On the other hand, if we issue the quit in lowercase, everything goes smoothly. Another info, if we repeat the same test from a windows system, the filezilla server accepts the quit both in upper and lower cases. We can't change the QUIT command in the AIX procedure and we think that this case sensitivity applied in the first test, is not correct. Could you kindly verify?"
