I'm using Ubuntu 9.10. My internet connection is an ADSL which I have set up using "pppoeconf". The connection starts at boot up. I can also start it if needed by using "sudo pon dsl-provider" and can stop it by using "poff dsl-provider".Recently I noticed that when I start my computer, there is some program (or programs) which is connecting automatically to the internet and downloading and uploading a lot of data. The data transferred can exceed 200 mb or 300 mb in an hour. I don't know what is being uploaded or downloaded.I know for sure that no file sharing programs like bittorrent clients are started at bootup so it is strange that this much data to be downloaded and uploaded without me sharing files or downloading files explicitly. The update software also does not run by default as I have opted to start it manually.
Is there any application which shows the programs that are connected to any particular port and transmitting and receiving data?In Windows XP I use a program called "What's Running" which clearly lists the programs using the different ports in the local machine and the remote IP addresses that the program is connected to. It also shows which program is transmitting and receiving data at any point in time. Is there any similar program for Linux?My internet connection is a data limited package otherwise I probably would not have bothered.

In Ubuntu, How can you tell if your connection is being monitored? Have a home system, me and girlfriend are only users. Lately ALLl websites are taking longer to download. She claims her system and bank accounts were compromised. So am wondering if the connection is being monitored. Lots of tools for "windows" to help determine, but what about linux / ubuntu?

freshly installed Debian-netinst, configured internet connection. Pinged Google - all transmitted packets were received, 0% loss.
Yet I am not sure if I have internet connection for what ever package I am trying to install using apt-get install package_name, I receive
E: Unable to locate package package_name
How can I check internet connection from CLI?

So I just installed ubuntu from a net install, and updated from the internet and posted on this site through firefox while installing vlc wich just froze at 90%.....
but when I try to add community repos it comes up with errors. And while running a system check it says I have no internet connection...
I'm connected through ethernet on a router wich works with the g5 in the other room running osx, and the pc upstairs running ubuntu meerkat. Now I had this same problem with SUSE 11.1 and worked around it by adding through terminal but I was never able to add from the GUI.

I had clicked on the upgrade notification in Update Manager. After 3 hours of downloading, it stopped abruptly. Now when I try, I get a message saying could not download, check internet connection. I am able to visit other sites, and am actually downloading the CD itself without any problem.

I recently decided that I want to install mplayer on fedora 13. Problem is, everytime I try, a new problem arises. I've tried add/remove software, and it said "package download failed, check internet connection" which doesn't make sense because I'm connected to the internet and my connection is fine. So, then I tried yum install mplayer, that gave me an error.

There is this active connection in firestarter: ec2-174-129-193-12.compute-1.amazonaws.com (Port 443 - Service HTTPS - program python)After doing ps aux | grep PID it shows: /usr/bin/python /usr/lib/ubuntuone-client/ubuntuone-syncdaemon...This comes up in the firewall in each login, how do I get rid of it and how did it get there in the first place? Another question is if there is a way to limit a program's access to the internet. For example KCalender.. The things I type up in there may be stored somewhere. How can I disable complete access to the internet for that program and any other program so they can't backup, share, check etc. ?

I would like to know if there's a way of checking which program has new updates without internet connection?
Maybe like having a program to grab the currently available programs from a repo?

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

I'm not talking about like:
apt-get check
I mean it's like, and I thought it was this:
valgrind <application>
Needs:
x
y
z
Does anyone know what I'm talking about? A lot of programs I'm getting segmentation faults like Rhythmbox, a few games, etc. so I dunno.
EDIT: gdb kind of works, but doesn't show me what another program would..

It is most certainly my fault but I am now without a sound volume control and it does not show up in the add to panel.What can I do here? Does your icon have code that that I can use or can I find the file somewhere and create a link? Alsa mixer works ok and nothing is muted and I have sound so as to play music. The Internet connection and the power connection icons also don't appear.

I have a Ubuntu box with a ftp service on. I wanto to upload/download files from my Win XP connected via LAN. I tried ftp command from cmd but I received "Error 530. Login incorrect. Login failed".I'm using root, I am 100% sure about the password (I managed to connect via putty), I just wonder how I can check the ftp connection from xp to ubuntu... maybe a firewall is blocking the port 21?I also tried ftp command in ubuntu (when I was connected with putty) and I got "connection refused" error.

I would like to have all traffic from the ethernet connection out through the wireless (basically using the box as a router) however I am having some trouble doing this.
I have done this before on Windows however I am having some trouble doing this on linux, I have tried using Squid Proxy however I am having some trouble using configuring/using it.
I am using Yellow Dog Linux however I am willing to change to any other distro as long as it is compatable with PS3 (as this is what im using linux on)

I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.

OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.
It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.

I want to check whether a USB is plugged in its slot from a C program. I want to make use of /proc interface for the same. During my reading i found that /proc/bus/usb/devices will tell how many USB devices are currently present.
So whether i can open this file and use stat call to identify whether the size is 0. If size is 0, i can assume no USB present. Else i can assume USB is present.
Whether my understanding correct. If USB inserted, how can i check the folders present in the USB stick.
