Manual:CRS examples – MikroTik Wiki

Posted by jpluimers on 2017/08/22

The Cloud Router Switches support three types of mirroring. Port based mirroring can be applied to any of switch-chip ports, VLAN based mirroring works for all specified VLANs regardless switch-chip ports and MAC based mirroring copies traffic sent or received from specific device reachable from the port configured in Unicast Forwarding Database.

Port Based Mirroring

The first configuration sets ether5 port as a mirror0 analyzer port for both ingress and egress mirroring, mirrored traffic will be sent to this port. Port based ingress and egress mirroring is enabled from ether6 port.

/interface ethernet switch
set ingress-mirror0=ether5 egress-mirror0=ether5

/interface ethernet switch port
set ether6 ingress-mirror-to=mirror0 egress-mirror-to=mirror0

This allows you to torch traffic from a specific port despite that port being grouped to a master-port.

Via: Torch not working with CRS226-24G-2S+ – MikroTik RouterOS [WayBack]

But, when using Bridge, all ports share a single 1 gbps link to the CPU, so your layer 2 performance will suffer horribly.

If you need to see all the traffic from a single port when using Master/slave port configuration, use port mirroring.

MAC-Telnet: Open source MAC Telnet client and server for connecting to Microtik RouterOS routers and Posix machines via MAC address.

Posted by jpluimers on 2017/08/22

Found out about this a while ago:

MAC-Telnet – Open source MAC Telnet client and server for connecting to Microtik RouterOS routers and Posix machines via MAC address.

Source: haakonnessjoen/MAC-Telnet: Open source MAC Telnet client and server for connecting to Microtik RouterOS routers and Posix machines via MAC address. [Fork]

Background:

Earlier, I wrote about a Wireshark plugin for dissecting Mac-Telnet packets. Now I have created an open source application for connecting to a RouterOS router.

My previous post was about RouterOS Mac-Telnet application for Linux users where I talked about the MAC-Telnet client I created for Linux users.

Twitter image size suffixes – via: Making silly #latex jokes is much more fun than doing final tweaks in my thesis on #coeffects…

Posted by jpluimers on 2017/08/18

Twitter stores images on twimg.com in various sizes.

You specify the size by adding a colon plus suffix to the URL. No colon plus suffix means a default size.

Suffixes you can use see to come from the media entity in Entities in Objects | Twitter Developers:

  • thumb
  • small
  • medium
  • large

There is one undocumented size: orig

The default size seems to be medium.

Examples (full images below):

media entity observed size URL
thumb 150×150 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:thumb
small 340×325 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:small
medium 600×573 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:medium
(none) 600×573 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png
large 1024×979 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:large
orig 1600×1529 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:orig

Thanks to Thomas Petricek [WayBack] who poked fun last year on Twitter [WayBack] at both LaTeX and O RLY (the image meme [WayBack], not the text meme)

Great diagram on composing a LINQ query – via Mastering C# – CodeProject

Posted by jpluimers on 2017/08/17

One of the best to graphs diagrams of LINQ I know is in Mastering C# – Lecture Notes Part 2 of 4 – CodeProject [WayBack]

The LINQ explanation in that article [WayBack] is top notch as well. Thanks Florian Rappl [WayBack]!

Closed: HDD Guardian – Home

Posted by jpluimers on 2017/08/16

Too bad: it was fun while it lasted.

Mid april 2017 [WayBack] HDD Guardian – Home closed down, so the latest commit removed all the [WayBack] HDD Guardian – Source Code.

HDD Guardian provides a Windows front-end for smartctl, a utility which monitors your hard drive(s) and SSD(s) for health status, taking advantage of S.M.AR.T.

The WayBack machine and Archive.is have archived some links though:

Anyone interested in getting it before codeplex itself shuts down:

git svn clone https://hddguardian.svn.codeplex.com/svn

Edit 20210909:

Note that a while ago, the salvaged source code got pushed to GitHub: [Wayback/Archive.is] native-api/hddguardian: A GUI app to watch and manage HDDs’ S.M.A.R.T., based on smartmontools. Salvaged from https://hddguardian.codeplex.com

What is the right way to convert into UNIX timestamp from the date and time in C/C++? – Stack Overflow

Posted by jpluimers on 2017/08/16

Thanks R.. for answering this:

POSIX has a formula for exactly what you want:

http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_15 [WayBack]

tm_sec + tm_min*60 + tm_hour*3600 + tm_yday*86400 +
    (tm_year-70)*31536000 + ((tm_year-69)/4)*86400 -
    ((tm_year-1)/100)*86400 + ((tm_year+299)/400)*86400

This works whenever you have a broken-down time in GMT, even if the underlying system’s mktime, etc. functions do not use the same format time_t as “Unix timestamps”.

If your original time is in local time, you can use mktime and gmtime to convert it to GMT using the system’s notion of timezone rules. If you want to apply your own timezone offset rules, just do that manually before using the above formula.

Source: What is the right way to convert into UNIX timestamp from the date and time in C/C++? – Stack Overflow [WayBack]

For testing and more examples: Epoch Converter – Unix Timestamp Converter [WayBack]

Hopefully this will help me getting better implementations for these:

Why doesn’t RevertToSelf undo the most recent SetThreadToken? | The Old New Thing

Posted by jpluimers on 2017/08/16

Oops: I fell in this trap as well: When you call Set­Thread­Token, [WayBack] it replaces the token. When you call Revert­To­Self [WayBack], the token is cleared and the thread no longer has a token. Maybe Revert­To­Self should have been named Clear­Thread­Token, since that would emphasize that the function erases any existing thread token, leaving the thread to inherit the identity of its host process.

Some links on Belise/Elise licensing server (yes, AppWave is dead or at least: should be)

Posted by jpluimers on 2017/08/15

Some links on the Embarcadero License Center server (formerly known as Belise and Elise) from my contributions to these G+ threads:

When for instance your workstations cannot communicate to the external license servers or you want to run concurrent Delphi/C++-Builder/RAD-Studio instances on your local network, you need to run the Elise licensing server on your network, which requires you to have a server with Java running somewhere.

Despite some of the documentation, it runs on more recent Windows versions too.

Not sure about the money: it’s just that a few clients of mine use it as it makes it easier to manage licenses when you switch contractors or not having various team members only use Delphi part of the time.

Inline code highlighting in reStructuredText – Stack Overflow

Posted by jpluimers on 2017/08/15

To inline code inside reStructuredText embed it with back-ticks and pre-pend the first back-tick with :code:

This is how some text with :code:`a = b + c` embedded will look like.

This is how some text with a = b + c embedded will look like.

Source: Inline code highlighting in reStructuredText – Stack Overflow [WayBack]

The above is in addition to the a = b + c that renders to default code as described for instance by reST – reStructuredText — Sphinx/Rest Memo v1.0-14-ga2798e1 documentation [WayBack]
