Hi, yes, the general wisdom is to avoid telnet anymore, unless you are sure you are on a secure network. Installing to 70 servers, probably requires root access, which would be bad to pass those passwords over a network.....even a local net....who knows who is snooping.

Even with ssh, they usually disallow root ssh logins, so the method is to login with a user thru ssh, then su to root....that way, it's all encrypted network trafffic.
