NAME

suck, blow —

transfer data over a TCP connection

SYNOPSIS

suck [-v] [-p port] [remote-ip]

blow [-v] [-p port] [remote-ip]

DESCRIPTION

Suck and blow are simple programs used to transfer data over a TCP connection. Blow is the originator of the data, which is read from standard input, while suck is the recipient of the data, which is written to standard output.

Either program may originate the TCP connection which is used for the transfer; whichever program is supplied with the remote-ip argument will be the originator. The other program is expected to have already been started, with no remote-ip argument, causing it to await a connection from the peer.

These programs are often useful in conjunction with archiving programs such as tar(1).

The options are as follows:

-v: Increased verbosity.
-p: Specify an alternate TCP port to use. The default port is 6060.

EXAMPLES

To transfer the directory hierarchy mystuff from machine A to machine B, first on machine B:

[machineB] $ suck | tar xvf -

and then on machine A:

[machineA] $ tar cvf - mystuff | blow machineB

If machine B was behind a firewall, you could do this instead:

[machineA] $ tar cvf - mystuff | blow

and then on machine B:

[machineB] $ suck machineA | tar xvf -
