Automatically passing ssh password in scripts especially to ESX where passwordless ssh is hard
Posted on
First you need to install sshpass. Ubuntu/Debian: apt-get install sshpass Fedora/CentOS: yum install sshpass Arch: pacman -S sshpass Example: sshpass -p “YOUR_PASSWORD” ssh -o StrictHostKeyChecking=no YOUR_USERNAME@SOME_SITE.COM Custom port example: sshpass -p “YOUR_PASSWORD” ssh -o StrictHostKeyChecking=no YOUR_USERNAME@SOME_SITE.COM:2400 from : https://stackoverflow.com/questions/12202587/automatically-enter-ssh-password-with-script This works better for me though for sshfs: echo $mypassword | sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no user@host mountpoint -o workaround=rename…

Using ngrok with React based websites
Posted on
The problem : When we have a react.js based site (hosted on port 8000) and ngrok it for development purposes we get Invalid Host Header The fix is to override the header on reflection: ngrok http 8000 -host-header=”localhost:8000″ That’s it 😉 nJoy
Nginx setting to allow wss sockets to connect
Posted on
General idea of the config https + proxy pass + virtual host Nginx as a proxy causes a failure of wss:// connections to the backend server. add these parameters to the proxy section : proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection “upgrade”; proxy_set_header Host $host; Voila’ !!! 😉 nJoy
