Hello Rein

The WiFiDog has a built-in web server.  By default, that web server  
does not listen to the traditional port 80, but instead on port 2060

The error message below is wifidog complaining that while it was  
setting up that web server, it failed to bind to that port.  The most  
common reason this could happen is if there's something else  
listening on the same port.

Is wifidog already running ? If that's the case, that's where the  
problem is.  The already-running wifidog is already listening on the  

If it's not, you need to find out what's listening on the port and  
resolve that conflict.

If you modified the "GatewayPort" config directive in wifidog.conf to  
something like "80", then "don't do that".  Revert it back to the  
default "2060".  Unless you really know what you're doing you should  
leave that setting untouched.

If it is the default, and you've made sure that no older copy of  
wifidog is currently running, use this command to verify that the  
port is indeed being bound by an application:
netstat -a | grep LISTEN | grep 2060

Then, and this is the hard part, use the process of illimination to  
kill off processes one by one until you finger the one that was  
listening to that port.

There are easier ways to do that last step, but none of the needed  
features are included in the OpenWRT installations I've seen.
