i need a second NIC to connect to a second network with an separate IP. I tryed to use sudo ifconfig eth0:1 192.168.1.20 netmask 255.255.255.0 up and restart the network, but there is no second NIC.
Then i would try the network manager, but they crashed immediately after start.
Unless you have a server/workstation m/b with 2 network chip sets like mine, I do not think it is possible to connec to 2 separate networks with a single network device.
