Make a Copy of a File on Remote SSH Server

Demonstrates how to make a copy of a file on a remote SSH server by running the "cp" command. This works if your server is Linux or Unix-based. For Windows-based servers, use the DOS "copy" command.

#  Important: It is helpful to send the contents of the
#  ssh.LastErrorText property when requesting support.

#  Any string automatically begins a fully-functional 30-day trial.
success = ssh.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print ssh.lastErrorText() + "\n"
    exit

#  Connect to an SSH server:

#  Hostname may be an IP address or hostname:
hostname = "192.168.1.117"
port = 22

success = ssh.Connect(hostname,port)
if (success != true)
    print ssh.lastErrorText() + "\n"
    exit

#  Wait a max of 5 seconds when reading responses..
ssh.put_IdleTimeoutMs(5000)

#  Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword")
if (success != true)
    print ssh.lastErrorText() + "\n"

#  Open a session channel.  (It is possible to have multiple
#  session channels open simultaneously.)

#  In this example, we'll copy wine.html to wine2.html
#  The "cp" command has no output (i.e. nothing is written to
#  the standard output) so we'll include an "echo FINISHED"
#  so we can programmatically retrieve the output and close
#  the channel.  Closing the channel immediately after sending
#  the command is not good because w/ some SSH servers
#  it introduces a race condition where the command may not
#  be executed if the server thinks the client has disconnected.
success = ssh.SendReqExec(channelNum,"cp wine.html wine2.html && echo FINISHED")
if (success != true)
    print ssh.lastErrorText() + "\n"

#  Read the channel until we receive the FINISHED string.
success = ssh.ChannelReceiveUntilMatch(channelNum,"FINISHED","ansi",true)

end

#  Close the channel:
success = ssh.ChannelSendClose(channelNum)
if (success != true)
    print ssh.lastErrorText() + "\n"
    exit
end

#  Let's pickup the accumulated output of the command:
#  (In this case, it will be the string "FINISHED")

    print ssh.lastErrorText() + "\n"

#  Display the remote shell's command output:
print cmdOutput + "\n";

#  Disconnect
