Start by querying the network adapter to see how the connection is setup: ifconfig -a make sure you have a DNS server specified, as an IP address, and that the adapter is using DHCP to get this information. If no DNS server is specified (field is blank), then you are not getting an appropriate answer from your DHCP server at college, and should contact ...

Are your drivers for the network cards loading? A quick check might be to mouse over your network notification area or try to manually connect to a network (I'm not terribly familiar with KDE). Running lspci -vv might net you some information about the cards and what driver they are using , if they are using one.

Since asking this question 30 minutes ago, I played around a found a solution that happens to work for my configuration, so decided I should share it in case other's might need something similar. (It's not a fully general solution, though, so hopefully someone can come along and give a solution that's more robust.) Instead of disabling OpenVPN on my laptop ...

I use system-load-indicator by Michael Hoffmann. It shows everything (CPU, net, disk...) but you can selectively turn on what goes into the indicator panel. Have a look at that.

You will need more than one component to do this, and be aware that there are many ways to accomplish this; At first you will need to have an Linux Domain Controller (Like Windows AD), to do your AAA. Then also an database server must be used to store these information (LDAP in most cases). There are "all-in-one" solutions for this like Fedora 389DS. And ...

There are several software solutions designed especially for those task, but I can suggest a simple ad-hoc solution: On server, create a single grand /home directory and share it by NFS. On each client, move following files so that they, too, reside in NFS and share between PCs. /etc/passwd - user account information less the encrypted passwords ...

There are 2 ports: a source port (browser) and a destination port (server). The browser asks the OS for an available source port (let's say it receives 33123) then makes a socket connection to the destination port (usually 80/HTTP, 443/HTTPS). When the the web server receives the answer, it sends a response that has 80 as source port and 33123 as ...

Your problem is that you want to use the SMTP service on your local computer and this service does not exist! So, ou need to install the SMTP daemon apt-get install opensmtpd then, you need to start it using sudo smtpd and now, your command should work.

Google probably works because you have it set to use ssl (https:// instead of http://) which means it is using port 443 and the packets are encrypted so they cannot use packet examinations on select ports to determine if you are tethering. Some mobile providers, including at least metroPCS and T-Mobile, use this IPE to block tethering both over wifi and USB ...

I think, there is a way to directly attach a physical network card to a kvm/qemu, but I am of no help with this. IMHO, there is a way to attach any or almost any physical pci and usb device to the kvm/qemu vm.

Are you sure the name is eth0? Try ifconfig eth1 up or eth2 up etc. If your ethernet card is properly working then it should be identified at this time. If identified you can go and edit network interfaces by sudo nano /etc/networ/interfaces. Then do a network restart by sudo /etc/init.d/networking restart or you can reboot.

By default eth0 doesn't start sometimes. Therefore try /etc/init.d/networking restart Then ifconfig -a Also check your /etc/network/interfaces file and verify the eth0 interface if exists. Hope this helps. Let me know.

So what I found was some behavior I think is not supported by the Linux clients. I loaded a Windows 7 VM and the stock Cisco VPN client. When I ran it from Windows, I was prompted for all the usual but afterwards there was an additional prompt for "The Next" RSA key after the one that I had used. So what I think happened is that this behavior was triggered ...

I have a Dell Inspiron 17, and I had the same problem. It is due to the fact that the machine uses a wifi card that requires a proprietary driver. It is easy to fix.

The proprietary driver wl is generally not the preferred driver for your 14e4:4727 device. Let's remove it: sudo apt-get purge bcmwl-kernel-source And now we load the preferred driver: sudo modprobe brcmsmac It may take a reboot. Is there any improvement?

First, let's be certain that the correct driver wl isn't blacklisted: gksudo gedit /etc/modprobe.d/blacklist.conf Use nano or kate or leafpad if you don't have the text editor gedit.

is there any reason why you are running the iptables firewall and fail2ban inside your internal network, from behind a hardware firewall? In my experience they are quite tricky to setup and diagnose. especially when you are running fail2ban, whose explicit purpose is to actually make what you are trying to do difficult. e.g. If you try to unsuccessfully try ...

Ok, so mainly you will want to do two things: add a prompt when you start your desktop session, asking for your password, and make a prompt each time the interface is brought up again. So, you will need to use an Upstart session job to guarantee you that an X session is started and the DISPLAY variable is set. Session jobs go in ~/.config/upstart/, not ...

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 ...

The linux kernel uses "generic drivers" for your computer. Where as Windows requires explicit installation of your drivers. Hence some of the functionality that you get in windows might not be available in ubuntu. You can go to the website of your NIC card vendor and check for drivers that can be installed in ubuntu. Reinstall the driver. All will be fixed. ...

If you can use DHCP, do it and delete all DNS settings from the interface, let router assign you the right DNS server to your network card, if you do your settings manually in /etc/network/interfaces or else, you may configure multiple settings for one interface, wlan0 and wlan0:0, one for school and one for other, there use only the necessary DNS servers in ...
