How to Showtime and Utilize Putty SSH Client
When nosotros launch putty, yous will see a dialog box that controls everything that we can do with putty. Configuring sessions and related parameters are pretty easy in putty through this dialog box.
Permit us now explore some important options from the dialog box.
Remote Server Connectedness
To connect to any remote servers via SSH we will use either IP accost or FQDN (Fully qualified domain proper noun). By default, SSH is bonded to port 22 unless the SSH port was changed.
In that location are four connection types bachelor RAW, Telnet, Rlogin, SSH, Serial. Most of the fourth dimension nosotros volition use either Telnet or SSH connection.
Nosotros can as well configure our sessions and save them. This allows u.s.a. to reopen our session with all the configurations retained.
You will get an alert as displayed in the below image either when you connect with the server for the first fourth dimension or when the SSH protocol version is upgraded. Putty registers the server'southward host fundamental in the Windows registry and then it can verify against the fundamental whenever nosotros log in to the server and throws a alarm in instance of a alter in the host key. This is one of the features of the SSH protocol to prevent whatever network attack.

To utilise this feature, nosotros need to select the checkbox "Motorcar wrap manner initially on". If Wrap Mode is set to off will it create a horizontal scrollbar? well, no. It simply will non display the lines that are greater than the length of the folio.
NOTE: This setting tin can too be inverse in the middle of an established session which will be taken into immediate effect.
Increase Window Scroll Buffer Size
At that place is a limitation on how many lines of text putty keeps. When you are working with very large files or trying to display log files putty merely keeps a few lines of it in windows buffer for us to scroll back and see. To increase the scrollback buffer size, nosotros can increase the value "Lines of scrollback".
You lot can also change some behaviors when the window is resized like irresolute the size of the font.
Enable SSH Keep Alive Fourth dimension
In that location might be situations where y'all will come across 'Connection reset by peer' error because of our session is idle for a long fourth dimension. In such a case, the connection will be closed by the network devices or firewalls assuming the session is completed.
Nosotros tin set keepalives so null packets will exist sent to prevent connection drib. Values mentioned in Keepalives are measured in Seconds. Keepalives are supported only in Telnet and SSH.
Enable Auto SSH Login with Username
Whenever you connect to a session information technology volition prompt with username and countersign. Instead of typing username every time you can set the user name under Login details.
Y'all can also configure your session for password-less login using SSH (Public & Private) cardinal hallmark. To know more nigh generating and configuring countersign-less login take a look at this article.

Yous tin alter the colour scheme and appearance of the putty terminal. At that place are some nice collections of colour schemes for putty in GitHub.
Change the advent like font, font size, cursor appearance, etc.

- If the log file already exists in the given path and so we can either overwrite or append the logs.
- Date and Time options are available to format the log file proper name which is very handy.
Now I tried connecting to a remote machine that is running Linux Mint 19 and storing the output locally. Any I type in my terminal, its output is captured in session logs.
There might be times where we might need to connect to multiple sessions or restart the current session or indistinguishable the current session. Right-click from the putty title bar where we accept options to commencement/restart/duplicate sessions. We can also change the settings for the current session from the "Modify Settings…" option.
Putty Telnet Session
Telnet connection can be established when nosotros utilize connectedness type equally "Telnet". By default, port 23 is taken, different ports can as well be used to check if ports are opened or non.
