man nemesis-ospf (Commandes) - OSPF Protocol (The Nemesis Project)
NAME
nemesis-ospf - OSPF Protocol (The Nemesis Project)
SYNOPSIS
nemesis-ospf [-vZ] [optlist]
DESCRIPTION
The Nemesis Project is designed to be a commandline-based, portable human IP stack for UNIX/Linux. The suite is broken down by protocol, and should allow for useful scripting of injected packet streams from simple shell scripts.
OSPF Packet Types
- -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),
OSPF HELLO options
- -N Neighbor Router Address
- Neighbor Router Address.
- -i Dead Router Interval
- Dead Router Interval.
- -l OSPF Interval
- OSPF Interval.
OSPF Database Description (DBD) options
- -z MAX DGRAM Length
- OSPF Maximum Datagram Length
- -x Exchange Type
- OSPF DBD Exchange Type
OSPF Link State Update (LSU) options
- -x Num LSAs to bcast
- Number of Link State Advertisements to broadcast
OSPF Link State Advertisement (LSA) related options
-L Router ID Router ID for Link State Advertisement packets.
- -G LSA Age
- Link State Advertisement Age.
OSPF Router Links Advertisement (LSA_RTR) options
-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
OSPF Autonomous System External Link Advertisement (LSA_AS_EXT) options
-f LSA_AS_EXT Forward Address Autonomous System Forward Address
- -g LSA_AS_EXT Tag
- Autonomous System Tag
OSPF options
-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 human readable output of currently injected packet.
IP OPTIONS
- -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 injectect 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.
DATA LINK OPTIONS
- -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.
DIAGNOSTICS
Nemesis-ospf returns 0 on a successful exit, 1 if it exits on an error.
