I find a strange phenomenon in my corporate network:
I can execute
curl google.com command successfully:
[root@localhost ~]# curl google.com <HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8"> <TITLE>301 Moved</TITLE></HEAD><BODY> <H1>301 Moved</H1> The document has moved <A HREF="http://www.google.com/">here</A>. </BODY></HTML>
ping google.com failed:
[root@localhost ~]# ping google.com PING google.com (126.96.36.199) 56(84) bytes of data. ^C --- google.com ping statistics --- 1569 packets transmitted, 0 received, 100% packet loss, time 1568463ms
I suspect the sysadmin has done something, but not sure. Could anyone give some clues how to debug this issue? For example, does the sysadmin set some rules which can filter
ping command? How can I verify it?
