Yesterday in class you suggested logging into cslab01 to cslab22 instead of
cslab00. But I tried logging into calsb01.monmouth.edu with telnet but it's not
working. Could you tell me how to login?
Here's the message from Joe Chung:
cslab00 has a SINGLE 1st generation UltraSPARC CPU running at a "blazing"
143 MHz. Imagine how much that single slow CPU has to labor when 10 or more
users are on the system.
If you want compiles to go faster, you should do them on cslab02, 03, 04,
05, 06, 07, 21 and 22 which all have more recent UltraSPARCs running at 400
MHz.
As for your problem, the fully qualified domain name for cslab machines is
cslabxx.cs.monmouth.edu, not cslabxx.monmouth.edu:
$ telnet cslab01.cs.monmouth.edu
Trying 10.1.13.10...

Use the w command to find out how many users are on the system:
