Write Privileges and Mounting Devices- HOW???

[Johnny3]

Hello Folks,

Can someone explain the different levels of security in Knoppix/Linux?

Exactly how do you obtain write privileges for the different devices?

Has anyone ever installed CDrecord successfully?

Is there a listing of error codes and ways to correct them?

Can someone explain the different levels of security in Knoppix/Linux?
This question is very vague. Every file (which is everything) has read/write/exe permission flags for the owner/group/world. These can all be changed by people with the correct permission or the superuser (root). There are hundreds of security features in linux. A lot of is based on this principle.

Knoppix (the version booted from the CD) is not very secure compared to carefully configured linux systems. Although, it is very secure, even compared to a carefully setup version of windows. For example, there is no password for the super user by default in Knoppix. This is ok, because it is fine for what knoppix is meant to do.


Exactly how do you obtain write privileges for the different devices?

Each device in linux is listed in /dev/. Each of these is a file jsut like everything else in linux/unix. They have the same permission scheme as described above. You can use the chmod command to change the permissions.


Has anyone ever installed CDrecord successfully?

cdrecord is insatlled and working by default on Knoppix.
