I am trying to get IPsec working between my VAX (10.0.0.7) and my Alpha
(10.0.0.5). For this I am using NetBSD 1.5 (release version, with IPSEC
and IPSEC_ESP), and the latest racoon from pkgsrc, racoon-20010418a. I
am trying to follow the procedure as outlined in the Daemonnews article
at http://www.daemonnews.org/200101/ipsec-howto.html . I increased the
timeouts significantly, because the VAX is fairly slow, especially when
printing all the debugging output.
I am asking here before I report to KAME's send-pr system.
There seems to be a problem that occurs on the VAX side and not on the
Alpha side, despite identical configuration on both sides. I copied the
configuration files from one machine to the other (and I am using
swapped IP adresses in them of course).
To start with, I don't know much about the details of what I am doing, I
am simply seeing asymmetry in INFO output of racoon, with an ERROR
message on the VAX side only:
ERROR: pfkey.c:217:pfkey_handler(): pfkey UPDATE failed: Invalid argument
I was naughty, and patched racoon to ignore the condition, which results
in the output shown at the end. (Once, I saw the same message on the
Alpha side, but I could not reproduce it)
The output of setkey -D looks nicely symmetrical on both machines after
this: entries for both directions are shown. Well, sometimes. In more
recent attempts, the VAX only shows one entry (10.0.0.7 10.0.0.5, the
info for outgoing data I presume). Tcpdump while doing a ping shows ESP
packets flowing from the VAX, and back, but ping itself reports 100%
Also, interrupting racoon seems to give a crash and core dump most of
the time, just on the VAX, not on the Alpha.
