[SunHELP] Why I failed to run rsh command ?

[Li Jiang]

Greetings everyone,

I encounted a strange issue and want to get your advice.

I can run "rsh hostB" from hostA, but I can't run "rsh  hostB command" from 
hostA. As you know, "rsh hostB" is equivalent to "rlogin hostB". I don't know 
what's wrong. A little background, hostA and hostB are running SunOS2.7 and with 
tcp_wrapper installed(default configuration).

Thanks in advance.

Best Regards
John Lee
