Create a group in /etc/group on each remote node - icanssh as an example
Assign those users who are allowed to ssh into the machine to that group only on that machine.
Then in /etc/ssh/sshd_config add a line:
It is just easier and safer to deny all access for those users to a given node - disable their account. Or remove shell access
by defining the shell as /bin/false
As a general, deny all access, then grant access just to those who need it - is a far safer strategy

login.access
LOGIN.ACCESS(5) BSD File Formats Manual LOGIN.ACCESS(5)NAME
login.access -- login access control table
DESCRIPTION
The login.access file specifies on which ttys or from which hosts certain users are allowed to login.
At login, the /etc/login.access file is checked for the first entry that matches a specific user/host or user/tty combination. That entry can
either allow or deny login access to that user.
Each entry have three fields separated by colon:
o The first field indicates the permission given if the entry matches. It can be either ``+'' (allow access) or ``-'' (deny access) .
o The second field is a comma separated list of users or groups for which the current entry applies. NIS netgroups can used (if configured)
if preceeded by @. The magic string ALL matches all users. A group will match if the user is a member of that group, or it is the user's
primary group.
o The third field is a list of ttys, or network names. A network name can be either a hostname, a domain (indicated by a starting period),
or a netgroup. As with the user list, ALL matches anything. LOCAL matches a string not containing a period.
If the string EXCEPT is found in either the user or from list, the rest of the list are exceptions to the list before EXCEPT.
BUGS
If there's a user and a group with the same name, there is no way to make the group match if the user also matches.
