This is the command tcpclient that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
tcpclient - create an outgoing TCP connection
SYNOPSIS
tcpclient [ -46hHrRdDqQv ] [ -ilocalip ] [ -plocalport ] [ -Ttimeoutconn ] [ -llocalname ]
[ -ttimeoutinfo ] [ -Iinterface ] host port program [ arg ... ]
DESCRIPTION
tcpclient attempts to connect to a TCP server. If it is successful, it runs program with
the given arguments, with descriptor 6 reading from the network and descriptor 7 writing
to the network.
The server's address is given by host and port. host may be 0, referring to the local
machine, or a dotted-decimal IP address, or a host name; if a host has several IP
addresses, tcpclient tries each in turn. port may be a numeric port number or a port
name.
tcpclient sets up several environment variables, as described in tcp-environ(5).
OPTIONS
-ilocalip
Use localip as the IP address for the local side of the connection; quit if localip
is not available.
-plocalport
Use localport as the port number for the local side of the connection; quit if
localport is not available.
-Iinterface
Use interface as the local network interface. This is only defined for IPv6
sockets and needed if you use link-local IPv6 addresses.
-Ttimeoutconn
Give up on the connection attempt after timeoutconn seconds. Default: 60. This
timeout applies to each IP address tried.
-d (Default.) Delay sending data for a fraction of a second whenever the remote host
is responding slowly, to make better use of the network.
-D Never delay sending data; enable TCP_NODELAY. This is appropriate for interactive
connections.
-q Quiet. Do not print any messages.
-Q (Default.) Print error messages.
-v Verbose. Print all available messages.
DATA-GATHERING OPTIONS
-h (Default.) Look up the remote host name for TCPREMOTEHOST.
-H Do not look up the remote host name; unset TCPREMOTEHOST.
-llocalname
Do not look up the local host name; use localname for TCPLOCALHOST.
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host.
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
-ttimeoutinfo
Give up on the TCPREMOTEINFO connection attempt after timeoutinfo seconds. Default:
26.
-4 Fall back to IPv4 sockets. This is necessary for terminally broken systems like
OpenBSD which will not let IPv6 sockets connect to V4-mapped IPv6 addresses.
Please note that this also applies to DNS lookups, so you will have to use an DNS
resolver with an IPv6 address to connect to IPv6 systems. Use DNSCACHEIP to set
the DNS resolver IP dynamically.
-6 Force IPv6 mode in UCSPI environment variables, even for IPv4 connections. This
will set $PROTO to TCP6 and put IPv4-mapped IPv6 addresses in TCPLOCALIP and
TCPREMOTEIP.
