ykclient fails, but it shouldn't!
i get the following when trying to authenticate to a local authentication server:
[gmatz@bunnybear ykclient-2.2]$ ./ykclient 1 frrdebhfhebhtdvevvthgktfutbigvkufb
Input:
client id: 1
token: frrdebhfhebhtdvevvthgktfutbigvkufb
Verification output (101): Could not parse server response

however my webserver log says:

strace says that ykclient (libcurl) is initiating a HTTP/1.1 call (its default), so i tried a few HTTP/1.0 GETs by hand and it looks like it fails in HTTP/1.1 GETs and only works with HTTP/1.0 GETs

[gmatz@bunnybear ykclient-2.2]$ telnet localhost 8080
Trying 127.0.0.1...

I added a line to ykclient.c to force a 1.0 connection:
curl_easy_setopt (ykc->curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);

but I still get a 1.1 response from my tomcat 6 server.

BTW, does anyone know why the server is hard-coded in ykclient? why it doesn't take command line params?

any help here would be much appreciated.

Regards,
Guy

I rerun Guy's test with ykclient SVN revision 59 (latest as of today). It looks like there is some problem parsing out lines of response.
Here's the output of ykclient run with debug enabled. Notice how the status variable has length of 51 and contains both status=... and h=... lines.

./ykclient 2 tgueneblcteluhgudfnbbiffevgddlifgnngiekvuiuu
Input:
client id: 2
token: tgueneblcteluhgudfnbbiffevgddlifgnngiekvuiuu
debug: ykclient.c:399 (ykclient_request): server response (83): t=2009-04-30T10:16:03Z0613
status=REPLAYED_OTP
h=BWwOiYTKijmo3SJCmUT1XyMLGPY=

debug: ykclient.c:412 (ykclient_request): parsed status (51): status=REPLAYED_OTP
h=BWwOiYTKijmo3SJCmUT1XyMLGPY=
Verification output (101): Could not parse server response

And it looks like you've found a resolution to the issue! Thanks so much, Mr. Sushkin! It's a pleasure to be a part of the Yubico community with such helpful people such as yourself! If only there was a "pat on the back" emoticon . . . I would give you *two* of them!

Thanks again,
Guy Matz
