Show HN: My network connection monitor for Mac
- bahman2000 15y agoI'm on Lion. Installed the app, launched, window comes up but connections are not listed. Restarted the computer. Connections are still not listed. Reinstalled as per FAQ. Still not working. Am I doing something wrong?
- aparadja 15y agoNo connections come up even if you let the window stay open for a while? Could you run "kextstat" on the terminal and see if "com.radiosilenceapp.nke.PrivateEye" is listed?
- Udo 15y agoIt works for me. Thanks for making this, keep up the good work! Now if you introduce the option of blocking applications, I'd uninstall LittleSnitch for this.
- aparadja 15y agoThanks! You can use Radio Silence to block apps. It's on the same domain, and linked in the sidebar and header.
- Udo 15y agoGreat, I just bought it. Any chance of incorporating Private Eye into Radio Silence, at least for the purpose of selecting the apps I want to block? Or being able to drag and drop an app from Private Eye into Radio Silence would be enough. It's just that selecting those apps is really painful from the file dialog, especially if they're obnoxious system services like helpd.
- aparadja 15y agoYou're the second person to suggest that today. It's a great idea, and I'll implement it as soon as I can. Radio Silence already supports drag & drop. You can drag apps into its window, if you don't like the file dialog. Private Eye doesn't yet support dragging stuff out of it.
- bahman2000 15y agoYes Not listed
- aparadja 15y agoThat is very strange. Did you move the app to a different folder after installation, or something like that? Also, it might be better to swith to email to debug this. I'm available at contact@radiosilenceapp.com
- shad0wfax 15y agoFirstly, this looks very interesting and from the screenshots seems very impressive. It doesn't work for me as well (Macbook / Lion 10.7.1). I DON'T see "com.radiosilenceapp.nke.PrivateEye" listed as well. I haven't moved the app to a different folder. Do let us know if this is resolved.

- aparadja 15y agoThe problem seems to be about kernel architecture compatibility. I'm going through the build settings etc to see if there's some reason this happens. I'll keep this thread updated.
- aparadja 15y agoUpdate: The problem was related to 32 vs 64 bit kernels, and is fixed now. I also received an email confirmation from everyone who reported the issue that it works for them. Thanks!
- aphrax 15y agoI'm getting this issue of no connections showing..reinstall didn't help... any ideas? Thanks. edit: second reinstall seemed to fix it..
- nclrhombre 15y agoI like the minimalism of this, just a connection monitor, nothing else. Great work! 1 feature request tough: I've installed RadioSilence also, and it would be very handy to be able to drag&drop apps from PrivateEye to RadioSilence to be silenced. Lack of this doesn't stop me from using this, but would make life a bit easier.
- aparadja 15y agoClever, thanks! Radio Silence already supports drag & drop. Hadn't thought about the option to drag apps out of Private Eye. This just landed on my todo list.
- FredBrach 15y agoPrivate-Eye sounds like a good entry for Tractup: http://www.tractup.com http://www.tractup.com a site for early product traction. :s
- aparadja 15y agoTractup doesn't support dashes in the url :).
- FredBrach 15y agoThis post seems to not have been appreciated by all. I understand and I apologize for the inconvenience. It have never been my intention to abuse of this method. I will not do it again. Thx.
- hmottestad 15y agoWhy is the whole thing a big flash application?
- elemeno 15y agoVery nice looking program - can certainly see myself using it to keep track of what's going on on my Mac. One thing I've noticed though, is that it doesn't seem to be catching network activity that's taking place from the command line. I'm running an SSH session, and just tried pinging a server from the terminal and it didn't see either of those. If you can add that as well, then it would be even more useful.
- aparadja 15y agoIt should notice command line ssh connections (it only logs new connections, not already established ones). Pings aren't really connections, so it doesn't list them. I understand that it's not perhaps the best choice for it to act this way. Putting this into consideration.
- ovi256 15y agoIt's probably using some high-level Cocoa network framework, and not kernel-level functionality like netstat does. So my guess is only apps using the same high-level net framework are listed.
- aparadja 15y agoActually, it does use kernel-level connection tracking.
- borism 15y agowhy Lion-only then?
- aparadja 15y agoBecause of the user interface. It's a dumb issue, but Lion changed the way table views work. Getting from 0 to MVP was about twice as fast with the new Lion features. It's something I consider improving, though. Fundamentally, the same app should work on 10.6 too.
- oscardelben 15y agoThanks for sharing! Any chance you share the source on Github?
- aparadja 15y agoMy plan is to give the software away for free, but keep the distribution somewhat centralized and the source closed. The app is, on a business level, a marketing tool for my Radio Silence firewall. I hope it will drive traffic and links to the site by giving away a complementary product for free. Sharing the source through github might work against that goal.
- masklinn 15y ago2 questions: 1. Why distribute as a pkg instead of a zipped .app or a dmg? 2. Why not put it on MAS? edit: scratch that, I found the postflight script installing a kext.
- bcl 15y agoOr it might help you reach that goal. Opening up some of your source will give your more advanced customers more confidence in your coding abilities.
- aparadja 15y agoThe open source approach surely has its benefits. However, I think/guess/believe the free closed-source app has more direct effects on my visitor traffic. Open sourcing the software would probably help me build some kind of personal branding, but it's not a goal I'm actively working for right now. Currently, my priority is to get radiosilenceapp.com more visibility and authority.
- pepijndevos 15y agoJava network traffic isn't listed. I tried both Minecraft and the Clojure REPL. Nothing. It would also be useful to see the type of connection, TCP/UDP, port number, etc.
- aparadja 15y agoThanks for the info. I'll look into the Java issue. Wonder if they do something unorthodox with their traffic. The connection details is something I've pondered about. Port numbers, at least, might be useful. At some point, the user is better served by wireshark anyway. Drawing the line isn't a trivial problem. Any suggestions are appreciated.
- 46Bit 15y agoLooks awesome - exactly what I've been after to be honest. I'd love you if you could make it work on 10.6 as well...
- sirn 15y agoNice looking app! But why distributing it as PKG when it only creates Private Eye.app and com.radiosilenceapp.nke.PrivateEye.plist?
- aparadja 15y agoIt has to install the plist to /Library and launch the kext after installation. I'm not sure if that can be done just by sharing an .app bundle.
- sirn 15y agoHow did VMware Fusion 4 do it though? They just distributed the whole VM as a single .app, with all kexts loads/unload dynamically on launch.
- aparadja 15y agoGood question. I honestly have no idea. The kext has to be owned by root:wheel for the system to accept it. Making a pkg installer was the simplest solution I knew of. Out of curiosity: is there a downside to pkg's?
- vril8 15y agoVMware launches a sudo script to do it's deeds ..
- tychobrahe 15y agoI believe smcfancontrol installs its kext by demand from inside the Cocoa App. I don't know how it's done (I only do UNIX stuff on my Mac =/) but I believe it changes the .kext owner and invokes kextload. You can 'sudo' from inside a Cocoa App by using AuthorizationExecuteWithPrivileges: http://michaelobrien.info/blog/2009/07/authorizationexecutewithprivileges-a-simple-example/ http://michaelobrien.info/blog/2009/07/authorizationexecutew... About PKGs: I think that they're okay, but, historically, they're maligned for being "black boxes" that install files all over your system. App files, OTOH, are (99% of the time) clean, live on /Applications, and sometimes use ~/Library.
- doe88 15y agoOn Lion there is also a new useful shell command called nettop.
- CyrilMazur 15y agoToo bad it doesn't want to work on my Snow Leopard system
- ra 15y agoI agree... Any reason why you don't want to support Snow Leopard?
- aparadja 15y agoI would love to support Snow Leopard, and it's something I'll work on next. Lion simply brought some much-needed upgrades to table based UI development, which I wanted to use. It cut down the development time by a significant amount. Supporting Snow Leopard requires a rewrite for most of the UI logic. I wanted to get the first version out before crossing that bog.
- ra 15y agoThanks for explaining, that makes a lot of sense. BTW: If your firewall works on Snow Leopard and allows me to disable the P2P part of Spotify, I will buy it.
- leviathan 15y agoGreat app. One feature request though, it would be very useful to be able to view the complete URL of HTTP connections. God knows how many times I had to setup a local proxy to find out that information.
- daviddoran 15y agoI think this app works at a lower level though, by intercepting TCP connections. To show you the URL it would have to proxy all the traffic and understand the HTTP protocol.
- aparadja 15y agoThat's right. Of course, parsing the http requests isn't a monumental task, and it could be done. I'm just not sure whether it's worth it. Wireshark already exists, and I see no reason to compete with it.
- antirez 15y agoRelated: https://github.com/antirez/iconping https://github.com/antirez/iconping
- ahmetalpbalkan 15y agoI don't think it is related. It is just an app pings 4.2.2.2. Will not be useful when you have a stable internet connection.
- ahmetalpbalkan 15y agoSo are you going to show contents of the http (or whatever) requests and responses in a paid version, right?
- hmottestad 15y agoBandwidth. Bandwidth usage would be nice. This is something that little-snitch doesn't already do and you can't see it in activity monitor as far as I know. Any chance of right-clik "record traffic to file for X seconds"?
- aparadja 15y agoBandwitdh measurement isn't trivial, but it's something I'd very much love to add. Thanks for the input.
- heliostatic 15y agoBeyond bandwidth monitoring on a single machine, a simple snmp monitor would be amazing...
- kalleboo 15y agonettop in the command line does it (added in Lion), maybe you can scrape it out of there or find the source to it to see how it's done.
- brndnhy 15y agoFantastic. Thank you for that.
- dgallagher 15y agoApple does provide this in Activity Monitor. Click the "Network" tab and you'll see "Data received:" and "Data sent:". It tally's since the last reboot. It would be nice to have a history feature though. Plus, there's no easy way to ask "How much bandwidth do I have left this payment period before Comcast starts billing me for going over my monthly limit?" You'd have to tally total bandwidth, and then associate it with an internet connection. You could track internet connections via DNS/public-IP info, and possibly MAC address for WAPs. If you're a laptop user jumping from WAP-to-WAP, it would be nice to know when you're online at home, or in a Starbucks, and differentiate total bandwidth used for each.
- huskyr 15y agoGreat work! I really like the nice clean interface. It would be great if there would be an option to put it in the menu bar and hide it in the dock.
- albertzeyer 15y agoI wonder how it works, i.e. what APIs it is using, etc. Any details? Question on SO: http://stackoverflow.com/questions/7696890/macosx-how-to-capture-network-events-or-how-does-private-eye-works?utm_source=Stackoverflow&utm_medium=twitter http://stackoverflow.com/questions/7696890/macosx-how-to-cap...
- aparadja 15y agoAnswered directly on SO.
- fletcher 15y agoIt seems like you check for SYN packets, so there is no way to just see the connection currently active. This in my opinion limits the usefulness of the application, it would be cool to see an update that can have a tab for "live" connections and one for the "history". Thanks for the app anyway.
- evilswan 15y agoOk what's 'helpd' and why does it call Akamai servers? http://imgur.com/IDc5f http://imgur.com/IDc5f
- rhubarbquid 15y agoIt's probably checking for updated help files. Apple regularly uses Akamai's CDN.
- makira 15y agoWe do something similar in one of our app, although we also permit the user to block connections it doesn't want to. http://www.metakine.com/products/handsoff/ http://www.metakine.com/products/handsoff/
- runjake 15y agoThe bandwidth suggestions are good, but rather than suggest more, I'll just say I really like the way you've laid things out. The UI lets me see data via the angles I'd want to see it.
- aparadja 15y agoThanks! I spent a decent chunk of notebook pages and pen ink to get it the way it currently is. It feels really good to hear someone appreciates the design.
- andrewcooke 15y agothis looks useful, so i had a look for the linux equivalent. turns out there's a command line utility called nethogs that does something similar (it shows bandwidth per process, but not addresses). for opensuse you can get it here - http://software.opensuse.org/search?q=nethogs&baseproject=openSUSE%3A11.4&lang=en&exclude_debug=true http://software.opensuse.org/search?q=nethogs&baseprojec... another command, iftop, shows connections, but not processes (that's in the standard opensuse repos).
- skada 15y agoIs there something like this for Windows ? (Especially with ip resolution feature )
