 Thanks for your prompt reply.

 Just out of curiosity what's this 'MTU' stands for?


MTU stands for Mark T Uemura, otherwise known as mtu@, an OpenBSD 
developer who has been kind enough to do some fantastic write-ups and 
interviews on the events and people of the two most recent hackathons.

http://undeadly.org/cgi?action=searchmode=thres=method=andsort=timequery=mtu

Now, all kidding aside, please look at the length of your question above 
and compare it to the following URL:

http://www.google.com/search?as_q=MTU

Yep, the URL is shorter. Answering your own question would have been 
less typing, a whole lot faster, and far more complete than the simple 
expansion of an abbreviation given to you in replies.

The half dozen idiots posting replies with the correct answer to your 
easily answered question have done a disservice to both you and 
everyone else subscribed to this list. Mindlessly blurting out an 
easily found answer is tantamount to bragging and makes the people 
doing it look stupid since it shows they failed to think things 
through. They robbed you of a chance to learn something on your own, 
they cluttered the mail boxes of thousands of people, and worst of all, 
they encouraged all the countless other people like you to be lazy.

There's nothing wrong with not knowing things, but if you're unwilling 
to at least try learning and try solving your own problems *before* 
asking for help, then you obviously don't respect the time people 
commit to writing software and helping others on these lists.

The correct order of operation is Think, Search, Study, and Try. When 
you've repeated the first four steps a few times and you're still at a 
loss for an answer, only then take the fifth step of Asking. It's the 
tough road to take rather than the easy way out, but in the end, you'll 
be stronger and better for it.

In a similar vein, you might find the following thread enlightening:
http://marc.info/?t=12143420236r=1w=2
Particularly:
http://marc.info/?l=openbsd-miscm=121434335503622w=2

Yep, this crap happens all the time. It's not just new people showing up 
on the lists and not knowing the basics, but it's also long time users 
like Paul and Josh forgetting the end result of being overly helpful. 
Heck, if you search the list archives, you'll probably find places 
where *I* have made the exact same mistakes.

I may seem like a complete ass for pointing the obvious, but none the 
less, all of the above are things you, and others, really need to learn 
and remember.

this kind of replies do have a long tradition in this list - probably most
of the times for a good reason! On the other hand, calling people idiots,
isn't really polite, to put it mildly, neither serves any good cause!

I fully agree with your definition of the correct order of operation and it
wasn't my intension to abuse any resources. I don't know if you read the
whole thread but my initial question was a bit different! I didn't just
jumped-in with the question 'what's MTU'. It was a result of a kind reply to
my problem and after looking the man pages, where this acronym wasn't
defined, assumed that a generic term like this will, most probably, produce
a lot of unrelated and misleading hits in Google. Proved wrong! Still this
wasn't an outcome of being lazy doing my homework. As a result, I think you
heavily exaggerate with your strong wording.

Thanks

George

If you watch the fungames from mis-matched MTUs, methinks
you will discover that it is NO exaggeration.

tcpdump -X

Dear list,

was going through the OpenBSD tcpdump version and couldn't identify anything
like the '-A' flag in order to capture full web sites etc. Tried optin '-X'
but didn't work! Should I use '-s snaplen' but what snaplen value do I have
to define. Tried few combinations with no success!

Thanks for your help
