How do I get the VideoLAN device information that corresponds with /dev/video, and /dev/video1 for vlc targetting?
This command kind of does what I want code...
However I want to target my second webcam, not the first one. How do I do the v4l2:// for my second webcam?
I have a dual CPU system, where each CPU has 4G of associated RAM. I would like to know how to determine the logical memory address start of memory in the user address space for each CPU. I am running OpenMP, and have 16 threads, for a problem that parallelizes. What I would like to do is to be able to put half the data on each of the 4G, so that each processor will have half the data local, and thus reduce the amount of data transferred from one CPU to the other.
View 3 Replies View RelatedI have a fairly standard home network set-up with a router and a couple machines on the internal network (with private IP addresses 10.0.0.x). One of these machines is running my subversion server, which is in turn used by my laptop. I am now trying to configure my laptop in a way that I can have one working subversion copy connected to the repository which works both when the laptop is connected to my home network as well as if its connecting from internet. I configured a "virtual server" on the router, so that port 443 goes to the machine with subversion, and this works fine. Now I don't know how to configure the laptop to go to the same machine - because the IP is different if I want to access it from outside and from inside. I tried to connect to the external IP of my network, but the router refuses to let the connection go "out and in again". how to get it configured?
I am using Debian linux with wpa_supplicant on the laptop.
i understand autostarting an app is done at setting > session and startup > application autostart.
where is the vlc app located?
i've tried
usr/share/vlc.ico
&
usr/share/vlc.desktop
none of those two have worked.

View 1 Replies View RelatedIt's more just straight networking rather than Linux related - possibly a rather large gap in my knowledge.Been asked to set up a Linux firewall / router for a friend, and he wants an external address on his PC and his firewall. He's got a /30... ISP seem to think this is normal. My understanding was different router interfaces should be in different subnets when it comes to addressing. eg:
WAN 1.1.1.1LAN 192.168.1.1/24 (then PC 192.168.1.2)This is how I'd set up an enterprise router, and from memory how I had to regurgitate networking for my Cisco exams. But they would have been large devices within a BGP environment, how does this compare to home use? Can you have interfaces on the same router within in the same subnet? I'm looking for the real world answer - not my CCNA answer or the config addressing scheme I just blindly followed...Is this right or can different interfaces be in the same subnet?If they can be in different subnets How would you do that with an eternal 1.1.1.1/30? egWAN 1.1.1.1LAN (what IP?) then PC 1.1.1.2Would you actually just set the router up as a /29 and then use the additional IP addresses for the LAN NIC on the router? (yes I'm aware you couldn't route to where it had actually been allocated)
Then with that how do I route the 1.1.1.1/30? Which interface do I point it at? Even with a /29 I'd still have a routing issue right?Or are the ISP expecting you to do something with NAT / port forwarding. (and yes I could do this to get it working - but I want to understand it better) I'm asking the question here, because rather than just wanting a magic file to get things working, I'd actually rather understand the principles rather than just press a button and have it work.

I'm wanting to set up a network. I'm still confused as to how to set it up. I think the easiest design is to have a switch on my border router.n this switch will be the servers. Also attached to this switch will be a Linux box. This will be a dedicated firewall. On it will be another switch. And the machines on the internal network will be attached to this switch. In the book "building Internet firewalls"(o'reilly) this set up is described as a screened subnet architecture. However the external interface on the Linux dedicated firewall will have to get it's I.P via dhcp (192.168.1.*) from the border router.
That or it can be a static I.P on the same subnet as the border routers dhcp range 192.168.1.*(but outside the dhcp range) but that would be trickier.The internal interface of this dedicated firewall would be static and on a different subnet as the external interface (192.168.2.*). Then this internal interface could give out I.Ps to the internal network that are on 192.168.2.*. If it did N.A.T for packets from the internal network then N.A.T would be being done twice; once by the Linux dedicated firewall and once on the border router, before going off to the net.Or is it a better approach to NOT do N.A.T on the Linux firewall and have all I.Ps on the whole network assigned as static(outside of the border router's dhcp range, but all on the same subnet(192.168.1.*))?.
Basically is there any point in the Linux box doing dhcp and N.A.T for hosts on the internal network?. I guess the answer is no. But i just wanted to hear your opinions, if you have the time. The border router is a home router. nted to have a normal triple-homed dedicated firewall and put it in the border router's DMZ but it proved unpredictable and tricky. So i just wondered what the best I.P addressing scheme would be for my newer way.

View 5 Replies View RelatedI've got a problem occurring with my openSUSE 11.3 // GNOME Empathy Chat Client. When I try to connect to my Facebook account, my client tells me that I have a Network Error. Last time I used the client at home, it worked perfectly fine, but when I'm at work it doesn't.
Now, you guys may say that my work's network may have ports blocked, or the firewall is blocking its use in some way, but I find that hard to believe. My reasoning? I am able to connect to my Facebook account thru Empathy at work on my previous Ubuntu 10.04 system with no problems. I have also been connected to the same chat accounts this whole week on my openSUSE 11.3 // KDE 4.4 Kopete chat client.My Empathy connects to my Skype with no problem also. So, do any of you have any ideas that could possibly solve my issue? I love being connected to my Facebook chat at work because I don't see anyone nearly as often, and it's a great way for me to keep in touch with them.
I'm wanting to set up a network that has a simple screened subnet architecture. The boarder router will have a switch plugged into it. My servers will be plugged into this switch. Also plugged into this switch will be a dedicated firewall. This firewall will protect the internal network. The boarder router is not very flexible. You can have hosts that use dhcp but that get the same internal I.P address each time their interface is configured.Or you can configure static I.Ps on hosts that are outside the dhcp range of the router, but that have the same subnet address.
The most simple way to set up such a network would be for every interface to have a static internal address that is obtained via dhcp from the boarder router. Like i said the boarder router is doesn't give you much freedom. Meaning that it lets you have a static internal address but not a different network address for different interfaces. That is where the confusion is, for me. If all the interfaces that get theirI.P addresses from the boarder router are on the same network, then what about the systems on the internal network. They might as well get their I.Ps from the boarder router as well, to avoid NAT being done twice before their packets get sent out to the Internet?.I wanted a three interface firewall to separate the DMZ from the internal network, instead of using a screened subnet architecture, but the boarder router only allowed one interface to be in the DMZ, i think and it didn't seem to have a well designed way of controlling the DMZ ie setting a new default gateway etc.
Should i let NAT be done twice for packets from the internal network i.e have the dedicated firewall do dhcp and NAT for the internal network, but this firewall's external interface have a static internal I.P from the boarder router, and the internal I.P of the dedicated firewall have a static internal I.P from the router as well?. It looks like all the interfaces have to have the same network and subnet address, except the machines on the internal network(which can get their I.P from the dedicated firewall)
Why does a NIC need a permanent individual way to distinguish it? Why not give it the host name in a form that is not a permanent hardwired hardware? Seems that the last ethernet router before reaching your PC is really seeking your NIC. So why is not the expression "What is your NIC Address" instead of "What is your IP Address"?
