I’m having issues with xymonfetch.
I have 2 xymon proxies, that also have the xymon server running as a backup to the main server on port 1985. The proxy sends to the main server on port 1984 and to itself on port 1985.
I’m trying to add 2 new machines as clients of these proxy servers. They are outside a firewall that I don’t want to open, so I’m doing a fetch. Xymon-client is running on 1984, and msgcache is running.
Client clientlaunch.cfg:
*[msgcache]*
*# DISABLED*
ENVFILE $XYMONCLIENTHOME/etc/xymonclient.cfg*CMD $XYMONCLIENTHOME/bin/msgcache --no-daemon--pidfile=$XYMONCLIENTLOGS/msgcache.pid*

*10.6.0.15 remoteclient2 # pulldata=10.6.0.15:1984 *
**
I have a third xymon server, the development server, which is not a proxy, and the server runs on 1984. This pulls the data just fine from the remoteclients.

The xymonfetch.log file gets these errors:
*2015-11-11 15:56:24 Connection lost during connect/write to 10.6.0.14:1985 (req 27): Connection refused*

*The proxy servers are 4.3.10. The development server is 4.3.21. The main server is also 4.3.10, and it runs a fetch without issue, to other clients.*
**
*The clients are 4.3.10 (CentOS 5) and 4.3.21 (CentOS 6). *
**
*I am working on upgrading the proxy servers in OS (CentOS 5 -> 6) and Xymon (to 4.3.21). But not quite there yet. Another subject, but sending data from a proxy to another proxy does not work. So, when I have everything else, I may end up putting it in place, and hoping the proxy works….*

*Any ideas here? It seems like such a simple thing. *

Does seem a bit odd. Either xymonfetch is not paying attention to pulldata, or it seems to want to reconnect back to the original host incorrectly for the client (config) reply. Can you try --debug on the xymonfetch process, or alternatively strace it, so we can see at which phase of the transaction that write is failing at?
On the second issue, I know xymonproxy is capable of doing proxy-proxy submission, as we used it pretty heavily for that (albeit with caveats at scale when dealing with TCP packet loss), does a 'ping' make it through at all when going on that path?
