[GeoNode-users] Get Remote Service (harvest CSW); add external WMS to Base Maps list

Hello,
I did not get any answers to my questions below. Is something unclear? Are those uncommon issues?
Questions:
[1] Get remote Services – harvest a CSW
[2] ArcGIS WMS as Base Map in GeoNode

[1] Get remote Services – harvest a CSW:

I have changed my
Local_settings.py to switch to our GeoNetwork instance which is on a different machine (Windwos Server with ArcGIS Server) since I thought GeoNode would load the data which is stored in there (but it does not):

CATALOGUE = {
    'default': {
        # The underlying CSW backend
        # ("pycsw_http", "pycsw_local", "geonetwork", "deegree")
        #'ENGINE': 'geonode.catalogue.backends.pycsw_local',
        # The FULLY QUALIFIED base url to the CSW instance for this GeoNode
        #'URL': '%scatalogue/csw' % SITEURL,

        # GeoNetwork opensource
        'ENGINE': 'geonode.catalogue.backends.geonetwork',
        'URL': 'http://gissrv.aes.hs-owl.de:8080/geonetwork/srv/en/csw',
        'USER': 'admin',
        'PASSWORD': 'AwesomePassword',

    }
}

I have added some entries to ALLOWED_HOSTS,  but am not quite shure if these are correct:

# For more information on available settings please consult the Django docs at
# https://docs.djangoproject.com/en/dev/ref/settings

ALLOWED_HOSTS=['localhost', 'geonode.aes.hs-owl.de','.hs-owl.de','*']
PROXY_ALLOWED_HOSTS=['*', 'localhost']


Since I still am not able to harvest a REMOTE CSW with the following settings:
SERVICE URL:
http://geoportal.geodaten.niedersachsen.de/harvest/srv/ger/csw?SERVICE=CSW&VERSION=2.0.2&REQUEST=GetCapabilities

SERVICE TYPE:
Calalogue Service

[2] ArcGIS WMS as Base Map in GeoNode
I managed to achieve this by using a cascaded WMS from Geonodes Geoserver instance. I can query the geoserver and add the wms to my map as layer.
How to get it displayed in the list of basemaps?

Betreff: Re: [GeoNode-users] Implementing GeoNode for University

Geonode 2.4 beta has "remote services" feature which allows admins to register remote WMS/ESRI REST/CSW services from the admin menu... I'd suggest this for the #1 but know the limitations - https://github.com/GeoNode/geonode/issues/2064.

For #2 I'd suggest putting in a wildcard for allowed proxy while testing out in your local_settings.py file within your geonode_project:
PROXY_ALLOWED_HOSTS=['*', 'localhost']

When ready for production you'll want to enter each IP address ['192.168.1.1', '_________', 'localhost'] of the servers you'll be registering remote services from. Do you have access over these ArcGIS servers? if so I'd suggest enabling their WMS service for each resource your'e registering and setting its default projection to ESPG:3857. That way legend/getfeatureinfo/query will work for those services when registered remotely. Otherwise all you'll get from registering from ESRI REST is the map export which is essentially a tiling service.

Hello Internet,
Thanks for the variety of info about the usefullnes of Geonode for an organisation like my university!
I spent the last couple of days to install geonode on a server and am able to get to the web interface. Some things bother me though:
1. How can I harvest other CSW? I have a GeoNetwork running which does an excellent job there - is it possible to just use that as input for geonode?
2. I want to add our ArcGIS Server with its REST point to the list of servers, so the users could use the add layer button from the map view to query the datasets there. But I get this error:
>> DEBUG is set to False but the host of the path provided to the proxy service is not in the PROXY_ALLOWED_HOSTS setting
Seems like I should change some settings.
Thanks in advance
