Hello Wise Monks:

I am still investigating the problem you can find in the following post: "Question about FTP.pm rename operation" made by me. I have new questions about how the FTP.pm module works. To make a connection I have the following code:

$self->{ftp} = Net::FTP->new($host, BlockSize => 32768, Timeout => 120
+)

[download]

I have found that the FTP.pm constructor opens a socket to the port 21 with a Blocksize 32768, using tcp and a timeout of 120. Only the timeout part interest me for the moment.

Now the question is:

1.- żIs this the equivalent to do an ftp -T 120?, -T is the timeout option on the ftp command.

EDIT 1:

Thank you Corion. What I try to demostrate is that the following FTP bug: "4500116 ftp -T <timeout> is broken, ftp client does not exit upon network disruption" that can be found on a Solaris 8 System that is not properly patch, can affect a perl program that uses FTP.pm.

The problem is that I have received a "550: No such file or directory". error after a rename operation, however the file has been renamed correctly. This happens once per 2 to 3 months.

The hipotesis is: We send a file but just after the transference is finished but before the server close all and send the successfull return we have a puntual network disruption but because the timeout bug the conection remains connected and after a timeout sends "550: No such file or directory."

This may not be the place to ask this, sorry if its the case, but I am hoping that others may had the same problem.
