Re: Is message id TCP12AF a security risk?

Found something!
When you use the ftp client on IBM i you can use the ftp subcommand SYSTEM
and it will return:
215 OS/400 is the remote operating system. The TCP/IP version is "V7R5M0".
from a dos client:
ftp> quote system
215 OS/400 is the remote operating system. The TCP/IP version is "V7R5M0".
This knowledge may help my google-fu

I'm trying to find how the system initiating the ftp to the other system
knew it was running "OS/400". I tried a STRCMNTRC to see if there was a
glaring entry in there. Like, maybe something like these kind of messages
getting processed
220 Connection will close if idle more than 5 minutes.
but I couldn't see it.
