Does eSupport license roundrobin DNS twin server install?

[AndyW]

We have setup our eSupport domain across twin servers, with identical files, using the same central database. The dns is set to round-robin.

Apparently, the second server in giving an error indicative of a license issue,

Warning: Cannot modify header information - headers already sent by (output started at /home/xxxxx/public_html/helpdesk/config/config.php:123) in /home/support/public_html/helpdesk/includes/functions.php on line 1612

Does eSupport license allows for a twin server, round-robin dns installation ?
My support is expired and i don't want to renew just to be told this is not possible.

TIA for anyone who can shed some light on this.

Did you delete the setup directory? I know this happens when you don't delete it...

Hi Criagbrass,

I just copied an installed working file set, to the new server and ran it from there on the existing database.

Verified no setup directory and the only change is in the config.php

define("SWIFTCUSTOMPATH", '/home/support/public_html/helpdesk');

Please try deleting all files in the /cache/ directory inside Kayako. At this point, also clear your browser's cache and cookies and then try to see if the error still appears.

All you need to do is open up config/config.php and remove any blank lines before the <?php and any blank lines after ?>.

Clearing directories/support tickets etc are unnecessary.

Hi Chris,

Although the steps you covered in your post do solve a similar issue, I do not believe it is related to the problem Andy is having.

Because the licensing is based on the domain, if the second server has a different domain to the primary (which is registered) then it will output an "Invalid licence..." error as well as the "Already sent..." error.

Then he would have pasted that as well.

My assumption is based on the fact that straight after putting up eSupport (and probably editing the config file with notepad or another dodgy text editor) he received the error which made him think that it was a licensing error with having eSupport on a second server.

With the round robin DNS, the servers would be sharing the same domain (ie, in Apache for example the ServerName would be set the same) so they both answer requests for it.

You have hit it on the head. Yes there is a single eSupport domain being services by a 3server setup (2web and 1mysql). Both web use the same domain, same php configs and filesets but have different hostnames.

Thanks a ton Chris Boulton!

Yes, this has fixed it, seems the tar/gzip/ftp somehow added two lines after ?>
