CasperCheck - zip file corrupt

[EmmaV3]

Hello,

Bit of background; I re-designed our JSS on a separate server to our existing JSS and created loads of new functionality for it. One of the things I implemented was that wonderful CasperCheck auto-reenrollment policy which worked like a charm.

However we wanted to keep the same JSS name so we retired the old server and re-named the new one (jss.companyname.com)

One of the last stages of the switch would be re-implementing the CasperCheck policy along with the associated CasperCheck.pkg (containing caspercheck.sh, and LaunchDaemon to call the script) and the new QuickAdd.pkg for the re-named server.

Originally I had housed the Quickadd.pkg.zip on the same web server as the JSS, so it was just a case of replacing that file with the new one.

Now however, when I run the caspercheck.sh script I get the following output:

2015-10-08 10:36:57 ======== Starting CasperCheck ========
2015-10-08 10:36:57 Checking for active network connection.

2015-10-08 10:38:57 Downloaded zip file appears to be corrupted. Exiting CasperCheck.
2015-10-08 10:38:57 ======== CasperCheck Finished ========

And calling the script in terminal results in this:

[/tmp/quickadd.zip] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of /tmp/quickadd.zip or /tmp/quickadd.zip.zip, and cannot find /tmp/quickadd.zip.ZIP, period.

I've verified the files with 'file' in terminal:
QuickAdd.pkg.zip: Zip archive data, at least v1.0 to extract

Compressing on 10.9.5 then tried 10.10.5 also Windows.

Has anybody come across this or have any thoughts?

Thanks!

It appears to be something to do with the web server (possibily as a result of changing the name) as I uploaded the QuickAdd.pkg.zip to another webserver and:

2015-10-08 15:38:17 Downloading Casper agent installer from server.
2015-10-08 15:38:17 Downloaded zip file appears to be a valid zip archive. Proceeding.

Ah :(

Now you know why I added that check. :-)

Smart man!

Do you know what may be causing that then? Out of curiosity I verified the integrity of the downloaded zip file from the problematic web server and I get this:

quickadd.pkg.zip: Zip archive data, at least v1.0 to extract
zip -T quickadd.pkg.zip test of quickadd.pkg.zip OK

I did a 'diff' on the .zip files downloaded from either web server (identical QuickAdds) and the diff said the binary on both .zips differ but once they're extracted it says the files are identical.

I know very little about the inner workings of web servers!

Thanks!
