FreeBSD Jail Allow Ping / tracerouter Commands

To allow the ping and traceroute commands to be used in a FreeBSD jail, you will need to do the following:

1. Edit the /etc/sysctl.conf file and add the following line:

security.jail.allow_raw_sockets=1

This will enable the use of raw sockets in jails, which is required for the ping and traceroute commands to work.

2. Reload the kernel parameters by running the following command:

# sysctl -f

3. Edit the /etc/jail.conf file and add the following lines to the jail configuration:

allow.raw_sockets = 1
allow.sysvipc = 1

This will enable the use of raw sockets and System V interprocess communication (IPC) in the jail.

4. Restart the jail by running the following command:

# service jail restart <jailname>

Replace <jailname> with the name of the jail.

This will allow the ping and traceroute commands to be used in the jail.

For more information about configuring jail settings on a FreeBSD system, you can refer to the FreeBSD documentation and the jail man page by running man jail on the command line.
