I confused. What is correct and what is not correct?

Hiya, presumably with the comma, "localhost,srv1" is treated by the
resolver as a server name! According to my man hosts, only whitespace can
separate strings. So effectively, srv1 is not present on that 127.0.0.1
line. That's correct: it shouldn't be (IMHO)!
As far as I know, the 127.0.0.1 entry in an /etc/hosts file should just
contain localhost localhost.localdomain, plus nowadays you also see
localhost4 localhost4.localdomain4 . If you install a linux O/S on a
networked machine, that's what you get, in my experience. It should not
contain the external DNS name of the machine.
You could compound the error by adding localhost to /etc/hosts.equiv, or
adding it to submit_hosts in qmgr, and then your qsub would probably work.
But it would still be the wrong thing to do, IMHO!
