SuperMicro with LSI MegaRaid with Centos 6.0
by Gregory P. Ennis 21 May '13

21 May '13

Everyone, I am trying to install a Centos 6.0 system on a SuperMicro with an LSI MegaRaid SCSI 320-2 controller. I had originally tried to install 6.4, but the 6.4 install DVD does not boot with this configuration. See : http://bugs.centos.org/view.php?id=5377 Fortunately, the 6.0 install DVD worked fine until it failed to identify the hard disc controller. I checked the lsi.com site which had a driver for RH 3 and RH4, but not 5 and not 6. The interesting thing about this machine is that I had Centos 5.0 installed without difficulty (that over time upgraded to 5.9) Does anyone have any idea of a driver I could use to get Centos 6.0 up and running. Thanks!!!! Greg Ennis

Force anaconda to use GPT labels on all drives?
by Tucker 21 May '13

21 May '13

I did a quick search through the archive and couldn't find anything that mapped to my need, so I figured I should ping the community and see if anyone has the requisite knowledge and could point me in the right direction. *Succinct Version* Is there a way to, using updates.img, monkey patching or swapping in a newer Anaconda (>= 16) to force all disks to have gpt labels and not just disks> 2TB? *TL;DR Version* I'm working on setting up an installation environment and am trying to make it as machine agnostic as possible. We're currently using CentOS 6.3 (will start 6.4 work soon). Getting software on a machine is simple but laying out disks is less so. Some of our machines have eight disks and some twelve and some others have two. Normenpoughaalizing on a single hardware profile is not an option, due to the various types of systems we need. What I'm currently having to do is wipe the partition information and set a gpt label, in a %pre section, on the first two disks only. After that, I have to use our post installation installer to create the partitions on the remaining disks. Because of the way it works, unless we manually remove the partitions from the remaining partitions, prior to doing the post installation steps (which setup the host for its role), we will end up with drives that have old information (read as: not formatted). I understand that that normal way to do this is to use zerombr and clearpart but this leaves me with some disks that have msdos labels (<= 2TB) and some with gpt labels (> 2TB). In order to simplify everything, without having to be deterministic about hardware type, we need to use gpt labels on everything. It appears that Anaconda 16 and beyond use gpt labels by default (unless "nogpt" is provided as a kernel option) but CentOS (even 6.4) is using Anaconda 13. I've read about updates.img but I'm not sure that's the solution (if so, I don't grok it yet). I've managed to get Anaconda 17 to build from source (wow... that was "fun") but don't know enough kickstart/anaconda to know how and if I can swap that in place of the existing Anaconda images and still get CentOS to install. -- --tucker

ReiserFS - status?
by Rafał Radecki 21 May '13

21 May '13

Hi All. What is the status of ReiserFS in CentOS at the moment? I have some servers which use it as a loadable kernel module. I am thinking about a filesystem for database systems and would like to know if ReiserFS will be maintained in CentOS/Linux kernel in the future? Best regards, Rafal.

ICMPv6 Neighbour Solication request is not answered by linux when IPv6 address is assigned via Netlink code.
by Kevin Peterson 21 May '13

21 May '13

Hi, I have a process which is running as a linux service and assigns IP addresses using netlink to configued interface in linux. For IPv4 addresses i do not see any issue with this assignment. When i try to assign an IPv6 address, the address gets assigned successfully to the interface, but the Neighbour Solication request received for that address is not responded with and hence ping6 from a different machine doesn't work. When i take the same netlink code and run it in a sample program the address gets assigned and the Neighbour solicitation is responded with a advertisement and hence ping6 works. IP assigned by the program : 7000::15/32 IP on client machine from where ping6 is done : 7000::17/32. Bot machines are connected to same Layer-2 switch. I have flushed the ip6tables on both the machines just to rule out any firewall issues. Thanks, Kevin Peterson

semi-OT: flashing the BIOS on an HP dl580 GT, afterward
by m.roth＠5-cent.us 21 May '13

21 May '13

When last we saw our hero, er, sysadmin, he'd found that the "noarch" BIOS update was, in fact, a self-extracting .exe file, and he'd extracted it. Finally getting the ok to take the system down, the following hilarity (for small values of hilarity) ensued. First, booting off unetbootin to freedos was fine... except it was try to guess which version - freedos + emm386 + himem, no himem, live CD only, or, finally, "no drivers loaded", which works. It gags on something orders of magnitude larger than it was written for, y'know. Then I discover that the builtin type command does *not* have /p, and there's no more command, and I should have read the longer files before I started this. Fun with <ctrl-s> ensues. Finally, I find what are actually DOS config.sys files, with different extensions, and read them - they're one-liners, and find out how to run the rompaq.exe that runs the utility to flash the drives, and run it. And again. And again. And *finally* get the reason it's failing, and (to save the original name) copied the actual data from an 8.3 name into 7 char, which the utility demands: *exactly* seven chars, no more, no less. And unlike the Dell utility, which give you lots of warm fuzzies ("collecting data", "this is for this hardware, this is newer, do you want to update?"), this just does it. Fortunately, this HBS contains a backup ROM, just in case.... And a three-finger kill later, it's up. And I put the memory boards back in, so we'll see if the BIOS update fixed the memory problems (remember them? this song's about them).... mark

security breach - ftp?
by Philipp Duffner 21 May '13

21 May '13

Hi, I'm running Plesk 11.0.9 on a Centos 5.5. A website on that box got hacked last week and malicious code got inserted into some html/php files. So I went to find out what happened... I found no back doors by using rkhunter or manually searching for suspicious files in /tmp, etc. No activity at all in the php logs at the time of the attack. I also analysed of course the system logs (messages, secure, ...) - nothing that I could see either - except for an entry of an successful login to that domain via FTP just before the the modified dates of the infected files. I found one of the oldest infected files were in the folder of a hopelessly outdated version of a WYSIWYG editor and decided to blame that due to probability. So in order to recover I did in this order... * delete httpdocs from the website * change the FTP password * upgrade and update Plesk from 10.0.4 to 11.0.9 * upgrade php to php53 via plesk - this also updates mysql and phpmyadmin * yum update everything, also made sure I have the latest version of proftp * restore the entire website from a clean backup * delete the WYSIWYG folder that I believed had caused the vulnerability The next days I slept ok hoping I removed the attacker's entry point(s). ...so I thought! Today the website got hacked again - the same exploit on the pages, meaning same attacker. And again I can see nothing suspicious except for the successful FTP logon just before the modification time of the infected html/php: 2013-05-18T15:01:25.195559-07:00 MyServer proftpd: Deprecated pam_stack module called from service "proftpd" 2013-05-18T15:01:25.204731-07:00 MyServer proftpd: Deprecated pam_stack module called from service "proftpd" 2013-05-18T15:01:25.204831-07:00 MyServer proftpd: Deprecated pam_stack module called from service "proftpd" 2013-05-18T15:01:25.205183-07:00 MyServer proftpd: pam_unix(proftpd:session): session opened for user WEBSITEUSER by (uid=0) 2013-05-18T15:01:25.205244-07:00 MyServer proftpd: Deprecated pam_stack module called from service "proftpd" 2013-05-18T15:01:25.231034-07:00 MyServer proftpd[20243]: 127.0.0.1 (188.190.126.105[188.190.126.105]) - USER WEBSITEUSER: Login successful. 2013-05-18T15:04:08.095351-07:00 MyServer proftpd: Deprecated pam_stack module called from service "proftpd" 2013-05-18T15:04:08.095379-07:00 MyServer proftpd: pam_env(proftpd:setcred): Unable to open config file: /etc/security/pam_env.conf: No such file or directory 2013-05-18T15:04:08.095445-07:00 MyServer proftpd: Deprecated pam_stack module called from service "proftpd" 2013-05-18T15:04:08.095455-07:00 MyServer proftpd: pam_succeed_if(proftpd:session): error retrieving information about user 0 2013-05-18T15:04:08.095463-07:00 MyServer proftpd: pam_unix(proftpd:session): session closed for user WEBSITEUSER I know for a fact it couldn't have been the website owner because I didn't give him the new FTP password yet. # yum list | grep proftp psa-proftpd.i386 1.3.4a-cos5.build110121114.13 installed proftpd.i386 1.3.3g-2.el5 epel proftpd-ldap.i386 1.3.3g-2.el5 epel proftpd-mysql.i386 1.3.3g-2.el5 epel proftpd-postgresql.i386 1.3.3g-2.el5 epel I think I really hit a snag with this one - I have no idea where to go forward from here.

NIC interrupts and packets per second ratio, how to calculate? There must be some way...
by Alex Flex 21 May '13

21 May '13

Hello again guys, Iam trying to asses the best hardware for a machine that procceses a high number of packets per second on its NIC. THe only way I can achieve this without guesses is If iam able to understand or test what the number of interrupts available per core and how to translate that to PPS capabilities. So far ive been testing an Core I5 CPU and was able to achieve up to 400k packets (small syn packets) in a single core (2.8Ghz i think..) untill the point where 100% was reported to serve as hardware interrupts, yet what is the math behind this? In any case, i find this rather low and confused as I know for a fact that small home routers even on gigabit have specs that detail they can do packet forwarding at rates up to 1.4 million pps and iam sure there CPU is no where as powerfull as a 2.8Ghz Core I5 core. Any orientation is much appreciated. Alex

6.4 on old PC not connecting
by Beartooth 20 May '13

20 May '13

On an old server (Dell PowerEdge SC1420, now without RAID) I have CentOS 6.4 installed, up, and running -- but it keeps failing to connect for some reason .... NetworkManager applet 0.8.1 runs blue rings around in the panel for a while, then reports itself disconnected. It also offers a pseudo-choice, if I right-click, between Wired Connection and eth0; in fact, the cable to the router is the only connection the machine has or has ever had. I've tried such things as I could find to get a connection, in vain. I've tried replacing the cable. If there's a good fix, I'd like to get my wife running CentOS, because it's one obvious choice for her to have against such time as I'm gone. (I don't at all claim to be the Oldest Subscriber, but I am at an age such that I would be irrational not to plan for such contingencies.) What new way can I try to get this beast online? -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User Remember I have precious (very precious!) little idea where up is.
