Please help me to make request

Hi!
Please help me to make curl request that can provide file-post http request

So http body must be like this

Content-Type: multipart/form-data; 
boundary=---------------------------53240779711139602362867867
Content-Length: 4579
-----------------------------53240779711139602362867867
Content-Disposition: form-data; name="PAGEID"

6
-----------------------------53240779711139602362867867
Content-Disposition: form-data; name="Upload_LOG"; 
filename="132x64_voicespin.dob"
Content-Type: application/octet-stream

<84> <at> 

html code looks like that

<form action="/cgi-bin/ConfigManApp.com" method="post" 
encType="multipart/form-data">
<table width="700" height="30" border="0" align="center" cellpadding="0" 
cellspacing="0" id="table_logo"  style="display:none" >
<input type="hidden" name="PAGEID" value="6">
<input name="Upload_LOG" type=file size="25">
<input onClick="AddLog()" type="button" value="Upload" name="addlog" 
style="width:80px">

Just add another -F:

curl -u adn:adn -F Upload_LOG= <at> pin.ob -F PAGEID=6 [URL]

Re: curl-users Digest, Vol 56, Issue 1

I thought this would send the "mycsr.csr" file to the remote server for signing. So the two commands I was using to try this were:
====================
# curl --cacert cert.pem --data CertRequest=mycsr.csr -d Mode=newreq -d TargetStoreFlags=0 -d SaveCert=yes --data-urlencode CertAttrib=\r\n https://ca.myserver.com/certsrv/certfnsh.asp

# curl --cacert cert.pem -G -d ReqID=115 -d Enc-bin https://ca.myserver.com/certsrv/certnew.cer
====================

I thought I was getting an error because perhaps the .csr file should be converted to a .pem file first. If this does not do the job can you advise the best way to accomplish this? Again I'm trying to use curl to have a locally generated CSR signed by the remote CA server (MS 2008), and retrieve the signed certificate.

Thanks for any direction you can provide.

That command line only sends five name=variable pairs separated with
ampersands (--trace-ascii shows you that). I don't see how that sends any file
at all to the remote server.

No, this doesn't send any file. See the man page for details on how -d 
(which is the same option as --data) works.

Curl 7.19.2 Crash on opening Ftp second connection while uploading.

Hi Daniel,

Could any help me finding a fix for Crash ?

I am using Curl 7.19.2. Curl 7.19.2 is crashing while uploading a file when using FTP. It working nicely with other protocol https, http and tftp.
I think, there is some problem while opening a data connection for FTP. I could see in ethereal capture that my application is crashing after sending ACK for
server's "Response code: Entering Passive Mode (227)".

Unfortunately in my application, i couldn't use debugger. But using printf, i could manage to see CURLcode ftp_statemach_act(struct connectdata *conn) function which is logging
my printf statement.

Perhaps this issue is already fix. if yes, please provide the patch to fix the problem.

Thanks,

Mohit

You're using libcurl within your application, right? Then I advice you to 
instead use the curl-library list to reach other libcurl users and hackers.

With such a fuzzy description of the problem with no traces or logs of any 
kind, it is impossible to say if this is a new problem or something we already 
fixed. I suggest you try with 7.20.0 and see if the problem remains, and if it 
does you go on to produce a better way for us to understand what you 
experience and post that to the curl-library list.

Fwd: curl 'name look up timeout' error

Forward to curl-users mail list.

---------- Forwarded message ----------
From: wd <wd <at> wdicc.com>
Date: 2010/4/6
Subject: curl 'name look up timeout' error
To: curl-and-php <at> cool.haxx.se

hi,

I use curl_exec in php to get some date from a url like 'http://abc.com/page/1' on an linux server.

abc.com is not exists, I set it in /etc/hosts like '123.23.2.3 abc.com', I can ping this hostname correctly, and never lost any ping package.

But when I use curl_exec in php, randomly got error like this mail title said. The error code is 6.

Then I try to use curl in command line like 'curl http://abc.com/page/1', the same error randomly occur.

The curl version on that server is curl-devel-7.15.5-2.el5 and curl-7.15.5-2.el5.

I've tried download and compile the newest curl curl 7.20.0 by hand, and the error still there.

Some info may be useful:
Red Hat Enterprise Linux Server release 5.2 (Tikanga)
Apache 2.2.11 compile by hand.
PHP 5.2.9
curl-devel-7.15.5-2.el5
curl-7.15.5-2.el5. (and already tried curl 7.20.0)

Why does this happen? Any response would be welcome. thx.

That's probably because of something fishy in your network setup. Like a bad 
DNS, weird firewall or similar.

Curl behavior with and without pipe

Below, you will find a bit of a brain-teaser for me. In the first “curl” command it gives the expected listing of files on the 127.0.0.1 server (with no other output) – however, the second command line (which only adds a stdout pipe to an egrep) gives additional output as if I had turned an option on for it. Any idea why? Also, how would I remove the extra output (which is nice to have in some cases just not this one)? I know that I can go in and possibly analyze what is going on with strace/truss type utilities – but, thought I would try this (possibly) quicker solution first. Thanks in advance for your help.
