How can I disable remote login for a user, only allow "su -" to it?
exactly the same purpose as /etc/user_attr in solaris

You can disable all logins by creating a file /etc/nologin. If the file contains text it will be displayed when a user tries to log in. Root can still login and so can FTP users.

but how about I only want to disable one user e.g. user "abc" instead of all of them? I can't lock the password because people still need to su to "abc", I just don't want ppl to use "abc" to login.
pls help, thx.

How are the remote users logging in? If it is via SSH then you can disable user/host logins via the ssh config file.
