Dear all,

I am using RH6.2. I set up Samba and Netatalk successfully.

However, when I finished the set up process and tried to connect to the
server by telnet or ftp, it would take a long time to setup the connection
(>1 min in a 100Base LAN)

What's wrong with that?

Thx for your help.

Yours,
Bill

You might like to check to make sure that the hosts are able to work out the
hostname for the incoming connection. This means either check your DNS
settings in your /etc/resolv.conf file or add the IP addresses into your
/etc/hosts file. I suspect the time that you spend waiting for your
connection is the machine trying to find out the hostname of the IP address
connecting into it.

Normally this can be seen when you do a "finger" on the local machine and you
see yourself connected from a IP number rather than a canonical name.

See ya

I'm having a similar problem. I'm running RH6.0, but recently upgraded
the kernel to 2.4.1 in order to compile in support for my Compaq Smart
Array controller. Everything seems to be working fine (eventually) but
for some reason networking services seem to be very slow to react.

At first I blamed the NIC and/or driver, but the same thing happens
when you use the local loopback. For example: telnet 127.0.0.1, or ftp
127.0.0.1 (wu-ftpd v. 2.4.2). I'm using IP addresses so I figure no
need to worry about any possible DNS issues. The odd thing is that it
appears to connect immediately because I get a message saying
"Connected to 127.0.0.1", but then it takes up to several minutes to
get the logon prompt.

Pinging the server works fine (both in loopback and from another box),
and the echoes come right back

Does anyone know why this is happening? Before the kernel upgrade it
worked fine.

TIA.
