Ich habe viele Lösungen wie SSH-Tunnelmanager ausprobiert, aber alle waren für mich unpraktisch: Zu viele Konfigurationsbildschirme, manchmal fehlerhaft (einmal löschte der SSH-Tunnelmanager alle! Einstellungen, die ich hatte! Also musste ich die Einstellungen für alle 30 Tunnel wiederherstellen). Also haben sie alle mein Vertrauen verloren. Aus diesem Grund habe ich mir ein benutzerdefiniertes Powershell-Skript ausgedacht, das einfach konfigurierbar, änderbar und klein ist, aber funktioniert. Hier und unten gepostet :
Um es zu benutzen, brauchst du eine Konfiguration wie diese:
# LocalPort TargetHost TargetPort SshHost SshUsername SshKeyPath
18080 google.com 80 bastion.example.com User D:\secure\path\to\private_key.ppk
Speichern Sie es als config.csv. Und verwenden Sie ein Powershell-Skript, um es auf dem neuesten Stand zu halten:

.SYNOPSIS
Powershell script for keeping ssh tunnel up and running
.DESCRIPTION
This script uses configuration of tunnels located in config.csv. For more information visit http://tsherlock.tech/2019/03/13/simple-ssh-tunnel-auto-reconnect-using-putty-and-powershell/

Nachdem es konfiguriert ist, führen Sie es einfach wie folgt aus:
