If you have questions about a Linux guest (see topic title), please post them in the "Linux Guests" forum, not some random other forum such as "Windows Hosts".

Moving this one.

Thanks Mpack, but I think it is more to do with windows 10 and Virtualbox, I am sure it has nothing to Linux in my case

In that case it might be better if the topic title referenced your actual problem, and didn't only refer to the guest OS.

Btw, I am not ignoring your question, but I don't use Linux and I'm not a network expert. Linux networking experts should be more easily found in this new forum.

Can you ping 8.8.8.8 from the guest? If so then it indicates a DNS issue or something blocking access.

Yes it does work

Code: Select all

[oracle@ol7-121-rac3 ~]$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=48 time=16.8 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=48 time=18.6 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=48 time=19.0 ms
64 bytes from 8.8.8.8: icmp_seq=4 ttl=48 time=20.7 ms
64 bytes from 8.8.8.8: icmp_seq=5 ttl=48 time=23.9 ms
64 bytes from 8.8.8.8: icmp_seq=6 ttl=48 time=16.1 ms
64 bytes from 8.8.8.8: icmp_seq=7 ttl=48 time=16.3 ms

So it is DNS that is failing so open the guests terminal and type the following and post the results here:

Code: Select all

cat /etc/resolv.conf

Hi Perry, you are a life saver, I made changes to resolv.conf which messed up, i just commented the line and everything started working again, thank you so much. I was struggling since last 12 hours

Code: Select all

[root@ol7-121-rac3 ~]# cat /etc/resolv.conf
