The file ~/.ssh/jjacobs-s1t.config

This is an instance of a user-specific file to create the linkage from server-1p to server-1t. It currently hops to usno-serv-1 then to gygax and finally to server-1p. The ssh command is run by root so it can modify the files on server-1p but it needs to use admin to log into usno-serv-1, then the appropriate NRAO user to get into gygax and finally as admin on server-1t.

There will need to be one of these files per NRAO administrator since each will use their NRAO account to get onto gygax.

# Configuration file used to get patches from server-1t via rync.                                 
#                                                                                                 
# As configured it hops from server-1p to usno-serv-1 to gygax to server-1t.                      
# First it will ask for the user's NRAO password to get access to gygax                           
# and then it will ask for the admin password to get into server-1t.                              
#                                                                                                 
# When server-1p gets its own VPN connection back to NRAO then this can                           
# be simplified.

# It can also be used to ssh or scp to s1t by simply doing                                        
#
