:SELinux is preventing /usr/sbin/sshd from 'write' accesses on the chr_file null.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that sshd should be allowed write access on the null 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 sshd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
