Another option you may use, is to query SNMP information.
The specifics differ slightly from distribution to distribution, but if you're running Ubuntu, for instance, there's a guide on setting up NTP on Ubuntu.
Otherwise, just Google please elaborate further on your answer and supply an explanation to the QA and future readers what does the command you mentioned do and why you recommend such action.
TTL values are different for different Operating Systems. It's still an AIX system, but there's most likely a router in between, decreasing the TTL with one. The nmap utility has a -O option that allows for OS detection: Okay, so it isn't a perfect method either.
So, you can determine the OS based on the TTL value. We ran the nmap command above against an AIX 7.1 system, and it came back as AIX 5.3 instead.
Once I updated Python (and a handful of other dependencies) it started working.
It is not feasible to add options if requests is being called from another package.The idea is pointing the cacert file stored at the system and used by another ssl based applications.In Debian (I'm not sure if same in other distributions) the certificate files (.pem) are stored at file choose, I have browse to the url and check which Certificate Authority (CA) has generated the certificate.especially the fact that you do not seem to use the system ca store first and this is not documented anywhere. I pointed verify to certifi.where() (The code does this by default anyways). Finally I updated my version of python to python 2.7.11.update in situations, where you're using a library and have no control over the ca-bundle location you could also explicitly set the ca-bundle location to be your host-wide ca-bundle: I fought this problem for HOURS. I was on Python 2.7.5 which had some incompatibilities with the way that the certificates are verified.However, CAS requires getting validated via SSL so I have to get past that step first. SSLError: [Errno 1] _ssl.c:503: error:14090086: SSL routines: SSL3_GET_SERVER_CERTIFICATE:certificate verify failed .
