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: ls find transfer files from the system cat 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/ Peter
