Everything you need to log in, move data, and reach pages that are only reachable from campus.
All commands below assume the default SSH port. If your account was set up on a
non-default port, add -p <port> to any command here — check with
uhpc@unam.na if you're not sure.
Use the SSH key pair you received when your account was approved.
ssh -i ~/.ssh/unam_hpc_key <username>@uhpc.unam.na
Never share your private key. Report a lost or compromised key to uhpc@unam.na immediately.
Send files to the cluster with scp. Large datasets belong in your
~/data directory on the shared storage rack, not your home directory.
scp -i ~/.ssh/unam_hpc_key myfile.dat \ <username>@uhpc.unam.na:~/data/
Some pages — the H.E.S.S. Paris Analysis documentation and the Namibian WebSummary among them — are only reachable from the UNAM campus network. You don't need a full VPN to get to them: the head node can forward a SOCKS proxy over your existing SSH connection.
This connection does nothing but forward traffic — leave it running in the background while you browse.
ssh -D 1111 -f -C -q -N <username>@uhpc.unam.na
In your browser or system network settings, configure a manual SOCKS proxy:
| Setting | Value |
|---|---|
| SOCKS host | localhost |
| Port | 1111 |
With the proxy active, campus-only pages load normally. Switch the proxy off (or close the SSH connection) when you're done.
See Paris Analysis & H.E.S.S. access for the
specific campus-only pages this unlocks, including the H.E.S.S. WebSummary
(base.hess-experiment.eu, port 8005) and the ParisAnalysis documentation.
For anything beyond loading a web page — running a GUI application, for example — use Remote Desktop (VNC) instead of the SOCKS proxy above.
