Ubuntu Servers :: Access Stuff (File) Over The Private Internet
Aug 8, 2011
I'm a absolute "server- noob" but I've got some experienced with desktop linux and want to build my own file server to access my stuff over the internet. I'm using dropbox for a while now like a cloud drive by simply mounting the "private" folder (which I encrypted with encfs/BoxCrypt) in order to cross-platform use important files. The problem is that Dropbox only provides 2 GB for free and I don't know how secure my data is up there. Moreover I don't wanna always sync all files locally.
I got an intel atom machine standing around and so I want to build my own file server to provide the same or at least a similar service.
1. Which type of server application provides a "network drive" that computers (several users) from the internet can access?
2. What's the best way to encrypt my data and transmission in order to make the system absolutely unattackable/unreadable from outside?
3. Is there a service that can provide a dropbox-style sync mechanism?
4. Which distro should I use? I'd prefer a non-desktop enviroment solution but never had anything to do with it. Is that possible for an average linux user?
I'm aware that this solution won't be very fast because of the limited upload of a standard internet connection but that would be ok! It's more that I want to have the possibiltiy to access all my data as a thin-client anywhere, anytime on any machine and still be on the safe side. I know that this is some kind of contradiction but what would be the best compromise? I know some questions may sound stupid but I really never had anything to do with servers at all in the past...

I need to install Trac on a server that's on a private development VLAN (no internet access). Obviously Trac needs to go out over the internet to download/install various things. Does anyone know of an RPM or tarball out there that I can use to install Trac without being connected to the net?

I have 2 different networks: the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping google.com on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7. I need your quick assistance about this issue.

I've got VPN setup and working on my server. I can VPN into the server and access my local network from anywhere. It uses pptpd for it. My problem is that I can't access the internet once I'm connected to my VPN. Is it possible to allow internet access through VPN?I mainly would just like to be able to connect, access my local network, and still browse the internet. Is there anything specific I need to change?

I have ubuntu server 10.04 installed with wired internet access through my router. I recently installed the ubuntu-desktop packages and cannot get internet through the gui, firefox never gets past the "looking up" stage.I can accessthe internet through the command line and through webmin httptunnel. Wget, apt-get install, apt-get update, apt-get upgrade all work fine from the command line. I have local access to the GUi as well in the form of VNC that is working fine.

I have ubuntu 10.04 running LAMP and proftpd, I can access over LAN but not when I type my domain name in. I have forwarded all necessary port to to the local ip of that box, added rules to ufw to allow traffic on those specific ports. I use dyndns for a second level domain and have used all their tools to check whether the ports are open and have the results I am looking for.

I am able to access phpmyadmin via my web browser using either my local ip followed by /phpmyadmin and by using the same layout with localhost. If i use my DNS name provided by no-ip which i bound to in apache2 i am able to get to the "It works!" page with the domain name but if i use /phpmyadmin after it, it will tell me that there is no such directory.

I've been searched for the related topic, but i couldn't found any of them. Basically, i want to set up a server to restrict internet access for other computer (windows box), but allow internet connection for kaspersky to download its database. Here are some questions:
1. Do i need two network card at the server box?
2. There are 8 computers but only 2 are allowed all internet connection, 6 of the rest are not allowed, all windows box can accept connection to download database from kaspersky.
3. Is it Iptables the best, easiest way to configure?

alright so i set up dhcp server and my clients are getting ip's, can ping each other, and can ping/ssh the server. but nowhere beyond that.
however if i ping an externel site, i get its IP addr, but no pings (100% loss)
im ripping my hair out over this. i know that iptables is right, but i dont know about dns
idk if this helps:
Code:
pavel@ubuntu-server:~$ cat /etc/network/interfaces
auto lo br0 eth0 eth1
iface lo inet loopback
#mapping hotplug
[Code].....

I must be very thick as i cannot seem to get my dhcp clients to connect to the Internet properly.
on my lucid server i installed dhcp3 server and bind9, i can ping and dig all on the local network. on the clients however, as soon as i go out of the local network there's messages like "unknown host www.google.com" or "network is unreachable".

I just finished setting up my small server, however I realized that no one can connect to it from the outside. The reason being is that my router is assigning internal ip's and dyndns is linked to that. I need port 80 for the Apache server, but if I have the router forward that port to my particular ip, won't it screw with everyone else's internet too?

Got a problem when I try to stream stuff off the net, such as watching ....., or listening to music clips.Basically, the internet just simply disconnects after a few seconds, or a minute at most after starting to stream - although it appears to be connected in the wireless icon thingymigig in the top right taskbar, eventually that goes though and says I'm disconnected.
While browsing normally, and using the net normally with messenger and looking throughwebsites,uploading/downloading via ftp, with no videos or music streaming, the net stays on - no problems.If I try to stream stuff from another computer running windoze 7, then these problems dont occur, the net doesn't disconnect and can stream till the end of time (or so it seems).Why does this happen just on the Linux machine?

I have a seperate partition for my "/home" folder. Whenever I install a new distro I format my "/" folder.
This way I was able to access my old home data files since I install using a different username. Everything worked fine until last Sunday.
10.10, unlike other versions of ubuntu, has encrypted my old username in my home folder.
Then using this document [url]
I was able to mount my hard drive again. But all the file and folder names are like this.
Btw I don't remember selecting an option to encrypt my old home directory in the first place, what is this ?

Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.

I have a machine (lets called it machine 1) with two networks card, eth0 and eth1. Both have static IPs. Once in a while the machine refuses to give access to the Internet via Firefox (eth0 is the route to router). Other machines on the network have no problems accessing the Internet. Eventually the machine would just magically start working again, but this time it just seems to have stayed broken. I've done some simple diagnostics and found:
a) I have another machine running Apache with a Wiki on our network - [URL]. Machine 1 is unable to connect to this Wiki. I get 'the connection has timed out'. I can ping 192.168.1.73 and it responds in the usual fashion.
b) If I try to ping www.google.com it times out with: ping: unknown host www.google.com. I can ping google using its IP address.
c) On machine 1 I have tried traceroute on both www.google.com and its IP and I just get:
1 * * *
2 * * *
And so on until hop 30. Doing this on any other machine on the network works. So while it seems I can ping internally in our network and outside, but when it attempts anything traceroute or URL related it does not work.

Noticed the statistic from the computer that it had taken 147MB from the internet today and put 8MB out. Why did it put out so much data, 8MB, why would it need to do that? It makes me paranoid.

i followed this guide, [URL] a few days ago and set up an sftp server no problem. The user can only see what is in there home folder which is only the examples file which is empty. Today i went to set up a 2nd ftp account for my own private use. I have it set up and all, followed exactly what he said the 2nd time around and my 2nd user is not chroot'd. I can explor the contents of the whole drive.
My fist user that works fine is "ftpuser" and the group is "sftponly" just like in the guide. My 2nd user is named "ftptaylor". Now i did have an ftp server set up with vsftpd where i had the same ftpuser account in a different group, but it was jailed to /home/ftpuser. I cant tell you how i did it, i followed a number of guides untill one worked. But could it be that the guide above does not in face jail the users, but just that my user was already jail'd?

I would like to accomplish: 1. Users to have access to their own Share on the server, no one exept the user shall be able to browse, read/write. (sould the user directories be in /home/<username> folder or shall one use another structure?
2. There shall be a public are where all users can browse, read and write. no guests, only users who have accounts!
3. A GroupShare. Users who are members of group Staff many browse, read/write.
4. Add some directorys for private use (to see how it works)
So would this be correct: Create the Directory Structure on the server:
Code:
# mkdir /usr/smbroot
# mkdir /usr/smbroot/users
# mkdir /usr/smbroot/public
# mkdir /usr/smbroot/groups/staff
# mkdir /usr/smbroot/private/fredrik_extended
or shall one use the default user shares /usr/<username>/?

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

I just installed ubuntu server on a spare pc I have and I plan on hosting forums on it. I don't want to install the gui on it and waste resources as the pc is not all that new. But I don't know how to download things into the pc and store them in folders through the CLI. I just want to know an easy way to at least download webmin into it and I think I can figure out the rest. I know how to install webmin from CLI.

I installed OpenSSH via tasksel and am using Webmin for administration. I'd like to be able to SSH externally and want to setup the necessary public/private keys to use in FileZilla. In Webmin, under Servers > SSH Server I can click 'Host Keys' and see an RSA key. Is this the public or private key for my server? Do I need to copy this into a text file to import it into FileZilla on my remote PC (that I want to connect from)? Is that all that needs to be done (aside from opening the port on my router/firewall)? Or, is there an automated way to set this up via Webmin?

At the moment we have one SSH server with the private key being on a usb flash drive, and the public key being on the server in authorized_keys2. Now that three more servers are coming online, should we generate new keys, so we have muliple private and public keys (one pair for each server), or use the same two keys to access all the servers

I have a virtual private server that I am trying to connect to using x11vnc. I ran this through ssh to setup gnome
sudo apt-get install gnome-core
sudo apt-get install gdm
sudo /etc/init.d/gdm start
sudo dpkg-reconfigure xserver-xorg
I later ran sudo apt-get install ubuntu-desktop to see if that would help.
Code:
#cat /etc/issue
Ubuntu 10.04.1 LTS
l
Code:
#sudo startx
Fatal server error:
xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory)
I assume this is because it probably doesn't have a video card.

a friend of mine is doing a small website-project in school (group of ~6 people). They want to use git as VCS and need acces to a server. I have an account on the server from university, but - of course - no root access.
I could create private/public keys for them, to SSH into my account, but I don't want them to have this power I found 'git-shell', which seems to be used for restricted access with git (although I'm not sure whether I understood the functionality).
My question is: Is it possible to configure SSH keys in that way, that the server runs them (and only them) in git-shell in a specified directory (using ~/.ssh/{config,authorized_keys})?
So that they can
- log in with their SSH key
- use git, execute scripts etc.
- use git push/pull from their private+school PC
- work only in a specific directory (like chroot) eg. ~/web-project/
