Reopen issue 464 - Githubissues

hbouma1 commented 6 years ago

After testing of NCPA build from https://assets.nagios.com/downloads/ncpa/ncpa-2.1.5.sle11.x86_64.rpm the issue still exists. Please re-open the issue as it is not fixed.

Did you install zlib on the system? I tested it on a basic install of SLES 11, but we do install zlib for the build so it may be a problem if it's not installed on the system.

hbouma1 commented 6 years ago

Yes, zlib is installed and an available module in Python.

We are seeing this on a base install of SLES 11 SP4 as well as our entire environment of SLES servers.

The python version installed on the system doesn't actually matter. NCPA comes with it's own frozen version of Python 2.7.x (using cx_freeze) so modules in your version of python is not the issue. The NCPA binary is having problems extracting the zip file inside /usr/local/ncpa that includes the files that it requires in order to actually run the agent - which means somehow it is not able to use the zlib library on the system. You could try manually setting the library path to see why it is not finding zlib.

Please let me know if there are steps in the installation process that I am missing. I just duplicated the issue on a fresh install of SLES 11 SP4 64bit by doing the following:

· Go to https://download.suse.com/index.jsp

· I selected SUSE Linux Enterprise Server, SUSE Linux Enterprise Server 11 SP4, All Dates.

· Downloaded SUSE Linux Enterprise Server 11 SP4 for AMD64/Intel64https://download.suse.com/Download?buildid=tqRrEpjl5SY~ (SLES-11-SP4-DVD-x86_64-GM-DVD1.iso).

· Install to VMWare Workstation using defaults

· First boot, I logged in, started a terminal and entered the following:

So it looks like my export was removed from the init script, can you try installing the new version https://assets.nagios.com/downloads/ncpa/ncpa-2.1.5.sle11.x86_64.rpm

hbouma1 commented 6 years ago

That worked.

Thank you!

jomann09 commented 6 years ago

Awesome!
