can't ping

[Mike Wright]

Hi everybody,

I have no idea how I got in this mess, but I've lost the ability to use 
ping as a regular user.  sudo still works.

Nothing in lsattr, regular perms are 755 no suid.

ping: socktype: SOCK_RAW
ping: socket: Operation not permitted
ping: => missing cap_net_raw+p capability or setuid?

Any help?  Especially ideas on how I managed to do this?

Thanks
