Well it depends on how that login works. AFAIK, there is no universal
standard for firewall logins.

>    - secondly the remote host

Again, it depends on how the login works. Is it a HTML form? Is it regular
HTTP authentication? Is it HTTPS possibly?

> when issuing a CURL FTP put command ?

Ah, you mean step two logins and uploads a file with ftp?

You need to give us more data, we won't be able to provide a good answer
otherwise!

ftp CURLE_FTP_PORT_FAILED after lots of downloads

Hi,

I am using libcurl 7.9.8 at HPUX11.

My program is getting some (many) files from a Windows NT ftp server.

After geeting 2110 files, I am getting the CURLE_FTP_PORT_FAILED error, even
after reseting the curl handle...
Other non-libcurl ftp clients are still able to download files...
Any idea???

Here it is the verbose output of the 2110th file and the 2111th one:

* Connected to [re-used] (10.44.22.26) port 21

> CWD alarmes^M

That is not IPv6-enabled, right?

Does it always fail after exactly 2110 files?

What is the error message associated with this error? CURLE_FTP_PORT_FAILED
can be generated in quite a few places in the code so if you could dig up the
human-readable error message too, it would help a lot.

Also, I noticed that it did "PORT 10,70,40,7,253,11" twice and then the
failing one did "PORT 10,70,40,7,253,12" (increased the port number one

No, indeed. I noticed that it fails around 2050-2150 files

The error is " Too many open files".
However, I am ensuring that I am fclose'ing every FILE* I fopen'ed.
What about libcurl?

I am very sorry. Thak was a copy-paste mistake.

libcurl doesn't fopen() at all, but it uses file handles for sockets etc and
I guess this might concern one of those.

But I'm not aware of any leakage of file descriptors either. Can you add some
kind of check/trace on the file descriptor usage in libcurl? The MALLOCDEBUG
define enables such ones, logged to a file. And then there's the
tests/memanalyze.pl script that analyzed such a log dump.

Does fclose() return an error code? The file system may still be
busy flushing data to the files, especially if you're using NFS
or auditing.

7.10-pre2 on windows...

Hey friends

I've recently received indications that the curl 7.10-pre2 version has some
kind of bugs that shows when run on windows.

I'd therefore like to make an extra request here that those of you who can,
get it, build it and try it. Preferably on windows, but all platforms are of
course fine to try it on.

I don't have any windows machines myself to debug this on, and I can't see
any problems on the Linux and Solaris machines I've tested 7.10-pre2 on.

Curl.h need change ? [was ftp CURLE_FTP_PORT_FAILED after lots o f downloads]

Thanks for your answers.

I was able to find MY error.
In a very specific situation an exception was generated and the
corresponding fclose was not called.

Now, I have got another problem:
I am compiling with HP-UX aCC and I am getting an error when using curl7.9.8
headers.
I need a kind of additional check as the one that occurred  from v1.152 to
1.153 of curl.h.
But I do not know what should be the compiler flag to check !!!!

My compiler does not predefine __STDC__ neither _MSC_VER neither
__cplusplus.
It does not allow to define them either.

Any help?

Meanwhile I slightly changed the curl.h file to force it to compile the line
  #define CFINIT(name) CURLFORM_ ## name 
and it works
