+Some notes regarding the FreeBSD port of SKIP
+December 8, 1997
+
+- Much of the non-man page documentation has NOT be patched to reflect
+ the different locations of files, etc. The main difference is that the
+ original version of SKIP puts everything under /usr/skip, whereas the
+ FreeBSD port has put it under @@PREFIX@@. This documentation can be
+ found in @@PREFIX@@/share/doc/skip.
+
+- Thanks to Stephanie Wehner, skiphost now takes a new argument for specifying
+ the source address for encrypted packets. This allows encrypted packets
+ that are being tunnelled between two routers to have source and dest
+ IP addresses of only those two routers. This reduces firewall complexity
+ in many cases. From her description:
+
+ This adds another command line option to skiphost, namely
+ -f <source address> . Every packet going out to the other host
+ will then have this source address in the packet.
+
+- SKIP is applied to packets *after* any ipfw(8) filtering is applied.
+ This is true for both incoming and outgoing packets. Note that SKIP
+ has its own access control functionality.
+
+ One way to deal with this is to do the following:
+
+ - Setup ipfw as you normally would to restrict access to your machine.
+ - Add additional ipfw rules to allow SKIP related traffic:
+ - ipfw add 10 allow 57 from any to any
+ - ipfw add 10 allow 79 from any to any (if using SunScreen mode)
+ - ipfw add 10 allow 50 from any to any (if using raw ESP/AH mode)
+ - ipfw add 10 allow 51 from any to any (if using raw ESP/AH mode)
+ - ipfw add 10 allow udp from any to <your-address> 1640
+ - ipfw add 10 allow udp from <your-address> 1640 to any
+ - Set the default rule for SKIP to be to allow access.
+
+- Skipd will logs via syslog(3) instead of logging directly
+ to /var/log/skip.log as before, using the LOG_DAEMON facility.
+
+ You may want to redirect this output to its own log file.
+ This is done by the following steps:
+
+ 1. touch /var/log/skipd.log
+ 2. Edit /etc/syslog.conf and add these lines at the end:
+
+ !skipd
+ *.* /var/log/skipd.log
+
+ 3. Edit /etc/newsyslog.conf as appropriate
+ 4. Restart syslogd
+
+- Each time skip is started (at reboot time), the skiphost
+ output is written to /var/log/skiphost.log. You may also
+ want to add an entry to /etc/newsyslog.conf for this one
+ as well.
+
+- Users of skip should subscribe to the SKIP mailing list
+ by sending an email to "majordomo@skip.org" containing
+ the line "subscribe skip-info".
+
+- If you have trouble:
+
+ - If there is a problem with the port itself (e.g., it won't
+ compile on your system), use send-pr(1) to send a problem report.
+
+ - If you are having trouble with SKIP configuration, use,
+ compatibility, etc., send your questions to the SKIP
+ mailing list: skip-info@skip.org (you should subscribe
+ to it first).
+
+Thanks,
