MikroTik has great hardware, but getting things to work can be a bit ehm intimidating.
So here are some links that were useful getting my CCR1009 and CRS226 configurations to do what I wanted.

ANSI HTML Adapter example
Posted by jpluimers on 2017/04/24
ANSI HTML Adapter example installation on OpenSuSE Tumbleweed:
zypper addrepo http://download.opensuse.org/repositories/utilities/openSUSE_Factory/utilities.repo
zypper refresh
zypper install aha
On Mac OS X:
brew install aha
Output looks like this: ANSI HTML Adapter example:
diaspore:/etc # aha --version
Ansi Html Adapter Version 0.4.9.0
diaspore:/etc # aha --version | grep aha
diaspore:/etc # aha --version | ahaAnsi Html Adapter Version 0.4.9.0
And the aha --help output on Mac OS X:
Ansi Html Adapter Version 0.4.8.0 aha takes SGR-colored Input and prints W3C conform HTML-Code use: aha <options> [-f file] aha (--help|-h|-?) aha reads the Input from a file or stdin and writes HTML-Code to stdout options: --black, -b: Black Background and White "standard color" --pink, -p: Pink Background --stylesheet, -s: Use a stylesheet instead of inline styles --iso X, -i X: Uses ISO 8859-X instead of utf-8. X must be 1..16 --title X, -t X: Gives the html output the title "X" instead of "stdin" or the filename --line-fix, -l: Uses a fix for inputs using control sequences to change the cursor position like htop. It's a hot fix, it may not work with any program like htop. Example: echo q | htop | aha -l > htop.htm --word-wrap, -w: Wrap long lines in the html file. This works with CSS3 supporting browsers as well as many older ones. --no-header, -n: Don't include header into generated HTML, useful for inclusion in full HTML files. Example: aha --help | aha --black > aha-help.htm Writes this help text to the file aha-help.htm Copyleft Alexander Matthes aka Ziz 2015 zizsdl@googlemail.com http://ziz.delphigl.com/tool_aha.php This application is subject to the MPL or LGPL.

Some Wireshark links
Posted by jpluimers on 2017/04/24
I don’t use Wireshark enough to be fluent, so here are some links and quotes that proved to be useful for me:
- How do I view a raw HTTP request/response? – Wireshark Q&A: Right click one of the frames and select ‘Follow’, then ‘TCP stream’.
- Hyper_Text_Transfer_Protocol – The Wireshark Wiki:Â You cannot directly filter HTTP protocols while capturing. However, if you know the TCP port used (see above), you can filter on that one.
- These two are totally different beasts: CaptureFilters – The Wireshark Wiki and DisplayFilters – The Wireshark Wiki
- I used this DisplayFilter a while ago:Â
(ip.dst == 192.168.99.61 && ip.src == 192.168.99.38) || (ip.dst == 192.168.99.38 && ip.src == 192.168.99.61) && http
which seems equivalent to
(ip.addr == 192.168.99.61 && ip.src == 192.168.99.38) && http - For SOAPAction traffic (and the HTTP responses), I often start with:Â
http contains "SOAPAction:" || http contains "HTTP" - I used these CaptureFilters a while ago as well:
src 213.146.155.196 and tcp port 8500ether host MACÂ 00:21:AC:01:08:B1
- Display filters can become very complex.
- One of the things I needed was to filter on hex content. This is using the
frame containsclause will match any binary content in the frame (you can be more specific with for instance tcp containsor data contains (which uses the data dissector). Example:(frame contains 21:00 || frame contains 00:21) && tcp.len > 0 - Some examples: Top 10 Wireshark Filters (by Chris Greer)
- The matches operator works for RegEx matches on plain text:
data.data matches "\xa4.\xc3...\xb2" - MAC addresses need to have the : as separator (a – does not work), like inÂ
eth.src == MACÂ 00:21:AC:01:08:B1
- One of the things I needed was to filter on hex content. This is using the
- I used this DisplayFilter a while ago:Â
- WIRESHARK – The Easy Tutorial – Filters
- I find the WireShark User’s Guid sections often a lot harder to read than the Wiki pages on the same topics, for instance the CaptureFilter Section and Build DisplayFilter Section.
- exporting payload data in binary file – Wireshark Q&A
- tcpdump: Re: tcpdump filter for HTTP GET
- which uses hex offsets explained at Wireshark · Wireshark-users: Re: [Wireshark-users] Hex Offset Needed
- Wireshark · String-Matching Capture Filter Generator is really really cool. It gets you
GETastcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420POSTastcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354 && tcp[((tcp[12:1] & 0xf0) >> 2) + 4:1] = 0x20
- Capture file saving:
- capture files do not store everything.
- From the UI, you cannot save captures while capturing.
- You can setup capture options to save captures periodically.

Posted by jpluimers on 2017/04/21
For future research: opensuse – How to run my script after SuSE finished booting up? – Unix & Linux Stack Exchange
Reason? Want to show the output of this as the last boot sequence line:
hostname
ip route
echo
ip address | grep -w 'UP\|flags\|inet\|inet6'
echo more detailed info through "ip address" and "ip route"
cat /etc/resolv.conf | grep nameserver

Tested the CastBuddy extension from the Chrome Web Store: nice, but high CPU usage even when no videos
Posted by jpluimers on 2017/04/21
This extension finds videos on the web sites you are browsing and allows you to play them on your Chromecast device.
Works nice if you need it, but uses a lot of CPU (on my Retina MacBook with latest chrome: about 75% of one CPU core) so it drains battery fast.
You can view this high CPU usage in the Chrome Task Manager (which used to be available through chrome://tasks, but this is one of the use full Find Hidden Features On Chrome’s Internal Chrome:// Pages features they removed). Fire up the Chrome Task Manager through the Window menu.
Verdict
Enable only when you need it. Disable after use in chrome://extensions
–jeroen
via: CastBuddy – Chrome Web Store:
When it finds Chromecast comptible videos ( .webm, .mp4, .mkv etc), count of videos is shown over extension’s menubar icon, which you can click to Select a video and extension will send it to your Chromecast device. Once a casting session is established, you can control video playback from Extension’s popup page.

Warning: C64 geek pr0n! A Mind Is Born

Geek pr0n on the C64:
Making a demo in just 256 bytes would be a formidable challenge regardless of platform. A Mind Is Born is my attempt to do it on the Commodore 64. In the absence of an actual 256-byte compo, it was submitted to the Oldskool 4K Intro compo at [WayBack] Revision 2017, where it ended up on 1st place.

use vmrun – via How do I find the IP address of a virtual machine using VMware Fusion? – Super User
Posted by jpluimers on 2017/04/20
Note this works only when the VMs have VMware Tools installed (more on that below):
VMWare provides, not surprisingly, a built in tool for this, vmrun. It’s under
/Applications/VMware Fusion.app/Contents/Library/vmrunalthough it has moved around in other Fusion releases a bit.
🍺 vmrun list Total running VMs: 1 .docker/machine/machines/myvm.vmx
🍺 vmrun getGuestIPAddress ~/.docker/machine/machines/myvm.vmx 172.16.213.128
via: How do I find the IP address of a virtual machine using VMware Fusion? – Super User [WayBack]
vmrun [WayBack] is barely documented and most of is in PDF of which this is the most recent I could find: www.vmware.com/pdf/vix180_vmrun_command.pdf [WayBack]
Based on the above path, I added this to my ~/.bash_profile file:
alias vmrun='/Applications/VMware\ Fusion.app/Contents/Library/vmrun'
alias vmrun-list-running-VMs='vmrun list | grep vmx'
vmrun-list-ipv4-of-running-VMs()
{
vmrun-list-running-VMs | while read line ; do echo $line && vmrun getGuestIPAddress $line; done
}
Now I can do this:
$ vmrun-list-ipv4-of-running-VMs
/Users/jeroenp/VM/W81Entx64DelphiRegression.vmwarevm/W81Entx64.vmx
172.16.172.135

These are the messages I observed:

The first one means a machine is running but has no VMware Tools installed. For an OpenSuSE machine you can install it with zypper install open-vm-tools, for other Linux systems read VMware Tools auf Ubuntu, Mint, CentOS oder openSUSE installieren | ITrig [WayBack]

Dark corners of Unicode / fuzzy notepad
Posted by jpluimers on 2017/04/20
You think you know Unicode? Think again, then read [Wayback] Dark corners of Unicode / fuzzy notepad.
On basics, sorting, comparison, decomposition, composition, width, whitespace, encoding, emoji, interesting code planes and dark corners. Lots of dark corners.
The examples are in Python, but hold for almost any programming language
