kickstart: transfer info between %pre and %post
by Florin Andrei 21 Mar '07

21 Mar '07

I collect some info with the %pre script. But I really want to execute some programs, based on that info, during a chrooted %post. The problem is, %pre and chrooted %post do not share any part of the filesystem. In %pre the hard-drives are not yet formatted, while in a chrooted %post the installer's root is not available. How to transfer info between these two stages? One idea would be to upload a file to the kickstart fileserver. That's ugly in many ways. Any other idea? -- Florin Andrei http://florin.myip.org/

Re: [CentOS] CentOS vs. RHEL Advanced Platform
by Jeff 20 Mar '07

20 Mar '07

Thank you Matt, It is the Global File Sharing and clustering that I would like for future implementation. Jeff TheAdvanced Platform adds in things like GFS/Clustering which CentOS hasin the past rebuilt alongside of CentOS 4. I would be surprised to see thatgo away as long as RedHat is still making the SRPMs available as they havein the past. Otherwise, I see no technical differences between RHEL5 and RHEL5 AP - therest are subscription/support differences.Matt-- Matt HyclakDepartment of Mathematics Department of Social WorkOhio University(740) 593-1263_______________________________________________CentOS mailing listCentOS@centos.orghttp://lists.centos.org/mailman/listinfo/centos _______________________________________________ Join Excite! - http://www.excite.com The most personalized portal on the Web!

Need help in securing maildir so that root user should not able to read anyother user's mail
by ankush grover 20 Mar '07

20 Mar '07

Hi friends, 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: a) Postfix or Sendmail as MTA. b) Dovecot or Cyrus Imap with Quota as Pop & Imap server. c) Security of Maildir means even root user should not be able to read any user's mail. d) Global Address Book on Ldap or any other. e) Using samba/ldap for client authentication. Most concerned part here is part c as we don't want any user to be able to read any other user's mail including root. Regards Ankush

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
