[Pkg-monitoring-maintainers] Bug#932370: mon: remote.monitor gives Perl errors if remote server requires password

Package: mon
Version: 1.3.3-4.1
Severity: normal

Below is what happens when trying to monitor a remote server that requires
authentication (or a server that disconnects abruptly, a server not running the
mon protocol, or many other potential protocol issues).

Firstly support for username/password authentication is a wishlist item.

Secondly having the program always display user-focused error messages rather
than Perl diagnostics is expected.

$ /usr/lib/mon/mon.d/remote.monitor server
Odd number of elements in hash assignment at /usr/lib/mon/mon.d/remote.monitor line 162, <GEN0> line 2.
Use of uninitialized value in list assignment at /usr/lib/mon/mon.d/remote.monitor line 162, <GEN0> line 2.
Exiting subroutine via next at /usr/lib/mon/mon.d/remote.monitor line 187, <GEN0> line 2.
Exiting eval via next at /usr/lib/mon/mon.d/remote.monitor line 187, <GEN0> line 2.

Details for server failure :
list_opstatus failed:520 command could not be executed, unknown command
