Networking :: Scp Interfering With Video Streaming Traffic?
Mar 24, 2010
I am streaming a MPEG-2 transport stream file over RTP from system A to system B . System B is continously copying huge number of small size files using scp to system A . The problem is while copying files from B to A I expecience packet loss on the received streamed video
The two systems are connected via a LAN switch.My question is : Is it happening because scp traffic interfering with streaming video . Or there can be any other reason behind this.

I successfully installed darwin streaming server .. I stream Audio through internet well but videos I can stream locally in my network only .. when I am connected to internet outside my network .. it doesn't stream I think their must be ports opened for that .. or any 1 have any ideas .. the audio is streamed on port 8000 .. video is streamed on port 7070 but locally only .. I opened those 2 ports in my router only the audio is working .. also I opened ports 554,7170 disabled the firewall of the router .. is it a problem of ports or something else .

I need to set up my centOS computer as a firewall in my home network. Ive got 2 interfaces, eth0 and eth1. I want to allow and forward all traffic on eth0 and block all traffic on eth1 except ssh, ping(icmp) and DNS. How do I do this? Ive tried some editing in /etc/sysconfig/iptables but no luck.

I wanted to tell my server to block all traffic but US only traffic. So i followed this guide:[URL].. Now I know, it's the best way to help prevent hackers/crackers (doesn't matter to me what they are called. I just have to stop them). My server only deals with US clients anyways so might as well just start right there for my server's security before getting into the brute force and injection preventions. So I got it all done compiled everything moved to the proper directory. I then started to setup my iptables. Like so
Code: iptables -F INPUT
iptables -F OUTPUT
iptables -I INPUT 1 -s *.*.*.* -p tcp --dport 22 -j ACCEPT
iptables -I INPUT 2 -s *.*.*.* -p tcp -j ACCEPT
[Code]...
After seeing that i went digging in the code and figured it was something todo with memory allocation.

Recently I notice that when I'm connected to an vpn server (pptpd) and I'm using it as a default gateway my download and upload speed decreases almost to the half of the usual speed. I made a test using iptables in order to count how much GRE packets are generated (except the real traffic itself) in that way:
Code:
iptables -I INPUT -p gre -j ACCEPT
iptables -I OUTPUT -p gre -j ACCEPT
iptables -I FORWARD -s 172.16.10.101 -j ACCEPT
iptables -I FORWARD -d 172.16.10.101 -j ACCEPT
The first 2 rules match all GRE packets between the pptpd server and client, and the next rules - the traffic between the server and the client.
When I turn the counters to zero and begin to generate traffic (to browse, to download etc.) I see that the GRE packets are even more than these in the FORWARD chain.
So, my question is first of all is my test correct and is it true that so much gre traffic is being generated during the browsing (it becames clear that the traffic is double than if the pptpd wasn't used as a gateway) and if yes - can that traffic be reduced?

I am trying to get streaming video to work on install of fully up to date Ubuntu 9.10.
For example: [URL]
I am guessing that the packages/codecs necessary cannot be distributed with Linux due to license issues.

I have a ubuntu desktop running 9.04 and a Acer Netbook running UNR 9.04.
Using NFS I have shared my videos from the desktop and have it automounted at start up on the netbook. I can navigate to the files but once I click play, the netbook locks up.
Is this a limitation on my hardware or is there a better way to "stream" these vids?

Is that requires a video streaming in case of only capture images and store it, without transmit it over the internet?

It is possible (I'm sure it is but I don't know how), to stream video program played on one Linux computer equipped with DVD so it can be watched on another Linux machine? I have pretty fast Internet connection. I watch UNIX Academy training DVDs on a laptop, however I would rather stream it and watch on my netbook which is much lighter and more portable. Where should I start looking for a solution?

I am using opensuse 11.2 Gnome. Screensaver is spoiling video streaming and I have to manually stop it every time. There are options in media players to stop screensaver but when I watch videos online it seems like there is no global option to stop it. Is there a way to resolve this issue?

I don't know why, but I can't seem to just play video files (stream them) directly through the internet using MPC or any other media player. It is a bit weird, because I think I was able to just a month ago. I have made some changes to the general setup of the apache server, but nothing major, and I have no chance of reversing it all.
Instead, when I try opening the url using "Open file" it doesn't just open it an begin playing from the internet, but instead appears to be frozen. However, If I let it be "frozen" long enough, it will eventually play the file, indicating that it has downloaded the entire file to a temp location on the hard drive.
Is it something with the permissions? Actually, I went and made everything in /var/www/ 777, as it is not known by a domain name or registered anywhere. I am just connecting though my IP address as the server is located locally. Even this didn't help.

I would like to stream my HD Movie collection over a wireless network to my PS3 and/or Xbox 360.
All my movie files are MP4s and I wondering if it is possible to do this. If possible, I'd like to use the VLC player to do this but its not too important. I really really really do not want to sacrifice any video or sound quality while streaming.

My local priest has asked me if I can use my computer skills to stream church services live for people who can't make it to church.I said, sure thing! I thought it would be simple, but the deeper I look into it, the more lost I have become!Here's the tech requirements:
- A camera with good optical zoom and focused on the altar (the camera will be stationed at an unobtrusive point at the back of the church on the choir balcony)
- Everything must be wireless (power is available on choir balcony to power the camera).
- Sound should be synchronised perfectly with the video (have access to the church PA system - located behind altar)
- the internet connection should be able to upload the stream to a virtual server (i.e. with root access) that's accessible to the web with ease. What upload speed would I need? Would 256k be enough? HD video is not required - ..... quality would be great. We can upgrade to HD at a later point in time!
- What bandwidth requirement would my server need if say 1000 users were connected? Seeing as they would most likely be locals, would just one stream be sent to the local exchange and that exchange would send out the stream to the 1,000 users, or would each user have to have a dedicated connection to the server?
- Say I bought a camcorder with HDMI output, what kind of processing power would I need to convert this to compressed video? (I've got an old Pentium 4 and an AMD64 2.0GHz lying idle in my bedroom and it would be great to make use of 'em instead of chucking 'em on the skip)
- I'd like all this to be done so that HTML5 browsers can access the video, resorting to flash if necessary
- I'd also like to be able to power down all the hardware with ease: i.e. set a timer. I'm sure ubuntu can do this with ease? What about configuring the camera to zoom in every time it is powered on? Can linux control the zoom on a camcorder?
- Am I totally nuts?

I've got a NAS mounted on a linux machine, and here at another location, I have my Ubuntu laptop. I'm able to remotely, securely mount the directory my NAS is mounted on in the linux machine onto my laptop via sshfs, giving me remote access to my NAS via my laptop.The problem I'm having is.. even though I have a high downstream at the laptop end, and a hefty 1mb upstream at my home, I still can't quite stream the movies I have stored on it. I can stream them, but there is a lot of stuttering.I've tried messing around w/ various options w/ mplayer, but I can only improve it slightly at best. Am I missing something? Is it a size issue that it comes down to? The files are roughly 700mb for a 1 1/2 - 2 hr avi file.

When I play streaming video on hulu or other sites it is choppy. However, the sound is fine. Video files play fine when I download them.I experience this problem in both Firefox and Chrome. I have a 10MB connection on other Linux desktops the streaming video is fine.I imagine it is a flash issue, but I have the latest flash v10.1.The other solution would be a video downloader for streaming video. I have not found one that works on Linux.

I am elevating this thread up a level from [url] . Ubuntu 9.10 no longer streams without the screen pausing and going black every 2 minutes! Our product was just going into production and now we need to hopefully find a version of Ubuntu that streams video! We couldn't go with Unbuntu 10.04 because the video streaming was 30% slower than 9.10.

I'm not sure this is, strictly speaking, an Ubuntu problem (although it may be), but people around here seem to be more knowledgeable than they are anywhere else, so it's worth a try.
CNN recently started offering its news station on live streaming video for those who get CNN from a participating cable provider. For better or worse, I get CNN on Comcast, so no problem there.
Except for lagging video because lack of processing speed, it all works fine on my netbook, on which I have Ubuntu 10.04 installed.
But on my desktop, where I'm using Ubuntu 11.04, no such luck. The problem is the same regardless of whether I'm using Opera, Firefox or Chrome.
I can go to http://cnn.com/video and get the standard video streams (not CNN live) just fine. When I click on the "Live" button and then the "Unlock Live TV" button, I get, as expected, the "Sign in to watch live TV" dialogue box. So I click on Comcast, log in correctly, and am returned to the main screen. The page appears to be loading correctly, and then I get the "Sign in to watch live TV" dialogue box again. No matter how many times I try, that's what I keep on getting.
If this didn't work on my netbook, I'd just assume that for some reason the setup is Linux-unfriendly, but now I'm determined to get this working.
I've checked my plugin settings on my browsers and nothing seems amiss. I've tried deleting all cookies, persistent storage, Flash cookies and all such things, but to no avail. Even though I had the most recent version, I even uninstalled and reinstalled Flash, but that didn't change anything.
