Linux resource discovery...

 PMP uses TELNET as the remote connection mode to discover the Linux/Unix type of devices.

We have hundreds of Linux workstations and servers, but not ONE of them is running a telnet server or allowing access on port 23.   I can't imagine that any security conscious sysadmin anywhere *would* allow telnet access to servers.

so how exactly is this discovery supposed to work?   Unless I'm missing something, it seems like this "discovery" feature is entirely unusable in any normal environment.
