the similist way would be to find the latest openssh rpms for redhat 
( try the RH 8.0 ones and see if they install ) 

Once you have the 8.0 ( or 7.3 ) rpms installed, you can do a 
/etc/rc.d/init.d start to start it up. Also use the redhat sysystem 
startup gui to make ssh start at boot time or use the 
chkconfig command to add it to the startup list. 

As for limiting to a single user... you can compile the 
openssh to use /etc/hosts.allow / /etc/hosts.deny but I don't 
know if the redhat RPMs have that enabled. You may have to 
compile your own openssh from source and specify the tcpwrappers 
stuff. 

instead of limiting by ip address, you could make all users have
a valid ssh key and not allow plain passwords/userids. That 
would make it more secure.
