Recompiling the Kernel for CentOS 6.5
by Saket Sinha 29 Mar '14

29 Mar '14

Hi, I am working on CentOS 6.5 which has 2.6.32-431 kernel. I have a problem with my driver and I need to enable Kernel-Memory leak in the kernel for which I will have to recompile the kernel. I get the kernel source tree from the the source rpm for my running kernel from below link- http://vault.centos.org/6.5/updates/Source/SPackages/kernel-2.6.32-431.11.2… and I try to build the kernel according to the doc link written for RHEL-3 - http://www.centos.org/docs/rhel-sag-en-3/s1-custom-kernel-modularized.html according to which it tells me , after make menuconfig( and customizing my configuration), I need to follow the following steps- 1. make bzImage 2. make modules 3. make modules_install 4. make install but I get errors in the first step only-(make bzImage) It was pointed out the CentOS-devel mailing list the below link- http://wiki.centos.org/HowTos/Custom_Kernel which allows me to create a rpm for my customized kernel and install it. Now my question is there no method where in I can apply a kernel source tree from kernel.org(maybe 3,x version) and install it on Centos ? Regards, Saket Sinha

How to configure
by Obono I. O 29 Mar '14

29 Mar '14

Please I am new to Centos Linux and need direction on how to configure the following How to configure Linux server on VMWARE and statically assigned an IP address in the segment 192.168.13.0/24 with the Windows client being able to communicate with the server. A DHCP server should be running on your Linux box leasing addresses to the local segment. SETUP A DNS name resolution system for resolving addresses. The DNS server must perform forward and reverse lookup operations. Name resolution should be configured to use the above IP addresses and not the localhost (127.0.0.1). Implement a Nagios Network Monitoring system in on the Linux server and demonstrate the complete monitoring of all the services running on the server. In addition, Nagios should be configured to support adaptive and performance data monitoring to both the server and the client in the test network. Client is windows xp Thank you

Static IPv6 configuration
by Robert Moskowitz 29 Mar '14

29 Mar '14

system-config-network seems to only set IPv4 addresses. There does not seem to be any tool for IPv6 addresses? I know I can always edit /etc/sysconfig/network-scripts/ifcfg-eth0 but is there a 'tool' for it?

High load average, low CPU utilization
by Matt Garman 28 Mar '14

28 Mar '14

I have a dual Xeon 5130 (four total CPUs) server running CentOS 5.7. Approximately every 17 hours, the load on this server slowly creeps up until it hits 20, then slowly goes back down. The most recent example started around 2:00am this morning. Outside of these weird times, the load never exceeds 2.0 (and in fact spends the overwhelming majority of its time at 1.0). So this morning, a few data points: - 2:06 to 2:07 load increased from 1.0 to 2.0 - At 2:09 it hit 4.0 - At 2:10 it hit 5.34 - At 2:16 it hit 10.02 - At 2:17 it hit 11.0 - At 2:24 it hit 17.0 - At 2:27 it hit 19.0 and stayed here +/1 1.0 until - At 2:48 it was 18.96 and looks like it started to go down (very slowly) - At 2:57 it was 17.84 - At 3:05 it was 16.76 - At 3:16 it was 15.03 - At 3:27 it was 9.3 - At 3:39 it was 4.08 - At 3:44 it was 1.92, and stayed under 2.0 from there on This is the 1m load average by the way (i.e. first number in /proc/loadavg, given by top, uptime, etc). Running top while this occurs shows very little CPU usage. It seems the standard cause of this is processes in a "d" state, which means waiting on I/O. But we're not seeing this. In fact, I the system runs sar, and I've collected copious amounts of data. But I don't see anything that jumps out that correlates with these events. I.e., no surges in disk IO, disk read/write bytes, network traffic, etc. The system *never* uses any swap. I also used "dstat" to collect all data that it can for 24 hours (so it captured one of these events). I used 1 second samples, loaded the info up into a huge spreadsheet, but again, didn't see any obvious "trigger" or interesting stuff going on while the load spiked. All the programs running on the system seem to work fine while this is happening... but it triggers all kinds of monitoring alerts which is annoying. We've been collecting data too, and as I said above, seems to happen every 17 hours. I checked all our cron jobs, and nothing jumped out as an obvious culprit. Anyone seen anything like this? Any thoughts or ideas? Thanks, Matt

Linux malware attack
by Timothy Murphy 28 Mar '14

28 Mar '14

SlashDot had an article today on a Linux server malware attack, <http://it.slashdot.org/story/14/03/18/2218237/malware-attack-infected-25000…>. I wonder if there is a simple test to see if a CentOS machine has been infected in this way? The article mentions Yara and Snort rules to test for this, but I wonder if there is something simpler? Alternatively, are there Yara or Snort packages for CentOS? ("Yum search" didn't seem to find anything.) -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Mail server - MailScanner/Baruwa/postfix/...
by Rafał Radecki 28 Mar '14

28 Mar '14

Hi All ;) Currently I am gathering info about possible components for a mailserver. I think that MailScanner/Baruwa/postfix will be a good choice. I set up a similar system (with MailWatch instead of Baruwa) about 3 years ago and had very good experience ;) What do you think about MailScanner/Baruwa now? Do you maybe use any good alternatives and can recommend them? Thanks for all help ;) Best regards, Rafal.
