.SH DESCRIPTION
.B Netstat
prints information about the Linux networking subsystem.
.SS "(no option)"
By default,
prints information about the Linux networking subsystem. The type of
information printed is controlled by the first argument, as follows:
.SS (none)
By default,
.B
netstat
prints the status of network connections by listing the open
sockets. If you don't specify any address families, then the active
sockets of all configured address families will be printed. With
.BR \-\-extend " (" \-e )
you get some additional information (userid). Use it twice to add
more information (inode number). With the
.BR \-\-verbose " (" \-v )
option, you can make netstat complain about known address families which are
not supported by the kernel. The
.BR \-\-timers " (" \-o )
option prints some additional information on networking timers. Enabling the
.BR \-\-program " (" \-p )
will show you the process PID and name of the program that has the socket
open.
.BR \-\-listening " (" \-L )
makes
.B
netstat
show only the sockets which are only listening, which are omitted by default.
With
.BR \-\-all " (" \-a ),
you get both the listening and the non-listening sockets. The address
family
.B inet
includes raw, udp and tcp protocol sockets.
displays a list of open sockets. If you don't specify any
address families, then the active sockets of all configured address
families will be printed.
.SS "\-\-route , \-r"
With the
.BR \-\-route " (" \-r )
option, you get the kernel routing tables in the same format as
.B "route -e"
use.
.B "netstat --route --extend"
uses the output format of
.BR route .
Please see
.BR route (8)
for details.
Display the kernel routing tables.
.SS "\-\-groups , \-g"
With the
.BR \-\-groups " (" \-g )
option, IGMP multicast group membership information for IPv4 and IPv6 is
printed.
Display multicast group membership information for IPv4 and IPv6.
.SS "\-\-interface=\fIiface \fR, \fB\-i"
If you use the
.BR \-\-interfaces " (" -\i )
option, a table of all (or the specified
.IR iface )
networking interfaces will be printed. The output uses the
.B "ifconfig -e"
format, and is described in
.BR ifconfig (8).
.B "netstat --interface --extend"
will print a table or a single interface entry just like
.B ifconfig
does. With the
.BR \-\-all " (" \-a )
option, you can include interfaces which are not configured (i.e. don't have
the
.BR U = UP
flag set).
Display a table of all network interfaces, or the specified
.IR iface ) .
.SS "\-\-masquerade , \-M"
This generates a list of masqueraded sessions. With the
.BR \-\-extend " (" \-e )
option, you can include some more information about sequence numbering and
deltas, caused by data rewrites on FTP sessions (PORT
command). Masquerade support is used to hide hosts with unofficial network
addresses from the outside world, as described in
.BR ipfw "(4), " ipfwadm "(8), and " ipfw (8).
Display a list of masqueraded connections.
.SS "\-\-statistics , \-s"
.B netstat
prints summary statistics for each protocol.
.SS "\-\-netlink , \-N"
Recent kernels have a kernel/user communication support called netlink. You
can get messages about creation or deletion of interfaces or routes from
.I /dev/route
(36,0).
.PP
Display summary statistics for each protocol.
.SH OPTIONS
.SS "\-\-verbose , \-v"
Tell the user what is going on by being verbose. Especially print some
useful information about unconfigured address families.
.SS "\-\-numeric , \-n"
shows numerical addresses instead of trying to determine symbolic host, port
Show numerical addresses instead of trying to determine symbolic host, port
or user names.
.SS "\-\-protocol=\fIfamily \fR, \fB\-A"
Specifies the address families (perhaps better described as low level
protocols) for which connections are to be shown.
