the connection via wireless lan can easily be established under ubuntu 10.4, but sometimes dhcp fails to get an ip address. is there a way to perform an action (=run a shell script) every time the connection is established? then i could get the ip manually

I've only been using linux for a few days so I don't know all the tricks. I'm pretty savy configuring windows networks however.My adapter is (according to windows) a: CNet PRO200WL PCI fast ethernet adapterLinux says it is a: 21x4x DEC-tulip compatible 10/100 EthernetI do seem to be getting an ip address from the DHCP router, but I cannout ping any other ips or connect to the internet.I've tried a bunch of different options, switching things back and forth, but it still doesn't work, and honestly i don't even know what some of the options mean.
ALSO, if this helps:
paladin:~ # ifconfig eth0
Eth0 Link encap:Ethernet HWaddr 00:08:A1:03:3C:99

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.
I just installed ubuntu for the first time, and I am not very familiar with everything yet but i am trying to connect to my university's wireless network and can't seem to figure it out. These are the directions they provide for linux users:
Use linuxconf Start linuxconf, go to Basic Host Information under Networking and Client Tasks.
Click Adapter 1, and select DHCP.
Click OK and Apply Changes.
Finally, reboot
I tried running linuxconf from the terminal but no such command exists, is there a similar one for ubuntu?
I using ubuntu 9.04. It was connected to the network with the manual IP Settings. Now the server settings have changed and we are supposed to move to Auto Assign IP (DHCP). All the windows machines are working fine, those are connected to network and using internet. But the ubuntu machine is not getting connected. Is there any any additional setting required for DHCP?

So far i have tried:
Code:
But i cant even ping 192.168.1.1 (Network unreachable error). Is it possible that Ubuntu tries to use eth0 (which was connected to a similar /16 before) to ping 192.168.1.1 or is there somethign wrong with my commands?
Also will an AP allow access to the network although i don't have an IP from its DHCP server?
I'm going to load ubuntu server to a computer just for testing and learning. There is one ethernet card on this computer that will only be used occasionally to connect to the internet. This computer will not have any computers or routers connected to it. So my question is, once installed and running, will DHCP just sit quietly and wait for a request or is it going to complain a lot that it is not finding any other computers?

I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

View 9 Replies View RelatedMy ISP finished some 'upgrades' on its infrastructure. The result is that I am having great difficulty in connecting to the internet.
I have 3 operating systems on my box - XP, Fedora 8 and Feota 12.
I connect using an ethernet card, using dhcp. In fedora 12, the ethernet card is controlled be networkmanager. After the ISP completed their upgrades, I was not able to connect. I tried to connect manually using
Code:
There was an error message -
Code:
I read the advice here: [url], and removed all but the important lines.
But even after that neither ifup eth0 or dhclient eth0 works.
In fedora 8, the ethernet card is activated by ifup eth0 in /etc/rc.local. I was able to connect on a couple of occasions, but that too stopped working. I tried both ifup eth0, dhclient eth0, and tried to use the gui( which fires the dhclient command), but none worked.
When I use windows, it takes about 2 minutes to get an ip (earlier it was immediate). Sometimes that doesnt work and I have to click on "repair" whereupon it starts working.
My problem is little different then what I've seen here. I get the same message after inputting network name and password. I click connect and it just pops up again I don't get it. I'm running Ubuntu 8.10 for Ppc (PS3) I get no internet connection what so ever just the same message. The message I get is " authentication required by wireless network " What do I need to do to connect wireless to my router with my PS3 using Ubuntu 8.10? It does connect with a Ethernet Wire. I am new with Linux.

I have been experiencing slight problems while attempting to connect to the internet via a wireless router. I can connect to my router perfectly fine on Vista and I could connect to my friends router while I was in Ubuntu, but I can't connect to my router while on Ubuntu. I've been entering the same code that will work when I'm in Vista, but it wont work while in Ubuntu.

Cool Solutions: HOW-TO: Set Up a SUSE 10 Machine As a Router
I have a home network, with an OpenWrt router operating successfully as DHCP server (using DNSMasq). I'm planning to install LinuxMCE on my main fileserver and in order for this to properly detect devices around the home it requires that it is the DHCP server. That would be fine except that I sometimes power down the fileserver (eg. when my in-laws sleep in the spare room where the server lives) and that would leave me with no DHCP which creates problems (when my in-laws want to get their laptop connected to the internet).
One answer is to get new in-laws which would be OK except that I'm still pretty keen on my wife. Alternatively is there any way to set up a fallback DHCP server ie. the router would check if there's a functioning DHCP server on the network (ie. the fileserver) and if it gets no response it will serve DHCP addresses itself.
Since that time I moved to Archlinux and I love it. I do however run lubuntu live from a USB for my work PC. I am having a problem with it. I think it's okay to post here because the core of the system is still Ubuntu. I don't think LXDE is the problem. I start up the live environment and it says 'wired connection connected' but I can not load any pages or do anything.
I thought it may be a problem with configuration so I copied down (from Windows) the IP, Subnet, Gateway and DNS. I put them in manually and it doesn't say connected any more and still no connection at all. I am unsure what to do from here. I am not really familiar with Ubuntu enough to try much. I tried to 'dhcpcd eth0' but dhcpcd isn't installed. I guess the default Ubuntu network manager has dhcp enabled automatically.
I want to show you this scheme:MyPC -> router -> internet <- router <- Mom'spc I want to connect from my pc to my mom's pc using ssh. The first router doesn't represent a problem, but my mom's router does. Our IPs are both dynamic (anyway, I can easyly know them) and I have opened the port (TCP/UDP) 2100 on the router in order to open a gateway on mom's pc.The firewall is not enabled on the router, nor on mom's pc.
Granted all this, now I should be able to connect to that computer using ssh:ssh user@ip -p 2100 But I can't, I always get a "connection refused".if I do it on my intranet, I can connect without any problem (to others computers, of course, not mom's) What's the reason because I always get a connection refused?
I have a router with 2 IBM Thinkpads connected. One Thinkpad is running Ubuntu, and the other is running XP.
They connect to the router with no problems.
I installed Ubuntu on a Sharp Moebius laptop and plugged in the network cable.
NOTHING.
I have tried pinging the laptop; nothing.
I am not sure where the problem is, because my Thinkpads have no problems connecting to the router, with both Ubuntu and XP
my LAN just suddenly stopped working. we had a power outage, and it just stopped. it will still recognize the network, but it wont connect. i was experimenting with setting up a web server (trying to set it up on the standard distro). i know its not the network card (on board) because i can put in my pci card and it still wont connect. it will connect when in the live environment. i thought that maybe it had updated, so i tried to boot from a different (older) kernel. that still didn't help.
i stopped apache. i was experimenting with portforwarding at the time (i had everything else working on my server), but i could not get it to work. after this happened, i restored the original settings on my router. i had applied the settings only a day before the power outage. everything still works on another computer on the network (also running linux). (all computers run 9.10) its almost like my router won't assign me an ip address.
I have a new belkin N1 router which I tested in somebody else's flat. It worked fine. When I got home I reset it by pushing a paperclip in the hole for 10+ seconds to erase this flat's internet connection settings (username and password and stuff). After this I plugged it the computer and tried to connect to it (wired connection) using 192.168.2.1 (this is correct for that router, it is not 192.168.0.1). But the browser says it is offline and cannot connect. The lights of the router cycle, the "modem router" light blinks continuously and the others briefly come on and go off again, every few seconds. I tried resetting it again, several times, leaving it off for a few hours, leaving it on for a few hours, etc.
View 2 Replies View RelatedI recently just upgraded my operating system to Ubuntu 10.04 LTS and I can't seem to get my wireless card to connect to our new Verizon Actiontec router. I am using an Encore Electronics 802.11n Wireless USB Adapter (model: ENUWI-N), which had worked with an earlier version of Ubuntu and our old router. The adapter recognizes the SSID of the new router but will not connect with the correct WEP key or even with the encryption turned off. I have tried deleting the wireless profiles and manually re-creating them and still no dice. I have also gone to the website of the chipset manufacturer and found the latest drivers (RT2870USB(RT2870/RT2770)) for the adapter, which, according to the Synaptic Package Manager, I do not currently have installed.
Where do I go from here? Do I need to install the new drivers, and if so how do I do that?
I wanted to try Ubuntu again but have gone wayback to an old 8.10 disk because I couldn't get 10.10 to work. The install with 8.10 went fine but the internet will not connect. The network manager shows eth0 grayed out and when going in to manage the connection it says 'never'. I'm using Vista with a broadband modem connected to a netgear router.
