Useful Links – Technical Resources

Intro
From time-to-time I come across sites that really help out, and ones that true, might be found quickly in a Google search, but some offer capabilities you may not have even realized existed.

The links
So without further ado, here they are. They need some organizing yet!

– Geographic location finder for any IP address. There are zillions of them out there. Some are overly aggressive with advertizing so be wary. Here’s a really good one that shows your IP and perceived location without the ads: https://www.vpnmentor.com/tools/ipinfo/

Networking
Check your speed by downloading one of the large files from ftp://speedtest.tele2.net/ such as ftp://speedtest.tele2.net/50MB.zip .

Reputation links
– Reputation information for any mail server. Just plug in the IP. Will also show what blacklists the server is on and the reputation of others servers on that segment. I think it’s run by Cisco. http://www.senderbase.org/
– Reputation of any URL, sponsored by Bluecoat, makers of the free edition K9 Webfilter. http://sitereview.bluecoat.com/sitereview.jsp

Webmaster links
archive.org will show what your site looked like in the past, sometimes even years in the past.
www.alexa.com, to see how unpopular your web site is
– Say you see a photo on a web site and you want to know if it was used elsewhere, or if the site cropped it

– Open source information and knowledgeable discussion. http://www.softpanorama.org/

Security
– Good discussion of ongoing security matters, though too heavily weighted on Social networking. Articles daily with interesting reader comments. http://nakedsecurity.sophos.com/
– Web site malware checker. http://sitecheck.sucuri.net/scanner/. I’ve used it once. I guess it’s OK, but probably not nearly as thorough as commercial products. I guess it doesn’t look for vulnerabilities, just malware.
urlquery.net, a service for analyzing and detecting web-based malware

IT
– most under-appreciated blog by an IT professional, networking concentration. http://drjohnstechtalk.com/blog/ Hey, I can toot my own horn!
– Screen-sharing application join.me
– Ookla’s Down Detector gives the status of hundreds of major web sites. https://downdetector.com/

Home User
– Best broadband speed test. https://fast.com/ It’s simple, but doesn’t shower you with aggressive ads.

– speedtest also looks good. https://speedtest.net/

Prevent your neighbor’s WiFi SSIDs from being offered to you: https://www.howtogeek.com/331816/how-to-block-your-neighbors-wi-fi-network-from-appearing-on-windows/

– Permanent HTTP site – will never be https: http://neverssl.com/. It can be hard to find a site that doesn’t run SSL these days so this can be useful, e.g., when you want to sign on to guest Wifi such as hotels offer.

Find an Android phone: http://google.com/android/find

Computer and Linux Hobbyist
– Cheapest low-power Linux computer. http://www.raspberrypi.org/. At about $35 this looks really interesting for the hobbyist.

Towards a Responsible and Ethical Internet
– a search engine that doesn’t track! I just heard about this on Marketplace. Unfortunately it’s not as sophisticated as Google with type-aheads. I checked a few searches that should bring up some of my blog posts and – they did – so it must have some reach into obscure web sites duckduckgo.com

And another I’ve just learned about: https://www.startpage.com/
