From a terminal, navigate to the folder where you saved the private key file
And Run this command:
chmod 400 my-key-pair.pem
(Replace my-key-pair.pem with your key file name)

To connect to your instance using SSH
From a terminal window, navigate to your key pair folder
and run the ssh command:

ssh -i my-key-pair.pem my-instance-user-name@my-instance-public-dns-name


Commands to Install telnet and connect to your ElastiCache Memcached Cluster:
From a terminal or windows PowerShell:
sudo yum install telnet -y
telnet mycachecluster.eaogs8.0001.usw2.cache.amazonaws.com 11211
telnet Memcached commands to test your ElastiCache Memcached Cluster:

set key1 0 0 5 // Set key "key1" with no expiration and 5-byte value
hello // Set value as "hello"
STORED
get key1 // Get value for key "key1"
VALUE a 0 5
hello
END
get key2 // Get value for key "key2" results in miss
END
set key2 0 0 5 // Set key "key2" with no expiration and 5-byte value
hello // Set value as "hello"
replace key2 0 0 11 // Replace key "key2" with no expiration and 11-byte value
Hello World // Set value as "Hello World"
get key2 // Get value for key "key2"
Hello World
END
delete key1 // Delete "key1"
get key1 // Get value for key "key1" results in miss
END
