Thank you all for your help! I understand ssh is superior to telnet. What I actually intended to know is how to test the "mini" LAN to make sure it works correctly beyond 'ping'. I re-checked the two '/etc/xinetd/telnet' files on both hosts, and 'disable' is set to 'NO'. I reboot the both machine. Telnet is still not working. Neither are ssh, scp, rsh etc. (rsh is the function I really want, I try to install the mpich to test if I can run parallel program and get speedup by using two machines connected by a crossover cable, any suggestions about that is welcomed too). On host1, I type: % /usr/sbin/telneted.d ( I am not sure I spell correctly here) I got some message I remember indicating telnet is already running or something. Then, % /usr/sbin/telneted.d -debug 80 (according to 'man', this is to manually start the server at port 80, seems running) on host 2, I type: % telnet host1 24 again got 'connection refused' How do you know the Telnet server is running? On host 1, I type: % telnet host1 or % ssh host1 It let me login as normal telnet or ssh client, does it mean telnet or ssh server is runing on host1?
