Putty may be a broadly utilized, free, apparatus to SSH/Telnet/Console/etc into a arrange gadget. I can’t review how numerous times I’ve burned myself because I fat-fingered the console and after that misplaced my association to the network device or misconfigured an interface and not realize it for one or two of days. Or what in the event that you needed to keep in mind what you did a handful of months back on a switch?
Then on the left pane, click on Logging under Session.
Under the Session Logging section, select “All session output”
For the log file name, use this structure: &H-&Y&M&D-&T.log
&H – This will append the hostname of the device to the front of the file.
&Y&M&D – This adds the year, month, and day.
&T – This adds the time you logged into the device.
Click on browse to save it to a specific location. Log file will then look like: 192.168.1.1-20131024-075505.log
Go back to the Session window, click on Default Settings, and click Save. So next time you open Putty or create a new saved session, it will create the log file.
