[newbie] Unable to telnet into Mandrake box

[Jason L Bowne/BOWNJL/LMITCO/INEEL/US]

Hello,
     I just installed Mandrake 6.1 on HP NetServer LH Pro, and love it so
far..
I am in the process of decommisioning an HP9000 UNIX server that is serving
our web page and just can't see how paying the $3000/year maintenance fee
on HP-UX is a benefit, when a better, faster, stable OS is free!
     Anyway after installing, everything seems to work but a few little
quirks,
I can't telnet into the linux box.?? I have been researching and
researching and
I must not be researching in the right place.  I looked in the inetd.conf
file and there
is a section for the ftpd and the telnetd, but if I do a ps -ef |grep
telnetd it isn't running.
I can ftp into it just fine??  Any help appreciated.
     Also if i 'ping hostname' it won't ping, if i 'ping hosname.xxx.com'
it works.
Where is the DNS stuff at that I need to change for that to work..
