+## Remote networking
+
+If you can create a pipe between two hosts (using SSH, for example), you can use VDE (Virtual Distributed Ethernet) to connect the two hosts over a virtual network.
+
+You need the following programs on both hosts:
+
+* dpipe and vde_plug (on Debian, use the vdeplug package)
+* vde-switch (on Debian, use the vde-switch package)
+
+Run as root on both hosts:
+
+```
+vde_switch -t tap0
+```
+
+This command creates a virtual switch connected to tap0.
+
+Use the dpipe command to connect two instances of the vde_plug command running as root on both hosts.
+
+```
+$ dpipe sudo vde_plug = ssh root@remote vde_plug
+```
+
+Then bring the tap0 interface up and configure IP addresses on both hosts.
+
+```
+# ip link set tap0 up
+# ip addr add $IP/$NETMASK dev tap0
+```
