Nagios Support Forum

Hello,

I'm trying to perform a new installation of Log Server on one of my servers and during the installation process it appears to be reaching out to try and download an 'argparse' package from I think: pypi.python.org/simple/argparse

My server cannot connect to that location due to an HTTPS connection refused error. I installed Log Server on this same box about 6 months ago and did not have this issue. I'm just curious before I reach out to my Network team for permits, was a new package added to the installation or perhaps an updated download location?

Thank you.

Hello, @rferebee. Are both boxes with Log Server using the same OS? Is it CentOS? What version of LS is installed on the original server?
Can you run the following command on the original server and then on the new server, and show me both outputs?

pip install 123 --verbose | grep Looking

Thanks

The original servers are running CentOS 6 and the new ones are running CentOS 7 (I was told this wouldn't be an issue).

The original servers are currently on LS 2.0.6. I was trying to install 2.0.7 on the new ones, but I also tried 2.0.6 which also failed.

Original output:

[root@nagioslscc1 ~]# pip install 123 --verbose | grep Looking

@rferebee, I looked at install scripts of LS 2.0.6 and LS 2.0.7 and they look pretty similar. Both have the line to install argparse via pip. Although, two servers may have two different versions of python and pip but I don't see how that would explain this. Are you sure that argparse is not installed on the original LS? Can you run the following command and show me the output?

pip show argparse

[root@nagioslscc1 ~]# pip show argparse

@rferebee, This means that the argparse package is installed on the original log server as well. And pip on both servers is trying to connect to:

https://pypi.python.org/simple/

So somehow the original server was able to connect to the pypi.python.org repo, or someone installed this package manually offline.

We can lock this thread. We ended up just temporarily allowing all traffic to the server we were installing Log Server on and it was able to get the packages it needed.

Thank you.

@rferebee, Thanks for the update! I will be closing this thread as resolved.
