Ubuntu Networking :: When Rebooted Router Via SSH My Personal PC Did Not Renew IP
Apr 30, 2011
I have a Natty installation that I just did yesterday on my personal PC. I am not home currently, but I can access my router (uses DD-WRT), and my Media Center Machine (Ubuntu 10.10) via SSH. For some reason, when I rebooted my router via SSH my personal PC (with Natty) did not renew an IP.Is there a way I can use magic packets or any other method from my other Ubuntu machine that I have remote access to, to force that other machine to renew it's IP?

I installed Ubuntu 11.04 and then I installed WICD using Synaptic and then uninstalled Network Manager. WICD worked fine until I rebooted. Then I could not connect at all. Wicd displayed the wireless lans and even authenticated OK. But wicd was not able to obtain an IP address.

When there is a power failure at my university for about 30 minute, my computer stays up because of a UPS, but the switch it is connected to via ethernet is reset. After this, my machine loses network connectivity until I manually select the network using nm-applet.
In System -> Preferences -> Network Connections, the network has the "Connect automatically" box checked.
However, in /etc/NetworkManager/nm-system-settings.conf, there is a line that says:
Code:
no-auto-default=00:30:48:b0:11:07,
and that is the MAC address of the ethernet card.
I'm running Ubuntu jaunty.

I have been running Meerkat in its various forms for the last few weeks. Wireless connection has not been a problem at all. I rebooted about 15 mins ago and on restarting the wireless connection will not connect. I checked to see what the problem was and clicked on Edit Connections and on the wireless tab.
My wireless is set to auto and its name is SKY 24550. I now have 2 entries in the same name and the one that is trying to connect is asking for wep 128 bit security details to be entered. My connection used WPA&WPA2 personal.
Ok, I thought I'll delete the new one (with the different security setting) and try again.
No good, it still asks for the same security details.
So I go back into edit connections and the new one is back again! I can't get rid of it, and while it's there the one that should connect isn't getting the chance.
Fortunately ethernet is working ok and I also have a Natty install which also connects ok through the old wireless connection, but not in Maverick.

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

I have a dedicated control computer that can only be accessed with web-browser (with its ip-address). My DHCP-server gives a static ip-address to the control computer (base on its mac-address). Somehow and after some time the control computer looses its ip-address (can't ping to it any more) ... and then I have to reset the control computer to get it to pick up the ip-address ... this is not a good solution since the control computer is not nearby. is there a way to force the control computer to renew its ip-address based on its mac-address

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'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

Valid static(public) IP set of 2:
IP:xxx.xxx.xxx.147 & 148 (eth1, eth2)
Subnet:255.255.255.240
i want to run xxx.xxx.xxx.147 as a web server & xxx.xxx.xxx.148 as a ftp server. but I'm able to ping only xxx.xxx.xxx.17(WAN IP) from outside world. Can any1 tell me that how can i bring my 147 & 148 IP online without router.

I will be staying somewhere that uses WPA encryption for their wireless network. It's a hidden wireless network with the security type being WPA-Personal the encryption type being TKIP.The connection works while in Windows7but not in F12.I edited the /etc/wpa_supplicant/wpa_supplicant.confthe default information already provided for WPA connections.Then, as su, I ran:
Code:
wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf
And the output was:

I was using Fedora 14 for some months and my wireless was working fine. I've set up a hidden network with WPA2 Personal authentication. My laptop has an Atheros AR2413 802.11bg NIC and my modem/router is a Topcom Webracer. Yesterday I upgraded to Fedora 15 and I can't login to that network now. The only way to login again is to boot with the old Fedora 14 kernel that still shows up in my grub menu.I've searched this on these forums there are plenty of people with the same problem but the only suggestions are that the network card isn't supported by Fedora or the network card doesn't support 802.11bg.some suggest changing the authentication method in the router... and the only one who got it solved was by rebooting the router... None of this addresses the fact that the same hardware/network was working just fine in Fedora 14. And I still can't find a way to have a wireless WPA2 connection with Fedora 15.What can I do to fix it?

My wife and I activated the 'Personal File Sharing' on our two Fedora #9 laptops. We can exchange photos and text files via our "public" folders, just fine. Entire setup took less than 20 minutes. We have not been able to get the Fedora #14 version of 'Personal File Sharing' to work using same, online and 'in system', help directions for both the F#9 and F#14. After four eves of looking I have not found any more detailed, install/activate help files anywhere. I can't ask my system manager because that's us. At this point the only thing I can think of is that there may be some part of the F#14 security structure that needs to be addressed and tweaked.

I updated to the latest version of Ubuntu and before I could connect to the network "krafft" that is a WPA2-Personal protected network.If I go into Windows and change security to none I can connect with Ubuntu, but not when it's protected.After a bit of time logged in without network a dialogue pops up and looks almost like this :but "Focus" is replaced with "krafft" and the password is something else.I know that the password is right and the network worked perfectly before update.I got an USB wireless network receiver from D-Link and the chipste is ralink rt2870.In the previous Ubuntu distribution you had to write "blacklist rt2800usb" in /etc/modprobe.d/blacklist.conf but it won't work with or without that blacklist.When I updated I saw some message about the network manager(at least I think so) so maybe the problem is in that.

I'm using 10.04 beta...
If I go to system - preferences - personal file sharing, I cannot select "share files over the network." The panel is greyed out and the message "This feature cannot be enabled because the required packages are not installed on your computer" is shown
It ever so usefully doesn't tell me what those packages are though! - It'd be nice to have more useful error messages or the ability to click to install them...
Anyway, what do I have to do to get this going again?! I've installed everything to do with samba, webdav that I can find but still no cigar...

I'm currently working with wireless network kernel module.
This device initialiy gets its IP address by using DHCP,
but the problem is sometimes the new IP assigned for internal reason.
So what I want to do is assigning new(changed)IP address into exsiting
interface, or occuring DHCP renew event to cause update IP from kernel
level. This shold be done without user's intervention, so whenever the
kernel module detects IP changed(via underlying wireless
communication), it automatically correct update its IP address.
Q1) any functions or api to cause DHCP renew event from kernel level?
Q2) or any functions or api to assign IP address to specific interface?

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

My son lost his USB Wireless stick for his Computer. 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.

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.
