Safe/sane tempfile creation?
by Dr. Ed Morbius 19 Mar '11

19 Mar '11

I'm used to Debian-based distros which have a tempfile(1) utility for safely and sanely creating temporary files. There isn't a comperable utility for RHEL/CentOS systems. I've been exercising Google-fu looking for a good robust tempfile generation idiom, but haven't turned one up yet. Hence this appeal to the lazyweb. -- Dr. Ed Morbius, Chief Scientist / | Robot Wrangler / Staff Psychologist | When you seek unlimited power Krell Power Systems Unlimited | Go to Krell!

Cannot %include in CentOS 5.5 kickstart
by whitivery 19 Mar '11

19 Mar '11

I've previously used includes in CentOS 4.4 and they worked fine. But in CentOS 5.5, trying to specify a driver disk via an include does not work. If I instead specify it directly, it loads fine. When it fails (because it can't see the disk drive - needs the driver disk to see the hard disk), in Console 2 I can see that /tmp/drvdisk exists and has the line I wrote to it. I see nothing that looks wrong in any log or kickstart file/fragment in /tmp. Any ideas? Here's my complete kickstart to show/test this: # Minimal Kickstart test for CentOS 5.5 to show %include problem url --url=http://10.0.4.157/cblr/links/CentOS5.5-i386 text lang en_US.UTF-8 keyboard us timezone --utc America/New_York install bootloader --location=mbr clearpart --all --initlabel network --device eth0 --bootproto dhcp firewall --disabled selinux --disabled rootpw --iscrypted \$1\$x6z.qvwE\$7Zg9g1rCEgvOBoA7Oo/HF1 zerombr authconfig --useshadow --enablemd5 part /boot --fstype ext3 --size 100 --asprimary part / --fstype ext3 --size 1 --grow --asprimary part /var --fstype ext3 --size 10000 part swap --recommended # This does not work %include /tmp/drvdisk # This works #driverdisk --source=nfs:10.0.4.157:/srv/cobbler/RHEL5.5_x86_402_409_410_DD.img %packages @base @core %pre --erroronfail echo "driverdisk --source=nfs:10.0.4.157:/srv/cobbler/RHEL5.5_x86_402_409_410_DD.img" > /tmp/drvdisk # (end of kickstart file)

rpm split
by Janez Kosmrlj 18 Mar '11

18 Mar '11

Hi, I have a custom rpm for our application. The problem is that it grew old and fat. It's about 30 MB. So i would like to split it into two parts. One big part that almost never changes and one smaller part that is changed more frequently. But i don't know how to write the spec file so a simple yum update will install both packages and it won't create any problems. Any suggestions?

Replace NIS by Active Directory
by MOKRANI Rachid 18 Mar '11

18 Mar '11

Hi, I'm looking a wiki or share experience for replace NIS authentication by an existing Active directory Server (W2003). The problem is on the management of id and gid. How to move 1000 actual NIS users to AD ? How to keep the same id and gid for this 1000 users ? What's happen with nfs linux server and acess with gid and/id ? Use the same user/password for linux and Windows clients authentification? We test a solution who work very well. It's Centrify comercial software http://www.centrify.com/directcontrol/overview.asp . But we are looking a freeware solution. (kerberos ? openldap ? pam ? ...) Does someone has already successfully replace NIS by Ad authentification with freeware solution ?

IPV6 - request for info
by Rajagopal Swaminathan 18 Mar '11

18 Mar '11

Greetings, I am trying to wrap my head around on this topic. Was wondering : Just as there is some scope for mapping ipv4 directly into IPV6 space, Is there a MAC ID or some kind of WWID has also been taken into consideration? Regards, Rajagopal

Don't you think there is something slightly farcical about posting messages suggesting people should stop posting messages? > V5.6 will be done when it's done, okay? I don't think the OP did ask when 5.6 would be ready. What he/she said, IIRC, was that Karanbir had suggested that 5.6 would be out last week, and he/she was asking if there had been a problem. This seems a perfectly reasonable question to me. Personally, I am very grateful to Karanbir and his accomplices for what I find an excellent OS, and I don't really care when 5.6 or 6 come out, as the present version works perfectly well for me. However, I don't think people who ask reasonable questions politely should be castigated for doing so. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Hi , all : There is a problem on executing awk command to remote servers; The shell test script is like this : 1. #!/bin/sh 2. 3. _CMD="ssh root@localhost" 4. 5. cpu_num="$($_CMD awk '/processor/{count["proc"]++}; END{print count["proc"]}' /proc/cpuinfo)“ 6. 7. echo $cpu_num My root account can entry the server without the passwd. But I found no result on the screen . Is there some error on that script ? By the way , I googled and found use the following method can run the right result . 1. #!/bin/sh 2. 3. _CMD="ssh root@localhost" 4. 5. cpu_num="$($_CMD << 'HERE' 6. awk '/processor/{count["proc"]++}; END{print count["proc"]}' /proc/cpuinfo 7.
