:SELinux is preventing /usr/bin/python2.7 from read, write access on the chr_file ptmx.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that python2.7 should be allowed read write access on the ptmx chr_file 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 hpfax /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
