Make sure ftp server installed

Make sure ftp server installed and service is running. Under Debian Linux you can use dpkg command to verify that ftp server installed:
$ dpkg -l | grep -i "ftp"Output:

ii  ftpd                           0.17-21                       FTP server

OR run following command:
$ dpkg -l | grep -i ftp
Under Red Hat/Novell Suse/Fedora Linux try rpm command:
# rpm -qa | grep -i "*ftp*"
In any case if you have the ftp package installed it will return output. If the ftp package is not installed, it will notify you or it will not give you any output at all. Naturally next logical step is to install FTP server.

Under Red Hat/Fedora Linux install vsftpd server as follows:
# up2date vsftpd
OR if you are using Fedora Linux use yum:
# yum install vsftpd
If you are using Debian Linux use apt-get command:
# apt-get install vsftpd
Next configure vsftpd by modifying /etc/vsftpd.conf file.

Is ftp server running (is port 21 open)?

Login to ftp server using ssh and try to telnet port 21 (to see port is open or not):
$ telnet localhost 21
Next run netstat -tulpn command to see if port 21 is in open:
$ netstat -tulpn | grep :21

Output:

tcp        0      0 0.0.0.0:21             0.0.0.0:*               LISTEN

OR try following command:
$ netstat -a | grep ftpOutput:

tcp        0      0 *:ftp                   *:*                     LISTEN

If port is not open, start ftp server /service. Under RedHat/Fedora Linux use service command:
# service vsftpd start
Under Debian Linux use following command:
# /etc/init.d/vsftpd start

FTP user permissions

Is particular user not allowed to use your vsftpd ftp server, then make sure user got permission to use your ftp server. File /etc/ftpusers – list of users disallowed use vsftpd server access. Make sure user name is not in this file.

Security or Firewall

Make sure iptables firewall/tcpd does not block access to your ftp server. Run following command on ftp server (login over ssh):
# iptables -L -nOutput:

Chain INPUT (policy DROP)
target     prot opt source               destination
ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0
ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpts:6881:6882
ACCEPT     udp  --  202.54.1.254         0.0.0.0/0           udp dpt:514
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpts:80 state NEW,RELATED,ESTABLISHED
LOG        all  --  0.0.0.0/0            0.0.0.0/0           LOG flags 0 level 4
DROP       all  --  0.0.0.0/0            0.0.0.0/0

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0

Above output does not allows port 21 (port 21 is blocked by firewall). You need to use iptables rules to open port 21. Make sure file /etc/hosts.deny (TCPD wrappers) does not block access to port 21 for your ftp host.

    Just to note that for permissions on vsftpd for RedHat based distros the ftpusers file and others are here /etc/vsftpd/ftpusers NOT simply under /etc/ftpusers

    Great article all the same because it helped me out! I was looking for /etc/ftpusers but once I found this article pointing to vsftpd it all came together.

    I had same problem,gave me a lil headache trying to find a solution to it, I always got “connect: Connection refused” error.
    Then to resolve it, I checked my Redhat 5 server to see if ftp service is running,but alas it wasn’t just simply started it all everything became al-right.

    #service vsftpd start

    the cmd above was used to start my ftp service.

    so a couple days ago I spent all day trying to get ftp and ssh to work on a Linux server im setting up to use at a company. I followed every step by step guide perfectly but everytime I would try to connect I would get “connection refused error”. I came in to work today and the first time I tried to connect with ftp and ssh it worked perfectly. Turned out the problem was a conflicted ip address on the network. None of the forums I looked up suggested this and its a pretty easy fix so I would advise checking this if you are having ftp or ssh problems.
