Use this for any activity that doesn't *require* root permission. In the case of connecting to your FTP server, even if you ARE root at the time, it's best to use: #ftp username@host.domain.tld where username is the "other account." And Daniels is very correct about the security of even this issue. If you are connecting over the "outside" Internet these user/pass combos could be sniffed and used to gain access to your box. Investigate SSH ( try PuTTY) and SecureFTP a client is also available that corresponds to PuTTY....
