Internet not working in Couldera VM

[#1]

Since yesterday afternoon, i am not able to access internet in cloudera (Oracle VM ). I keep getting errors

Cloudera: Firefox can't establish a connection to the server at localhost:8889

Two days ago things were working fine. and I don't think it is an internet problem on my end since i have been using it all day.

Any idea? Thanks

Hello @bsaad 

1. Could you check whether you are able to connect to internet from the Oracle VM, using a ping test to google.com

2. Could you cross-check the port number 8889 is up and listening by using the following command as the root user

#netstat -ntpla | grep 8889

Thanks for your reply.

1: the google test was successful.

2: the command you suggested did not give me any response. which which directory do i need to run it?
