Need help understanding output of pathping

Paul Randall

Hi
Hopefully this is the correct microsoft.public newsgroup for questions about
command line utilities. Please give me a better newsgroup if there is one.

I'm trying to understand the output of pathping. Here, and attached as a
text file, is the output I get:

C:\Documents and Settings\Paul>pathping www.microsoft.com

In the statistics section, there seems to be one line generated for each
numbered hop. The header area indicates that the line contains two
percentages: "Source to Here Lost/Sent = Pct" and "This Node/Link Lost/Sent
= Pct". Between each of the numbered hop line is another set of info of the
form "Lost/Sent = Pct" but there is no explicit header info to tell me to
what this applies, although perhaps "This Node/Link Lost/Sent = Pct" means
that on the numbered hop line is "This Node Lost/Sent = Pct" and the
following line is "Link To Next Node Lost/Sent = Pct".

If I just look at the section from hop 2 to hop 4:
2 19ms 0/ 100 = 0% 0/ 100 = 0% 174-126-32-1.cpe.cableone.net
[174.126.32.1]

0/ 100 = 0% |
4 18ms 0/ 100 = 0% 0/ 100 = 0% boi-edge-02.inet.qwest.net
[67.134.58.73]

I can understand that the IP of hop 3 is private, probably that of a router
internal to cableone.net, and so all timing packets to and from it should be
lost. But this gives me no clues as to why the lines between hops 2 & 3 and
between hops 3 & 5 both have "0/ 100 = 0% |".

Then I look at hops 9 to 11:
9 39ms 0/ 100 = 0% 0/ 100 = 0% 209.240.198.66
100/ 100 =100% |
10 --- 100/ 100 =100% 0/ 100 = 0%
ge-0-2-0-0.tuk-64cb-1b.ntwk.msn.net [207.46.47.70]

[207.46.46.17]

and I'm still confused.

I'm hoping someone explains, or posts a link to an explanation of exactly
what "Source to Here" and "This Node/Link" mean, and maybe what goes on
within the "Computing statistics for 325 seconds..." process, packet-wise.

Thanks

I was going to say this ng was more about batch scripting, as your question
seemed a little out of place. Looking over a few other posts, however, I
guess it is not off topic.

I don't know the answer to your question, but googled one reference that
might help:

https://help.maximumasp.com/KB/a445/connectivity-testing-with-ping-telnet-tracert-and-pathping-.aspx

It also occurs to me that the terms are not defined in the "/?" help because
it is probably assumed that someone using a networking-oriented command-line
utility would not need the terminology explained. Have you considered
looking for a networking newsgroup?

Thanks for the link, Al

I tried to make sense of it, but it also confuses me. It looks to me like
it is using made-up data and the author got to the point of saying something
important:
"A 0/100 = 0% means that out of 100 packets, none were lost. A low single
digit loss 1% or 2% is common, but anything higher is an indication of"
and then realized that there are three sets of statistics for every hop and
he had only talked about two of them and then realized that maybe he was
talking about the wrong one at this moment, and then got sidetracked and
never finished that section of the writeup. The program's built-in usage
info and all other sources I've found also only talk about two of the three
statistics and are unclear about which of the three that appear in the
statistics section they are talking about at any time.

My condolences. It confuses me too, even though I didn't try to make sense
of it.

You seem to be trying to make sense of the parts of the output that you
currently do not understand. Is this just for curiosity, or do you have a
particular need for information that the pathping command might be able to
provide? If the latter, what is it that you actually need? Perhaps there are
other ways of getting it.

Trace complete.

In the statistics section, there seems to be one line generated for each
numbered hop. The header area indicates that the line contains two
percentages: "Source to Here Lost/Sent = Pct" and "This Node/Link
Lost/Sent = Pct". Between each of the numbered hop line is another set
of info of the form "Lost/Sent = Pct" but there is no explicit header
info to tell me to what this applies, although perhaps "This Node/Link
Lost/Sent = Pct" means that on the numbered hop line is "This Node
Lost/Sent = Pct" and the following line is "Link To Next Node Lost/Sent
= Pct".

If I just look at the section from hop 2 to hop 4:
2 19ms 0/ 100 = 0% 0/ 100 = 0%
174-126-32-1.cpe.cableone.net [174.126.32.1]

3 --- 100/ 100 =100% 100/ 100 =100% 192.168.49.49
0/ 100 = 0% |
4 18ms 0/ 100 = 0% 0/ 100 = 0% boi-edge-02.inet.qwest.net
[67.134.58.73]

I can understand that the IP of hop 3 is private, probably that of a
router internal to cableone.net, and so all timing packets to and from
it should be lost. But this gives me no clues as to why the lines
between hops 2 & 3 and between hops 3 & 5 both have "0/ 100 = 0% |".

Then I look at hops 9 to 11:
9 39ms 0/ 100 = 0% 0/ 100 = 0% 209.240.198.66
100/ 100 =100% |
10 --- 100/ 100 =100% 0/ 100 = 0%

ten1-2.tuk-76c-1a.ntwk.msn.net [207.46.46.17]

and I'm still confused.

I'm hoping someone explains, or posts a link to an explanation of
exactly what "Source to Here" and "This Node/Link" mean, and maybe what
goes on within the "Computing statistics for 325 seconds..." process,
packet-wise.

Thanks

For the moment, just curiosity. I like to understand something before I
recommend it to others. I think PathPing would often be useful but about
all I could say to someone with a question about it is "Your guess is as
good as mine". I was hoping someone here had come across a definitive
description of it.

Thanks for the link, Al

I tried to make sense of it, but it also confuses me.
My condolences. It confuses me too, even though I didn't try to make sense
of it.

You seem to be trying to make sense of the parts of the output that you
currently do not understand. Is this just for curiosity, or do you have a
particular need for information that the pathping command might be able to
provide? If the latter, what is it that you actually need? Perhaps there
are other ways of getting it.

It looks to me like it is using made-up data and the author got to the
point of saying something important:
"A 0/100 = 0% means that out of 100 packets, none were lost. A low single
digit loss 1% or 2% is common, but anything higher is an indication of"
and then realized that there are three sets of statistics for every hop
and he had only talked about two of them and then realized that maybe he
was talking about the wrong one at this moment, and then got sidetracked
and never finished that section of the writeup. The program's built-in
usage info and all other sources I've found also only talk about two of
the three statistics and are unclear about which of the three that appear
in the statistics section they are talking about at any time.

Hi
Hopefully this is the correct microsoft.public newsgroup for questions
about command line utilities. Please give me a better newsgroup if
there is one.

I was going to say this ng was more about batch scripting, as your
question seemed a little out of place. Looking over a few other posts,
however, I guess it is not off topic.

I don't know the answer to your question, but googled one reference that
might help:


https://help.maximumasp.com/KB/a445/connectivity-testing-with-ping-telnet-tracert-and-pathping-.aspx

It also occurs to me that the terms are not defined in the "/?" help
because it is probably assumed that someone using a networking-oriented
command-line utility would not need the terminology explained. Have you
considered looking for a networking newsgroup?
