       tsctp — SCTP Test Tool

SYNOPSIS

       tsctp  [-a  indication]  [-A  type]  [-D]  [-f  fragmentation_point]  [-l  buffersize] [-L local_address]
             [-n number_of_messages] [-p port] [-R rcvbufsize] [-S sndbufsize] [-t timetolive] [-T runtime] [-u]
             [-U udp_port] [-v] [-V] [-4] [-6] [remote_address]

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.
