Perl is needed for much of the software below. For Windows, get it from here. A nice Perl tutorial is here
findProxy (was called findProxyNew) scans through a proxy list URL (http, ftp, or local files) to find proxies which work where you are. There is a speed measurement, dupes are removed and IP address and name resolution (forward and reverse) is output for each working proxy. The output can be saved in a file and rechecked periodically. It can also check the proxy.pac file format I posted here before. New: I added command line options for those who don't like to edit the text and CONNECT capability. The CONNECT capability means you can test the proxies which were previously blocked to you from home (see my 'checked public proxies' list). The URL 'counting' function allows checks of all messages in mailing lists, message boards etc.
statProxy diagnoses a proxy:port you feed to it. At the moment, it will tell you if it's alive, what type it is, and the CONNECT options it allows. Use localProxy.pl to set up a local proxy to use these results.
localProxy starts a local proxy for you, using a local port you (may) specify, the proxy host:port to use to do a CONNECT via, and a remote proxy (or service like Usenet news etc.) host:port to CONNECT to. Same as HTTPort, but in Perl. The socket code needs some more work.
sortProxy will merge local files containing lists of proxies and sort them by IP address, removing duplicates. Handy.
findProxyVlad.pl (was called findProxy) scans through recent virtualave proxy logs to find proxies which work where you are. 00/11/6 - Vlad's site is back, for use without payment on the old (pre Oct, 2000) data. 00/11/30 findProxyVlad is now included in the findProxy distribution above.
redir binary for nether.net only!
netcat (binary for windows) is the best all-round network utility for learning and quick tests.
netcat (source for *nix) has the source code, a good manual and some scripts - all of which are not in the windows version
Perl redirector/relay/bouncer/repeater. This puppy should be able to run just about anywhere (where Perl is installed); any ISP, win9*, winNT, win2000. You should be able to run it and play with it on your home computer and then ftp it to an external account when you're confident you know how to make it work. It can be used to redirect TCP connections on any port past port blocking via an open port. It can even be used for web browsing, but in that case it's a bit slow (like using a slow proxy) and it doesn't handle the multiple rapid connections made by your browser loading a complex web page, so you lose some of the small images etc. I'm working on that.
anonymous Perl proxy. A forking Perl proxy which runs almost anywhere (needs LWP). Some basic code to remove identifying info from your web browser.
preforking Perl proxy. A Perl proxy which preforks some slaves to ensure it's response is fast and reliable. This guy works well. Good for heavy-duty browsing on any port you want to get through your firewall blocking. Anonymity code could be easily copied from anonProxy.pl. Update 00/8/25: The new version now includes this by default - set the $ANON variable to 0 if you don't want it (for example, to browse sites which need cookies).
proxy autoconfiguration file. An automatic proxy config file for IE and Netscape for the UAE (but easily modified for other countries). It does automatic failover from a speed-ordered list of proxies, some ad-zapping, and ensures a specified proxy is selected for Outlook Express use when downloading hotmail (to ensure use of a proxy which understands PROPFIND). Points to note:
dual non-anon/anon proxy autoconfiguration file. An automatic proxy config file for IE and Netscape for those who wish to run two proxies (one anonymous, and one non-anonymous allowing cookies). This one has been trimmed to the minimum code to do the job; it doesn't include the code to handle ad-zapping, direct connections etc. The idea is that (in this demo) it looks for requests to egroups and makes the browser use the non-anon proxy to send and receive cookies. For other requests, it uses the anon proxy.
Stone 2.1a is a redirector, proxy, encrypted tunnel etc. The build instructions for use on a Unix shell are here.
teraterm pro is a good, free telnet client. I believe the ssh plugin is also good, so this combination is a suitable free replacement for secureCRT. Another free possibility with ssh is puTTY. Speaking of secureCRT, I didn't say this, but I've heard that deleting HKLM\Software\Van Dyke Technologies from the registry resets the 30 day demo and all.
