View 3 Replies View Relatedrecently 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.

View 5 Replies View RelatedI'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.

View 3 Replies View RelatedI'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.
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?
View 2 Replies View RelatedI 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.
application to monitor application wise network usage?
View 3 Replies View RelatedI 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?
View 1 Replies View RelatedI 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.

View 3 Replies View RelatedI'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.
View 2 Replies View RelatedWe 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've had a stable system for a couple of years now, and it just ran out of space.

View 2 Replies View RelatedSince this is my number 1 place for asking questions, I figured I would go here first. So I live in New Zealand where good internet doesn't exist yet, and I'm in a flat with 3 other people and we get 40gb a month which hasn't been lasting more than 2 weeks. It is somewhat of a mystery where all our data has gone, so I need a way to monitor usage. We use a variety of operating systems including linux, xp & windows 7 on my pc, and xbox 360. Is there any kind of integrated solution I can use to monitor everything with password protection so it can't be disabled? I have tried looking in the router, but it doesn't give me many statistics, and I think it combines lan with wan usage. At this stage I don't have the money to make a linux box to put between the router and the switch that can monitor everything, but if it comes to it, I will shell out for one.
