Hi
This seems similar like the problem i head with several daemons:
some services (and it seems from what you wrote also telnetd) try to
reverse-lookup the connecting IP address, first in /etc/hosts and then
in DNS with the standard config and so if you do not have the IP of
Box-2 is not in /etc/ho
Can someone explain to me why this happens:
I have a two system LAN connected by a 4 port 10/100 switch. One box is
used exclusively as an Internet gateway. I have a dialup connection and the
connection is managed through this box (call it Box-1). Since this is a
dialup connection, it does N

telnet -4 localhost

If I run telnet localhost 22 then I have to wait 15-30 seconds before it
connects; with telnet 127.0.0.1 22 it connects at once. I have the same
results using other open ports.
Running strace telnet localhost 22 shows that it's trying to resolve the
hostname localhost by querying the nameserver. I

problem, but if they have dynamic IPs then you'd have to work out how to
update the hosts file automatically, which I have never done.
Hope this helps,

My Problem:
telnet and ftp (local network) connections to my server from win clients
(CUTE FTP, MSIE, Putty ...) are very slow:
The Telnet running is not slow when connection is done, so the anoying thing
is just the connection.

Do DNS lookups of uncached hostnames from that box happen slowly too?
Could it have anything to do with it trying to do an ident check on the
person connecting
Hi group - I have seen this asked (and answered) years ago, but am
unable to reproduce the solution.
If I telnet to a new (Debian unstable) box, I get:
Connected to junior.avondel.nl
Escape character is '^]'.
right away, but it takes almost a minute to continue to the login prompt.

time slow even when telnet is the only thing running over the wire?

Hi all,
using http to a remote host works ok, but telneting to the same host
is horrible slow and not quite interactive friendly
Maybe this is an mtu/mru parameter issue?
I did not found anything on telnet rfcs (quick search)
Any addvice will be greatly appreciated...
