I have no trouble running it, but it does not respond:

$ ping 172.16.4.52
PING 172.16.4.52 (172.16.4.52) 56(84) bytes of data.

--- 172.16.4.52 ping statistics ---
11 packets transmitted, 0 received, 100% packet loss, time 10009ms

You're ping is working but your network is not or firewall prevents
ICMP traffic or an invalid ip address

$ traceroute 172.16.4.52 # to find the bottleneck

verify DNS servers and MTU size

$ ifconfig $ route


Hi all,


A ping to 172.16.4.52 can only work if this ip-address is inside your own network-segments.

10.abc.def.ghi
172.16.jkl.mno
192.168.pqr.stu

are ranges that are private, so cannot be used for internet ip-addresses.

If not defined at 'your' LAN they cannot be reached by ping, traceroute or whatever.

The first issue of ping no such process if complete different issue.


Kind regards,
