I can not connect via a 3g card (Huawei). It connects on the GPRS and then disconnects, then connects to the GSM and disconnects. Both do so after 5 seconds connection at max. Someone suggested that I update, but I can not connect to internet and the version I am using is Ubuntu 10.04.Checked all the settings with my ISP and all is good,including pin etc.Nothing they can do from that side, and claim that it is a Linux problem.I am sure that they just cant be bothered. It works just fine on XP.Not sure what can be done to fix.
I have a system with windows xp, and to connect to internet I use a usb card EVDO (brand ZTE) given by my provider (BSNL India).Now I installed ubuntu 10:04 but I do not know how to make my usb card work to connect to internet (the provider gave the software only for win xp)
I'm trying to set up a shared Internet connection that had been broken by a previous update, I believe. Eth0 is connected to the Internet, whereas eth2 should be the connection going to my Roku set-top box. Under the nm-applet icon, an entry exists for "Auto eth0" for the first card, but there is nothing under the second card except "disconnected". How do I make a connection entry under my eth2 card so that I can share my Internet connection with my Roku box?
Im living in a student-city where we get one internet-cable in the wall each, if we need more we are told to use a switch. But, since ive got some tech that depends on wifi, I was wondering if its possible to setup my ubuntu to work like a sort of wifi-switch?
Basically, Im not allowed to set up anything that resembles a router..(so no dhcp) all i need is what a switch would do, only wireless and wpa/wep would be very nice
Atm ive got my cabled network plugged into my onboard ethernet-port, and ive got a d-link DWA-556 (Atheros AR5008 I think) wifi card that i wanted to use to share my connection. is this doable?
I use Ubuntu 9.04 and try to get a Sweex LW053 USB wireless card (Ralink RT73/RT2500 chipset) to work. According to the Wiki list in the sticky thread, this one should work "out of the box" since 8.04.
lsusb delivers Bus 002 Device 002: ID 148f:2573 Ralink Technology Corp. RT2501USB Wireless Adapter and there is also some wlan0 entry that doesn't look too dodgy when typing ifconfig. From this I get that my laptop recognizes the card. I also typed in some numbers such as SSID and DNS server address in Preferences>Network Connections where asked (although the information that I had wasn't 100% what was asked for so I tried to guess what needs to be filled in which fields). However, I don't get an internet connection (Firefox can't find server...)
I have a very strange problem with my Linux Router/Firewall machine where i keep losing my connection on the ethernet card.
I have installed a Debian 4 distro on a PC with 2 nics to create a router/firewall machine. On nic-1 i have connected the ADSL modem and on nic-2 a laptop for testing.
What i want is to build a DMZ with public IP addresses assigned to the servers in DMZ.
Schematic example:
Code:
We have a total of 16 Public IP's assigned to the ADSL modem from our ISP configured in routering mode. Unfortunately our new ISP does not support Bridge mode, otherwise i would not have this problem. (we had modem in bridge mode working fine with our old ISP, but they have stopped so we were forced to switch to another ISP. eth1 and eth2 both have public IP addresses from the modem set hardcoded in the /etc/network/interfaces on Linux pc and on my testlaptop in the DMZ (server-1) i have set another public IP (they all fall in the same network range) I have enabled IP forwarding on Linux router/firewall and for testing the firewall is set to allow all traffic.
When i try to ping the testlaptop in my DMZ from a remote machine outside in our datacenter i get no reply.
However when i run the following command: ip addr add xx.xx.xx.xx dev eth1 to assign the public IP i have chosen for the laptop to the inner nic (eth2) and then try to ping the testlaptop again from the remote machine it still does not reply ... but (and here is the most bizar thing)...
When i then run the following command: ip addr del xx.xx.xx.xx dev eth1 (where xx.xx.xx.xx is the ip of the testlaptop) and try to ping again from the remote machine then it seems to be working fine ... however only for a short time because then connection is lost somehow.
I am trying to figure out how I can see which access point my wireless card is connected to. I have a slackware system and. Basically, I know my card is connected to something, because firefox can do a google search, but I'm not sure what network it is connected to, since there are a couple open networks in my apt complex. Is there a command to list the ssid? that I'm connect to? and, I'm new to all this so I'm not sure if ssid is the correct term. I have a consumer grade netgear wireless "router" that I bought from bestbuy which has a "passphrase".
Ok, so I upgraded my acer aspire one to the new Ubuntu 10, and at first everything was working fine, except the audio. Now, for some reason, my wireless and ethernet ports have died. I can't get online by either method. I can do ifconfig <device> up and it will show up if i do iwconfig or ifconfig, but the wireless isn't associated with the AP. Currently I'm trying to load some drivers for my atheros card, and we'll see how that works outReally I was wondering, how come the modules don't load at boot time, and how can I fix this? I've been a Linux user for quite sometime, however I've been more of end user
I'm using RedHat Linux. In my friend system have Winxp. I have 2 LAN Cards. I'm using wired Broadband internet. So i want to share my internet connection to my friend system through another one LAN card. How can i do this
I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
I'm running Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
I recently installed Xubuntu on my old P3 laptop (Compaq Armada E500 if anyone is familiar). The laptop is a bit old, so both wired and wireless networking is done via PCMCIA cards. I have 2 cards installed, one for each purpose. I can't find the dongle for the wired card right now, so I am trying to use the wireless card. I am able to find the network I want to connect to, and type in the password since the network is secured. It tries to connect but then pops up again asking for the password (I know it is correct). Is this card supported by linux/compatible? I tried finding drivers online but the sites that had drivers were down.
Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.
Since few days, I have a problem with my wireless card on some access points. For example I try to connect on WPA2/PSK AP and there are 7/8sec between dhcp discover and dhcp offer. After getting an ip address, ping between my laptop and AP is ~100ms.. AP is near 1m. When trying to ping google.com, 80% packets lost and latency is ~ 400ms.
I have a trace in /var/log/syslog when I connect :

When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
Unfortunately, due to the layout of my new apartment I'm going to have to run my desktop PC with a wireless card instead of a wired connection.
Googling turns up a lot of out-of-date information on hardware compatibility for Linux and PC wireless cards. Could anyone provide a suggestion or two for known-good, 2.6-kernel compatible PC wireless cards?
I'm dealing with two dedicated servers hosted at liquidweb. The basic idea is that one machine might not be enough to handle the traffic at launch so we have a second machine to shoulder the MySQL duties -- it seemed a natural way to divy up computation burdens.
The support staff at LW tells me that each machine has three network cards
1) Public-facing NIC through which all public visitors are served
2) NIC on LAN so that liquidweb can access the machine locally for maintenance and support
3) Third NIC so that the two machines can speak to each other rapidly on their own private network. Apparently the two machines are connected via crossover cable.
It's my understanding that machine 1 has IP of 192.168.0.1 on this third card and machine 2 has IP of 192.168.0.2 on its third card. For some reason, these machines cannot speak to each other using ping, telnet, ssh, http, or MySQL.
I've contacted tech support about this issue but was wondering how I might be sure that the MySQL traffic transits the third network card on each machine. I'm guessing that it's just a matter of using the third card's IP addresses but want to be sure. Is there any way to specify a NIC when connecting via MySQL?
I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code: pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error pppd[4104]: Cannot determine ethernet address for proxy ARP in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?

I performed an update that has caused issues with my wireless. Errors relating to wireless firmware missing and consequently no internet connection.
I've been through this before with my 2008 macbook air BCM card whose firmware isn't included in installs. In the past I've manually installed the b43-fwcutter package an extracted some firmware... That doesn't seem to be working here.
I've used [URL]i ... cefirmware to troubleshoot. I have not been able to get b43 or wl to work.
I attempted to install the "firmware-b43-installer_015-14.1_all.deb" package; however it depends on wget to download and install "broadcom-wl-5.100.138.tar.bz2" from wlfinger.com.
So I manually installed b43-fwcutter and used it to extract the broadcom-wl-5 file referenced....
modprobe wl says wl doesn't exist and modprobe b43 doesn't seem to work.
Code: Select allsudo dpkg -i broadcom-sta-dkms_5.100.82.112-8_all.deb Setting up broadcom-sta-dkms (5.100.82.112-8) ... Loading new broadcom-sta-5.100.82.112 DKMS files... Building only for 3.2.0-4-amd64 Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed.
I tried something from broadcom that produced make errors "/lib/modules/3.2.0-4-amd64/build: No such file or directory"... I think this means I need some kernel development packages, broadcom says:
Code: Select allOn Fedora install 'kernel-devel' (Development Package for building kernel modules to match the kernel) from the Package Manager (System-> Administration-> Add/Remove Software).
On Ubuntu, you will need headers and tools. Try these commands: # apt-get install build-essential linux-headers-generic # apt-get build-dep linux
I'm having trouble install this stuff without the net and not sure installing generic headers and build-dep outside of apt-get is the way to go... linux-headers-3.2.0-4-amd64_3.2.57-3+deb7u2_amd64.deb has alot of dependencies that would take me a while to find and download.
