What's wrong? Ping: icmp open socket: Operation not permitted
Hello everybody,
I've been installing and configuring 12.04. It was working fine, but after some reboots I started to see some problems with the network.
First, when the computer started up, it was displaying (something like) this message:
Waiting for networking configuration
And then,
waiting 60 seconds
Finally
No full network configuration
So searching the web I found out it had to do with the configuration at /etc/network/interfaces. So I partially emptied the file (removed my eth0 configuration) and tried to create the network configuration directly with nm-connection-editor.
Surfing the web works, but when I want to ping with a regular user (to any address), I get
Code:
Ping: icmp open socket: Operation not permitted
It's funny though, because if I add sudo, the ping operation executes normally.
I tried going back and re-adding the /etc/network/interfaces configuration, but it's the same.
Now I don't know what I should do, or what is the cause of the problem.
Any help will be greatly appreciated.
The Truth shall set you free
