user permissions

i want to give user only some permissions like he can "mount" and run "kppp".
how can i do that.
thanks in advance.

Users can mont partitions specified in /etc/fstab. With other ones there's a problem (and the same with kppp). I guess you need to configure sudo.

oah man configuring sudo is very hard i think.
but isnt there any way to change the execulteable binary,s permission?
and can you tell the line we have to write in/etc/fstab?
thanks a lot for your reply.

in fstab you will normally specify the "user" option. as for the kppp one, well you can set suid bit on the binary (chmod +s /../kppp) but things like that are often checked for by security related programs

chmod 4777 worked on some like "shutdown". but not on a lot of them.so i think now that reading about sudo is necessary.
thanks a lot for your help acid_kewpie and mara .

Well, if you're lazy you can give the program "setuid root". But it's not safe.

no doubt i am lazy.
thats why i am on forum. and as i have come so reply my this question.
with sudo can we bound a user to use some commands like "passwd" with witch user can even change root password.

If its not possible then i think that it is better to do :0: in /etc/passwd in front of user ID.than sudo.
thanks

Well, when you configure sudo, you allow a user to run a certain program as root (or another user). If 'passwd' is not included in the list, the user won't be able to run it as root.
