Unhappy delayed responses at almost all ports


I've set up my new Debian for a little home server. All is working fine, but a problem:

If I connect from an other machine over/with ssh, vnc, nfs to this server it takes over a half minute before I get a response. After the first response all works fine and quickly.

I use a PCMCIA-ethernet card in an 600 mhz celeron notebook. Outgoining connections and all over localhost are all without any problems.

A ping is successful (0.15 ms) and also an http-request from outside is without any delay.

I searched a long time, but found nothing that sounds like that.


PS: A year ago, I set up SuSE linux and a usb wlan stick on the same notebook and there were the same problems ... but with all ports.

Sounds to me as if the box is having DNS problems. It must be trying to to a reverse DNS lookup when you connect, and wait for that to time out before it continues letting you connect. Take a close look at your /etc/resolv.conf, or look at the proper manuals to find out how to disable this check for the services in question.

I work without any DNS, only Static IPs and a /etc/hosts table. (for my network)

content of resolv.conf

May there is sth. like "search" missing? I'll try and write later.
While wating for a response set also FC3 up, the first time it works great but after some reboots, the same problem.



Today I tried to access via ssh, first times the same problem, but while trying it the 5th or 6th time it was faster ... also from other machines... Can't explain ... so reinstalling my debian, thanks
