#18803 [Opn->Csd]: FTP function ftp_rawlist takes very long in some cases

ID: 18803 Updated by: kalowsky@php.net Reported By: dennisre@gmx.de -Status: Open +Status: Closed Bug Type: FTP related Operating System: red hat 7.1 PHP Version: 4.2.2 New Comment: I have now tried this on 3 different architectures, all with local ftp servers, all downloading a 15MB file. It takes mere seconds on each of them. MacOSX 10.1.5 FreeBSD 4.6 Windows2000 I cannot reproduce either of these two problems on any of these architectures. Thus I believe it is an end user configuration and not a PHP bug. I've even been using your test script. Previous Comments: ------------------------------------------------------------------------ [2002-08-10 07:18:10] wez@php.net If it is only a problem when using a local server, perhaps you should check your DNS settings on that machine: I suspect that your ftp server is trying to reverse map the ip address of the machine running your script and that is the cause of the delay. There are two solutions: correct the DNS configuration, or disable name resolution and reverse mapping in your ftp server configuration. ------------------------------------------------------------------------ [2002-08-09 21:15:58] dennisre@gmx.de I am pretty sure that there is a problem with PHP. I was able to reproduce this on Windows 2000 if I use the local FTP server. It's the same with Red Hat 7.1. If I use the local FTP server it doesn't work, if I use an non-local FTP server it works. ------------------------------------------------------------------------ [2002-08-09 10:18:56] kalowsky@php.net I can't reproduce this and you can't seem to on other machines. I'm going to say this looks like a local user configuration issue, and not a PHP issue. ------------------------------------------------------------------------ [2002-08-09 10:14:10] dennisre@gmx.de I have tested it with an IIS 5.0 FTP Server and it seams to work. ------------------------------------------------------------------------ [2002-08-09 00:29:02] kalowsky@php.net yet again, unable to re-produce on any of my test machines. Can someone with Linux try this as well? And can you please try using a non-ProFTPd server? Just curious if it's specific to ProFTP or not. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
