telnet is too slow in Scientific Linux

[Edison, Arul (GE Healthcare)]

Hi All,
        In my system, I want to provide telnet feature and hence I installed 
the telnet rpms . however I found that , when connected from another system 
with telnet command, it takes 30 mins to show the telnet login prompt.
        Is there any configuration needed to be performed to make the telnet 
fast?
Many Thanks,
Arul
