What does "HTTP error 0" signify when given as the result of an http test? An empty page? Thanks, Larry Barber

It connected to the server, sent the request, and got no response. Henrik

Hi all When hobbit monitors the https site, it always gets the error " HTTP error 0" like below, I appreciate a lot if anyone can give the solution, thanks https://x.x.x.x/ - HTTP error 0

"HTTP error 0" basically means that Hobbit could connect to the webserver, but it didn't receive any response to the web request it sent. Regards, Henrik

Hi Henrik, I'm with Aaron in same company, the weird thing is, if we use wget, then can still receive data, so not sure what's wrong. Thanks, Samuel Cai

I tried running bbtest-net with debug, and got following: 2008-11-04 04:14:04 1 tests pending - 1 active tests 2008-11-04 04:14:04 Doing select 2008-11-04 04:14:05 select returned 1 2008-11-04 04:14:05 read -1 bytes from socket Seems Hobbit couldn't get anything from that URL, but if I use wget (have to use --no-check-certificate since we tests IP directly), can still get contents. I know this may be more related to the network infrastructure the new Hobbit server is in, but if you got same issue before, please help share your experiences. Thanks, Samuel Cai

Can you try running '~hobbit/server/bin/bbtest-net --version' just to
check the version number of your OpenSSL library ?
And can you get data using just the openssl client utility ? Like this:
openssl s_client -connect 10.20.30.40:443
(replace the IP with that of your server). If that succeeds and shows
you the server certificate then enter
GET / HTTP/1.0
and hit <enter> twice - this mimicks a simple HTTP request. Does that
work ? And how long does it take to complete ?
Finally, you could try modifying the code in hobbit-4.2.0/bbnet/contest.c
In there is a routine called "socket_read"; delete the version in your
file and replace it with the version below. Recompile with "make bbnet-build"
and copy the new bbnet/bbtest-net program to ~hobbit/server/bin/ . Then
run it with the "--debug" option enabled, like
bbcmd bbtest-net --noping --debug HOSTNAME
to run the test of just this one host. Hopefully that will print out
some more info about what happens with that read that returns -1.

Henrik

Thank you Henrik, this is the root cause! We did not install openssl dev package, the "bbtest-net --version" only returns hobbit version. After we installed and recompile, problem is gone! Thanks again.
