try using one of the accounts that have a shell correctly entered.
if you can access this account, you can then take over root (even if root
doesn't have a shell defined).

-~->Nope.  See I recompile bash and though I copied it over to
-~->/usr/local/bin (I
-~->guess I didn't) and then did a vi /etc/passwd and changed all
-~->the account
-~->(except root) to point to the 'new' bash.  Either it didn't
-~->copy over right
-~->(or I copied it to the wrong place) or I missed typed all the shells for
-~->those accounts.  The only account at this point is root.  I do have 'r'
-~->access to a couple programs like rsh and rlogin, but they don't
-~->like working
-~->to well without a shell.
-~->
-~->I tried doing a
-~->
-~->/bin/rsh host.domain.com /bin/sh
-~->
-~->but it gave a permission denied.  If I do a /bin/rsh
-~->host.domain.com it asks
-~->for a password, then fails with a "no shell" error message.
