      I’m looking at this, looks like the serverip variable inside of lib/common/functions.sh is never getting set for the configureDHCP function.

      I’ve made a few adjustments to show this, along with the contents before/after for the router and dns stuff.

      What’s most concerning is the addr: part in the output…

      serverip=addr:192.168.94.111

      configureDHCP() {
    dots "Setting up and starting DHCP Server"
    case $bldhcp in
        1)
            [[ -f $dhcpconfig ]] && cp -f $dhcpconfig ${dhcpconfig}.fogbackup


echo "--------------------------------------"
echo interface=$interface
echo serverip=$serverip
echo submask=$submask
echo "---------------------------"

            serverip=$(ip addr show $interface | awk -F'[ /]' '/([0-9][0-9]?[0-9]?\.){3}([0-9][0-9]?[0-9]?){1}/ {print $6}')
            [[ -z $serverip ]] && serverip=$(/sbin/ifconfig $interface | awk '/inet[:]?.*(cast)/ {print $2}')
            [[ -z $serverip ]] && serverip=$(/sbin/ip -4 addr show $interface | awk -F'[ /]+' '/global/ {print $3}')
            [[ -z $submask ]] && submask=$(cidr2mask $(getCidr $interface))

echo "------------------------"
echo serverip=$serverip
echo "-------------------"


            network=$(mask2network $serverip $submask)
            [[ -z $startrange ]] && startrange=$(addToAddress $network 10)
            [[ -z $endrange ]] && endrange=$(subtract1fromAddress $(echo $(interface2broadcast $interface)))
            [[ -f $dhcpconfig ]] && dhcptouse=$dhcpconfig

        Found a few issues with how the controls were in place and added elements to make corrections as needed. This should be fixed now.

            @Oleg Can you please check to see if there is a Router/DNS address set inside of /etc/dhcp/dhcpd.conf ? Also, what are the router and DNS values inside of /opt/fog/.fogsettings now?

                @And if you re-run the installer, you should no longer get those messages !!! No dns address found !!!

                If you do not see those messages anymore, then this issue is resolved.

                  @Wayne-Workman I really don’t want to dissapoint you 😇
                  I’ve updated now to the svn 6755 and still get the ! ! ! No router address found ! ! ! and ! ! ! No dns address found ! ! !
                  How I said before - the setup is complete and everything seems to work. I only get these two “warnings”

                  Here is my .fogsettings:

                      @Sebastian-Roth That’s fine, but it doesn’t appear to have all the data.

                      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

                        Yeah, just noticed…updated my post. Essentially it’s just some brackets missing to make the logic work like it should [[ ...]] && ... || ( ... && ...)

                            @Oleg Can you please update and try again since there has been another fix to this? Ideally, you should no longer get the warnings.
