Students typically use VNC to connect to Math & CS servers such as sand from other on-campus computers. Unfortunately, the incoming VNC ports are blocked at Truman's firewall, so VNC cannot be used directly to connect to on-campus resources from off-campus locations.
If your off-campus computer is a GNU/Linux system, a Mac OS/X
system, or some other Unix-based system such as Solaris, you don't
need VNC at all. Just open a command window and give the
command:
ssh -X username@sand.truman.edu
and you're connected.
If you are unfortunate enough to have to use a Windows-based computer for an off-campus connection, ITS recommends that you set up a VPN connection for connecting to on-campus resources such as VNC and network drives. See ITS's instructions for details.
Direct off-campus connections to network drives are blocked at the firewall. However, ITS provides VPN connectivity for network drives. See ITS's instructions for details. Alternatively, once you have a connection established to sand, you can mount your network drives on either of them and thus access your network drives from off campus. To mount a network drive:
One time only, make a directory to serve as a mount
point:
mkdir ydrive
Give the smbmount command:
smbmount //hydrogen.truman.edu/ID ydrive -o
username=ID,workgroup=truman
where ID stands for your network username. You will be
prompted for your network password; after supplying it, your Y:
drive contents will be available in the ydrive directory. When
you are finished, unmount the drive with:
smbumount ydrive
Note that using the smbmount and smbumount commands in this way
requires them to be installed setuid on the system. Currently, this
is not the default on Ubuntu systems. To make these
programs setuid if they are not, on a standard Ubuntu system, one
time only give the command:
$ sudo chmod u+s /sbin/mount.cifs /sbin/umount.cifs
The other network drives are similar. Make a directory for each, and vary only the network name. Currently, the names are:
S: drive: //ss1.truman.edu/win_apps
T: drive: //www2.truman.edu/ID
U: drive: //hydrogen.truman.edu/Student_files
Good luck!
