I have 3 machines(A, B & C) connected to a Router. A,B & C are in same subnet. All these three machines are interconnected using STAF. I am using machine A as an FTP server & machine B as an FTP client. Using STAF command from machine CI am starting FTP program (TCL script) on machine B.
Now the question is, How C will know whether FTP traffic is flowing between A & B?
The ftp package allows you to specify a progress monitor callback in the ftp::Open
command:
package require ftp
proc progressMessage {bytesSoFar} {
puts "Transferred $bytesSoFar; looking good..."
}
set handle [ftp::Open $A $user $pass -progress progressMessage]
# Everything after this is just standard for the ftp package
if {$handle < 0} {
error "could not connect"
}
if {![ftp::Get $handle $remoteFile $localFile]} {
ftp::Close $handle
error "could not transfer"
}
ftp::Close $handle
puts "Transfer completed"
This will print a message every time a chunk is transferred (the chunk size is configurable in the options to ftp::Open
via the -blocksize
option; it's 4096 by default). On modern networks, this is probably going to write messages very rapidly…
package require ftp
set handle [::ftp::Open $host $user $passwd]
if {$handle < 0} {
error "Connection refused!"
return 0
}
