Description Christian Castens univentionstaff 2021-07-14 09:33:19 CEST
+++ This bug was initially created as a clone of Bug #50620 +++

Situation: Internal DNS does not resolve external addresses. Access to internet only works through http-proxy.

Running the diagnostic checks fails:

univention-run-diagnostic-checks --username Administrator --bindpwdfile <(echo -n univention) -t 11_nameserver
  timeout resolving 'www.univention.de' with NS X.X.X.X

univention-run-diagnostic-checks --username Administrator --bindpwdfile <(echo -n univention) -t 12_proxy
  Failed writing body (0 != 8088) (code=23)

univention-run-diagnostic-checks --username Administrator --bindpwdfile <(echo -n univention) -t 23_check_update_sites
  {updates,appcenter}.software-univention.de are not resolvable
  The PROXY server does that, the host itself does not need to be able to resolve the host

The System Diagnostic check no longer shows false positives when a http-proxy is set.
