+.SH NAME
+dnsdist \- A DNS and DoS aware, scriptable loadbalancer
+.SH SYNOPSIS
+.sp
+dnsdist [<option>...] [address]...
+.SH DESCRIPTION
+.sp
+\fBdnsdist\fP receives DNS queries and relays them to one or more
+downstream servers. It subsequently sends back responses to the original
+requestor.
+.sp
+\fBdnsdist\fP operates over TCP and UDP, and strives to deliver very high
+performance over both.
+.sp
+Currently, queries are sent to the downstream server with the least
+outstanding queries. This effectively implies load balancing, making
+sure that slower servers get less queries.
+.sp
+If a reply has not come in after a few seconds, it is removed from the
+queue, but in the short term, timeouts do cause a server to get less
+traffic.
+.sp
+IPv4 and IPv6 operation can be mixed and matched, in other words,
+queries coming in over IPv6 could be forwarded to IPv4 and vice versa.
+.sp
+\fBdnsdist\fP is scriptable in Lua, see the dnsdist documentation for more
+information on this.
+.SH SCOPE
+.sp
+\fBdnsdist\fP does not \(aqthink\(aq about DNS queries, it restricts itself to
+measuring response times and error codes and routing questions
+accordingly. It comes with a very high performance packet\-cache.
+.sp
+The goal for dnsdist is to remain simple. If more powerful loadbalancing
+is required, dedicated hardware or software is recommended. Linux
+Virtual Server for example is often mentioned.
+.SH OPTIONS
+.INDENT 0.0
+.TP
+.BI \-a \ <netmask>\fR,\fB \ \-\-acl \ <netmask>
+Add \fInetmask\fP to the ACL.
+.TP
+.BI \-C \ <file>\fR,\fB \ \-\-config \ <file>
+Load configuration from \fIfile\fP\&.
+.TP
+.B  \-\-check\-config
+Test the configuration file (which may be set with \fB\-\-config\fP or \fB\-C\fP)
+for errors. dnsdist will show the errors and exit with a non\-zero
+exit\-code when errors are found.
+.TP
+.BI \-c \ <address>\fR,\fB \ \-\-client \ <address>
+Operate as a client, connect to dnsdist. This will read the dnsdist
+configuration for the \fBcontrolSocket\fP statement and connect to it.
+When \fIaddress\fP (with an optional port number) is set, dnsdist will connect
+to that instead.
+.TP
+.BI \-k \ <key>\fR,\fB \ \-\-setkey \ <key>
+When operating as a client(\fB\-c\fP, \fB\-\-client\fP), use \fIkey\fP as
+shared secret to connect to dnsdist. This should be the same key
+that is used on the server (set with \fBsetKey()\fP). Note that this
+will leak the key into your shell\(aqs history and into the systems
+running process list. Only available when dnsdist is compiled with
+libsodium support.
+.TP
+.BI \-e\fP,\fB  \-\-execute \ <command>
+Connect to dnsdist and execute \fIcommand\fP\&.
+.TP
+.B  \-h\fP,\fB  \-\-help
+Display a helpful message and exit.
+.TP
+.BI \-l\fP,\fB  \-\-local \ <address>
+Bind to \fIaddress\fP, Supply as many addresses (using multiple
+\fB\-\-local\fP statements) to listen on as required. Specify IPv4 as
+0.0.0.0:53 and IPv6 as [::]:53.
+.TP
+.B  \-\-supervised
+Run in foreground, but do not spawn a console. Use this switch to
+run dnsdist inside a supervisor (use with e.g. systemd and
+daemontools).
+.TP
+.B  \-\-disable\-syslog
+Disable logging to syslog. Use this when running inside a supervisor
+that handles logging (like systemd).
+.TP
+.BI \-u\fP,\fB  \-\-uid \ <uid>
+Change the process user to \fIuid\fP after binding sockets. \fIuid\fP can be
+a name or number.
+.TP
+.BI \-g\fP,\fB  \-\-gid \ <gid>
+Change the process group to \fIgid\fP after binding sockets. \fIgid\fP Can
+be a name or number.
+.TP
+.B  \-V\fP,\fB  \-\-version
+Show the dnsdist version and exit.
+.TP
+.B  \-v\fP,\fB  \-\-verbose
+Be verbose.
+.UNINDENT
+.sp
+\fBaddress\fP are any number of downstream DNS servers, in the same syntax as used
+with \fB\-\-local\fP\&. If the port is not specified, 53 is used.
+.SH BUGS
+.sp
+Right now, the TCP support has some rather arbitrary limits.
