ping 192.168.5.6

as well as

/sbin/ping 192.168.5.6

traceroute gives me a similar responese:
/usr/sbin/traceroute 192.168.5.6
traceroute to 192.168.5.6 (192.168.5.6), 64 hops max, 40 byte packets
traceroute: sendto: Invalid argument
 1 traceroute: wrote 192.168.5.6 40 chars, ret=-1
 *traceroute: sendto: Invalid argument
traceroute: wrote 192.168.5.6 40 chars, ret=-1
 *traceroute: sendto: Invalid argument
traceroute: wrote 192.168.5.6 40 chars, ret=-1
