Hi everyone

I installed Redhat Linux 6.2 and i enable telnet also
when i try to telnet to this server from my windows client (95 and 98)
it takes long time (almost 55 second) to show the login prompt. all PcS

ARE ON LOCAL NETWORK.

I want to reduce the Login-prompt time. How can this be achived. All

users who are using Linux server are Trusted user.

Thanks in advance

dns. Either configure a dns for your local network, or put
the ip addresses/names in /etc/hosts file.

Seems to be a typical DNS problem. Check the following:

When logged in the linux box, check your source IP by
questioning 'w' command. If you get a numerical IP address
that's the problem...
Linux tries to resolve your numerical source IP and does
not succeed - therefore you get the 1 minute timeout (about).

Solution:
- Configure reverse DNS for the source IP address by
setting it up in your /var/named configuration or simply
adding this ip to your /etc/hosts file.

TCP Wrappers tries various methods to make sure that your machine actually
is who it says it is before allowing a connection:

1) ip to name resolution - tcpd looks for a PTR record from it's DNS
servers.

2)name to ip resolution - tcpd then looks for the A record for that name,
looking for a match with the results of 1)

3) If tcpd was compiled to do so, it will use an AUTH inquiry to attempt to
identify the user.

See Vilmos and Stefan's recommendations to fix 1 and 2. If you are doing
AUTH lookups, you will have a delay while the AUTH lookup times out for a
Win client, and Win doesn't support inetd.

Disable the Reverse Name resolution would be a better choice.
You may telnet from different locations.
But if you just telnet from one place, just put the follow that instruction.
