Does anyone know of an application that continually scans for devices on a network and notifies you if a device connects/disconnects to/from the network? I just want a way of knowing when a computer is connected and when it's not.

I checked the Network Icon and every time I check it indicates "disconnected" then refreshes and indicates connected. The log makes references to redat, which my machine has nothing to do with?

I'm doing a few tests with fedora 15. I'm surprised because they changed the naming way on network devices. eth0 is now called em1.At every fedora I have found the configuration files in /etc/sysconfig/network-scripts, but today I can't find them.
View 1 Replies View RelatedI'm just having a bit of trouble with activating my wireless card (see title for details). rfkill - I installed it but nothing was soft / hard blocked (whatever they mean). I did the rfkill unblock command anyway but it didn't appear to change anything Tried doing it manually through system-config-network but this yielded no luck either. Basically all it does is continually ask for my WEP key, even though I've typed it in correctly a million times. why I don't have WPA2 because I do not have the ability to change it
View 1 Replies View RelatedI'm having trouble getting my wifi devices to work on my 128bit WEP network. I have a new Thinkpad T400, with an internal Intel PRO/Wireless 5100 AGN. I also have some cardbus cards: a Lucent ORiNOCO Gold, a Linksys Wireless-G, and a TRENDnet TEW-421PC. I have them set up as interfaces eth2, eth1, and eth3. (The TRENDnet isn't recognised as a network card at all, so no interface for it.) I have installed the latest firmware for the Linksys card.
The /etc/sysconfig/network-scripts/ifcfg-* files are virtually identical for all of them, differing only in the HWADDR and DEVICE lines. So here's the behaviour:
1. The Lucent card comes up just fine.
2. The internal 5100AGN and the Linksys cards won't come up, and watching with iwconfig shows that they're either associated with my AP OR they've got an encryption key set -- but not both.
3. When trying to bring up the 5100AGN, I get the following messages:
iwlagn: index 0 not used in uCode key table
iwlagn: index 3 not used in uCode key table
/var/log/messages shows DHCPDISCOVER requests being sent, but they're bound to fail since the association with the AP with WEP isn't being completed. And yes, the ifcfg-* files really *are* identical except for the DEVICE and HWADDR lines. The /etc/udev/rules.d/70-persistent-net.rules file correctly maps the interfaces to the MAC addresses. So why does my antique ORiNOCO card work and thew newer ones fail? How can I track down what's being done wrong/not being done?
I'm looking for some help on how to troubleshoot the network on Ubuntu 10.04 64 Desktop. It's on a Acer Aspire 721. There's a wireless card but the widget in the top right says there is no network device.

He's had several thoughts on how to get this done and I know very little about this kind of thing so I thought I'd ask some of you.
His first thought was to buy a multi port bridge, but he doesn't like any of the ones he's seen so far.The other thought was to connect all of the devices to a switch and then use a single bridge, but he isn't sure if this would work.

How can I determine in a script which devices eth0, eth1, wlan0 exist and which hardware devices they apply too? Sometimes a wireless card is wlan0, other times it is eth1 or even eth3!

View 1 Replies View RelatedI've got three network devices on a laptop:
1. Built-in ethernet LAN
2. Built-in ethernet WLAN
3. PCMCIA ethernet LAN
I installed Ubuntu Server on this computer without the last one inserted.I inserted the last one today, and it lights up when i put in the cable. To be sure if Ubuntu has found it, I tested with the install CD and could see that it found all three at the first part of the installation where I have to chose a primary device.I can't get my WLAN card working, neither do I get my PCMCIA LAN card working. The third card, this PCMCIA card, has worked on Ubuntu Desktop using another laptop. And as said, the setup finds all three.
I just loaded 10.10 on an Acer Aspire One D255. When I installed Ubuntu, network manager loaded and I was able to use both the wired and wireless cards. After I used update manager, the kernel was upgraded, and I also added some wireless applications (RutilT WLAN Manager, SWScanner, and WiFi Radar). Upon reboot, the network manager doesn't work, and it cannot find any of the devices.

View 2 Replies View RelatedThis may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.
View 4 Replies View RelatedWhat I am trying to do is the following: I have many IBM MT-M 6223 towers (Intel Xeon processor) that need to run a certain Fedora 9 configuration. It is working on one box, now it needs to be replicated on all of the others. What is being done is the working box is cloned, and then that image is loaded on all of the others.These boxes have 5 total Ethernet devices. There is one on-board port, and there are two 2-port expansion cards for a total of 5.
There was one initial problem out of the gate that has since been solved (or perhaps not completely). What was happening is that the boxes that received the cloned image had their Ethernet devices misnumbered. Instead of eth0 through eth4, they were numbered eth5 through eth9.This was eventually traced to the following file: /etc/udev/rules.d/70-persistent-net-config. That file contained the original settings from the box that was first cloned. It had eth0 through eth4 at the top with MAC addresses belonging the box that was the source of the cloned image. It looks like this mismatch was detected, and five more entries, numbered eth5 through eth9, got appended to the bottom with MAC addresses belonging to the new box.
Once /etc/udev/rules.d/70-persistent-net-config was deleted, and the machine rebooted, the 5 ethernet devices came up with the correct numbering (0 thru 4). /etc/udev/rules.d/70-persistent-net-config was rebuilt with the correct devname-MAC pairing.
Now for this new problem.... Part of the configuration across all these machines is that only eth3 should have an IP address. It is a static IP address set through the /etc/sysconfig/network-scripts/ifcfg-eth3 file. All of the other devices must NOT have any IP address. They are either not used or used only for raw Ethernet.After clearing out /etc/udev/rules.d/70-persistent-net-config, /etc/sysconfig/network-scripts/ifcfg-eth3 was edited to give the new box its own unique static IP address before rebooting.Sample ifcfg-eth3 file:
Code:
DEVICE=eth3
BOOTPROTO=static

View 5 Replies View RelatedI downloaded the Fedora 10 DVD installation image and burn it to a DVD.The image was good, I checked the md5 sum.When I put the DVD in the drive and rebooted the text based menu appeared and I chose Install or upgrade.The the installer asked me if I want to check the DVD and I entered Yes.The DVD was checked and it turned out to be fine, but after that when I wanted to continue whit the installation the installer reinserted the DVD but it gave a message saying that it can't find Fedora on any drive .Even if just minutes ago it verified the DVD for integrity.And then it ejected the DVD.If I wanted to press F12 to continue it reinserted the DVD and gave the same message.So I can't continue my installation.
The DVD was fine as you can see, checked by me and by the installer itself.Is the installer asking for a CD?? I thought the DVD was for installing.And even better, that DVD was made whit the exact DVD writer which I use for the installation.So it can't be any incompatibility problem between different DVD ROMs or Writers.
The DVD installation is very important to me, because on that computer there is no internet connection.So the DVD is a solution to install a lot of software and actually use that computer, since yum does not work.
I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

One extra piece of info, is that I am sharing a home directory with a gnome ubuntu install. there were a few minor issues i dealt with initially, but i didnt need to change this user's UID like I have had to do in the past so that's good. Each time i open a terminal I get two pieces of output assuming from the bash startup saying something like.URL...I highly doubt that these problems are related, but figured I'd post. Also if someone knows the solution to that as well, that would save me a bit of googling.
I have three raid volumes, md0, md1, and md2. The weekly raid-check cron always causes md0 and md2 to get checked but never md1.
/etc/cron.weekly/99-raid-check
Volumes md0 and md1 are on the same 8 disks. Volume md0 is a small raid1 across all 8 disks for boot and md1 is a raid5 that occupies the rest of those 8 disks. Volume md2 is a raid5 on a separate set of 6 drives. When I check /var/log/messages* I see that every Sunday md0 and md2 get checked but md1 is never checked. However, when I run 99-raid-check manually, all three volumes get checked. There is clearly something different between how crond runs that script and how I run it, but I can't imagine what that would be.
