Redir v.2.2.1 Redir is a port redirector. It's functionally basically consists of the ability to listen for TCP connections on a given port, and, when it recieves a connection, to then connect to a given destination address/port, and pass data between them. It finds most of its applications in traversing firewalls, but, of course, there are other uses. Consult the man page, or run with no options for usage information. Please check the Makefile to see if you need to make any changes to get it to compile correctly on your particular unix flavor. If you would like to remove support for some extended options (for the sake of speed, code size, whatever), change the EXTRA_CFLAGS line in the makefile. The following are supported: -DNO_SHAPER (doesn't compile in traffic shaping code) -DNO_FTP (doesn't compile in FTP redirection support) Please submit patches/comments, etc to: Sam Creasey (sammy@oh.verio.com). ----- I'm thinking of eventually doing a version which never forks, but does one big-honking-select-loop, which probably wouldn't be much of a bother, and would save a good chunk of ram, but then an FD limit becomes quite a real possibility. perhaps an #ifdef selecting the old or new code would help this... though, really, this is a known problem with a lot of proxies, and it doesn't seem to hurt too bad. depends on the MAX_FDS (or whatever that define is. FD_MAX?) on your machine. Wow. The authorship/maintnence for this thing has REALLY gotten mangled. Credits should, logically, go to the following people: Nigel Metheringham <Nigel.Metheringham@ThePLAnet.net> For taking the code I wrote and making it into a more stable sensible, and usable package. Sam Creasey <sammy@oh.verio.com> Original author, but this package would be vastly inferior without Nigel's modifications. Thomas Osterried <thomas@x-berg.in-berlin.de> Added the --bind-addr patch. 22 June, 1999 - Sam Creasey <sammy@oh.verio.com> Bug reports/patches/comments/etc please now to <sammy@oh.verio.com> Current versions can be found at http://oh.verio.com/~sammy/hacks redir is distributed under the terms of the GNU Public Licence, version 2 or later, which was distributed with this source archive in the file COPYING. the files in the getopt/ directory are taken from GNU source code distributed under the same license. These particular files were copied from the GNU package gawk-3.0.3, because it happened to be sitting on my drive at the time. ======================================================================= Redir v.0.7 redir is a tcp port redirector for unix. It can run under inetd or stand alone (in which case it handles multiple connections). Its 8 bit clean, not limited to line mode, is small and light. If you want access control run it under xinetd, or inetd with tcp wrappers. Or you could use the tcp wrapper library to extend it and do fancy access control - if so please let me know. redir is released under GPL. Nigel Metheringham Nigel.Metheringham@ThePLAnet.net 30 June, 1996 ======================================================================= [Original readme from version 0.5] If you liked daemon, you'll LOVE redir! Redir, the fully functional (but only in line mode) port redirector for unix! (yeah! WOOOO!). Basically, it's like tredir. But hacked from daemon. And poorly written. But, hey, it dodges firewalls, and THAT's the important part. I think. Oh, fuck it. Look, it's useful. Good for dynamic IP, too. Trust me, it is. usage: redir [remote-host] listen_port connect_port The syntax is a little clumsy, but it works. compile with make redir or gcc redir.c -o redir comments/bugs/flames to sammy@freenet.akron.oh.us (please, write if you use the program!)
