RSH bisa dibaca di wikipedia. sebenarnya case RSH tidak aman, maka sampe sekarang SSH masih powerfull untuk dipakai. Berikut dokumentasi nya:
Autologin dengan RSH.
0. Cek paket
[root@eptcproc5 ~]# rpm -qa | grep rsh rsh-0.17-40.el5 rsh-server-0.17-40.el5 [root@eptcproc5 ~]#
1. vim /etc/hosts.equiv
[root@eptcproc5 ~]# cat /etc/hosts.equiv eptcproc1 eptcproc2 eptcproc3 eptcproc4 eptcproc5 eptcproc6 eptcproc7 eptcproc8 eptcproc9 eptcprocdb eptcomega1 eptcomega2 eptcomega3 eptcomega4 eptcomega5 eptcomega6 eptcomega7 eptcomega8 eptcomega9 eptcomega10
2. vim /etc/hosts
[root@eptcproc5 ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 eptcproc5 localhost.localdomain localhost 192.168.2.11 eptcproc1 192.168.2.12 eptcproc2 192.168.2.13 eptcproc3 192.168.2.14 eptcproc4 192.168.2.15 eptcproc5 192.168.2.16 eptcproc6 192.168.2.17 eptcproc7 192.168.2.18 eptcproc8 192.168.2.19 eptcproc9 192.168.2.20 eptcprocdb 192.168.2.22 eptcomega2 eptcomega2.omega 192.168.2.23 eptcomega3 eptcomega3.omega 192.168.2.24 eptcomega4 eptcomega4.omega 192.168.2.25 eptcomega5 eptcomega5.omega 192.168.2.26 eptcomega6 eptcomega6.omega 192.168.2.27 eptcomega7 eptcomega7.omega 192.168.2.28 eptcomega8 eptcomega8.omega 192.168.2.29 eptcomega9 eptcomega9.omega 192.168.2.21 eptcomega1 eptcomega1.omega 192.168.2.30 eptcomega10 eptcomega10.omega
3. vim /etc/securetty
[root@eptcproc5 ~]# cat /etc/securetty console vc/1 vc/2 vc/3 vc/4 vc/5 vc/6 vc/7 vc/8 vc/9 vc/10 vc/11 tty1 tty2 tty3 tty4 tty5 tty6 tty7 tty8 tty9 tty10 tty11 rsh rlogin ssh
4. vim /root/.rhost
[root@eptcproc5 ~]# cat /root/.rhosts eptcproc1 eptcproc2 eptcproc3 eptcproc4 eptcproc5 eptcproc6 eptcproc7 eptcproc8 eptcproc9 eptcprocdb
5. Aktifkan konfigurasinya
[root@eptcproc5 ~]# chkconfig rsh on
[root@eptcproc5 ~]# chkconfig --list rsh
rsh on
[root@eptcproc5 ~]# cat /etc/xinetd.d/rsh
# default: on
# description: The rshd server is the server for the rcmd(3) routine and, \
# consequently, for the rsh(1) program. The server provides \
# remote execution facilities with authentication based on \
# privileged port numbers from trusted hosts.
service shell
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rshd
disable = no
}
6. Cek service
[root@eptcproc5 ~]# chkconfig --list rlogin
rlogin on
[root@eptcproc5 ~]# cat /etc/xinetd.d/rlogin
# default: on
# description: rlogind is the server for the rlogin(1) program. The server \
# provides a remote login facility with authentication based on \
# privileged port numbers from trusted hosts.
service login
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rlogind
disable = no
}
7. Restart
[root@eptcproc5 ~]# service xinetd restart Stopping xinetd: [ OK ] Starting xinetd: [ OK ] [root@eptcproc5 ~]#
Lakukan konfigurasi yg sama di kedua mesin. dan jangan lupa install rsh dan rsh-server
