Does anyone maybe know of a client app for Windows/Linux that polls the Linux (Ubuntu) Gateway and checks (in almost real-time) what the bandwidth usage is? Something like KInternet (which is SuSE only as far as I know) where you can see a graph showing how much kbps is sent and received per second.
View 11 RepliesI have a linux router box with ubuntu which routes internet for several people. There is no extra traffic shaping, so everybody can get the whole bandwidth when its free. What I would like to have is a real time traffic counter per ip, just like a program called "iptraf" but on a per-ip basis. Iptraf can only count on a per-connection basis and thus cannot display a bandwidth that a certain ip has taken (because a single ip can start several onnections). So a console program with text interface like iptraf would be perfect - does anybody know about such a program? After some googling I came to the conclusion that such a program does not exist (which must be wrong - i think that per-ip real time traffic flow information is the first thing every router owner would like to know).
View 2 Replies View RelatedWe have a production web site running apache 2.2.3 across several web servers. we also have a major problem with SPAM comments right now. our method of identifying valid IPs (whether by external clients/customers, or internal personnel) vs SPAM'ers is not ideal - its prone to erroneously labeling legit IP's as targets to be blacklisted.
What we need is.. a way to see how much distinct request traffic is coming from any given IP address to the site in real time (or very near realtime). Essentially we want to see in some graphic/chart way requests per sec to apache / per ip sorted by requests per sec.Would nTop do this? I've only used this in a limited form at a branch office, not on a production web server.
Is there any application (preferrably web) that can monitor in real time what is going on in my mail server?
Who is sending to who
Who is receiving
List of incoming/sent mail
Dovecot mailbox size
Monitor postfix queue
etc.
is there any software which can show us real time monitoring of ISA2006 usage(for example as we can see in WinGate software)

View 1 Replies View RelatedWe have something on our network that is reaking havoc with our content filter. I am trying to track it down, but so far I have been unsuccessful. We have approximately 500 devices in 100+ different locations spread across 9 states. Looking at each computer is not really feasible.
I need a machine that can sit in between our network and our internet connection and graphically monitor in real time and logs how much traffic each device is sending and receiving. It would need to sit inline so it has to have two nics and be able to pass traffic. The machine also needs to be transparent. Reconfiguration of our routers or workstations is not an option.
I have used ethereal and wireshark before. Ethereal may be a viable option, but wireshark seems to provide lots of information, but no practical way to make use of it. how to set up the box to be a transparent device on the network that will allow internet bound traffic to flow (freely)?
I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.

Code:
awk -F":" '$1 == "root" {print $3}' /etc/shadow
How can i convert this into the date/time of creation?
I am writing a shell script, which determines the OS installation date among other stuff, and i am assuming the root user's account creation date should be a pretty accurate pointer. Are there reasons why i should not be assuming so?I would be open to other suggestion for getting this date/time, but it would nevertheless be interesting to convert the unix time to "real" time without doing complex manual(or otherwise) computation..
While pretty, in a plaid way, my System Monitor screen is less than helpful. This started after I upgraded to 9.10 and applied more recent updates. From what I've read, the glitch is Radeon based. I have a Radeon 7000 card which itself has 32mb of ram, but I told my computer a couple years ago to think it had 128. I've tried the suggested short term fix in the linked thread (change the driver in /etc/X11/xorg.con to "vesa") but it didn't work.
I have two related requests: What can I try to solve the System Monitor glitch? How do I reset my settings back to knowing my video card's real capacity?
A few days ago, I did a clean install of Ubuntu 10.10 onto a Mac. I dual-installed with Mac OS, and everything appeared to be going very smoothly. until I connected to an external monitor (a video beamer I use in my classroom). This led to:
a) the external monitor apparently being considered the primary monitor, and
b) compiz effects being disabled.
I addressed (a) by modifying the file monitors.xml in [me]/.config. (Before that. I had created a startup entry xrandr --output LVDS1 --primary. That also seemed to work; after changing monitors.xml, however, I disabled that startup entry, as it now appeared redundant to me.) Generally and for all I can tell, my actual computer screen is now correctly identified as the primary monitor -- from the moment I log in, at least. The log-in screen itself, though, appears on the external monitor, or not at all when that monitor is turned off.
This is the content of my monitors.xml file: I have not found any solution for (b): when I physically unplug the external monitor and reboot, compiz will run again; but once I plug in the external monitor, it won't.

I've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.
