Cannot establish ssh tunnel aws9/27/2023 ![]() Using a VPN can "virtually move" the apparent point if your connection and can be useful for diagnosing/bypassing firewall issues. If its a simple network where you are the network admin you might want to suspect an issue with port forwarding on your router and/or bad config related to this. If its a complex network you may need to get your network administrator involved. As its Linux, running something like tcpdump -n -i any src or dst Ĭan be useful where is your external IP and where your monitoring us taking place from a computer not on the same man as your desktop.(maybe SSH to an intermediate server ie using a cellular connection or vpn?) If that does not solve it, break out traffic sniffers - seeing if the server receives and sends traffic is a useful hint. As the problem seems limited to your laptop/desktop, checking the local firewall and AV software is a good place to start. The first thing I do is examine firewall rules to check they are allowing SSH through. ![]() This also explains why you get this error on ports that SSH is not listening on. When you get connection timed out errors it means that the problem is that the SSH client is not seeing any responses from the server (ie the TCP handshake is not completing) which almost always means the problems is not with SSH, rather its at a lower level. There are a number of reasons this could be happening - these are likely due to firewalling going on somewhere. Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 23ms, Maximum = 74ms, Average = 36ms I can ping external servers fine: Pinging 1.1.1.1 with 32 bytes of data: What is causing this problem, and what do I need to do to fix it, so that I can ssh to external servers from my windows 10 computer? ssh and make sure it is owned by the user and has permissions restricted to 700. debug1: connect to address 93.184.216.34 port 2200: Connection timed out ssh: connect to host port 2200: Connection timed out In the users home directory create the folder.

My linux machine can connect to external servers (like AWS) via ssh, it's just my windows machine, and just public IP addresses, so far as I can tell. I can connect to my own linux machine from windows with a private ip address, and my windows machine connects to github with ssh public/private key authentication. Whenever I try to ssh to a public ip address from my windows 10 computer, I get an error that looks like ssh: connect to port 22: Connection timed out. I've used it before, but never had to deal much with setting it up or navigating the details. Obviously this is not the expected output.First of all, I'm pretty new to SSH.
