Linux authentication and authorization: sudo with LDAP support


While searching the sudo manual for samples and explanations, I discovered that my Oracle Enterprise Linux 4 update 5 uses sudo version 1.6.7p5. The official version is up to version 1.6.9p9. Interesting is, however, that the new version has means to integrate with LDAP!
That means, that instead of maintaining a central /etc/sudoers file, you can build your authorization tree in LDAP, where you can also handle your authentication! Cool! Of course, by LDAP I mean OpenLDAP, Novell NDS, Oracle OID or even Microsoft AD...

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Dell Linux - OMSA Hardware Monitoring

Just getting started using Dell's OpenManage Server Administrator (OMSA) on our Oracle Linux platform. There are some confusing instructions going around so it's not immediately clear what to do, hence my blogging here. :) There is a site on Dell - Hardware Monitoring , as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date. [update]My first update for their instructions: be sure your server has Internet access, as most servers will use a proxy or so. use export http_proxy=http://yourproxy.example.com:port to configure it just for the session, and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date .
