What do you mean, "get real". If that is all your 2 cents you might as well keep them, thank you.
Gunther knew exactly what I meant but if I have to spell it out. Doing any install on a network carrying potentially hostile traffic is a security risk. That includes ftp, nfs, smb and CDROM.
Incidentially, I'm just running a few boxes behind a thorough firewall; and I want to install via ftp. I am not prepared to buy CD drives for every P133 in our office. THis is not a setting that requires a paranoic handling of things, and I have decided that installing via FTP is just fine and very conveniant in *MY* situation, that you do not know.
Thinking you're safe behind a firewall is a fools paradise. At the end of the day, you, the sysadmin have to weigh the risks but remember Murphy's law - if anything can happen, it will when you least want it to. John
