But still unable to telnet to the nameserver over port 53.
Can anybody provide any pointers to what I can try next?

tcp-env
tcp-env(1) General Commands Manual tcp-env(1)NAME
tcp-env - set up TCP-related environment variables
SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ]
DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several
environment variables as described in tcp-environ(5), and runs program with the given arguments.
Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if
PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
whether the input is a TCP connection.
OPTIONS -r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host.
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
-ttimeout
Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
