Yes, it’s possible. E.g. on Linux, run ssh -N -Llocalport:dbserver:dbport yourname@connectionserver where localport is the port on your machine which will be forwarded (can be 1521 if there is no local instance of oracle running) dbserver is the name or IP of the database server dbport is the port of the database (usually 1521) yourname … Read more
The classic answer to this issue is to use 127.0.0.1 or the IP of the host or the host name instead of the “special name” localhost. From the documentation: […] connections on Unix to localhost are made using a Unix socket file by default And later: On Unix, MySQL programs treat the host name localhost … Read more
At work we usually create ssh tunnels forwarding ports. The way we do that is, by using the standard command ssh -L port:addr:port addr with subprocess running in a separate thread. I found this useful link: https://github.com/paramiko/paramiko/blob/master/demos/forward.py with an example of doing port forwarding with paramiko.
The Short Answer (TL;DR) The Remote (i.e. the localtunnel software on your computer) initializes the connection to the Relay (i.e. localtunnel.me) acts as a multiplexing proxy and when Clients (i.e. web browsers) connect, the relay multiplexes the connections between remotes and clients by appending special headers with network information.

After a bit of research here is working code. Libraries: 1) https://socket.io/ This library is used for transmit package from client to server. 2) https://github.com/staltz/xstream This library is used for terminal view. 3) https://github.com/mscdex/ssh2 This is the main library which is used for establishing a connection with your remote server. Step 1: Install Library 3 … Read more
Not as far as I know. The trick I used when I needed to do something similar was: setup a virtual interface for each Kafka broker open a tunnel to each broker so that broker n is bound to virtual interface n configure your /etc/hosts file so that the advertised hostname of broker n is … Read more
With the PuTTY suite, you can set up a tunnel either using the PuTTY itself (GUI) or using the command-line tool plink.exe. With the plink.exe, you use the same arguments as with the OpenSSH ssh, except for the -f, which does not have an equivalent in Windows. plink.exe -N -L 2000:SomeIp:2000 myusername@myLinuxBox Reference: Using the … Read more
Yes, you can. Having now gone down this path: yes, it is possible to set up an SSH tunnel from heroku to an external database. [NOTE: My particular app was written in Ruby on Rails, but the solution given here should work for any language hosted on Heroku.] Statement of the problem I am running … Read more
You can use port forwarding on ssh. 1. Open a terminal and run: On your local system: ssh -L 6000:<target_server_ip>:22 <proxy_server_user>@<proxy_server_ip> You should be connected to the proxy now. You can substitute 6000 with any port. 2. (optional) Test Now you can ssh into the target server on another terminal with: ssh -p 6000 <target_server_user>@localhost … Read more
Try this one-liner: rsync -av -e “ssh -A root@proxy ssh” ./src root@target:/dst
