NAME

tsctp — SCTP Test Tool

SYNOPSIS

DESCRIPTION

tsctp is an SCTP test tool. It can be used to make basic tests with the SCTP protocol. For the tool to work, the kernel needs to support SCTP, i.e. sockets with protocol IPPROTO_SCTP.

Linux: echo sctp >/etc/modules-load.d/sctp.conf

Then, reboot to load the module. Note: Ensure that the SCTP module is not blacklisted (e.g. /etc/modprobe.d/sctp-blacklist.conf in Fedora Linux)!

FreeBSD: echo 'sctp_load="YES"' >>/boot/loader.conf

Then, reboot to load the module.

ARGUMENTS

The following arguments may be provided:

-a indication

Set adaptation layer indication.

-A type

Set chunk type to authenticate .

-D

Turns Nagle off.

-f fragmentation_point

Set fragmentation point.

-l buffersize

Set size of send/receive buffer. For sending messages, this means the message size!

-L local_address

Set local address.

-n number_of_messages

Set number of messages to be sent (0 means infinite)/received.

-p port

Set port number.

-R rcvbufsize

Set socket recv buffer.

-S sndbufsize

Set socket send buffer.

-t timetolive

Set time to live for messages.

-T runtime

Set time to send messages.

-u

Set use of unordered messages.

-U udp_port

Use UDP encapsulation with given port.

-v

Enable verbose output.

-V

Enable very verbose output.

-4

Use IPv4 only.

-6

Use IPv6 only.

remote_address

If a remote address is given, the client mode is used. Then, tsctp connects the socket to the given remote address. Otherwise, without given remote address, the server mode is used. Then, tsctp listens for incoming connections.

EXAMPLES

tsctp -l :: -l 0.0.0.0 -p 1234

Server mode: bind to all IPv4 and IPv6 addresses, listen on port 1234.

tsctp -l :: -l 0.0.0.0 -p 1234 -n 10 -l 1000 127.0.0.1

Client mode: bind to all IPv4 and IPv6 addresses, connect to localhost (127.0.0.1) on port 1234, send 10 messages of 1000 bytes each.

tsctp -l :: -l 0.0.0.0 -p 1234 -n 0 -T 10 -l 4096 127.0.0.1

Client mode: bind to all IPv4 and IPv6 addresses, connect to localhost (127.0.0.1) on port 1234, send unlimited number of messages of 4096 bytes each, stop after 10 s.
