Hi all,

I have databases and webpages in my hosts.cfg like this..


0.0.0.0        Oracle_Enterprise_Manager # prefer noping noconn https://ictoem01.stanwell.com:7801/em/console  # Obviously a web page

0.0.0.0           soapro # prefer noconn  #  This is an oracle database which I have tests sent to.


What I find is that even with noconn, it still attempts to resolve the server name ie Oracle_Enterprise_Manager


I have managed to fix this by modifying xymonnet.c on line 839

From this...


if (!h->testip && (dnsmethod != IP_ONLY)) add_host_to_dns_queue(h->hostname);


to this


if (!h->testip && !h->noconn && (dnsmethod != IP_ONLY)) add_host_to_dns_queue(h->hostname);

Any comments or possible breaking of Xymon??

If my interpretaion is what is expected for the noconn test maybe Henrik could put this in as a bug fix  :)

Thanks
