Review the *.te file to ensure it is appropriate.īe careful here, as opening up too many SELinux rules can leave you vulnerable. the *.te file is readable, the *.pp is compiled. In your current directory, there will be two new files: my_vsftp.te and my_vsftp.pp. Grep avc /var/log/message | grep ftp | audit2allow -M my_vsftp # replace the following with your tuned grep (if necessary) Once you're satisfied with the list of denials that need to be fixed, generate a new policy using the following: # ensure you have audit2allow var/log/messages will amass a list of errors that need to be fixed in your SELinux policy. It's often useful to temporarily put the system in permissive mode ( setenforce 0), then perform the operations you expect to need. Tune the grep statements as necessary to whiddle the information down to only the statements you want to fix. Review the output and decide whether the denials are erroneous, given your desired configuration. Try this (as root): grep avc /var/log/messages | grep ftp For Logon type input your account credentials in User and Password.You can usually find selinux denials in /var/log/messages.Next, input the hostname or IP address in Host and add the Port.If you're using FTPS select TLS for Encryption.To use the FileZilla client to connect to your Ubuntu FTP server, install and launch the app. Sadly there is no FileZilla FTP server for Ubuntu or other Linux distros. An open source solution, this is available for Windows (as well as a server), macOS, and there are 32-bit and 64-bit versions for Linux. Want something more intuitive, or accessing the FTP server from another operating system? You'll need an FTP client and arguably the best available is FileZilla. You can then use the get and put commands to transfer data. When prompted, input the username and password you set earlier. You can also use the IP address sudo ftp ipaddress On Linux, you can access the server in the terminal with sudo ftp hostnameīe sure to substitute "hostname" with your server's hostname. In nf, find and uncomment this line (remove the #): chroot_local_user=YES With chroot we can restrict each user to its home directory. Open it to edit: sudo nano /etc/nfįind write_enabled and uncomment the entry, ensuring it is set to "YES": write_enable=YESįor publicly-accessible FTP servers you'll want to limit what access each user has. You'll also want users to be able to upload files. If your distro uses a different firewall or you've installed an alternative, check the documentation to open the ports. To enable access via port 20, use sudo ufw allow 20/tcp By default, these are closed for security reasons in ufw (Uncomplicated Firewall). Secure Your Ubuntu FTP Serverīefore setting up a connection, however, you'll need to ensure FTP ports are open in Ubuntu. When you first connect to your Ubuntu FTP server, you should see testfile.txt. With the username and password set, create a test file in the account's home folder to confirm it works: cd /home/username (Substitute "username" with your intended username.) sudo password username With this you can use any FTP client to access the files hosted on the server via vsftpd. The first thing you need is an FTP user account. With vsftpd installed you can begin configuration. With that done, launch the service with: sudo systemctl start vsftpdĬonfirm the server is running with: sudo systemctl enable vsftpd This means if anything goes wrong, the default config can be restored. Start by making a copy of the original config file. Once installed, it's time to configure vsftpd. If not, simply install with sudo apt install vsftpd You should find vsftpd near the bottom of the list. To check, open a terminal window and input sudo apt list -installed Follow the steps below to install and configure an FTP server on Ubuntu with vsftpd. Installing an FTP server on Ubuntu is straightforward.
