I wrote a python test plugin /usr/lib64/nagios/plugins/check_test.py . The file content is below which tries to read a file from another server and does some checks as shown below
#!/usr/bin/python
import re
import sys
import datetime
import paramiko
import select
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect('10.11.12.13')
sftp_client = client.open_sftp()
remote_file = sftp_client.open('/data/var/test.log')
remote_file.prefetch()
try:
//Some checks and sets errorFound as 0 or 1
finally:
remote_file.close()
if (errorFound):
exit(1)
else:
exit(0)
I am able to run this /usr/lib64/nagios/plugins/check_test.py directly from my linux CentOs without any problem. But when I load this script as a service on icinga . I see a warning against the service and below error
Error Below:
22/Sep/2021 Traceback (most recent call last): File “/usr/lib64/nagios/plugins/check_test.py”, line 16, in client.connect(‘10.34.187.17’) File “/usr/lib/python2.7/site-packages/paramiko/client.py”, line 305, in connect retry_on_signal(lambda: sock.connect(addr)) File “/usr/lib/python2.7/site-packages/paramiko/util.py”, line 269, in retry_on_signal return function() File “/usr/lib/python2.7/site-packages/paramiko/client.py”, line 305, in retry_on_signal(lambda: sock.connect(addr)) File “/usr/lib64/python2.7/socket.py”, line 224, in meth return getattr(self._sock,name)(*args) socket.error: [Errno 13] Permission denied
I have set full permission for below files listed in error above but no luck
/usr/lib64/python2.7/socket.py
/usr/lib/python2.7/site-packages/paramiko/client.py
Anything I am missing here?

I just execute the py script manually after I logged in with my username. I did not use icinga user
Also I executed
sudo setenforce 0 and now the the sestatus current mod is permissive. I get a new errr now on the service in icinga as shown below
