dev

The dev pseudo-file contains network device status information. This gives the number of
received and sent packets, the number of errors and collisions, and other basic statistics. These are used
by the ifconfig(8) program to report device status. The format is

rarp
</TD><TD>
This file uses the same format as the ARP file and contains the current reverse mapping
database used to provide rarp(8) reverse address lookup services. If
rarp is not configured into the kernel, this file will not be present.
</TD></TR><TR><TD>
raw
</TD><TD>
Holds a dump of the RAW socket table. Much of the information is not of use apart
from debugging. The sl value is the kernel hash slot for the socket; the
local_address is the local address and protocol number pair.
St is the internal status of the socket. The
tx_queue and rx_queue are the outgoing and incoming data queue in terms of kernel memory usage. The
tr, tm->when, and rexmits fields are not used by RAW. The
uid field holds the creator euid of the socket.
</TD></TR><TR><TD>
route
</TD><TD>
No information but looks similar to
route(8).

snmp
</TD><TD>
This file holds the ASCII data needed for the IP, ICMP, TCP, and UDP management
information bases for an snmp agent. As of writing, the TCP
mib is incomplete. It should be completed by 1.2.0.
</TD></TR><TR><TD>
tcp
</TD><TD>
Holds a dump of the TCP socket table. Much of the information is not of use apart
from debugging. The sl value is the kernel hash slot for the socket; the
local_address is the local address and port number pair. The
remote_address is the remote address and port number pair
(if connected). St is the internal status of the socket. The
tx_queue and rx_queue are the outgoing and incoming data queue in terms of kernel memory usage. The
tr, tm->when, and rexmits fields hold internal information of the kernel socket state and are only useful for debugging. The
uid field holds the creator euid of the socket.

udp

Holds a dump of the UDP socket table. Much of the information is not of use apart
from debugging. The sl value is the kernel hash slot for the socket; the
local_address is the local address and port number pair. The
remote_address is the remote address and port number pair
(if connected). St is the internal status of the socket. The

Num is the kernel table slot number,
RefCount is the number of users of the socket,
Protocol is currently always 0, and Flags represents the internal kernel flags holding the status of the
socket. Type is currently always 1 (UNIX domain datagram sockets are not yet supported in the kernel).
St is the internal state of the socket and Path is the bound path (if any) of the socket.
