ocserv startup script on FreeBSD

Fri Aug 14 11:55:56 PDT 2015

Hi people,

We have some problems with the ocserv rc script, here it is the error
output

# service ocserv onestart
Starting ocserv.
Parsing plain auth method subconfig using legacy format
Setting 'plain' as primary authentication method
setsockopt(IP_RECVDSTADDR) failed: Invalid argument

Any thoutghs?
