Accessing remote machines

["Giacomo A. Catenazzi" <cate@pixelized.ch>]

Hello.

I want to hack PAM authentification in a remote machine (moving to pam_ldap), 
but I want to be sure to continue to access the machine if something go wrong.

So I ask you: How do you handle special access to remote machines?
For firewall hacking I used 'cron' to disable the firewalls at a specified time, 
 but for PAM it seems some more difficult.

I'm thinking about compiling sshd without PAM support, set some strict rules 
about who/how can connect, and attach it to a 'private' port. Would this works? 
I will act as root without problems, also if my PAM rules are wrong?

ciao
