| Thanks in advance......
|
| However, I still would like to ask that how can I let a nomral user to
| execute the "traceroute" command ???
|
| In fact, I have already change the access right of the "traceroute" to
| 777, but I still can't make it.....!!
|
| Any advice please !!!!!!
|
| Winnie.....
you did say "any advice"...
you'll save yourself some grief down the road if you avoid using 777 to
address permission problems.
by making this world-writable, you've allowed anyone who can login to
your system (legit or otherwise) the ability to replace traceroute with
a file of his or her choosing. if you do this to a text file, you allow
it to be edited as well as replaced. they can't delete it, but this is
worse.
imagine the following snippet...
c! d $HOME
rm -r *
as a shell script named traceroute. now imagine your users running it,
at your suggestion yet.
ouch.
if you want users to execute something, just set the execute bits (755,
or even 555).
