Does "qacct -j 2670" tell you more?

This won't forward X Windows - unless you configure it to use "ssh -x".

Which version of SGE are you using?
Which OS are you using?

For SGE versions before 6.2, "qlogin_daemon" should be set to the 
systems telnet daemon, e.g. "/usr/sbin/in.telnetd" on Solaris. You can 
configure it differently, see man page sge_conf(5), "qlogin_daemon" section.

For SGE versions from 6.2 on, it should be "builtin" by default.

The "qlogin_command" settings always must match the "qlogin_daemon" 
settings, i.e. "/usr/bin/telnet" <-> "/usr/sbin/in.telnetd" or "builtin" 
<-> "builtin".

Use "qconf -mconf" to change the global configuration (a local 
configuration is not defined, as the qlogin output tells us).
