I have just installed redhat 6.2 on 5 new computers networked with a 5
port ethernet hub.
After installing all of the software and setting up the IP addresses,
etc., all seems fine except that when I attempt to ftp to any machine,
there is a very long delay before I get to the username prompt. I see
the "connected to" message, but then I have to wait for what seems to be
a full 2 minutes or so before I can log in.
Telnet connects without a delay, and pinging does not indicate any
traffic problems. Once I (eventually) get connected to the remote ftp
server, transfers also work at nominal rates.
I am not a networking guru, so I am somewhat puzzled about what might be
going on. Any advice on what I should do to diagnose this problem?
