Hi Monks

I am trying to use Net::SFTP to send a file from one server to another.

The script I have written works fine when called from the command line, but wont work when called from a web browser.

Originally I got an error and had to create the directory /var/www/.ssh for the apache user. Now I don't get any errors, it just hangs.

I assumed it was to do with permissions, so I tried a couple of things. I added the apache user (temporarily of course) to the root group, but that didn't fix it. So then I gave the apache user shell access (temporarily), su'ed to apache, ran the script and it worked. I can't work out why it won't work when run from a web browser. Code is below:

#!/usr/bin/perl -w

  use Net::SFTP;

  my $upload_dir = "/var/www/vhosts/domainname/httpsdocs/companyname/t
+mpfiles";

  print "Content-type: text/plain\n\n";
  my $filename = "2007-03-27-0088.PDF";
  my $sftp = undef;
  my %args = (user => 'username', password => 'password', debug => 1);

  eval{$sftp = Net::SFTP->new("domainname", %args);};
  if ($@) {
    print "Error: cannot connect to SFTP server. $@\n";
    exit();
  }

  eval{$sftp->put("$upload_dir/$filename", "temp/$filename");};
  if ($@) {
    print "Error: cannot copy file to the SFTP server\n$@\n";
    exit();
  }

  print "Complete\n";

The debug output is as follows:

Any help will be greatly appreciated. I found a few people on google who experienced it hanging at the same point as me (sftp: Sending SSH2_FXP_INIT), but no solutions.

Many thanks

James
