Using Zabbix version 4.2.6 I get the alert Zabbix agent is not available with a zabbix proxy that i have properly installed,configured and registered. I tried to reboot the proxy machine, several times but nothing works right or at least , the alert still stays on the dashboard.
The ip by which the proxy is registered is the loopback one: 127.0.0.1.
Would it be possible to be an error of the agent
The operating system of the zabbix proxy that is being monitored is Ubuntu Server 18.04

I am using Jenkins on MacOS (Monterey) and I want to be able to access my Jenkins from any (outside) network using my ip address.
I have updated the --httpListenAddress to 0.0.0.0 and restarted Jenkins.
I have checked for port 8080 to be open to inbound traffic.
I have been able to access this Jenkins from devices on the same network but not from an outside network.
I was able to achieve everything I wanted when using an AWS EC2 instance (by adding security group rules) but not able to do the same for a local Jenkins on my machine.
Any help/advice would be great! (Maybe without using a 3rd party service?)
Thank you.
I am trying to set up OpenVPN so that I can access machines inside an Azure subnet from my pc which is outside Azure.
I have successfully installed OpenVPN on both server (Windows Server 2019) and pc (Windows 10) using the instructions here: https://community.openvpn.net/openvpn/wiki/Easy_Windows_Guide?__cf_chl_jschl_tk__=pmd_889e3e419b8b865ffd4da6e493bef6df0782273e-1629275604-0-gqNtZGzNAfijcnBszQgi, and I can successfully connect from client to server, however, I cannot connect to any other machine on the Azure subnet upon which the server is sitting.
The server and the other machines I want to connect to are on a 10.0.0.0 subnet, and the VPN is coming up on the 10.8.0.0 network as I would expect from the examples.
I have enabled IP routing on the server as recommended in the OpenVPN FAQ but this has not fixed the issue.
I have also added a 'push "route 10.0.0.0 255.255.255.0"' line to the server config, and I can see from the client log (and the client routing table) that this has been executed, but I am still unable to connect to other machines in the subnet.
I was looking into using Tap instead of Tun, but when I dug into at what was actually being used, it looks as if as if both ends are using the Tap adaptor anyway, even though I have specified 'dev tun' in both the client and the server configs.
I have had bit of a trawl but can't find anything about the Tap adaptor when the Tun adaptor has been configured, so that is a bit of a mystery.
The only other thing that I have read is that it might be necessary to set up a route back to the OpenVPN subnet on the gateway server for 10.0.0.0, but that's not a server I control as it's part of the Azure infrastructure.
What do I have to do to get access to other machines on the 10.0.0.0 subnet? And why is the Tap adaptor being selected despite the config specifying the Tun adaptor ?
I made a number of other changes before I finally got it sorted out - I do not know if they were all necessary but in addition to the above:
I changed 'dev tun' to 'dev tap' in the server and client configs.
I followed the instructions here NAT-hack to add NAT to the server.
And finally, I added 'route 10.0.0.0 255.255.255.0 10.8.0.1' to the
server config file.
I am trying to run this project on Ubuntu 18.04 server. I am running both server and client on this machine. Then from windows 10 with port 9000 I am getting access to client in my chrome browser at http://localhost:8000/#/
The browser loads the project but the problem is I can't log into the website with trusted account and some other data do not get loaded . When I see browser console I see an error message saying:
Failed to load resource: net::ERR_CONNECTION_REFUSED
This is the server setting:
This is the client setting and putty setting to connect to client.
VPN has been used to connect to server via PuTTY.
The error message in browser:
Could anyone shed some light on this issue? Is it related to windows 10 or VPN or some other issues? I followed some steps from here https://www.ionos.com/digitalguide/hosting/technical-matters/err-connection-reset/
By default, the Flask development environment uses 127.0.0.1 (localhost), which restricts access to processes on the same host (except for VMs/containers, which aren't a factor here).
To access Flask from outside of localhost (e.g., from your Windows 10 machine), use the IP address 0.0.0.0. (You can pass it to run(), or via a command line option of the flask command.
However, do note the warnings about (not) using the development environment for production use.
I have a windows server 2016 machine which I have Jenkins running on. I wanted to install SonarQube. So have downloaded v7.1
I have managed to start sonarqube on the machine and can view the webserver at http://localhost:9000
I tried to view the page on a different machine using the IP address and port 9000, but this doesn't connect. Looking in the sonar.properties file I can see
Binding IP address. For servers with more than one IP address, this property specifies which
address will be used for listening on the specified ports.
By default, ports will be used on all IP addresses associated with the server. sonar.web.host=http://xx.xxx.xxxx.xxx
If I use http:// then sonarqube starts, but I can't see sonarqube from any other machine, if I don't use http:// (so just the ip) then it won't start with a bind error.
Has anyone experience of setting this up on windows?
Turns out it was something a lot simpler, the machine is being run on azure and there was no port 9000 endpoint
I have the following setup in my DEV environment which is running on Windows 10 (which should be irrelevant).
Homestead with Virtual box to develop my Laravel applications
on my local OS I have a IBM Domino server running as dev1.mydomain.local
I'm trying to access the REST API on the Domino server from my Laravel installations. At the moment I'm getting 404 errors when trying because the domino server is not available from within the VirtualBox of Homestead.
Here is the network configuration of the homestead virtual box
Both webservers Domino and nginx on the virtual box are running on standard ports
Here is the ifconfig output of the virtual box
How can I make that possible?
UPDATE:
It just came to me that I am able to access the Domino server with LDAP, so perhaps changing the http and https port of the Domino server is already the answer...
I will test that and then get back here...
Changing the Port of the Domino server to 8080 enable me to access the server's REST API
dev1.mydomain.local:8080/api/data/
The connection to the local machine seems to be enable through the VirtualBox's second network adapter and the my call to the REST API got confused with the 2 web servers listening to the same port on localhost(127.0.0.1)
Update
although I was kind of able to connect to the server using the address above, still left me with the problem that authentication wasn't possible. In order to do so (and I have not the slightest idea why), I had to change to the local IP address of my PC to access the REST services
http://192.168.0.155:8080/api/data
If someone could explain that I would be happy :-)
