Yeah, even on Debian systems where ping isn't setuid root, it still seems
to need special capabilities that strace interferes with, or isn't
allowed to attach to, or something.
unicorn:~$ strace -o log ping www.debian.com -c 4
ping: socktype: SOCK_RAW
ping: socket: Operation not permitted
ping: => missing cap_net_raw+p capability or setuid?
So, pick something other than ping, or run the strace as root.
