Amazon EC2 instance missing Network Interface
- by Sergiks
I am running Linux on a t1.micro instance at Amazon EC2.
Once I noticed bruteforce ssh login attemtps from a certain IP, after litle Googling I issued the two following commands (other ip):
iptables -A INPUT -s 202.54.20.22 -j DROP
iptables -A OUTPUT -d 202.54.20.22 -j DROP
Either this, or maybe some other actions like yum upgrade perhaps, caused the follwing fiasco: after rebooting the server, it came up without the Network Interface!
I only can connect to it through AWS Management Console JAVA ssh client - via local 10.x.x.x address.
Console's Attach Network Interface as well as Detach.. are greyed out for this instance.
Network Interfaces item at the left does not offer any Subnets to choose from, to create a new N.I.
Please advice, how can I recreate a Network Interface for the instance?
Upd. The instance is not accessible from outside: cannot be pinged, SSH'ed or connected by HTTP on port 80.
Here's the ifconfig output:

What is also unusual: a new micro instance I created from scratch, with no relation to the troubled one, was not pingable too.
