How to create an SSH/telnet user with read-only permissions ?
I want to allow a telnet/SSH user to peek into my system but have no write permissions.
In other words he should be able to e.g. perform:
transfer files from the system
Ok, I could add an user with useradd command.
But then: How can I apply the non-write (=read-only) permission to him ?
And additionally: Assuem the same situation as above but the user should get now
write permissions to the folder /user/home/myuser123/
