ssh bandwidth usage
location: ubuntuforums.com - date: December 23, 2008
I'm looking to find out how much bandwidth a "typical" ssh session uses. I'm curious to know if screen increases bandwidth usage or has no effect.
I'm considering various forms of satellite broadband, one option provides 2.4kbps so I'm trying to get a handle on whether I can use ssh over such a connection.
Can anyone suggest a method of monitoring the bandwidth usage of an individual program in real time? I found this (link), which might work, but I'd prefer something that monitored usage in real time if possible.
Some Nice Applications on Linux... (high bandwidth)
location: ubuntuforums.com - date: April 10, 2007
I have been using ubuntu for a couple of months now and whenever I google "linux application" I usually get the standard Apache, MySQL, Beryl you know the boring stuff... I hope to list some nice application for linux that deserves a mention as well, and hope others will add to the list.
Other apps list sites includes:
Linux is not boring
Very nice IDE for web development, looks better than jEdit for sure...
I follow this howto for installation:
(I recommend using the Eclipse addon instead, which is more stable)
Aqua Data Studio (http://www.aquafold.com)
Database Querry Tool I cannot live without...

Can Linux get a virus?
location: ubuntuforums.com - date: May 16, 2009
I have never gotten a virus with Linux, but is it possible? I know every machine has 0.1% or more of chance of getting a virus, but is linux near the 0.1%?

From windows, I can launch Xming to show login screen of linux box. However, after I enter the valid username and password, I simply get a another login screen. I never able to see the linux desktop. I can use
ssh to login linux box and launch any X program correctly though.
Please let me know where to fix. Thanks a lot!
How to get %CPU usage of a process
location: linuxquestions.com - date: June 4, 2003
I need to get %CPU usage of process , I tried following method on Redhat 7.3 Linux 2.4.18-3
1. read /proc/<PID>/stat (utime) entry and save in val1
2. read same /proc/<PID>/stat (utime) entry after 5 seconds and store in val2
3. calculate by using (val2 - val1) / 500 (since jiffies is 1/100 of second).
Does this make any sense.
But when I look at command output of ps -auxw, %CPU usage is about 50-60%(for eg) for daemons (i.e., <PID> above method).
This is a different value than I calculated using above method.
Please let me know
1. if above method is not correct, let me know correct method to calculate %CPU usage of process.
2. Is there any IOCTL calls to process management in Linux where i can get automated value of %CPU usage.
Thanks in Advance.
Get CPU usage as a %
location: ubuntuforums.com - date: March 22, 2006
I'm making a script to control some LEDs attached to my pc, I want them to serve as a kinda bar graph for CPU usage (four LEDs, so none for 0%, one for 25%, two for 50%, etc...).
However, the biggest problem I'm having right now is getting a script to see the CPU usage.
While it's easy to see using a GUI program, I've tried to get a script /C program to do so and failed..
/proc/loadavg doesn't seem to relate to the CPU usage, and while "ps -e -o pcpu" will show me a list of %s, I have no idea how I could add them together.
I've searched for any programs to do so and come up blank
So, does anyone know of any way I could have a BASH/Python script, or a C program, get the load avarage and output it as a %? Because I'm stumped
My bandwidth usage is berserk
location: ubuntuforums.com - date: January 3, 2011
A few days after I installed Ubuntu, I decided to use Evolution instead of Gmail (via the browser).
I have it set up to IMAP and don't have folder synchronisation on.
I'm saying this because I THINK Evolution might be destroying my bandwidth. But I hope I'm wrong.
My ISP says that I've used 9 gigs in four days. I've not done anything unusual or different to my usual activities (which hit 10 gigs in a month).
What could be happening here? What software - if any - could be eating bandwidth like this?
I don't have a wireless network either, and the ISP says that all the traffic is coming from my line alone.
I don't know Ubuntu well enough to know what could cause this (other than, say, someone illegally tapping into my physical line at the exchange).
Any advice / troubleshooting?
Utility for tracking cpu and bandwidth usage by process?
location: ubuntuforums.com - date: November 13, 2008
I'm sure there are a thousands apps that will track and graph cpu and bandwidth utilization by process--what I'm looking for are some recommendations of apps that can do this well and output data that can be easily read and manipulated for comparison and log it for later access.
Edit: I am NOT looking for just instantaneous bandwidth/cpu utilization.
Bandwidth usage Comcast
location: ubuntuforums.com - date: February 17, 2009
For my sins I am a Comcast customer
AS you may know they recently introduced a "fair usage" policy (don't get me started). Anyway, I am a "power" user but would probably never reach the 250gb limit they have set but I have know way of knowing as far as I can tell Comcast do not make their tracking information avaliable to their customers (am I right ?).
So my question is. How can I track my monthly usage ? My ideal vision is to have a small screenlet on my desktop that is just a running total of my bandwidth usage for the month !
Here is the challenge. My system consists of a motorola surfboard connected to a netgear WGT624v5 wireless router. Connected to that I have:
Roku Netflix box
Mythbuntu Media center
Webserver (mysql, apache, etc)
What is the simplest way to keep track of all that internet traffic ? I have looked into using the modem or router but neither appear to offer that functionality. Can anyone recomend ano
