vsftpd problem..


hi,

i have a rough vsftpd configuration. my main problem is that, vsftpd never authenticate the user. it always login as an anonymous.

ftp syproxy
Connected to syproxy.shinyang.com.my.
220 (vsFTPd 1.2.1)
530 Please login with USER and PASS.
530 Please login with USER and PASS.
KERBEROS_V4 rejected as an authentication type
Name (syproxy:root): yohiu
530 This FTP server is anonymous only.
Login failed.
ftp>


actually, i want to disable the anonymous login. but, it cant make it, eventhough after i had stated "anonymous_enable=NO"

this is my /etc/xinetd.d/vsftpd
service ftp
{
disable = no
socket_type = stream
wait = no
user = root
server = /usr/sbin/vsftpd
nice = 10
}


this is my vsftpd.conf file.

# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.

#
# You may activate the "-R" option to the builtin ls. This is disabled by

pls advise.. thanks.....

you will have to set

LISTEN=no

if you want to run vsftpd under xinetd.

Not sure about the consequenses of vsftpd running as a daemon and as a xinetd subservice simultaneously.

man vsftpd.conf

listen If enabled, vsftpd will run in standalone mode. This means that
vsftpd must not be run from an inetd of some kind. Instead, the
vsftpd executable is run once directly. vsftpd itself will then
take care of listening for and handling incoming connections.

Default: NO


Please make sure there do not exist 2 copies of vsftpd.conf ... a very wild guess.

try setting LISTEN = no in vsftpd.conf and restart vsftpd

# kill -1 `pidof xinetd`

to be sure 2 vsftpd servers are not running to ensure your anonymous problem is not due to this.

I just did a clean install of vsftpd 2.0.1 and am able to logon with a local user. I am also running in standalone. I did change my vsftpd.conf to something very similar to yours, but I had to kill vsftpd and then restart it. Another you may want to check is if your local user is a member of the group 'ftp'. This may be only in Slackware, but it works for me.

Here's my vsftpd.conf:

Code:
# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.

# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022

Go here:
http://www.vsftpdrocks.org/source/

This page is by far the simplest and most helpful for setting up vsftpd as either standalone or through xinetd and for authenticating users (see the bottom of the page for users).

Hope this helps.
