There is no rc.d script provided under OpenBSD for sshd service. How do I restart OpenSSH sshd server without rebooting OpenBSD 4.x server?
You need to send HUP single to OpenSSH SSHD server using kill command. The default pid file is located at /var/run/sshd.pid:
# cat /var/run/sshd.pid
Send HUP single to sshd PID # 5367:
# kill -HUP 5367
This can be done with a single command as follows:
# kill -HUP `cat /var/run/sshd.pid`
