Here is one way to mount a folder on another computer (using Linux eg Mint or Ubuntu):
First, you need to know the IP addresses of the computers .. however, remember that unless they are static, these numbers may change from time to time .. on each computer, from a terminal window, you can type:
to list the 'inet addr' for that computer. For example on my laptop it shows inet addr:192.168.2.22 in the wlan0 section ..
also, in Linux Mint cifs-utils is installed by default, but if not, it can be installed or verified from the terminal as well with the command:
sudo apt-get install cifs-utils
(if it was already installed, you just get a nice message to that effect).
now, moving on .. on the computer you want access from, set up the sharing options.
In Ubuntu with Nautilus, you can just right-click on the folder and select 'Sharing Options'. With Mint and the Thunar file manager that option is missing, but you can accomplish these tasks from the command line .. something like this:
net usershare delete ShareDocs
net usershare add ShareDocs /home/user/Documents ”” Everyone:F guest_ok=y
net usershare info --long
(which removes a share, shares your folder at /home/user/Documents with share name of your choice, in this case, 'ShareDocs' to Everyone with Full access, and lists the results)
next, you will want to create a folder (mount point) for the share on the other computer, the one you want to share to:
sudo mkdir /media/shared
(current Ubuntu distributions like to use the /media folder for this sort of thing instead of /mnt .. which is standard used by older/other Linux distros .. but it's fine to use either) and finally, use a command like this to mount the share:
sudo mount.cifs //192.168.2.22/ShareDocs /media/shared -o user=USERNAME
Remember to replace USERNAME with the username for the Samba server that you need to log in as. You'll be prompted for your password. You can specify your password on the command-line too (with -o password=PASSWORD) but it will appear in cleartext in the Terminal and will go into your command history, so you probably don't want to do that. So, if all went well so far, the folder on the other computer linked to the share name ShareDocs will now be linked to this computer in the /media/shared folder .. you'll find the newly shared directory listed in your files manager files (sweet!) but only until you reboot your computer. To automate the connection, you have to insert the mount command into your fstab file .. or repeat the steps above each time you want to access the files ..
