Moving the Home dir to new server
by Todd Cary 28 Feb '07

28 Feb '07

I have a new Centos installation that has an empty /home dir and there are no users...just root. I want to move the home directory from another server to the new one. At this time the old /home directory has been tarred with "-prf". That will keep permissions which could be a problem. Is there a simple way to move the /home directory? And the non-system users in the password and group files? Todd -- Ariste Software 200 D Street Ext Petaluma, CA 94952 (707) 773-4523

firefox 2.0
by Jerry Geis 02 Feb '07

02 Feb '07

Has anyone downloaded firefox 2.0 and tried it? I just did. I am very confused. I download the firefox-2.0.tar.gz Untared it and the readme.txt was one sentence. nothing useful. There is no install**** anything. The URL the readme.txt mentions to the release notes, does have a "install" link, but it doesnt say anything about actually installing. All it says in one sentence is "install firefox 2 will overwrite your existing install". I am stuck.... Has anyone else installed firefox 2 and can share. I know there is seamonkey now but it is broken for the functionality I need. I was hoping it is fixed in firefox 2.0. Thanks, Jerry

nscd crashes
by Josh Kelley 25 Jan '07

25 Jan '07

I've had problems with nscd crashing every few days on my CentOS 4 mail server for a while now. The problems started maybe around CentOS 4.2, although I don't remember for sure. My debugging efforts let me to disable nscd's persistent cache, and that seemed to work for a while, but since upgrading to CentOS 4.4, the crashes have started again. When nscd crashes, the rest of the system becomes unreliable. Dovecot hangs when new users attempt to log in (fixed or worked around by switching Dovecot versions), and MIMEDefang (which we use for mail filtering) starts failing when it tries to process mail. A bit more information about our configuration: We use nss_ldap and pam_ldap against a failover pair of Fedora Directory Servers. nscd is also crashing on another of our servers (a fileserver) but with less regularlity; on our other servers, it works fine, even without disabling the persistent cache. Has anyone seen similar problems with nscd? Any tips for debugging it? I can use gdb, strace, etc. if I have to, but that can be time consuming, and it's hard to take the time to do that when people are yelling about the mail server being down. (Does CentOS provide debuginfo RPMs?) Thanks. Josh Kelley

nfsv4 in centos?
by R Lists06 12 Jan '07

12 Jan '07

Greetings Some time ago I briefly played with NFS. More recently with Samba. What I am wondering is if NFSv4 is already integrated into Centos 4 from upstream. Reference: http://www.linuxplanet.com/linuxplanet/reviews/6331/1/ if not, is there a timeline? Centos 5 ? and... is or can NFS be a compatible yet better replacement for Samba? thanks - rh -- Robert - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

UPS support on CentOS 4.4
by Edward Diener 06 Jan '07

06 Jan '07

I have an APC Back-UPS XS1500 powering my computer. It may be overkill for a single computer but it makes me feel secure. Gnome power management will not install on CentOS 4.4 because of dependency problems. I have installed the acpupsd daemon and this will protect me against power failure but the GUI interface to it, gapcmon, will not install due to dependency problems. I know that some will not consider a GUI interface important but I like to see what is happening if and when my A/C power gets disconnected and my computer is running on UPS battery power, and I like to be informed of this when I am online. Without gapcmon, or trying to hack my own program, this is not possible with CentOS 4.4, although as I said the apcupsd daemon will automatically and gracefully shut me down if my A/C power goes off and my UPS gets close to running out of backup battery power.. I realize that CentOS 4.4 is based on reliability, and not the latest and greatest software out there, but I am wondering what total UPS solution actually exists for it, or for RHEL4 which customers of the latter have used. I can live with apcupsd, and I realize that with an upcoming CentOS 5 there will probably be better compatibility, but I was wondering if there is any other total solution for the time being which anyone else has used. Thanks !

tftp times out
by Mark Snyder 03 Jan '07

03 Jan '07

tftp keeps timing out when I try to transfer files. I intend to use tftp with G4U to clone a standard workstation. I am testing it between two Dell poweredge servers running CentOS 4.3. "chkconfig --list |grep tftp" shows tftp up and running on both boxes. When connected "tftp>status" shows it is talking to the other box "tptp>trace" shows "sent WRQ <file=slavelit, mode=netascii>" and ends with Transfer timed out. I have tftp is being run under xinetd. I have modified /etc/xinetd.d/tftpd as follows: server_args -p -c -U 002 -u install -s /tster I have setup a user install, set read/write privileges on /tster which is owned by install Not sure what else I need to do to get this working, any suggestions would be appreciated Mark Snyder JMK Computerized TDIS Urbana, IL 61802

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.
