zip alternative?
by Jordi Espasa Clofent 02 Jan '07

02 Jan '07

Hi, Recently I've got several errors in one of my backups systems. The backup system uses basic tools: rsync, mysqldump, and zip and have worked fine until a few days ago. The zip command shows an error like this: size limit exceeded. So I've found out an alernative : p7zip. It seems to has all the needed features: * available package (in Dag's repo) * 64 bits for size (http://sourceforge.net/forum/message.php?msg_id=3031109) * support several compression format ¿What do you know about this tool? TIA. -- Jordi Espasa Clofent PGP id 0xC5ABA76A #http://pgp.mit.edu/ FSF Associate Member id 4281 #http://www.fsf.org/

RE: [CentOS] disabling prelink?

This document may be helpful. http://people.redhat.com/jakub/prelink.pdf Regards, Justin. -----Original Message----- From: Aleksandar Milivojevic [mailto:alex@milivojevic.org] Sent: Tuesday, January 02, 2007 11:14 AM To: CentOS mailing list Subject: [CentOS] disabling prelink? What are the pros and cons of disabling prelinking in CentOS 4? From what I understand, prelinking is ment to be performance improvement (faster loading time for binaries). I can see some potential benefit on workstations where many different processes are started frequently. But how big is that benefit in real life? Would I slow down things noticably if there is no prelinking? Is there any benefit at all of having prelinking on a server box that runs couple of daemons which are started only at boot time, and then they either use threads or fork themself to handle requests? In either case, such processes are fully (or at least mostly) linked at boot time. For example servers running stuff like Sendmail or Postfix, Dovecot or Cyrus-IMAPD, Squid, MySQL, LDAP and such. _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

Platform independent solution to watch "Streaming Service of the Council of the European Union.
by Michel Daggelinckx 01 Jan '07

01 Jan '07

"The Council of the EU has a streaming service so that we can watch its meetings ? but the service can only be accessed by Mac or MS Windows users. This is because they employ WMV format for the videos. In the FAQ they express a really strange opinion about this: 'The live streaming media service of the Council of the European Union can be viewed on Microsoft Windows and Macintosh platforms. We cannot support Linux in a legal way. So the answer is: No support for Linux.' An online petition has been set up to create pressure to convince the EU council to change its service to one that is platform independent." (slashdot) http://www.petitionspot.com/petitions/eu_streaming_service_for_everybody You are free to sign the petition. -- Video games don't affect kids, I mean if Pac Man affected us as kids, we'd all run around in a darkened room munching pills and listening to repetitive music. - Kristian Wilson, CEO at Nintendo Gaming Corporation Inc.

I found an old ROM BIOS chip in my drawer with label Centos(r) Copyright 1994 on it. Then I found http://www.centos.com.tw/ on the net. Has anyone checked if you can use the name centos without any fear of litigation?

CentOS 4.4 e1000 and wire-speed
by Ross S. W. Walker 31 Dec '06

31 Dec '06

Currently I'm running CentOS 4.4 on a Dell Poweredge 850 with an Intel Pro/1000 Quad-port adapter. I seem to be able to only achieve 80% utilization on the adapter, while on the same box running Fedora Core 5 I was able to reach 99% utilization. I am using iSCSI Enterprise Target as my application and I am using the nullio feature, it just discards any write and sends back random data for any read, for my bandwidth test. The IO pattern I use is 1MB block sequentials. Is there something in the OS that is throttling the bandwidth as it seems to be capped at 80%. I have selinux and iptables disabled, and I have tuned the TCP/IP stack to mimic the settings under 2.6.17, except bumped up the default IP send/receiver buffer size for improved UDP transmission over 1Gbps. The CPU is a P4 Dual Core 3GHz, not top of the line but adequate for my needs (strictly block io). Here are the TCP/IP tunables from my sysctl.conf: # Controls default receive buffer size (bytes) net.core.rmem_default = 262144 # Controls IP default send buffer size (bytes) net.core.wmem_default = 262144 # Controls IP maximum receive buffer size (bytes) net.core.rmem_max = 262144 # Controls IP maximum send buffer size (bytes) net.core.wmem_max = 262144 # Controls TCP memory utilization (pages) net.ipv4.tcp_mem = 49152 65536 98304 # Controls TCP sliding receive window buffer (bytes) net.ipv4.tcp_rmem = 4096 87380 16777216 # Controls TCP sliding send window buffer (bytes) net.ipv4.tcp_wmem = 4096 65536 16777216 Ross S.
