I found a solution how to resolve host-names from DHCP. Here is the solution:
Add those two lines:
1) in section
init_header, after line
echo " 'policy'" >> $CONFIGFILE
echo " , 'hints'" >> $CONFIGFILE
2) in section
load_uci_config_common, after line
set_param_func "cache.clear" ""
set_param_func "hints.config" "'/tmp/hosts/dhcp'"
restart the KNOT service:
If you edit
/etc/config/dhcp and add anything you want, it will be resolved as well.
