It is not working with ARM cpu, Oracle

[boka003]

Hello there,

I have installed Beszel on my Oracle ARM VM, and it is working fine at port 8090.
But if i try to add my ARM VM's for monitoring, it will not work.
I have some Ryzen VM's and they are working fine.

Is the hub also hosted on this machine?

Please check the logs page in PocketBase (/_/#/logs) for information about the connection error and let me know what it says.

[boka003]

It is the same if i use the main server (with a hub) or an additional server without hub.

It is working fine on https://fivenines.io/

I can provide you login as this is test server, can ARM CPU be a problem?

[henrygd]

Sure, you can send a login to hank at henrygd.me

ARM CPU should not be a problem. I have an arm64 Oracle VM myself and have not had issues monitoring it, though I did need to unblock the port in the Oracle cloud interface.

[boka003]

Thanks i have send it from [email protected]

Hmm i have unblocked ports: https://i.postimg.cc/xC4mVyMP/image-1.png

And it is working fine on fivenines.io for example, but self hosted solution is better :)

[henrygd]

Thanks, took a quick look and it definitely appears to be a network issue.

From the monitoring VM, we can connect to the working system with telnet:

telnet <ip> 45876

This does not work for any of the Oracle VMs. However it does work using port 80:

telnet <ip> 80

This is a strong indication that port 45876 is still being blocked by a firewall.

Try running this directly on one of the Oracle machines:

telnet localhost 45876

If you can connect, the agent is working properly. It's a problem with external connections.

My Oracle VM had iptables active and I had to unblock the port in that as well, so I recommend trying that.

Save your current rules:

sudo iptables-save > ~/ipt.fw

Unblock port 45876:

sudo iptables -I INPUT -p tcp --dport 45876 -j ACCEPT

Then try telnet again from the monitoring VM. Hopefully your agent can now connect. If so, use iptables-persistent to save the rules.

Let me know if this doesn't solve it.
