EZJAIL and ping on FreeBSD-11.

[James B. Byrne]

I have read the various 'howtos' respecting this issue and I cannot
see where I have failed to properly follow the instructions. But
clearly I have not done it right.

I have setup a jail named hll124.  it is configured and running.  It
can connect to the network and the Internet without issue. DNS
resolution works fine using local_unbound.

In /etc/sysctl.conf on the host I have this:

# $FreeBSD: releng/11.1/etc/sysctl.conf 112200 2003-03-13 18:43:50Z mux $
#
#  This file is read when going to multi-user and its contents piped thru
#  ``sysctl'' to adjust kernel values.  ``man 5 sysctl.conf'' for
details.
#

# Uncomment this to prevent users from seeing information about
processes that
# are being run under another UID.
#security.bsd.see_other_uids=0
security.bsd.see_other_uids=0
security.bsd.see_other_gids=0
security.bsd.unprivileged_read_msgbuf=0
security.bsd.unprivileged_proc_debug=0
security.bsd.stack_guard_page=1

# Required for Chrome/Chromium
kern.ipc.shm_allow_removed=1

# Add to allow jails to create sockets - 2018-01-31 JBB
security.jail.allow_raw_sockets=1


The host system shows this:

$ sudo sysctl security.jail.allow_raw_sockets
security.jail.allow_raw_sockets: 1


In the ezjail configuration file I have this:

# Allow ping, traceroute and other things 2018-01-31 JBB
export jail_hll124_allow_raw_sockets="YES"


When I connect to the ezjail instance with ezjail-admin console and
run ping then I see this:

# ping 192.168.71.44
ping: ssend socket: Operation not permitted

What else am I missing?
