It always takes me a ftp shell script with error handling while to find the details in the Net::FTP docs so I thought I'd post here: Initial ssis ftp task error handling Connection: the connection is established when you create the object.

The error message can be accessed using the 'message()' method.

Re: Net::FTP pwd bug? by mikeock (Hermit) on Oct 12, 2005 at 19:05UTC When using this module. I cannot get the pwd command to work. I am connected to an ftp server and am trying to use $ftp->pwd() and I get nothing in return. Is this dumping to a default variable that I am missing or is this really a bug?[reply][d/l] Re^2: Net::FTP pwd bug? by marto (Bishop) on Oct 12, 2005 at 22:30UTC Hi, If you are following the above code try something like : #!/usr/bin/perl use Net::FTP; my $destserv="ftp.myhost.com"; my $destuser="username"; my $destpass="password"; $ftp = Net::FTP->new($destserv) or die "error connecting\n"; $ftp->login($destuser,$destpass); my $mypath = $ftp->pwd(); $ftp->quit(); print "FTP Path: $mypath"; [download] Keep in mind that this is untested, its late and I am seriously sleep deprived.Have you checked out the documentation?

My code is basically along the following lines: my $ftp = Net::FTP->new ("mainframe.com", Timeout => 20); if (! $ftp) { logMessage ("Could not connect to host: $!"); return; } if (! $ftp->login ("paxdiablo", "demigodemporeroftheuniverse")) { logMessage ("Could not log in to host: $!"); $ftp->quit (); return; } if http://stackoverflow.com/questions/9029398/error-reason-from-perl-netftp (! $ftp->put ("myfile.txt", "'CANT.WRITE.TO.THIS'")) { logMessage ("Could not put file: $!"); $ftp->quit (); return; } I know I can't create the data set CANT.WRITE.TO.THIS since I don't have the required permissions but, when I try, the only message I see is: Could not put file: There is no indication in $! as to what the problem was. I've looked in the Net::FTP doco and all it says is: put ( LOCAL_FILE [, REMOTE_FILE ] )Put a file on the remote server. LOCAL_FILE may be a name or a filehandle. If LOCAL_FILE is a filehandle then REMOTE_FILE must be specified. If REMOTE_FILE is not specified then the file will be stored in the current directory with the same leafname as LOCAL_FILE.Returns REMOTE_FILE or the generated remote filename if REMOTE_FILE is not given. I also cannot find anything there about retrieving the specific error (like $ftp->getLastError() or something similar). How can I indicate to the user why the transfer failed? On an earlier iteration, I resorted to putting the file, then getting it again and checking contents locally. I'd really rather not have to inflict such kludgy code on people again. perl error-handling ftp mainframe share|improve this question edited J
when local file does not exist - PERL Modules I have a problem getting an error message using Net::FTP when the local file does not exist. $! seems to be empty, and $ftp->message() returns a message from a previous $ftp->cwd, not from http://www.justskins.com/forums/net-ftp-error-when-43836.html $ftp->put. For example: $ftp->cwd("$fdir"); $ftp->put("$file"); $err=$!; $fer=$ftp->message(); print "put $file failed $err: $fer"; What I http://www.tek-tips.com/viewthread.cfm?qid=1545651 get is: Cannot open Local file test.txt: No such file or directory at test.pl line 36 put test.txt failed : CDUP command successful. The "Cannot open" probably went to STDERR, but I can't seem to capture that with the above. Is this a bug? Suggestions?...

Is this a bug? > Suggestions? Here the corresponding code from Net::FTP: unless(sysopen($loc, $local, O_RDONLY)) { carp "Cannot open Local file $local: $!\n"; return undef; } } so the error message goes to STDERR via carp as you suspected. $! is reset somewhere in between. So you can either test the existence of the local file yourself before trying to send it (perhaps the best method), or wrap the

Here's my small ftp script within perl:open(FTP_PIPE,"|ftp -n -i 11.11.111.11");print FTP_PIPE <
