I set up a VM running openSUSE Tumbleweed and changed the default shell to
zsh. My AVM Fritzbox router regularly probes the VM on port 80 to check for webservices. Because port 80 is closed on the openSUSE system, the request gets blocked.
I also get a dmesg (?) message written to my current
zsh prompt. That didn't seem to be the case with
bash. What could be the reason and how do I stop the messages from appearing (besides opening port 80 of course).
