Should I use Telnet and FTP for remote access?
Answer:
In a word, No.
The problem with Telnet, FTP, and other non-encrypted protocols is that everything is sent across the network as plain text. This means that someone running a sniffing program on the network, which is very simple under many circumstances, can see all of your traffic - including your login and password.
Consider replacing Telnet and FTP with SSh.
