hallo,
to the moderator: i guess my first post never reached the list (my reverse dns
does not resolve).
second attempt from a different place...
aix 5.1-ml01 ftpd does strange things when supplied the notorious globbing
pattern.
although it does not crash, it produces interesting repeating (and repeatable)
series of outputs.
run "ls ~{" once --> get an error message --> see the example session below.
after that you will not be able to run any commands and will get a connection
refused message.
then, however, after several attempts the functionality restores.
i guess the question here is if it is possible to make it never return to
normal functionality.
Example session:
ftp> ls
227 Entering Passive Mode (10,0,32,2,128,250)
150 Opening data connection for /bin/ls.

i am pretty sure aix 4.3.3 ftpd will behave similarly.
i did not have time to mess with it enough,
just thought it was interesting (hi, troy :) )
