SVN-Update: Error in creating dhcpd.conf

Wayne Workman

And when I start the installer everything seems ok because both entries are listed correctly:

If it’s fine now, don’t worry about it. Just update periodically (I update usually daily).

Oleg

sorry but I completly removed FOG and try to install it again but it doesn’t work.
I get this error:

* Setting up and starting DHCP Server.........................../lib/common/functions.sh: line 186: addr:192: syntax error in expression (error token is ":192")
../lib/common/functions.sh: line 288: let: octet4+=: syntax error: operand expected (error token is "+=")
 !!! No router address found !!!
 !!! No dns address found !!!
Failed!

Thanks

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

@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:

And this is the dhcpd.conf:

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!
