It's really simple, we just retrieve a given url passing in the username/password for basic authentication. I've sold 300 systems, and it has run fine on all of them, until now. On one system, which is otherwise identical to the all the others, it appears that libCurl is *not* sending the basic authentication username/password for no apparent reason. The command line utility works fine, though. I even created a sample app with hardcoded values to be 100% sure everything is correct. So I'm totally baffled. This is the command line that works: curl -v -u "dceadmin:dcepass" -o foo2.jpg " http://192.168.0.82/low=/SnapshotJPEG?Resolution=320x240&Quality=Standard" and returns: OpenSSL/0.9.8h zlib/1.2.3 < HTTP/1.0 200 OK % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed Paul Bergen 2008-11-29T01:31:29 http://comments.gmane.org/gmane.comp.web.curl.library/21546 Not sure if this is a bug or just me making a mistake. I was using libcurl to do a multi part form upload using HTTP post. It worked 95% of the time. Then occassionally it would fail with the error "Failed writing body". It was occurring when libcurl was parsing the last received HTTP response (the "HTTP OIK" response). I tracked it down to sendf.c. When it was pushing the data out, whatever it was writing to, didn't accept all the bytes. Then, I realised that I hadn't actually set CURLOPT_WRITEFUNCTION, so it was set to the default (which I think writes to a file). However, I also hadn't set CURLOPT_WRITEDATA. So, anyway, I explicitely set CURLOPT_WRITEFUNCTION to point to a dummy function which just discarded the data, and my problem went away. So my questions/comments are: 1. Do you explicitely need to set either/both CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA when using HTTP POST? I hadn't set them because I wasn't interested in the response from the server (beyond whether it returned HTTP 20 John Wood 2008-11-28T16:08:18 http://comments.gmane.org/gmane.comp.web.curl.library/21542 There have been reports of this error when using curl with FileZilla server: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number or, more generally, Unknown SSL protocol error (e.g. http://curl.haxx.se/mail/lib-2008-01/0338.html and following). I'd like to clarify that this is the same problem that has been reported for FileZilla server when using implicit SSL. FileZilla server assumes that the data channels are, by default, in clear mode. One workaround is to use explicit SSL on the server. Another workaround is to force curl to use a 'PROT P' command--for example, using -Q 'PROT P' on the command line. This does curl_easy_setopt(curl, CURLOPT_SOURCE_QUOTE, ...); in libcurl. For the record, -Q '+PROT P' did not work; apparently the command is sent too late. In 2007 there was some talk on this list of always sending a PROT command after a PBSZ, even in implicit SSL mode. I think this would be a good idea.

I am writing a program that uses the libcurl to fetch a bundle of urls using the multi interface. Now, many of the urls I am fetching belongs to the same domain. Example: www.aaa.com , www.aaa.com/1/ , www.aaa.com/2/ I can see that all DNS requests are sent at the beginning (probably right after calling curl_multi_perform()) that's b/c I am using asynchronous name resolves. I have noticed that the libcurl issues a different dns request for every URL in the multi handle although many of them share the same domain. This means that for the example above I get to see 3 DNS requests for www.aaa.com. I am wondering if there is an option that I can use to tell the libcurl to issue only one DNS request for www.aaa.com and only when response arrives perform the HTTP requests for all the URL's sharing the same domain ? Thanks, Tsachi Tsachi 2008-11-26T10:41:01 http://comments.gmane.org/gmane.comp.web.curl.library/21532 Hi, Background (for sake of context) - I am trying to create a VNC solution which uses tightvnc. The idea is basically that the TightVNC server does a reverse connect to a VNC Reflector (so that the server doesn't have to listen on any port). Then a viewer can do a connect to the VNC Reflector and then basically see the desktop where TightVNC server is running. VNC Reflector acts as a *client* to the TightVNC server and as a *server* to a VNC Client. Basically, this lets us have a solution where the reflector can be on a remote server and the users don't have to listen to any port. I got this working against a squid proxy (TCP tunnel). Issue - Proxies : Libcurl is used in a modified TightVnc Server code, where curl does the initial handshakes - reverse connection - , tunneling (CURLOPT_HTTPPROXYTUNNEL) and gives back the raw socket for the TightVNC server to use. The issue is this, there seems to be quite a few good proxy servers / firewalls out there, which can figure out if the tunnel is actually carr Bharat Varma 2008-11-26T08:25:46 http://comments.gmane.org/gmane.comp.web.curl.library/21527 I'm using curl via the cmd line/batch file in Windows XP. I have it pulling a series of png files from a web server via the HTTP command: "curl http://webserver/file.png -o c:\local\file.png" etc. The files are dynamically created and sometimes there is 1 file and other times there are up to 20. Right now I have curl pulling all 20 files, but if the file does not exist on the server, curl creates an empty (1 kb) png file on the local server. How can tell curl to ignore these empty files, or do something within the batch file to ignore or delete these files. Thanks.

Linden Lab made their viewer open source and provides binary downloads for several platforms, including linux 32bit. I'm working with 64bit myself and that works perfectly, compiled from source. The binary distributed by LL links with a curl library that is configured with --enable-libcares. They also distribute this shared library (along with a lot of others) and have people link with those libraries when they start the viewer. However, the debian team of omvviewer wants to use as much as possible the shared libraries that are provided by debian, of course. Several packages have already been added to debian for this reason. The problem at the top of our TODO list is currently: the libcurl package in debian is not using libcares. This results in the viewer freezing for a whole second, sometimes even more, several times per minute.

Its great. But One of my program just wont work with curlLib. I compile it with curl.lib (static link win32 program), curl always report can’t reslove domain name. It confuse me for several days. Soon I found out, it is because the iphlpapi.dll which is in the same directory with my program. After I remove iphlpapi.dll, my program with curlLib works fine. ~~~ Why? Is it "work as intended"? Thanks Tomasen Tomasen 2008-11-22T17:53:37 http://comments.gmane.org/gmane.comp.web.curl.library/21498 Hi All, Currently I am porting curllib to a proprietary ARM platform. In this platform I have only asynchronous sockets in which all the socket events (Connect, Read, Write and Close) are notified via events. As for my understanding the the current curllib implementation expects the socket to be synchronous or blocking at certain levels (At least for connecting). Can anyone suggest me some idea or specific places/modules/functions where I can start customizing curllib to support asynchronous sockets. Regards Kulanth Kulanthaivel 2008-11-22T09:16:56 http://comments.gmane.org/gmane.comp.web.curl.library/21495 Looks like something goofy happened to test cases 35, 262, 545 and 552.

Josef Wolf 2008-11-19T22:54:17 http://comments.gmane.org/gmane.comp.web.curl.library/21484 Hey I just wanted to mention that if you want to see my 38 minute presentation of curl and libcurl I did in December 2007, the video of my talk is now available online here: http://daniel.haxx.se/blog/2008/11/19/curl-presentation-video/ Daniel Stenberg 2008-11-19T14:23:16 http://comments.gmane.org/gmane.comp.web.curl.library/21457 First an outline of what I'm trying to do. 1. FTP Access to browse by GUI interface the ftp site in question. 2. Get files from the FTP site and download them. I'm using PureBasic, I can understand C & VB so if you have code examples of this following problem I'd be grateful if you could post them in those languages, if not I'll take anything I can get. I'm stuck on step 1, no matter what I throw at libcurl it won't CWD and won't list the new directory, could someone show me a clear example of a persistent (constant just in case I used the wrong word) connection changing Up and Down the directory structure, without having to disconnect and log back in with the new path appended to the url. I've seen a few people having problems in this area over my 24+ hours trying to figure this out, the only solutions I've found is diconnecting re-logging in with the CURLOPT_URL appended with the folder, this is unacceptable I don't want to disconnect and reconnect for each folder, I would like the connection to stay.
