I've been using Ubuntu as my main system since 7.04 with a few short breaks using Windows or Fedora because of temporary hardware/software incompatibilities. I support FOSS projects like Ubuntu for a number of reasons but the biggest one is that the software works and it works well--often better than the non-free alternatives.

I'm no guru but in my travels I've learned a thing or two about using/debugging/fixing problems in Ubuntu which I'm always happy to share with the community. If it hadn't been for the help I've received from the Ubuntu community over the past few years I probably wouldn't have gotten past my first month of using it much less to where I am today!

comment local development LAMP server: routing external requests through SOCKS proxy
I'll give proxychains a try. I know my remote server works for remote DNS resolution because I've always been able to do this with Firefox and Chromium using their built in socks5 support which both support remote dns resolving, in firefox as an option and in Chromium by default. tsocks however didn't seem to capture the dns packets with firefox, which makes me dubious it would for the apache server. maybe proxychains does a better job of this....

comment local development LAMP server: routing external requests through SOCKS proxy
I can get some limited functionality (I'm testing with a tsocks-ed version of firefox) by putting the hostnames/IPs of sites I know are blocked into my /etc/hosts file, but sites such as youtube and facebook are so complicated these days and host their content on a wide (and constantly changing) range of sites (try watching the loading/looking up/connecting/etc. messages when you load a youtube video) it would take forever to find all the blocked hostnames and add them to my /etc/hosts file. So, currently I can browse youtube fine, but videos won't load... oh well, back to the drawing board!

comment local development LAMP server: routing external requests through SOCKS proxy
thanks for the advice. unfortunately my problem is a lot more complicated than I originally thought it was. In addition to url and packet filtering China also uses DNS filtering. This is a problem because DNS lookups are UDP requests and only TCP requests get sent through the ssh tunnel (not a problem with firefox or chromium because they have options to route dns through the proxy--doubt apache has such). There is a solution (see hekate.homeip.net/tag/tsocks) using the program socat to convert the lookups to/from UDP on either end of the tunnel but I can't get it to work correctly.

comment How does one recreate a custom application launcher that takes command line syntax and even perhaps parameters?
On second thought, definitely follow the directions in the answer below. Editing the files in /usr/share/applications/ directly is not a good idea for a number of reasons (unless you a)specifically want the custom launchers to be the default for all users on your machine, and b) backed up the files first.)

see this question for example, which suggests a socks global proxy is impossible with Xubuntu: askubuntu.com/questions/77509/…

thanks for your response. Your right, I wasn't very clear about this. I have no problem making the SSH tunnel itself, it's just configuring it as the global socks proxy that is giving me trouble. Xubuntu doesn't come with ubuntu's Network Proxy GUI, and all of the solutions I found via googling were only for http and ftp proxies and suggested it is impossible to set a global socks proxy (which I don't believe). They suggested using tsocks, but I'm unsure how to/if I can use tsocks with apache5 without breaking it.
