Remember, emcrsh is using a Telnet compatible interface but it isn't a Telnet shell like rsh for example. Something like emcrsh isn't going to allow anyone to execute code on your machine or read your user or root passwords.
If you have a port open then a hacker can try accessing it. The worst they can do is guess at the password needed to log into emcrsh, assuming they manage to guess what emcrsh does. They could then interfere with operation of the machine. Just having a port open on your machine doesn't automatically allow others to scan any data going through that connection. The only way hackers can do that is if they can intercept the packets as the travel between the remote machine and emcrsh. If you are using emcrsh via a local network (a much more likely scenario), outside hackers won't be able to read your password or anything else. Most routers out of the box only allow access to a limited number of ports. If you are using emc locally then simply don't enable that port in your router/firewall. A much more likely scenario is a malicious user trying to mess around with a CNC machine that is on the same local network. However if you are running a business big enough to have malicious users on it's network you should already have security protocols in place. Les > > The problem is leaving the telnet port open.
