Pool and hosts with different users

[Sergey Yelin]

Hi list,

playing with erlang poll a have found interesting feature. Access to remote
hosts implicitly requires existing user with the same name in all hosts
listed in .hosts.erlang file (because underlying transport, e.g. rsh/ssh
requires it).  In my case I have a few hosts with different user names, so I
need explicitly specify user name for every hosts. According ssh rules I try
to specify it in .hosts.erlang as "'user@REDACTED'." , it works in one direction
only: master can login to slave host but can't start slave node because of
wrong name format "queue@REDACTED@host".

So, is there any other ways to specify user for slave nodes?

File .hosts.erlang on master host (robby):
'slave@REDACTED'.


Error on slave node (found in ssh debug log):
