[NL] @xs4all – inkomende telefoontjes blokkeren: Fritz!Box of VOIP-selfcare

Posted by jpluimers on 2016/01/18

xs4all biedt twee mogelijkheden om inkomende telefoontjes te blokkeren: via de Fritz!Box of via VOIP-selfcare.

Als je in het VOIP-selfcare een nummer toevoegt onder “Inkomende oproepen blokkeren”, dan krijgt de beller een “bandje” dat het een ongewenst gesprek is. Dat wilde ik niet: net als bij inlog fouten wil je zo weinig mogelijk informatie geven over een oorzaak.

Als je oproepen van een specifiek telefoonnummer via de Fritz!Box blokkeert, dan krijgt de beller meteen xs4all voicemail. Ook niet wat ik wilde, maar het zette me wel op het juiste spoor.

De voicemail komt doordat de Fritz!Box dan een meteen een in-gesprek (line busy) genereert en zo het telefoongesprek afwimpelt. Omdat voicemail bij xs4all standaard aan staat, gaat het gesprek dan meteen naar voicemail.

In dit geval wilde ik toch van de xs4all voicemail af, dus heb ik dat gedaan door in de VOIP-self care alle vinkjes bij “Gesprekken doorschakelen” uit te zetten, zie het plaatje onderaan.

Een “Gesprekken doorschakelen” zonder vinkjes heft alle doorschakelingen op, waardoor de beller precies het antwoord krijgt dat de Fritz!Box voorschotelt.

Threading in C# – Free E-book

Posted by jpluimers on 2016/01/18

Still a great book. I love the chapter Threading in C# – Free E-book which you also can get as a PDF download.

It’s a chapter from C# 56/5/… in a Nutshell by Joseph Albahari. Great book!

Don’t forget to read these as well: Jon Skeet: Multi-threading in .NET: Introduction and suggestions (printable) Multi-threading in .NET: Introduction and suggestions (browseable)

Nostalgie: KPN zet inbelplatform uit en laat Xs4all inbelverkeer afhandelen – IT Pro – Nieuws – Tweakers

Posted by jpluimers on 2016/01/17

This Dutch caught my eye: “Dutch telecom operator KPN has turned off the inbound internet dial-up equipment. It keeps possible to dial the number, as dial-up traffic is now handled by provider xs4all”:

KPN heeft de apparatuur van zijn inbelplatform voor internet uitgezet. Het blijft nog wel mogelijk om in te bellen via het nummer 06760-12321, maar het inbelverkeer wordt voortaan afgehandeld door provider Xs4all.

Source: KPN zet inbelplatform uit en laat Xs4all inbelverkeer afhandelen – IT Pro – Nieuws – Tweakers

The thread is full of nostalgia on Dial-up Internet access, like:

I still have my original Courier HST Dual Standard modem from USRobotics I got around 1987. It’s looks like the second from the bottom at (image via: Do Modems Still Matter?) the picture below (one day I will make a picture when I’ve cleaned out the glass cabinet it is in; there are some more USRobotics, ZyXEL and DrayTek modems in it too).

There is a very interesting piece of USRobotics (in Russian, but Google Translate does a nice job on it): The history of the US Robotics.

I wrote mentioned the Courier HST Dual Standard before in Going to try PowerLine (next to CAT5, and having used 10Base2, 10Base-T, 100Base-TX and 1000Base-T), but never about the why, so here it is:

The Courier HST standard would train faster and at better speeds over Intercontinental lines than the Trailblazer and Hayes and later V.32bis technologies. In addition, they were also faster with firmware upgrades to support faster speeds than competing brands.

This mattered a lot to me, as initially CompuServe was only accessible by dial-up to the USA. The same for a lot of BBS and FidoNet uplinks.

For me, they weren’t any cheaper buying them (as the BBS discounts for them were not valid in Europe; I bought mine for a more than DM 1000 in Germany) but it was cheaper gaining knowledge (my motto always has been “a life long learning”).

Since the above article,

  • the Sportster magic string entry on Wikipedia vanished, but the info is still at USRobotics Sportster magic string – WOW.com,
  • I stopped using PowerLine as it wasn’t stable enough, so during the replacement of our solar panels with more modern equipment a few years ago, had CAT-6 pulled up to the utility closed on the bedroom floor.

More info about modem training and standards in this 1998 article:

Everything you wanted to know about modem and fax standards and software, but were afraid to ask is covered in this great overview article by Frank Gao from Gao Research. This article discusses all the functions that go into today’s modem products, but is not tied to any particular hardware implementation.

Compare Registry Settings – Beyond Compare – @ScooterSoftware

Posted by jpluimers on 2016/01/15

I think that Compare Registry Settings is one of the most unknown features of Beyond Compare.

So if you are a Windows that fights with the Registry every now and then, this feature is for you.

Note it is in the Windows Pro Edition only: one more reason to buy a license (:

It has been there since Beyond Compare version 3.2, and for either side of the comparison supports:

  • Your live registry
  • The registry on a remote computer
  • A .reg export file (locally or on an ftp server)

Use it to compare your registry against a backup, copy settings between PCs, and much more.

Note that comparing full registries can be slow, especially for remote registries as the registry transfer protocol of Windows is a bit chatty for the many small requests that Beyond Compare has to do.

The 2.5 minute introduction video is much better than the screenshot below, so go and watch it (:

On my research list is Netcat: the TCP and UDP swiss army knife

Posted by jpluimers on 2016/01/14

Through [WayBack] netcat 1.11 for Win32/Win64 I bumped into [WayBackNetcat – Wikipedia, the free encyclopedia.

The docs at [WayBack] Netcat: the TCP/IP swiss army made it arrive on my research list.

Time for some scripting with it (:

Getting your public IP address from the command-line

Posted by jpluimers on 2016/01/13

Many sites giving your public IP address return a web page with a bloat of html. From the command-line, you are usually only interested in the IP-address itself. Few services return exactly that.

Below are command-line examples to provide the public IP address mostly from a *nix perspective. Usually you can get similar commands to work with Windows binaries for wget and Windows binaries for curl.

In the end, I’ve opted for commands in this format, as I think akamai will last longer than the other sites (but does not include an end-of-line in the http result hence the echo on Mac/*nix):

I’ve not tried aria2 yet, but might provide commands for that in the future.

These are the Linux permutations for akamai:

curl whatismyip.akamai.com && echo
curl ipv4.whatismyip.akamai.com && echo
curl ipv6.whatismyip.akamai.com && echo
curl ipv4.whatismyip.akamai.com && echo && curl ipv6.whatismyip.akamai.com && echo

The last two are convenient when you have both IPv4 and IPv6 configured on “the outside”.

You can replace curl with wget -q -O – (which outputs to stdout) for each command. You can even ommit the http:// (as that is the default protocol for both curl and wget).

Posting from Google+ to Twitter: an #IFTTT recipe

Posted by jpluimers on 2016/01/12

A long time ago I setup to post from Google+ to Twitter.

Somewhere close to spring 2015, that stopped with a G+ tweet about FireDAC which linked to my G+ post about it.

I could not find out however how I initiated that post forwarding, so I did some searching, then decided to go the IFTTT route: 10 Easy Steps To Automate Your Google Plus To Twitter Postings – Social Media Strategies & Techniques For Business Professionals.

The page does not allow you to select text or right click, but you can view the source (for instance in Chrome with view-source:http://www.garyhyman.com/10-easy-steps-to-automate-your-google-plus-to-twitter-postings/) so I’ll summarise:

  1. Note your Google+ numeric ID. For me these were 31 digits. Lets call it ####.
  2. Append the ID to http://gplus-to-rss.appspot.com/rss/ so you get http://gplus-to-rss.appspot.com/rss/####, then verify it indeed returns an RSS feed
  3. Login to ifttt.com (create an account first if you don’t have one), then create a new THIS source from the RSS feed icon.
  4. Select the link from 2. as source.
  5. Click on the THAT link, and select Twitter (you might need to enable IFTTT for Twitter).
  6. From the Twitter list, select “post a tweet”.
  7. Amend the text if needed (remember you only have 140 characters!), then press Create Action.
  8. Test (you might need to wait for about 15 minutes): indeed it worked as my G+ post got picked up by a tweet pointing to it about 15 minutes later.

Notes:

There are more complex schemes going through FeedBurner which I didn’t try yet:

Other alternatives I might try when IFTTT stops working:

ZFS, SuperMicro, ESXi passthrough, CrashPlan and other links

Posted by jpluimers on 2016/01/11

Some great blog entries to read:

And:

Finally:

All of the above are somehow related to the Superserver SYS-5028D-TNT4.

When looking at some pictures from the above posts, then an M1015 HBA should be perfect for ZFS (lots of results for ESXi M1015 HBA PCI VMDirectPath IO pass through, and they still seem to be the way to go for ZFS).

There might be a need for extra cooling; for some ideas: Cooling for m1015 Raid Card – [H]ard|Forum

Below are other ServerRAID OEM possibilities supporting 8 internal devices (chipset in parentheses) via:

12 Gbps adapters:

  • EUR ~180: ServeRAID N2215 (SAS3008)
    • EUR ~300: LSI 9300-8i (LSI00344)
  • EUR ~200: ServeRAID M5120 (SAS3008)
  • ServeRAID M5210e (SAS3008)

6 Gbps adapters:

3 Gbps adapters:

  • ServeRAID MR10i (SAS1078)
  • ServeRAID BR10i (SAS1068e)
  • ServeRAID BR10il v2 (SAS1068e)
