Startup error on OSX

[gobo]

Version: 0.7.0
OS: OS X Lion
Install-type: OSx .app
Are you using IPV6? yes
Is the issue reproducible? yes

I upgraded my Sabnzbd app. It worked fine before, I replaced it with the new version and now I'm greeted with an error when I try to start it:

SABnzbd.py 0.7.0

SABnzbd needs a valid host address for its internal web server.
You have specified an invalid address.
Safe values are localhost and 0.0.0.0

Please restart SABnzbd with a proper host address.

Open a Terminal window and type the line (example):
/CustomApps/SABnzbd.app/Contents/MacOS/SABnzbd --server localhost:8080

Program did not start!

Using that command line does not actually work, the only one that I've found to work is:

Code: Select all

    /CustomApps/SABnzbd.app/Contents/MacOS/SABnzbd --server ::1:8080

Then it works perfectly, but if I then try to start the application again by clicking on it, then it gives me the same error above.

It looks like "localhost" does not resolve on your system.
Does "ping 127.0.0.1" work from a Terminal window?

Nope, that's not it:

Code: Select all

[jeroen@Doc] ~% ping localhost
PING localhost (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.048 ms

After you started it up successfully, which host address is in the sabnzbd.ini file?
Location: http://wiki.sabnzbd.org/configure-0-7

Weird. Now that it did startup succesfully, I can see that host=::1 in the config file, and it start succesfully each time from now on (even without the arguments). Now it also starts even with the localhost argument.
I was 100% sure that it didn't do that before.

[Jazradel]

I was having the same issue on 10.5.8 ppc. My host was 0.0.0.0 in the .ini file, changed it to ::1 and I could start it again.

Edit: Didn't work when I changed it back to 0.0.0.0, but did work with localhost. I have changed it to * and it seems to work fine now.

[Kemik]

I got the same thing. The code suggested in the original post in terminal failed to work. I downgraded to the latest 0.6.* thinking it was a bug in the launch but apparently not.

[shypike]

Some OSX systems don't seem to know their own IP address.
Using 127.0.0.1 should always work.
SABnzbd's top menu symbol (the down arrow) now has a "Troubleshoot" menu, where
you can force 127.0.0.1:8080 to be used.

I have a feeling it's "localhost" which doesn't seem to resolve always.

Adding a Troubleshoot menu in SABnbd's top menu is not helpful if it fails to launch...

[shypike]

Ever since OSX (and Windows too) let the DNS system determine the value of localhost,
things like this can go wrong.

The simplest fix is this:
From a Terminal window type:

Code: Select all

sudo echo 127.0.0.1 localhost >>/etc/hosts


BTW: and error in SABnzbd surfaced when on some Linux systems.
It may have a relation with your issue too.
It's under investigation.

I can't get 0.7.0 to start on my OSX 10.6.4 server either. I was running all the previous versions without any issue before. Here is what I know so far.

• My /etc/hosts file is fine

Code: Select all

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255   broadcasthost
::1             localhost
fe80::1%lo0   localhost

• I had disabled IPv6 but I enabled it and it in my network preference pannel and that had no effect, I still cannot start 0.7.0.

• I can ping localhost and I can also ping 127.0.0.1

• I have tried changing my host entry in the sabnzbd.ini file to 0.0.0.0, 127.0.0.1, ::1, * and my actual local IP address (192.168.1.75). None of these allowed me to start 0.7.0

• I have tried the following CLI startup options

Code: Select all

/Applictions/SABnzbd.app/Contents/MacOS/SABnzbd --server ::1:8080

Code: Select all

/Applictions/SABnzbd.app/Contents/MacOS/SABnzbd --server localhost:8080

Code: Select all

/Applictions/SABnzbd.app/Contents/MacOS/SABnzbd --server 127.0.0.1:8080

Code: Select all

/Applictions/SABnzbd.app/Contents/MacOS/SABnzbd --server 192.168.1.75:8080

Code: Select all

/Applictions/SABnzbd.app/Contents/MacOS/SABnzbd

• With all of those CLI startup options I get the following output in the terminal window

Code: Select all

Suzanne:~ admin$ /Applications/SABnzbd.app/Contents/MacOS/SABnzbd --server localhost:8080

• If I put the --console option on my CLI startup command I get the following

I am at a loss here and I am not sure what my next steps are. I can and have rolled back to 0.6.15 because that is the only backup version I have of SABnzbd. Any ideas, or other directions to go in?

[bunhead]

FOUND IT! It seems my /etc/hosts file was to blame. I was looking at the output of the CLI startup with the --console output and I noticed that SABnzbd was trying to start two instances one for 0.0.0.0 and one for fe80::1%lo0. I have no idea what fe80::1%lo0 is so I made a backup of my /etc/hosts file and then removed the entry and now SABnzbd starts and works just fine .

Code: Select all

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255   broadcasthost
::1             localhost
fe80::1%lo0   localhost

I changed it to

Code: Select all

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255   broadcasthost
::1             localhost

Incase you don't know how to make a backup of your /etc/hosts file here is how you do it.

Code: Select all

sudo cp /etc/hosts /etc/hosts.backup

Then you can modify it using any text editor you like as long as you sudo the command, I like vi because I am old and that is what I am used to

Code: Select all

sudo vi /etc/hosts

SABnzbd starts fine now but I am not sure what, if any implications this will have to other application(s) running on my system. I will update if I find any negative effects.

[shypike]

FOUND IT! It seems my /etc/hosts file was to blame.

Strictly speaking the "fe80::1%lo0" entry isn't wrong.
However, normally there are no localhost entries in /etc/hosts
because DNS is supposed to take care of those.

When I enter all those localhost entries into my /etc/hosts, things keep working as before.

BTW: what is shown when you type?
uname -n
and can you ping the name shown?

[shypike]

I can't get 0.7.0 to start on my OSX 10.6.4 server either.

Same question.
What does "uname -n" show?
And can you ping the resulting name?

[shypike]

Do any of you run VMWare's Fusion on your OSX system?
(I had a lot of problems with Fusion 3 messing up the network stack.)
