Check your router for open ports

35 points by bsdguides 14y ago

This site allows you to check your router for open ports and common vulnerabilities such as the upnpbug. Neat.

Is Steve Gibson's "Shields Up" still valid? It's what I always use. https://www.grc.com/x/ne.dll?bh0bkyd2 https://www.grc.com/x/ne.dll?bh0bkyd2

  Does he still write all of his applications in assembly? I always loved how enthusiastic he was about his products and SpinRite was a very helpful tool back before everything I had went to SSD.

I've been using GRC Shields Up all along; would like to try this one too. But, I keep getting this: Sorry, but the monkey that does the scanning is kind of busy at the moment. Try again later!

Hi Guys, yeah sorry it seems the server is kind of busy now. Cool...ill raise some limits.
- mikestew 14y ago
  The server is definitely overloaded, and at a time when most of the U. S. is either in bed or thinking about heading home from the bar (except me, obviously). Granted, the rest of the awakened world can put the hurt on your server, but I'd prepare for when the East Coast wakes up. :-)

Oh and yes, id like to built something similar to ShieldsUp - let me know if anyone is interested to join and help coding

  Any advantages to using this other than ShieldsUp (which has been around longer than I've probably been alive)?
  - bsdguides 14y ago
    It looks cooler - and eventually shall have more features and better explanations. Isn't a bit of change always a good thing :-)
    - jdaley 14y ago
      Sure, but don't just steal the Shields Up content! Your description of port scans has been copy-pasted from Shields Up. Your disclaimer text is identical except that "Shields Up" is replaced by "CheckMyRouter"...
      - bsdguides 14y ago
        Hmm thanks for that feedback. The site is really just getting started so certainly there are some rough edges; will rewrite the disclaimer part and shorten it while i'm at it. PS: Updated the common portscan description. Also, feel free to get in touch and make it better / more useful.

  It's rather disappointing that this doesn't default to using nmap's -PN option, since they can be reasonably sure that the host actually is up (after all, it just requested the web page). Not all routers respond to ping.
  - bsdguides 14y ago
    Ok ill change this, as soon as the storm is over...check back tomorrow :-)
    - kbuck 14y ago
      I was talking about portscan.me, not checkmyrouter.org - unless you happen to run both.

This seems infinitely useful, but "the monkey that does the scanning is kind of busy at the moment. Try again later!"

sounds like they are confused about what routers are. unless they are using traceroute.

  How so ?

    If a website sees the HTTP connection terminating at some other IP address than the machine your browser is running on, it's some kind of middlebox (proxy, NAT box etc) and not a router. The central concept of the packet-switched internet is that network nodes forwarding the packets (called routers) are just dumb packet forwarders and invisible to the communicating parties. It's called end-to-end transparency and it's what has enabled new Internet apps to be deployed without requiring support from the network. Like the web, or voip, or bittorrent. http://tools.ietf.org/html/rfc1812#section-5.2.1.1 http://tools.ietf.org/html/rfc1812#section-5.2.1.1 specifies what routers do when forwarding IPv4 packets.
    - Dylan16807 14y ago
      Just because it does other things doesn't make it not a router. The primary purpose of a router is connecting different networks at layer 3, and a consumer-end box is certainly doing so.
      - fulafel 14y ago
        What a consumer NAT box typically does is not routing. Routing is IP forwarding without messing with the packets. See the link in my post. Here are various other kinds of middlebox devices that are also generally about connecting networks at layer 3 with various side effects vs routing (just like NAT): http://en.wikipedia.org/wiki/Middlebox#Types_of_Middleboxes http://en.wikipedia.org/wiki/Middlebox#Types_of_Middleboxes None of these devices are internet routers. It's just wrong terminology.

what a stupid protocol

I'm not sure the design of the website matches what it does. It'll probably scare or at least worry a few people into thinking open ports are scary and bad.

WOW this thing's awesome. Didn't know i had that many ports open :)
