  4. Other ways to disable PC-Speaker

    modprobe -r pcspkr

    Edit /etc/inputrc and add or uncomment the following:
    File: /etc/inputrc

    set bell-style none

    If you're running a suitable kernel (all 2.6 and a few of the more extreme 2.4), you can also disable PC Speaker in the kernel config. It is under Input Devices.

  5. To remember, how to make software bridge for analyzing traffic (using tcpdump, wiresharc, etc.) on Linux:

    ifconfig eth1 -arp promisc 0.0.0.0 up
    ifconfig eth2 -arp promisc 0.0.0.0 up
    brctl addbr br0
    brctl addif br0 eth1
    brctl addif br0 eth2
    ifconfig br0 -arp promisc 0.0.0.0 up

    Configuration of PC should be:
    eth1 - LAN
    eth2 - WAN
    eth0 - Management

    Note: -arp promisc captures all packets ;). brclt is package bridge-utils.
    Remember to shutdown DHCP server, and use filters in tcpdump :)
