#11000 [Com]: ftp_connect(...) produces ftpbuf 0 "error"

ID: 11000 Comment by: tiziano at m4driving dot sm Reported By: kniprath dot l at wver dot de Status: Closed Bug Type: FTP related Operating System: NT 4.0 PHP Version: 4.0.4pl1 New Comment: I'm using PHP 4.1.1 on a FreeBSD machine. I have a script that basically connects to a ftp server, does the login, gets a file and then quits. It worked fine for over a month, but now it outputs this error: Warning: Unable to find ftpbuf 0 in /path/script.php on line x line x is $login_result = ftp_login($conn_id, "$ftp_user", "$ftp_pass"); The ftp server I'm trying to connect to is working as I can connect to it with a ftp client. Other public ftp servers work fine Anybody who can help?

Does fopen("http://...") or fopen("ftp://...") work for you? --Jani ------------------------------------------------------------------------ [2001-07-22 06:15:50] venaas@php.net What happens I think, is that ftp_connect uses gethostbyname to look up the name, it's called with 127.0.0.1 if you specify that. It looks like gethostbyname tries to look up the address for 127.0.0.1 and if it can't contact any nameservers it simply fails. If you use localhost there is probably something like the host file on UNIX, or maybe it is hardcoded, that says that localhost is 127.0.0.1. The implementations I've seen of gethostbyname will notice that it's an IP address and do no lookup, this might not be the case on NT 4.0... If this is a general problem (bug #11025 is similar), I suggest we fix it by calling php_network_getaddresses() rather than doing all the work in ftp.c. php_network_getaddresses() avoids gethostbyname() on IP addresses. fopen uses php_network_getaddresses(). If fopen("ftp://127.0.0.1/...") or http://... works for you I'll fix this for ftp_connect() ------------------------------------------------------------------------ [2001-07-21 21:32:57] andy@php.net Are you saying that 127.0.0.1 only works when you are connected to the internet, but localhost works anytime? ------------------------------------------------------------------------ [2001-05-21 22:30:13] kniprath dot l at wver dot de Now the third answer for sniper@php.net (Hi Jani, I saw your question unfortunately just after I sent my last report): I used the ftp-server WAR-FTPD 1.67-05 (freeware, downloadable from http://www.jgaa.com) and tried it localy installed on my NT4.0 Worsstation with an external NT4.0 Intranet-Webserver (Apache with PHP 4.04).At home I used a Windows 2000 Workstation with local running Apache and PHP 4.0.4 first, 4.0.5 after a meanwhile update. The original error-message on all configurations was: "Warning: Unable to find ftpbuf 0 in e:\eigene dateien\php\liegenschaften\upload.php4 on line 10" Some new information: To my surprise this error does not occur at home, when I am connected to Internet. After dialing in the script runs also with "127.0.0.1" without any warnings, after shutting down the Internet-connection only $ftp_server = "localhost" or $ftp_server="#DNS_name_of_server#" is accteptd. This is also the reason for my second "workaround" as described before, this is no one, because '127.0.0.1' is only accepted when internet-connection is open. Hope, this will help you! bye... kni ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
