At present, I have a work-around. Instead of using
bin/xymon to send > messages, I'm using curl to post the message file to > https://server.domain.com/xymon/upload.php. On the server side, the > upload.php script simply drops the message file into xymon's incoming > stream, just as if it were delivered over the net by bin/xymon.
Good idea. I almost can copy this approach.
The client side has the server's CA cert to validate the connection > and the data flow is encrypted in transit. I could use client certificates as well.
But I think this approach only works for Linux xymon client, since curl is readily available.
Preparing curl for other Unix(say HP-UX) and Windows will be a big challenge.
