#StackBounty: #networking #openvpn #vpn Why can I not connect to an OpenVPN server's LAN interface over the tunnel?

Bounty: 50

I setup OpenVPN between my work and my home. It’s using certificates (not pre-shared keys), is in tun mode, and works great. The networks look like this:

Diagram

I have proper routes setup to send traffic back and forth, and the client has no problems talking to either 192.168.80.1 (the server’s tunnel IP), or anything on the 192.168.5.0/24 (work) network, which is great.

The one problem I’m having is that the client can not talk to, or ping 192.168.5.10 (the server’s IP on the work network).

iptables isn’t blocking anything. Is there some OpenVPN security setting, or Linux setting I’m missing?

#StackBounty: #16.04 #networking #wireless #intel-wireless #iwlwifi Wifi Extremely Slow in Ubuntu 16.04 with Intel Centrino Wireless N …

Bounty: 50

After perusing through several answers here and trying them out, I’m stumped as to what’s causing the slow wifi on my laptop.

For reference, I tested the wifi on my laptop both in Windows 7 and in Ubuntu 16.04 LTS. I clocked an average down speed of ~28 Mbps on Windows and ~9 Mbps in Ubuntu.

I tried this Ask Ubuntu answer which brought my Ubuntu down speed to ~22 Mbps but my speeds go back down after the laptop comes back from sleep.

I used the wireless-info script to post my wifi information here.

Please let me know if there’s any additional information needed and I’ll get right on it. Thanks for your help.

#StackBounty: #networking #macos #vnc #realvnc Cannot connect to RealVNC on MacOS over local network (cloud works)

Bounty: 50

So I have a Mac mini which I primarily use to run builds on. I have been using its built in vnc server for about a week but it is painfully slow, and for some reason takes a good 2 minutes to initialize a connection. I figured I’d try RealVNC instead.

After initial setup I can connect through RealVNC using the cloud connection, essentially routing my connection over the internet. But both pcs are on the same network so I’d rather use a local connection. Thing is this doesn’t seem to work -at all-. No matter what I tried I keep getting connection refused.

Things I’ve tried:

  • Adding it to Accessibility apps
  • Changing the port to 5800 and 5901
  • Connecting to the same computer with SSH to see if that works (it does)
  • Turning on debug logging (nothing in there)
  • Ensuring my firewall is off (it is)

Both computers are connected to the same switch, but if that were the problem then SSH wouldn’t work either.

Anyone have any idea why this isnt working?

First VPN is created by some 3rd party VPN client. Second is built in OS X VPN connection, set to default.

The host that I am trying to connect via second vpn is in the subnet 32.169.0.0/16.

I’ve tried to add routing for that specific host, without much success

sudo route add -host 32.169.111.222 10.56.10.5 -interface utun2

What route would help me to add routing to the specific host via both tunnels? Just to be clear – utun1 is just helper tunnel for utun2.

I setup OpenVPN between my work and my home. It’s using certificates (not pre-shared keys), is in tun mode, and works great. The networks look like this:

I have proper routes setup to send traffic back and forth, and the client has no problems talking to either 192.168.80.1 (the server’s tunnel IP), or anything on the 192.168.5.0/24 (work) network, which is great.

The one problem I’m having is that the client can not talk to, or ping 192.168.5.10 (the server’s IP on the work network).

iptables isn’t blocking anything. Is there some OpenVPN security setting, or Linux setting I’m missing?
