[RESOLVED] ssl_error_no_cypher_overlap

Post by teracow »

Hi all,

just recently started getting this error when attempting to login via HTTPS to Sab (v0.7.9) via Firefox (v18.0.1)
Image

from the Sab log:

Code: Select all

2013-01-28 05:44:34,810::INFO::[_cplogging:55] [28/Jan/2013:05:44:34] ENGINE Bus STARTING
2013-01-28 05:44:34,886::INFO::[_cplogging:55] [28/Jan/2013:05:44:34] ENGINE Started monitor thread '_TimeoutMonitor'.
2013-01-28 05:44:34,989::INFO::[_cplogging:55] [28/Jan/2013:05:44:34] ENGINE Serving on 0.0.0.0:8800

2013-01-28 05:44:35,099::INFO::[_cplogging:55] [28/Jan/2013:05:44:35] ENGINE Bus STARTED
which isn't showing my attempt to access the login page via HTTPS (port 9090).

HTTP (via port 8800) login works fine.

my server.cert and server.key files appear to be fine as SickBeard logs in correctly using this same certificate.

After spotting a post about a similar issue, I've checked in FireFox about:config that:
security.ssl3.rsa_rc2_40_md5 = true
security.ssl3.rsa_rc4_40_md5 = true
This setup WAS working, then suddenly stopped. The only change I had made was to alter the autoProcessTV.cfg file to communicate with SickBeard using SSL (e.g. ssl=1)

Does anyone know what I'm doing wrong?

Thanks. :-\

I have no idea. Have you tried Chrome?

I'm running Kubuntu 12.10 so I installed Chromium...

Did you switch from http to https using the same port and the same browser?
Browsers can be very stubborn about such changes.
You should clear the browser's cache and try again.

no, I had HTTP working on 8800, then enabled HTTPS on 9090. HTTP access worked for several days and HTTPS access worked for 2 days.

Then yesterday, the HTTPS access stopped working. It doesn't work on any machine on my LAN or from my tablet or phone.

The Chromium install I did this morning started with an empty cache. The only page I tried to access with it was Sab via HTTPS. It failed with the provided error. So, it's unlikely to be a browser-cache issue.

Is the problem on the browser's side, or on the server (SAB) side?

Maybe you can run sslscan against SABnzbd?

Code: Select all

PS: do you use your own server.cert and server.key ? If so, what happens if you don't use them (so go back to a more default SAB)?

I'm just using the default cert with Sab. I haven't yet generated my own.

So ... what is your own conclusion from the first sslscan?

That would be my guess too.

So the problem is on the side of SAB? In the program files, in the sabnzbd.ini, in a library, or something else?

I would do this: move sabnzbd.ini, get a fresh SAB tar.gz, unpack it in some directory, run it (should start the wizard), and then check if HTTPS works correctly.

okiedokie... at this point I should probably mention that this Sab is running on a QNAP NAS (installed via qpkg).

I downloaded the current Sab python scripts, unpacked them then moved them to the NAS.

I stopped the current Sab service. Then started the new install:

So, from my trusty PC, I goto

Code: Select all

http://talia.:8085
and get no response.

I ran sslscan again - no response.

My understanding from the QNAP forum is that Sab runs inside a wrapper but essentially runs as it normally would, upgrades apply correctly, and all that jazz.

However, I don't know what goes on behind-the-scenes here to determine what the wrapper configures in the NAS (firewalls and such). I suspect that the selected port needs to be opened as it's not reachable:

Code: Select all

$ nmap talia. -p8085

Starting Nmap 6.00 ( http://nmap.org ) at 2013-01-28 09:38 EST
Nmap scan report for talia. (10.0.0.2)
Host is up (0.00011s latency).
PORT     STATE  SERVICE
8085/tcp closed unknown

Nmap done: 1 IP address (1 host up) scanned in 0.03 seconds
So I modify the new Sab config to use the old Sab port 8800 and start it running again. When starting up, it uses the 8800 port. Same thing - not reachable and shown as closed in nmap.

Should I post this one back on the QNAP forum?

Wait: have you filled out 0.0.0.0 as listening host in the SABnzbd wizard? Double-check for that: can you access over plain HTTP?

I couldn't get any access to Sab via the browser. So I haven't been through the wizard config. My checks were only using HTTP.

Make sure SAB is accessible from other systems, make sure HTTPS is running and try it from your webbrowser. And only if you get the same error message, run sslscanner against the HTTPS port of SAB.
