Network ping with delay, jitter and MOS
The original code was obtained from: http://www.routereflector.com/2014/08/network-ping-with-delay-jitter-and-mos/
The original code has been through a number of authors and iterations.
This next iteration allows:
- a different nagios output (for check_mk)
- rrd code commented out, but can be uncommented for use
- provide a source ip address and source description
linux policy based routing example:
- local interface eth0: 10.1.1.1/30
- other end: 10.1.1.2/30 (this is default gateway)
- local interface eth1: 10.1.2.1/30
- other end: 10.1.2.2/30
- destination host: 10.1.3.1
ip route add 0/0 via 10.1.1.2
ip route add 0/0 via 10.1.2.2 dev eth1 table 6
ip route add from 10.1.2.1/32 lookup 6 priority 100
- The first default route is the main system default route.
- The second default route is placed into table 6 as a special lookup.
- Then a policy is added meaning that anything from 10.1.2.1/32 uses table 6 for destionation lookup
- Table 6 has the default route out eth1 for sending traffic originating from 10.1.2.1/32
so example ping would be:
/usr/bin/python ~/ping/ping.py -c 20 -t 1 -n int_eth1 -s 10.1.2.1 -d 10.1.3.1
The ping will go out interface eth1 with the policy-based route in place. Without the policy based route in place, the ping will go out eth0.
