SVN-Update: Error in creating dhcpd.conf

Oleg · Mar 9, 2016, 2:14 PM

Hello guys,

while updating the snv 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”) Failed!

in the dhcpd.conf the installer stops to create the netmask ip address and it looks like this:
subnet netmask 255.255.255.0{
option subnet-mask 255.255.255.0;
…

Also, what version you’re on will be helpful to future readers and for historical accuracy.

Look and see what you have set for dns and router in your /opt/fog/.fogsettings file.
Within the quotes, there should just be an IP and not text or white space or semi colons, although there is a semicolon after the ending quote so don’t be confused by that.

Oleg · Mar 10, 2016, 4:50 AM

I didn’t realise that the Verision of FOG in the /opt/fog/.fogsettings ist still 6476. The current version I’m using is 6651.
Maybe beacause of the old options in .fogsettings FOG is not configuring correctly.
Can someone show me how the current .fogsettings file has to look like?

Here is my current:

@Oleg The installer will write a new version of the fogsettings file when finishing successfully. Just corrrect the “routeraddress” and “dnsaddress” lines and you should be fine I’d say:

routeraddress="192.168.94.1";
...
dnsaddress="192.168.94.1";

Oleg · Mar 10, 2016, 5:17 AM

@Sebastian-Roth thanks - I tried that but it is still showing me the error.
Setting up and starting DHCP Server…/lib/common/functions.sh: line 186: addr:192: syntax error in expression (error token is “:192”)
Failed!
I changed the lines and there are now only the IP-addresses

Sebastian Roth · Mar 10, 2016, 4:05 PM

@Oleg said:

Which lines (in which file) do you mean?

Wayne Workman · Mar 11, 2016, 3:40 AM

@Oleg if you can update to the latest via SVN, the installer should now auto-correct these older settings types for the router and dns addresses in the .fogsettings file.

Oleg · Mar 11, 2016, 10:46 AM

@Sebastian-Roth I mean the lines you told me in .fogsettings :

routeraddress="192.168.94.1";
...
dnsaddress="192.168.94.1";

@Wayne-Workman
The installer give me the same error and say

 !!! No router address found !!!
 !!! No dns address found !!!

My .fogsettings file is this now:

## Created by the FOG Installer

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

...
 * DHCP router Address: 192.168.94.1
 * DHCP DNS Address: 192.168.94.1

Thanks

I think you may need to reset your trunk folder.

The version appears to be an indicator to me. Considering the warnings you saw above weren’t even introduced until sometime yesterday (well into the 6600 version numbers).

Oleg · Mar 11, 2016, 12:42 PM

How can I reset the trunk folder?
Thanks

Tom Elliott · Mar 11, 2016, 12:48 PM

@Oleg It’s easiest to just remove the current and recheck out. It sounds like other files have been being edited.

You could try running:

svn revert -R * from the root of the trunk folder, but I still think starting fresh would be best.

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

Oleg · Mar 11, 2016, 5:10 PM

@Wayne-Workman

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")

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

@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 · Mar 15, 2016, 11:23 PM

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

Wayne Workman · Mar 15, 2016, 11:35 PM

@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.
