1.1 ! root 1: .TH IPCONFIG 8 ! 2: .CT 1 sa_auto ! 3: .SH NAME ! 4: ipconfig, dkipconfig, udpconfig \- set up DARPA Internet protocols ! 5: .SH SYNOPSIS ! 6: .B /usr/ipc/mgrs/ipconfig ! 7: [ ! 8: .B -m ! 9: .I mask ! 10: ] [ ! 11: .B -df ! 12: ] ! 13: .I "ip-device localhost network" ! 14: .BI [ arp-device ] ! 15: .B & ! 16: .br ! 17: .B /usr/ipc/mgrs/dkipconfig ! 18: .I "gatemachine localhost remotehost" ! 19: .B & ! 20: .br ! 21: .B /usr/ipc/mgrs/udpconfig ! 22: .I udp-device ! 23: .B & ! 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. ! 112: .EX ! 113: /usr/ipc/mgrs/ipconfig /dev/il00 fs mh-astro-net /dev/il01 & ! 114: /usr/ipc/mgrs/dkipconfig nj/astro/research fs-dk research-dk127 & ! 115: /usr/ipc/mgrs/udpconfig /dev/ipudp & ! 116: .EE ! 117: .SH FILES ! 118: .F /usr/ipc/log/ipconfig ! 119: .br ! 120: .F /usr/ipc/log/dkipconfig ! 121: .SH "SEE ALSO" ! 122: .IR con (1), ! 123: .IR qns (7), ! 124: .IR route (8), ! 125: .IR tcpmgr (8)
