i have been using linux for a year now..and have come to be pretty proficient with it...however there are still a few things i have no idea about...and thats where this thread comes in.
coudl someone please educat me on the significance of uid and gid and what does someone mean when they say that the app shud be installed suid root.
thanks a lot.
Originally posted by jtshaw Check out sudo instead of using su. Sudo allows you to give extra permissions on a temporary basis to users.
The problem with suid shutdown commands is if you have users who log in remotely you certainly don't want them to be able to reboot you.
Not a problem for me: This is a home PC, and it's not normally hooked up to my network. It's just an inconvenience to have to su all the time. Perhaps now I can even have a launcher give the shutdown command....
uid is User id
and gid is group id
gid could be of two types one is primary and other secondary group.
that mean if
user ( rob gid is 555) then (spike gid can also be 555) that mean spike is under primary group of rob.
