when you have a prompt you can check the pemissions with: # ls -l /
you'll then see something like:
drwxr-xr-x ....... /tmp
there are three sets of permissions, first the owner of the file/directory then the group then everyone else. if everyone can write it will read:
drwxrwxrwx .../tmp
you can change permissions with chmod using either letters for the permissions or a numeric code
7 means read, write and execute, 777 means everyone can rwx
doing # chmod 777 /tmp should do the trick
