tsctp(1) General Commands Manual tsctp(1) NAME 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 Fe- dora 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's Algorithm 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. EXIT STATUS The tsctp tool exits with 0 on success, and >0 in case of an error. 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 -n 10 -l 1000 -p 1234 127.0.0.1 Client mode: bind to all IPv4 and IPv6 addresses, connect to local- host (127.0.0.1) on port 1234, send 10 messages of 1000 bytes each. tsctp -L :: -L 0.0.0.0 -n 0 -T 10 -l 4096 -p 1234 127.0.0.1 Client mode: bind to all IPv4 and IPv6 addresses, connect to local- host (127.0.0.1) on port 1234, send unlimited number of messages of 4096 bytes each, stop after 10 s.
