When using DHCP as client your computer leaves traces of its mac address, hostname and even some uuid at hosting network.

It is possible to leave lower mark.


emerge net-analyzer/macchanger app-arch/sharutils


File: /etc/conf.d/net
my_name=`cat /dev/urandom | head --bytes 9 | uuencode -m - | head -n 2 | tail -n 1`

preup() {
        [ -f /var/lib/dhcpcd/dhcpcd.duid ] && rm /var/lib/dhcpcd/dhcpcd.duid
        return 0

rc_net_eth0_need="firewall"     # optional, if you have firewall
dhcp_eth0="release nontp nonis nosendhost"
dhcpcd_eth0="-h ${my_name} -I ${my_name}"
