Some programming problems

frostmagic · 10-03-2003, 08:56 AM

Could some one help? i am currently doing a video streaming platform. I have encounter some problems in it. I break down the file into small packets and send it over to the client from the server. It always hang at some stage of the time and i use Ethereal to check the problem. The ethereal last statement was
"Who has 10.0.0.2(client address), tell it to 10.0.0.1(server)". During this process, certain amount of data will be lost. Thus my client will not have to complete set of information. So could someone please find me?

Could you state some information for me, like are you using TCP or UDP? What platform/distro you are using? Are the server and client on the same LAN( im assuming they are since you used ethereal), etc.

Id be happy to help, i just need more details.

Thanks , i using UDP . I connect 2 computer just with a cross cable. They are under the same LAN. I dont know what you mean by platform, i am a new user to Linux system so some terms i dont really know. It just 2 computer connected to each other and do sending and receiving.

tcp will guarantee all data arrives in the correct order, with udp you have to handle the data-loss yourself

hmmm , there is no other traffic in the network , why will it be lost?

Do not use TCP for video frostmagic, you're smart with using UDP. It seems to me that if you are connected directly through
a crossover cable, it must be a bug within your software.

If you wish, you could email me a zip file of your code and I could take a look at it.

frostmagic · 10-05-2003, 09:36 AM

i gladly wish you could look for me, because i need to solve this bug within like 1 week. But my programming skills are very lousy, do a lot things through the long way. If you dont mind. Can i have your email address?

i agree, i was just saying perhaps his problem was because he didnt realise that udp packets arrive in a random order with some possibly missing and that you have to handle this yourself.

I figured that was what ya meant, you're really knowledgable, what kind of schooling do you have?

well thankyou

but there are a lot of people here who know more than me - david_ross for example.

as far as schooling goes ive never done anything related to computers, im totally self taught. at the moment im just starting my 3rd of 4th year of my masters degree in maths at durham university, england.

jinksys how was the code i send you , is there anything wrong with it?

jinksys · 10-06-2003, 03:31 PM

Honestly frosty, Ive been really busy with school so I havent been able to actually set up a network and test it. All Ive done so far is look over the code and see how its internals work. I have a question for you though, what is the other included file for? Is it the file you are streaming?

Tonight and tomarrow I am free, so i'll set up a dedicated network for it, and test it.

Hmm , sorry for troubling, hmm , ya it is the streaming file. Now i am only streaming a text file. Once i find the problem in the program , i will be streaming a mpeg file.
