[hobbit] HTTP error 0

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.

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,

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.

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.
