Creating ssh keys and logging on

the security we use requires ssh keys

Apple MAC people

open a terminal and enter the command

"ssh-keygen". Accept all default filenames. 

Choose a passphrase when asked for one. Then email the sys admins the file

.ssh/id_rsa.pub

Directories starting with a . are normally not visible, so it might be easiest to first copy that file into your home directory:

cp ~/.ssh/id_rsa.pub
