Re: System Hardware Tracking
Chris, I've dreamed of a uniform system for managing and tracking system configurations. Agreed that configuration management is no problem with a few systems, but grow the list to 100+, and there's many a potential management problem brewing. I currently use some batching scripts to distribute updated code, but its far from a complete or ideal solution. The lack of free time has stopped me from building or implementing anything more complicated, but you may be interested in the following: The Arusha project: http://ark.sourceforge.net/ Configuration management tools: http://linas.org/linux/cmvc.html other... http://cbbrowne.com/info/linuxsysconfig.html I'd be interested in hearing of any other OSS solutions that have client machines updating to/from a central database with their current hardware and software configuration.

Re: System Hardware Tracking
If you want something to build on, then maybe IRM might do it. php/mysql. We've hacked it too met our needs - it seems ok. It's a debian package too. jamie On Wed, 2003-12-03 at 06:35, Chris G. wrote: Well it's finally hit the point where we have a few machines where we have no idea what's in them.

Re: bind9 vs tinydns vs others
thanks for reply! i only guess, as well as your dns depends on some database (RDBMS or LDAP or something else), it increases the danger of attacks, especially DoS (db is down - dns respectively). flat files can't be down. wouldn't be better to generate flat files from the backend db to avoid such risks? have you ever had such problems?

Works like a charm. Only drawback is it's only available in testing and unstable (but most of our servers un testing and are rock stable) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Tool for changing ips in all needed config files...
Hi, is there a tool to change all occurences of a servers ip-address? I am trying to sync some servers and want to use ONE basic configuration for all. Only difference now is the ip in some files in /etc, that somehow complicates the simple concept of rsyncing all servers from a master server. I am sure that someone had this problem before. Could you point me to some interesting solutions? Thank you very much for your attention! Peter -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: Tool for changing ips in all needed config files...
cfengine is a tool built for this sort of thing. It allows you to apply and configure systems while still maintaining their identities. It's a very complicated tool though FYI. --On Wednesday, December 03, 2003 21:24 +0100 [EMAIL PROTECTED] wrote: Hi, is there a tool to change all occurences of a servers ip-address?

I would agree with you, others may not. It's trivial to generate appropriate zone files from a database so (assuming you want your zones in a database) I'd still go with generating the files periodically rather than having DNS constantly polling the db.

RE: /etc/lilo.conf and system.map mismatches
Try putting the map=... Line in the specific to kernel section. map=/boot/map Is this the way it looks in your lilo.conf file? Hope this does the trick. Eddy Petrisor
