5 Experiments Software Babar From Martin Bly talk Migration of Babar community from RH 7.3 batch service smooth after installation validated by Babar for batch workBatch system using Torque/Maui versions from LCG rebuilt for SL3, with some local patches to config parameters (more jobs, more classes). Stable.

8 One need to install k3b Xmms Multires Xcdroast However:

9 disable the root requirement by editing the files /etc/security/console.apps/xcdroast and /etc/pam.d/xcdroast My files look something like this and it works for me on SL302 /etc/security/console.apps/xcdroast PROGRAM=/usr/sbin/xcdroast /etc/pam.d/xcdroast auth sufficient pam_rootok.so auth required pam_console.so account required pam_permit.so #auth sufficient pam_rootok.so #auth sufficient pam_timestamp.so #auth required pam_stack.so service=system-auth #session optional pam_xauth.so #session optional pam_timestamp.so #account required pam_permit.so #auth required pam_stack.so service=system-auth XCDROAST

10 Kickstart via NFS 1. Make a mount point (not strictly necessary): mkdir /mnt/disk 2. Download the various ISO files for SL. There were four for Make a directory where you'll place the on-line distribution: mkdir /SL mkdir /SL/ Mount each ISO in turn and copy the files from it to the hard drive, as: mount -o loop SL i386.disc1.iso /mnt/disk cd /mnt/disk tar cvf -. | (cd /SL/3.0.3; tar xvfp -) cd umount /mnt/disk mount -o loop SL i386.disc2.iso /mnt/disk etc.

11 5. After the ISO's have been "unpacked" into /SL/3.0.3 (or whatever you choose to call it), export the directory. I.e., add the following line to /etc/exports: /SL/3.0.3 *.ucdavis.edu(ro) where you would replace *.ucdavis.edu by your own domain, then type: exportfs -r 6. At this point you should be able to do NFS installations, assuming, of course, that you have all the NFS "plumbing" already set up. I think that basically amounts to starting the NFS and netfs services. 7. You can initiate the installation in a variety of ways. You may be able to boot from a floppy. See, for instance, /SL/3.0.3/images/bootdisk.img. If you copy that to a floppy via: dd if=bootdisk.img of=/dev/fd0 bs=1440k you should get a bootable floppy, that will ask you for the type of installation (local CD, NFS, etc.). I haven't tried this.

12 PXE We have not done any pxe installation, we hope to hear from RAL experience
