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 George

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=search&mode=&thres=&method=and&sort=tim... 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=121434202300006&r=1&w=2 Particularly: http://marc.info/?l=openbsd-misc&m=121434335503622&w=2 Yep, this crap happens all the time. ...
On Thu, Jul 17, 2008 at 9:04 AM, J.C. Roberts <list-jcr@designtools.org> 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 "fun&games" from mis-matched MTUs, methinks you will discover that it is NO exaggeration.
