SVN-Update: Error in creating dhcpd.conf

[Tom Elliott]

@Wayne-Workman said:

ip addr show $interface | awk -F’[ /]’ ‘/([0-9][0-9]?[0-9]?.){3}([0-9][0-9]?[0-9]?){1}/ {print $6}’

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]

Now it’s better - I still get the Info

 * Setting up storage..........................................OK
 * Setting up and starting DHCP Server......................... !!! No router address found !!!
 !!! No dns address found !!!
OK
 * Setting up and starting TFTP and PXE Servers................OK

but the script continues and everything seems to be ok.

[Wayne Workman]

@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?

[Oleg]

@Wayne-Workman
yes in both files are the addresses set correctly

[Wayne Workman]

@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.

[Oleg]

@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:

## End of FOG Settings

And this is the dhcpd.conf:

...
next-server 192.168.94.111;
# Specify subnet of ether device you do NOT want service.
# For systems with two or more ethernet devices.
# subnet 136.165.0.0 netmask 255.255.0.0 {}
subnet 192.168.94.0 netmask 255.255.255.0{
    option subnet-mask 255.255.255.0;
    range dynamic-bootp 192.168.94.60 192.168.94.99;
    default-lease-time 21600;
    max-lease-time 43200;
    option routers 192.168.94.1;
    option domain-name-servers 192.168.94.1;
...

Confirmed, found, here is the fix:

Sorry @Tom-Elliott for just posting this here but I don’t think this is worth a pull request…

[Tom Elliott]

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

[Sebastian Roth]

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

[Tom Elliott]

@Sebastian-Roth Added to the code and pushed.

[Wayne Workman]

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

[Oleg]

Perfect now! Installer and configs are all correct. From my side the problem is solved. Thanks!
