Does anyone knows of any open source proxy/web traffic monitoring application so I can run reports on users web browsing for Linux? Something equivalent to websense? but free I'm not really concern about blocking any traffic only running reports.

We 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)?
Recommend open source tools that can help in figuring out if we are experiencing a network latency due to the newly installed firewall on our server.

View 9 Replies View RelatedI have a number of computers on a LAN. There are 3 laptops and 1 desktop, all running windows. I also have a Ubuntu server in the garage which servers up files to all those on the LAN. The server is not visible outside of the LAN for security reasons. Now, I want to track all traffic from any computer in my house that is coming and going in and out from the inter-tubes. I do not want to add this as a service to my current server as (a) it is behind the LAN and (b) I don't want to mess with security issues with that server.
I think I could set up a computer (an extra) which is between the modem and the router with two ethernet cards which would be able to monitor all traffic coming and going. This computer would, obviously, be exposed to all potential attacks as it wouldn't be behind the router's firewall. I'm not sure exactly how that would like or what software to use.
I've a server, and I want to drop all the traffic going out with other source port than 80 (apache) and 22(ssh). The reason is I want to prevent my machine sending packets I don't know (i.e. my server scanning networks or making DDOS attacks without my knowledge). The problem are the updates. If I do what I've said, the updates will not work. I want to allow updates, so I need to let DNS traffic (port 53) and the traffic of the updates to go out.
The problem is the source port. This traffic uses a dynamic port (I think like HTTP). Is there any way to specify a source port to do this? If a have a static port to do this, I would drop all the traffic going out with other port than 22,53,80 and this port.
I'm currently using a homemade Python script to parse script kiddie IP addresses from logfiles.To this point, I've simply been DROPping any requests from these IPs using iptables.I thought it might be fun to redirect their traffic back to them, but as I am not an expert at iptables, I was wondering if I should use FORWARD or PREROUTING.
View 7 Replies View RelatedWe all know we can install a linux system such as Fedora 10 and use it. Being linux, one should in principle get the source codes for everything that has been precompiled (except the proprietary drivers such as nvidia) in the installation DVDs/CDs. Where are the source codes ? Is there a place I can download them ?
To avoid confusion, I am not referring to the kernel source that can be compiled to give a linux kernel, but that does not include the drivers, such as intel_drv.so.
To be more specific, the intel graphic i810 driver has been built into any linux system, but where is the exact source? One answer may be that primary source intellinuxgraphics.com. However, if anyone tries to download the every changing (i.e., keep updated almost every single day) driver source codes from freedesktop.org, it is almost certain that the source codes will not be the same as the one that is finalized in Fedora 10.
What is the setup required in order for a 2 NIC machine to only forward traffic ?
I am planning to set up a machine between the LAN and Router like this:
LAN <--> machine <--> router <--> internet
This machine will only forward traffic. I will use it with ntop, squid, maybe snort
or maybe Untangle if I find it satisfactory.
Is my scenario fiable ?
I want to forward traffic, use ntop and squid on it.
Is there an easy way to monitor network traffic? I want to make sure my kids are surfing safe...
View 5 Replies View Relatedwhat I want to achieve is just to be able to say to who ever is killing our relatively fast connect that they aren't the only person using the network. Everyone just says "I hardly download anything." which is obviously untruthful as normally I can download at 1.5 MB/s but now loading even google.com takes way too long (same with pinging and all other sites). Once I do this, I can determine whether or not I need to call my ISP and do the long 'on hold' dance and "have you tried rebooting the router" BS.

View 5 Replies View RelatedRecently I notice that when I'm connected to an vpn server (pptpd) and I'm using it as a default gateway my download and upload speed decreases almost to the half of the usual speed. I made a test using iptables in order to count how much GRE packets are generated (except the real traffic itself) in that way:
Code:
iptables -I INPUT -p gre -j ACCEPT
iptables -I OUTPUT -p gre -j ACCEPT
iptables -I FORWARD -s 172.16.10.101 -j ACCEPT
iptables -I FORWARD -d 172.16.10.101 -j ACCEPT
The first 2 rules match all GRE packets between the pptpd server and client, and the next rules - the traffic between the server and the client.
When I turn the counters to zero and begin to generate traffic (to browse, to download etc.) I see that the GRE packets are even more than these in the FORWARD chain.
So, my question is first of all is my test correct and is it true that so much gre traffic is being generated during the browsing (it becames clear that the traffic is double than if the pptpd wasn't used as a gateway) and if yes - can that traffic be reduced?
Is there a nice easy to use tool that displays (in KB/s) the internet traffic from every IP on a network?
Currently I'm using iptraf, but it's very hard to understand at times.
A little info on my network:
I'm using SNAT for internet sharing.
I have two Linux processes communicating via a nameless pipe. How can monitor the traffic in the pipe? How can I inject data into the pipe? I have root access and know the pipe inode.

How can I monitor my network traffic sorted according to the "which binary file is using how much"? I can find the total transfer rate in "System Monitor" in Gnome, but what if I want to find for individual process. There are softwares like netmonitor in Windows, but how can I achieve that in UBUNTU LINUX.
GUI application will be nice, command line software will also be fine..
Ubuntu system monitor applet doesn't show internet traffic although my wireless is working just fine. I use a conky to monitor bandwidth through vnstat and had no problem till I upgraded to maverick.

I'm simply trying to make a little restriction on www packets under two rules:
1. Allow inbound/outbound www packets (works!)
2. DROP inbound traffic to port 80 from source ports less than 1024. (DOES NOT WORK!)
Now, technically, when i use hping to test my rules, hping3 192.168.100.100 -S -p80 -s 1023 I should NOT receive any packets. However, i still receive packets, which means my rule that says less than 1024 does not work. (see below)
And this is my iptables rules in shell-script so far:
#!/bin/sh
DEFAULT_NIC=eth0
SERVER_IP="192.168.100.100"
ALLOWED_WWW_PORT=80
IPT="/sbin/iptables"
[Code].....
I have a 2 machine LAN with both machines having an ethernet card and a wireless card. There is a Netgear router, both eth and WiFi, allowing both machines to access the internet.
On my Linux machine I am looking for some software that allows me to keep track of my broadband usage on that machine, excluding traffic between the two machines.
There are numerous such programmes for this in XP, which use Winpcap and a GUI frontend. The "other" machine on my LAN is XP and uses just such a program.
Is there a graphic tool that can monitor the traffic over a USB port?
ie like system monitor for network traffic but over a specific port?
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 1 Replies View RelatedI am connected to a network with free traffic inside it and post-paid outer traffic. So I need a way to be able to separately monitor the download traffic from inside and outside the network. All the solutions I`ve found for now offer monitoring of ALL up/down traffic.
So, I want to get separate statistics on these:
1 — 81.89.188.0/23, 217.197.9.0/24
2. — 81.89.186.0/23
3. — 81.89.178.0/23
4. — 81.89.176.0/23
5. — 81.89.180.0/24
9. — 217.197.12.0/24
[Code]...
UPD: I`m connected to the internet through the network`s gate, so all the traffic comes through eth0. I wish to separate traffic incoming from the IPs on top from all other traffic
is there a utility with which I can get the current traffice towards a given host, for example;
command 87.255.33.32

I need a simple traffic monitor for Linux, that counts the traffic in a specific wireless network because I have volume restrictions on that one.I tried it using the following iptables rule:
[code]...
iptables -m mac -A INPUT -p all --mac-source <mac-address> ! -s 10.0.0.0/8
where <mac-address> is the router's one. 10.0.0.0/8 is the local subnet. What I actually want is something like --routed-through <mac-address>. Also, is there some way to gather iptables's statistics? Or is there maybe another tool that does what I want (reliable)?
I would like to be able to monitor which programs are allowed to access the internet, but a search for programs to do this has turned up nothing. Preferably, I would like a notification to come up every time an application uses the internet. Is there any (n00b friendly) software available to do that?
View 2 Replies View RelatedI'm looking for a powerful network traffic monitor that can do all of the following (or at least a combination of tools that can do the following):
Tell me how much data was downloaded/uploaded on an interface this month and the previous month tell me how the traffic was used throughout the monthshow which internal IPs (IPs in the 192.168.1.0/24 network) used how much traffic show which ports/protocols on those IPs used all that traffic
Hhow LIVE traffic flow statistics that can tell me total speed of traffic going through an interface as well asshow which internal IPs (IPs in the 192.168.1.0/24 network) are using how much of the traffic show which ports/protocols on those IPs are using that traffic
This tool will run on a linux router through which all my internal PCs are connected to the Internet. This means the tool(s) need to work with NAT (traffic being forwarded and not necessarily destined for the interfaced being monitored).
The distribution being run doesn't have a package manager so any packages or dependencies have to be manually compiled and SCPed over file by file. For this reason, the tool/tools need to be simple (things like vnstat, not things like ntop that have their own web interface).
I know that vnstat can tell me the first bullet point so it's only there incase there's a tool out there that can do everything. If there's a tool that can only do the second or third bullet point, that's great too - I'll just keep using vnstat and look for something else to do the other task.
I can not seem to find a pdf viewer browser plugin other than the actual craprobat plugin from Adobe. The default Ubuntu install comes with a perfectly good open source stand alone pdf viewer, but this means that the browser has to save it to your download directory then run the external viewer, and eventually your download directory is all cluttered up. I would much rather just view the pdf in the browser.Is there no open source browser plugin?
