Linux Port Scanning
Check what services are running on the Linux system using port scanning utilities.
These commands are sometimes used to identify open TCP ports and related services:
# netstat -tulp
# lsof -iTCP -sTCP:LISTEN
# nmap -sTU
Fixed WSL sshd: no hostkeys available -- exiting
Encountered: $ sudo service ssh --full-restart * Stopping OpenBSD Secure Shell server sshd [ OK ] * Starting OpenBSD Secure Shell server sshd sshd: no hostkeys available -- exiting. Run ssh-keygen -A In the /etc/ssh/ folder, and then restart the server by: $ sudo service ssh --full-restart * Stopping OpenBSD Secure Shell server sshd [ OK ] * Starting OpenBSD Secure Shell server sshd [ OK ]
