Starting wireshark with "su -c ..." and then clicking at Help->Website yields
into this :

tfoerste@n22 ~ $ su -c /home/tfoerste/devel/wireshark/wireshark
Password:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Unable to connect to X server
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(firefox-bin:8848): Gtk-WARNING **: cannot open display: :0.0
firefox-bin exited with non-zero status (1)


until I give an "xhost +" as normal user. BTW an "xhost +localhost" or sth
similar also doesn't help. I'm wondering about that b/c I'm able to start xterm
as root and as a normal user with " su -c xterm" w/o to use xhost command
before.
