I would like to know how I can identify this problem. I have been surfing on Internet today without any problem and not setting changed. I really think this is the cause of HTTP packet from internet to Chrome. So, Someone seems be cracking/replace my session.

Of course, I checked 3rd party personal firewall but not Mac one because I did not touch anything since it's rebuilt.

My environment:

  • OSX Mavericks
  • Chrome(No proxy setting)
  • Safari(No proxy setting)
  • Wired LAN

All are latest patch applied but not yesterday happened.


  • Ping
  • telnet 80
  • traceroute
  • nslookup
  • Ping
  • telnet 443
  • traceroute
  • nslookup
  • personal Symantec application firewall is reseted as default
  • chrome://net-internals/#dns (@T Goi suggested me in comment area)

These works fine which means my network interface, DNS, network, web server is up.


Check to browse

  • Chrome failed(This webpage is not available.
  • Safari Success.

Check to browse no existed domain(which is middle one):

  • Chrome failed(of course, Unable to connect to Internet).
  • Safari failed(of course, Safari can't find the server).

Browsing chrome and safari

Based on that I have a several question in below.

  1. What will be a cause?
  2. How to identify/check the issue.
  3. Could you provide me the log of HTTP request/respond packet using Wireshark to compare in my end? (you are not necessary to pick up the log, I will handle it)
  4. When I use major 3rd parties firewall software such Symantec, How Mac one will appeared in security and privacy setting? Is it turned on like below picture? security and privacy setting

May be I will have to use packet capture? I'm not familiar with the browsing packet. So if you could advice me, That would be helpful for me.
