NAME
nemesis-ospf - OSPF Protocol (The Nemesis Project)
SYNOPSIS
nemesis-ospf [-vZ] [optlist]
DESCRIPTION
- 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.
- 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 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.
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 IPoptions-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. IPtype-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.
