network simulator ns-2

Ns is a discrete event
 simulator targeted at networking research.
Ns provides substantial support for simulation of TCP, routing,
and multicast protocols over wired and wireless (local and satellite) networks.

There are old RPMs for PLD.

Sounds like DNS issues.  i.e. Whatever DNS service your computer using
Outlook uses, it doesn't know anything about mail.csindiasteel.co.in.

Another potential cause is a mixed up internal end external system.
Such as having real public DNS, then trying to use it from with your
LAN, with internal addresses, and the firewall blocking such things.
