i added zabbix in /etc/services

zabbix_agent 10050/tcp # Zabbix ports
zabbix_agent 10050/udp
zabbix_trap 10051/tcp
zabbix_trap 10051/udp

If you cannot telnet to port 10050, then it means you do not have a program running that will listen to commands sent to that port.

Is the zabbix agent running on that computer?

[MrRobbert]

Yes my zabbix agent is running on my home machine

[MrRobbert]

home router 84.25.110.37
internal pc 192.168.1.10

internet

Work Router port forwarding 84.25.110.37 port 10050 to my zabbix server 172.17.6.217


-----------

telnet from zabbix server to localhost on port 10050 = OK

telnet from other PC over the internet like telnet <external ip work> 10050 = OK

Telnet from home telnet <external ip work> 10050 = connection can not be established...

I even have my zabbix agent working at home and my server says its not available

Windows_t/Robbert 84.25.110.37 10050 Monitored Not available Timeout while connecting to [Robbert]

help me...

[pdwalker]

you need to port forward port 10050 on your home router to your internal pc at 192.168.1.10 port 10050

The server needs no port forwarding in this case as the agent is not contacting the server, as the server is contacting the agent.

Also make sure that your PC is not blocking that port with its own firewall software.

I dont have a firewall on my pc right now, and my windows firewall is shut down.

In my smc router have the following configuration:

Nat - Virtual server (You can configure the Barricade g Wireless Router as a virtual server so that remote users accessing services such as the Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade g Wireless Router redirects the external service request to the appropriate server (located at another internal IP address).)

Private IP        Service Port          Type            Enabled 
192.168.1.10       10050           tcp and udp          yes
192.168.1.10       10051           tcp and udp          yes

[MrRobbert]

this is my zabbix_agentd.conf file on my windows pc at home

server=193.173.52.230:10050
LogFile=C:\tmp\zabbixagent.log

[pdwalker]

Change your zabbix_agent.conf file, server line on your windows PC to be
server=127.0.0.1,193.173.52.230 and restart the service

From your PC running the agent, can you "telnet 192.168.1.10 10050" and get a response?

If so, then are you sure that your server IP is definitely 193.173.52.230?

Assuming the external IP address of your PC is x.x.x.x, can you, from the server now "telnet x.x.x.x 10050" and get a response?

...meaning?

Can you, from the windows box, connect to the agent via telnet?

If so, can you connect via the server?

[pdwalker]

Right, just looked in more detail.

#server=193.173.52.230:10050
#LogFile=C:\tmp\zabbixagent.log

Server=193.173.52.230 
ServerPort=10050
#Hostname=193.173.52.230
ListenPort=10051 
#ListenIP=10.239.18.13 
#StartAgents=5 
#DisableActive=1 
#DebugLevel=4
LogFile=C:\tmp\zabbixagent.log 
#Timeout=3

Some of your settings are incorrect. Compare them with the zabbix_agend.conf file from the agent distribution, or fix it by making these changes:

Change:
Server=193.173.52.230
To:
Server=127.0.0.1,193.173.52.230

Change:
ServerPort=10050
To:
#ServerPort=10051

Change:
ListenPort=10051
To:
#ListenPort=10050

and restart the service.
