I did a little searching and found some answers, not quite identical but should work, it's supposed to be "easy" using the Ubuntu GUI tools. It'll set up some IP tables / NAT magic (somehow), so we were close with using "route - show / manipulate the IP routing table" but just didn't know the "secret words" On the internet connected computer (server), go to ...

It may arise due to several conditions at which you may require to block or restrict any specific IP address or domain from access of your server. It’s a simple process and by following these instructions you can block the website domain in Ubuntu. As we know Ubuntu is an open source command based operating system that’s why you would have to go through ...

I don't know for certain if this would interfere with updates or not, but immediately I can see that the repeating error is caused by having your update repositories set to include the original installation cd-rom. To correct please open your Update Manager. Click on the SETTINGS button, click on the left most tab "Ubuntu Software" and uncheck the box ...

It seems your repository settings have some problems. Run /usr/bin/software-sources. This program configures package repository. You can see 'Additional repositories' tab. You can uncheck 'cdrom:[Linux' after clicking that tab to avoid "CD-ROM" message. Then, choose 'Official repositories' tab. And choose proper 'Mirrors' with labled 'Main' and 'Base'. ...

I figured out a way to resolve this. This website helped me a lot. That was the scenario I had. Later configured iptables to restrict some client systems to few websites. I configured a ubuntu system as gateway between LAN and ADSL router. Then set rules in firewall (iptables) to restrict source systems (client) to some websites. This website helped me in ...

You use URL encoding. There are several online tools which do the job, or you can look up the hex value of the character and prefix it with a %. So, Gmail@123 becomes Gmail%40123.

Personal speaking, I've made the experience that r8168 works better on various RTL81XX chips than r8169 Packages installed using APT automatically satisfy all dependencies. So everything required is installed when the package is being installed. You need, however, prevent r8169 from being loaded after r8168 is installed. The DKMS installation script of ...

I suspect I know what the problem is. You see, when you installed Ubuntu, you almost certainly depended on that wireless connection for the internet access Ubuntu needs to install properly. It probably worked just well enough to try and fail. Fortunately you probably don't have to re-install. You simply need to connect internet to it via an Ethernet ...

The basic thing to do is to make the squid server the default gateway instead of your Internet router. Just add an additional network card to the Ubuntu squid bringing it up to 2 network cards: 1 into your LAN and 1 into your network router. The LAN-side now gets the IP address of the default gateway (probably 192.168.1.1) and the WAN-side gets an ...

The error message for this problem was correct, the server was in restricted network and did not have access to the Internet. The lab has a proxy server for http and https traffic.

In Ubuntu does the router assign your computer an IP address? If you open a terminal and type ifconfig you should see something like: eth0 Link encap:Ethernet HWaddr 01:02:03:04:05:06 inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::42:5dff:fe30:2342/64 Scope:Link inet6 addr: ...

You've installed the wrong driver! These modules do not get associated with your wireless card and are therefore not loaded. Where did you get from that this is the correct driver? I guess that there aren't drivers which work with 14.10 and the underlying kernel (yet)... I can't find anything about it on Google.

Can you please let's know whether this is a Laptop or PC, if this is a laptop - then the Network driver might not configured or installed. We can solve this issue by installing the proper network driver.

Not sure what might have happened to your system, but you may be interested in setting those in your terminal/commandline: export http_proxy="http://user:password@proxy_server:port" export https_proxy="https://user:password@proxy_server:port" Can you actually check what shows: echo $http_proxy (btw - you may use this way for ftp_proxy, too)

So after messing around I figured out how to fix my issue, sudo gedit /etc/rc.local after I went there I put ethtool -s eth0 autoneg off speed 100 duplex full above the exit 0 and this seemed to fix it at least for now. I would like to thank Fabby for all the help, I didn't try his answer, but I may have to if I get the problem again.

Found a fix here: In my testing, using the Avahi preferred solution of changing the mDNS domain to something else, I did indeed regain the ability to resolve .local hosts from my VPN, but I effectively lost use of all mDNS devices because (I presume) they weren't also changed to advertise in that same replacement local zone. With no idea how (or the ...

I believe the driver you've installed is incorrect for your 14e4:4727 device. Please get a temporary wired ethernet connection, open a terminal and do: sudo -i apt-get remove --purge bcmwl-kernel-source apt-get update apt-get install firmware-b43-installer echo brcmsmac >> /etc/modules exit Reboot and your wireless should be operating correctly.

I do not believe your graphics card driver is at fault. It sounds more like your having a problem with your Huawei router configuration.

You can also see this link for more information ...

Ok, I tried a lot of things since I originally posted this but nothing worked. And then i realized that sometimes, not fixing it can also be a solution. A solution that works for everyone owning a smartphone is to connect the phone to the local network and use USB tehthering. Works regardless of OS. I know it's stupid. But it just works.

try using a public DNS , because not accessing a site is due to not finding its ip address or not finding the server, so not accessing SOME sites means you can access others , so you internet access is good except that you are not resolving some names, try using 8.8.8.8 , 8.8.4.4

I have two ideas of which I recommend you plan on trying both. My first thought was that you should prepare another USB install thumbdrive, this time using 12.04, and I suggest that only because there seem to be a lot of complaints about 14.04. My second thought may be better though. I suggest you make a second install thumbdrive, but this time the same ...
