Hai i want to enable rsh service in my linux machine.
after that i want to connect from windows to linux.

i added rsh in /etc/securetty file.

then i added enable=no in /rsh file.

But i could not connect from windows to rsh.
It saying permission denied.cant establish connection.

Do you have installed the server part? Use your package manager to do so, and search for "rsh" or "rsh-server".
Once installed, be sure it will run automatically by properly configuring services
Generally, "ssh" is said to be more secure than "rsh".

Like jf said, you need to have rsh-server installed.

You also need a /etc/hosts.equiv file with the IP and username of the servers allowed to access your rsh service.

Once rsh-server is inplace you have to restart the inetd or xinetd service (depending on os version, new versions use xinetd)
the command is:
service xinetd restart

view the /var/log/messages file after you see the connection refused message. Usually it will give you a hint as to what the problem is.
ie:
tail /var/log/messages

Hi to jf. I have fond memories of Toulon France from many moons ago.

FYI, I did all of the above and then some, no luck.
I am running CentOS 6.3 with xinetd, so rsh is a subservice of that.

Here is what I did that finally worked:

vi /etc/xinetd.conf

# Comment out the lines that say "enabled" like this:
# enabled = rsh

# Uncomment and add any junk after "disabled":
disabled = anyjunk

:x

/etc/init.d/xinetd restart
rsh myunsecuresystem pwd


I still cannot rsh localhost, but who cares?
