It is old discussion, but I do not read the list regularly... To those of you who use FTP and remote command. (well, I admit I do...) I ran a sniffer and saved it's log to a file, wich I then filtered through my Perl script which makes it more readable. Remote command run from AS/400 on PC gives you the SAME AMOUNT OF INFORMATION: user profile, password, what command you run, what did PC answer etc. If you will still like to use remote command, do not run the server all the time. OK, listen to example scenario: You have remote command server on a PC running. I start a sniffer and wait for as/400 to run a command on your PC. You do use user profile and password, yes? I sniff them and can run any command on your PC, like deleting files. I can ftp word documents from your PC to mine. I can install key logger on your machine and will be able to know your every keystroke! OK, here is the transcript of the session I got. Anyone can explain to me how can I still use FTP, but in secure way? Any simple (and free of charge) trick to find out whether anybody runs sniffer on the network? (maybe off the list, as it is not AS/400 related) David *************************** Janusz David Prusaczyk janusz.prusaczyk@big.pl tel. +48 (22) 657 57 48 *************************** _______________________ BEGIN TRANSCRIPT _________________ [10.2.1.63:21] -> [10.2.1.105:1335] .@220-QTCP at CENTRALA. 220 Connection will close if idle more than 5 minutes.
