xymoncgimsg.cgi - CGI utility used for proxying Xymon data over HTTP
is the server-side utility receiving Xymon messages
sent by the xymon(1)
utility over an HTTP transport. The xymon
utility normally sends data over a dedicated TCP protocol, but it may use HTTP
to go through proxies or through restrictive firewalls. In that case, the
webserver must have this CGI utility installed, which takes care of receiving
the message via HTTP, and forwards it to a local Xymon server through the
normal Xymon transport.
The CGI expects to be invoked from an HTTP "POST" request, with the
POST-data being the status-message. xymoncgimsg.cgi
simply collects all
of the POST data, and send it off as a message to the Xymon daemon running on
IP 127.0.0.1. This destination IP currently cannot be changed.
The CGI will return any output provided by the Xymon daemon back to the
requestor as the response to the HTTP POST, so this allows for all normal
Xymon commands to work.
will only send data to a Xymon server through the
loopback interface, i.e. IP-address 127.0.0.1.
Access to the CGI should be restricted through webserver access controls, since
the CGI provides no authentication at all to validate incoming messages.
If possible, consider using the xymonproxy(8)
utility instead for native
proxying of Xymon data between networks.
