Usage

Overview

Experimental mixed packet injector tool.

This is NOT a DoS tool, but a tool to inject packets using various protocols.

Options

host[/CIDR]

The host address is the target of T50. It can be informed in one of two formats: IP address or URI name. This address can be informed as a range of IPs (by omitting one or mode octects) or using a CIDR separating the IP (full or partial) or URI with "/##", for instance: "192.168/16" or "host.com.local/22". When using a partial IP address T50 will calculate CIDR automatically (8, 16 or 24 bits, if the first, second or third octect [from right to left] are omitted, respectively).

Notice that, sometimes, the "host[/CIDR]" argument is misinterpreted as an option. When this happens, you can use the pseudo option '--' before the host address:

# t50 --flood -- 192.168.1.32/27

Also, to avoid this error you can provide the host address as the first argument.

Notice, also, ONLY IPv4 addresses are allowed. T50 don't provide IPv6 support yet.

--threshold NUM

Number of packets to inject (default 1000).

--flood

Keep injecting packets until user terminates the process (^C). Cannot be used with --threshold.

-B, --bogus-csum

Use a bogus "random " checksum instead of calculating the actual packet checksum.

--turbo

Inject packets faster (creates a child process).

--shuffle

When used with T50 "protocol", it will shuffle the available protocols. Otherwise they will be sent in the same order as listed with --list-protocols option. This option will not work with any other "protocol".

-s, --saddr ADDR

IP header source address (default RANDOM).

-p, --protocol protoname

Select an specific protocol to use (default: TCP. Use --list-protocols to see all protocols available). Use T50 if you want to inject all available protocols. The "protocolname" is case insensitive.

-h, --help

Display all available options and their defaults.

-v, --version

Display t50 version.

-l, --list-protocols

Lists all available protocols T50 can provide.

Examples

See all available protocols:

[INFO]  List of supported protocols (--protocol):
   1 - ICMP (Internet Control Message Protocol)
   2 - IGMPv1 (Internet Group Message Protocol v1)
   3 - IGMPv3 (Internet Group Message Protocol v3)
   4 - TCP  (Transmission Control Protocol)
   5 - EGP  (Exterior Gateway Protocol)
   6 - UDP  (User Datagram Protocol)
   7 - RIPv1  (Routing Internet Protocol v1)
   8 - RIPv2  (Routing Internet Protocol v2)
   9 - DCCP (Datagram Congestion Control Protocol)
   10 - RSVP  (Resource Reservation Protocol)
   11 - IPSEC (Internet Security Protocl (AH/ESP))
   12 - EIGRP (Enhanced Interior Gateway Routing Protocol)
   13 - OSPF  (Open Shortest Path First)

Send 500 packets to a single target:

# t50 192.168.0.100 --threshold 500

Flooding targets from 192.168.0.1 to 192.168.0.254 (notice the partial IP) with TCP packets:

# t50 192.168.0 --flood

Flooding targets from 192.168.0.1 to 192.168.255.254 with all protocols T50 can provide in a random order using "Turbo" mode.

# t50 192.168 --flood -p t50 --shuffle --turbo

Notes

Root privilege is mandatory to run t50.

There are lots of options. Please, use -h or --help to see them and their default values.
