Hi Eric

When taking a look at

it seems like the login nodes are called 'loginXX' (with X being digits), and from there you ssh into 'mesabi', but end up on nodes with hostnames 'lnXXXX' (with X digits again). This suggests a common file system, in which case you should be able to use a regular expression like ^ln[0-9]{4}$ in 'aliaspattern' (depending on what 'hostname' actually returns on those head nodes; you might have to extend for the fully qualified name).

(Or even more restrictive ^ln000[1-6]$ if you like.)
