Security focus (aka bugtraq) reachability

  • From: Mike Tancsa
  • Date: Fri Sep 13 16:08:32 2002



Can anyone with a host in the IP range of 64.0.0.0/8 confirm if they can connect to the www.securityfocus.com or mail.securityfocus.com ? (i.e. the bugtraq people). I have tried from two separate networks (mine and a totally separate ISP nothing to do with my AS) and both cannot connect from different IP addresses in the 64.0.0.0/8 range. From IP addresses outside of 64/8 its fine. Its as if they dont have ip classless enabled or some rogue firewall rules / routes.

e.g.
quartz# telnet -s 199.212.134.17 www.securityfocus.com 80
Trying 66.38.151.10...
Connected to www.securityfocus.com.
Escape character is '^]'.
^]
telnet> close
Connection closed.
quartz# telnet -s 64.7.128.97 www.securityfocus.com 80
Trying 66.38.151.10...
telnet: connect to address 66.38.151.10: Operation timed out
telnet: Unable to connect to remote host
