\fB-s, --sock, --socket, --vdesock, --unix\fP \fIdirectory\fP
specify the VDE switch directory (default /var/run/vde.ctl).
+The VDE switch directory can be also specified at the end of
+the command, as illustrated by the optional parameter \fIsocketdir\fP
+in the synopsis section, above.
+When '-' is used in place of the VDE switch directory, \fBslirpvde\fP
+works as a plug (see vde_plug(1)).
+The command:
+.br
+.in +5
+.B dpipe vde_plug = ssh remote.machine.org slirpvde -
+.in -5
+.br
+which is the same as:
+.br

+.in -5

+connects the default local switch to a remote slirpvde.

.TP
+\fB-P, --port\fP \fIport\fP

+.TP
\fB-d, --daemon\fP
detach from terminal and run \fBslirpvde\fP in background.
.TP
+\fB-H, --host\fP \fIaddress\fP \fR[ \fB / \fI masklen \fR]
+specify the host address (default 10.0.2.2/24).
+This option automatically defines the network.
+e.g.
+.in +5
+\fB -H 192.168.55.1 \fR
+.in -5
+or:
+.in +5
+\fB --host 10.1.2.3/16 \fR
+.in -5
+The default value for \fImasklen\fR is 24.
+If the host part of the address is zero this option defines only
+the network. The default host addr is addr 2, the default dns proxy is 3.
+e.g.
+.in +5
+\fB -H 10.1.0.0/16 \fR
+.in -5
+defines the network only. The host address is 10.1.0.2 and the DNS proxy
+10.1.0.3.

+\fB-n, --network\fP \fIaddress\fP \fR[ \fB / \fI masklen \fR]
+specify the network address (default 10.0.2.0/24).
+Deprecated, it has been included for back compatibility only. It is
+an alias of \fB-H, --host\fR.
+.TP
+\fB-N, --dns\fP \fIaddress\fP
+Specify the address of the dns server. If this is an address inside
+the slirp network, slirvde acts as a dns proxy on that address.
+The slirpvde dhcp server sends this dns address to the clients.
+By default this is the host number 3 in the slirpvde network. Using the
+default network it is 10.0.2.3.
+Warning: do not use the same address for host and dns.
+.TP
\fB-D, --dhcp\fP
turn on the DHCP server for the network autoconfiguration of
all the units connected to the VDE.
+It is possible to specify the start address assigned by the DHCP server
+as follows:
