I have a file on a linux box with the extension .gz thats supposed to be a gzip file. when i use gzip -d filename
it gives me squares and triangles and you know garbarge. Its a 900 meg file. Is there someway to decode the file and where could I store a 900 meg file for free???? I am going to lose this linux account it is a school account. This file has some intruging information i will love to see so would you. direction anyone.
thanks in advance
Binary files look just as you describe......
Lots of places on the net offer free storage... sounds like a 'google search' kinda question:
not binary tried that tried alot still no success i couldnt find any one who would let you store a 900 megabyte file basically a 1 gig file for free even if you payed i didnt see any 1 gig openings or am i missing something. a url would be super. anyone want to see the file to try and open it i will send it. it doesnt bite.
your the greatest dude.
thanks
Have you tried using file?
First, make sure it's a good GZ file:
$ /usr/bin/file filename.gz
gzip compressed data, deflated, original filename, last modified: Tue Dec 11 05:03:02 2001, os: Unix
$ gzip -d filename.gz
$ /usr/bin/file filename
It should give you a fairly accurate hint of what the file it...
you know what, that really helped its a tcpdump capture file
little endian version 2.4 ethernet version not familiar with this can you help again. what now? this file is supposed to be the capturing of what was happening on a secure network kinda like a security camera. you probaly understand this so far you know what i mean.
you guys and gals are the greatest.
Well, it you don't know how to view it / play it back, it probably won't be of much use to you anyways then...
If you're still interested, try man tcpdump. It says in the manpage how to Replay the session from file. By default, though, all tcpdump will display are the packet headers - not the entire packet.
Note: If you created / collected this file without the permission of the Systems / Network administrators, they could get more than a little mad at you for it...
OK. You have a binary file of TCPDUMP info on a shared system which means you have a file with captured passwords and logins (and maybe credit card info) on a shared system you do not own.
You don't understand what you are doing, so you obviously are not a system admin. I suggest you delete the file to protect the security of those users immediately and report the capture file to the owners of the system.
Or, report it to the system admins and give them the file.....
What legitmate use of a large file of captured network traffic data could you have on a shared system? Inquiring minds want to know 
Come on guys give me alittle respect. First of all this file was taped for people to look at. It's not any thing secretive or anything with passwords. To be honest its a file of information on networking security. It shows some of the best network guru's in the world exploiting a supposed to be secured network to show what not to do with your network. Supposedly. so that will eliminate all of the security talk. This file was for people to look at. Just for the record I might now alittle more than I lead on. I also am smart enough to know that you can learn from anyone. Hackers crackers occasional users or open forms like this one. Its always good to have a fresh perspective on a subject that may be difficult or elementary. Really I think something is wrong with the file must be corrupted because i have tried alot of these things still coming in as garbarge.
anyways if I run across it or fix it will let you guys know. You guys thought i was doing something wrong come on guys. Were all good people here. Users Programmers Sys Admin's or whatever you are. But thanks man you guys are smart i will contiune to think of any question that will spark your brain
Sounds like someone downloaded "Capture the Capture the Flag", from the last DefCon. The only way (to the best of my knowledge), is to read the file into tcpdump (or another packet-dump application that can read tcpdump files - there are a few out there).
Please see the post I made above.
Also though, you'll have a hard time getting anything useful from a raw tcp-dump if you can't even figure out how to open it...
(Note: the command is "tcpdump". If you don't have it installed, see if you can install it, or get the admin to install it)
