Since this project is a continuing effort, you are encouraged to check out the WWW page to see if you have the latest software. This is especially true if you find you have problems with the version you presently use. For more information on the NeXT PPP port see: http://www.thoughtport.com:8080/PPP/ -or- ftp://ftp.thoughtport.com/pub/next/ppp/ For more information on PPP in general, you might want to check out: http://cs.uni-bonn.de/ppp/faq.html -and- ftp://morningstar.com/pub/papers/ppp-white-paper.ps.gz -and- http://www.cis.ohio-state.edu/hypertext/faq/usenet/pdial/faq.html (This last is a list of internet providers) See the file ./README for general information regarding PPP-2.2 for all computer systems. See the file ./SETUP for general setup information for all computer systems. See the file ./NeXT/INSTALL for NeXT Specific installation instructions. See the file ./NeXT/README.NeXT for bugs. New to release 0.4.6 (LKS version 4.14) ======================================= * Added a kernel optimization that will reduce the interrupt load on the CPU. This optimization will only work if you use the latest serial drivers supplied by NeXT. You can get these drivers off of NeXTAnswers. The optimization will not work if you use the Mux serial driver. I believe that this optimization will solve many of the kernel panics that people have reported. * Added support for Microsoft's extended DNS negotiation. This will only be of use for people who server PPP clients using Win95, TechSmith Corporation's Foray PPP client (http://www.techsmith.com) for WFWG 3.11, or others whose client supports this mechanism. Thanks to clameter@hur.fuller.edu (Christoph Lameter) for supplying the patches. This patch is totally untested since I don't serve any clients, and if I did I wouldn't admit to running a MicroSloth operating system. * Various minor fixes to documentation and examples. New to release 0.4.5 (LKS version 4.9 release1) ====================================== * This release is based on the third beta release of PPP-2.2 (ppp-2.2b3.tar.gz) by Paul Mackerras. It will probably be the version released along with PPP-2.2. * Some enhancements to the Example ip-up and ip-down scripts. * Several documentation enhancements to support the actual release. * Removed the new locking code. Temporarily, we continue to rely on the old mechanism. * This program runs on Intel, Moto, and Sparc. It apparently runs fine on HP until shutdown. Then there appear to be problems. Due to time constraints, this will have to be corrected as a patch. As usual, this will be available on ftp.thoughtport.com:/pub/next/ppp/. New to release 0.4.4 (LKS version 4.5) ====================================== * The netbuf queueing mechanism was significantly simplified. It is hoped that some HP memory alignment problems were also solved. This may help solve some of the mysterious panics others have seen. * A new locking mechanism was implemented that may simplify the spl() calls. * Memory allocation in BSD Compress code was cleaned up in an attempt to solve HP alignment problems. * Thanks go to Pete French for all the above modifications New to release 0.4.3 (LKS version 4.4) ====================================== * This release fixes some problems regarding HP and SPARC support. It is said to now run on Sparc. I would hope HP also but havn't heard yet. Thanks to Dave Hess for finding the problems for Sparc. * Minor documentation fixes. New to release 0.4.0 (LKS version 4.1 - summerb2) ================================================= * This release is based on the second beta release of PPP-2.2 (ppp-2.2b2). * The default chat is now the one supplied in the beta PPP release. This chat will compile fine using Dev 3.3. However, if you are running Dev 3.2, you will not be able to compile the default chat (POSIX problems). In this case, you may use the old chat (renamed as ./chat/chat.c.3.2). New to release 0.4.0 (LKS version 4.0 - summerb1) ================================================= * This release is based on the first beta release of PPP-2.2 (ppp-2.2b1). * Chat was updated in the new beta. However, because of broken posix functionality under NeXTSTEP (3.2) it will not compile properly. Therefore, the old chat is being used. The newer chat is backed up as ./chat/chat.c.orig. Those with Dev 3.3 may wish to try to compile to see if the posix problems were fixed. * Support for the Microsoft Call Back Configuration Protocol. See the file ./README.cbcp. New to release 0.3.0 (LKS version 3.0 - summera51) ===================================== * This release is the first to be based on the fifth alpha release of PPP-2.2 (ppp-2.2a5). * Major kernel revision. This release attempts to merge the LKS written by Perkins and that written by Prindeville/French. The hope is that this new merged kernel will allow us to maintain one set of sources. This kernel, or a variant thereof, will probably be the one that is released with the PPP-2.2 beta distribution. * Fixed a bug that caused problems with NXFax's capability to determine port usage. * Added support for the Berkley Packet Filter (BPF) and tcpdump. Use of BPF requires special installation instructions. See the installation file for more info. * Fixed a header include problem that kept sources from compiling under NS 3.3 Dev. for m68k. *Sigh* I guess support for m68k continues to falter... :( * Officially changed the name of the log file from: /usr/adm/ppp2.2.debug -to- /usr/adm/ppp2.2.log If you are upgrading, you should change the name of the file in /etc/syslog.conf. Remember to watch out for the tab character and remember to create the initial file. For more information see ./NeXT/INSTALL. This change was done so that the file could be opened from the workspace. There was a naming conflict with the .debug extension. Note also, that this name is a bit different than that suggested in the ./SETUP file. * Fixed a problem with the pppd option 'local'. As part of a5: * Fixed a bug in pppd that would allow service (under some circumstances) to peers who refuse to authenticate. * Fixed a bug with CCP negotiation. * Fixed a bug that caused negotation with an NT RAS PPP server to fail. New to release 1.9 (LKS version 2.1) ===================================== * Support for NS Sparc has been added. Sparc users note, the SUN serial driver in the pre-release was not very robust at high speeds. This has been fixed for the final release. This could cause problems with testing on Sparc. Low bps rates should be OK...like 2400 to maybe 9600 with low system activity. Thanks go to John Landwehr for this work. * Fixed a nasty little bug that degraded performance of multiple interfaces on Intel systems. * Added support for IP address filtering. This allows detection and prevetion of IP address spoofing. Check out the new ./pppexclude directory. Thanks to Lawrence E. Freil for this code. * More support for multiple ppp connections to different hosts. Check out ./Examples/ppp_multiple_hosts.tar.gz. Thanks to Jonathan Adams for this code. * Modified lock file for better UUCP interaction. Special thanks to Kim Shrier for this code. * Fixed the new 3.3 multicast warning. * Improved installation documentation. New to release 1.8 (LKS version 1.3) ===================================== * Moved to ppp-2.2a4, the fourth alpha release from Paul Mackerras . * Fixed a bug that I introduced in 1.7 that could cause kernel panics when BSD compression was used in conjunction with VJ header compression. * LKS Numbering Scheme changed (due to my screwup with a4 and CVS). * Removed support for extra pppd option 'usepty'. Can be done with an external program if desired. * Included the old modified pppstats.c that shows compression statistics. New to release 1.7 (LKS version 1.31) ===================================== * Moved packet compression outside the interrupt handler. Previously, only packet decompression was done outside. * Made many enhancements as suggested by Paul Mackerras. * Fixed a bug that sometimes caused "bad fcs" errors to panic the machine. * Fixed a problem that caused NFS traffic to force compression to exit (and sometimes hang NFS). NFS traffic works properly now (regardless of the buffer size set via the NFSManager.app). * Fixed a timeout problem in pppd that could sometimes cause negotiations to loop endlessly. This fix should eventually make it into ppp2.2a4. * Split code into multiple files for better organization. * Fixed pppstats to show compression ratios on the proper side. Left side is for incoming packets and right side is for outgoing packets. * Added some suggested enhancements to pppd. These suggestions were brought up on the ports mailing list and will probably be included in ppp2.2a4. I added them for the interrim. They basically involve better permissions for running the ip-up and ip-down scripts. They are now run as the effective user-id of pppd. So if you run pppd suid, root, then ip-up and ip-down are run as root. * Corrected several minor documentation problems. New to release 1.6 (LKS version 1.24) ===================================== * Added support for HP-PA systems. Many thanks go to Alain Fauconnet for his efforts in this work. * Added further performance enhancements to the LKS. This resulted in fewer "silo overflows", and thus dropped packets, when operating at high speed (>= 38.4KBS) sustained bidirectional transfers over multiple interfaces. * Updated the installation instructions. New to release 1.5 (LKS version 1.22) ===================================== * Not a real release. Used for distributing tests to HPPA users. New to release 1.4 (LKS version 1.18) ===================================== * Fixed problem that delayed many PPP protcol packets from timely delivery to pppd. * Added compression statistics support for pppstats. * Cleaned up processor priority levels. * Added better support for netbuf queue monitoring. New to release 1.3 (LKS version 1.16) ===================================== * At compile time, you have the option to decompress VJ/BSD packets either inside or outside the interrupt handler. See the DECOMP_OUT flag in ./NeXT/Makefile. The old functionality was to do the work inside the interrupt handler. It is probably more appropriate to do it outside. Thanks to Pete French for discussion on this topic. * Added initial support for operation over pseudo ttys. See the USEPTY flag in ./pppd/Makefile.NeXT. This adds a new option to pppd, "usepty ". If this option is used, pppd will fire up an rlogin session to . You may then use chat as normal to start the remote ppp. Thereafter, the packets flow over the rlogin session. This may potentially be used to start a new ppp session over an open ppp session. * Added enhancements and changes suggested for ppp-2.2a3. This includes some fixes to the BSD compression code that caused it to turn off compression inappropriately under error conditions. * Patched pppd to better support code that sleeps but never wakes in ip-up scripts. Thanks to longyear@netcom.com (Al Longyear) and Bill Hay . * Did more verification with the full version of NXFAX installed. Seems to work flawlessly! Thanks to Rick Damon at Black and White for his help in the matter. * Added a new 'Examples' directory to the hierarchy. This will become a collecting place for user info. New to release 1.2 (LKS version 1.13) ===================================== * The system now supports BSD Packet compression using the new CCP. Of course, both ends must negotiate this option. New to release 1.1 ================== * The system now works with the MuX serial driver V1.5. Probably version 1.4 also. No changes need to be made to the MuX buffer (and DOUBLE_BUFFER) values. * The system now works when NXFax is installed. * There have been some internal optimizations for those who use the NeXT supplied serial drivers. New to release 1.0 ================== * On Intel systems, some ioctl calls did not return the proper value. This turned out to be a bug in the OS. A true workaround has been implemented. The ioctl return value macro is now only used to check for return value errors. Flags are now correctly set without the macro. * Multiple interfaces now work properly. The ioctl fix above solved the problem of a second interface "stealing" the first interface. * lcp-echo-failure works. * We are now using the default pppstats. This was modified to use an ioctl to get information. One less program we have to support. pppstats no longer requires the SUID bit or the loadable. * We are now using the default VJ compression code. Another file we do not have to support. * PPP-2.2 uses a new mechanism for determining when to kill pppd. This should solve the process group problems we have been experiencing. * Compression is not yet implemented. This release should give you the same (but more stable) functionality as the ppp-2.1.2 release. For problems, please mail nextppp@listproc.thoughtport.com.
