I have installed Kubuntu. I am able to connect to Internet and able to access external sites, but in my local network I have bugzila installed that I am not able to access, even I am not able to ping the gateway also
Below is the result of ifconfig command:

~# ifconfig
eth0      Link encap:Ethernet  HWaddr b8:70:f4:da:f9:a8

How can I resolve this?

Which interface is connected to the internet? "eth0" or "wlan0"? Did you add "gateway" IP to both interfaces? If so, remove gateway IP from the local interface.

  • Thanks for reply Hasan , wlan0 is connected to the internet , i had added the gateway for eth0, which i have removed now as you suggested , but still i am not able to access any machine in the local network .

  • @Roopesh Since you've solved your problem, and apparently done so in a way not suggested by the existing answer, you should answer your own question with the solution, so it's clear to people searching with similar problems how you fixed this.

You have two equal networks with address: on two network interfaces: eth0 and wlan0. And it seems a gateway you are using configured toward the Internet but have no connection with your local network.

  • You need to configure your wi-fi router for different network address: or something else.

  • Check your routes table by command: ip route

  • You could see similar record:
    default via dev wlx8c882b131d84 proto dhcp metric 600

  • local network with Bugzilla should be accessible from now because of there are no conflicting networks present anymore.
