running gdb as root without running eclipse as root [message #187264]

Hi,

I am developing a small program that uses the libpcap library. For the
program to work I need to start it as root. By using setuid I managed to
have the program working when using the Run perspective but how do I get
the same with the debugger??
I tried adding an alias: gdb sudo gdb but when started with eclipse I am
still the owner of the process... If I try to start gdb outside of
Eclipse, no problem, owner is root.

Any idea?
Thanks for any help
Anne

Hi Anne,

you could try to wrap

sudo gdb $*

into a script and then specify the script as debugger instead of the "gdb"
default.

Silly question... did you set executable permission on the script?

Not a silly question at all... I tried so many different things in the
last few days, that I did not check that!
So yes with executable permission it does work!!

Thanks a lot for your help!

I need help on this issue as well.

I get "Error creating session
sudo: sorry, you must have a tty to run sudo"

Is there a way I can work this around?

You might need one of the graphical versions of sudo. If you are using
kde try using kdesu , and if you are using gnome try gksu instead of the
sudo command.

Hello Joe,

Thanks for tip.

Now I understand what the problem is. Although I am using fedora/GNOME
and fedora does not seem to have gksu.

I will further investigate in the fedora forums.

Here's another solution.
(I think) eclipse must be running as root as well to manipulate gdb

login as root
create a file called /etc/security/console.apps/eclipsesu

enter the information below

---------
USER=root
PROGRAM=/usr/bin/eclipse
SESSION=true
---------

create a file called /etc/pam.d/eclipsesu

enter the following informa below
----------
#%PAM-1.0
auth include config-util
account include config-util
session include config-util
----------
do
#ln -s /usr/bin/eclipse /usr/bin/eclipsesu

from gnome or kde run /usr/bin/eclipsesu

This will popup the root passwd screen. Then you are good to go.

Hasan Ceylan

Hi;

I'm having the same problem and tried the above solutions,
(setting debugger to sudo gdb, or to batch file running as gdb as root user)
but I keep getting an error message in Eclipse "Cannot run program" "unknown reason",
when trying to debug.

Please advise me what I'm doing wrong.
