Networking :: Record Tx/Rx Bw In A Program - Without Using Tools From /proc/net/
Feb 22, 2011
I need to record Tx/Rx bw in my c program at defined intervals. I am aware that there a bunch of available tools but I need a minimal version with only Tx/Rx bw with no other details. I have tried the tool bwm-ng which mostly serves my purpose but either it runs continuously in the console or saves result in html file. It does not have any options to save the result in txt file which could have been easy to parse.
Is there any other simple way to record Tx/Rx bw in a program?(without using tools from /proc/net/ or any) I am using Mandriva Linux 2.6.31.5.

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 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.

I've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.

Is there a way I can start a program and then record a log of how much memory it's using at a specific interval until the program ends?
I've tried writing a shell script but get the error: ./apps/mem-test.sh: line 4: [: too many arguments
Here's the non-working script:
Code:
$HOME/apps/ImageMagick/bin/convert -limit memory 64 -limit map 128 $HOME/SSI/davidkennardphotography/Img-Orig/95-Pole-Bank.jpg -set option:filter:filter Lanczos -set option:filter:blur 0.8 -resize 1024x720 $HOME/resizedImage.jpg &
GOODY="ps -p $! -o pid,%cpu,rss,cmd | grep convert >>test.txt"
[Code]....

I was running 9.04 and could, through some magical sequence of toggling options that I was unable to figure out, occasionally get recording from the mic to work in audacity. Ardour worked more reliably, but is kind of over-featured. Audacity is simpler and I know how to get things done. For a while, I was doing basic recording in Ardour, saving it to wav then editing in audacity.
Well, I noticed a howto on getting audacity working in 9.10... so I upgraded ("what could possibly go wrong?"). I still can't record audio in audacity and ardour is now ALSO unable to record audio. They start recording samples but nothing comes in but silence. I've got audacity set to ALSA/default/default and when I click monitor, the stream appears in the pavucontrol app. I've moved it to the input device and that doesn't seem to affect the results at all. Everything looks like it should be working fine except there's some invisible mute button, or something. Under alsamixer's Capture section, Mic has a red "CAPTUR" with no bar to adjust.

I want to record a line-in source Using the Audacity program. but the wave trace in the app is not symmetrical about the zero axis. This is not what I would have expected and I wonder if it will show up as poor quality recordings when I transfer to my hifi.

Have a television card on the computer. Works perfectly well and it would be nice to use the computer as a television program recorder. Buggering about with a DVD recorder is a lot of trouble. How is it possible to do this - surely pretty basic - job? Buggered if I know. It is important to compress the thing into *.avi format or something like that. Otherwise it takes up a huge amount of space.

I am trying to read the /proc/net/tcp6 file of a huge server (chat server) for monitoring the tcp6 connection states.
This tcp6 file has more than 26000 lines. For monitoring the server connections, my monitoring tool has to read the /proc/net/tcp6 file quickly in regular interval. Presently it takes minimum 6-7 seconds for reading the whole file.
My tool can able to read the normal file (26,000 lines) less than 1 second, but it is not possible to read the same size of proc file.
I have 2 questions:
1) Why proc file takes more read time than normal file?
2) Is there any way to read the /proc/net/tcp6 file more quickly?

I'm trying to find out what is the difference between wifi0 and ath0 (atheros wifi card) in terms of packet counters shown in proc/net/dev pseudofile. The fact is that wifi0 and ath0 packet counters are different. I've read that wifi0 refers to the physical device and ath0 refers to virtual device over wifi0, so, as far as I know, packets counters in both devices should be the same, isn't it? Another annoying question for me is that ath0 doesn't show any erroneous packets, while wifi0 does.

I did this --> [url]
My computer says the driver is installed and the device is present. All of that went fine. Now I need to connect my card to my house's wireless network. Am I supposed to do that in System-->Administration-->Network Tools? The problem is that whenever I click on network tools, the application looks like it is going to start-up and then quits/crashes/runs away, whatever. Any ideas on what is causing this?
Okay, I tried launching from the terminal, here is what I got:

Is there some software to measure Internet speed and show where the slowest element is?
I use OpenSuse 11.1 and KDE although Im happy to set up a user using Gnome.
Just recently my browsing speed dropped to almost nothing ...I used [url] to measure my speed and it gave a very slow result 30kb/sec ....usually its around 3000kb/sec. I rang my ISP's helpdesk and they told me my ADSL connection was fine. Two minutes later it was back to normal!
I know the internet speed varies from time to time ...I guess depending on how many are using it and for what. But..I suspect that my ISP was restricting my speed and Im looking for a tool that will tell me which part of the internet is the "slowest"
I would also welcome pointers to information about internet speed and what causes it to change.

I don't know if the title is a correct description of the problem I have. I registered a domain name in godaddy, created a subdomain name and pointed it to some name servers. After some time, I moved my website so I change the name servers of this subdomain name. But the problem now is it is still pointing to the old name servers. Everytime I visit the website in my computer, I get errors. But I try it in another computer, I works. So I suspect there is something left in my computer that still tells my browser to go for the old name server. I've cleared cache and temporary files of this browser but it still does not change.
