Also, for whatever reason nice per jail configuration that Scott Lambert
pointed to did not work for me, so I still had to stay with allowing raw
sockets in all jails on my boxes... Could you try that less elegant
configuration I mentioned:
# execute the command:
sysctl security.jail.allow_raw_sockets=1
# restart jail in question
- and see if you still have raw socket problem for users in that jail.
Thanks.
