rlogin questions (Unix Tip 3426 - June 26, 2012)

In the following Unix Tip from Unix Guru Universe, are there some typos?

Specifically, should:

"From hosts(user:deepak)" be "From host2(user:deepak)"? (I'm almost 100% certain it should)

"rlogin hosts.domain.com -l paul" be "rlogin host2.domain.com -l paul"?

Some related questions (to one thing or another):

is there any better place to ask questions about these Unix Tips of the Day?
can anyone suggest some very simple ways to learn about rlogin, rsh, telnet, ssh and such? I seem to get easily confused, and I'd like to find some simple "bite sized" sources of information with sketches that would help me learn this stuff once and for all.

Thank you!

Unix Tip 3426 - June 26, 2012

AUTOMATIC LOGIN TO REMOTE HOSTS

Consider two hosts.
host1.domain.com
host2.domain.com

>From hosts(user:deepak), 
you wish to logon to
host1(user:paul).

Paul would create a .rhosts 
file in his directory 

chmod 744 .rhosts 

(No write permission for 
others) The first line 
would contain 
host1.domain.com deepak

Now, deepak should be able 
to logon to host2.domain.com 
as user paul by using rlogin.

Deepak will type
e.g
rlogin hosts.domain.com -l paul

And he should be in.

ypset

ypset(8)						      System Manager's Manual							  ypset(8)

NAME

       ypset - bind ypbind to a particular NIS server

SYNOPSYS

       ypset [ -d domain ] [ -h hostname ] server

DESCRIPTION

       In   order  to run ypset, ypbind must be initiated with the -ypset or -ypsetme options.	See ypbind(8).	ypset tells ypbind to get NIS ser-
       vices for the specified domain from the ypserv(8) process running on server.

       In cases where several hosts on the local net are supplying NIS services, it is possible for ypbind to rebind to another  host  even  while
       you attempt to find out if the ypset operation succeeded. For example, you can type:

       example% ypset host1
       example% ypwhich
       host2
       which  can  be confusing. This is a function of the NIS subsystem's attempt to know always a running NIS server, and occurs when host1 does
       not respond to ypbind because it is not running ypserv (or is overloaded), and host2, running ypserv, gets the binding.
       Server indicates the NIS server to bind to,  and must be specified as a name or an IP address. This will work only if the node has  a  cur-
       rent  valid  binding for the domain in question, and ypbind has been set to allow use of ypset.	In most  cases, server should be specified
       as an IP address.
OPTIONS

       -d domain
	      Specify a domain other than the default domain as returned by domainname(1).
       -h hostname
	      Set the NIS binding on host hostname
	       instead of the local machine.
