Problem with (re-)installing server

KNIME Server
1

Hello,

try to reinstall KNIME server and encounter following error

!ENTRY org.eclipse.equinox.p2.transport.ecf 4 1006 2018-10-10 12:00:05.344
!MESSAGE Unknown Host: http://update.knime.com/analytics-platform/3.6/content.xml
!STACK 0
java.net.UnknownHostException: update.knime.com

If I try to reach resource via wget

knime@myhost:~$ wget http://update.knime.com/analytics-platform/3.6/content.xml
–2018-10-10 13:16:49-- http://update.knime.com/analytics-platform/3.6/content.xml
Resolving proxy.mynet (proxy.mynet)… 10.216.249.124
Connecting to proxy.mynet (proxy.mynet)|10.216.249.124|:8080… connected.
Proxy request sent, awaiting response… 404 Not Found
2018-10-10 13:16:49 ERROR 404: Not Found.

I’m unsure if proxy blocks but the output of wget looks like content.xml is not there.
Any ideas?

Thanks,
René

Hi René,

I think the content.xml can’t be accessed via WGet. However, the actual problem is that you can’t reach update.knime.com. This might be due to a proxy-setting, firewall, etc. Did you check that?

Best,

Christian

Thanks for your answer and sorry for my delay.
Yes, my host can’t reach update.knime.com directly.
I tried installation with
export http_proxy=http:/mylocalproxy.locdomain:8080
before, but no success.
In the installation documentation and also in the forum I didn’t found any hint to installation of server behind a firewall. I can’t imagine that I’m the only one.
Thanks for any hint to setting proxy and to installation of knime server behind company firewall.

Hi @ReWi

did you already see our new documentation? docs.knime.com

For installing the server you need the KNIME Server Installer.
If you want to install it offline, you in addition need the KNIME Server Executor to be installed before the Installation of the Server.

The installer will ask you if you want to select an existing installer or automatically install one by downloading. Please chose here to use the existing one as preinstalled. You can find this here as well: https://docs.knime.com/2018-12/server_installation_guide/index.html#_knime_server_executor_configuration

The KNIME Executor comes with most extensions preinstalled. If you need anything in additon, you need to install them via a local update site. You can find the description how to use local update sites here: https://docs.knime.com/2018-12/analytics_platform_installation_guide/index.html#_adding_local_update_sites

Best wishes, Iris

Hi ReWi,

It’s also possible to use ‘zipped update sites’ as part of the executor installation section of the server installer that can be downloaded from the relevant release linked from the product downloads page.

Best,

Jon
