URL handling failure when API is specified within .zbx.conf #6

Closed jwieder closed 5 years ago

jwieder commented 6 years ago

When specifying API configuration details within a .zbx.conf file, all zabbix-gnomes scripts result in one of the errors specified below.

When "api=" is specified with a protocol (http://zabbix.website.com) as per the documentation, this error is received:

Traceback (most recent call last): File "./zhostfinder.py", line 114, in zapi.login(username, password) File "/usr/lib/python2.7/site-packages/pyzabbix/init.py", line 68, in login self.auth = self.user.login(user=user, password=password) File "/usr/lib/python2.7/site-packages/pyzabbix/init.py", line 156, in fn args or kwargs File "/usr/lib/python2.7/site-packages/pyzabbix/init.py", line 101, in do_request timeout=self.timeout File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 507, in post return self.request('POST', url, data=data, json=json, kwargs) File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 464, in request resp = self.send(prep, send_kwargs) File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 576, in send r = adapter.send(request, **kwargs) File "/usr/lib/python2.7/site-packages/requests/adapters.py", line 415, in send raise ConnectionError(err, request=request) requests.exceptions.ConnectionError: ('Connection aborted.', gaierror(-2, 'Name or service not known'))

When "api=" is specified withOUT a protocol (zabbix.website.com), this error is received:

Traceback (most recent call last): File "./zhostfinder.py", line 114, in zapi.login(username, password) File "/usr/lib/python2.7/site-packages/pyzabbix/init.py", line 68, in login self.auth = self.user.login(user=user, password=password) File "/usr/lib/python2.7/site-packages/pyzabbix/init.py", line 156, in fn args or kwargs File "/usr/lib/python2.7/site-packages/pyzabbix/init.py", line 101, in do_request timeout=self.timeout File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 507, in post return self.request('POST', url, data=data, json=json, **kwargs) File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 450, in request prep = self.prepare_request(req) File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 381, in prepare_request hooks=merge_hooks(request.hooks, self.hooks), File "/usr/lib/python2.7/site-packages/requests/models.py", line 304, in prepare self.prepare_url(url, params) File "/usr/lib/python2.7/site-packages/requests/models.py", line 361, in prepare_url "Perhaps you meant http://{0}?".format(url)) requests.exceptions.MissingSchema: Invalid URL u'zabbix.website.com/api_jsonrpc.php': No schema supplied. Perhaps you meant http://zabbix.website.com/api_jsonrpc.php?

I am able to connect successfully by either passing all authentication variables as command line arguments. I can also connect by pulling username & password from $HOME/.zbx.conf and passing the API URL as a command line argument. This would seem to suggest that there is a formatting issue with the api variable when retrieved from ini-style configuration files, rather than an environment-specific issue on my part, however I could easily be wrong and I do not have a ton of time to troubleshoot ATM ( I will update if I am able w/ additional info).

For example:

# ./zhostfinder.py -uzabbixUser -pzabbixPassword ahttp://zabbix.website.com -m -S foo
Error: Could not find any hosts matching "foo"

# ./zhostfinder.py -c $HOME/.zbx.conf -ahttp://zabbix.website.com  -m -S foo
Error: Could not find any hosts matching "foo"

The instance I am using does not use SSL to connect, so my $HOME/.zbx.conf looks like this:

[Zabbix API]
username=johndoe
password=verysecretpassword
api=http://zabbix.mycompany.com
no_verify=true

Error occurs with and without trailing / on api url and with or without the inclusion of the irrelevant-for-me no_verify flag.

Error occurs in CentOS 7 with Python 2.7.5 with th following modules installed:

Hi Josh,

Thanks for your report! I've just installed a clean CentOS7, updated all the packages with yum and installed the latest pypi versions of pillow and pyzabbix.

Unfortunately, I'm not able to reproduce the errors you are experiencing. Both http:// and https:// work fine for me.

The error you are getting (requests.exceptions.ConnectionError: ('Connection aborted.', gaierror(-2, 'Name or service not known'))) seems to indicate an issue with hostname resolving, however you indicate this works fine when supplied as a commandline argument. The only I can think of right now that might be troubling you could be hidden control chars in the .zbx.conf file which might change the name in a way that is not visible from human eyes.

Can you verify no hidden chars are present in the conf file?

Regards,

Raymond
