General :: Internet Gateway Monitoring - Log Bandwidth And Site Access

Sep 27, 2010

In one of our network we are using one firewall which works as gateway. All machines are able to access internet through this gateway. There is no filtering and any internet restriction. I would like to setup monitoring system which monitor and log bandwidth and sites access by client machine. Is there any tool which monitor internet access as well as sites which are access from client machines.

Networking :: Control Bandwidth Access With Squid - Allow Certain IPs To Have Higher Bandwidth Access?

May 27, 2009

We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.

Fedora Networking :: Cannot Access Internet Through Gateway

Sep 4, 2009

I have installed fedora 11 64 bit on a new computer. I have no problems accessing the computers on my local network, but can not get past the gateway. The gateway is running windows XP with IP address 192.168.0.1 and is named "internet". When I boot the new computer in windows, there is no problem. Here is the output of some commands I saw in other posts with similar problems:

$ /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:24:8C:7F:10:0C
inet addr:192.168.0.245 Bcast:192.168.0.255 Mask:255.255.255.0

Server :: Slow Access To Web Site Using Squid And Internet Explorer.

Apr 4, 2010

Slow access to web site using squid and Internet explorer.I am trying to troubleshoot an issue I am stuck on. We have a website that is loading .htm documents extremely slow when using Internet Explorer 8 behind Squid. When we bypass the proxy and go directly out to the internet all is fast and pages load fine.But when the proxy is on documents will take sometimes up to 6 minutes to load.This issue is only apparent using Internet explorer 8.I do not see the issue when using firefox with Squid.I have tried to use the no_cache directive thinking it may have been the cache but that didn't work either.I am attaching our access.log, store.log and squid.conf.

Ubuntu :: Bandwidth Monitoring Per IP?

Jan 5, 2011

My problem is the following : I have a certain Internet connection for a certain network. So many people are sharing this network. What i need is a software on Linux (preferably Ubuntu) that will enable me to monitor the bandwidth usage PER IP Like : ip x.x.x.x using 20Kb upload 200Kb download , connected to this site for example.. The main goal is to know from which IP is the high Upload traffic or download traffic is coming , because i have a certain quota and I'm always getting over the quota (in upload and download) and end up paying extra for the ISP , so i would need to know who is using lots of upload/download bandwidth .

Ubuntu Networking :: Dialup Modem Computer As Internet Sharing Gateway To Wireless Access?

Mar 4, 2011

I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.

Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.

My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.

Code:
lancer@lancer-desktop:~$ ping www.google.com
PING www.l.google.com (74.125.237.17) 56(84) bytes of data.
64 bytes from 74.125.237.17: icmp_req=1 ttl=55 time=179 ms
64 bytes from 74.125.237.17: icmp_req=2 ttl=55 time=176 ms
64 bytes from 74.125.237.17: icmp_req=3 ttl=55 time=158 ms

[Code]...

What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)

Ubuntu Networking :: Monitoring Bandwidth Usage On Lan?

Jul 6, 2011

Since 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.

Networking :: Bandwidth Monitoring Per Local User?

Mar 17, 2010

I have a Linux host connected via LAN to Internet. No proxy or squid is used on the host and outgoing traffic to Internet is not limited. I have several local users on this box. Recently bandwidth statistics on the switch/router showed increase in the Internet traffic from this host. How do I monitor the traffic utilization per local user on Linux host? I want to be able to monitor the amount of traffic per port and per user, like user alice downloaded 20GB today via port 22, and so on. Do not offer to use Squid, this is not just web traffic I want to monirot but all amount of incoming/outgoing traffic per user per port.

Debian :: Network Bandwidth Usage Monitoring Application?

Jun 7, 2010

I 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.

Networking :: Bandwidth Monitoring - Log Based On Usage / Consumption?

May 10, 2009

Can you suggest bandwidth monitoring software for GUN/Linux that will log bandwidth based on usage/consumption.

Not options:
- slurm or any other "real time" bandwidth monitoring
- /sbin/ifconfig <interface> | grep "RX bytes" or the like

What do you use to monitor your monthly, daily, hourly bandwidth consumption (assuming that you do).

Ubuntu Networking :: Monitoring Networked Computers Bandwidth Usage?

Mar 25, 2011

Back in school I remember using an application that would identify active IP addresses on a network, and basically show you a log of activity. We actually monitored another lab and went in and showed them what we saw (all the machines had IP addresses on the monitors.) We could see websites, bandwidth, etc.

I'm trying to find an application that would do this again. I've been trying to monitor my networks to see what machines are performing unauthorized operations. ISP is showing high bandwidth usage and there is no way checking email and browsing is using this amount, 200GB a month! Something is going on here.

Software :: Virtual Host Bandwidth Usage Monitoring Apache

Mar 11, 2010

I've got an apache server running several virtual hosts. I have them separated by domain name, and they all come into the same IP address. I'm looking for a way to monitor the bandwidth that they use. The only feature that I'm really looking for is a breakdown of which domain is dishing out how much bandwidth.

blocks.com got three visitors this month. And spent 200kb in serving them.
emus.net got fifteen. And spent 1mb in serving them.
reverse.org got 4000. and spent 400mb in serving them.What I would like to see is a report, could be a web page could be a file. Ideally with graphs. Showing:
1.
2.....
3[400mb worth of dots]

1-blocks.com
2-emus.net
3-reverse.org

I don't need it to show me how many visitors or from where or anything like that. I am just looking for a side by side comparison of how much bandwidth each domain is using.Is there some application for this or something. Everything that I've found has been for information on a single site (awstat and friends can show me information for multiple sites, but as far as I know it won't show me information comparing them) I haven't found anything for nagios, but perhaps there is something out there for it, or a sneaky way to make a nice plugin that would do this.

Ubuntu Networking :: Bandwidth Monitor Which Performs Constant Monitoring Of The Ethernet?

I want a bandwidth monitor which performs constant monitoring of the ethernet. I want to see how much bandwidth I am spending by opening each website, downloading, etc. A small program which can remain "always on top".

I am using Gkrellm but the problem is it does not updates itself constantly, I mean I have to close/open its eth0 monitoring window to view changes (I am not talking about restarting Gkrellm, only the bandwidth window which shows the daily, monthly bandwidths)

Networking :: Tools For Monitoring Network Bandwidth Usage Of Program/port?

Dec 8, 2010

I 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.

There are a lot of boxes in this network and we have intranet site. If I connect computer directly to the network with everything set to automatic. I can see this intranet site. But I've installed a switch. One box has two net adapters and it takes internet, intranet and all from one adapter, the other adapter is connected to switch. Now, I have connected to this switch two computers. Internet is working fine. But I cannot get to this intranet site from these boxes. I can get into shares of other computers in the network but they cannot see me. Everything is hidden behind the gateway. But that's not the problem for me. All I want is to get to this intranet website. How can I do it?.

General :: Monitoring Internet Connection Speed?

Jul 30, 2010

Quote:

I'm trying to find a good host for my site, and I've been trying to get one with a fast, reliable connection - I frequently use it as a proxy server for various areas, and since my connection is frequently a 50 Mb or 100 Mb line, I need a fast network connection so it doesn't slow down too much when I switch to the proxy server.

At the moment, I've narrowed it down to a couple of providers that are all within a few hops and <6ms away from my main location; it pretty much comes down to connection speed. One in particular that I'm trialing offers an metered 100100 connection at a good price, so I'm hoping to go with them, but I want to make sure the connection is solid and doesn't drop to a much lower speed during the day if they are sharing it among many users.

I have a pretty simple speed test procedure - I use wget on a 1GB file hosted on a backbone with a 1GB connection, and see how fast it downloads. For now, it's sticking at a steady 11.2 MBs or 90 Mbs, which is fast enough for me, but I need to make sure it can maintain that speed even in times of heavy usage.

[/BACKSTORY]

Basically, I need a script that runs wget every half hour and logs the output and time in a reasonably readable format. It's probably something simple enough to do, but I'm just learning my way around the linux command shell, so some simple instructions on how to create and run such a script would be great [CentOS 5]. I have full root access to the server and I'm the only user on it if it matters.
