    Q: Network bandwidth monitoring? How?

    wiseindy Dec 23, 2014 at 4:12 PM | NETWORKING
    I'm looking for a network bandwidth monitoring solution that will help me do this:

    Show me my total internet bandwidth available (realtime).
    Which computers on the network are using how much % of this available internet bandwidth (realtime).
    (Bonus: Which applications on these computers are consuming the most bandwidth).
    I have searched far and wide but haven't found something like this. Does something like this exist right under my nose and I missed it?

    I have tried Spiceworks' bandwidth monitor plugin. It only shows me bandwidth usage of 4 devices at one time. Is there any way to view all network devices?

    Thanks!

    Q: Bandwith Monitoring

    ITR-dude Jan 4, 2015 at 5:18 PM | NETWORKING

    Hey All,

    I am interested right now in implementing a solution that will give me some on answers

    regarding who is hogging my network, with specific details, source IP and dest IP, port etc..

    The breakdown has to be on a host level in my domain, not just a global overview of my network, preferably agent-less solution

    and it has to be real time.

    Please give me you recommendations for such a solution

    Oh and.. yeah I got asa that can export netflow, and no, i'm not happy with that.

    Thank you.

    Q:Need to catch Torrent user

    maksim.avrukin Jan 27, 2015 at 8:01 AM | NETWORKING
    Hi

    we have a client that got notified by their ISP that their IP showed up with someone downloading illegal movies by using Utorrent. Problem is this is IP of their firewall, and there are 30 PCs behind it. Any recommendation on how to go about catching this person (This is not first time this happened but only happens twice a month or so. So we need some kind of Sniffer (don't mind paying for it as long its not ridiculous price) that records and alerts.

    thank you

    Q: Unable to access 1 site from local network

    by Nooch on Mar 5, 2015 at 6:38 AM

    Good afternoon all. I've been beating my head in all day on this, and just cannot figure out what is going on. A public website, externally hosted by godaddy, will not load up when connected to the local LAN right now. I can hit it from home, my cellphone, the library, even while simply walking into Mordor, but not from the office!

    Things we have checked:

    There is no domain name overlap (local domain name and website domain name are completely different)
    There are no DNS records on the local servers for this domain
    external site can be pinged and resolved successfully via command line while on internal LAN (and tracert and pathping are also good)
    Ran packet trace from gateway router/firewall (SonicWALL) and confirmed packets going out and coming back with no indication of a firewall rule being triggered
    reviewed firewall rules and no changes have been made
    Restarted DNS services on internal servers; no change
    Restarted DNS servers; no change
    Rebooted gateway router/firewall; no change
    Disabled AV on a local client; no change
    Everyone can surf to their hearts content anywhere else they want, but this one site is totally inaccessible. The site is our company website, so it would be nice to look at from time to time as edits get made.

    I'm probably overlooking something stupidly obvious here, and just can't see it due to vapor lock. Any brilliant ideas?

    Q: someone is sending email spam

    by Pesach on Mar 21, 2015 at 12:48 AM

    I think that I have a user who is inadvertently sending out spam. I keep getting put on the barracuda spam list.

    I have a sonicwall tz21, and I have capsa data analyzer (as well as spiceworks). Using these tools, is there a way that I can find who the rogue emailer is?

    thanks

    Ans:

    Don (SolarWinds) Mar 24, 2015 at 4:42 UTC

    You mentioned you already have Capsa. So, capture traffic before it hits the firewall and find out the IP addresses contributing the most on port 25 in outbound direction. If you see a device other than your email server, you most probably have found your culprit.

    If setting up Capsa before traffic hits the firewall is not possible, try any node like a switch through which all traffic must pass through. A switch lets you mirror all the traffic and helps make your Caspa analysis easier.

    Additionally:

    Provided you use an internal email server, block all traffic on port 25 and allow only your email server to send traffic via port 25. Now check the ACL hits on your firewall and find out which IPs were blocked by the ACL that blocked all traffic on port 25. Those could be the culprits.

    Also, block email relay - this will prevent infected hosts from sending out spam emails and ensure that only your mail server can send outbound emails (which is blocking email relay).

    Q: LAN bandwidth monitoring

    by Sunita Regmi on Apr 8, 2015 at 6:32 AM

    We have a situation in one office that due to very slow ADSL we are using 4G connection that has 25GB quota. All was going good until 2 weeks with everyday average of 500 to 700mb downloads. All of a sudden 2 days ago 11.5GB was consumed in 1 day and I could not figure out how. I have disabled all automatic updates, (windows and thirdparty) on the server an all 9 PCs, as I do it manually everyweek on weekend through ADSL. I logged in to each computer to see if there was any big file downloaded but all seemed normal. So I need to implement somethign that would monitor which pc has downloaded how much and what? is there something free/open source tools available?

    Thank you

    Ans:

    Todd_in_Nashville Apr 8, 2015 at 11:04 PM

    What you need is either Wireshark (free) or Colasoft Capsa (free trial version). Then configure a port mirror on the switch interface that connects to your internet facing router/firewall. This will show you all the traffic coming and going from your network to the internet.

    Both have built in graphical analysis tools to help you determine which IP address is using the most bandwidth and what protocols are in use.

    Capsa is more inherently graphical than Wireshark and fairly easy to set up and get started. Wireshark is considered the industry standard for network analysis, but has a fairly steep learning curve and can be a bit intimidating if you've never used it before.

    We are in the need of a good software package that will do both syslogs and traffic log retention. We do not want to spend $10,000 so if any one can suggest a good product that could do both that would be easy to setup.

    There's no doubt that a good network analyzing tool can help network administrator a lot. I think Colasoft Capsa is such a great tool.

    key Fearures
    • Real-time packet capture as well as the ability to save data transmitted over local networks, including wired network and wireless network like
      802.11a/b/g/n;
    • Monitor and save Internet e-mail and instant messaging traffic, helping identify security and confidential data handling violations;
    • Ability to Map the traffic, IP address, and MAC of each host on the network, allowing for easy identification of each host and the traffic that passes through each;
    • Identify "Top Talkers" by monitoring network bandwidth and usage by capturing data packets transmitted over the network and providing summary and decoding information about these packets;
      ...[Learn more from here]

    3 editions( Capsa Enterprise, Capsa Professional and Capsa Free) of Capsa can meet IT Pros' different needs. If you are still looking for a good network analyzer, why not give Colasoft Capsa A try?
    Q: Determining how much network traffic my servers use


    Avatar_user by Kendell on Apr 22, 2015 at 11:55 PM

    Hello,

    My company is facing the inevitable...our physical Server 2008 R2/HP DL380G6 servers are going EOL next year and I have to replace them because I can't get 24/7 4-Hour Onsite service after next April (I run a network for a 24/7/364 factory...I cannot be down.)

    The concept of moving to the cloud (Azure/Amazon/whatever) has been brought up. However, in order for me to size the plan we would need to have, I need to know how much data is actually transferred to and from my servers as that is a major component of the various pricing schemes.

    I've tried tracking using netstat -e, but something about my results don't look right...they look WAY too low. Can anybody recommend a good, ideally free, tool that could monitor my servers for a week or two and give me an idea of how big of a data plan I would need?

    I do have teamed NIC's in all servers, so that might throw a wrench in the gears.

    Thanks!

    Kendell
