  1. Hello there, If you are the guy who is living in terminal like me, then I assume that you will love this script If you usually SSH-ing to servers, then I believe you used to have headache when you are trying to keep your SSH sessions alive. Most of them can resolve by adding this to your ~/.ssh/config Host * ServerAliveInterval 60 But if you are working in a company or you are connecting to Interet through VPN/Proxy, then your SSH sessions are really unstable. Like this: Write failed: broken pipe packet_write_wait connection to: XXXXX To use this script, you can download the attach file below and move it to /usr/local/bin or /usr/bin or ~/bin or just simple put it anywhere you want. I assume that you will put it into /usr/local/bin, then you can use autossh command globally. USAGE It's simple, you can just run autossh alone or with parameters autossh your_user@your_server_ip Below is the whole script #!/bin/bash # ------------------------------------------------------------------------------ # FILE: autossh # DESCRIPTION: This is an SSH-D proxy with auto-reconnect on disconnect # AUTHOR: Hector Nguyen (hectornguyen at octopius dot com) # VERSION: 1.0.0 # ------------------------------------------------------------------------------ VERSION="1.0.0" GITHUB="https://github.com/hectornguyen/autossh" AUTHOR="Hector Nguyen" SCRIPT=${0##*/} IFS=$'\n' ALIVE=0 HISTFILE="$HOME/.autossh.history" # Use colors, but only if connected to a terminal, and that terminal supports them. if which tput >/dev/null 2>&1; then ncolors=$(tput colors) fi if [ -t 1 ] && [ -n "$ncolors" ] && [ "$ncolors" -ge 8 ]; then RED="$(tput setaf 1)" GREEN="$(tput setaf 2)" YELLOW="$(tput setaf 3)" BLUE="$(tput setaf 4)" BOLD="$(tput bold)" NORMAL="$(tput sgr0)" else RED="" GREEN="" YELLOW="" BLUE="" BOLD="" NORMAL="" fi # Progress or something start_progress() { while true do echo -ne "#" sleep 1 done } quick_progress() { while true do echo -ne "#" sleep .033 done } long_progress() { while true do echo -ne "#" sleep 3 done } dot_progress() { for i in {1..100}; do printf "." $i -1 $i sleep .033 done echo_c green " 100%{$NORMAL}" sleep 1 } stop_progress() { kill $1 wait $1 2>/dev/null echo -en "\n" } # Case-insensitive for regex matching shopt -s nocasematch # Prepare history mode set -i history -c history -r # Input method get_input() { read -e -p "${BLUE}$1${NORMAL}" "$2" history -s "${!2}" } # Echo in bold echo_b() { if [ "$1" = "-e" ]; then echo -e "${BOLD}$2${NORMAL}" else echo "${BOLD}$1${NORMAL}" fi } # Echo in colour echo_c() { case "$1" in red | r | -red | -r | --red | --r ) echo "${RED}$2${NORMAL}" ;; green | g | -green | -g | --green | --g ) echo "${GREEN}$2${NORMAL}" ;; blue | b | -blue | -b | --blue | --b ) echo "${BLUE}$2${NORMAL}" ;; yellow | y | -yellow | -y | --yellow | --y ) echo "${YELLOW}$2${NORMAL}" ;; * ) echo "$(BOLD)$2$(RESET)" ;; esac } # Get data from parameters if [[ ! -n "$remote_param" && -n "$1" ]]; then remote_param="$1" remote_user="${remote_param%%@*}" remote_ip="${remote_param##*@}" fi # Get input data and save to history save_input() { if [[ ! -n "$remote_user" && ! -n "$1" ]]; then while get_input "SSH Username > " remote_user; do case ${remote_user%% *} in * ) if [ -n "$remote_user" ]; then break else continue fi ;; esac done fi if [[ ! -n "$remote_ip" && ! -n "$1" ]]; then while get_input "SSH Alias/IP-address > " remote_ip; do case ${remote_ip%% *} in * ) if [ -n "$remote_ip" ]; then break else continue fi ;; esac done fi } # Infinitie loop to keep connecting auto_connect() { while true; do exist=`ps aux | grep "$remote_user@$remote_ip" | grep 22` if test -n "$exist" then if test $ALIVE -eq 0 then echo_c yellow "I'm alive since $(date)" fi ALIVE=1 else ALIVE=0 echo_c red "I'm dead...
