How do I configure a console server under OpenBSD. Want to access via ssh on the console server to access the serial port from everywhere in the world. Want to use only OpenBSD, so the console server should run under OpenBSD. Thank you very much
http://openports.se/comms/conserver should provide the funtionality you need. SSH to host and access the serial lines.
Description: This program provides a convenient way to manage many remote serial consoles for machines. A server (conserver(1)) runs on each server machine and it connects to the specified serial port. It can log, provide shared access to remote consoles, etc
Not sure I understand the question very well, but you can simply connect via SSH and then use the built-in serial terminal emulator, cu(1), to access the serial port. See the man page for details.
