echoping appears to compile and run at least on Tru64 (ex-Digital
Unix, ex-OSF/1), Solaris, Linux, SunOS, FreeBSD, IRIX and Ultrix. You
do not have to be root to install it.

Just type "./configure", then "make", and then (as root if necessary),
"make install".

"configure" has some options: 
--disable-http (suppress the HTTP support)
--enable-icp   (add the ICP support, to monitor Web proxies like Squid)
--disable-ttcp  (suppress the T/TCP support which is enabled only if 
         your system supports it - FreeBSD does. See 
         <http://www.kohala.com/start/ttcp.html>)


If 'echoping -h' fails with "tcp_open: unknown service: http/tcp", add
"http" to the services database (typically /etc/services or a NIS map).
Its value is 80. Or, change HTTP_TCP_PORT in echoping.h from "http" to "www"
or whatever is defined on your system (at least AIX or Solaris have the 
problem). A workaround is to specify the port on the command line:
echoping -h / www.mydomain.org:80

If 'echoping -h' replies with a "404" error while the file really exists,
check first that you use the FQDN of the server on the command line
(this is a consequence of the HTTP 1.1 protocol, not a bug in echoping
and this will show only if the HTTP server uses "virtual hosting").
