1ISIC -- IP Stack Integrity Checker 2 3Description: 4ISIC is a suite of utilities to exercise the stability of an IP Stack and its 5component stacks (TCP, UDP, ICMP et. al.) It generates piles of pseudo random 6packets of the target protocol. The packets be given tendancies to conform to. 7Ie 50% of the packets generated can have IP Options. 25% of the packets can 8be IP fragments... But the percentages are arbitrary and most of the packet 9fields have a configurable tendancy. 10 11The packets are then sent against the target machine to either penetrate its 12firewall rules or find bugs in the IP stack. 13 14ISIC also contains a utility generate raw ether frames to examine hardware 15implementations. 16 17Other Uses: 18Other novel uses people have found for ISIC include IDS testing, stack 19fingerprinting, breaking sniffers and barraging the IRC kiddie. 20 21 22Warning: 23ISIC may break shit, melt your network, knock out your 24firewall, or singe the fur off your cat 25 26 27usage: isic [-v] [-D] -s <source ip> -d <destination ip> 28 [-p <pkts to generate>] [-k <skip packets>] [-x <send packet X times>] 29 [-r <random seed>] [-m <max kB/s to generate>] 30 Percentage Opts: [-F frags] [-V <Bad IP Version>] 31 [-I <Random IP Header length>] 32notes: 33 [-D] causes packet info to be printed out -- DEBUGGING 34 35 ex: -s a.b.c.d -d a.b.c.d -F100 36 100% of the packets will be ^^^^ fragments 37 ex: -s a.b.c.d -d a.b.c.d -p 100 -r 103334 38 ex: -s rand -d rand -r 23342 39 ^^^^ causes random source addr 40 ex: -s rand -d rand -k 10000 -p 10001 -r 666 41 Will only send the 10001 packet with random seed 666 42 this is especially useful if you suspect that packet is 43 causing a problem with the target stack. 44
