Ubuntu :: Any Command Line Tools That Can Tell What Process Is Using Ethernet Port?
Jul 14, 2011
The download bar on my conky overlay (${downspeedgraph eth0}) seems to be maxed out constantly. This is when everything should be idle with no downloads happening in the background (at least non that I know about).Are there any command line tools that can tell me what process is using my ethernet port?
I want to run OpenBox on a netbook. For those of you not familiar, it is a very simple window manager, where I can launch a terminal with a mouse click, and I can start the few apps that I need from the command line. Basically, I am trading eye candy and easy access to a lot of stuff I don't need for a more responsive GUI.
My question is...what package should I install, and what corresponding command line would be used to launch a tool to manage the wireless LAN connection?
I am using Redhat cluster suite. I am trying to configure cluster on linux using command line tools. I have following queries. Please answer them as early as possible.
1.Can I add node in cluster without adding fence device using command line tool? If yes then how?
2.I want to add failover domain in cluster. How can I add it using command line tool?
3.I want to add resources in cluster. How can I add it using command line tool?
4.I want to define services in cluster. How can I define them using command line tool?
Does anyone know of any good command line audio editing tools? I would like one that can take an mp3 file and crop everything but the first 30 seconds or so (possibly decompressing those 30 seconds as well).
I did a command-line installation. I dont have an ethernet connection, only wireless. For some reason the alternate installer doesnt install "wireless-tools" How do i install it? At this point I am thinking of booting off a live USB, downloading the wireless-tolls package from here Save it to a folder in the command line installation where?) then boot back into command line and install from there But I am not that savvy with command lines, and dont know where to install to...
1) capturing an RDF formatted RSS feed as a file on my computer
2) converting the result to HTML using local command line tools
I've sorted 1) with wget? I've discovered xsltproc but I'm going round in circles. The master plan is to import my pinboard bookmarks into a static web site produced on my linux box using a handful of clever bash scripts.
I'm hoping to find an existing Linux tool for measuring latency:
I'm trying to diagnose how much latency my OS and NIC card are adding to TCP latency in Linux. I looked at the following tools but all (at least at the surface level) measured bandwidth (Mbps/sec) rather than latency (nanoseconds for transmition of 1 packet of size x).
If I were to write a custom test, it would likely do the following:
Client:
Create a fake message of the specified length with some padding for an incrementing identifier. Open a TCP connection (with the right parameters like TCP_NODELAY, etc) Loop and send messages containing an incrementing identifier. Store the current system time (in nanos) associated with the identifier. Listen for responses, record the current time and record the latency of that identifier asynchronously Server Listen for a connection Echo back any message received
Assuming both boxes had the same setup (configs, cards, OS, CPU, etc), are relatively close to eachother in the network, and one knows roughly the network's latency contribution, one could get a rough estimate of the OS + NIC contribution and begin testing various configurations.
One could also get a more accurate picture of the latency by using a network sniffer and snooping on the lines between the two hosts, calculating the latency between the two sides for an ID, and then subtracting that from the internally measured latency.
I've spent a lot of time googling on this one, but could not really find anything that would convert HTML to images. Does anyone know if there are some command line tools that can do this? I need to convert simple HTML documents to images to be attached to Powerpoint presentations. Could firefox gecko be tapped into to do this without a GUI?
I am looking for free and well known fax command line tools for receiving and sending faxes I wan it to save receive faxes in pdf format with file name included with caller phone number and date of receive:

I installed ubuntu 10.10 server from an usb stick. I do not have access to a wired connection and do not have a CD drive, so now I need to configure the wireless connection.for that I need to have wireless-tools which if i am not wrong are not installed by default so the question is: how can I install the wireless-tools package from an usb using only command line? note: I got internet access from another ubuntu-desktop PC so i can download any package needed, etc.
I have created three child process from one parent. And different child has different functions. Child 2 has got function to load file called "wc" to count file1 and and its required to get their files by command line arguments. I can get the files through command line but couldn't get the files when child 2 process start.
The GUI for network configuration of Fedora is marvellous such that the configuration is almost fool-proof. But how can I make the connection by hand in the command line mode? It goes okay except the very last step. When I disconnect the eth0 interface from the right-hand side of the desktop GUI, I tested how to bring it back by command line but I failed. When disconnected, the ifconfig still shows the eth0 interface, with just the ip address portion changed.
I tried "ifconfig eth0 192.168.1.xx" to give it an ip address but the connection is still down even if the ifconfig shows an ip address for the eth0 interface. Then I tried "/etc/init.d/network restart" and "ifup eth0" and also "route add defaut gw 192.168.1.1" but none of these could accomplish the same work as a single click on the GUI to connect. I am very curious about how to do it in the terminal.
I would like to Close/Open port 21 using command line. I have an FTP server and I don't want to have the port open all the time. I need only two hours by week to be open port 21 from outside to inside.So I need to know the command line for opening and closing the port 21 then I will implement this in a script into cron.hourly.
i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.
pardon me if i am not making absolute sense here as my knowledge is limited on Layer 1 and layer 2.
I want to pass ip address,port address and some parameters from command line using python script.The ip address and port address for establishing socket connection and remaining parameters to execute different connection.
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
I have all of these "archival" email messages and attachments. Most are Mozilla Thunderbird format. Others are Evolution format. Some are win-dose. Most are linux. Where can I find software that will me format, organize, store, and retrieve email messages for long term archives? I'd like to collect all of each thread together with any of the relevant attachments. I'd like something that is searchable. I'd like something that is "pretty print-able" -- PDF or similar -- should I want to share an historical thread with others. I suspect there are commercial-grade, "compliance oriented" application suites for message and document storage.
I have a third party program (tightvnc) which I want to monitor and detect if it loses a connection with a client. I don't care if the client has the program open but isn't doing anything with it, I only want to know if the actual TCP connection is lost.
Since TCP takes forever to die on it's own I was thinking the best way to detect if a connection is lost is by bandwidth the bandwidth on the tcp port allocated to the VNC connection. Are there any tools built in to redhat (RHEL 5.2) which I could use to do this? Since I don't have full control of the operating system I would prefer to use built in tools rather then trying to get a new tool installed.
I've some file with .sh extensions that runs some softwares.Now,how do I stop running that filesI know we run the command ./start_tomcat.sh to start the apache.Is there any command to stop that file/process or is it just kill the process to stop the process
I have a program which requires running on port eth0. My current connection is named eth7. how can I change this? I went to /etc/network/interfaces but did not see the connections for eth0 or eth7 in that location. I also tried to change it in the "Network Manager" but that just broke my connection and returned errors. What Can I do?
I keep on getting intermittent ethernet failures using a Gigabyte GA-MA790FXT-UD5P 790FX motherboard with a built-in network card. This is a problem on all operating systems.After many intermittent failures I think I've finally found the solution; turn the PSU off, wait until the CMOS light goes off (about 15 seconds), then turn the PSU back on. It appears a bug with Linux where a setting on the firmware of the network card is occasionally incorrectly modified causing it to malfunction, when power is removed from the device the setting resets to default and normal functionality is restored.
I am running 11.04 on a Dell Inspiron 1501 (the first gen.). I was using my Ethernet port to connect to the internet until about two weeks ago - suddenly the system no longer recognised that port even existed and just kicked me offline. I am able to get online now with a wireless card (replaced the broadcom card, that was a whole different can of worms...).
why my system is unable to connect with the Ethernet port? If I plug in the cable nothing happens.
