Automatically passing ssh password in scripts especially to ESX where passwordless ssh is hard

Posted on by David Saliba

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 -o password_stdin

[root@ftp /mnt/test]# ntfs-3g /dev/da10s1 /mnt/test

kldload fuse

That’s a missing module needs loading.

Using ngrok with React based websites

Posted on by David Saliba

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

Nginx setting to allow wss sockets to connect

Posted on by David Saliba

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’  !!!

test :

perl -e exit

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LC_ALL = (unset),
    LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

 

Paste the following or add to server bash.rc :

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_TYPE=en_US.UTF-8

Clear Linux Cache

1. Clear PageCache only.

# sync; echo 1 > /proc/sys/vm/drop_caches

2. Clear dentries and inodes.

# sync; echo 2 > /proc/sys/vm/drop_caches

3. Clear PageCache, dentries and inodes.

# sync; echo 3 > /proc/sys/vm/drop_caches
