SSH

Local port forwarding

To forward port of remote host use the following command

ssh -L <LOCAL_PORT>:<TUNNEL_IP>:<DESTINATION_PORT> <user>@<server_ip>

-L stands for local adress because we are tunneling connection on local machine, TUNNEL_IP is 127.0.0.1

ssh -L <LOCAL_PORT>:127.0.0.1:<DESTINATION_PORT> <user>@<server_ip>

I have a server with ip 69.69.69.69
I have user on a server called gnumik
My public key is recognized by this server and I can establish ssh connection like this:

ssh gnumik@69.69.69.69

I have postgresql data base running on the server on port 5432
I want to have access to this postgre instance from my local machine using local port 5433
I need to execute the following command on my local machine:

ssh -L 5433:127.0.0.1:5432 gnumik@69.69.69.69

P.S. I use arch btw

Скачать с сервера

scp -r -P 22 -i ~/.ssh/privkey user@192.168.1.7:/home/myuser/from "C:\localfolder"

Залить на сервер

scp -r -P 22 -i ~/.ssh/privkey "C:\localfolder" user@192.168.1.7:/home/myuser/to

В случае если нужно передать только один файл, уберите опцию -r

ssh-сервер в качестве прокси для браузера

ssh -i ~/.ssh/privkey -p 22 myuser@192.168.1.7 -D 2141 -N

start chrome --proxy-server="socks5://localhost:2141"
