[AusNOG] Telstra mobile down "nationwide"

[James Gray]

In addition to the traditional swiss-army knife known as "telnet", getting
"curl" to dump just the HTTP headers is also a handy one to keep up your
sleeve:

0:>*curl -I http://triplezero.com.au <http://triplezero.com.au>*
HTTP/1.1 200 OK
Connection: close
Date: Tue, 09 Feb 2016 04:45:18 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
Content-Type: text/html; charset=UTF-8

Also telnet wont work with SSL sites (ie, https), but if you have openssl
installed, you can do this instead:

0:>*openssl s_client -quiet -connect www.google.com:443
<http://www.google.com:443>*

The openssl method also works on other SSL-enabled service like POP3S and
IMAPS etc. I have it aliased in my shell config:
*alias stelnet="openssl s_client -quiet -connect"*

...then all I need to do is: "stelnet host:port"

Just good to have tucked away in case you need to break out the
command-line hammer.

Cheers,

James
