the larger "heap size" to satisfy some of the needs. Since Java/Tomcat applications can also be I/O intensive, i'm looking at things from the systems side to improve on, kernel settings, filesystem choice, RAID configuration, etc. Is there anyone out there in the Centos 4.3 community that's looking at similar optimation interests, and if so, what have you found thus far? Mostly i'm curious about stability, features, bugs and other aspects native to Centos 64-bit/4.3 and running Tomcat/ Java on it. Right now we are at Java 1.4, but will likely make the jump to 1.5 within the next 180 days. So far the developers are happy with the first box I made for them, but I did not customize the kernel, or make any in-depth adjustments, just handed them a larger heap size and they seemed quite happy with that in itself. Clustering, keeping alot of single machines separate, getting one large machine with alot of mem/cpu/i/o capacity, these are all being examined. Just curious what you think, or if you know of any great resources on the subject. I'm in a similar boat wih regard to Mysql, but that's another story, and I have alot of actual research on that to share. -karlski

What I've done is to switch VCs into one of the text based terms while the formatting is going on. Once it finishes, the install goes just like normal. I'm using an AMD Opteron, and that almost always hangs during formatting... I use the normal linux kernel, so not sure if the 586 option would apply to my situation. HTH Mark

RE: [CentOS] OT: remote power cycling

If you need to also provide power protection, many UPS units also provide the ability to cycle one or more of the power outlets. We use both Tripplite and APC products with the network interface card (Web/SNMP). For out-of-band management, it seems likely that you could do something with the serial port and a modem but I haven't personally implemented that strategy. Regards, paul Paul M.

Hi, I have a cronjob that executes a script that has some echo statements in it and the commands in it also generate output (it copies files, reloads services, etc...). Recently, cron stopped sending its output by e-mail. I restarted cron, without success. Any ideas where I shoud start to debug this? Regards, Ugo
