Correct me if I am wrong, but you have a permissions problem. If user1 can
read and access user2 files you simply need to change the file permissions
on user1 files. Also look at the umask assigned to each user for default
file creation.
File permissions are independent of access type (ssh / telnet / console)
SSH simply provides access to the shell, It does not control your permission
levels.
I think its also possible to "Jail" a user to his/her directory tree
preveting them from going higher in the filesystem.
Did I mis-understand the question / problem ?
