How to Mount a Linux directory from a different PC to your local Linux PC?
You need to be a bit more specific. You can use NFS.
Depending on what distro you're using, you simply edit the /etc/exports file on the remote machine to export the directories you want, then start your NFS daemon.
Then on the local PC, you mount it using the following command:
mount -t nfs {remote_pc_address}:/remote/dir /some/local/dirUse the man utility for more information:
man exports (Examples of configuring directories for export are on the bottom of this manual page.)
