WebGUI not reachable

[Basta]

I can't get the SABnzbd WebGUI running.  I have installed SABNzbd 0.4.8 on a FreeBSD 7.2 system (running freeNAS and followed these instructions http://forums.sabnzbd.org/index.php?topic=2067.0). I can start SABnzbd on port 8080 but I can't reach the WebGUI.

On my desktop PC I try to open the WebGUI on the address http://192.168.1.2:8080/sabnzbd/ but cannot connect to the FreeNAS server.

In order to exclude network problems I used Netcat on my FreeNAS to listen to port 8080 and I see the HTTP request from my PC:

Code: Select all

basnas:~# nc -l 8080

Aslo I can run a webserver on 8080 and access that without problems. Anyone a clue why I can't access the WebGUI?

Please help me ... Bas

[sander]

on the machine running SABnzbd, can you "telnet localhost 8080"?

And: why are you using the parameter "-s 192.168.1.2:8080" in the startup of SABnzbd? Why not leave it out?

[switch]

Try launching sabnzbd like the following:

Code: Select all

/usr/local/bin/SABnzbd.py -s 0.0.0.0:8080

or

Code: Select all

/usr/local/bin/SABnzbd.py -s :8080

This only needs to be run this way once. Use -d -f ~/.sabnzbd/sabnzbd.ini in your init.d script as the tutorial suggests

[Basta]

Can you "telnet localhost 8080"?

No, because telnet s not installed (it's a FreeNAS distribution which is based on a very minimal FreeBSD). What do you want to test with it? Is there an alternative?

Try launching sabnzbd like the following:

Code: Select all

/usr/local/bin/SABnzbd.py -s 0.0.0.0:8080

Did it but the WebGUI is still not reachable. Here is the complete output:

I'm getting crazy. Why doesn't it work?

[sander]

Can you "telnet localhost 8080"?
No, because telnet s not installed (it's a FreeNAS distribution which is based on a very minimal FreeBSD). What do you want to test with it? Is there an alternative?

The purpose of 'telnet localhost 8080' is to test that you can locally reach the SABnzbd server. This is to make sure no IP address mismatch or blocking firewall is involved.


Alternative: "nc localhost 8080".
First run this command when SAB is *not* running. The nc-connect should get refused.
Then start SAB and try "nc localhost 8080" again. It should then get connected (however, strangely enough, SAB won't say anything). Type "GET /" and then , and the connection should close.

Here's my example:
First I try to connect to 4444 (on which nothing is running), which gets correctly refused.
Then I connect to the SAB port 8080, which is accepted (by SAB) and quickly type "GET /" plus , which then closes the connection.
Finally I show that if I type nothing, SAB closes the connection after 10 seconds.

Code: Select all

ubuntu@ubuntu:~$ nc localhost 4444
localhost [127.0.0.1] 4444 (?) : Connection refused
ubuntu@ubuntu:~$ nc localhost 8080

But I don't understand the error.

[sander]

And, like I asked, what do you get if SAB is *not* running and you try the "nc localhost 8080"?

[Basta]

Sorry, it exits without reporting anything.

[sander]

Sorry, it exits without reporting anything.

When? Please post the output here.

And make you test with SAB running, and without SAB running.

[Basta]

I'll be a bit more precise. The netcat exits without anything when SABnzbd is not running. I added the -v option to get more info. The complete log is below:

Code: Select all

basnas:~# nc -v localhost 8080

nc: connect to localhost port 8080 (tcp) failed: Connection refused
Connection to localhost 8080 port [tcp/*] succeeded!

[sander]

OK, that seems OK. Next step: instead of 'localhost', use the LAN IP address of your NAS. So something like:

Code: Select all

nc 192.168.12.34 8080

to see if that works.

[Basta]

No that doesn't work:

Code: Select all

basnas:~# nc -v 192.168.1.2 8080
nc: connect to 192.168.1.2 port 8080 (tcp) failed: Connection refused
basnas:~# /usr/local/bin/SABnzbd.py -d -s 0.0.0.0:8080
basnas:~# nc -v 192.168.1.2 8080
nc: connect to 192.168.1.2 port 8080 (tcp) failed: Connection refused

What does that tell me?

[sander]

No that doesn't work:

Code: Select all

basnas:~# nc -v 192.168.1.2 8080
nc: connect to 192.168.1.2 port 8080 (tcp) failed: Connection refused

basnas:~# nc -v 192.168.1.2 8080
nc: connect to 192.168.1.2 port 8080 (tcp) failed: Connection refused

What does that tell me?

It tells your SAB *is* listening on localhost, but *not* on the IP address 192.168.1.2.

Causes could be:
* your NAS has another IP address, not 192.168.1.2. Check with "ifconfig"
* SAB is not listerning on non-local interface.s Check that you have filled out "0.0.0.0" in the ini and check via SAB's GUI.
* your NAS has a firewall blocking LAN traffic tot port 8080
* your NAS is not listening on 192.168.1.2.
* ...

[Basta]

* your NAS has another IP address, not 192.168.1.2. Check with "ifconfig"

No. IP is really 192.168.1.2 see also below teh outcome of ifconfig

* SAB is not listening on non-local interface.s Check that you have filled out "0.0.0.0" in the ini and check via SAB's GUI.

No. Tried both host 0.0.0.0 and 192.168.1.2 in ini file and in both cases I cannot access the GUI

* your NAS has a firewall blocking LAN traffic tot port 8080

No. If I use netcat on my NAS to listen to port 8080 I see requests from outside my NAS coming in:

Yes but why not ...

[sander]

Well. Difficult stuff. Maybe it's in the cherrypy you use? To find out, create a file testthis.py with contents:

Code: Select all

import cherrypy
cherrypy.server.start()

Then run it with "python testthis.py". That should startup the cherrypy webserver.
Then  connect to localhost 8080, and LAN IP address (192.168.1.2 in your case) 8080 again.

Disclaimer: I'm not sure which version of cherrypy is used; the cherrypy of the OS, or the suff SAB's own subdirectory ...

Both work for me on my Ubuntu with the 2-liner above:

Code: Select all

ubuntu@ubuntu:~$ nc 192.168.1.36 8080

ubuntu@ubuntu:~$ nc localhost 8080

ubuntu@ubuntu:~$ nc localhost 4444
localhost [127.0.0.1] 4444 (?) : Connection refused
ubuntu@ubuntu:~$
