<html><head></head><body>I can help out with creating a client and server proxy for this. However I'm not sure how this will work. Here are my key concerns:<br>
<br>
The Gopher protocol doesn't natively support proxy servers. So, connecting to localhost can only tunnel to a single remote gopher server...<br>
Rewritting of gopher menus to change both the host and port will also be needed.<br>
<br>
As a result, I don't think creating a TLS proxy would be feasible, let alone tunneling through an SSH or SSL tunnel.<br>
<br>
The major issue with the gopher protocol is it's menus provide a host and port. While this is also a huge benefit to the protocol, it's also a hurdle when it comes to proxying the protocol itself. Thankfully the menus are easily parsable.<br><br><div class="gmail_quote">On April 23, 2015 3:00:27 PM MDT, James Mills <prologic@shortcircuit.net.au> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

Looking in my OS's /etc/services file it appears there are several<br />
available ports in the 700-799 range:<br />

<br />
As for implementation of the concept, I feel it should be done in a way<br />
that doesn't shut out existing gopher clients/servers.<br />
<br />
Perhaps adopting some sort of external client+server proxy model would be<br />
the best starting point such that, for example, someone with a lynx(1)<br />
browser could install a "secure_gopher" proxy on their computer such that<br />
their now local port 70 requests are SSL-wrapped and sent on to a<br />
corresponding "secure_gopher" proxy server listening on the new gopherS<br />
TLS encrypted port (785 maybe?). Probably it's already doable using<br />
opensshd and SOCKS, just need to pick a port.<br />
<br />
The above approach would not preclude others from basically incorporating<br />
the proxy model into their new clients and servers for an all-in-one<br />
solution.<br />
<br />
For making it officially part of Gopher World I think it means a new RFC<br />
for "secure gopher" or at least adding the spec to the existing gopher<br />
RFC; I don't know which would be easier.<br />
