But when user "edward" login to the server by the telnet service, then
he can modify the dot file...
1) No, he can't. Not if the file is owned by root, with no other
permissions.
2) If you allow telnet access, you have more problems to worry about.
Such as anyone with access to your local network, or your Internet
provider's network, being able to capture your login passwords.
For the point 1, user edward he can modify / delete the
dot file....
