To reset it to the old rsh behavior, you need:

qlogin_command               /usr/bin/telnet
qlogin_daemon                /usr/sbin/in.telnetd
rlogin_command               /usr/sge/utilbin/lx24-x86/rlogin
rlogin_daemon                /usr/sbin/in.rlogind
rsh_command                  /usr/sge/utilbin/lx24-x86/rsh
rsh_daemon                   /usr/sge/utilbin/lx24-x86/rshd -l

Adjust lx24-x86 with your type of machine. Note:
