Well, first off, SLIP is only a method of transmitting IP packets over serial (asynch) lines. So it sounds like what you're looking for is not just SLIP, which you could tuck under an existing TCP/IP implementation, but a whole TCP/IP stack, complete with applications. Everybody's favorite SLIP implementation for UNIX was done by Rick Adams some years back, and you can find it on NET.UU.NET (uunet for UUCP-land). Everybody's favorite TCP/IP implementation for UNIX is the Berkeley 4.3 TCP, which has been freed by the Regents of UC Berkeley so that it's clear of AT&T licensing. The copyright is still held by them, but you can use the code pretty much however you want. This TCP is an excellent protocol engine but is often a bear to port as it really wants to live inside a Berkelely UNIX kernel. I have appended to the end of this message a copy of an announcement from UCB about the availability of this software. It includes SLIP support. You can also find this online on uunet. - john romkey USENET/UUCP: romkey@asylum.sf.ca.us Internet: romkey@ftp.com "Some people walk on water/Some people walk on broken glass/Some people walk round and round in their dreams/Some just keep falling down." Laurie Anderson From: bostic@OKEEFFE.BERKELEY.EDU (Keith Bostic) Newsgroups: comp.bugs.4bsd.ucb-fixes Subject: V1.73 (BSD Networking Software, Release #1) Message-ID: <8812070154.AA18358@okeeffe.Berkeley.EDU> Date: 7 Dec 88 01:54:54 GMT Organization: University of California at Berkeley We are happy to announce the availability of the first release of the BSD networking software. It consists of the standard user level applications, (along with their manual pages and some related documentation) and some kernel and C library support. It should be noted that this software has only been tested for compilation and operation on 4.3BSD and 4.3BSD-tahoe. A complete list of files is attached to this message. The TCP and IP code is approximately the same as that recently made available via the ARPANET and Usenet. Several new algorithms are used in TCP, in particular Van Jacobson's slow start and dynamic window size selection algorithms and Phil Karn's modification to the roundtrip timing algorithm. These changes increase throughput and reduce congestion and retransmission. Several fixes were made in the handling of IP options and other gateway support. This software suite is copyright The Regents of the University of California and may be freely redistributed. No previous license, either AT&T or Berkeley is required. The release costs $400.00 US.

Try looking on 'uunet.uu.net' in the Berkeley (4.3BSD) subdirectories. I know there are object modules for slip on this node, and I beleive that most of the berkeley networking source codee for 4.3 is there as well.
