Ubuntu :: Control What Apps Can And Cannot Connect To Internet?
Jul 2, 2011
Using lsof I noticed that everytime I open some apps (like Rhythmbox or Banshee) it connects to the internet over ports 80 and 443. All I'm doing though is surveying my music collection. Why is it connecting to the internet for this? I don't have podcasts or album covers or any of that stuff set. In fact I turned all that stuff off.
the problem is that I only get so much bandwidth on my mobile broadband plan. I don't want apps connecting when I don't need them to. I played around with the UFW but it appears to only allow port configuration. I can't see how to control the connections of applications. I can't block ports 80 and 443 because then I'd shut down the web browser. How do Linux users control the internet connections of installed applications?

I feel little silly asking this, I accidently removed from my gnome panel my internet connection, volume control and battery indicator on F11. how can I add this back. It does not show up in the add to panel menu and the applications do not give you back the default feel.

I am running XBMC-standalone on a minimal Ubuntu installation and everything works as it should almost out of the box ... Now I would like to use my remote to navigate through ultrastardx which I start as an app(within XBMC).
I use linux-input-layer(devinput) with lirc(=necessary to make all buttons work).
So, if I start ultrastardx with the configuration from above my RC does not work at all but when I kill lircd before I start ultrastardx I ll get basic functions like Left, Right, Enter,... This is great but I miss two main functions Jumpto and search. To get them work and tremendously increasing the WAF I would need to send a key-sequence to ultrastardx.
What do I have to do to send such a sequence like "alt+j"?
Is there a way to kill lircd automatically before I start ultrastardy(at the moment I have to this manually )?

I have client workstations on separate intra-net LANs. Both intra-nets use network address translation (NAT) or masquerading on the LAN. The private network IP address should not matter (unless it does). When LAN-1 connects with an exterior web site, it will leave a record of the ISP public IP address. A LAN-2 connection could read this record, but how would it know how to reach into LAN-1? How can a network application running on a LAN-1 workstation find and connect with a network application running on a LAN-2 workstation? There is a utility called "woof" where one workstation presents a limited feature web browser for access by other hosts on the same LAN.

OK, so I have 2 computers with Ubuntu 10.04, when I VNC to the computer I want to control I get the first frame but no subsequent frames. However I can still control the computers mouse and action on anything I want to but I need to be in the same room to see the screen I am VNC'ing to, this sort of defeats the point of VNC as I would like to be able to control the computer from any room in the house.

On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.

After upgrading to Ubuntu 10.04, I'm not able to make any connection to the internet with either my netbook through WiFi or my computer on wired LAN. I can, however, ping my Solaris machines and Macbook. How do I fix this?

I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.

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.
[Code]....

I'm just about to set up my own home network here and I'd like to be able to control my Linux desktop over the network. VNC would be what I would normally use in this case, but the requirements are a bit different.
I basically need to be able to start work on something here on my desktop and continue that work seamlessly on a laptop or netbook as I'm moving around. I want to be able to literally pick up exactly where I left off and control my host computer's mouse pointer location, keyboard, etc and not have to open any windows: I need to be able to start from EXACTLY where I left off.

Ubuntu has a bug on VNC / desktop environment.
See the movies that I've made:
[url]
[url]
I set up the remote desktop on ubuntu and I connect to my current ubuntu's desktop with the VNC viewer. It is working, I see the mouse cursor, but I cannot see the files while I'm dragging them.
Another friend of mine has THE SAME problem.
I have installed and configurated NX server, and the problem is the same.
If I connect with the nx client, using a different session, I can control my desktop, I can drag windows and files, but if I'm using the shadow option from the nx client program, then I cannot drag windows and files.

I have a networked raid drive. Thecus 2100. Its running linux, and includes samba sharing. On that I have a folder shared. I can connect to and read and write from nautilus. No problems. However, I can't use other apps through that method. Its not really "mounting" that drive in the sense you'd normally think of (afaik).
If I try to mount the folder, no matter how I have tried so far (-t cifs, smbmount, etc), I can navigate the folders, but if I try to read any file I get a permission error. Looking at the permissions with 'ls -l', everything looks OK. The weird thing is, I can write a file, then read that file back as long as its the same session.
Just now I tried 'smbclient' with no special arguments. Just the server and path url. It asked for my password. Once I was in, I had no trouble getting files. I had a thread about this a while back and there were several links and all sorts of command line options to try, which I did, with no different outcome. I think its got to be something much simpler and more obvious. smbclient and nautilus seem to have no trouble. Anybody know what they're doing differently?

I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.
However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.
Here are some outputs:
I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.

I have a desktop, a laptop, & a wireless router. The router, unfortunately, doesn't support dd-wrt, tomato, etc firmware, but I would still like to prioritize voip/web browsing over bulk Internet traffic. I hope I can offload the router's missing QoS to my desktop.
Is it possible to have the laptop's connection go from the wall to the router to the desktop, where the desktop could perform the QoS of tomato, then continue on to the laptop? I'm a bit of a noob to networking (subnets?) but do well enough following good instructions.
As for the program that would do the QoS... Don't some Linux machines basically work as super-powered routers for businesses? So there must be some package but couldn't find one. The closest I got was wondershaper but it only shapes traffic for the computer on which it's installed; it might form part of the solution but falls short on its own. other devices should be able to access the Internet normally if the desktop is turned off, & work with other devices like a (jailbroken) iPod Touch.

I upgraded from 8.04 to 9.04, or something like that. I had the VNC server started, the one from synaptic manager, but after I completed the upgrade, did reboot to the server, and now when I connect (from my windows machine) with the VNC Viewer, and after I login with the password, I can ONLY view the linux, and I can't drag items, windows, etc. I can't do anything. One friend of mine had THE SAME problem, and I'm sure it's a bug. I have removed the VNC server from synaptic package manager, reinstalled it, and I got the same problem. I have downloaded the 9.04 Ubuntu linux, installed it on a temporary desktop PC, and it had THE SAME problem. Now (after 2 months) I have downloaded again the 9.04 version, from exact place, and the VNC server is working fine.
Now, my question is, how do I fix this problem on my current Ubuntu 9.04 linux server ? 'Cause if I reinstall the VNC server from synaptic manager, it will not change at all, I will still have this problem. Ofc, on the remote desktop preferences, it is selected "Allow other users to control your desktop". I dezactivated it, activated it again, still can't control the desktop, I can only view it.
Or, is there any other remote desktop program tht I can install to control my X on the linux server from my windows machine ? I don't need X to configure my server, but I need X 'cause I have YM and programs with GUI, torrents, etc.

I currently have two internet interfaces installed, one is ethernet (eth0) and the second is wireless (wlan0). Many command line applications allow you to specify which interface should be used, but many gui apps don't provide this option or at least I haven't found it. I have some questions:
1. How would I tell Firefox to use only my wlan0 interface? If it's possible in Firefox, is this also possible with Google Chrome?
2. If a program doesn't provide a command line argument to support this, is there a standalone application that could help manage preferences for multiple applications?

I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.
The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.
I'm using an wired connection to the router and have the server set up on an internal IP of 192.168.0.100. I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.
The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).
I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.
