Custom respin ISO prompting for discs
by Karl MacMillan 03 Jun '14

03 Jun '14

I'm creating a custom install / respin ISO with updated packages and a kickstart - starting from CentOS 6.5 minimal install DVD. I'm generally following the directions from http://smorgasbork.com/component/content/article/35-linux/128-building-a-cu… . I can create the iso, boot, have it find the installation media (it prints "Found local installation media"), partition the disks, resolve the dependencies, and then when it gets to "Starting installation" it prompts with "Please insert CentOS disc 1 to continue". Debugging I've done so far (all but 4 result in the prompt for disc 1): 1. I've verified that the package set I have resolves all dependencies by testing the installation into a new rpmdb. 2. I've copied over the minimal install DVD contents directly, placed comps.xml in the Packages directory, and recreated repodata (using 'createrepo -g Packages/comps.xml -o . Packages/"). 3. Built on both CentOS 6.5 (with all updates) and Fedora 20. 4. Also tried to minimal DVD _without_ running createrepo (just placed the kickstart in the root of the image). This worked fine. That 4 works suggest that createrepo is at fault, but I can't for the life of me figure out what is going on. I've done this without a base url (-u) and with (using 'head -1 .discinfo). Can anyone offer some suggestions for how to debug further? Thanks - Karl

nodejs, epel, SCL
by Eugene Vilensky 02 Jun '14

Hello, With SCL and epel repositories enabled, some dependencies for the package name 'nodejs' get satisfied with libs from SCL which are placed in paths that are not part of my user's environment. Is there a method to make sure that nodeJS from epel dependencies are only satisfied from epel? For example, the http parser dependency gets satisfied by nodejs010-http-parser-2.0-5.20121128gitcd01361.el6.centos.alt.x86_6 http-parser-2.0-4.20121128gitcd01361.el6.x86_64 : HTTP request/response parser for C Repo : epel Matched from: Filename : /usr/lib64/libhttp_parser.so.2 Other : libhttp_parser.so.2()(64bit) Filename : /usr/lib64/libhttp_parser.so.2.0 http-parser-2.0-4.20121128gitcd01361.el6.i686 : HTTP request/response parser for C Repo : epel Matched from: Other : libhttp_parser.so.2 Filename : /usr/lib/libhttp_parser.so.2 Filename : /usr/lib/libhttp_parser.so.2.0 nodejs010-http-parser-2.0-5.20121128gitcd01361.el6.centos.alt.x86_64 : HTTP request/response parser for C Repo : scl Matched from: Filename : /opt/rh/nodejs010/root/usr/lib64/libhttp_parser.so.2 Filename : /opt/rh/nodejs010/root/usr/lib64/libhttp_parser.so.2.0 Other : libhttp_parser.so.2()(64bit)

traffic distribution not happening in centos 6.5
by Varun Sharma 02 Jun '14

02 Jun '14

Hi, I am experimenting with libnetfilter_queue. libnetfilter_queue is a userspace library providing an API to packets that have been queued by the kernel packet filter. I am using sample code(nfqnl_test.c) available on netfilter.org. I have generated two binaries (queue0 and queue1) using that nfqnl_test.c sample code. These binaries are working as per expected behaviour in case of Centos 6.2 but with Centos 6.5 only one queue is receiving network traffic. I am not able to understand why only one queue is receiving network traffic in case of Centos 6.5 whereas same network traffic is being distributed in both the queues with Centos 6.2. uname –a :- Linux hwcentos8 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Machine Info: 16 core machine with 64GB RAM. Command used for iptables in Centos 6.5 :- iptables -A INPUT -j NFQUEUE --queue-balance 0:1 Output In Centos 6.5 :- [varun@exp2 ~]$ ./queue0 opening library handle unbinding existing nf_queue handler for AF_INET (if any) binding nfnetlink_queue as nf_queue handler for AF_INET binding this socket to queue '0' setting copy_packet mode pkt received queue0 hw_protocol=0x0800 hook=1 id=0 hw_src_addr=fc:4d:d4:d3:7f:73 indev=2 payload_len=40 entering callback pkt received queue0 hw_protocol=0x0800 hook=1 id=1 hw_src_addr=fc:4d:d4:d3:7f:73 indev=2 payload_len=40 entering callback pkt received queue0 hw_protocol=0x0800 hook=1 id=2 hw_src_addr=fc:4d:d4:d3:7f:73 indev=2 payload_len=40 entering callback pkt received queue0 hw_protocol=0x0800 hook=1 id=3 hw_src_addr=fc:4d:d4:f1:e1:5f indev=2 payload_len=78 entering callback [varun@exp2 ~]$ ./queue1 opening library handle unbinding existing nf_queue handler for AF_INET (if any) binding nfnetlink_queue as nf_queue handler for AF_INET binding this socket to queue '1' setting copy_packet mode Please let me know if more information is required.

CentOS 6 KVM networking: What am I missing???

OK, I have a strange problem. It is probably something simple/stupid, but I cannot figure it out. I have a nice new PowerEdge T20 that I installed CentOS 6 (6.5) on with Virtualization (KVM).

Hi, I am using centos 6.4. i am trying to update /proc/sys/fs/epoll/max_user_instances but it seems like it is not supported anymore in /etc/sysctl.conf. How do we update max_user_instances on centos 6.4? Thanks & Regards Manjunath

"new" computers and monitors
by Michael Hennebry 30 May '14

30 May '14

Until recently, I had a 32-bit machine with one monitor running fedora. The later editions of fedora didn't like it, so I switched to CentOS. Now I have two 64-bit machines and two monitors and a CenturyLink router. Also a KVM switch that I have not taken out of the package. My main machine has two video connections and two ethernet connections, eth0 and eth1 . I've never had more than one machine or more than one monitor before. I'd like to be able to use both monitors at once on my main machine. I'd like to be able to switch one monitor between machines without too much trouble. I'd rather not where the pins out. KVM will do this, right? KVM is transparent to the computer, right? My secondary machine sometimes runs Windows, so I'd like it not to have its own global IP address. My first thought would be to connect it directly to one of the ethernet ports on my main machine. How do I go about this? The answer I am expecting is one or more links to tutorials or the like. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "SCSI is NOT magic.

OEM suggestions
by m.roth＠5-cent.us 30 May '14

30 May '14

Hey, folks, I'm working on finding some new compute nodes. What I'm looking for is a 64 core box, with room enough for a lot of RAM. I can get it from Dell, or HP (bleah! a 4U box), but I need to have three quotes, y'know. We've gotten a lot from Penguin in the past, but they're all Supermicro, and we've had a *lot* of problems with the 64 core boxes, so I'm looking for another vendor. Suggestions? Recommendations? People to run the other way from? (Sun/Oracle is down there *under* "none of the above"). mark
