+# 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 `vde_switch -t tap0` as root on both hosts.
+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.
+
+```console
+$ dpipe sudo vde_plug = ssh root@remote vde_plug
+```
+
+Then bring the `tap0` interface up and configure IP addresses on both hosts.
+
+```console
+# ip link set tap0 up
+# ip addr add $IP/$NETMASK dev tap0
+```
