I’ve been running into an oddity and i can not find the root cause.
Situation
I have installed OMV on my raspberry pi 4 4GB via:
wget -O - https://raw.githubusercontent.com/OpenMediaVault-Plugin-Developers/installScript/master/install | sudo bash
I also needed to use usrmerge before the installation:
sudo apt install usrmerge
After completion, while being connected via ssh, i can query the omv website and it works fine:
curl localhost
However whenever i try to access it via the browser, it does not. I have ran omv-firstaid as well just to be sure, but that does not change anything.
Network
My Network is connected via ethernet to a repeater (Fritzbox 4040), which in turn connects to the router via ethernet (Frityzbox 7490). Another repeater is also connected.
All are connected as a singular Mesh.
Question
I can connect via port 22 to my pi from anywhere in my house. It works fine and stable due to the mesh. However i can not connect to port 80 for OMV.
I’ve tried port forwarding on my network mesh, but that did not change anything.
I also tried for testing purposes a tunnel via ssh ssh -L 80:localhost:80 pi@raspberrypi.local but that resulted in a:
bind [::1]:80: Permission denied channel_setup_fwd_listener_tcpip: cannot listen to port: 80 Could not request local forwarding
Which makes me think it might be the network on the pi. However I am new to linux networking and therefor would like to ask for your ideas.
I don’t use OMV so take this with a grain of salt, but I would hazard a guess that the web server isn’t listening on port 80.
Try ss -ltn for a list of ports on which the system is listening and ss -nut for a list of active connections. Double-checking firewall rules (commonly ufw) or filter rules (iptables) will be useful for diagnosing connection issues.
