[opensuse-autoinstall] Deriving hostname for .xml file from PXE client & setting values in /etc/sysctl.conf
Dear all, Question 1: I am trying to construct a generic autoinst.xml file for several clients. The template I am using is the one generated from one server, an HP Blade, found in /root/autoinst.xml. I intend to use this from within a file called this, (the MAC address is made up) # cat /tftpboot/pxelinux.cfg/00-00-00-00-00-00-01 default SLES11 # install SLES11 - Dummy entry for generic profile label SLES11 kernel vmlinuz append initrd=initrd ramdisk_size=65536 install=nfs://10.205.8.145/export/sles11-dvd1-i586 hostip=10.205.8.123/24 autoyast=nfs://10.205.8.145/export/generica-sles11_i586-autoinst.xml netdevice=eth0 textmode=1 insmod=bnx2 The autogenerated file contains host specific entries like, <host> <hosts config:type="list"> <hosts_entry> <host_address>10.254.66.90</host_address> <names config:type="list"> <name>newHPserver newHPserver</name> </names> </hosts_entry> <hosts_entry> <host_address>127.0.0.1</host_address> <names config:type="list"> <name>localhost</name> </names> </hosts_entry> <hosts_entry> <host_address>127.0.0.2</host_address> <names config:type="list"> <name>newHPserver.it.lan newHPserver</name> </names> I would like to have this xml inherit the hostname, IP address from the client that called it. Question 2: In most cases these servers will run Oracle. Therefore I would like to some how add values for shmmni shmmax and so on for Oracle. I expect to have a separate .xml file somewhere that would set these values. What is the way to so this? I thought that I could use some xml like this but I don;'t know if this is the preferred way in the SUSE world? <script>echo "kernel.shmall = 2097152" >>/etc/sysctl.conf</script> How would I instruct autoyast to call this file?

You can basically re-write the entire profile in the pre-install scripts if you want, and could do what you're looking to do (and a lot more) there. Just output a /tmp/profile/modified.xml file and it'll be re-read after the pre-install scripts are run. I do several things using comment tags that are replaced by a pre-install script that replaces them based on common names.. e.g. compute_single.xml: <comment>SWAP_DEFAULTS</comment> scripts.xml: <comment>NET_DEFAULTS</comment> scripts.xml: <comment>NIS_DEFAULTS</comment> scripts.xml: <comment>NTP_DEFAULTS</comment> scripts.xml: <comment>CLK_DEFAULT</comment> scripts.xml: <comment>ADDON_DEFAULTS</comment> scripts.xml: <comment>ROOTWORD_DEFAULT</comment> scripts.xml: <comment>TZ_DEFAULT</comment> The script looks for any VALUE_DEFAULTS then in a case statement runs the right subroutine to replace the comment tags with xml for the profile.. the above do things like dynamically set the swap space (different admins in our offices wanted to be able to set different amounts of swap), outputs the entire <networking> section (which is what you're mostly looking for), NIS info (mostly deprecated), etc. These were originally put in place to allow a shared set of identical files with one configuration file per site read in to put in site specific values without super complicated rules.xml setups, which have their own short-comings.

You can also do this type of thing in either the chroot or post-install scripts. The ways to do pre/chroot/post scripts are pretty well documented in the autoyast docs. -- Mike Marion-Unix SysAdmin/Staff IT Engineer-http://www.qualcomm.com "Only wimps use tape backup: _real_ men just upload their important stuff on ftp, and let the rest of the world mirror it ;)" (Linus Torvalds, about his failing hard drive on linux.cs.helsinki.fi) -- To unsubscribe, e-mail: opensuse-autoinstall+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-autoinstall+help@opensuse.org
Dear all, I set-up the server, and it passes out the DHCP lease as shown below. However, when the client tries to contact the TFTP server it attempts to do so on 0.0.0.0 instead of t2nl-app205.versatel.com. Below are the files and part of a tcpdump from the session detailing some of the TFTP communication. Somethin I have missed but what it is I do not know. Does anyone else know?
