But if you transform the rule in question a little, like this:
iptables -I OUTPUT -p icmp --icmp-type echo-request \
-j REJECT --reject-with icmp-admin-prohibited
ping will respond with 'Operation not permitted'. An exact wording of the
message seems to depend on actual ping implementation.
So, checking firewall rules is a valid advice. It's just this particular
problem happens due to lack of file capabilities.
