The utility ProxyPing
is a simple tool to ping servers behind a firewall that will not let ICMP packages
through. It provides a HTTP server answering to ping requests and returning the ping delay as a HTTP text result. The
tool will have to be deployed on a server behind the firewall that can be reached by a configurable TCP
connection (defaulting to port TCP 6666).
Suppose the tool is deployed on server my.proxy.behind.wall
and the server to be pinged is called some.other.server
the required HTTP query will have to look like this:
http://my.proxy.behind.wall/api/ping?host=some.other.server
