Hello, i've spent hours looking over this but unable to find a solution. I am unable to get my virtual machines proper network coectivity. My setup is a headless ubuntu 16.04 server with virtualbox 5.1.2 with bridge networking setup.the headless server coects and pulls a DHCP address fine and can talk to everything, but the VM's caot whether DHCP or manual network config.here is my network config for the headless server# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).source /etc/network/interfaces.d/*# The loopback network interfaceauto loiface lo inet loopback# The primary network interface#auto enp2s0#i...

Hello, I'm having trouble getting ubuntu 16.04 server to request/get a dhcpv6 provided IP address when the networking.service restarts or the server reboots. I'm able to manually run dhclient -6 and get a dhcpv6 provided IP address. Under normal operation I just get a autoconfigured/peer probed IP address that is based on the subet and mac of the server. This is my network configuration. Code: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto ens6 iface ens6 inet dhcp iface ens6 inet6 dhcp I've attempted to change any system setting with ipv6 and autoconf in it to 0 but that doesn't seem to change how this system attempts to get an ipv6 ...

Hi,About 10 minutes ago I lost my network coection temporarily, something which occasionally happens for whatever reason.However, this time I noticed that whatever URL I entered in Firefox, it "redirected" (not sure if that is the word) to 192.168.1.1, the router IP address - as in the browser URL window showed http://192.168.1.1. It didn't take me to the router's config page or anything like that, it just hung waiting for a response.Any idea why this happened and is it a cause for conce?On rebooting my Ubuntu system (not the router) the problem went away, but not sure if this is due to the reboot or due to a temporary network error which then went away.This is with 12.04 LTS and Firefox 47....

I stretched etheet cables to both ends of my house, in order to create a wired LAN instead of relying on wifi signals. I then attempted to edit /etc/network/interfaces to reflect:auto loiface lo inet loopbackiface eth0 inet staticaddress 192.168.2.11netmask 255.255.255.0gateway 192.168.1.251 auto eth0Can anyone assist? I'm not sure what the issue is. It worked at first, with the etheet cable plugged in, and ordered the wifi stopped. But upon shutting down the computers, I can't coect to the etheet..FYI, I"m ruing 16.04 Ubuntu LTS on a laptop, and Kubuntu 16.04 LTS on a PC tower. Let's block ads! بخوانید...

AFAIK it is the IP(s) of the machine's own interface(s) (whether received from a router, or configured statically)The defaults are 0.0.0.0 for IPv4 or :: for IPv6, representing "any interface"AFAIK setting it to a specific (restrictive) IP only has value when your machine has multiple interfaces / multiple IP addresses configured (for example, if the machine itself is a gateway, you could allow SSH via the LAN-facing interface, but not from the WAN)What exactly are you trying to achieve? If you want to blacklist / whitelist IPs for SSH you can do that via firewall rules (either using iptables or via ufw) Let's block ads! بخوانید...
