A complete tutorial is available on how to get into your HCS account for the first time.
Unix (including Macs): type
into a terminal prompt ("Terminal" on Macs) and enter your FAS password.
Say yes to any questions about authentication.
Windows: download SecureCRT from here and connect to fas.harvard.edu with your FAS username and password.
Then: From the
fas% prompt, type
(note the hcs (that's us!) in place of the fas above)
If you are on the access list for the group, you should get a prompt at your group account (something like
hera:~>), and if you aren't you will be asked for a password, which you won't know (we only provide access through FAS or with SSH keys).
