echoping appears to compile and run at least on Tru64 (ex-Digital Unix, ex-OSF/1), Solaris, Linux, SunOS, FreeBSD, NetBSD, 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) --disable-smtp (suppress the SMTP support) --enable-icp (add the ICP support, to monitor Web proxies like Squid) --enable-ssl (add the SSL support, you will need the OpenSSL library ) --disable-ttcp (suppress the T/TCP support which is enabled only if your system supports it - FreeBSD does. See ) Standard "autoconf/configure" options are supported such as --prefix to set the installation root directory. 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"). $Id$
