Nipper and Cisco configuration results

I looked at the configurations yesterday on the routers.  The vty line does not have any "transport" line below it.  All the routers showing "Rlogin enabled" have similar configuration.

What are the default services that are enabled for vty on IOS 12.4?  I know there are only telnet, SSH and Rlogin.  Is there any particular sequence that IOS processes the vty access?

I played with it a bit - removing the "transport input telnet" on a
vty line got me the rlogin service is enabled.  Add it back & nipper
says it's disabled...

Do you have a "transport input telnet" on each vty?  If not, does
adding it fix the nipper report?
