Pam Update, security pam_limits and 64 bit libs

ok, so, you have an x64 server and you updated pam, and you want to use pam_limits - cool story. until you try to login...and you're like, why isn't it working? because you added the line:

session required /lib/security/pam_limits.so

to /etc/pam.d/login

but you CAN login remotely and you check your log files and see 'Module unknown' when someone tries to login locally. This is because you're a 64bit server using a 32bit library...from /lib...so change that line to

session required /lib64/security/pam_limits.so

Then local logins work. =)

Updated on SSH Key authentication.

Public key authentication is great, as most of us have known for years, but I'm still in the middle of converting everyone to it who use the systems where I work.  Its actually a pretty big task since so many people do have to connect into our servers in order to get information...and if those accounts cannot connect then...well, stuff starts breaking.

We've done really well and our systems are really stable, of course they're still running HP Unix, but the new systems that are on their way into production are RedHat Linux (RHEL 5), so we have our work cut out for us. No problem -- They seem to be quite resilient and stable.  I wish we could get some Oracle on BSD. Grr.

Anyway, a lot of interesting changes going on in the workplace right now, so, I'll leave those for another time. Just wanted to give a quick update to all the readers out there... I'm still alive. Thanks for your emails.
