--- name: "t50" section: "8" platform: "linux" package: "t50" version: "5.8.7b-1" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/t50" --- # t50(8) network packet injector ## NAME T50 - network packet injector ## SYNOPSIS **t50** \[options\] \[--\] *host\[/CIDR\]* ## DESCRIPTION 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: - ``` # t50 -l T50 Experimental Mixed Packet Injector Tool 5.6.15 Originally created by Nelson Brito Previously maintained by Fernando Mercês Maintained by Frederico Lamberti Pissarra [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. ## BUGS As noted before, the "host\[/CIDR\]" argument sometimes is misinterpreted as an option. This bug was introduced when the argument parser was changed to support flexible host "names". Someday I'll correct this (Frederico). ## AUTHORS Nelson Brito ## CONTRIBUTORS Fernando Mercês\ Frederico Lamberti Pissarra ## BUGS and SOURCE CODE AVAILABILITY The latest release of the source code can be downloaded at: T50 GitLab Repository ⟨https://\\:gitlab.com/\\:fredericopissarra/\\:t50⟩\\.
