[Xymon] Test http : when firewall between xymon server and host

Hi,

According to my logs, the http check is realized by the Xymon server (xymonnet part as far as I remember).

Hello,

I do often things like that (on hosts.d/mytest.cfg)

172.16.y.xxx host31
#http://www.toto.com=/172.16.y.xxx

but recently on new hosts, this test is red but if i do that (on the host to check)

curl -sIL -H "Host: www.toto.com" "http://localhost"

all is ok

So does the test is start from the server ?

1/ If yes, is there a way to execute the same test in localhost ? It's because the only open ports from Xymon Serveur to host are

• tcp/22
• icmp

And there's no way to open more.

2/ if no what's wrong
