[9fans] Venti on OpenBSD: vtversion: bad format in version string

[9fans] Venti on OpenBSD: vtversion: bad format in version string

[Grant Mather]

Hello everyone,

I am new to the list and to Plan 9. I have been trying to set up an
OpenBSD venti server for a few days now, but to no success. My
intention was to use it as the default venti server for my Plan 9
machine.

I partitioned the disk using fdisk to create one large OpenBSD
partition, and then created two paritions with disklabel, one for arenas
and one for isect. I followed the wiki page for setting up venti, and
have been able to get it working on Plan 9 and other OSes, but not
OpenBSD.

Using plan9port-20120508 that is provided with OpenBSD seems to have
venti working properly on the system, but it does not work across the
network, when trying to connect with vac/unvac to the server with a
different OS, I invariably get "vtversion: bad format in version
string".

Using the most up to date plan9port-20140107, I get the same vtversion
string when connecting from other OSes, and venti doesn't seem to even
work on the server, I in turn get "vac: could not connect to server:
Connection refused".

Any help would be much appreciated it, I don't know what's going on.

One suggestion is to use normal files for venti and see if that works.

Have you tried diffing the two versions? Might tell you something. I
use p9p venti on FreeBSD for my plan9 installs with no trouble so far.

One more suggestion is to look at the data on the wire and compare
with a working venti.

It appears to work fine with normal files, and I actually did manage to
get it to work with disk partitions, however I noticed two strange
behaviors. 1) when using vac on the OpenBSD machine it would not
recursively vac' directories, however it did work properly over the net
on Plan 9. 2) However, after reboot I got the same error message and it
no longer worked, even locally on the OpenBSD computer.

I tried diffing them, and the only differences were in VTMaxLumpSize, I
dunno if it makes any difference, regardless neither the 2014 or the
2012 version worked, so I guess I'm out of luck.
