An optional length for the buffer. Defaults to 512 bytes.

gets

This reads a buffer delimited by the eol from the channel.

errno

A class method to return the SSH error number.

$buffer

The buffer to be written.

puts($buffer)

This writes a buffer that is terminated with eol to the channel. Returns the number of bytes written.

$buffer

The buffer to send over the socket.

disconnect
