Networking :: Router And Other Clients See Box But No Internet?

Jul 1, 2010

I'll state the issue and then give whatever extra details are needed. I'm running Ubuntu 10.xThe Linux box is connected to a router via ethernet. That Linksys router is bridged to an AT&T router.The bridging is working fine. The AT&T router's page shows the IP of the Linux box and lists it as a device. The Linksys page shows no errors with packet transmission and receipt. I can ping the Linux box from any client on the AT&T router, and can ping the AT&T clients from the Linux boxI had set the IP of the Linux box to192.168.1.201 while configuring that router, as I had set that router to 192.168.1.200 and it just seemed orderly.The network preferences show eth0 being set to auto dhcp, but the IP is still set to .201 so I don't know that it actually released or renewed.

Ubuntu Networking :: DHCP Clients Table In Router Is Dropped

May 23, 2011

when I change the hostname on my Ubuntu server, the DHCP clients table in my router is dropped.I'm running 32-bit Ubuntu Server 10.10. My router is a Linksys WRT54GL with firmware version 4.30.15. I'm changing the hostname by modifying /etc/hosts and /etc/hostname. I've also tried changing the hostname using the Linux hostname command in a terminal, but this does not seem to behave correctly according to the manpages (it does not actually change the hostname, or update either of the aforementioned files).

I've also tried using a different router - a Linksys BEFSR41 - but the DHCP table is still dropped when I change the hostname on my server (although this router is not all that different from my other one).

Networking :: Set An Internet Bridge For Windows Clients?

Jun 18, 2009

having trouble connecting to many websites due to recent actions of the Iranian government on banning a lot of websites.That's why, I decided to make my computer act like a bridge for their computers, so that they can surf the web using my Internet connection in US. I have Arch linux running on my desktop. I tried to install OpenVPN based on the instructions at ArchWiki page, but I had no success. I guess OpenVPN is too much for what I want to achieve and ArchLinux repositories don't have all the necessary packages to configure it based on some posts I read.

Ubuntu Networking :: VPN Server Does Not Allow Clients To Access Internet?

Jan 7, 2010

i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.

i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.

here is what my setup looks like:

Code:
root@r31495:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:1c:c0:c7:13:35
inet addr:94.23.197.XX Bcast:94.23.197.255 Mask:255.255.255.0

Networking :: Setting Up A VPN For Windows Clients To Reach Debian Server Over The Public Internet

Jan 30, 2010

I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet. I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.

Ubuntu Networking :: Connected To Router But No Internet?

Feb 21, 2010

just installed Ubuntu Netbook remix on my acer aspire one, and come across a problem Ive never faced before. Im able to Connect to my router (and access it through the internal ip address) but as soon as i try access anything outside of my network there is nothing!

This i found odd as first i thought it might have just been my Routers problem, but seeing as all my other computers were connected to it with no problems (wired and wireless) I quickly traced the problem back to the laptop.

After this i decided to see if after a simple update would fix the problem. so i connected it up through the Ethernet port once again it connects to the router but no internet! I have tried everything in my knowledge, but with no success!

Ubuntu Networking :: Router Not Working/ Can't Get To Internet?

Apr 29, 2010

I am trying to set up a basic router. I am running ubuntu server 10.04(just installed it today!) I have a verizon aircard(mobile broadband card) that is connected via usb. I am using wvdial to "dial-up" the connection. This works just fine and gives me a device on ppp0. There is a single lan connection on eth0 set up as a static ip address under /etc/network/interfaces. I don't even have any firewall running yet. For whatever reason, I can only get out on the internet when eth0 is set to get its ip address through dhcp. When I set it up with a static ip, I get for example:

$ping 4.2.2.2
From 192.168.1.1 icmp_seq=1 Destination Host Unreachable.
$ping google.com
ping: unknown host google.com

If, however, after I have booted and the wvdial has been started, I set up eth0 as dhcp, run /etc/init.d/networking restart, set it back as static, run /etc/init.d/networking restart again, all work well. When I reboot the system with the static ip on eth0, and connect to wvdial, I get no internet again.

Ubuntu Networking :: 10.04, Internet Not Working Through Router

Aug 20, 2010

My internet works fine if I plug directly into the modem, but if I go through the router either using ethernet or wireless it doesn't work. I can access the router perfectly when using wireless and change settings and all that but cant access the internet. From what I've read it isn't a DNS issue because I cant get a result from pinging an ip, so I think it may be something firewall related but I'm unsure.

Ubuntu Networking :: Internet - Router Disconnecting ?

Feb 14, 2011

My router is a Netgear router with Comcast, and after going on Ubuntu for a couple hours just doing normal things, the Internet disconnects. Then I have to restart my computer and start everything over again. I check the router and everything seems to be fine, I even unplug everything on the router first (like I am instructed to do so if this sort of thing happens) to make sure that's not what is causing the problem. It has to be the Ubuntu system.

Ubuntu Networking :: Can't Use The Internet With Linksys Router

Feb 25, 2011

I am dual booting XP and Ubuntu 10.10 64bit on a Dell Latitude E6410 and I have a Linksys WRT120N router connected to my Modem.

So the weird thing is, under XP I can use the internet while connected to my router. Under Ubuntu I can't use the internet while connected to my router. But I can use the internet in Ubuntu if I connect to my neighbor's router called "linksys". So something happens when I connect to my router that makes Ubuntu not able to access the internet. But if I'm connected to my Neighbors router or if I use XP while connected to my router I can use the internet.

I have been using Ubuntu for about a year, so I'm getting better but still a noob. I've tried to figure out what's going on by looking at other forums and posts and trying to see if anyone has solved this. So far I've had no luck. This is also the first of many problem I have encountered that I have been unable to solve using online posts, and is the first problem that I have had to resorted to creating a post to try and fix.

Ubuntu Networking :: Connected To Router But No Internet

Sep 1, 2011

I'm running a Natty machine wired to a TP-Link router (TL-WR841N) with additional Ubuntu and Windows machine on WiFi. Recently I've had some problems with connectivity on the Natty machine. Connectivity is fine as far as the router, but not beyond it. This applies to all browsers, Software Center, Aptitude and anything else you can think of. Now, normally at this point I would call my ISP, but the thing is, all other machines have connectivity. I've checked the cables twice and anyway, if it were them, I wouldn't be able to ping the router. Router has ping functionality to outside and it's working, have tried ubuntu.com and google.com. Also, connectivity between the wired and wireless machines is fine, pings are flying across the network beautifully.

Networking :: Connect To Internet Through A (wireless) Router?

Jul 30, 2010

I connect my internet using pppoe to may DSL modem with bridging mode, and it goes fine until I try to put a wireless router between my PC and the modem. After I configure both modem and the router, I can run my wireless network fine by connecting it from a laptop, but my PC is unable to reach the modem at this configuration.

PC has address 192.168.2.100
Router has address 192.168.2.2
Modem has address 192.168.2.1
all with netmask 255.255.255.0

With bridging configuration in modem and automatic detect configuration in the wireless router, the wireless network run well, except the PC cannot ping the Modem saying that

Code:

root@firefly:~# ping 192.168.2.1
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.
From 192.168.2.100 icmp_seq=2 Destination Host Unreachable

Looks like my PC, which has Slackware 13.0, don't know how to reach the modem even they are physically connected.

1. how can I configure the modem, PC, and router so that the PC can reach the router? Do I need to do add route gateway from the PC?

2. How can I configure internet connection from the PC (before I use PPPoE)?

3. How can I configure the modem, PC, and router so that the wireless network is on?

Networking :: Internet Is Very Slow With Slackware 13 Router

May 16, 2011

I just installed and configured Slackware on an old computer I am using as a router.

The internet works fine on the slackware box (router) but all of the computers behind it are having issues. When browsing, some websites work perfectly fine, while others are slow to load, and a few don't load at all. I'm not really sure where to start on diagnosing this, so any help would be appreciated.

Also whenever I restart the computer, I have to use this command before the DHCP server will start. What do I have to do to get it to start up with the computer?

Ubuntu Networking :: Control Internet Traffic Without Router?

Jul 27, 2010

I have a desktop, a laptop, & a wireless router. The router, unfortunately, doesn't support dd-wrt, tomato, etc firmware, but I would still like to prioritize voip/web browsing over bulk Internet traffic. I hope I can offload the router's missing QoS to my desktop.

Is it possible to have the laptop's connection go from the wall to the router to the desktop, where the desktop could perform the QoS of tomato, then continue on to the laptop? I'm a bit of a noob to networking (subnets?) but do well enough following good instructions.

As for the program that would do the QoS... Don't some Linux machines basically work as super-powered routers for businesses? So there must be some package but couldn't find one. The closest I got was wondershaper but it only shapes traffic for the computer on which it's installed; it might form part of the solution but falls short on its own. other devices should be able to access the Internet normally if the desktop is turned off, & work with other devices like a (jailbroken) iPod Touch.

Ubuntu Networking :: WiFi Router Connects But No Internet?

Nov 11, 2010

trying to run 10.04 netbook live from a memory stick with a view to installing it on my laptop. However although I can see my wireless router and connect to it I cannot access the internet. I have tried this on my laptop and desktop with the same result. I was however able to download Seamonkey browser using the software manager....this also cannot access the internet. Both of my PC's have no problem when using XP or Linux Mint.

I have also discovered that if I piggyback, using Ubuntu 10.04, on a neighbours open wifi link I can gain access to the internet. My wifi is using WEP protection but as I said I can set the link up to the router, entering the appropriate key code, and have a good signal strength, I just cannot access a google search page.

Ubuntu Networking :: CAN Connect To Other Computers But Not Router Or Internet - 10.04

- CANNOT get internet connections - including router at 192.168.0.1
- CANNOT even ping router (but I get an IP address - weird)
- Other computers on the network CAN access internet
- Live CD could not access internet

results of ifconfig

Code:

Code:

I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?

This is the results from dmesg:

Code:

I have tried:

- to set proxy settings as "Direct internet connection"
- disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer
- Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again.
- Uninstalled Crashplan which was the last software that we installed (and it was working ok).

I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).
