I have SSH access to a web server that is hosting an application on port 8080. I have a SSH session setup and a proxy configured on Chrome to redirect requests to SSH tunnel. I basically configured it using these instructions: http://drewsymo.com/2013/11/ssh-tunnel-in-30-seconds-mac-osx-linux/
I can confirm using Whats My IP that my IP is that of the SSH session and that is working correctly.
But I cannot figure out how to access the local application on the web server that I am SSHed into. When I try localhost:8080 the SSH session gives me an error "channel X: open failed: connect failed: Connection refused"
Any idea what is going on?
You can just create a port-specific tunnel:
ssh -L18080:localhost:8080 username#theothermachine
and then go to localhost:18080 on your local machine. The tunnel will forward your request to port 8080 of the localhost on the other end (and of course, localhost on the other end is the other machine itself). If that doesn't work for some reason, then replace localhost by 127.0.0.1 in the ssh command.

I want connect to my other computer with remote desktop connection but i need a problem.
I did setup ngrok and launched it and tried connect it but it doesn't connect.
This is what i did:
Setup and launched ngrok as:
ngrok tcp 5555
and i switched my own laptop and launched remote desktop connection and did that:
But it doesn't connect :(
Note: I allowed Remote Desktop Connection in control panel.
Did i miss something or how to do it correctly?
You have wrong port number for your remote desktop connection. You have to use default RDP port 3389.
Setup and launched ngrok as:
ngrok tcp 3389
I can connect my docker postgresql in my local server windows via ip or localhost. When I try to connect it remotely from my personal windows I have timeout error. Thinking about 5432 port is blocked or not listening.
I have changed pg_hba.conf & postgresql.conf files for remote connection and also checked for firewall but it was disabled.
Answer is I should have checked my server's firewall conf also, just dockerVM is not enough :)
I am trying to access my Linux machine from anywhere in the world. I have tried originally port forwarding and then ssh'ing in; however, I believe my school's WiFi won't allow port forwarding (every time I ran it, it would tell me connection refused). I have setup an account with ngrok and I can remotely SSH in, but now I am wondering if it is possible to RDP. I tried connecting via the Microsoft Remote Desktop app on Mac, but it instantly crashes. I have also looked at trying to connect with localhost, but it's not working. So far, I have tried (with xxxx being the port):
ssh -L xxxx:localhost:xxxx 0.tcp.ngrok.io
and
ssh -L xxxx:localhost:xxxx <user>#0.tcp.ngrok.io
but my computer won't allow it and after about 2 or 3 times, it warns me of a possible DNS Spoofing. Is there anyway that I can run a remote desktop of my linux machine that I have ssh tunneled to (from my mac) on ngrok? Thank you!
First you'll need to sign up with ngrok if you haven't already and you'll be given an authtoken. You'll need to install this by running
./ngrok authtoken <insert your token here>
This will save your token to a file located ../username/.ngrok/ngrok.yml
Then you'll need to ask ngrok to create a TCP tunnel from their servers to your local machine's Remote Desktop port which should be 3389 by default
ngrok tcp 3389
Give it 30 seconds or so then jump to http://localhost:4040/status to see what the tcp address ngrok has allocated you. It should look something like tcp://1.tcp.ngrok.io:158764
Now you should be able to remote into your machine using address 1.tcp.ngrok.io:158764
Host Machine - Win 7
Guest - Fedora
I have installed nginx web server on guest fedora machine and I can access the webpage inside guest machine using the interface address. How can I access the web page from host machine's browser ?
I am using bridged connection.
Router is assigning 192.168.0.16 to the guest machine's interface. I tried same address in my host machine but it doesn't work.
Based on your description:
First you should check your web application's config. You don't mention which type of your web application running on your Apache server, some are launched with the specific ip argment 127.0.0.1( or localhost), so kind of these web application can only be visited on your localhost computer. You should change the ip argument to 0.0.0.0
Second if the "Fisrt" failed, check the connection of the two server(host and your guest) by using telnet.
On your Win7, you can use the command:
telnet ip port
for example:
telnet 192.168.0.16 80
80 is the default port of Apache Http(s) Server.
if the command don't show the "connection refused" error, your Apache server is goood, so it might be something wrong of your web application.
If that, show me your error msg then we go on further.
I will try to connect I logged on locally (127.0.0.1) on Putty. Then I try to connect through the tunnel to the remote server.
I get a "Relay access denied" error. How can I solve it?
To get an SSH tunnel established:
In PuTTY, on the configuration screen go to Connection > SSH > Tunnels. Set the source port to something like 2500, which is actually localhost:2500. Set Destination to mailserver.example.com:25 (SMTP port) for whatever is the hostname of your mail server.
Connect over SSH, and you have now established a tunnel to port 25 on the destination host.
On your local machine, telnet to your local port, and you are now talking to port 25 on the remote machine.
telnet localhost 2500
