Zabbix interfering with sabnzbd web UI

[spanky85]

Hi, I've noticed something quite strange. I'm running Ubuntu 10.10, with sabnzbd 0.6.0RC2. I also have installed Zabbix 1.8.2. If I go to the web interface of sabnzbd (plush theme) whilst I have Zabbix open in another tab, looking at any of the pages in Zabbix's 'configuration', I get this error from sabnzbd:

Code: Select all

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Traceback (most recent call last):
  File "/usr/share/sabnzbdplus/cherrypy/_cprequest.py", line 593, in respond
    self.process_headers()
  File "/usr/share/sabnzbdplus/cherrypy/_cprequest.py", line 661, in process_headers
    self.cookie.load(value)

  File "/usr/lib/python2.6/Cookie.py", line 455, in set
    raise CookieError("Illegal key value: %s" % key)
CookieError: Illegal key value: cb_/zabbix/hostgroups.php_parts

I have reported the problem on the Zabbix forums (here: http://www.zabbix.com/forum/showthread.php?p=83622) since I assumed it was Zabbix setting cookies incorrectly, but the response there has been that it's more likely to be sabnzbd's fault. Any ideas as to what's going on?

It's 100% reproducible, but not a super-high priority since the workaround is simple; view a different page in Zabbix

Looks like a cookie naming clash.
You may be able to work around it by using "localhost" for one program and "127.0.0.1" for the other.

BTW: both programs are probably incorrect.
Both are assuming that they are the only service running on "localhost".

Ah, that makes sense! And it's correct! Typing in the IP of the server for one program and the host name for the other works. Thanks!

We should do a clean up of the cookie handling, it's a bit messy right now.
But not any more for the pending 0.6.0 release.
Thanks for the reminder.

@spanky85 & offtopic:

How do I proceed installing and configuring Zabbix after "sudo apt-get install zabbix-server-mysql"?

Thanks

I can't remember exactly what I did, but it was along the lines of:

Install Zabbix, the agent (to collect stats) and the frontend (to view them):

Code: Select all

sudo apt-get install zabbix-server-mysql zabbix-agent zabbix-frontend-php

Fire up localhost/zabbix, log in as admin (password is zabbix), then follow this guide roughly to get it set up:
http://www.zabbix.com/documentation/1.8 ... quickstart

There's a bit more work to do for configuring email alerts, I needed to fiddle some php settings (the web interface warns you which ones), and I had to disable some of the default checks, but it seems to monitor a sensible set of stuff by default which is nice. Setting up log monitoring requires a little more work too. Oh, and I think I had to replace 'localhost' with '127.0.0.1' in the server config file, and replace 'localhost' with 'Zabbix Server' in the agent config file, if I remember rightly.

The actual cookie name giving the error is "cb_/zabbix/media_types.php_parts"

I find it hard to believe that sabnzbd has a conflicting cookie with that name, but rather it doesn't like part of the name, ie. forward slashes
