Rsh To An Ipv6 Address

I am able to use ipv4 with no issue.

rsh < windows ipv4 > hostname

it WORKS !!

but ,

bash-3.00# rsh < windows ipv6 : fd20:8b1e:b255:40fa:bd1a:314f:abb4:48d9 > hostname

fd20:8b1e:b255:40fa:bd1a:314f:abb4:48d9: Connection refused

I used netstat -ano and found that the ipv6 port is black and not showing as listening or established.

i am using Cygwin in this windows machine to accept rsh/ssh/telnet request from any unix machine.

After few trial and error - I was able to ssh to the windows client using ipv6 address. but rsh using the ipv6 address is still not working.

Please note [ I am trying to rsh to the windows using windows ipv6 address from a Unix machine ]

Am sure ssh and rsh uses different ports . Not sure how to check if they are open.

Do you think installing Windows Bind service would help, if i edit the named.conf file to allow ipv6 address .

Thanks in advance.

Have you come across such a setup ( rsh to windows ipv6 address )
