I have tried to set up an OpenVPN client under docker, using the dperson/openvpn-client image. I get the following error:
UDPv6: Address not available (code=99)
When googling this problem, I've come across this discussion, but I'm not sure how to look at the client and server logs separately.
I'have the full logs on pastebin here
I am able to get the IP of my home address inside the container, but not the IP from the VPN. I appreciate any help
!
The problem here is that the TLS handshake fails.
I extracted this from your logs:
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
TLS Error: TLS handshake failed
Make sure your server is setup correctly.

When enabling https on CapRover got the following error:

Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
Error message pointed to the right issue - firewall problem
After configuring firewall to open port 80 the problem got resolved.

i've changed nothing within my setup and ngrok seems to have stopped working for me.
Running ngrok http -host-header=rewrite launch.localhost:80 would usually work just fine.
This is my error:
The connection to http://d678207f86ae.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address launch.localhost:80.
Make sure that a web service is running on launch.localhost:80 and that it is a valid address.
The error encountered was: dial tcp: lookup launch.localhost: no such host
If I navigate to launch.localhost the docker server is running just fine.
Not too sure what kind of other information you'd need to help?
For me, it was never running before, but I was getting the same error for
ngrok http -host-header=rewrite launch.local:80
It helped when I changed it to
ngrok http -host-header=launch.local 80
I setup a guacamole server on ubuntu 16.04 Tried to setup a connection to a vnc server on the same machine and always got errors. I tried with RealVNC Xvnc11 TIghtVNC, and even with RDP. no luck. The error messages on log files were:
Creation of WebSocket tunnel to guacd failed: Non-numeric character in element length.
Creation of WebSocket tunnel to guacd failed: java.net.ConnectException:
Connection refused (Connection refused)
An internal error has occurred within the Guacamole server
not a valid RFB client
webSocketsHandshake: invalid client header
Any idea what could be?
The problem was that I was saving the VNC connections settings on the GUACAMOLE PROXY PARAMETERS (GUACD). I set port 5901. Which is not the correct guacd port.
I left this empty and everything worked!
for RDP use RDP encryption select option
it worked for me.
I am trying to deploy a data flow server on Cloud foundry and create a simple app.
Only https end point could be exposed. I cannot enable https using this :
http://docs.spring.io/spring-cloud-dataflow/docs/current-SNAPSHOT/reference/htmlsingle/#configuration-security-enabling-https
As ssl is managed by cf. How do I make data flow server using https?
I have this error:
dataflow:>app list
Command failed org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://dataflow-server.run.aws-usw02-pr.ice.predix.io/apps": Connect to dataflow-server.run.aws-usw02-pr.ice.predix.io:80 [dataflow-server.run.aws-usw02-pr.ice.predix.io/54.201.89.124, dataflow-server.run.aws-usw02-pr.ice.predix.io/52.88.128.224] failed: Connection refused (Connection refused); nested exception is org.apache.http.conn.HttpHostConnectException: Connect to dataflow-server.run.aws-usw02-pr.ice.predix.io:80 [dataflow-server.run.aws-usw02-pr.ice.predix.io/54.201.89.124, dataflow-server.run.aws-usw02-pr.ice.predix.io/52.88.128.224] failed: Connection refused (Connection refused)
Thanks in advance.

as you already mentioned, you can not enable https at the container level inside cloudfoundry today. The traffic between the router and diego cell is not encrypted (unless you are using IPSEC).
So your dataflow server would not be configured with https, just deploy the server as it is. You should rely on your cloudfoundry install to have an open port at 443 on it's loadbalancer that forwards traffic to the router. Later CF incarnations support certificate placement at the router level.
Now, at the client (dataflow-shell) if you are using a valid certificate you don't need to do anything, but if you have a selfsigned certificate, you need to tell it to accept self-signed certificates, or skip validation all together.
I did install Opennms in a VM Ubuntu on PROXMOX. Everything went well until I did change the interface IP address because the VM must work in a LAN without Internet access. Since then the opennms start correctly but the browser give me the error:
Jetty: HTTP ERROR: 503
Problem accessing /opennms/. Reason:
Service Unavailable
The problem seems to be related with the connection to Internet at the starting of opennms. When I start opens without Internet connection the server do to start correctly.
OpenNMS has a bugfix that may take care of it.
