As you can see, an RPC server is started, and is immediately broken
with
the error:
[03.03.2015 21:03:57] < 49156> net| ERR |Veeam RPC server broken.
We think this is an RPC problem and wonder if it is possible to solve
it,
perhaps with entries in the jails /etc/rc.conf ? Currently we have no
rpc
or lockd/statd entries in the jails rc.conf.
When you see rpc errors in a jail, what does it mean, and how can it be
fixed ?
Thank you.
The error code 92 may be the key. errno(2) tells me it's EPROTO ("A
device or socket encountered an unrecoverable protocol error."). It's
possible that updating the socket keepalive settings requires some of
the socket permissions that jails don't always have.
FreeBSD 8 ... so I suppose that's old-style jails. It might do to set
one of these sysctls:
security.jail.param.allow.raw_sockets=1
security.jail.socket_unixiproute_only=0
Or maybe you're actually using jail parameters? I think those went in 8
(but I'm not sure). If so, and if you're actually using a jail.conf,
try "allow.socket_af" and/or "allow.raw_sockets".
One of those might help. Or neither. But it's at least worth a try.
