We have various customers that have firewalls that only allow known trusted IP addresses through. Normally our office and our monitoring platform for example.<\/p>\n
But if we are out and about we still sometimes need to access a system and its GUI, so we have created the simple script below that makes a ssh connection to the customer server and also tunnel to access any web gui.<\/p>\n
This script is in place on the monitoring server so we can just ssh in to the monitoring platform and run the script. all that is needed is a single tunnel setup on the ssh client that i’m accessing the monitoring platform from.<\/p>\n
