I would like to expose a web server running on a personal laptop elegantly and securely. This laptop is not always connected at the same point, so a static IP will not do. I am also familiar with dynamic dns however my laptop will sometimes be behind firewalls over which I have no control.
A solution which I believe is quite elegant involves ssh'ing from the laptop to my external, statically IP'd host. I would then need to notify the externally running httpd that a tunnel is now available, and then use something like the ProxyPass directive to seemlessly forward client requests to the laptop. So far I have been unsuccessful in getting this to work - using wget on the external server I get a connection refused. I have found a variety of web sites on mod_proxy, ssh tunneling. I have even found some sites that describe (sort of) how to proxy over a tunnel initiated by the external host. It would be handy to know how to do some low-level network troubleshooting. I am familiar with netstat but I'm not sure what I'm looking for. The external host should have local port 8080 open. Somehow, sshd causes this to happen when ssh connects with certain command line parms. I'm not sure how to check this apart from connecting and running wget http://localhost:8080 and hoping it hits my laptop. If this works, I think the method would be very useful for many debian users wanting to expose their own services behind an inexpensive web hosting provider. The benefits over DDNS are several.
