Hi

I have linux box in my lan, iam doing telnet to linux box from many windows.. it takes time to get the login prompt after giving telnet.. if i put an entry in /etc/hosts it is fast but i hv more than 200 windows pc's in the lan and its not possible to put all 200 entries in /etc/hosts.. is there any way ? i need to get login prompt quickly

at the host you connect to with telnet, look into the /etc/nsswitch.conf, if your hosts first looks into the /etc/hosts file for an Client or if he contacts the DNS. Maybe this will help you.

Putting 200 PCs in /etc/hosts takes only a few seconds. It doesn't care what the entries are so just make a for loop to create the whole address range of your PCs.

The whole operation takes less than a minute.

If you have a firewall you may want to see if hes blocking dns queries. I had the same things with ssh, my firewall was to strict and I have to wait after entering my password.
