It looks like rtelnet and socks are using different port numbers for socks.
Sockd is running on port 1080, is something different specified in the
socks.h that rtelnet was built with, or in /etc/services on the client
system?  When the rtelnet is hanging before it times out, what does a
netstat -n show?

This doesn't appear to be related to the lack of DNS.  You should have seen
an immediate "host unknown" or authentication error, if there was a problem
with nameserver resolution.
