Hi!

I've got the same trouble with FTP.

All is working from LAN and online ftp-clients (for example that).

But from another computer (but the same provider) i've got errors in "FileZilla" and "CuteFTPPro":

Code: Select all

Can anybody help us?

P.S.: port 2021 is external and forwarding by router to internal 21.

[raulfg3]

Please confirm if you use DHCP IP, I remember that a Fixed IP is needed to gain permission over the Wan ( but I don't remember why).

If dhcp, change to fixed IP and try it.

[d3st1ny]

I have not changed anything, but ftp started working properly

You may need to set the passive ports (min-max) in nas4free and open them in your firewall
http://doc.freenas.org/index.php/FTP

[d3st1ny]

again does not work

[Kiss239]

You may need to set the passive ports (min-max) in nas4free and open them in your firewall

It means, that I have to set redirecting for thouse ports [min,...,max] in router's DNAT config?

Please confirm if you use DHCP IP, I remember that a Fixed IP is needed to gain permission over the Wan ( but I don't remember why).

If dhcp, change to fixed IP and try it.

I use router's DHCP (IP is reserved by MAC) in "my own little LAN", and my provider use DHCP (auth by MAC) too, and he gives me external IP (xxx.xxx.xxx.73) for my router and NAS4Free server includingl; the same provider gives external IP (xxx.xxx.xxx.143) to another computer (client), which is not in "my own little LAN".
In settings of FileZilla (on a client computer) I've used option "use external IP", but error haven't gone.

May be I haven't understood something?

[raulfg3]

try to assing a fixed IP to your NAS (It can be the same that actually have , but fixed, not asigned by dhcp), and try if works.

PD: revise this [howto] : viewtopic.php?f=71&t=560

[d3st1ny]

i added record to file HOSTS: MY_HOME_IP MY_COMP_NAME
nas4free said:

Code: Select all

root: hosts service executed

and ftp began work
i don't understand anything

[Kiss239]

My NAS4Free server have got fixed external IP-port combinations via DNAT from router and fixed internal IP in my home LAN.

All adresses are fixed and permanent. Becouse of it I don't know what to do with this problem... (

[davidb]

On a related problem, i was getting some weird errors when i set up the ftp on my NAS4Free box:

proftpd: warning: host name/address mismatch: 192.168.XX.XXX != anothercomputer.my.domain
proftpd[2244]: 192.168.XX.XXX (192.168.XX.XXX[192.168.XX.XXX]) - mod_wrap/1.2.4: refused connection from ::ffff:192.168.XX.XXX

Turned out there was an old DNS entry in my domain controller for the IP i got via DHCP. Once i cleared that out it worked fine.
Seems that the RDNS lookup is still taking place even when not checked on the config page?

[planetcaravan]

I'm having the same problem.
Could this http://www.proftpd.org/docs/contrib/mod_wrap.html#FAQ help us?

[infinion]

I Fixed this error with adding the external hostname and internet ip in -> GUI -> Network -> Hosts. Make a new entry with your Hostname and IP. Save and you should be able to connect.

[planetcaravan]

I've set my dyndns name and my public ip address, Is it correct?

[planetcaravan]

I can't find my old file as I think I'm having problem both on OS (on usb key) and raid

[infinion]

That sounds correct, i did the same.

[planetcaravan]

I've set my dyndns name and my public ip address, Is it correct?

Can someone help me, please?

[nicolap8]

I think that here is the solution: add to Auxiliary Parameters the "DynMasqRefresh" directive!
http://www.proftpd.org/docs/contrib/mod_dynmasq.html

But is needed a recompilation of ProFTPd!
In past I already tried to request this change but "they" (I dont remember who) sayd "NO"...

[planetcaravan]

So is not possible to recompile ftp server in NAS4Free?

[planetcaravan]

Hi there!
Can somebody help us?

[alexey123]

What problem recompille any service?
Create jail , than

Code: Select all

portsnap fetch extract
cd /usr/ports/ftp/proftpd

Then as in handbook
Recommended Test Ordering

• make install
  make package
  make deinstall
  pkg_add package-name
  make deinstall
  make reinstall
  make package

Package can be installed on base system - new buillding must replace binaries.

I had to manually # comment out the :

Code: Select all

# <IfModule mod_wrap.c>
#  TCPAccessFiles /etc/hosts.allow /etc/hosts.deny
#  TCPAccessSyslogLevels info warn
#  TCPServiceName ftpd
# </ifModule>

then from command line -HUP the proftp process... If you do it from GUI it puts the commands back, probably easier way to do this, but need a quick fix....

/var/etc/proftpd.conf

[alexey123]

/var/etc/proftpd.conf

This file rebuild every reboot from your config.xml and /etc/rc.d/proftpd script.

[planetcaravan]

Hi,

I've changed the file as you've done, but I'm still having the same problem CAUSE each time I restart FTP service, nas4free eliminates comment on configuration's file!

[yozh]

Yes thats why I said you have to -HUP

[planetcaravan]

Sorry!

So what we're gonna do?
