We cannot do this for socks5 and we don't really need to anymore (thanks John P. for helping with getting LD_PRELOAD into ld.so which was brought into -current over the weekend and I wouldn't mind seeing it in -stable as I have been running the same code in -current and 2.1R environment). First legally we cannot re-distribute socks5 in source or binary form because of NEC's policy on it. I have been working with Dave Blob, the author of socks5 and have made a port to FreeBSD (however there is one tiny little bug that I haven't updated in the my port that I submitted to FreeBSD), I have had my patches rolled into the socks5 distribution (thanks Dave). FreeBSD is also listed as supported on the Socks5 web page (http://www.socks.nec.com/socks5.html). Second, you don't need to rebuild a binary to socks'ify if it uses shared libs. Dave, designed a intercepting library that can be "preloaded" before all other shared libs and then it will do the socks magic. To set the environment you run this wrapper script with the bin you want socks'ified for example: runsocks ftp runsocks emacs (yes emacs is now socks'fied) runsocks make (in a port directory and now it fetches the dist file via socks! Also this is were the bug is since libsocks5_sh.so was built with -lcompat so sed broke) It should also work if you just set LD_PRELOAD to the special socks lib in you .login and then everything would be socks'ified. So this means we don't need to modify our base telnet, ftp etc. Also Socks5 is way better then Socks4 and is a lot easier to build, it is Socks4 compatible and fully functional for the TCP/IP proxy stuff. This is a great way to share one IP on a home net. The only thing we are missing is socks support for the installation of FreeBSD on the boot floppy. Doug A.
