For God's sake, don't connect this system to the public Internet..... From: dev-bounces@otrs.org [mailto:dev-bounces@otrs.org] On Behalf Of Rafa Quiñonero Figuerola Sent: Wednesday, April 10, 2013 8:34 AM To: Development community of OTRS Subject: Re: [dev] Savin an OTRS DTL file on LINUX In our installation the owner of all the folders and files is the www-data with 644 permissions. Then, in the WinSCP properties, I have 777 permissions available for the WinSCP user. I've never had a problem with the permissions, but yes, maybe the folders doesn't have the right user or group. The files SHOULD be owned by www-data. SCP works because the sshd on Linux runs with privilege escalation capability (it needs it to modify the permissions on ptys when someone logs in) enabled, and adds/drops privileges as needed. File permissions of 777 open the installation to any moron in the universe modifying stuff. It's configured correctly. Don't mess with it. If you need to edit one of these files, use sudo, eg: sudo emacs foo.dtl That will temporarily give you the ability to bypass the file permissions and update the file. See previous note, though.
