Hi,

I am in the process of setting up socks so I can use Mosaic through a
firewall. The wall is a dual homed bastion host with some packet filtering
on the routers.

Anyway, I have two problems. The biggie is that socks seems to want DNS to
be available to be on the *inside* of my firewall. We do not use DNS
internally ( I know, I know :-( ), and currently only my bastion host can
see a DNS server. Is there an easy way around this ?

The other problem is that having built sockd and rtelnet they don't appear
to be talking to each other. In fact when I run rtelnet, sockd does not even
start. I have tried telnet'ing to 1080 to check I have got inetd.conf right
and that starts sockd OK. ( well not so OK :-) )

When I run rtelnet I get:

rtelnet/rtelnet 146.169.2.10
Using SOCKS protocol ver. 4 to proxy server hadrian
Trying 146.169.2.10...
telnet: Unable to connect to remote host: Connection timed out

Is this related to the absence of DNS ? BTW, there is no message generated
on the gateway host.

Any hints would be appreciated,

H

SOCKS proxy server ver. 4.0.
Uses protocol version 4.
