Description Stefan Gohmann univentionstaff 2014-09-10 08:28:56 CEST
We should add a system diagnostic plugin which checks the network setup, for example is the gateway reachable, does the DNS server and the name server answer DNS requests. If an error occurs, the module should redirect to the system setup network module.

Maybe add a test for an eventually configured http proxy too.
Comment 2 Florian Best univentionstaff 2014-10-02 11:13:20 CEST
Three plugins have been added:

pings the gateway with a maximum timeout of 500ms. Refers on failure to the Setup - Network module.

if proxy/http is configured it tries to get the content of http://univention.de via the proxy (is it OK to use that domain for testing purposes?)
It offers a button to disable the proxy server completely. → remove this?
TODO: find out a little bit more about the cause of the failure (wrong credentials, proxy down, etc.).

Tries to reach every nameserver[1-3] doing a lookup of the IP for the own hostname.
Tries to reach every dns/forwarder[1-3] doing a lookup of the IP for www.univention.de.
If the domain does not exists the test doesn't fail. Every other error fails (e.g. timeout).
Comment 3 Florian Best univentionstaff 2014-10-02 17:48:58 CEST
The texts have been adapted, some code cleanup was done, proxy.py has been enhanced to give more detailed information.
Comment 4 Stefan Gohmann univentionstaff 2014-10-19 19:52:43 CEST
Move all unfinished MS1 and MS2 bugs to RC.

notifications have been removed.
Comment 7 Felix Botner univentionstaff 2014-10-30 11:20:40 CET
FAIL - proxy with basic authentication does not work
       Why do we need a "disable proxy" button here?

OK - gateway test

OK - nameserver/dnsforwarder test
     Maybe we should add a hint that the dns/forwarder must be 
     able to resolve "www.univention.de"?

fixed, curl is able to do BASIC, DIGEST and NTLM.

> OK - nameserver/dnsforwarder test

hint added

→ Translations fixed, they were missing in the .mo file because dh_umc.py did not add subdirectories.

Package currently builds.
