Setting up a simple NAT on CentOS 3.5
by Robert Moskowitz 20 Dec '05

20 Dec '05

Well I think this system is back on 3.5. How do I tell? Have not used it in a while... I need a NAT for some quick testing and this box was available. Only a 6gb drive, so I can't install Astaro (which I have licenses for). So is there a simple way to turn on NATing? Should I upgrade to 4.2? This box is behind a firewall, so security risks are not the issue. This time.

Where is the kernel source code???
by lnthai2002＠aim.com 20 Dec '05

20 Dec '05

I have centOS 4 installed on my machine but some how it does not support my TV capture card (bt878) in the kernel, so i want to recompile the kernel to add support for my device. However, i cant find centOS 4 kernel source code. I have read some messages in the mailing list and someone said that i just need to yum install kernel-sourcecode to get the source code, i did it but i yum reported that there is no package matched.

Compaq V2000 laptop no USB recognized
by Jerry Geis 20 Dec '05

20 Dec '05

To continue here with problems on this compaq v2000 laptop, I put kernel source on a USB disk and plugged it into the v2000. NOTHING IS recognized. I tried to manually mount the disk and nothing either... I thought USB was well established.... I thought trying to recompile the kernel for realtek support might get my networking going... I am stuck??? Jerry

It's not supposed to start in runlevel 3. It's only supposed to run in levels 4 and 5. > The init process only runs K* under runlevel 4 (rc4.d) when exiting > runlevel 4, then runs all of the S* stuff under the new runlevel. > $0.02, no more, no less .... That's not what the rc script appears to be doing. It simply checks the current runlevel and then runs all the scripts in that directory (kill scripts first, and then start scripts). -- Bowie

Hlp with server load
by Chris Mason (Lists) 19 Dec '05

19 Dec '05

I have a system that is running into problems with high load, however, even when I shut down everything that could be loading the system, the load continues to rise. I can't see anything that is causing the load. Any ideas? 08:36:06 up 1 day, 10:57, 3 users, load average: 19.98, 19.30, 17.29 90 processes: 75 sleeping, 2 running, 13 zombie, 0 stopped CPU states: cpu user nice system irq softirq iowait idle total 0.1% 0.0% 0.0% 0.1% 0.0% 0.0% 99.6% Mem: 511916k av, 317756k used, 194160k free, 0k shrd, 35040k buff 208896k actv, 67280k in_d, 10488k in_c Swap: 2048276k av, 5872k used, 2042404k free 172064k cached -- Chris Mason

compaq v2000 laptop -- realtek RTL8100C?

The reason I ask is because while the RTL8100 is supposed to be MAC compatible with the RTL8139, I'm finding this is not the case. E.g., https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=175971 >/ Other distros (namely suse) said there was no problem with />/ this was detected and worked. />/ Mine does not work on either of the 2 V2000 laptops I have. />/ I tried manually loading the 8139cp module then restarting />/ the network and that did not do it. / Nope, the 8139cp didn't work at all. The 8139too driver loads, but doesn't communicate at all. ------------ Thanks Bryan, I also tried going out to the realtek.com.tw web site. They only have linux drivers showing for kernel 2.4.X Should I try that since my kernel is 2.6.X? Jerry

I found that by looking through the 'rc' script not long after I posted. I finally determined that the script was properly creating and deleting the lock file, it was just named wrong. The lock file must be named either 'subsys' or 'subsys.init'. This one was trying to use 'subsys-init'. Changed the dash to a period and the problem went away. Thanks for the help! -- Bowie

Hi, I have a compaq V2000 laptop. Specs for network say its a realtek 8139/8139C+ NIC. Other distros (namely suse) said there was no problem with this was detected and worked. Mine does not work on either of the 2 V2000 laptops I have. I tried manually loading the 8139cp module then restarting the network and that did not do it. Any ideas? Jerry

use chkconfig to change service startup order
by Erick Perez 19 Dec '05

19 Dec '05

Hi, I have my httpd process that starts in runlevel3 with the following info # chkconfig: - 85 15 # description: Apache is a World Wide Web server. It is used to serve \ # HTML files and CGI. # processname: httpd # pidfile: /var/run/httpd.pid # config: /etc/httpd/conf/httpd.conf the filename is /etc/rc.3.d/K15httpd However I installed an antivirus that uses a tomcat process that *must* be started prior to apache. the antivirus has the filename /etc/rc3.d/S99ISproxy How can I make the httpd start *after* the S99ISproxy process?

Setting up software IDE RAID
by Kai Schaetzl 19 Dec '05

19 Dec '05

I have some old rack boxes which are going to get some bigger harddrives (IDE/ATA, not SATA) in Spring and I'm wondering if I should put two disks in them and use them as RAID 1 (software RAID). Objective being that the machine can hopefully carry on after (one) disk failure (including rebooting). I don't have any experience with software RAID. Can I do this during the normal CentOS (4) setup or can I even do this later (when there's only one disk and I add another one)? Does it make a difference performance-wise? (slight drop?) Is it reliable, so that it will fulfill on the purpose or should I better forget it? (Replacing the mainboards or adding RAID controller cards is out of the question.) I'm certainly willing to read a How-To or other documentation, but since it's completely new to me I'm not really sure where to start searching. Kai -- Kai Schätzl, Berlin, Germany
