ts command not working

[Yogi pn]

Hi,
     When i issue "*ts*" command i'm getting a message command not found. I
tried to see if there is any package by name *ts *in the RHEL CDs, but in
vain. Can you guys help me in getting *ts* to work? What needs to be done
for ts to work. I need this for RHCE exam preparation.

Thanks,
Yogi
