NAME¶packetsender - Network utility for sending and receiving TCP, UDP, SSL packets
packetsender [options] address port data
DESCRIPTION¶Packet Sender is a utility that sends and receives TCP, UDP and SSL (encrypted TCP) packets on the ports of your choosing. It supports IPv4 and IPv6 and provides a GUI for final users. However, is also possible use Packet Sender in text mode via command line.
- Can act as client/server to send and receive network traffic.
- A payload can be created in ASCII or hex.
- Command line mode is available for automation and scripting.
- Packet Sender cloud is a disposable resource to be used to publicly display and distribute packets (via an URL) for collaboration, tutorials, end users, etc. Packet Sender may import public packet sets with public URL.
- Control network-based devices in ways beyond their original apps.
- Test automation (using command line tool and/or hotkeys).
- Test network APIs (using the built-in TCP, UDP, SSL clients).
- Malware analysis (using the built-in UDP, TCP, SSL servers).
- Troubleshoot secure connections (using SSL).
- Test network connectivity/firewalls (by having 2 Packet Senders talk to each other).
- Stress-test a device (using intense network generator tool).
- Tech support (by sending customers a portable Packet Sender with pre-defined settings and packets).
- Share/Save/Collaborate using the Packet Sender Cloud service.
- -h, --help
- Displays this help.
- -v, --version
- Displays version information.
- -q, --quiet
- Quiet mode. Only output received data.
- -x, --hex
- Parse data-to-send as hex (default).
- -a, --ascii
- Parse data-to-send as mixed-ascii (like the GUI).
- -A, --ASCII
- Parse data-to-send as pure ascii (no \xx translation).
- -w, --wait <ms>
- Wait up to <milliseconds> for a response after sending. Zero means do not wait (Default). It is compulsory if a reply from a server, as an HTTP server, is needed. In this case, -w 500 is a good start value.
- -f, --file <path>
- Send contents of specified path. Max 10 MiB for UDP, 100 MiB for TCP/SSL.
- -b, --bind <port>
- Bind port. Default is 0 (dynamic).
- -6, --ipv6
- Force IPv6. Same as -B "::". Default is IP:Any.
- -4, --ipv4
- Force IPv4. Same as -B "0.0.0.0". Default is IP:Any.
- -B, --bindip <IP>
- Bind custom IP. Default is IP:Any.
- -t, --tcp
- Send TCP (default).
- -s, --ssl
- Send SSL and ignore errors.
- -S, --SSL
- Send SSL and stop for errors.
- -u, --udp
- Send UDP.
- -n, --name <name>
- Send previously saved packet named <name>. Other options overrides saved packet parameters.
- Destination address. Optional for saved packet.
- Destination port. Optional for saved packet.
- Data to send. Optional for saved packet.
EXAMPLES¶The following command line will send a TCP packet, with a mixed-ascii as payload, to example.com, port 22. The command will wait 500 ms for a reply.
$ packetsender -taw 500 example.com 22 "Hello\nWorld"Similar to last command, but the TCP packet will be sent to port 21. An anonymous authentication will be used.
$ packetsender -taw 500 example.com 21 "USER anonymous\r\nPASS firstname.lastname@example.org\r\n"The command below uses SSL and will ignore SSL errors. The command will wait 500 ms for a reply.
$ packetsender -saw 500 expired.packetsender.com 443 "GET / HTTP/1.0\r\n\r\n"Other good example how to access a homepage:
$ packetsender -w 500 -a example.com 80 "GET / HTTP/1.1\r\nHost: example.com\r\n\r\n"Packet Sender command line also can bind to custom ports to force IPv4/6 modes or multiple NIC, as shown below:
$ packetsender -taw 3000 fe80::c07b:d517:e339:5a08 5005 "Hello\r" $ packetsender -taw 3000 192.168.0.201 5005 "Hello\r" $ packetsender -B 192.168.0.200 -taw 3000 192.168.0.201 5005 "Hello\r" $ packetsender -B fe80::a437:399a:3091:266a%ethernet_32769 -taw 3000 fe80::c07b:d517:e339:5a08 5005 "Hello\r" $ packetsender -B fe80::a437:399a:3091:266a -taw 3000 fe80::c07b:d517:e339:5a08 5005 "Hello\r"
