If you can't login, please read the rest of this document first, and if things still aren't working, send mail to your instructor (agn@cs.cmu.edu).
If you are having trouble logging in, please send mail to your instructor.
If you're not on the list, please request an account from
Andreas Nowatzyk (agn@cs.cmu.edu).
Q: What do I need to do before logging in for the very
first time?
A: From your Andrew home directory on one of the Andrew
Unix cluster machines (linux.andrew.cmu.edu or
unix.andrew.cmu.edu),
run the following one-time checkin script:
unix> /afs/cs/academic/class/15213-f04/bin/checkin
Important: Before you run this script, make sure you do not
have any subdirectories in your Andrew home directory called
15-213 or 213hw. If you do, rename them
before running the checkin script.
Q: What does the checkin script do?
A: It creates two subdirectories in your Andrew home
directory: 15-213 and 213hw.
The 15-213 directory contains the .klogin
and .login files that will allow you to login from the fish
machines. DO NOT DELETE ANYTHING IN THIS SUBDIRECTORY.
The 213hw directory contains secure subdirectories for each of
the labs, with the permissions set so that only you can read
the contents.
Remember, you only need to run the checkin script once, before your very first login to the fish machines.
Q: How do I log into one of these machines once I have run the
checkin script?
A: From your home directory on an Andrew Linux or Unix machine
(e.g., linux.andrew or unix.andrew),
if your Andrew login is bovik and you want to login
to the fish machine called chum.cmcl.cs.cmu.edu,
then login as follows:
unix> ssh -1 -l bovik@ANDREW.CMU.EDU chum.cmcl.cs.cmu.edu
[type your Andrew password to the prompt]
Notice that the uppercase 'ANDREW.CMU.EDU' is significant.
That's -1 (dash one) followed by a -l (dash
el). For some SSH clients you must explicitly specify -1
to request the SSH version 1 protocol. With some clients, you may
be able to login without the -1:
unix> ssh -l bovik@ANDREW.CMU.EDU chum.cmcl.cs.cmu.edu
[then type your Andrew password to the prompt]
Q: I did everything you said but I still can't login. Now what?
A: Here are the most common reasons students can't login:
unix> cd
unix> fs sa -dir ~ -acl system:anyuser l
unix> fs sa -dir ~/15-213 -acl system:anyuser rl
Intel engineers traditionally use the names of North American rivers as internal names for their processor projects. So it seems fitting that we, as denizens of the Intel cluster, name the machines after freshwater fish of North America.
