First, the loopback interface is required and must not be removed. I suggest you amend the /etc/network/interfaces file to this: auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.4.20 netmask 255.255.255.0 gateway 192.168.4.1 dns-nameservers 8.8.8.8 4.2.2.2 Get the system to re-read and ...

Your device uses the driver rtl8192cu. The built-in driver is known to be unstable and tricky to connect. With a working internet connection,please do: sudo apt-get install linux-headers-generic build-essential dkms git clone https://github.com/pvaret/rtl8192cu-fixes.git sudo dkms add ./rtl8192cu-fixes sudo dkms install 8192cu/1.10 sudo depmod -a sudo cp ...

Please see: Installing Broadcom Wireless Drivers The correct driver for your device 14e4:432b is bcmwl-kernel-source: sudo apt-get install bcmwl-kernel-source Reboot.

If it does connect, nmap can perform a scan. sudo nmap -PN 169.154.0.0/16 Also, more obscurely, if the device has a serial port you may get it to spill its guts on boot, and this might reveal static ip details as well. Granted, this requires a cable, and guessing or obtaining the protocol attributes.

Install the package firmware-b43-installer: sudo apt-get install firmware-b43-installer You will need to enable the multiverse repository to be able to do this. If you chose to install 3rd party software when installing Ubuntu, then it should already be enabled. If not, see this question. You may need to restart your computer afterwards for the card to ...

You can install a driver by running sudo apt-get install git build-essential git clone https://github.com/lwfinger/rtlwifi_new.git cd rtlwifi_new make sudo make install But you need to be connected by wire for that. Default dirver does not work well. You can install Ubuntu without network connection and install the driver later. The only problem is ...

You need to distinguish between 3 things: Predictable interfaces names biosdevname 70-persistent.rules udev rule You either choose to use one of these solution but you don't use 2 or 3 at the same time. (In fact, you can but one will take precedence and mask the other(s)) A good introduction to the current situation is the post on the ubuntu dev mailing ...

Here are a few ways: grep. There are various regular expressions that will pick these up. Here, I am looking for 5 repetitions of 2 letters or numbers followed by a colon, then any two characters. The -i makes the match case insensitive and the -o makes grep print only the matched portion. -E enables extended regular expressions. The same regex also works ...

You can access the address file for each device on the /sys virtual filesystem. The MAC address should be in /sys/class/net/<device-name>/address: $ cat /sys/class/net/enp1s0/address 34:17:eb:5d:88:7c For all devices: $ cat /sys/class/net/*/address 34:17:eb:5d:88:7c 00:00:00:00:00:00 64:5a:04:69:50:45

xxx.xxx.xxx.xx4:25565 Based on what you said I am sure that you haven't used this xxx.xxx.xxx.xx4 specific IP in the server start process or server configuration.

The easiest way would be to use grep with PCRE: $ ifconfig -a | grep -Po 'HWaddr \K.*$' 74:d4:35:84:34:13 grep -P will enable us to use perl compatible Regex grep -o will only take the matched portion of the line We have matched HWaddr before our desired match (MAC addresses) and then discard HWaddr by \K to print only the MAC addresses. @Helio has ...

ifconfig -a | grep HWaddr | awk '{print $5}' If your system output is non-English in this command, then it makes sense to run it this way. LANG=C ifconfig -a | grep HWaddr | awk '{print $5}' This is applicable to all solutions.

It is possible that resolvconf is misconfigured. This is especially likely if you have been playing around with its configuration files without really understanding how resolvconf and NetworkManager work.

Ok, this is weird...I tried another LAN wire this morning and it worked, despite already trying 2 others yesterday that also worked when connected to other machines.

The usual way to get a server to connect is in the file /etc/network/interfaces. Check yours: cat /etc/network/interfaces Is an ethernet interface declared, typically like: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp Is the ethernet interface actually eth0, or is it eth1, eth2, p3p1, ...

Following command helps a lot: sudo service winbind stop Somehow (I do not know exactly how) my samba server is missconfigured to talk to winbind even if it has a standalone server role. This seams to cause a misscommunication with winbind and NT_STATUS_NO_MEMORY failure on first login. Have fun ppl!

The reason why you can't see your NAS, its broadcast can't reach your virtual machine when using NAT. Think as your virtual machine is behind a router. The best is what Mr.Gosh recommends (bridged networking). Another option is to enter your NAS IP directly from the virtual machine (If you know its IP or it's static)

After some research, I've found the root cause. As reported here: https://bugs.archlinux.org/task/44315, the issue is due to the combination of the new linux kernel version with the Qualcomm ethernet driver The following combination IS NOT WORKING Linux kernel 3.19.0-18 (Ubuntu 15.04) Ethernet driver alx 0000:04:00.0 eth0: Qualcomm Atheros AR816x/AR817x ...

You can solve it by re-installing the driver and running sudo update-initramfs -u after that.

Network Manager uses dynamically your /etc/resolv.conf with dnsmasq. Each connection can have our dns server listed. If you wish to avoid this behavior you can do this In /etc/NetworkManager/NetworkManager.conf comment out the dns=dnsmasq sudo nano /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile,ofono #dns=dnsmasq ...

Switch to "bridged networking" - than you'll get an IP of your LAN subnet in your virtual machine and therefore can connect to your NAS.

NetworkManager is the program which (via the resolvconf utility) inserts address 127.0.1.1 into resolv.conf. NM inserts that address if an only if it is configured to start an instance of the dnsmasq program to serve as a local forwarding nameserver. That dnsmasq instance listens for queries at address 127.0.1.1. If you do not want to use a local forwarding ...

I see that you have a wired connection. Then install the driver this way. But close all programs before that. Like Synaptic or others. Or just reboot. Some program is blocking installation. Run in terminal sudo apt-get install bcmwl-kernel-source sudo modprobe -r b43 bcma sudo modprobe wl Wi-Fi should work.

You can add script in /etc/network/if-up.d/ and when wlan0 go up call script witch will do sudo mount -a. Make script called script with execute permissions 755 sudo nano /etc/network/if-up.d/script # Check for specific interface if desired [ "$IFACE" != "wlan0" ] || exit 0 # Do something sudo mount -a

The first thing to do is do enable IP forwarding. This is done either by using echo "1" > /proc/sys/net/ipv4/ip_forward Then, we will add a rule telling to forward the traffic iptables -A FORWARD -i eth0 -o usb0 -j ACCEPT iptables -A FORWARD -i usb0 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT and finally, we ask IPtables to masquerade ...

If this problem persists in Windows, it is not an Ubuntu problem. It is either a hardware problem, or a problem with your wireless environment, or just low signal strength. Try to get closer to your router. And also changing a channel in your router settings may solve that problem, if there are too many wireless networks using that channel in your ...

You have several possibility to change the default route. Nice place for this kind of action is in /etc/network/if-down.d/ or /etc/network/if-up.d/ You can in this folder put some script and make action. For example put this script in /etc/ppp/if-up.d/ to make default route to ppp0 interface every time when go up, make script called script with execute ...

This is most likely a configuration problem on the server side. The vpn server should only push domains that he can resolve. For example if you use an openvpn server a user configuration might look like this: ifconfig-push 172.16.0.51 255.255.255.0 push "route 172.16.1.0 255.255.255.0 172.16.0.1" push "route 192.168.2.0 255.255.255.0 172.16.0.6" push ...
