"on OpenBSD 4.2" I suspect :-)

I also suspect that the rebuild was incomplete, probably because of
missing dependency files (I've been bitten by that myself although not
recently).

Please try "cd /usr/src/usr.bin/ssh && make clean && make
depend &&
make" and see if that resolves the problem.

The other thing to watch out for is object files in the source
directory, if "make" has ever been run without a preceeding "make
obj".
 To account for this, please try this instead of my previous suggested
commandline:

cd /usr/src/usr.bin/ssh
find . -name obj | xargs rm -rf
make clean cleandir
make obj depend
make

Oh, and I see what djm meant by "what platform?": what hardware is
"Other"?

Revert CMSG twiddling

Please try this patch - it seems that some bugs in the kernel ABI were
fixed post-4.3.

Damien, your patch seems to work!!

The patch was applied to the source, then OpenSSH was installed as per
the instruction at openssh.com/openbsd.html for OpenSSH 4.9. It now
just connects like normal.

Thanks.
