Linux server telnet to server Go tool usage

Background

Always need to log on to the online service to solve various problems, such as:
Remote Login online log machine view PHP error log, Mysql error log, etc.
Log in QA tester to check if the code is properly released and the configuration is correct
Log on to a personal development machine
But the company's servers are required to log on through the springboard, each login on the machine need to log in first to the springboard, and then login to the target machine, very cumbersome, and must remember to live the target machine IP or machine name to log on as soon as possible, or else have a meal check ...

So I got a gadget, a quick login (in fact, a little script written a few years ago, recently upgraded), and shared it with everyone. The function probably includes:
Customizing shortcut logon methods for remote machines
View all configured shortcuts
Support for two kinds of scenarios for springboard and non-springboard login
For any authorized machine, you can log in directly to a single command
Can specify any account login online server
In short, it is quite convenient, simple gadgets, open to everyone, you may also use.
