Sorry to ask questions:
a) How did you login in, putty ssh, etc?
b) Did the commands work?
c) Try echo "fun fun", do simple commands work ok.
d) df ?? Disk space ok ?
e) ps -ef, what does that show ?
2 cents, JB

Well, the one time I have been in this situation, it turned out that the
VPN link through which I was accessing the server was fragmenting
packets and the assembly at the other end was not happening correctly (I
think the VPN peer device had a bug).

You might want to involve your network administrators in troubleshooting
this further. If I read it right, commands with small amount of output
work fine, while commands with large amount of output would hang the
session.

Fix your terminal with command

stty intr ^c

(two letters ^ and c)

And now you should be able to interrupt with

Ctrl-C

(hold Ctrl key and hit c key)

Trace the system calls for "ps -ef" with

truss ps -ef

the last stat() command should be the one that is hanging.

Probably it requires a name server (e.g. NIS server) that
is not responding.
