-No.
+Outgoing email only.
 ===== How do I change my password? =====
-Use the ''passwd username'' command on ''balboa.ucsd.edu''. After a brief delay, the password change should propagate to all of the servers. If it's been a month since your password expired and you have not changed it you will no longer be able to logon and need to reset the password in person - please contact keck-help.
+If you are logged into one of the Keck workstations execute command ''passwd'' to change your password.

-===== How can I setup an SSH tunnel to the KeckII workstations from outside of UCSD? =====
-If you need to directly log in to one of the Keck II workstations from outside of UCSD - for example if you need to run an X-window application or copy files directly you can set up an SSH tunnel for this purpose.
-On you linux or Mac machine execute the following:
-<code>
-ssh -f -N -L 2042:w05.keck2.ucsd.edu:22 YOUR_USERNAME@balboa.ucsd.edu
-ssh -p 2042 -X YOUR_USERNAME@localhost
-</code>
-The last command will log you in to ''w05.keck2.ucsd.edu'' where you can start your X-window application and it should display on your local machine.
-An alternative and much simpler command to use is:
-<code>
-ssh -o 'ProxyCommand ssh user@balboa.ucsd.edu -W %h:%p' user@w01.keck2.ucsd.edu
-</code>
-However, this only works with OpenSSH version 5.3 and newer.
-===== How can I ssh/scp from the KeckII workstations to outside of UCSD =====
-All KeckII workstations are on publicly non-routable vlan so you have to use the gateway ''balboa.ucsd.edu'' to go outside of UCSD:
-<code>
-ssh -o 'ProxyCommand ssh balboa.ucsd.edu -W %h:%p' tg80XXXX@stampede.tacc.utexas.edu
-</code>
-and to use scp to transfer files to outside of UCSD:
-<code>
-scp -o 'ProxyCommand ssh balboa.ucsd.edu -W %h:%p' your_file tg80XXXX@stampede.tacc.utexas.edu:
-</code>
-If you use these commands often you might want to put the ''ProxyCommand'' option to your ''.ssh/config'' file:
-<code>
-# set up proxy to access stampede (outside UCSD)
-Host stampede
- Hostname stampede.tacc.utexas.edu
- User tg80XXXX
- ProxyCommand ssh -W %h:%p balboa.ucsd.edu
- Ciphers arcfour
- ClearAllForwardings yes
