Title: Slow Connection
Post by: Stryker on 18 November 2002, 03:10

At home I have a private network. Not connected to the internet except individual dialup accounts. there is a domain server (Samba) serving user accounts and a dns server just for the joy of learning about it. Everytime anybody connects to it, it give about a 20 second pause before anything is done. This happens through smb, ftp, http, dns, telnet, sendmail, and pop3. I've considered adding an entree in the /etc/hosts for itself but i do not know the format. the domain is rocmud and the server is "server1". How would I go about solving this, and if it is the /etc/hosts then what is the format for entering stuff into it?

Actually the problem is likely that the server is trying to reverse resolve the client names. If you put the IP address (and a name) for each of your clients and things speed up, you'll know that's why. Another common thing is to have /etc/nsswitch.conf properly configured. I usually have:

hosts: files dns

Might want to give it a shot. For security a lot of services want to be able to reverse lookup the client IP for logging and other reasons.

Thanks, all goes well now. Although I'm sure something else will arise, it's just no fun without things to fix.

I don't put names in my /etc/hosts. I use a reverse DNS zone in my DNS server.
