From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.3-20mdk i686; en-US; Galeon) Gecko/20010409 Description of problem: According to RFC 959 or whatever, every command should be replied to. However, if data has been transferred, SITE CHECKSUM doesn't produce a reply. As I understand this is still unimplemented and should return an error reply. The server doesn't freeze or anything, simply fails to produce an answer and thusly the client freezes. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. user + pass + whatever 2. retr or stor 3. site checksum Actual Results: no reply, but daemon still works. Expected Results: an error reply should be produced Additional info: A fix is IMHO straigthforward, it should be a one-line patch. I don't think it's critical, however causes temporary freeze on a rfc-compliant client and hence should be fixed. I'd have written to wu-ftpd directly, their site seems to be down however. I hope this has nothing to do with the terrorist attack and none of the developers were injured.
Please use vsftpd, wu-ftpd is not maintained anymore.
