        Well I did this

        firewall-cmd --permanent --add-port=10051/tcp
        firewall-cmd --permanent --add-port=10050/tcp

        So I assume yes?

        How exactly would I check, sorry

        Did you

        firewall-cmd --reload ?

        Edit: That's a good question... I'm not sure about how to do that with firewalld.

        sudo firewall-cmd --permanent --list-all

              Anyone have anymore ideas on what I should try to get the windows agent to communicate with my server?

              Want any config files?

                    @Sparkum Finally got a windows vm setup and got the agent working.

                    alt text

                    This are the steps I took to get it working:

                    Download windows pre-compiled agent:
                    http://www.zabbix.com/downloads/3.0.0/zabbix_agents_3.0.0.win.zip

                    From an elevated cmd promt
                    I went inside the extracted folders to install the zabbix agent as a service:
                    zabbix_agents_3.0.0.win\bin\win64\

                    Executed the following command to install the service and point to the config file:
                    zabbix_agent_d.exe --config "..\..\conf\zabbix_agentd.win.conf" --install

                    Now we need to edit the config file to point to our zabbix server:
                    zabbix_agents_3.0.0.win\conf\zabbix_agentd.win.conf

                    Modify the following options:

                    Server=Zabbix Server IP Address
                    ServerActive=Zabbix Server IP Address
                    Hostname= FQDN of windows host
                    

                    Went back to the bin folder and started the service:
                    ..\zabbix_agents_3.0.0.win\bin\win64\zabbix_agent_d.exe --start

                    Allow the zabbix_agentd.exe executable throught the windows firewall.

                    Add the host to the Zabbix Server
                    alt text

                    In new host settings add:

                    # HOST TAB 
                    Host name = FQDN of your windows host
                    Groups = Use a preset group or create a new one
                    Agent Interfaces = IP address of Windows Host
                    Enabled =  Checked.
                    
                    #Templates Tab
                    Link new templates = Template OS Windows
                    

                    Save your newly created host and wait for a couple of minutes to get it talking to your server
                    alt text

                    Its done and reporting =).

                      I'm getting closer!

                      So the only thing I did from what you wrote was

                      Hostname= FQDN of windows host
                      

                      But after that I have a red Z!
                      Progress!

                      Currently getting

                       Get value from agent failed: ZBX_TCP_READ() failed: [104] Connection reset by peer
                      

                      I'll try to google my way through that now!

                      Thanks

                        I just upgraded my install from Zabbix 3.0.5 to 3.2.1 painlessly.

                        yum -y install http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
                        yum clean all
                        yum -y upgrade
                        

                        Only poked around a little but everything seems to be working.

                        I only have 6 devices reporting in on this for the moment. Been meaning to get this fully functional for months now.

                          Same here I really need to wipe mine and re-do it all and get some better info out of it like Performance and IOPS on the servers etc, instead of just ping to see if up or down

                            Had to modify the instructions a bit to handle SELinux. The below have been added to the first post already.

                            Install SELinux tools.

                            yum -y install setroubleshoot setools
                            

                            After your system is up and running, reboot. You should hopefully have a problem with SELinux blocking a couple of things.

                            [root@zabbix ~]# sealert -a /var/log/audit/audit.log | grep zabbix
                            SELinux is preventing /usr/sbin/zabbix_server_mysql from using the setrlimit access on a process.
                            <snip lots of text>
                            SELinux is preventing /usr/sbin/zabbix_agentd from using the setrlimit access on a process.
                            

                            Now that these errors are in the audit log, we can set up SELinux to allow it.

                            If anyone knows SELinux well enough to create the policies needed without waiting for a fail, just let me know. I will be happy to update these instructions.

                            ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver
                            semodule -i my-zabbixserver.pp
                            ausearch -c 'zabbix_agentd' --raw | audit2allow -M my-zabbixagentd
                            semodule -i my-zabbixagentd.pp

                              Did anyone get Zabbix working over SSL? I'm getting a 403 error when I try to setup the certificates.

                                I'm planning to do this and I think the best way (from what I've read) is to use a proxy to handle the SSL cert for you

                                  I know Scott loves his LANLess design, so maybe my question is meaningless, because to him there is no internal?

                                    Yes, you could setup a proxy on the same box as Zabbix.

                                        I wasn't aware. I've got the SSL "working" kind of but need to troubleshoot my virtualhost declaration as to why it isn't working.

                                          Did anyone get Zabbix working over SSL? I'm getting a 403 error when I try to setup the certificates.

                                          I'm planning to do this and I think the best way (from what I've read) is to use a proxy to handle the SSL cert for you

                                          Does this mean proxying internal connections as well?

                                          I know Scott loves his LANLess design, so maybe my question is meaningless, because to him there is no internal?

                                          Yes, you could setup a proxy on the same box as Zabbix.

                                          Zabbix makes their own Proxy as well just as a side note

                                          I wasn't aware. I've got the SSL "working" kind of but need to troubleshoot my virtualhost declaration as to why it isn't working.

                                          Wish I could help more. This is something I am doing in the very near future though.

                                            I'm about setup Zabbix with above script on CentOS 8.

                                            Do I just need to update the link below, to get latest Zabbix version? all remains same?
                                            http://repo.zabbix.com/zabbix/5.0/rhel/8/x86_64/zabbix-release-5.0-1.el8.noarch.rpm
