ECEN 5033 Lab Instructions and Policies

Please follow all CU and ECE Department Guidelines and Policies in addition to these policies that follow. Special precautions and procedures are required in the ECEE 2B37 Linux lab.

  1. ECE Resources
  2. ECES Student Server Policies
  3. CU Boulder Computing Guidelines.

Please Keep All Source Code on eces.colorado.edu

  1. ssh eces-shell OR ssh eces-shell2
  2. eces.colorado.edu runs Linux 2.6.18 and should be used as your code repository and can be used for code BUILD and TEST that does not require root privilege
  3. ECEE 2B37 Linux Systems should be used to BUILD and TEST ROOT privilege code ONLY and/or code that requires special purpose hardware
  4. All source code should be REMOVED after TEST
  5. NOTE that you are responsible for your sources safe-keeping on eces.colorado.edu and to ensure that other students may not copy your code.

Remotely Logging Into ECEE 2B37 Linux System from ECES Shell

1) Use ssh eces-shell OR ssh eces-shell2 to access eces shell account
2) Use ssh -l root ecertesp1 OR any linux machine from the list of ecertesp1 ... ecertesp15 machines.
2a) Use root password available ONLY on CULEARN to students enrolled in ECEN 5033/4033

Linux SSH Login Example:
   [siewerts@eces-shell ~]$ ssh -l root ecertesp1
   root@10.0.1.112's password: 
   Last login: Sun Jan 20 20:31:02 2008 from 10.0.0.14
   [root@localhost ~]#
3) Check to see if anyone else is already logged in with who
Example where User is Already Logged in:
   [root@localhost ~]# who
   root     pts/0        2008-01-20 20:02 (eces.colorado.edu)
   root     pts/1        2008-01-20 20:52 (eces.colorado.edu)
Here I see 2 logins (one 50 minutes before mine), so I should coordinate use by using wall
3a) Use wall and hit return, then type in message "IS ANYONE USING THIS MACHINE??" and use Control-D to end the message.
3b) If no answer, use machine, otherwise choose another 2B37 Linux host
Example where Nobody is Already Logged in (except me):
   [root@localhost siewerts]# who
   root     pts/1        2008-01-20 20:52 (eces.colorado.edu)
4) Please make a directory under root with your name mkdir username to serve as your workspace for testing code
5) Download code from your eces.colorado.edu account with sftp username@eces.colorado.edu
SFTP to ECES Example:
   [root@localhost siewerts]# sftp siewerts@eces.colorado.edu
   Connecting to eces.colorado.edu...
   siewerts@eces.colorado.edu's password: 
   sftp> cd ecen5033
   sftp> ls
   example-1  example-2  my-driver  my-lab1    
   sftp> cd example-1
   sftp> ls

   sftp> !pwd
   /root/siewerts
   sftp> get perfmon
