Ubuntu Networking :: VSFTPD Can't Connect PASV On WAN?
Oct 28, 2010
I'm having a peculiar problem. I have VSFTPD working and everything works great on my local network! The only problem is that I can't get PASV mode to work over the WAN.
I've tried everything:
- making sure the pasv_enable, pasv_min_port, and pasv_max_port variables are set in vsftpd.conf
- punching holes in Shorewall for these ports via rules
- setting up port forwarding for these ports in my routers (although this might be unnecessary)
The problem, is PASV mode works fine when I access from either router (my server is behind two routers but not from my WAN IP. Could this be a problem with my ISP?

My organization has been using PASV FTP via VSFTPD for some time now. We have defined the port range between 30000 and 33333 and as I mentioned, it has worked up to 20100108 (last Friday). It appears that VSFTPD is not negotiating the defined PASV port range, which we can see with both netstat and tcpdump. Has anyone here run into this before? Are there any VSFTPD hackers out there who know what mechanism VSFTPD is using to re-allocate the ports? I would think that it would release the port, and flag it as unused, or something.

This is as far as FireFTP can go to make a connection.
Code:
220 Welcome to Steve Test SFTP service.
AUTH TLS
Proceed with negotiation.
PBSZ 0
All the basic vsftpd.conf advice followed:
Code:
ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=NO

I have installed vsftpd and I configured the whole package and everything worked. But, after a reboot, it doesn't work anymore. Vsftpd is running. When I do "telnet localhost 21" the machine gets connected to localhost. It also succeeds when I type "192.168.2.10" (my internet IP address) or "86.80.107.30" (external IP address). So the connection is fine. I configured vsftpd to allow only given users, in this case the user bourne. Everyone else isn't allowed to use vsftpd. My main account is stan. So when I connect to the machine via SSH, I'm logged in as 'stan'. When I try to log in to the FTP server with "ftp localhost" and I fill my own username I get an error message saying permission is denied, I don't get a chance to enter my password. When I fill in the username 'bourne' it asks for a password, I enter it, and I get the message 'login incorrect'.
But now it's getting weird: When I switch to the user bourne in the shell by 'su bourne' and enter the same password for FTP, I get logged in as bourne. Then, when I enter 'ftp localhost', fill in the username 'bourne', enter its password, the login is succesfull! It doesn't matter where I connect to (local IP, external IP, localhost, or computer name) I get connected with the user bourne as long as I'm logged in to the shell with this user. Otherwise it doesn't work. Does anyone know why? Below is the config file of vsftpd:

I just made a Ubuntu Server install in a virtual machine and am having trouble setting up FTP to transfer files. I've installed LAMP and vsftp. The web server works great, but FTP gives a connection refused error locally and remotely from the host machine. 'Connection attempt failed with "ECONNREFUSED - Connection refused by server".' nmap localhost doesn't list FTP as open even though I have vsftpd set to listen. I've tried restarting vsftpd with no luck.

I set up a ftp server using VSFTPd. Remote connections are working fine. I can connect then create, rename and delete folders. I can upload files without any issue. BUT, each time i connect directly from the server (with the command "ftp localhost") i can't upload files either delete them. The only thing i can do is create folders. I'm getting error code "553: could not create file" when trying upload files. I triple checked the rights, everything is OK. I disabled SELinux (even if i don't like it). The weirdest thing is everything's working fine from remote host.
Below my vsftpd.conf:
listen=YES
tcp_wrappers=YES
anonymous_enable=NO
local_enable=YES

I'm running vsftpd-2.2.2 on Slackware 13.1 and I'm behind a NAT with a dynamic IP. I'm using pasv_address, which makes it necessary to have a crontab that checks whether my IP has changed, and if it has, edits the conf and restarts vsfptd. It's hackish but it works. I have also enabled FTPES on the same port that normal FTP runs. I have allowed only the 5001:5003 ports and I am aware that the recommented is 50 ports. However I never had an issue with the transfers since I'm the only user and have at maximum two simultaneous transfers.
I can connect remotely with FTP and FTPES with every client I tried but I'm having issues locally. FileZilla refuses to connect on FTP and FTPES. WinSCP can connect on FTP but not FTPES. Issues are gone if I enable pasv_promiscuous, which the manpage strongly recommends not to use unless "you know what you're doing". I don't. Why is this happening? And, can I fix the local connections without resorting to pasv_promiscuous?
Here is my config and log files from a failed local attempt.
vsftpd.conf
Code:
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022

BAM your ftp doesn't work. Out of the blue my ftp connections stall when I ask for a directory listing. I am using ncftp as I have for several years. And after a long pause I get the answer:Data connection timed out.Falling back to PORT instead of PASV mode.I then get the listing and the connection continues in PORT mode. But not with FileZilla it just hangs. Also bit torrent no longer works. Set up is a home network of 6 machines reaching the internet through a linux firewall box, qwest DSL modem gt-701-gw. Nothing has changed but sometime in the last week something has changed because now FTP PASV and BIT TORRENT can no longer connect.
I am holding back from completely rewritting the iptables/shorewall rules and have spent the day with the website host 1 and 1 and Qwest. Trying to find a solution. This problem is universal, all machines (windoze and linux) and all software (coffeecup, ncftp, ftp, filezilla, bit torrent).

I have a situation when vsftpd do not allow to get files from directories deeper than chrooted directory.
I can get from chrooted directory.
I can put to chrooted directory.
I can put to deeper than crooted directory.
I can list directories and files deeper than chrooted direcotry.
But I can not get files (process starts and hangs) from directories deeper than chrooted.
Firewalls on both sides (client and server) are set to log every in and out connection that do not -j ACCEPT. Log files are empty, so I assume nothing is blocked by firewalls.
Permissions for files and directories, I want to get, are set to 777.

My apologies if this is the wrong board for this thread, but seeing how the issue appears to be related to where I'm connecting from, I thought this would be the place to look.To start off, I've been running VSFTPD on the box for a good year or so now. Until recently, everything seemed to be working fine, but during the past few days I've run into issues with it and have been having trouble pin-pointing the problem. I've gone as far as reinstalling VSFTPD and rechecking every line in the conf file to no avail.The issue presents itself when I try to login to the FTP server remotely. The moment I put my user name in, I get disconnected without any error message, simply connection closed. That isn't the case when I'm connecting locally from the server.If I try to connect remotely using eth0 (internal network), it works fine again... but if I try eth1 (external network)... it fails. I'm thinking it might be related to PAM, but so far have been unable to figure out what I need to change in the configuration there. Additionally, the PAM log file doesn't show any activity if I'm connecting through eth1, but displays it if connecting through eth0.

I have a running instance of vsftpd. It works like I want for ftp.thisdomain.com and now I want to have it serve for ftp.thatdomain.com from a diifferent document root at the same time. Just lik I can do with Apache. Is this possible? So browsing to ftp.thisdomain.com will take you do /home/ftp/.And browing to ftp.that domain. com will take you to /home/ftp/thatdomain/

I'm kinda new to all of this so I believe there's a simple solution for what I need I just don't know how it's done.
So I've configured a vsftpd, ftp server and enabled the anonymous user, therefore when I do
Code:
ftp://my_location.com
a directory like view is displayed in my web browser, corresponding to /srv/ftp where the files for the anonymous account are kept. Now I've made a little web page and I've copied it there, and can be executed running main.html so the address to access the web page would be
Code:
ftp://my_location.com/main.html
My problem is that I don't want anybody to have the possibility to see the directory like display so I'm wondering if when someone does ftp://my_location.com can't this be redirected so it will do ftp://my_location.com/main.html instead?, making the display of files and directories impossible from the ftp://my_location.com

I am trying to create multiple FTP sites on one Linux server (using multiple vsftpd-sitename.conf files) with default port '21'.
Below is the sample vsftpd site configuration,
# cat vsftpd-site1.conf
listen=YES
write_enable=YES
[code]....
I am unable to create above vsftpd site with port '21'. Below is the problem,
# vsftpd vsftpd-site1.conf &
[1] 14448
500 OOPS: could not bind listening IPv4 socket
I wonder, i can able to create above FTP site with another port (example, listen_port=60001 ). In Linux(vsftpd), can i use default ftp port '21' for multiple FTP sites?

This is on Centos 5.3 by the way..... I had a DVD and, well, just wanted to test some things.. I'm aware that this is not the latest release.
And, by the way (I just read an earlier post) I've added the username and password with which I'm trying to login (..hello?).
I'm at work and I don't have a copy of my Vsftpd configuration file (don't wanna edit this whole thing - actually there is a copy, below). I've used Slackware for years and never had any issues with Vsftpd - it just works. I am trying Centos because I need help with upgrading my mail server (qmail) and there's not much help for Slackware users. Also, I used to run RHEL3 and had vsftpd working fine (had to copy some file to /etc/pam.d) but it worked famously. I compiled all my web server stuff (just don't like these default things where I have no idea how things are integrated) and I'm hung up on - of all things - vsftpd.
Anyway....When I try to log into my ftp server I get "KERBEROS_V4 rejected as an authentication type" and only the anonymous account works. Any other logins produce an error (incorrect login - see ya' later). I have SE Linux and the firewall OFF. I don't recall the directive, precisely, but my vsftpd.conf file is set allow local users to connect. I installed with yum and it added some lines at the bottom (one was about a user list and the other was about PAM). I've got a chroot list and a user list although it's not clear to me precisely where the user list should be placed. I actually uninstalled the RPM and compiled, too. I've done everything but call an exorcist. And I've found tons of posts regarding this on the net and none of the fixes worked. Man - on slackware you type "make" and "make install" (I build it with tcp_wrappers) and you're off to the races.
Actually - I did upload the vsftpd.conf file to work (where I'm at, now). Minus lines that were commented out it looks like this:
Could it, possibly, be something about how I am adding the user, the shell type, etc? I know that in Redhat I used to type "/usr/sbin/useradd -d /home/someuser joe". I've done it that way and I've also done it like so: "useradd -d /home/schmoe -s /bin/bash schmoe".

I'm trying to get vsftpd running with both anonymous and local user access to the same folder. The directory I'm using is /tftp with the following permissions:
dr-srwxrwx 7 root root 12288 2009-08-14 15:54 tftp
My vsftpd.conf is this:
anonymous_enable=YES
local_enable=YES
write_enable=YES
[code]....
I set the default "ftp" user's home directory to /tftp (was /var/ftp).

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
