Linux online file sharing

How to share files/media online

Can someone can direct me to a how to that explains not only how to install an FTP but also how a family member on another coast can access this via online? I have setup an old computer with the intent of sharing movies/music/photos with family members not in my house. I have been searching for over an hour and cannot find a complete guide from installation through user/folder setup to access via a computer not on the same network. Any assistance in this matter would be eternally appreciated.

If you want to setup your own server, I’d recommend to install something like «owncloud» which is a web application for uploading and sharing files using the web browser (such as dropbox, iCloud or ubuntu one) (more info http://owncloud.org/)

To install it on your ubuntu computer (that will work as the server)

sudo apt-get install owncloud 

You can then access the server using any web browser by entering the url http://YOUR-IP/owncloud , it will ask you for the basic config (such login info) the first time you enter.

Keep in mind that if you’r going to access the server from outside your house (or network) you will have to redirect port 80 from your router to your server.

Also, home internet connections are not designed for servers, thus the upload speed is normally low for a server, so expect no-so-fast file transfers when moving files from the outside to your server and the other way around.

I would also consider getting a free account from a cloud provider (ubuntu one, or dropbox, they both offer 5 gig free) and use that to share files, its simpler, faster, you dont have to worry about setting or mantaining the server yourself.

Cloud file sharing involves a system where users are allocated storage space on a server and are allowed to perform read and write operations on the data they save in their space online.

How to quickly set up http file sharing on GNU/Linux

If you have a good internet connexion it could be useful to be able to share files with friends via a home made solution.

We will see here how to set up a web server in order to easily share files via a http protocol on GNU/Linux.

The goal here is to do it quickly with minimal configuration.

We will use lighttpd wich is an open-source web server optimized for speed-critical environments while remaining standards-compliant, secure and flexible.

Small CPU load and low memory footprint, everything I’m looking for.

Installing lighttpd

Edit configuration file

• Edit /etc/lighttpd/lighttpd.conf, and add this line :

• Create upload directory :

• Create example file :

• Reload lighttpd service :

Connect to the web server

• From your web browser connect to your newly web server (http://IP_ADDRESS/upload). From the Index of page you should see your file :

How to secure?

We have a our brand new http server but if we make it accessible from the internet (that’s what we wanted right?), everyone can potentially connect to it.

We will see here, how we can improve security.

Firewall rules

We can use the netfilter/iptables or nftables firewall to restrict access and thus allow only certain ip addresses.

Netfilter/iptables rules

root@host:~# iptables -A INPUT -p tcp —dport 80 -m state -s ALLOWED_IP —state NEW,ESTABLISHED,RELATED -j ACCEPT root@host:~# iptables -A INPUT -p tcp —dport 80 -m state —state NEW,ESTABLISHED,RELATED -j DROP

nftables rules

root@host:~# nft add rule ip filter INPUT tcp dport 80 ip saddr ALLOWED_IP ct state new,established counter accept root@host:~# nft add rule ip filter INPUT tcp dport 80 ct state new,established counter drop

Add authentication

We can also add a user/password prompt window to prevent unwanted users.

• Edit /etc/lighttpd/lighttpd.conf, and add this lines :

server.modules = ( «mod_indexfile», «mod_access», «mod_alias», «mod_redirect», «mod_auth», «mod_authn_file» ) auth.backend = «plain» auth.backend.plain.userfile = «/etc/lighttpd/lighttpd-plain.user» auth.require = ( «/» => ( «method» => «basic», «realm» => «Auth», «require» => «valid-user» ) )

• Add new user login:password :

root@host:~# echo «agent007:secret» > /etc/lighttpd/lighttpd-plain.user

• Restart lighttpd service :

root@host:~# systemctl restart lighttpd.service

• The next time someone tries to log in an authentication request will appear :

Add https support

• Create a self signed certificate :

• Set rights :

• Edit /etc/lighttpd/lighttpd.conf, and add this lines :

• Restart lighttpd service :
