Hi,

I'm trying to automatically download log files from our video conference servers. When I try this with a browser is works (authentication -> save file as).

Now I want to use the cURL command in a script to get the files but it wont work. Here the command I use:

curl --anyauth --insecure --proxy-user 'xxx:yyy' --proxy-ntlm --proxy 'http://x.x.x.x:8080/' --connect-timeout '10' --user 'authname:authpw' --output 'output.txt' https://x.x.x.x/localcdr.csv

The result in the output.txt file = 401 Unauthorized - User authentication is required.

Now the tricky part: 1 of the 7 servers is returning the file with the above command, the other 6 wont :(
With a browser => they work.

Who can help me or has some tips?

Thanks in advance

May find a way out of this fuzz by using sniffer like Wireshark (http://www.wireshark.org/) to see what's the difference between 1 and 6 servers.

I'd rather said servers check some secondary attributes like User-agent or Cookies, you may never guess that without sniffer :)

This was a good hint. I didn't do a sniff but checked the headers with another tool. Result: our network guys made an error in the authentication module.

Thanks snrudda
