How do i connect externally via FTP? get connection refused

Hi.
I want to connect via ftp to my bubba 2.
I have tried to mount via map network drive, also tired "connect to a web site..." option in the map network drive window. Get no access.
I Have also tried filezilla, port 21 and 20, i get connection refused all the time.

I have enabled all the options in the bubba settings:
Allow ftp access
Allow anonymous ftp access (is that safe when thinking of hackers?)
In the firewall, all the settings is on, including the open port 21.
I have also tried to open port 20.
SSH is enabled.

Am i supposed to write anything after the ip adress? like xyz.xyz.xyz.xyz/username ?
What should i write in map network drive? i get error if i only use my ip, so i tried ftp://myip, http://myip
ftp://myip/username and so on...

Have i missed something?

Thanks for replies in advance.

Windows 7 64 bit

Try it from a command line:

Code: Select all

ftp
open [ip address]
See if that works.

Hi 86ivar,
Allow ftp access
Allow anonymous ftp access (is that safe when thinking of hackers?)
In the firewall, all the settings is on, including the open port 21.
I have also tried to open port 20.
SSH is enabled.
First check that proftp is running properly. If you have SSH access, use ps:

Code: Select all

$ ps -ef | grep proftp
Are you trying to access it from your internal network, or from outside?
From your internal network, it should just work out of the box.
Try using the IP address rather than the host name from your Windows box.
If it is from the outside, more considerations might have to be taken, with firewalls, port forwards etc.
If so, please tell us a bit more about your network setup.

Best regards,

Cheeseboy

ftp open [ip adress] : nothing happens.

ps -e | grep proftp, i get:
username 11337 11230 0 21:20 pts/0 00:00:00 grep proftp

i want to connect to it from my own pc at school, or anywhere else i might be. In other words, from the outside. it works fine in my internal network.
I have my schools network at home, dont know if there is any firewalls etc. but I think they have a restriction that makes it hard to upload torrents due to piracy.
Is there any other way to make a network folder to it in windows if this is too difficult?
looking at the manual, ftp connection from the outside should be easy.

It looks like your FTP server isn't running. Either try restarting it from the web interface or do this as root from the command line on the Bubba:

Code: Select all

/etc/init.d/proftpd start

Weird, that looks like it is not running, but if it works internally, it is.

Most workplaces and schools limit the port numbers allowed for outgoing traffic.
For example my workplace only allow port 80 (web) and 22 (SSH) outgoing.

All you need is SSH though, so as long as you get that, you are OK.
SSH will let you tunnel all other things, so you can work around all those pesky policies.

If you are using a Linux machine, or if you have something like Cygwin installed on windows (strongly recommended), you could just do:
ssh username@hostname.com -L9921:yourinternalbubbaname:21 -L9920:yourinternalbubbaname:20

Then ssh will open two local listener ports (20 and 21) and forward all traffic to your bubba.
If you use Windows and putty, it should look something like this:
[image removed]
The port numbers in the screenshot are of no relevance to FTP, you will have to replace them with 20 and 21.

i tried to restart the ftp with the command, get:
starting ftp server: proftpd - ipv4 getaddrinfo 'bubba' error: name or service not known
warning, unable to determine ip adress of bubba
error: no valid servers configured
fatal:error processing configuration file /etc/proftpd/proftpd.conf
Failed!

Maybe the settings is messed up because i have had some power surges?

Hi,

I find it strange that you do not have the hostname of b3/bubba itself in the /etc/hosts file.
This is mine:

Code: Select all

$ cat /etc/hosts
127.0.0.1	localhost.localdomain	localhost
192.168.10.1	b3.localdomain	b3
...
The error message sent in by ivar86 indicates this entry missing might very well be the cause.

Now, I have been tinkering with some scripts when I first got my b3 in order to get the DCHP/DNS functionality to work as I wanted. This was like a year ago, so I don't remember exactly what I did, and I'm not sure if what I have in /etc/hosts is standard. If you use another DHCP server on your network to assign an address to the bubba , it will not be as easy as to just modify the file, there is something wrong in a script that should update the file...

Perhaps best to let Excito comment on this...

yeah, I agree, there is an entry missing in the hosts file
if you do a

Code: Select all

 cat /etc/proftpd/proftpd.conf|grep ServerName
this servername should be in the /etc/hosts
I guess this should do it:

Code: Select all

su -
echo "192.168.10.1   b3.localdomain   b3">>/etc/hosts
/etc/init.d/proftpd start

Hello,

After a new install of my Bubba 2 the ftp server wasn't working. I'm a linux noob so I'm trying to figure out how to solve my problem through this forum.

I tried the "start" command and got the message that the serveradress couldn't be found. When I tried to list the adress in the hostfile it read: "Bubba"

So I figured that this is the same problem as above and I tried to edit the hostfile the way you provided.
I tried "192.168.178.47 b2.localdomain b2" and "192.168.178.47 Bubba.localdomain Bubba" but that didn't do the trick (192.168.178.47 is the local adress of my Bubba2). So I think this is not the right serveradress. Might any of you know which to use?

Thanks.

how can it not be the right serveraddress if you are sure it is the address for the B2? May be you are not sure of the correct address? what if you FTP to the IP address directly? Can you ping the IP address directly? What's in the log files?
