Maintaining a Debian/Ubuntu repository on Redhat (or other linuxes)

At work we have a repo server that runs Redhat.  I couldn't find a good way to maintain a Debian/Ubuntu repository on it, so I built a solution.

Basically I built a chroot environment that when run takes packages from the incoming folder and turns them into a repository that you can put on your webserver.

I'm sure there are more elegant solutions (though I couldn't find them), but this serves my purpose at least.

This script will create the chroot environment for you.  Run the script on a debian box, copy the tar ball to another server, untar it, put files in the incoming directory and run the included script.

Fixing broken trust relationships in windows server

I was looking around for a reference to send to a colleague who had a server lose it's domain relationship and found this one which seems to work really well.

Basically, log in to the affected server and run:
netdom.exe resetpwd /s:<DC hostname> /ud:<domain\user> /pd:*

Over riding puppet modules

I've discovered that you can overload parts of puppet modules.  This means I can still use the module but just overload what I need.

Of course, modifying the module may be tidier but modifying a module used by lots of production servers is not a trivial undertaking.

Here's how it works:

class systems::section::authssh inherits auth::ssh {
   File['/etc/pam.d/sshd']{

      content=>"blah"

  }

}

This means I get all the good stuff from auth::ssh but I can override the sshd pam configuration for this server/group of servers.

The case I was dealing with was a bit more complicated (though same concept), in modules I have auth::thistype which includes auth::pam

I would normally include auth::thistype and just to complicate things the setting I want to change is in auth::pam.  Unfortunately (in this case) puppet won't let you modify an argument in a class that isn't the one setting it (or a sub class thereof) so I can't set it in the class as above, I need to set it in the correct class, like this:

class systems::section::auththistype inherits auth::thistype {

  include systems::section::authpam

}

class systems::section::authpam inherits auth::pam {
   File['/etc/pam.d/sshd']{

      content=>"blah"

  }

}
