Do you have any device installed on USB on your server? If not maybe it
would be a good thing to prevent the service from starting at boot.
And one more thing Shorewall is not the firewall. He is a front-end of
the real firewall - iptables in wich it inserts rules.
Yes, I do have a canon mp700 photosmart, copy, scan and color connected
to the usb-port. The device is used by ms-windows boxes in the net
through samba. Works perfect in this enviroment. But the access to the
printer is not disturbed by the error message "kernel: usb-uhci.c:
interrupt " Only when eth1 goes down, and as mentioned, eth0 slows down,
it is not accessible.
The printer is installed in /etc/printcap, and service used is lpd.
Would it help to install in cups instead, disable lpd and enable cupsd?
