不要著急，在linux主機上，tail -f /var/log/messages，我們會發現如下信息
Jan 14 21:43:10 Sim32_01 pam_rhosts_auth[28313]: denied to userofwinsows@windowsserver as useroflinux: access not allowed
Jan 14 21:43:10 Sim32_01 in.rshd[28313]: rsh denied to userofwindows@192.168.100.151 as useroflinux: Permission denied.
哦，原來是pam.d的事兒啊...vi /etc/pam.d/rsh,裡面內容如下：
#%PAM-1.0
# For root login to succeed here with pam_securetty, "rsh" must be
# listed in /etc/securetty.
auth required /lib/security/pam_nologin.so
auth required /lib/security/pam_securetty.so
auth required /lib/security/pam_env.so
auth required /lib/security/pam_rhosts_auth.so
account required /lib/security/pam_stack.so service=system-auth
session required /lib/security/pam_stack.so service=system-auth
把auth required /lib/security/pam_rhosts_auth.so
這一行註釋掉，再試，OK,搞定！
