Fedora Networking :: Determine Which Programs Access Internet
Mar 16, 2009
I see from the netspeed applet that my computer is downloading stuff almost constantly. Not a whole lot, 8b - 700b per second while apparently doing nothing. Some of this is just responding to broadcasts from the router, but surely not all. I would like to be able to determine which programs are accessing the internet over that wireless card, with a view to cutting down on my bandwidth usage. Is there a program that can tell me which ones are doing what at a given time?

I have used other distros on and off in the past with no trouble, but for some reason I seem to have had this problem with several versions and flavours of Ubuntu on various systems. I've never solved this problem the previous times I've had it, just given up. But this time I actually need to get this working. I've recently upgraded my computer, so my old system has been relegated to HTPC duties in my lounge. I installed Ubuntu 10.04 and I'm having issues getting internet access with some programs, while others work fine.
Firefox and Evolution haven't been able to access the internet from the start.Empathy IM has no trouble connecting to my MSN and Facebook accounts.I had no trouble downloading and installing Google Chromium browser through Ubuntu Software Center, and have no trouble accessing the internet with Chromium.On the first boot after the install, Ubuntu automatically told me to update my nVidia drivers online, and did so without error.Update Manager detects updates, but fails to download them.
I successfully and flawlessly downloaded installed XBMC Media Center and some related skins and things through Synaptic, but XBMC cannot access the internet. However it can access shared files over my LAN, including Windows 7 shares.Ubuntu itself cannot access any files on my Windows 7 computer. It can access the work group and see my Win7 shares, but refuses to mount them. Strangely, XBMC can access these shares and stream media from them fine.

What distro is the easiest for a new person to get started? I also need wireless internet access. I've tried to do this once before with linux (mandriva as I recall, I gave up)before and had problems installing the programs that would allow that. Also are there Linux versions that I could install on my pocket PC?

I would like to be able to monitor which programs are allowed to access the internet, but a search for programs to do this has turned up nothing. Preferably, I would like a notification to come up every time an application uses the internet. Is there any (n00b friendly) software available to do that?

I have installed fedora 11 64 bit on a new computer. I have no problems accessing the computers on my local network, but can not get past the gateway. The gateway is running windows XP with IP address 192.168.0.1 and is named "internet". When I boot the new computer in windows, there is no problem. Here is the output of some commands I saw in other posts with similar problems:
$ /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:24:8C:7F:10:0C
inet addr:192.168.0.245 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::224:8cff:fe7f:100c/64 Scope:Link

I installed Fedora 13 on my laptop today after deleting a badly screwed up Windows XP partition. Everything installed smoothly even my Broadcom drivers but I can't seem to figure out how to get Firefox to access the web with a URL.
I can ping Google, and can get to it in Firefox if I use the IP address from the ping, but going to [url] in Firefox will give me an error message about not being able to find the server at the web address. I was also able to update from the terminal with yum update just fine. I've tried searching Google for some answers, and maybe I just can't phrase my query right, but I found nothing that I could use to try and fix my problem.
I've attached a HardInfo report which I hope could be useful if you need to know what my hardware is (an HP Pavilion zv5000 laptop).

I've installed Fedora 13 on a Toshiba Satellite A40 laptop, and am trying to get the wired ethernet connection to work. Network Manager says it is connected, and the connection details (DHCP assigned IP, gateway, dns servers) all seem correct. However, I cannot browse the internet. Checking for updates fails also. I have tried pinging various sites and the results are inconsistent - sometimes it works, sometimes it times out with "unknown host". [URL]... I've searched around for similar issues and tried disbaling ipv6 both in Fedora and Firefox, but this doesn't help either.

After upgrading to F14 from F10, we seem to have access to the internet from our console, and no one is able to connect to server as well. We have static IP from comcast. And all the configurations on the eth0 looks fine. We are able to browse, if we set the server to dynamic ip. Also, we are able to connect another PC (laptop) with the static ip configuration, and browse fine. Read through many messages on this forum, cant get any clues,

I have a work network of about 20 boxes most of which are running Windows 7 and one of them is a file server using linux and another is Windows server 2003. Now the local IP is distributed by the router, and no regulation of internet access is done by any of the servers.What I need to do is restrict internet access to select domains, which would probably need DHCP through linux(I think, not really sure), and I need something simple like a 'blabla.conf' file with the allowed websites that I can edit. need to know how to regulate IP addresses through the linux box (all details if possible, I never tried to do that before), and how to restrict internet access also through linux.

I'm interested in figuring out which programs on my machine are using swap, and how much each is using. I realize this can probably be done with top, but I am having trouble figuring how how.
What I've tried:
Start top
Press f (add column)
Press p (SWAP colum)
This adds a SWAP column, but the data doesn't seem to be correct. Top lists Firefox as using 582m of swap, but the header simultaneously reports that 0k of swap is being used.
Is there a better way to monitor swap usage?

I am building a CarPC which I'd like to have wireless internet access on. I have Verizon phone service so if there is a Verizon air card (not wireless card, an air card so I can have constant access without having to search for hot spots) that would work with Fedora 10 I would be very happy. I don't really know where to start and I can't find too much on Google, so I'm just looking for what options are available.

Fedora 11 is completely unable to access the internet for some reason, and after some troubleshooting, I've determined the problem to my Motorola 2210 DSL modem. I know my connection is working fine, as it works perfectly in both Vista and 7. I've tried things such as grep 'Ethernet' /var/log/dmesg, filling in the information into the network settings manually, to no avail.

I tried to preupgrade to f14 and cancel it after some time. Now, I am facing a problem that I cannot access internet from mobile broadband; but I can access net while i am connected via ethernet or wireless. I have cleared preupgrade files with
Quote: yum clean all; yum remove @preupgrade
$ uname -rs Linux 2.6.34.7-56.fc13.i686.PAE
It can detect my HUawei modem and creating an IP as well. But no Internet. Can you tell me the reason?

I am coming from Windows XP Pro, on the same machine (and where I am writing this post from) so the internet clearly works on XP. On F13, the eth0 connection is activated and the drivers for the NIC chip were installed with the OS. The NIC is Intel Pro/100 VE. The problem that occurs is that the system updater (in GNOME) can access the internet, and installed a bunch of updates after installing the OS. I know it can get to the internet because the updates worked and in the System Monitor, I can see both uploading and downloading occurring during the updates. Now the problem is that when I open FF, I can't seem to get to pages, and I get the usual FF error (pic -- [URL]). However, I CAN get to [URL] as well as [URL] , but I cannot access several other subdomains on fedoraproject.org . I also cannot get to any other page online, ([URL] for example).

I have a wired lan at home with 2 XP boxes connecting to a router to a DSL modem. I want to network my laptop, running only fedora os, for file sharing, printing and internet access. I will be using the laptop probably exclusively for creating/maintaining a Drupal-based (LAMP) e-commerce site to replace our old one for our small family business.

I am behind NAT using private IPs like 172.x.x.x in my lab. I need to access programs from other machines which are also behind NAT. What is the syntax of ssh command that i can run? Because when i make connection within one LAN for example:ssh -X 172.x.x.10 to 172.x.x.3 it works fine. I can access programs like gedit, firefox etc. But when i try to do the same on the machine that are behind NAT then i get this error;
[root@localhost ~]# gedit

I'm having problems with programs connecting to the internet. I typed in
sudo apt-get install wine
and I get the following:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package wine
I KNOW there is a package called wine but it cant find it. I can't install any other programs from programs either. My gDebi package manager is supposed to automatically download and install dependencies but it doesn't do that either.
I am sure I am connected to the internet as I can browse just fine.

I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

I have F11 running on an MSI wind. I installed KDE and then downloaded LXDE and have been using it for a few days. All of the sudden LXDE panel and a program called GTK-gnash started eating up all my cpu. So, I stopped the processes and restarted the desktop via CTL-ALT_BACKSPACE and rebooted. Now I cant open anything in the fedora menu, no programs, nothing comes up. Cant find any info on what I should do. Can still run firefox and stuff from applets, just cant access my programs menu.
