Saya mencoba banyak solusi seperti SSH tunnel manager, tetapi semua tidak nyaman bagi saya: terlalu banyak layar konfigurasi, terkadang buggy (satu kali SSH tunnel manager membersihkan semua! Pengaturan yang saya miliki! Jadi saya harus mengembalikan pengaturan untuk semua 30 terowongan). Jadi mereka semua kehilangan kepercayaan saya. Itu sebabnya saya membuat skrip Powershell khusus, mudah dikonfigurasi, dapat diubah, kecil, tetapi berfungsi. Diposting di sini dan di bawah ini:
Untuk mulai menggunakannya, Anda memerlukan konfigurasi seperti ini:
# LocalPort TargetHost TargetPort SshHost SshUsername SshKeyPath
18080 google.com 80 bastion.example.com User D:\secure\path\to\private_key.ppk
Simpan sebagai config.csv. Dan menggunakan skrip PowerShell untuk mempertahankannya adalah:
<#
.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/

Setelah dikonfigurasi jalankan saja seperti:
powershell -File autossh.ps1
