[tlug] whatis path-filter in /etc/ftpaccess (wu-ftpd)

[Nguyen Hung Vu <vuhung@example.com>]

hello all,

i have some questions about /etc/ftpacess:

1) in /etc/ftpacess:

# path-filter...
path-filter  anonymous  /etc/pathmsg  ^[-A-Za-z0-9_\.]*$  ^\.  ^-
path-filter  guest      /etc/pathmsg  ^[-A-Za-z0-9_\.]*$  ^\.  ^-

what is /etc/pathmsg?
what is the next regular expression?

2) when a user login ftp server, the version of wu-ftp shows up.
how can i disable it?

TiA
