Linux Provisioning Systems - Posted by jpr to provisioning sysadmin linux on Thu Jan 11 2007 [@lab Bookmarks]

[phpwiki]
Came across an article today in [NetworkComputing| http://www.networkcomputing.com/channels/storageandservers/showArticle.jhtml?articleID=194300555&pgno=11] (of all places. nothing quite like boardom induced browsing) that caught my interest. I've been scratching my head for a while on how to manage the desktops, servers, and hpc systems in a reasonable way. The best way to do it is some ROCKSish like way, essentially having some configuration management tool. ROCKS and OsCaR are nice but a little too geared to the HPC cluster environment and don't seem adaptable to general purpose system administration with out a lot of cross platform (non-redhat) headache. I've toyed with the idea of roll my own via the grid but don't like the isolation of it.

Secure and Informative User Authentication Using UAB's ldap Server

About this document

Original author: Jason Nance <jbnance>
Research by: John-Paul Robinson <jpr>

This doc is an overview of the configuration of pam_ldap for user authentication using UAB's ldap server for password validation and your own ldap server for account enumeration.

NOTE :: This doc does NOT detail the setup of your ldap server, but does assume you have a working configuration and a knowledge of how to add/modify entries.

rocks and oscar

|

seems oscar and rocks follow similar logic. oscar seems a little rougher
but also includes some stuff from major compute centers like oakridge and
ncsa. both are based on redhat-ish distros. they do use similar
approaches to build images, though oscar seems to do more custom building.
seems it takes system rpms and installs them at a different base for the
nodes. both install systems on the nodes and don't share a common central
system. this is fine but does have an install overhead. this is kinda
expensive (i think) for a desktop machine since their likely to have a lot

an unexpected 15 minutes

had xmms on pause overnight, clicked play/pause, then immediataly
skip-to-next-song, this caused the entire desktop to freeze. even warm
reboot didn't work. had to pull power. afterward booting took a long
time at grub stage 2. assume it was a currupted log/journal. after a
complete boot, the boot times returned to normal. had feared a bad disk.

desktop publishing

read over a [linux journal article on desktop publishing|http://www.linuxjournal.com//article.php?sid=7495] with openoffice. it's a simple primer on
a complex topic but gives enough of an intro to know the terms and some of
the basics acts of a powerful technology.

suse9 on dell650 still loosing network connectivity it seems

suse9 box still seems to lose the network interface, only record of this is the link status msg when dhcpd does its resolv.conf writing. need to see about turning on debug for this driver to see if any operational stats can be recorded.

The ssh connection was again dropped this morning do to a connection reset. Don't know if this is due to network connection loss or an ssh timeout config.

I'm not seeing the nfs timout errors previously seen with this error but that could just be do to lack of nfs activitiy.
