双机相连错误

molucule

两台机器现在可以不要密码直接ssh，rlogin，rsh
但运行程序却连不上，错误如下：
connect failed: Connection refused
subprocess pid = 7339 has exited. status = 0x0100, id = 0, state = 13. command was /usr/sca/linda7.1/intel-linux2.4-ws3/bin/linda_rsh node2 -r rsh
died without ever signing in
Sign in timed out after 0 worker connections.
Did not reach minimum (1), shutting down.
已杀死
把这个命令单独拿出来试了一下，也连不上：
[]$ /usr/sca/linda7.1/intel-linux2.4-ws3/bin/linda_rsh node2 -r
错误如下：
Pseudo-terminal will not be allocated because stdin is not a terminal.
请教问题出在哪里？
