Huge problem...please help!

Posted:
in macOS edited January 2014
I use my MBP at work everyday, yesterday I went into work and connected to the network like any other day. After a few minutes my network administrator came in my office and started freaking out asking if I was downloading anything. I said no, and he went back to his office only to come back again and say my internet activity was extremely high, so high it was slowing down the entire network. I went the rest of the day without connecting to the network, but I need this problem resolved. What the hell could it be? I really dont understand how out of no where my computer is doing this. Any help, suggestions, advice on how to fix this problem, or figure out what the hell it is?

    Most likely its b/c you are signed into your .mac account under system preferences -> internet and network.



    I see massive traffic in our PIX firewalls whenever I am signed in from my IP address. Sign out of that if you are logged in and ask him to check the logs. If that doesn't help post back.

    First, it is virtually impossible for a single computer to bring a whole network to its knees. That said, you have given us absolutely no useful information. That fact is that the network administrator went ape when you plugged-in does not count. Rather than unplugging, you need to offer to help the administrator diagnose the problem. The only time that I have ever heard of anything similar to this was when a student working with me installed BitTorrent on a Windows machine.

    I do have Azureus installed, but I don't use it at work. It doesn't make any sense. I just plugged it in again and he came running over. He's telling me it could be virus related, I really dont know at this point. How do I check to see what kind of traffic my computer is calling for? What can I do to see what the problem is?



    When he came over I was emailing someone with 2 images attached, but I HIGHLY doubt that is what caused the problem.

    Easiest way to monitor all your packets and traffic is to load a tool like ethereal

    ill download that now I guess and give it a shot. What would be a normal packet rate? If you just sending email, and searching for stock photos?

    Hard to say really. I use solarwinds in a vm for network traffic monitoring.



    I'll load ethereal on my MBP and see.......

    Have you downloaded 10.5.4 yet? If you have Software Update set to download in the background, maybe it was downloading the update when you were plugged into the network.

    well i just downloaded Net Monitor and loaded it up and went along with stuff I do day to day. It looks like its Mail.app causing the problem. Every time I load it up the it goes nuts. It doesn't really make sense though. How can Mail.app take so much bandwidth? Could it really be the two images it's trying to send?

    What kind of accounts do you have? IMAP, POP? Some companies block IMAP ports. Also check your Outbox and see if your Mail is trying to send something else out.

    Just what sort of bandwidth are you talking here? Use Activity Monitor and click network tab to find out. How big are the images you're trying to email? You really do need to give us some simple information like this in order for us to help. Does for instance, the network activity last longer than required to email the images?

    I use gmail, IMAP and mail.app. For some reason when I'm not sending anything the Activity Monitor is showing uploading and downloading even if I close everything else out.

    The files were both 19MBs each, and I was trying to send them in two separate emails. The network activity does last longer then the sending of the emails. After its done syncing, for some reason it is still uploading and downloading, and it doesn't stop.

    Hmm, gmail has an attachment limit of 20MB. This might have something to do with it. When the SMTP server rejects it Mail will go screwy for a long time before it can give you the error.

    Yeah, the problem has now stopped and I can leave Mail.app open again. It must of been part of the problem. That's really strange that it happens. Thanks for the info.

    Trust me, I know your frustration. The wife likes to send out videos through email to her mother once in a while and we use gmail. I learned that lesson a while ago.
