Tunneling

Script de création/suppression auto de tunnels

Ce script est a l'origine destiné a Bacula.

Pour rajouter un host, il suffit de modifier la ligne "HOSTS=...". Le port a utiliser s'incremente tout seul, en partant de 9110.

#!/bin/bash

HOSTS=host1 host2

# Stop all tunnels
TUNNEL_COUNT=$(ps ax|grep ssh|grep bacula-tun|awk '{print $1}'|wc -l)

if [ ! $TUNNEL_COUNT == "0" ]; then
  kill $(ps ax|grep ssh|grep bacula-tun|awk '{print $1}')
fi

PORT=1000
for H in $HOSTS; do
  echo $H:$PORT
  autossh -M0 -f -N -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -L $PORT:localhost:9102 -R 9103:si0-2.gre.winsoft.fr:9103 bacula-tun@$H &
  let PORT=$PORT+1
done

Proxy Socks

Create Socks Proxy:

ssh -D 9999 eadam@x.x.x.x

Config to connect to some host automatically through the socks proxy:

$ cat .ssh/config

Host 192.168.96.*
  ProxyCommand='connect -5 -S localhost:9999 %h %p'

You may need to install connect-proxy.
