Re: [PLUG] Linux Home VPN How To

or setup your vpn on port 443 :)
Of course.
Normally port 443 is encrypted SSL, so you can't inspect it.
I suppose must proxies don't even try, if they did, in my case they
might see that it
wasn't SSL, so far it's worked with every proxy/firewall I've dealt
with. I've even bypassed
proxies requesting passwords (AD authentication) with just a little
more work. ( And even this
can be done on windows with nothing but Putty )
If you have multiple IP's, I usually setup a subdomain
vpn.hostname.com to point to the
server running ssh ( or openvpn ) on port 443, so the main domain is
free for SSL traffic. This is
of great use to consultants that have to deal with restrictive firewalls
at client sites, or libraries...

however, some networks go so far as to do deep packet inspection on the
traffic itself, in which case this might still get through or otherwise
raise an alarm with the hypothetically competant network admin.
i've been meaning to get around to trying one of those tcp/dns implementations
for such cases (also it's often a way to get around needing to register/pay
with a number of hotspot vendors).
