I can't ping my IP address or connect via SSH.
After a reboot, I am unable to connect to my Linode via SSH. I also cannot ping my IP address.
It sounds like you might be having issues with your firewall.
I would run the following command to take a look at the ruleset that is currently active for iptables. If you are unable to connect via SSH, you can use our Lish console to connect.
If you find that your firewall rules are blocking your connectivity, you can run the following set of commands to flush iptables:
sudo iptables -P INPUT ACCEPT sudo iptables -P FORWARD ACCEPT sudo iptables -P OUTPUT ACCEPT sudo iptables -t mangle -X sudo iptables -t mangle -F sudo iptables -t nat -X sudo iptables -t nat -F sudo iptables -X sudo iptables -F
After that process is complete, you can check on the status of your SSH service and restart that if necessary.
sudo service ssh status sudo service ssh restart
That should get you moving in the right direction.
