traceroute question

[ShizlacTheGreat]

Hey, tracerouting (w/o tags) from a linux box, behind a router, behind a cable modem, the first hop (10.blah.blah.blah)would be the modem, right, since the router is the gateway?
Also, I did'nt figure this out from MAN or info, but is there an option to use ICMP packets like windows?
Thanks.

[brunson]

You need to provide more information. A stand alone cable or DSL modem would usually be in bridging mode and would not show up in a traceroute. A combination router/modem would show up.

I'm not aware that you can get linux traceroute to use ICMP.

Yep. You can.

10.28.48.1 That would be the modem right?

and man traceroute,
does type of service have a flag to use ICMP packets?

[brunson]

man traceroute :-)

Vic.

Man, you are just a wealth of one line, unhelpful responses today. There is nothing in my man page about using ICMP in traceroute.

There is in mine. And if you type "man traceroute" into Google, the very top answer also tells you exactly how to use ICMP.

But you go ahead with your impetuous outbursts. I'm sure you prefer them to finding out answers.

Vic.

[brunson]

Yeah, that would be a man page for Mac OS X which uses BSD tools, hence the line

TRACEROUTE(8)             BSD System Manager's Manual            TRACEROUTE(8)

Why don't you just tell us to read the documentation for Windows traceroute, it has about as much pertinence.

This is a fedora forum, I looked at the man page on my fedora system to help a person asking a question about fedora traceroute.

I'll reassert:

Now, do you have anything useful to add to this discussion?

Yes.

I'm completely aware that you can get Linux traceroute to use ICMP because I am running Linux and my version of traceroute can use ICMP.

A little Googling would have told you the same answer - and how to get it to do it.

But never let the thought of a little investigation put you off from a good ol' flame-fest.

Vic.

[brunson]

I am running Linux and my version of traceroute can use ICMP.

No it can't.

A little Googling would have told you the same answer - and how to get it to do it.

No it wouldn't, not in Fedora.

[brunson]

I don't believe you, I think you made a flippant statement and were wrong and now you don't want to back down and admit it.

A little Googling would have told you the same answer - and how to get it to do it.

If you think I didn't search for this before I posted my first response, you underestimate me. If you think I haven't search much more closely before calling you on this, you're an idiot. Post a link showing how to do it if you have one. I would *l;ove* to be proved wrong on this.

I'll be surprised if you actually respond to this with any solid evidence.

Oh, fer crying out loud.

I'm using Linux :-

[root@goliath ~]# uname -a
Linux goliath 2.6.9-34.0.1.EL #1 Wed May 24 22:44:24 CDT 2006 i686 athlon i386 GNU/Linux

My traceroute man page has an ICMP option :-

[root@goliath ~]# man traceroute | grep "ICMP ECHO"
       -I     Use ICMP ECHO instead of UDP datagrams.

Now go away and hump someone else's leg.

Reallly? I thought you capable of realising the amount of code that is common to both BSD *and* Gnu/Linux, yet you pull up the BSD title as some sort of major deduction, and make crass comments about the application on entirely different platforms. I think I *overestimated* you...

One of us is. I found the same man page as on my machine (except for the BSD title) at the top of the Google results page.

You're wrong. More to the point, you have descended into name-calling just because you're wrong.

Then you really are an idiot. I'll add you to my ignore list forthwith...

I'll point out again that this is a Fedora Forum.

Again, useless information in a terse, smug format..

[ShizlacTheGreat]

So...... I would have to port or rewrite code from another distro or bsd to emulate a windows tracert.
or something.
Am I gonna end up like you guys when I get real smart?



Devoting a while tonight to reading up on traceroute.
