Once I need to mount a Windows share on my Ubuntu Server.
By default the folder was mounted as readonly but I fixed that by supplying dmask=777,fmask
Here is the command I used.
mount -t smbfs -o username=guest,password=,dmask=777,fmask=777 //192.168.0.10/myshare /mnt/existing_folder/
If you have any ideas or if I can add something and/or improve this article do leave a comment.
