Permissions
Directory and file permissions
Standard Unix file permissions are supported on the DCC, ACLs are not supported.
By default when users create a new directory the default permissions are "755" (non-group-writable). To automatically create new directories or files that are group writable, run the command:
umask 002;echo "umask 002" >> ~/.bashrc
This will change the default permissions to "775" (group-writable).
