Hi,

I have connected 2 small office, with 9.6k leased line
with modem using ppp with linux system on both ends.
It takes lots of time for connecting, ftp /telnet
etc...Once connected things work fine.

Where as from remote end to my local things is fast.

What could be wrong?

Thanks.

Reverse lookup. Unix/Linux attempts to resolve IP addresses to names for incoming connections. If you are not pointing to a DNS server that has the remote machine listed in both forward and reverse lookup zones, simply add the remote machine to your /etc/hosts file. Good luck.

yepp, the mentioned reverse loockups are also an issue!

i think your problem are ident lookups on port 111. If you use a firewall, then add a REJECT instead of a DrOp statement to it. If you even don?t have a ident service on you boxes also add the drop line to your fw config or disable ident lookups on the conntected box.
