0.7.0 fails to start (Win7 x64 sp1)

[mas91180]

Hi and let me thank you for this nice program. Decided to upgrade from 0.6.15, but no luck so far.
Here's the part of log pertinent to the problem:

Code: Select all

Starting web-interface on localhost:8125

::INFO::[_cplogging:55] [17/Jun/2012:09:11:37] ENGINE Bus STARTING

  File "cherrypy\process\servers.pyo", line 260, in wait_for_free_port
IOError: Port 8125 not free on 'localhost'

...and it just shutting down after that. Well, I checked with netstat and this port is definitely free, also I tried different ones - same problem. Tried both installation and zip versions. Rolling back to 0.6.15 (same ini) - everything's fine. Any ideas what could be wrong?
Thanks in advance.

What have you filled out as SABnzbd Host in Config - > General ?

Your log says "::1", so I'm wondering ...

localhost

upd: ...and thanks to your question problem solved, changed it to 127.0.0.1 and it started just fine. weird, i believe 'localhost' was there since I don't remember when.

Yep: localhost should work.

When you change back to localhost, do you get the same problem?

yes, works with 127.0.0.1 only
even if I explicitly write 127.0.0.1 localhost in my hosts file, it doesn't seems to resolve it

[sander]

Can you do on the CMD command line:

Code: Select all

nslookup localhost
ping localhost (and then CTRL-C after a few pings)

... and post the output here?

[mas91180]

Code: Select all

>nslookup localhost
Server:  UnKnown
Address:  192.168.0.1

Name:    localhost
Addresses:  ::1
          127.0.0.1

>ping localhost

I think Shypike should have a look at this thread. I'll inform him.

[shypike]

On "modern" operating systems, localhost means both 127.0.0.1 (IPv4) and ::1 (IPv6).
Release 0.7.0 wants to bind to both of those, because various browsers mess up
(some pick ::1, others 127.0.0.1).
The consequence is that the same port should be available on both ::1 and 127.0.0.1
On your system this is not the case, because some other program/service is using ::1:8125
(either that or some networking anomaly).
The work-around is to use another port or set 127.0.0.1 explicitly, like you did.

Can you post the output of

Code: Select all

netstat -aon | find "8125"

@shypike:

mas91180 says he also tried other ports, and that didn't work either. So maybe a (system) problem with binding to ::1 ? Let's wait for his netstat output.

[mas91180]

1 minute after SABnzb shut down, netstat shows just an empty line and exits
