.SH NAME
ipsec_pf_key \- lists PF_KEY sockets registered with KLIPS
.SH SYNOPSIS
.B cat
.B /proc/net/pf_key
.SH DESCRIPTION
.I /proc/net/pf_key
is a read-only file which lists the presently open PF_KEY sockets on the
local system and their parameters.
.PP
Each line lists one PF_KEY socket.
A table entry consists of:
.IP + 3
sock pointer (sock)
.IP +
PID of the socket owner (pid)
.IP +
flag to indicate if the socket is dead (d)
.IP +
socket wait queue (sleep)
.IP +
socket pointer (socket)
.IP +
next socket in chain (next)
.IP +
previous socket in chain (prev)
.IP +
last socket error (e)
.IP +
pointer to destruct routine (destruct)
.IP +
is this a reused socket (r)
.IP +
has this socket been zapped (z)
.IP +
socket family to which this socket belongs (fa)
.IP +
local port number (n)
.IP +
protocol version number (p)
.IP +
Receive queue bytes committed (r)
.IP +
Transmit queue bytes committed (w)
.IP +
option memory allocations (o)
.IP +
size of send buffer in bytes (sndbf)
.IP +
timestamp in seconds (stamp)
.IP +
socket flags (Flags)
.IP +
socket type (Type)
.IP +
connection state (St)

.LP
shows that there is one pf_key socket set up that starts at
.BR c3b8c140 ,
whose owning process has PID
.BR 3553 ,
the socket is not dead, its wait queue is at
.BR c0599818 ,
whose owning socket is at
.BR c05997fc ,
with no other sockets in the chain, no errors, no destructor, it is a
reused socket which has not been zapped, from protocol family
.BR 15
(PF_KEY), local port number
.BR 0 ,
protocol socket version
.BR 2 ,
no memory allocated to transmit, receive or option queues, a send buffer
of almost
.BR 64kB ,
a timestamp of
.BR 0.103232 ,
no flags set, type
.BR 3 ,
in state
.BR 1 .
