hosts and dns : error gethostnyname()

[dsipe]

hye,

i create a host with its DNS alias instead if its @ip.

when server start polling, i've got the message "gethostbyname() failed [ Unknown host] under the "Configuration -> Hosts" menu.

Pinging the alias name on the zabbix's server work fine.

What's wrong ??

Try isolating this from zabbix and see if you can resolve DNS from some simple apache or php scripts.

If I was to guess, based on the symptoms, you can't resolve DNS from apache because you have apache in a chroot jail without the libraries needed to resolve DNS.

i find the source of the problem: in the database, the length of the IP adress field is limited to 15 char.

When creating my host, i try putting the all alias name [ serveur.eram.loc ] and this was truncated to serveur.eram.lo ...

that was the reason.

Can't this field by extend in future release ?

serveur.eram.loc does'n sound like a IP address!

right, but searching in the forum, i found a post telling that to use the DNS name of a serveur, you need to put it in the @ip field.

That's not correct ?
