It is bit hard to describe. I will try list them:


  1. SUSE enterprise 10 sp3
  2. I am using SecureCRT to telnet.
  3. There's two user app and oracle.
  4. I am not in the server room, I can't reboot locally nor remote since I can't get access to root.


  1. I can telnet and login as app or oracle, but if I try root, it just hang after I type root and before it prompt for passwd.

  2. After I login as app(oracle), I can su to oracle(app) successfully. But when I try 'su root', it hang after I type the command and passwd.

So there're two problems in total. Does anyone know anything about it?

Telnet? Really? – Tom O'Connor Dec 18 '11 at 12:38
I don't quite familiar with these remote login thing. I tried ssh on the other server and works fine. but on this server it stop when requesting new channel. So I guess something wrong with the settings and turn to telnet. Telnet works yesterday. Today it just have this root login problem. – GaryX Dec 18 '11 at 14:03

If you have sudo set up, then you could check out what is in root's .bash_profile, .bashrc, and other related startup files. If something is not wonky there, then I would check out your pam stack and see if something is up with that.
