sshd block access from some host names

  • 772

I want to block access from some external host to my ssh deamon. Is there something in the sshd_config file I can set?

Just if this matters: I'm on a Synology 1010+ with openssh installed from ipgk, if this matters.

ssh synology

    you can do this by adding the following to your sshd_config

    DenyUsers username@host

    for example when you want to ssh acces from the 80.25 ip-range for root:

    DenyUsers [email protected].*

    From the manpages:

    The allow/deny directives are processed in the following order: DenyUsers, AllowUsers, DenyGroups, and finally AllowGroups.
