HOWTO: Automatic PPPOE connection reset in case of packet loss

[s0nic]

I've modified the script from @BennTech (https://forum.pfsense.org/index.php?topic=51714.msg276614#msg276614) to do the following:

• Automatic PPPOE connection reset in case of packet loss

• Own interface down and up sound (only played between 08am-10pm)

• Separate e-mail notification for a successfully restored connection

• Using the Systemlog

It helps when the connection seems to be up and running but no data packets are going through.

#=====================================================================
# pingtest.sh, v1.0.2
# Created 2009 by Bennett Lee 
# Modified by s0nic
# Released to public domain
#
# (1) Attempts to ping several hosts to test connectivity.  After
#     first successful ping, script exits.
# (2) If all pings fail, resets interface and retries all pings.
# (3) If all pings fail again after reset, then reboots pfSense. (currently deactivated)
#
# History
# 1.0.2   Added interface status sound, mail notification, systemlog and PPPOE reset. Disabled reboot.
# 1.0.1   Added delay to ensure interface resets (thx ktims).
# 1.0.0   Initial release.
