Description Filipe Rosset 2011-04-17 00:47:35 UTC
SELinux is preventing /usr/bin/python from 'write' accesses on the directory /var/tmp.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that python should be allowed write access on the tmp directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep fail2ban-server /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-04-18 06:19:26 UTC
Any idea why is fail2ban writing to /tmp directory?
