@Substring thanks for the solution. I did something similar, which was to add an entry to the hosts file to make "recalbox.com" point to the IP of www.recalbox.com. To be able to do that, I had to remount the file system as writable. The commands were:
ssh root@192.168.X.X
and then type the default password for the root user (described in the wiki)mount -o remount,rw /
echo "163.172.165.227 recalbox.com" >> /etc/hosts
