Another check...
« on: July 03, 2013, 08:53:11 PM »
Some more tests:
Handy for each sys admin....

Dns lookup for a given HostName, e.g. we-in-f102.1e100.net  -> http://www.dnsqueries.com/en/dns_lookup.php
Results for the example hostname:
TTL         Class    Type    Details    
86400  IN          A          173.194.66.102

Line Quality - Ping Test, go here: http://www.dslreports.com/pingtest
WINDOWS VISTA USERS and UP: Vista TCP tuning (tweaking) is NOT advisable. The Vista TCP stack does a reasonable job of tuning the receive window dynamically, there are no known registry tweaks that would optimize Vista better than its default configuration.
Tweak Test - to test if your computer is setup correctly for broadband TCP connectivity; http://www.dslreports.com/tweaks  XP
to be combined with this test based on results/advice of the Tweak Test: http://www.dslreports.com/drtcp  (doctor tcp)       XP

enjoy,

Hi wyrmrider,

Do this debug resolver test first: http://netalyzr.icsi.berkeley.edu/index.html  (the best from berkley education - great evaluation tool for your connectivity)
and we could go over the results

You could also later work this tool: DNS Bench exe downloadable from here: https://www.grc.com/files/DNSBench.exe
Instructions there from Steve Gibson, nifty little tool (a mere 163 kByte) and you can have a decided clue what is going on under the DNS hood,

Hi wyrmrider,

Do that, a little pulse taking now and again and a health check
is advisable to know what is going on.
A lot of people criticised good old Steve Gibson,
but he developed some line of mighty fine nifty little check tools,
and this one will benchmark and improve the settings.
I have it to run from time to time.
Takes some time to go through this and thoroughly test with it,
I give you t will be worth waiting for the final results
(takes some half hour or so).
Good we can do these exercises here at the forums,
it is inspiring...

regards,

polonus

fyi
Minor Aberrations –

    Certain TCP protocols are blocked in outbound traffic
    Fragmented UDP traffic is blocked
    We detected at least one proxy
    Network packet buffering may be excessive
    Not all DNS types were correctly processed
    Some sites were blocked using DNS (comment most likely Hosts)

These abberations are not  really issues and for the greater part could be firewall induced,
