How to Set Dual IP addresses with a single Nic in Linux.1. Set the first IP Address:[Root @ linux root] # cd/etc/sysconfig/network-Scripts[Root @ Linux Network-Scripts] # vi ifcfg-eth0Device = eth0Bootproto = staticBroadcast = 192.168.80.255 // * broadcast address *//Ipaddr = 192.168.80.189 // * The first IP Address *//Netmask = 255.255.255.0 // * network mask *//Network = 192.168.80.0 // * network segment

to ensure that the ARP response destined to the peer is not blocked by the switch.Necessary:The condition 1:ethtool supports obtaining the rate of each slave;Condition 2: The underlying driver supports setting the hardware address of a device so that there is always a slave (curr_active_slave) using the hardware address of bond, while ensuring that slave in each bond has a unique hardware address. If the Curr_active_slave fault, its hardware address will be newly elected to the Curr_active_slav

Solution to a Single Windows XP dual-nic NAT problem -- Windows XP, dual network card, one connected to the internet, the other connected to the Intranet, do not work! Finally, I found out the crux of the problem... a concept: the number of hops. The number of hops indicates the routing overhead, usually the number of hops to the IP target location. Everything

port, an intranet network, requires 2 gateways, the first gateway is configured under the interface, that is, vi/etc/sysconfig/network-scripts/ifcfg-ethxThe 2nd gateway is the write static route, edit the static route configuration file Vi/etc/sysconfig/route-ethx,x is the number of the network port, so please note that this must correspond, otherwise the configuration will have a problem6. If the device has 2 network cards, the customer mistakenly switch off a network card, then ask to open th

network, this block has a great problem, Temporarily did not study it), does not change the inside network card, only in the WiFi to tamper: Directly writes the IP4 IP and the mask on the WiFi network card, the other all does not set, then the WiFi connection on the router (outside the network route), but it is not on the net, all outside the network request, will be automatically sent to the intranet network card. You can see from the CMD route print output that it has only one route. However,

The organization accesses two networks at the same time. One is broadband access, the Intranet address is 192.168.1.x, the other is an internal private network, and the Intranet address is 192.168.3.x. The private network needs to access a 10.0.0.x address. The two networks are connected to one vswitch at the same time. Because the office computer only has one network card installed and only one network cable is connected, re-wiring is not possible, so when you want to connect to the broadband n
