jails sngrep doesn't work in jail

[joggx]

Installed Freeswitch in Jail but can't use sngrep:

> sudo sngrep
Couldn't activate capture: (there are no BPF devices)

Any one installed fs in Jail before? Thanks.

Have you unhide the bpf device in the devfs.rules of your jail?

Have you unhide the bpf device in the devfs.rules of your jail?

Thanks for the pointer. I added on the host /etc/devfs.rules which doesn't exist yet. Added:

[devfsrules_fusion=10]
add include $devfsrules_hide_all
add include $devfsrules_unhide_basic
add include $devfsrules_unhide_login
add path fuse unhide
add path zfs unhide
add path 'bpf*' unhide

And change the following line in the jail's conf to:

export jail_fusion_devfs_ruleset="devfsrules_fusion"

Then restart the jail but no effect. What's missing here?

With ezjail you must specify a numeric value. Be aware that 10 is often the system value. You'd better assign a higher value like 20 or 100.

Verify what you get with ezjail-admin console fusion and then ls /dev.

Thanks. I changed to 100 and then it works.
