1.1 root 1: This version of ftpd has been fixed to conform to RFC959.
2:
3: Unfortunately, this conformance introduces a user visible change. While
4: technically, this is the fault of the client (ftp) instead of the server
5: (ftpd), the change will be seen whenever an old ftp client calls a new ftpd
6: server.
7:
8: The problem is that the old ftpd implemented the NLST command by execing
9: /bin/ls. This produced non-conformant output in some cases. The new
10: ftpd no longer executes /bin/ls for the NLST command as it has it's own
11: built-in code.
12:
13: The user visible change in the ftp behavior is caused by the ftp client
14: "knowing" that the daemon will exec /bin/ls. This assumption should not
15: have been made.
16:
17: When the old ftp client is used, one of the options is the "ls" command
18: which sends the command NLST to the ftpd server. The client should really
19: be sending the LIST command. The new ftp client has been corrected to do
20: this.
21:
22: NLST should not normally be used directly by humans. It is intended to
23: interface with commands like mget or mput.
24:
25: Users who are not able to upgrade their ftp client may obtain the previous
26: behavior, by using the command "dir" instead of "ls".
27:
28: These changes only apply to those sites using code derived from the Berkeley
29: software releases (which means almost every UNIX based implementation will
30: see this problem).
