Hi, I am a newbie and I have Wu-ftpd 2.6.2 installed on Linux
slackware 8.1
I want to set up anonymous ftp access

when I try to ftp localhost I get:
root@helpdesk:/etc/ftphosts# ftp localhost
Connected to localhost.
220 helpdesk FTP server (Version wu-2.6.2(1) Tue Jun 15 12:33:43 CEST
2004) ready.
Name (localhost:bb): anonymous
331 Guest login ok, send your complete e-mail address as password.
530 Login incorrect.
Login failed.

When I check my system logs I get:

Jun 16 14:40:16 helpdesk ftpd[29566]: rhost_ok: sethacc failed
Jun 16 14:40:16 helpdesk ftpd[29566]: FTP LOGIN REFUSED (name in
/etc/ftphosts) FROM localhost [], anonymous
Jun 16 14:40:16 helpdesk ftpd[29566]: ACCESS DENIED (error reading
access file) TO localhost []
Jun 16 14:40:16 helpdesk ftpd[29566]: FTP LOGIN REFUSED (access
denied) FROM localhost [], anonymous

My ftpaccess file looks like this:

class all real,guest,anonymous *

limit all 10 Any /etc/msgs/msg.dead

readme README* login
readme README* cwd=*

message /welcome.msg login
message .message cwd=*

compress yes all
tar yes all

log commands real
log transfers anonymous,real inbound,outbound

shutdown /etc/shutmsg

email user@hostname

I've checked the permissions on the ftpaccess,ftphosts file, they should be OK.
Does anyone have an idea what's going wrong?
