I do things the easiest way that gets the job done.  Someone asked me recently about mounting a shared windows drive in Linux from bash.  They stated they normally mount it through dolphin using:


That works until you need to copy files via rsync or some other bash method.  The solution is actually very simple:

mount -t cifs //ip_address/SHARED_DRIVE /mnt/directory -o user=username,password=user_password_on_windows_share,uid=500,gid=500

Just be sure you replace uid=500 with the users id in linux and gid=500 with the users group id in linux in order to be able to write files/directories with the proper permissions.  Of course the mount directory, /mnt/directory, also must exist.

If you get an error about “mount error(12): Cannot Allocate Memory

the fix is:

Edit the windows registry

Set “HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache” to “1″.
Set “HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size” to “3″.
Restart the “server” service.

Sometimes you will run into an issue where you have multiple computers that mysteriously stop syncing with dropbox. What I have found is it is almost always caused by 1 of 2 things……file permissions, conflicts. I have 8 devices syncing to my dropbox, and every single one of them are linux except for one. It seems as though anytime I use my sole Windows computer to add something to dropbox….the others mess up. I suspect an issue with linux file permissions and windows ntfs drives.

Anyways, this script will fix the problems. Make sure you adjust the path if your linux install does not have dropbox at ~/Dropbox.
