IPv4 and IPv6 enabled (default)
Disable rsh for both in /etc/inetc.conf

>Description:

Misleading try/fail messages result in operator confusion

% rsh localhost
connect to address 127.0.0.1: Connection refused
Trying ::1...
connect to address 127.0.0.1: Connection refused
Trying ::1...
connect to address 127.0.0.1: Connection refused
Trying ::1...

It appears that both IPv4 and IPv6 are tried, and both fail from
connection refused.  However, the messages are different and confusing.
Should probably read:

Trying 127.0.0.1...
connect to address 127.0.0.1: Connection refused
Trying ::1...
connect to address ::1: Connection refused
...

Also, rsh now appears to retry connecting via the same medium
multiple times (6 times, in this case).  I do not believe it used to
do that, satisfying itself with one connection refused on IPv4 before
giving up.

>How-To-Repeat:

Comment out rsh stuf in inetd.conf
rsh localhost

>Fix:

None available.
