sshd_config all parameters commented out

Question

I've inherited administration of a server (and I am not really an admin) and unfortunately there are a ton of things I've never been exposed to.

All of the parameters in the sshd_config are commented out. ssh is working fine however. Does this mean that a default configuration is being used? What is the reason that the previous admin may have done this?

Answer 1

Yes, it means default configuration is being used. There is no particular reason, which can be connected to blank sshd_config. May be previous admin was debugging some sshd issues.
