nemesis-ospf [-vZ] [optlist]

The Nemesis Project is designed to be a command line-based, portable human IP stack for UNIX-like and Windows systems. The suite is broken down by protocol, and should allow for useful scripting of injected packets from simple shell scripts.

-p OSPF Protocol (-pH, -pL, -pR)
	Hello (-pH), Database Description (-pD), Link State Request (-pL), Link State Update (-pU), Router Links Advertisement (-pR), Network Links Advertisement (-pN), IP Summary Links Advertisement (-pM), AS External Link Advertisement (-pA),

-N Neighbor Router Address
	Neighbor Router Address.
-i Dead Router Interval
	Dead Router Interval.
-l OSPF Interval
	OSPF Interval.

-z MAX DGRAM Length
	OSPF Maximum Datagram Length
-x Exchange Type
	OSPF DBD Exchange Type

-x Num LSAs to bcast
	Number of Link State Advertisements to broadcast

-L Router ID Router ID for Link State Advertisement packets.

-G LSA Age
	Link State Advertisement Age.

-u LSA_RTR Number Router Links Advertisement Number

-y LSA_RTR Router Type
	Router Links Advertisement Router Type
-k LSA_RTR Router Data
	Router Links Advertisement Router Data

-f LSA_AS_EXT Forward Address Autonomous System Forward Address

-g LSA_AS_EXT Tag
	Autonomous System Tag

-m OSPF Metric OSPF Metric

-s OSPF Sequence Number
	OSPF Sequence Number
-r OSPF Advertising Router Address
	OSPF Advertising Router Address
-n OSPF Netmask
	OSPF Netmask Address
-O OSPF Options
	OSPF Options
-R OSPF Router ID
	OSPF Router Identifier
-A OSPF Area ID
	OSPF Area Identifier
-P Payload File
	Filename to read for packet payload.
-v verbose-mode
	Display the injected packet in human readable form. Use twice to see a hexdump of the injected package with printable ASCII characters on the right. Use three times for a hexdump without decoded ASCII.

-D destination-IP-address	Specify the destination-IP-address within the IP header.
-F fragmentation-options (-F[D],[M],[R],[offset])	Specify the fragmentation options: -FD (don’t fragment) -FM (more fragments) -FR (reserved flag) -F <offset> within the IP header. IP fragmentation options can be specified individually or combined into a single argument to the -F command line switch by separating the options with commas (eg. ’-FD,M’) or spaces (eg. ’-FM 223’). The IP fragmentation offset is a 13-bit field with valid values from 0 to 8189. Don’t fragment (DF), more fragments (MF) and the reserved flag (RESERVED or RB) are 1-bit fields. NOTE: Under normal conditions, the reserved flag is unset.
-I IP-ID	Specify the IP-ID within the IP header.
-O IP-options-file	This will cause nemesis-ospf to use the specified IP-options-file as the options when building the IP header for the injected packet. IP options can be up to 40 bytes in length. The IP options file must be created manually based upon the desired options. IP options can also be read from stdin by specifying ’-O -’ instead of an IP-options-file.
-S source-IP-address	Specify the source-IP-address within the IP header. IP-type-of-service (TOS) within the IP header. Valid type of service values: 2 (Minimize monetary cost) 4 (Maximize reliability) 8 (Maximize throughput) 24 (Minimize delay) NOTE: Under normal conditions, only one type of service is set within a packet. To specify multiple types, specify the sum of the desired values as the type of service.
-T IP-TTL	Specify the IP-time-to-live (TTL) within the IP header.

-d Ethernet-device	Specify the name (for UNIX-like systems) or the number (for Windows systems) of the Ethernet-device to use (eg. fxp0, eth0, hme0, 1).
-H source-MAC-address	Specify the source-MAC-address (XX:XX:XX:XX:XX:XX).
-M destination-MAC-address	Specify the destintion-MAC-address (XX:XX:XX:XX:XX:XX).
-Z list-network-interfaces	Lists the available network interfaces by number for use in link-layer injection. NOTE: This feature is only relevant to Windows systems.

Nemesis-ospf returns 0 on a successful exit, 1 if it exits on an error.
