Does it relate with fact that cups execs smbtool?
NAME
smbspool - send a print file to an SMB printer
Does it need to read pid file?
This is due to the smb backend being used, and this is a symlink to /usr/bin/smbspool, yes. I don't know why/whether smbspool needs to read /var/run/nmbd. Looks like reading the nmbd PID is part of libsmb, so this is expected. gasdim, could you execute $ semanage permissive -a cupsd_t re-test it and see if you get more AVC msgs $ ausearch -m avc -ts recent $ semanage permissive -d cupsd_t (In reply to comment #4) > gasdim, > could you execute $ semanage permissive -a cupsd_t I checked this. No message. All fine. $ ausearch -m avc -ts recent I checked this. The reply no matches. $ semanage permissive -d cupsd_t I checked this. No message. All fine Thanks for the reply!
