Re: extension for Firefox to force HTTPS always?

[Harry Hoffman <hhoffman () ip-solutions net>]

what is wrong with his suggestion?

If you look at the situation the following things happen:

[hhoffman@localhost ~]$ host www.cnn.com
www.cnn.com has address 64.236.16.20
www.cnn.com has address 64.236.16.52
www.cnn.com has address 64.236.24.12
www.cnn.com has address 64.236.29.120
www.cnn.com has address 64.236.91.21
www.cnn.com has address 64.236.91.22
www.cnn.com has address 64.236.91.23
www.cnn.com has address 64.236.91.24
Host www.cnn.com not found: 3(NXDOMAIN)


[hhoffman@localhost ~]$ openssl s_client -connect www.cnn.com:443


[root@localhost ~]# tcpdump -i wlan0 -ln tcp port 443 and net '64.236'

If there are a ton of addresses associated with the hostname record 
you'd be sitting there for a long time, no?

It'd be nice if sites sent a unreachable message but some ppl still 
believe that blocking all ICMP is ok...

go figure.
