Documentation and howto
by Andrea Carpani 20 Mar '07

20 Mar '07

Hi all. I'm really intrested on how the CentOS team rebuilds all of the packages from the src rmps: build environment, setup, tips and tricks. Is there documentation about this somewhere? Thanks. -- Andrea Carpani <andrea.carpani(a)criticalpath.net> Critical Path

automated install over network
by Dave 20 Mar '07

20 Mar '07

Hello, I've got a machine i'd like to put CentOS 4.4 on. Unfortunately this machine doesn't have a rom in it, just a floppy and a network card. I was wondering if i could boot it, then have it pick up what it needs to start the install off the network and do an unattended install vi nfs? Or, if that's not possible would it be possible to boot and load CentOS completely from the network bypassing the hard disk altogether? I don't need x on this box, in fact it doesn't have a monitor, most of the work it will do will be via ssh, or unattended stuff. Thanks. Dave.

Centos 5 [Beta] on 3ware 9650se controller
by Jason Harper 20 Mar '07

20 Mar '07

Unfortunately, it doesn't appear that CentOS 5 Beta (or likely final) supports the 3ware 9650se card. Since 3ware hasn't released a driver disk yet, I put one together. It supports CentOS 5 Beta, and may/should support Final. If anyone is interested, I've posted it here: http://www.truedesign.org/3ware-centos5/ Jason

phpMyAdmin high Memory usage
by Matthew Martz 20 Mar '07

20 Mar '07

I installed phpMyAdmin on CentOS 4.4. When accessing phpMyAdmin the memory usage jumps. Memory usage for http jumps to 700MB spawning 4-5 httpd processes (about 3GB of ram). Mysql also jumps to using close to 600MB in some cases This is a Daul Dual core Xeon 3GHz machine with 4 GB of 667Mhz ram. Should I be seeing this spike in Memory usage? The spikes only last about 5 seconds but my manager doesn't want to see those jumps. The databases appear to be about 450MB-600MB. On a side note I had a requirement from the dev group here to set php to a maximum memory usage of 1GB due to the large files that are being parsed via a web page. Any help would be appreciated. Thanks! -- Matthew Martz CentOS Mirror Admin mdmartz(a)gflug.net

selinux ntp samba error message
by Brett Serkez 20 Mar '07

20 Mar '07

Just prior to the time change, I made sure that ntpd and my timezone files were properly setup. Since this time, I've noticed the following errors: audit(1173310084.404:5): avc: denied { read } for pid=8634 comm="ntpd" name="unexpected.tdb" dev=md1 ino=147662 scontext=root:system_r:ntpd_t tcontext=root:object_r:samba_var_t tclass=file I've not successfully (so far) been able to find the selinux setting that is denying this access. I am running a reasonably standard (i.e. minimally customized) CentOS V4.4 system and have to believe there is a general change that should be made. Has anyone else seen these errors? Has anyone else resolved this issue and can describe how to resolve? Brett

GNU Telephony Centos repository
by Robert Moskowitz 20 Mar '07

20 Mar '07

The Gnu Telephony site: http://wiki.gnutelephony.org Has a Centos repo: http://dist.gnutelephony.org/RPMS/ But I caught some text stating that this is for Centos 4.2. Is it really? Is there a difference; i.e. would it be safe to install these on Centos 4.4? Really I am after Twinkle, and it seems there is a lot you need to actually get Twinkle installed...

HP DL585 G2 -- no nics
by David Mackintosh 20 Mar '07

20 Mar '07

Hi folks, I've just spent about six hours messing around with an HP DL585 G2 server trying to get CentOS to go. This box is a dual-CPU with dual cores and 10GB of RAM total. According to the datasheet, the POST screens, and the BIOS, it has the Broadcom embedded NICs in it. The problem boils down to the installed OS (4.4 x86_64) not seeing the NICs. If you do an lspci on the system after installing from local media the only unknown device is one of the built-in hardware health monitors. And since the NICs don't show up in the pci table, there's nothing for the drivers I downloaded from the HP website to hook to. What's interesting is that in the process of trying to get this thing going I've installed two old (2002 vintage) 3Com 905cxl PCI cards in the system -- again, the BIOS (or whatever the built in hardware diagnostics program is called) sees them, but the running OS does not. This implies I've done or missed something trivially stupid, and after banging my head against this box and the monumentally unhelpful HP "documentation" I was wondering if someone had been down this road before. Any insights would be appreciated. Thanks! -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com

RE: Need help in securing maildir so that root user
by Jun Salen 20 Mar '07

How much cost do you currently spending in your Exchange setup, can you give me an idea so that I know how much I am saved using my current setup. Postfix, Courier, ClamAV, SpamAssasin, Roundcube and MailScanner. All this under the roof of CentOS. Thanks. ---------------------------- My company is currently using Exchange Servers for Mail Server solutions but now they want to move to Linux Servers due to heavy cost involved with the Exchange Users.We will be using the latest version of Centos. So the kind of solution we are looking is below: junji linux registered user #253162 Send instant messages to your online friends http://uk.messenger.yahoo.com
