HI,

I installed on my fedora vsftpd server, I configure it but I am getting en error whan I try to access this server remotly or localy:

[root@juan root]# ftp localhost
Connected to localhost (127.0.0.1).
421 Service not available.
I see with netstat -tulp that the server is listening:
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 *:9098 *:* LISTEN 1491/xinetd
tcp 0 0 *:ftp *:* LISTEN 1501/vsftpd

the configuration of vsftpd.conf is:

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

Please help !!

thanks,

421 means that the remote connection is closed. There is something wrong in your config that's why.

Comment out "tcp_wrappers=YES" and restart the service and see if that fixed it. If it didn't, let us know and we'll help you debug this problem further.

-twantrd

thanks
It worked !

how I create usera and userb and give them full rights to /ftp folder and all the sub folders ?

thanks very much !

Juan

Cool it works .

Just create regular unix accounts for usera and userb on the box and put them in a group that has read,write,exec permissions for /ftp folder. You don't create ftp accounts under vsftpd, it just reads the usernames off of /etc/passwd.

Hi,

If it is not yo much to ask can u please show the exact commands? in mew to linux.


thanks very much. !

also do you think that by disabling the wrraoer option in th .conf file the server is less secured?

Juan

The commands are:

1. useradd -d /ftp usera
1a. passwd usera
2. vi /etc/group
3. chgrp foo /ftp
4. chmod 775 /ftp

That's pretty much it. I use 'vi' as my editor but you can use whatever you want (pico, nano, emacs, etc..). If you look at /etc/group, you'll see how the syntax for groups is layed out. In this example, I made a group called 'foo' and changed the groups for /ftp to have group 'foo' and made read/write/exec permissions on that.

Google on how user permissions and groups are in unix and you will get a much better understanding of how it works than me telling you .

You can increase security on your box with tcpwrappers but you need to setup your vsftpd a bit differently for it to work. If you secure your box very well and chroot() your ftp users, you should be fine.

Hi,


I notice that when connectiong to the ftp server I
configured from windows command line usung the command
ftp 192.168.1.10 everything is fine but whan trying to
connect from the same windows machine with an ftp
client as cute ftp pro 2.0 I can't connect !

This is the error messasge is see on the cute ftp:

*** CuteFTP Pro 2.0 - build Nov 20 2001 ***

Also what is the command to download throw ftp whole folders? is it possible?

Thanks very much !!
Juan

hmm...weird. It could be a setting in your cute ftp? I have no idea. You might want to take a look on google on that error code and see what others have to say about it.

-twantrd

I created the users and they logged in to /home/juanb which is the folder I want tham to be in but the thing is that the users can cd... and even get to / . what can I do to stop this?

tahnks !

Juan.

Like I said in my previous post:

-twantrd

how can I create one user let say max that he will be able just to download files but not delete any file?

thanks very much !

Juan

Read up on unix permissions....that's how.
