General :: Finding A Traffic Monitor That Only Counts In A Specific Wireless Network
Jul 28, 2011
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 am on a slow Internet connection and it really makes me mad if something gets downloaded in background (like automatic update of any software) without my knowledge.
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..

I need to learn how to analyze network traffic for attacks and while finding the attack seems easy in my case I need to identify what hes doing. I will be happy right now if you guys can answer my question. How to identify if an attack has brought the server down? I have packet captures of an attack in progress and I noticed that every now and then the attacker would do something weird and the server would start sending packets with just the RST packet sent in response. Normally I had been seeing the RST ACK flags set or the FIN ACK bits set to terminate a connection. So once again my question is how do I tell if the traffic indicates a server crash?

what 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.

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?

I 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

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)?

If there is a command I can use to find specific file types? Say if I want to find all the jpg's in my home folder, but they don't have the .jpg extension in the name, how would I do it? Or can I set some kind of size parameter to find them? The ones I want are all from my digicam and roughly the same size.

I thought 'killall' would work, but I need to provide the "command" to kill. I'm really looking for a command that will kill all processes that have a particular file/directory open. Currently, my script fails on an 'umount' because there are several processes that have this filesystem open. The command 'lsof' is a good tool to determine which processes have a filesystem open, but I don't really want to write a script that parses through the 'lsof' output to capture PSIDs. Is there a linux command that can kill all processes that may have a particular filesystem open?

After installing 11.4, I need to type in the command to update the firmware for a broadcom wifi adapter. Then I needed to reboot, twice, before the system knew to use the adapter (where the adapter wifi light goes from orange to blue).
Then I needed to add my wireless network and type in my key. But the key does not take. If I click on my wireless network icon, it just re-asks for the key and does not connect nor give any other message. Network icon continues to display no connection.
So I need to reboot again.
When the system starts again, the adapter is blue, I click on the icon for my wifi network and it connects without asking for my key and I can then set to start my wifi by default.
Now my wifi works fine.

desktop has been running Ubuntu 10.10 just fine since December. Today, the connections menu shows nothing but "Wireless Networks: disconnected." My laptop is inches away and has a full connection.I'm not sure what diagnostic tools I have at my disposal. The one thing I've been able to do is lspci. The relevant output of sudo lspci -v | less is:
03:05.0 Network controller: RaLink RT2561/RT61 802.11g PCI
Subsystem: RaLink EW-7108PCg
Flags: bus master, slow devsel, latency 64, IRQ 20

Found about this website in vector linux site,you can check before you buy if the wireless adapter works with linux or not, so I think is a good tool to check wireless adapters by manufacturer, interface or chipset, it even have links to the drivers websites,

I got to establish an OpenVPN connection between two server and I have dhcpd on the client server which feeds a few SIP phones. All these phones are supposed to the register server through the tunnel.Here is the network structure:
Client CentOS:
eth0: 192.168.0.0/24
eth1:192.168.100.0/24
tun0:172.15.0.0/24
DHCPD: feeding above eth1 and all the phones with 192.168.100.0/24
If I ping 172.15.0.1 from the the Client CentOS it works all fine. Everything pings and I can even do SSH. However, the phones which obtain their ip through eth1 on the same server can not reach the 172.15.0.1. I think it's a route issue here. Can you please guide me to the right direction as to how to forward certain traffic through tun0 and leave the rest of the traffic to go through eth0?
I don't want to turn on IPTABLES as this is time consuming for me now and there is VPN setup. It has to do with setting up the routing but I am not sure.

I use a server with 3 nics,
eth0 192.168.2.100 (internal Web, Mail)
eth1 192.168.3.100 (Default Gateway nic for clients)
eth2 192.168.3.110 (should be default Gateway for all outgoing traffic not belonging to 192.168.2.100 and 192.168.3.100)
They are all on the same machine
i cannot set eth1 or eth2 as default gateway, as outside requests to eth0 would be handled in a false manner (somehow)
is there an easy iptables-rule to say, that outgoing traffic, not belonging to my networks can be redirected to a specific NIC (eth2)?

I want to check if traffic to a specific URL is being throttled by a hospital acting as an ISP. A client is having great trouble accessing a hosted web-app from inside the hospital, but access is fine from outside. The hospital IT dept are not interested as the rest of the Internet is fine. I need to trace where the latency is creeping in or where the throttling is happening, if I can do that, the hospital will remove it. Traffic is standard http to a specific URL.

I am running Debian Squeeze on an old pc (AMD K62-500) which serves as my multiwan router and torrent box. Internet uplink is provided via a dsl line and 2 wireless canopy modules.
Setup has been generally fine except when connecting/downloading as free user from sites like rapidshare, hotfile, filesonic, etc. The problem arises when I am connected to these sites using the wireless uplinks because of the shared public ip. I don't really download that much using direct download methods so I don't really see myself being a premium user from these sites.
If these sites are on a specific ip or ip range, an entry on the static routing table would have been fine but when I tried using ping, a different ip would appear to reply each time.
I wonder if there can be a solution like using iptables where in traffic to and from these sites will only use the NIC connected to the dsl line.

I'm hoping some of the Linux network experts can help me with this problem.
Situation: I have a technology which is a WebLogic JEE application that communicates to an Oracle database. Everything is installed in a single Linux virtual machine running in VirtualBox. Traffic from the JEE application goes via JDBC over TCP to the local running database. What I want to do is test a new database firewall server that wants all traffic destined for the database to flow via another virtual machine running the DB Firewall software.So therefore want I need to do is have DB traffic forced out over one interface only to return on another interface on the same VM listening on a different address.
JEE application running in WebLogic bound to 192.168.111.12 (eth1 a VirtualBox hostonly interface). Makes a request for 10.0.111.12 (eth2 a VirtualBox internal interface) which the database is listening on. Because both IPs are on local interfaces, Linux is going to handle the traffic and not route the 10.x traffic via the 192.x interface.I also have running the database firewall server which has a bridge (br0) between the HostOnly network and the Internal network.Both systems are running Oracle Enterprise Linux R5U4, which is basically the same as RedHat.What I want to do is have the request for 10.0.111.12 forced out via 192.168.111.12, bridged over the br0 connection and back into 10.0.111.12 and to the database. My networking knowledge is pretty good, but i'm stuck right now on the right way to do this. I'm pretty sure it is possible, I just need clear advice.
Reason for setup: Ideally I would build the system with the database on a separate machine so that I can easily route the traffic. Unfortunately we have many VirtualBox based demonstration systems with both the application and database installed on the same VM and therefore the amount of work to migrate these two dual VMs is going to be significant, also many of these VMs are demonstrated from laptops which have limited resources and creating a new database VM reduces overall performance. If I can create a way to force the traffic in this manner off and back onto the same VM via the other VM bridge, it would be fantastic.
