host.unix, applicaton.mysql - fails gethostbyname

[petepdxcity]

I just installed/configured b8 on a Fedora FC5 box and two of the
items under configuration->hosts come back with

Name IP Port Status Availability Error Show
Application.MySQL - 15000 Monitored Not available gethostbyname() failed [Unknown host] Items : Triggers : Graphs

Host.Unix - 10000 Monitored Not available gethostbyname() failed [Unknown host] Items : Triggers : Graphs

ossinfo.city - 10050 Monitored Unknown Items : Triggers : Graphs

using agentd vs agent

changed the two conf files

zabbix_agentd.conf:ListenIP=172.21.24.17
zabbix_agentd.conf:Server=ossinfo.city
zabbix_agentd.conf:Hostname=ossinfo.city
zabbix_agentd.conf:ServerPort=10051
zabbix_agentd.conf:ListenPort=10050

zabbix_server.conf:ListenPort=10051

ifconfig eth0 | awk -F'[: ]+' '/inet addr/ {print $4}'
172.21.24.17

checked dns

/etc/resolv.conf
search city
nameserver 10.80.1.15
nameserver 10.80.1.30

dig +short -x 172.21.24.17 @10.80.1.15
ossinfo.city.
dig +short -x 172.21.24.17 @10.80.1.30
ossinfo.city.
dig +short ossinfo.city @10.80.1.15
172.21.24.17
dig +short ossinfo.city @10.80.1.30
172.21.24.17

And I have a question. The 'port' value for Application.MySQL, and
Host.Unix initially was 10000.

Should this be 10000 or 15000 ? I'm at bit confused at this point.

/usr/local/bin/zabbix_agent -c /usr/local/etc/zabbix/zabbix_agentd.conf
/usr/local/bin/zabbix_server -c /usr/local/etc/zabbix/zabbix_server.conf

instead of doing what i should be

i dug in to the code of pinger.c for a few minutes, changed the IP
field from NULL (default?) to the IP of the server, changed to port
to 3306, and it now works.

my question is now, how should it work with out the IP ?

[petepdxcity]

or needs the ip address .. i feel so STUPID

ok back to setting things up
