24: .SH DESCRIPTION
25: .I Ipconfig
26: activates the DARPA Internet protocol on a communications device,
27: with Internet address
28: .I localhost
29: for the host
30: and network address
31: .I network
32: for the device.
33: .PP
34: If
35: .I arp-device
36: is specified,
37: the ARP address resolution protocol
38: is started on that device.
39: Option
40: .B -d
41: causes
42: .I ipconfig
43: to print ARP requests on the standard output
44: as they are received.
45: .PP
46: Option
47: .B -m
48: declares a subnet mask
49: for the network reached through
50: .IR ip-device .
51: .I Mask
52: may be a four-piece IP address like
53: .L 255.255.255.0
54: or a 32-bit hexadecimal number like
55: .LR ffffff00 .
56: .PP
57: Option
58: .B -f
59: is a special workaround for networks with obsolete hosts.
60: It causes
61: .I ipconfig
62: to answer illegal ARP requests for the subnet's broadcast address
63: with an illegal Ethernet address,
64: to prevent broadcast storms.
65: .PP
66: .I Dkipconfig
67: places a network call to
68: .I gatemachine
69: and activates the IP protocol on the connection,
70: so that the remote machine becomes a gateway for the caller's IP traffic.
71: .I Localhost
72: becomes the calling machine's Internet address
73: through this IP interface;
74: .I remotehost
75: is the Internet address
76: to which local IP packets should be sent
77: to reach the gateway.
78: .PP
79: .I Ipconfig
80: and
81: .I dkipconfig
82: record unusual events and errors in
83: log files
84: .F /usr/ipc/log/ipconfig
85: and
86: .FR /usr/ipc/log/dkipconfig .
87: .PP
88: .I Udpconfig
89: activates the UDP datagram protocol
90: on the named
91: .IR udp-device ,
92: usually
93: .FR /dev/ipudp .
94: Only one
95: .I udpconfig
96: is needed for the entire collection of IP networks.
97: .PP
98: These programs are usually run once from
99: .IR rc (8).
100: .SH EXAMPLES
101: The following calls start IP
102: on system
103: .B fs
104: on the first Interlan Ethernet controller,
105: with ARP active;
106: arrange for machine
107: .B nj/astro/research
108: to pass IP packets to
109: .BR fs ;
110: and activate
111: UDP.
