CODE BLOCK: SecureCRT Logon Scripts = Linux

Each week I aim to review a block of code, make improvements and present it to you here.

This week I’m reviewing my own SecureCRT Logon Script for Linux.

Please refer to my main article for information on these Logon scripts, such as installation, usage, and downloads:

Guide to Setting Up SecureCRT Logon Scripts-Here Are Mine! – 1System

This week I’ve built a Ubuntu 21.04 Virtual Machine for testing SSH access profiles in SecureCRT.

Below are the improved Linux scripts.

Summary of the My Scripts!

I have 3 scripts for each type of device I connect to.

Script 1: “Connect” – Session connects, runs basic status information, and presents the logon prompt
Script 2: “Backup” – cfg_backup – Session connects, runs basic status information, completes backup, collect routing, logoff
Script 3: “Custom” – save_cmds – Session connects, runs basic status information=>Run pre-configured command blocks-Backup, show tech, server operational status, etc=>Logoff

See them all below!

For this command “top -1 -b -n1 |head -10”, I removed the “-1”. This displays each cpu’s details in Ubuntu (and most Linux’s I’ve used). In Redhat Linux, this doesn’t work, so the command errors. For a quick summary, this is probably excessive anyway.
