My wireless usb network adapter is constantly using ~100bytes/s even when there is nothing I can think of that needs to talk to the internet. Is there a way to find out what programs are using the internet?
We are switching from an uncapped 512kb line to a 4MB line at the office... One catch though. The 4MB line will only be linked to a 30GB account, without the option to top up. I therefore have been asked to put something in place to regulate what the staff download at work. Basically block movie, music and torrent downloads should be sufficient, but they would also like to have a list of where staff have been in case of abuse. I have tried OpenDNS in the past, but the guys took great delight in getting around this, and did it within minutes... I can't enter a proxy setting into their browsers, because they all have local admin rights on their Windows boxes and will just disable that. How do I do this on a server level, so that they can't get around this?
I setup a server with vmware esxi 4. I installed opensuse 11.2 and I have successfully setup an internet gateway and I manually configured (static) my client IP. My question is, is there any software or commands that I could use to manage the bandwidth usage for each client? eg. only 5Mbps for 192.168.1.5, 10Mbps for 192.168.1.10, etc
I wrote a program that multiplies 2 matrices using multi-threads and another one using multiple processes and shared memory. Both in C.I need to find the total memory usage of these programs. I know of the top command, but when my matrices are relatively small they don't even show up on top because they complete so fast, how can I find the memory usage for these instances?Also, how can I find the total turnaround time of my programs?
Top only show the memory usage for individual processes. Apache often runs hundreds of processes, each of which may use only a small amount of memory, however the total memory consumed by all apache processes can be fairly large.Is there a way to see the total memory usage for all apache processes?
On Linux Mint (Gnome) i used to go to Network drive. that is on the right hand side of Nautilus there is a short cut for Network. in there i could see my network hard drive and other laptops connected to the network, and i could access my files. but on OpenSuse, when i open the network folder, nothing comes up. may be it needs some sort of configuration.
I have installed oracle enterprise Linux in my desktop.It is the free download from Sergio's blog(in 6 CD)Now i need to work with the yum in oel5 for installing packages and also i need to install the necessary packages in my client another system both are in a network.
recently my server become a little slow and lazy, so I started a small investigation what's going on and found out, that there is some problem with network.All processes which uses network are able to use 99% of CPU time when they got any requests. First time i thought it's only a bad configured Apache but after some research I found even FTP or SSH does it if they have to do something more (for example getting data to another server using rsync).So far I wasn't able to find a cause of this. No new software installed, only updated every few days. I have another server which have the same config, same software, same hardware and is updated in same days. But this one works without any problem. I think it's probably hardware (LAN) leaving me to it's creator. Is there some way how can I test if it's really LAN or just something bad happened to the system?
Also there is another issue - maximum speed dropped down to 20-30kB/s for both download or upload.It's Debian Lenny 2.6.22-6 if you need to know.
A small "mom and pop" WISP would like to provide account usage information to customers.Basically, when a person connecting to the WISP's web site is a customer with an IP address from within the WISP's subnets, a link would appear on the web page where customers could read total bandwidth usage (daily, weekly, monthly, and yearly totals and averages) and public IP address. Information could include the top five bandwidth URLs visited; graphs or charts of usage; and usage during specific periods, such as business hours (8AM-5PM), evening hours (5PM-10PM), night (10PM-8AM), and weekends (10PM Friday-8AM Monday).
The WISP has installed cricket (http://cricket.sourceforge.net) and rrdtool (http://oss.oetiker.ch/rrdtool). The next trick is to grab and format the data for customers.I'm not looking for answers like "look at xyz package." Helpful responses will include a rudimentary outline to solve the problem. That is, "xyz package" might indeed be what the WISP needs, but some guidance how to use xyz is needed to move down the road.I have no experience with this type of thing. I appreciate responses from people who are experienced.
I was wondering how do you slap a packet analyzer like Wireshark somewhere between all the computers in a house and the router, so you can tell what websites are being accessed? I mean websites, specifically. I'm not trying to monitor bittorrent, IRC or other things yet - I'll get to that later. I just want to break this insanely complex task into smaller bites for now.Also, since my ISP has bandwidth caps but does not have a means for consumers to monitor total network usage, I'd like to figure out how to use Wireshark to do that as well. This, I am assuming, is easier when wireshark is running on the pipeline going into the router.
I am trying to figure out why the remote X performance of our RedHat 5.3 system is so bad. We have tried using X (Gnome session) from several different X Servers (Windows Xceed, Windows XWinPro, Linux Xnest - both Fedora 11 and Centos 5.3 and Mac OS Xnest) and the system is barely usable. I have monitored the network traffic on the RHEL system and it goes up to 6MB/s at some points, which seems a bit too high for X net traffic?I have disabled ipv6 and any ip_tables modules and that has helped a bit, but it's still not very good.I suspected the network hardware and driver, but I cannot see how that would cause network traffic problems.I wonder if there are any X Server network settings I might check, or whether trying XFCE would be a better option over Gnome. If so, do I have get the xfce group from a CentOS Repo, or is there something better suited to RHEL?
I just wanted to use a network bandwidth usage monitoring application. Scenario: I am using an EV-DO based USB broadband modem with a limited GB plan. For additional data usage they charge per MB. Currently I use either wvdial (mostly) or pon to start the connection. So if there is any network monitoring application which could log time used and data used for the session, it would be great. Actually debian has too many different network monitoring applications, But I am not sure which one suits well for this purpose.
I have looked for and found several tools to show a system's total network usage. I have not, however, been able to find any that show this information in the context of individual processes. Do any such tools for linux exist?
I have a network connection between 3 computers sharing the same net bandwidth with the same router (modem), I wanted to know how much every one of this network taking from the bandwidth, I want an easy program like switch-sniffer (see the pic) to scan the network and tell me how much every one taking from this network in real time.
I'm currently running my own postfix server which is the MX for my domain. This is hosted in my house at the moment on the end of an ADSL line with a static IP. However, I'm trying to go totally mobile so I can kill the ADSL and the line rental and switch to 3G. Does anyone know a solution which allows me to accept (or ask for delivery) of SMTP when temporarily connected and queues it externally? Sort of like a hosted mail queue which pumps SMTP onto my laptop only when I ask it to.
I have a home PC which connects through internet via a Zyxel ADSL router. I use Fedora 14 as my one and only operating system and sometimes I am seeing the LEDs of my modem blinking very fast which means that something is downloading. I want to know which application download what on my PC. Is there any tool in Fedora that can show which application uses my network?
I'm running Ubuntu 10.04 and all was well on my home network until a household member decided to get a laptop and jump on my network. All he does is watch videos on ....., download crap from P2P sites, and maybe even watch p0rn. Is there something I can use to control this or maybe set my router to give him the minimum resources available? Also, I want to block him from downloading junk from P2P sites or places he might get a virus. I'm on a D-Link DGL 4500 Router.
I've run into a problem gathering usage for my xen virtual systems. With my old model I used to gather all network usage via my cisco devices using the the counters for each port. Each system had it's own port on the switch, and I tracked network usage accordingly. Now that I'm using xen for virtual systems, and multiple vm's share the same switch port, i'm not exactly sure what my best option is for tracking usage.
I thought I may be able to setup vlans on the switch, and bind each vm to a different vlan using vconfig... but it seems like there has to be a better solution than that.
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.
Cannot activate network device eth0!"device eth0 does not seem to be present, delaying initialization".i cannot find my network card while i set up network configuration Now I use dual boot window 7 and fedora 9,I cannot find my network card in select network adapter while network configuration ,i have a network card Atheros AR8132 PCI-E fast Ethernet controller NDIS(620)and for wired in Accer laptop .
I need applet which shows the total data usage (In+out) (of the current session or since the uptime) on the panel.I searched a lot, but everytime I had to click somewhere to see my data usage. I don't want that. I want my data usage displayed regularly on the panel.
the data usage information from the carrier is often several hours old and is accessed in some arcane ways (logging into their website, sending a specific SMS message at best). Here's my idea: single-session data usage is perfectly reported by ifconfig ppp0. The problem is, how tokeep track of previous sessions accumulate the numbers rollover to zero at specified date To be able to do this across computers means that one needs to store it on the modem/SIM card itself. (As a specially crafted SMS message, or a contact).
