Automount in Linux ES3.1

[rbri]

New to Linux support....
We just added an ES3.1 Linux server to out NIS domain. It appears that the server mounts all of the users homes that are listed in our auto_home map. My question is how do you configure automount within Linux? These mount points should only happen upon user login.
Thanks

There are 2 files you need to edit.

1: /etc/auto.master which defines the mount directories

2: /etc/auto.misc (or what is defined in auto.master) which defines what exported shares can be mounted.

Linux automount is not like Solaris automount which queries automatically. Linux you have to define everything first.

I wrote a script that uses showmount to add the entries into the auto.misc. If you want I can send it to you or post it.

Hello Clonny2

Thanks for the help I knew about auto.master but, not auto.misc. Please post your script if that's not to much trouble.

Thanks Randy
