Greetings FreeBSD community,
OS: FreeBSD sun 12.2-RELEASE-p1 FreeBSD 12.2-RELEASE-p1 GENERIC amd64
I am trying to build a netgraph vnet jail with support of official jng
script that comes with FreeBSD and developed by Devin Teske.
jail.conf file
netgraph {
devfs_ruleset = 13;
enforce_statfs = 2;
exec.clean;
exec.consolelog = /var/log/bastille/netgraph_console.log;
exec.start = '/bin/sh /etc/rc';
exec.stop = '/bin/sh /etc/rc.shutdown';
host.hostname = netgraph;
mount.devfs;
mount.fstab = /usr/local/bastille/jails/netgraph/fstab;
path = /usr/local/bastille/jails/netgraph/root;
securelevel = 2;
vnet;
vnet.interface = e0b_bastille0;
# exec.prestart += "jib addm bastille0 re0";
# exec.poststop += "jib destroy bastille0";
exec.prestart += "jng bridge netgraph re0";
exec.poststop += "jng shutdown netgraph" ;
}
When I start the jail, netgraph subsystem raise the following exception
ngctl: send msg: No such file or directory
jail: netgraph: jng bridge netgraph re0: failed
I tried also to create the netgraph bridge with not using jng script
ngctl mkpeer re0: bridge lower link0
ngctl: send msg: No such file or directory
From what I found it looks it used to work on FreeBSD 11.x and stopped
working in version 12.
Any thoughts ?
Please advise
Cheers,
Petru Garstea
