Sara,

RH ships telnet off by default, as the other posters have said, you need to set the 
xinet configuration file to switch telnet on.

Other things to watch - probably when you go live rather than during a trial as this 
is how it happened to us...

1.  Xinet limits the concurrent telnet connections to 60 by default.  Add the line 
instances       = UNLIMITED
into the same /etc/xinetd.d/telnet file and run the restart on xinet.  Actually some 
sane number is probably better than unlimited here.

2.  Max open file handles.  cat /proc/sys/fs/file-nr will show the max number of open 
files as the third number.

To increase this add a line like 
fs.file-max = 65536
to /etc/sysctl.conf and run sysctl -p to reload them on the fly - no need for a reboot.

If you are playing about you can just do 
echo 65536 > /proc/sys/fs/file-max but to make it permanent do the above.

Regards,

Adrian
