Basic NFS is pretty evil. Totally insecure.
Well, it looks like most local traffic here uses evil things :-)
I imagine TFTP isn't less evil and perhaps only FTP is worse
(cleartext passwords over the wire and firewall problems). And
Samba (especially with unencrypted passwords) and X and...
The rsh protocol requires the server to make a second TCP connection
back
to a low-numbered ephemeral port specified by the client, for the stderr
channel.
Nope, that's optional.
If you haven't got a stateful, inspecting firewall, you're
hosed.
Even with stderr all you'd need is a simple helper.
Anyway most people use rsh* over physically secure networks.
Password-less privileged access with source IP access control over
public network? No, thanks.
