Description rparker@fprep.org 2001-02-28 15:47:36 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)


When attempting to telnet into the Linux system, it requires between 30-60 
seconds for system to respond with "login" prompt. Once connection is 
established, response time is OK.

Reproducible: Always
Steps to Reproduce:
1. Telnet into system from NT/Win98 system.
	

Actual Results:  After 30-60 seconds, system responds with 
expected "login" prompt.

Expected Results:  Login prompt should display in under 10 seconds.

It's trying to do a DNS lookup of where you're connecting from.

Make sure the server machine's DNS is configured correctly, and that the client
machine is resolvable.
Comment 2 rparker@fprep.org 2001-02-28 17:20:08 EST
We don't use DNS for name resolution; we use WINS. Is there any way to bypass 
this feature (whatever it may be), or use WINS for name resolution? Security 
isn't an issue, we're behind a firewall.
