Ubuntu Networking :: Final 10.04 Go Wrong On Wireless?
Apr 30, 2010
Let me explain: I had the 10.04 LTS Beta, and upgrading until today. I got the wireless card ( the notorious broadcom ) in the beta by adding the CD to the repository, installing through synaptic ( the broadcom drivers available from the CD ), then selecting the driver from the Hardware Device Manager, enabled, restarted and was online.
I thought the Final version would be just as smooth right? I didn't upgrade because the OS never showed up in the Beta's Software Updates, so I figured to just do a fresh install, my biggest issue with Linux in general was solely it's conflict with broadcom, never anything else. So anyway, In this Final Release, I go to do the same routine, check this out: The card wasn't even showing up this time, wasn't being recognized! In the beta, it atleast showed up. That's minor but would be major to a new guy.
I figured to do the synaptic again, add the cd then the b43cutter( i think it's called ) and succeeded, got the Card to show this time. When I went to add the other driver ( the bcmwl-kernel ) the file that would have the driver to be enabled, it tells me "File Not Found!" don't give me the cop out of "Hook it up to a cable modem and download the driver" bid because that just pisses people off, we don't all have the means to carry around massive PC's to a cable modem.
What I hope to expect is someone telling me to download a file and have it on the desktop then trying it that way because I know about all the other tricks, and I think you can see, I tried em. I'm curious to know why it worked in a Beta release and not now
I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?
I am trying to get wireless network with Dlink DWA 125 working unter Kubuntu 10.04 (kernel 2.6.32-23, 32-bit). I already carried out all the hacks for replacing the rt28** modules by rt3070, which seems a rather common issue. What I did is described here:[URL]..Now output of usb-devices is:
One rather silly question (excuse me, never used wireless before):Is the WPA key the 10 digit hex-number labeled "network key" on my hardware ? At least I entered this one under Windows and it worked instantly x( . Even if something is wrong here, I expected some error messages. I feel I got pretty close, but I still need some help for the last few steps. Please give me a tip what might help or how to get some useful error information.
These problems just started the last couple of days but I have been using Lucid 10.04 for a month now. My wireless Signal varies in strength wildly. I sitting at home, not 20 feet from my router. I never had these problems before Ubuntu Lucid Lynx 10.04. I am running both Network Manager and Wicd.
Errors: 1. Wicd states "Wrong Password" which is not true. 2. Dropping off-line for no reason, sometimes 3 or 4 times a minute and sometimes it works fine for hours. 3. Firefox 3.6.3 Automatically Checking "Work Offline"!?
[Code]...
I have the Proper Wireless Drivers. I have not changed my wireless settings, channel or WPA for 8 months now so I know thats not it.
A couple of days ago I asked why my pc changes the wireless card name.It switches between AR9285 ( right) and AR5008 ( wrong). Well, it is not the case. When system identified with AR9285,it loads ath9k and I can connect to the router. When system identifies my card as AR5008, no kernel module is present at all ( lspci -k). The wrong card name occurs only when system rebooted. If I gracefully shut down the system, it always comes up with a right name for the card( AR9285). So, how to force the system identify my card right no matter if I reboot or shut down?
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
my network expertise is tenuous at best. This started because one computer on my network is having trouble updating Google Toolbar information. This is a laptop which joins other wifi networks outside of the house.
I updated Kubuntu from 8.10 to 9.04. After the update, I saw a problem with VPN connections. I am using an mac pro with 2 ethernet ports. Only one of them is connected to switch. I am using a static IP in my local network. The problem is that I lose dns information after connecting and disconnecting to a VPN by KVpns.As I am using static ip, I entered my dns server to resolv.conf file with "nameserver 192.168.128.4". My interfaces file is as follows:
Well why all my ips are getting the speed I mentioned in delay pool, even 192.168.0.134, as I have excluded it in delay pool. what is wrong with the configuration. I want 192.168.0.134 to get maximum speed available, while rest of the network goes with the mentioned speed.
I'm trying to connect to my windows 7 computer via network from ubuntu 10.04. I get as far as this screen:
My problem is it always says I've entered the wrong password. I've tried the administrator account password and also the long windows 7 homegroup password.
I'm running a fresh install of Ubuntu 10.4.1 on a Dell Dimension 4700 desktop.When connected to the network (jack in wall, no router), I normally navigate my intranet and the internet.But here's the issue: this particular Dell machine has an IP addresses that is radically different from all other machines connected to the same network.I have tried to edit etc/network/interfaces to force a different IP, but then I lose connectivity. I need this to follow the IP scheme of my intranet so I can set up a server that resolves by hostname. Is there anything wrong with the NIC or is this something that can be resolved via command line?
yesterday a tried to put Ubutnu 32bit insted of 64bit to try differences, but I have a little problem with some web fonts For example on facebook are texts messed... and it is same on a couple other websites, which has nothing common. (School pages, wordpress administration...) Fonts are wrong in all web browsers, but each browser shows them different. for example Facebook in Opera (text is messed) and login page in Firefox(text is missing...) So i think, it is not a problem with browser.
On a server with 4 network interfaces, sometimes not all 4 are plugged in. All 4 interfaces have the same IP address. Sometimes the machine cannot access the local LAN, but can access the internet via a router on the local LAN, after a reboot. What I find is that the routing table looks like this:
Code: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2 172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3 0.0.0.0 172.30.0.2 0.0.0.0 UG 1 0 0 eth0 0.0.0.0 172.30.0.2 0.0.0.0 UG 2 0 0 eth1 0.0.0.0 172.30.0.2 0.0.0.0 UG 3 0 0 eth2 0.0.0.0 172.30.0.2 0.0.0.0 UG 4 0 0 eth3
On the console I cannot reach any local host, but I can reach internet hosts. Pinging the gateway router 172.30.0.2 gets no answer. When I manually change it to this: Code: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.30.0.0 0.0.0.0 255.255.0.0 U 1 0 0 eth0 172.30.0.0 0.0.0.0 255.255.0.0 U 2 0 0 eth1 172.30.0.0 0.0.0.0 255.255.0.0 U 3 0 0 eth2 172.30.0.0 0.0.0.0 255.255.0.0 U 4 0 0 eth3 0.0.0.0 172.30.0.2 0.0.0.0 UG 1 0 0 eth0 0.0.0.0 172.30.0.2 0.0.0.0 UG 2 0 0 eth1 0.0.0.0 172.30.0.2 0.0.0.0 UG 3 0 0 eth2 0.0.0.0 172.30.0.2 0.0.0.0 UG 4 0 0 eth3
Then all is well (can ping local hosts including the gateway router). I do have metric specified in the /etc/network/interfaces file like this: Code: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 172.30.16.8 netmask 255.255.0.0 network 172.30.0.0 broadcast 172.30.255.255 metric 1
I have a peculular routing problem on my hands. I have a server running in my office. it has various services running on it (httpd sshd etc.) in order to access these services I have a domain name pointing to my IP.If I try to connect to the server from an external IP, all is fine and working as normal.However, if I am connecting from the interal lan to the server, my domain name resolves to the address of the routerSo for instance everywhere on the interent my domain name resolves to the correct external IP (12.23.34.45) which is then connecting through my cable modem (12.23.34.45) to my router (192.168.55.66) and directed to my server (80.80.80.80)however if I resolve my domain from within my lan, I get my routers ip 192.168.55.66 so trying to connect to my server times out while connection to the wrong device.My network setup is very simple. nothing fancy.I think I'm using google's 8.8.8.8 for my dns server
When i insert the Live CD, whether I choose memory test, try without installing or install Ubuntu, the computer seems to continue to load without a signal going to the monitor, as if a frequency or resolution unsupported by the card or monitor was chosen.
I had a similar issue with 9.10, but this only happened after the system was installed when you got to the login screen. I can't find a 'safe graphics' option on this live CD as I could on Karmic. Are there any cheat codes I can use to enable some sort of safe graphics mode?
I am downloading the alternate installer now and going to try installing using this method. I've never done this before, do I have to setup a desktop myself using the command line with this? My computer is an Asus M2N-SLI Deluxe motherboard with 2GB RAM, a GeForce 9600GT graphics card, and a DGM 23" 1920x1080 widescreen monitor connected via DVI. Also I am installing the 64 bit version, although I don't reckon this is a 64 bit only issue.
Somehow I've been really unlucky with Ubuntu 10.10. When I run the CD choose any of the three options offered by Grub, the system just waits for 20-30 seconds and gives me a screen with Green squares.
Here's a video I made when 10.10 was in beta. The problem is still the same even in the final version. http://www.......com/watch?v=KKiks45jMEU
I have an Intel Dual Core 2.0Ghz PC with 8GB ram and an Nvidia GeForce 6200 graphics card. I have Ubuntu 10.04 on it which installs and works fine. its only the 10.10 that I have this problem with.
With a fresh lucid install on my new dell mini v10 when I'm connected to the internet the wrong icon is displayed on the panel by nm-applet. The no connection icon with the red exclamation mark is displayed when the normal wireless network connection icon should be shown. By the way I'm using the proprietary broadcom drivers for the wireless
I have a ZTE 3G USB modem (MF645). When I plug it, 5 devices appear: /dev/ttyUSB[0-4]. The modem device is /dev/ttyUSB2, and I can successfully connect wvdial on it. NetworkManager detects the modem, however, it tries to connect to /dev/ttyUSB1 instead, and fails.
How does NM decides which device to connect to? Is it possible to instruct it to connect to a specific device?
I've had a Samba share set up for awhile now on my Ubuntu 10.04 server. Now I'm trying to create separate shares for separate users. When I started, I was logging in from my Windows box where I was Tony, and the only user on my 'nix box was htpc. I had the majority of my file permissions as open.
Now, I've created new users on the server, including Tony. But when I open a Samba share from my Windows computer, it does so as htpc. This is not a setting I ever put anywhere. I don't care about specific user names, but I want to have a folder that only I can access from my Windows box, and for someone else to have a folder only they can access from their Windows box.
While running some live tests last week I saw an odd situation where netstat appeared to be displaying the wrong PID and process name for TCP connections. I'm trying to figure out if this is just a strange netstat bug or if it could indicate something odd is happening with our software.
We have a main program which establishes a number of connections, including connecting to a JMS server and listening/accepting a TCP connection. The main program also creates a child process which it uses to communicate with another server. On at least three occasions we saw a situation we saw netstat reporting all the expected TCP connections (correct ip/port for both source and destination), however the child process, instead of the main, was listed for the PID. The main process was still running but netstat no longer reported any TCP connections established by the main program. The main program continued to function correctly, the JMS communication continued to work and we believe the other TCP connection was functioning correctly despite the program supposedly not having any TCP connections.
I'm wondering if this could simply be a bug and/or obscure functionality of netstat that I don't understand which would cause netstat to report the child process as 'owning' the parents TCP connections. I don't know how this would happen or why the parent would continue functioning despite the problem otherwise.
I'm trying to get dhcpd to use a specific IP address as the source address for responses it uses an IP address for. I coded "local-address 172.30.0.4" in the config file. For some responses it uses this address. For some other responses it does not. In those cases it uses the IP address that is the first on the interface. Is there another configuration I should be using, instead?
I'm not too sure if this is the right topic to post in but if it isn't please move it to the correct topic. I recently opened some ports for my Playstation 3 and the connection test on the PS3 tells me that the ports are open . But when I execute this command
nmap -p 0-60000 192.168.1.5 I get this
Quote:

I could be executing the wrong command or something but I have read through the manual and couldn't find anything that helped. I have tried this command on other machines that I have opened ports for and get similar results except for a few Ephemeral ports (80,443 etc.) which also makes me wonder why these aren't listed as open on the PS3?
When I boot my computer (Ubuntu 9.10) /etc/resolv.conf is written as:# Generated by Connection Managernameserver 10.33.8.11 10.33.4.136However, if I try to do anything from the command line, I get an error like:host: parse of /etc/resolv.conf failedI then need to edit /etc/resolv.conf to:

eth1 which is connected to interneteth2 internal networkbecause the server is part of a complicate network i need to setup the routing tables for eth1 and eth2but i need that the default 0.0.0.0 must be read from eth1 while i dont know why the server first read the one on eth2. this creates big problem to me.if i add the default route to eth1 i get an error saying that the default route already exist (i suppose is the one on eth2)how i can solve this ? i must create a script that first delete the default from eth2 and after add it to eth1
I would like to be able to install firefox without installing the "pre" version. I don't like running beta software for my primary browser. I already installed Namoroka, which is 3.6.1pre. Is there a repository I can add for this? I will already have to remove one of my repositories and remove firefox.
I'm interested in trying out the 10.04 beta release. Does anyone know if it will be possible to upgrade from the beta to the final version once it is released in April? Or will I have to perform a fresh install of the final version?
