QLOGIN - queue login

The qlogin client command submits an interactive job into Grid Engine that provides the user with a queued login session.

Qlogin uses the same startup mechanism as qrsh:
On the execution host, the shepherd starts a telnetd on a free socket port.
The qlogin client command spawns a telnet to that socket port.

Configuration

Which telnetd and which telnet client command Grid Engine shall use can be configured in the cluster configuration.

The parameter qlogin_daemon parameter defines, which daemon shall be started by the Grid Engine shepherd,
the parameter qlogin_command which telnet client command shall be spawned by qlogin - see also the manpage sge_conf(5).
