<p dir="ltr">One place to start would be with samba. Mint has probably installed at least some part of samba which was originally about windows networking but has been adopted by many Linux distros. Somewhere most likely in /etc/samba will be a samba.conf. If you compare the 2 machines versions and read up in the man and on the web, you may be led to the answer! Some guis and/or file managers do all the clever stuff for you, and it could be as simple as a right click on the the shares you want to offer and relaxing the restrictions. Or there may be firewall issues,</p>
<p dir="ltr">BUT if you're on your own network and just want to share the filesystems, then I suggest you forget all the above and look into SSH and then sshfs. With sshfs you mount the remote filesystem from the directory you choose to the point in the local system that you prepare. From a /mint1 on mint2 and or a /mint2 on mint1 for whole filesystems, down to ~/photos.mint1 or whatever. Note you also choose the user and group you become on the remote system, so have the privileges that user has, also using their password to connect. SSH encrypts for you so you have that extra level of security too. You get the full graphical service in your file manager so can move files by drag and drop or browse to them from applications because the remote machine just appears as part of your local system. It also works painlessly across the internet too, if a little slower. You can script the mounts to happen at startup or logon, but will fail if the remote machine is not online. Better to write the script and run it when you need it and know the other machine is up. Shell history will remember your command line which you can find with an up arrow or control R if you can't be bothered to write a script. Install is from the usual software source for your distro.</p>
<p dir="ltr">Samba is best kept for sharing and printing with windows. Macs use SSH out of the box. I haven't tried sshfs with a Mac. If you turn on X forwarding you can run graphical apps from a remote machine with SSH. Truly a really useful program.</p>
