But then the ethernet-card is not set to promiscous mode... As root it does not work. And it does not root when startet with sudo wireshark . Damn! Any other ideas ? (I checked it with the option as mentioned above and with the xhost settings.) Keep hacking! mcc -- gentoo-user@gentoo.org mailing list

[...] Is there any way to allow root to use the X display when a user has opened the session and su'ed to root ? On my system I can simply su and all is fine. But if a am logged in from remote via SSH I get the same problem when I su. ssh -X [EMAIL PROTECTED] should work, but I guess you just need to emerge sux and use it instead of su. However, this works only if your user has X access and then becomes root - when opening a root shell in a text console, it does not work. In this case, your first solution seems to work fine for me.
