The WebIF allows adding host names with space in their name. Right after the WebIf successfully saved this host to its internal custom file and obviously successfully rebuilded the final hosts file, DNS stopped working. What’s even worse, I’ve modified this faulty entry in WebIF again and removed the space character. To my surprise, DNS still did not work! I had to use a SSH session and execute the following commands for DNS working properly again. /usr/local/bin/rebuildhosts /usr/local/bin/unboundctrl restart Michael PS: unfortunately there is no component in Bugzilla where this ticket fits in, no DNS, no unbound or similar, so I've chosen component network.
