2ping (bi-directional ping utility)
|
|
|
|
2ping is a bi-directional ping utility. It uses 3-way pings (akin to
|
|
TCP SYN, SYN/ACK, ACK) and after-the-fact state comparison between a
|
|
2ping listener and a 2ping client to determine which direction packet
|
|
loss occurs.
|
|
|
|
If you would like to quickly test 2ping against a remote listener
|
|
without setting one of your own up, there are several public test
|
|
listeners available. Try test.2ping.net, cromulent.colobox.com, or
|
|
linode-london.mirrors.finnix.org.
|
|
|
|
To run a listener, you can manually start it with e.g. "2ping --listen".
|
|
If you want to start a listener at boot, add a command like this to
|
|
/etc/rc.d/rc.local:
|
|
|
|
su nobody -s /bin/sh -c \
|
|
'exec /usr/bin/2ping --quiet --listen' \
|
|
&> /dev/null &
|
|
|
|
Optional dependencies: Certain command line options to 2ping require
|
|
additional packages.
|
|
|
|
- dnspython: --srv option.
|
|
- netifaces: --all-interfaces option.
|
|
- python3-pycrypto: --encrypt option.
|
|
|
|
The package can include a wireshark plugin for decoding the 2ping
|
|
protocol. This requires your wireshark to have been compiled with lua52
|
|
(not lua, which is version 5.1). See the README for network/wireshark
|
|
for details. If you're not sure about your wireshark's lua version, try
|
|
"ldd /usr/bin/wireshark|grep lua". This will show either liblua.so.5.1
|
|
or liblua.so.5.2.
