/etc/ssh/sshd_config:

PermitRootLogin no

You will have to login as ordinary user, and than do "su -".

Use tcpwrappers to limit users and IP addresses:

/etc/hosts.allow:

sshd: peter@xxx.xxx.xxx.xxx

but it works only if sshd is compiled with libwrap.so.0, or if it is 
controlled by inetd (see intetd.conf, or xinetd.conf). If you use 
standalone ssh daemon, try

ldd /usr/sbin/sshd

If there is no libwrap, you will have to compile source code with this flag:

--with-libwrap

Hope it helps.
