Some issues concerning DNS. If you use your "local" DNS and resolver, it is better to append a "forward first" and "forwarders your.xDSL-dns.provider.ip-number" directives in /etc/named.conf or equivalent (i suppose you are using Bind 9.0) On Thu, 2003-02-27 at 09:25, André Heßling wrote: > > I am using Linux (Red Hat 8.0 with Kernel 2.4.20) on a second computer. > It's going online using WinRoute on a Windows computer (NAT). > > The Linux PC has IP address 192.168.1.103 (name: linux) > The Windows PC has IP address 192.168.1.100 (name: andre) > > Gateway and /etc/resolv.conf are configured correctly. > > Everything works fine but when I want to establish a connection with > telnet on the Linux computer for example to google.com, the > establishment lasts about 10 sec. > But then it works fast. > > The command is: > telnet google.com 80 > > The resolve via "host google.com" is usual fast. > And if I telnet the IP address of Google instead of the hostname, it > works fine, too.

Logs, show us the logs. Ping everything and note the ping statistics. A socket connection is better than a mis-configured resolver or DNS. > > The delay also occurs when I do a "telnet localhost 22".
