Mike,

what I found was that the .ready file was sometimes not created on the SSHFS mounted spool directory; and as it was not there the X2Go print dialogue box would not be shown.  I basically changed the code to the following:


if( $mounts=~m/$spooldir/)
{
     move ("$printdir/$file", "$spooldir") or die "$!: Can't rename $file to $homedir/.x2go/C-$session/$file";
     $file $spooldir\"");

     my $counter = 0;
     while ( ! -f "$spooldir/$file.ready" && $counter < 10 )
     {
        open (RFILE,">$spooldir/$file.ready");
        print RFILE "$file\n$title";
        close (RFILE);
        $counter = $counter + 1;
     }
     if ( $counter > 1 ) { syslog("info", "Failed to write ready file - Count $counter - C-$session/$file"); }
}
else
{
     unlink("$printdir/$file");
}

So at least now it will try a few times and if it does file then a syslog message is produced which OSSEC picks up and alerts us on. I should add that the actual PDF file does make it to the physical client computer. Is that what you have seen ?
