if there is a simple wifi scanner for Linux. I need only basic information such as access points in the neighbourhood, signal strength and their broadcasting channels. I want to know the broadcasting channels in order to set my modem in such a way to avoid interference.

I tried ubuntu and am very happy with the smooth running and clean interface. I am having trouble setting up my network connections. It seems that I am unable to connect to the internet via my broadband modem if I am connected to my LAN via wifi. I think I need to seperate the networks so that the internet traffic does look on the lan for [URL]. I don't think I have had this problem when I used much smaller distros where I had to set it up by hand.
I might need to add some details I am just not sure what is relevant. I only have a basic understanding of what is going on.
solution:
Solved in #ubuntu irc chan with help by erUSUL.
Just in case anyone else is searching for the same thing.
In network connections in the ipv4 settings tab I edited routes by clicking the button and checked the box next to: "use this connection only for resources on its network"
I am running 64-bit 9.10 on a Acer Aspire 1810T. I can connect to the internet via both wifi and the Novatel U998 modem. I have a PPTP VPN that works correctly via wifi, but does not work via the modem. The obvious problem would be that the ISP is doing something... but I'm dual booting Windows 7, and the ISP's Windows based software is able to connect to the VPN without issue.
I'm running VMWare player to be able to access my required Windows apps, so I'm almost in a position to dump MS if I can get this VPN issue resolved.

I've installed RPMforge and Smart Package Manager.
I had to create my own Centos 5.5 channels to sync yum repos and smart channels.
Here's the Centos 5.5 channel file for Smart:
Just shut Smart PM down, copy this file into /etc/smart/channels, and restart smart.
Smart should then detect the new channels (repos) for Centos 5.5
Update your channels in Smart, and you should then have yum repos and smart channels both in sync, looking at the same set of packages.
Copy this to CentOS-Base.channel, and add it to the /etc/smart/channels directory.

Friends i have an idea to broadcast few local TV channels to the world via internet.But friends i can't directly broadcast from my country because of bandwidth.friends is there a way to do this through a remote server server? i just need to input my stream to a remote server and then broadcast it from the server.I can stream channels to the server from my country through a 10mbbs connection.
View 2 Replies View RelatedI've got a recurring problem on the latest install of Ubuntu 10.4 64 Bit. Everytime I log in, in order to use establish a wifi connection I have to enter my password again to unlock the system keychain. Until I do this no Wifi connection is established.
I've got the system setup on an Acer Aspire Revo which has an RaLink rt3090 card in it. I was using the 2.1.3 driver but have updated to the latest .7 driver and still have them same problem but I suspect this is some sort issue with Ubuntu rather than the driver.
The machine is setup as an HTPC to logs in automatically and boots up Boxee which needs an internet connection so it'd be great to get the internet working from the get go rather than having to enter the password again.
Anyone got any ideas why I'm being asked to unlock the key chain again and to stop this from happening so the wifi works immediately after logged in.
I was asking around in some IRC channels earlier trying to develop some thoughts on how NFS is better than CIFS. I set up a FreeNAS file server, and that's where all of my data now resides on a pair of raided drives. That way my main desktop, which is kind of a power hog gaming rig, can be powered off since I pretty much live on my laptop now. Anyway, I began to tinker with CIFS and NFS. Since some family members in the household use Windows, I definitely need CIFS. But I wanted to bounce back to NFS too and check it out.
While I do think it's nice I don't have to worry about authentication to the NAS box when using NFS, it's still a little scary. Being that it's more of a trust method instead of actual authentication, truthfully all a user needs to get into your data is the path to your NFS share and a matching UID. I mean, am I wrong by saying this? Sure, it may seem like NFS is convenient, but this angle of it is a little scary. I just don't feel like that screams "secure."
On the flip side, you have CIFS, which uses a user authentication level. So I hit my little shortcut to my NAS and it asks me who I am. I log in and bam, I have connection. I can browse other folders on the share, etc. This is convenient because I do have a "public" share on here with a generic user. That way if friends come over and want to transfer something to me, I have them drop it in the public share and I later transfer it accordingly. Since there is a user level authentication, this to me seems a little more secure.
Speed wise I was a little concerned, as some users have said NFS is faster than CIFS. Well, they might be right. But I did a few bench tests here on my laptop, using the same exact share except one with CIFS one with NFS. I stayed in the exact same location and transferred the same 300mb file in each instance.
NFS - 1.7mb/s
CIFS - 1.5/mb/s
Not exactly enough to warrant a huge argument over, so I leave that argument along the road to be forgot about since it doesn't really have any bearing on this situation. I like things about both NFS and CIFS. I just want to know why is it "not optimal" to use a full blown CIFS setup even if you're using 100% Linux systems.
find and install modem driver for the Alcatel X200 USB modem?
I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.

all I get is the broadcast address can be used to send packets of information to all computers on a network simultaneously. Can that be used during MPI programming or anything of the such? What is the day to day use of the broadcast address?

View 7 Replies View RelatedI have a Dell Vostro 1400 with a BCM4311 Broadcom wireless card that I just reinstalled with 11.04 from 10.04. I have the drives installed and it seams to be working when i run the 'Additional Drives', but I can't get the wireless adapter broadcasting. I followed the instructions given in the knowledge base on installing Broadcom Wireless, to see if I could get it running and that is where I saw the difference between the example and my computer when writing the 'sudo lshw -C network' command. In the example it said it was broadcasting under configuration (just like my wired networks below) and in mine it does not (see below for copy past).
I can't find a tickbox in the systemtray to enable the wirless networking that I had before the update to 11.04 (the 'Enable Networking' tickbox is still there and the wired network works fine - that is how I got online to do this post). I have the hardware switch turned on and I have been in the BIOS and made sure that the Wireless is enabled.Anyone who knows what could be wrong? Where could I go from here?Quote:

I'm looking for a solution to broadcast messages on the network. All systems are Linux / Ubuntu.
It would be used in case the server has to be rebooted. It saves me a walk to every office in the building.
This is not a linux specific question more of a general network issue with the hope that someone may have already done this under linux.My problem:I have a red hat linux machine transmitting IP multicast packets onto an ethernet gigabit network (cisco switch).Wireshark (running on a different red hat linux box confirms packets on network.

When someone creates a network loop (a cat 5 cable is plugged into two ports on a switch), the 2 subnet get flooded and become very slow.
How can I prevent subnet 1 from getting flood if someone create a loop on subnet 2.
- eth2 go offline automatically until the network loop is canceled.

I'm using F15 with two nics, each on different subnets 192.168.1.0/25 and 192.168.1.128/25. My issue is that on boot my 192.168.1.2/25 interface sets a broadcast address of 192.168.1.255 which is incorrect I believe. Its broadcast should be 192.168.1.127. I've tried setting the broadcast param in ifcfg-p3p1 file "BROADCAST=192.168.1.127" with no benefit.I can change this after boot of course, but that removes my default gateway for some reason.
View 2 Replies View RelatedSo I just changed my network card settings recently, and I'm now getting no response when I ping the broadcast address for them... the cards are all connected through a switch with IP addresses 192.168.0.x, broadcast 192.168.0.255... ifconfig on all of them shows UP BROADCAST RUNNING MULTICAST, but nobody responds to a broadcast packet. Any thoughts?
EDIT: Pinging each machine individually works fine.
When setting up an alias for eth0, the interface works as expected for normal traffic, but does not receive broadcast traffic.
Host 1's setup:
Code:
Pinging host 1's normal interface from host 2 works as expected:
Code:
Pinging host 1's alias interface from host 2 works as expected:
Code:
Broadcast pinging from host 2 only gets a reply from host 1's real interface (as well as some other uninteresting devices on the network):
Code:
I have confirmed by listening on both interfaces using netcat, and broadcasting using netcat, and again only the real interface receives data.
Is this by design, or is it possible to get interface aliases to receive broadcast traffic?
I dont know the difference between these topics.
