I am having trouble mounting with cifs, but mounting the exact same command with smbfs works fine. The share is on another samba server and is set to full public guest access.
# mount -t cifs //servername/sharename /mnt/temp -o password=""
mount error 13 = Permission denied Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) ==> /var/log/messages
