मैंने एसएसएच सुरंग प्रबंधकों की तरह कई समाधानों की कोशिश की, लेकिन सभी मेरे लिए अनिश्चित थे: बहुत सारे कॉन्फ़िगरेशन स्क्रीन, कभी-कभी छोटी गाड़ी (एक बार एसएसएच सुरंग प्रबंधक ने सभी को शुद्ध कर दिया था! मेरे पास सभी 30 सुरंगों के लिए सेटिंग्स को पुनर्स्थापित करना था)। इसलिए वे सभी मेरा विश्वास खो बैठे। इसलिए मैं कस्टम पॉवरशेल स्क्रिप्ट, आसान विन्यास, परिवर्तनशील, छोटे, लेकिन काम करता हूं। यहाँ और नीचे पोस्ट किया गया :
इसका उपयोग शुरू करने के लिए आपको एक विन्यास की आवश्यकता है:
# LocalPort TargetHost TargetPort SshHost SshUsername SshKeyPath
18080 google.com 80 bastion.example.com User D:\secure\path\to\private_key.ppk
इसे config.csv के रूप में सहेजें। और इसे रखने के लिए एक पॉवरशेल स्क्रिप्ट का उपयोग करें:

इसे कॉन्फ़िगर करने के बाद इसे ऐसे ही चलाएं:
