Hi,

  I have Linux 1.2.8 installed on a number of 486DX/66.  I am using them
to form a parallel virtual machine.  When testing the systems, I found
two of the machines behaved strangely with such commands as telnet/ftp
/rsh/rlogin.  They don't connect if the remote host is a Linux box in
the subnet.  For example, when I issued the command 

telnet linux3

I got the following response:

Connected to linux3.....
Escape characters is '^]'
Connection closed by foreign host

But when I telnet to other non-Linux machines anywhere, it works fine.

I have also tried "rsh" and simply got 

linux3.merrick.miami.edu UNKNOW SERVER ERROR

 What should I do to fix this problem?

 Thanks.


 Cheers,
