[plug] Any idea's?

[Bill Kenworthy]

Here's something that has me puzzled.  I can set up a "httptunnel" using
my local machine/proxy and connect to telnetd/sshd etc ok.  When I try
and use an external proxy (any one), ethereal shows identical packet
data for a connect, but the localhost socket refuses to acknowlege the
connection - I can see the data going in, but nothing coming back.  No
responces are logged (hosts.deny, logfiles etc have been checked, no
reason shows, just silence).  What security mechanism (I presume) could
Mandrake be using that might prevent a program from creating a localhost
connection to a telnet server?

* for those not familiar with it, httptunnel sets up a tunnel using http
get/put requests to transfer data so it is possible to say telnet to the
tunnel input and have the tunnel output do a connect to port 23 on the
machine where the output appears.  i.e.

telnet localhost 1111  (port on local machine)
tunnel created via proxy.somewhere to remote machine port 1234
tunnel output sets up a connection to localhost:23 (on remote machine)
and forwards data.
