Why ping doesn't work?

Recommended Posts

Hi to all

This forum is good, there is some time I visit it and found many helping things.

I wanted to ask (I'm on Hughes net, resident in Albania/Europe), why ping doesn't work to ping outside, that is, testmy.net or google.com? I tried with and without firewall with no results. All times there is timeouts.

I guess there might be a setting somewhere, on the modem or Windows XP, that needs to be fixed. That's the problem, I don't know where to look for :).

Thanks and Happy New Year to all.

In general, is this normal? For the ISP to block ping? I mean, I have to know ping rates to know what is happening with the satellite. What are the chances for them to say OK, we blocked ping but if you need it we will fix it?

I'm asking if anybody had a similar experience, I don't expect to get an answer if this didn't happen to you ;).

its not normal for ISP's to block ping, its a good tool to have. i would give them a call and see whats up.

Excuse me for one last question. Before I check this with the ISP, is there any probability that I should check my configuration (computer or satellite setup) first? Maybe I'm blocking it from here (though, I formated many times my computer and installed the software accordingly and I never got ping with outside).

But, I am directly connected to the modem. The XP I'm mentioning is the server. From this computer I cannot ping.

The scenario is like this: LAN-MikroTik router-XP server-Modem-Satellite-Hughes.net.

Actually it is normal.  They block incoming pings.  But if your outgoing pings won't work then.. well.. THAT would be weird.  Basically when someone tries to ping you they'll get nothing but you should be able to ping out to say google or testmy.net.   .. For instance, when I try to use my tool at http://s2.testmy.net/tools/toolbox.php  (or https://testmy.net/ping-enterIPorHOSThere for instance https://testmy.net/ping-google.com you can also query the following https://testmy.net/trace-google.com, https://testmy.net/whois-google.com, https://testmy.net/arin-google.com and https://testmy.net/all-google.com / https://testmy.net/runall-google.com) using my own IP I get the following...



Ping Results:
PING 68.98.19.3 (68.98.19.3) 56(84) bytes of data.

--- 68.98.19.3 ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 4014ms
[/code] But when I go to my command prompt ([start]+[run]+"cmd") any type  ---  ping testmy.net    ---  I get the following...
[code]

>ping testmy.net

Pinging testmy.net [67.18.179.85] with 32 bytes of data:

Ping statistics for 67.18.179.85:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 31ms, Maximum = 37ms, Average = 34ms

Even though this is the same ping I get different results, the reason is because the first ping is coming from testmy.net and going to my home computer.... BLOCKED.  But the second one that is going from my computer and going to testmy.net  PERFECT.  And for most people on a home ISP these days it's normal.  It's a security measure.  They usually block traceroute too, you'll be able to run the trace but it will only show you the trace up to the first few hops, once it starts to get closer to your personal computer the trace stops reporting... instead of the tracert looking like this...

... again, another security measure and many cable and DSL providers are doing it.

That is totally true. I have had troubles. But never that I could not ping out.
