Yes Brayan I did the whole process again and looked into Target filesystem /etc/ssh. I can see the banner file with my content is there /etc/ssh/banner
Then I see the /etc/ssh/sshd-config with Banner variable to set to /etc/ssh/sshd-config But still, when I do ssh IP_address, I did not see any Banner message . I restarted the sshd service without any luck I have connected to board using putty on serial line /dev/ttyUSB1 . What could be the problem here??
