It goes PING!

If you're like me, you have a bunch of trusty (and rusty) shell scripts that you reach for when doing things like testing a new load balancer.

Enough of that! igp (It goes PING!) is a simple command line utility for testing services with a range of common protocols: ICMP, UDP, TCP, HTTP/S, LDAP/S and so on.

This is nothing earth shattering I know, but it's nice to have simple cross-platform (since it's ruby) tool that does all the common protocols in one. Thankfully, most of the work has already been done by the net-ping library - igp really just provides a sleek command-line wrapper.

The only dependency is ruby+rubygems. Just:
gem install igp
And then you are ready to capture traces, for example:
# ^ ICMP assumed by default. This is the same as:
igp icmp://



igp tcp://
igp udp://

igp ldap://
igp ldaps://
