Memcache timeouts?
by Rafał Radecki 22 Mar '13

22 Mar '13

Hi All. I am currently using memcache daemon in version 1.4.15 on one of my servers. The second one is executing php scripts which use mentioned memcache daemon (php53-pecl-memcache-2.2.5). Memcache server: CentOS release 6.3 (Final) 2.6.32-279.5.2.el6.centos.plus.x86_64 uptime 184 days PHP server: CentOS release 6.3 (Final) 2.6.32-279.19.1.el6.centos.plus.x86_64 uptime 43 days The memcache server gets about: - 250Mb/s traffic - 4500 connections/s On PHP server I get sometimes timeouts, ~20-30 daily. Both servers are not swapping, they have free memory, cpu is ~40% used max. But I have found some errors in netstat -s: Memcache server: TCP 7251 failed connection attempts (incrementing) 56447 connection resets received (incrementing) TcpExt 36 packets pruned from receive queue because of socket buffer overrun (not incrementing) 2820 packets collapsed in receive queue due to low socket buffer (not incrementing) 459479 connections reset due to unexpected data (incrementing) PHP server: TCP 540 failed connection attempts (incrementing) 381066 connection resets received (incrementing) TcpExt 7194 packets pruned from receive queue because of socket buffer overrun (incrementing) 250104 packets collapsed in receive queue due to low socket buffer (incrementing) 2447931 connections reset due to unexpected data (incrementing) I have tuned tcp/ip a bit: net.ipv4.tcp_fin_timeout = 5 net.ipv4.tcp_tw_reuse = 1 net.core.somaxconn = 1024 net.ipv4.tcp_max_syn_backlog = 4196 net.core.netdev_max_backlog = 4196 net.ipv4.tcp_sack = 0 net.ipv4.ip_local_port_range = 8192 65534 net.core.rmem_max = 8388608 net.core.wmem_max = 8388608 net.ipv4.tcp_rmem = 4096 65536 8388608 net.ipv4.tcp_wmem = 4096 65536 8388608 and set txqueuelen for interfaces (1Gb/s) to 5000. but where to look next? May it be so that the php client version is buggy? Any other tips? Best regards, Rafal.

CentOS 6.x
by Kaushal Shriyan 22 Mar '13

22 Mar '13

Hi Please help me understand to choose between the two versions CentOS 6.3 and CentOS 6.4. I am not sure to choose 6.4 since it is being released recently( http://lists.centos.org/pipermail/centos-announce/2013-March/019276.html) and it may be risky to push it in Live environment. Regards, Kaushal

Ctrl-Alt-F? bindings broken under xen 3.0.3-142.el5_9.1 / 2.6.18-348.1.1.el5xen?
by Robert Heller 22 Mar '13

22 Mar '13

I am not sure what I did, but for some reason Ctrl-Alt-F? bindings are broken on 64-bit xen desktop machine (but not on my laptop (32-bit, no xen)). Both machines are (mostly) up-to-date and running CentOS 5.9. I rarely hop to different Virtual Consoles (eg Ctrl-Alt-F1 ... Ctrl-Alt-F7), but today I wanted to go to the main console to watch some kernel verbage (I was checking something with hot-swap SATA disk). I discovered that I could not switch back to my X11 session (Ctrl-Alt-F7)! I did some googling, but did not find anything. So far as I can tell, I can switch to one of the other VT (Ctrl-Alt-Fn) *from* VT7 (my X11 session), but cannot then switch to any other VT from there, using the Ctrl-Alt-F? key bindings. The chvt command works, but the keybindings don't. It is most strange. I know this used to work (and still does work just fine on my laptop, running much the same system, including the same X11 configuration, with the same desktop setup (plain fvwm in MWM compatibity mode, same keybindings, etc.). Other than different video cards (and thus different X11 drivers) and 32-bit vs 64-bit and with xen virtualization on the 64-bit desktop box, the system setups are virtually identical. -- Robert Heller -- 978-544-6933 / heller(a)deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments

CentOS 6.4 x86_64 VM Install freezes
by Robert Heller 21 Mar '13

21 Mar '13

I am trying to install a CentOS 6.4 x86_64 VM using a CentOS 5.9 x86_64 host, but its install has froze *twice*. What I am doing is to create a 10gig LVM volume, which I put a MS-DOS partition table on (using fdisk). I then format the only partition to ext3, install grub and install the pxeboot kernel and initrd.img and a simple grub.conf to load this. I have the CentOS 6.4 x86_64 ISOs mounted (via loop) and exported as NFS file systems: /distrocds/CentOS/6.4/CentOS-6.4-i386-bin-DVD1.iso 3.6G 3.6G 0 100% /centos64i386/1 /distrocds/CentOS/6.4/CentOS-6.4-i386-bin-DVD2.iso 1.1G 1.1G 0 100% /centos64i386/2 /distrocds/CentOS/6.4/CentOS-6.4-x86_64-bin-DVD1.iso 4.1G 4.1G 0 100% /centos64x86_64/1 /distrocds/CentOS/6.4/CentOS-6.4-x86_64-bin-DVD2.iso 1.4G 1.4G 0 100% /centos64x86_64/2 sauron.deepsoft.com% sudo exportfs /centos64x86_64/1 192.168.250.0/255.255.255.0 /centos64x86_64/2 192.168.250.0/255.255.255.0 /centos64i386/1 192.168.250.0/255.255.255.0 /centos64i386/2 192.168.250.0/255.255.255.0 I am able to boot up the installer and have it NFS mount the first DVD and things go fine util it installs selinux-policy-targeted-3.7.19-195.el6.noarch. The VM is busy for a while, then the CPU usage goes to zero and it just sits there. What am I doing wrong? This worked just fine with the 32-bit version of CentOS 6.4. Is it because some package from the second disk is needed? Do I have to create a merged version of the DVDs? Or is something else wrong? Screenshot available here: http://www.deepsoft.com/wp-content/uploads/2013/03/FrozenInstallx86_64.png And the VM's defination is here: http://www.deepsoft.com/wp-content/uploads/2013/03/c664guest.xml -- Robert Heller -- 978-544-6933 / heller(a)deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments

dhcpd options
by m.roth＠5-cent.us 21 Mar '13

21 Mar '13

A few weeks ago, suddenly, reading news at lunch, I could not get to nytimes.com. I could ping it, and nslookup it, and if I put the IP address in place of the name, it was fine. After *much* back and forth over a ticket I put in, over the last week or so, our group figured it out: It *seemed* to be related to IPv6, and there's only *some* few sites, such as the Times, and Orbits, and one or two others I found, while, say, the Washington Post, or Huffpo, etc, were fine; and I could make it work by putting IPV6INIT="no" in ifcfg-eth0 and restarting the network, but another admin got it nailed, we *think*: apparently the M$-based DNS resolver's sending back extended DNS packets, and we gag. tcpdump saw us asking for an A record, then an AAAA record, then using search.... But putting the *very* counterintuitive option edns0 in /etc/resolv.conf, it works instantly, no caching, no nuthin'. Taking that out breaks it again. My question: it *appears* that we could add option edns0 to dhcpd.conf on the server, and it would fix it for everyone on our subnet. Have I misunderstood what I'm reading in the manpages? mark

Is it fine to upgrade to Centos 6 rpms, being at centos 5.8
by Anumeha Prasad 21 Mar '13

21 Mar '13

Hi, I'm currently at CentOS 5.8. After some penetration testing, found some high severity OpenSSH issues which would require its upgrade. But till CentOS 5.9 the latest rpm available is openssh-4.3p2-82.el5 (which I'm currently using). Is it fine to upgrade to CentOS 6 rpms while I'm on CentOS 5? Thanks, Anumeha

GFS2 hangs after one node going down
by Maurizio Giungato 21 Mar '13

21 Mar '13

Hi guys, my goal is to create a reliable virtualization environment using CentOS 6.4 and KVM, I've three nodes and a clustered GFS2. The enviroment is up and working, but I'm worry for the reliability, if I turn the network interface down on one node to simulate a crash (for example on the node "node6.blade"): 1) GFS2 hangs (processes go in D state) until node6.blade get fenced 2) not only node6.blade get fenced, but also node5.blade! Help me to save my last neurons! Thanks Maurizio

by Austin Einter 21 Mar '13

21 Mar '13

Dear All I had successfully installed posfixadmin. I was able to login to postfix admin and create email ids etc. In something broken (not sure which one caused the issue), I am experiencing below problem with postfix admin. 1. I am able to access domain/mailadmin page. 2. I can create admin accounts at domain/mailadmin/setup.php 3. I can see the admin login page by access But when I enter my admin mailid, and password (i am 100% sure these are correct), it goes to a page domain/login.php and then says "Page not found". My question is why it is redirecting wrongly to domain/login.php. Kindly help me. Please note that I have all other things working like amavisd, dovecot etc, I am able to send recv mails for accounts that I created previously. Regards Austin
