Winbox configuration files

Posted by jpluimers on 2021/12/31

A few notes:

  • WinBox configuration files are under %APPDATA%\Mikrotik\Winbox
    • The subdirectory sessions contains binary *.viw files that seem to represent “view” configurations (the positions, dimensions and other properties of the open Windows in a Winbox session) where the * of the name seems to be an IPv4 address of a machine.
    • Directories named like 6.40.3-2932358209 and 6.43.13-695307561 contain configuration files that seem to determine what WinBox features a certain RouterOS version should reveal; files in those directories seem to always be these:
      • advtool.crc / advtool.jg
      • dhcp.crc / dhcp.jg
      • hotspot.crc / hotspot.jg
      • icons.crc / icons.png
      • mpls.crc / mpls.jg
      • ppp.crc / ppp.jg
      • roteros.crc / roteros.jg
      • roting4.crc / roting4.jg
      • secure.crc / secure.jg
      • wlan6.crc / wlan6.jg
    • There are binary files Addresses.cdb and settings.cfg.viw
    • A text file named sessionpath contains the expanded path %APPDATA%\Mikrotik\Winbox\sessions

The *.crc files contain a CRC code, presumably on the contents of the correspoding *.jg file. The *.jg files seem to contain some kind of JSON.

Reset MikroTik through LCD TouchScreen when reset button procedure fails

Posted by jpluimers on 2021/12/13

I wanted access to a supposedly reset a MikroTik [WayBack] MikroTik CRS109-8G-1S-2HnD-IN, but the default credentials did not work. Somehow, keeping the reset button pushed for almost 20 seconds also did not reset+reboot it.

Luckily, the default PIN code was still 1234 ([WayBack] Manual:LCD TouchScreen: PIN code – MikroTik Wiki) so I could reset it ([WayBack] Manual:LCD TouchScreen: Reboot and Reset Configuration – MikroTik Wiki).

After this, I changed credentials and PIN, documented configuration and credentials, and ensured there is a back-up of that documentation available.

Note: fiddling with power and reset button might have worked, though it is odd the CRS109 documentation does not mention this. PIN code worked faster, so that’s what solved my issue first.

MikroTik PoE: automatically power cycle and reboot device when it becomes unresponsive.

Posted by jpluimers on 2021/09/24

In the past I had these manual scripts to power-cycle a hung RaaspberryPi device:

/interface ethernet poe set ether5 poe-out=off
/interface ethernet poe set ether5 poe-out=forced-on

or on one line:

/interface ethernet poe set ether5 poe-out=off; /interface ethernet poe set ether5 poe-out=forced-on

I am going to try this script for the port having a Raspberry Pi on it (note: this requires a 48V power brick for the Mikrotik!) on RouterOS version 6.48.3 (stable):

/interface ethernet
set [ find default-name=ether5 ] comment="RaspberryPi" poe-out=\
    forced-on power-cycle-ping-address= power-cycle-ping-enabled=\
    yes power-cycle-ping-timeout=2m

The above has not worked for a long time as per [Wayback] No POE Power Cycle @ hEX POE – MikroTik:

But it might be fixed as of [Wayback] RouterOS version v6.47.3[stable] as per [Wayback] MikroTik Routers and Wireless – Software: 6.47.3 (2020-Sep-01 05:24):

*) poe – fixed “power-cycle” functionality on RB960GSP;

Similar issues exist on RB760iGS/Hex S, and there the fix requires new hardware in addition to firmware as per [Wayback] POE OUT issue on ether5 rb760igs (no power) – MikroTik

Note that I did disassemble both of these routers for inspection and there are obvious changes to the hardware to correct the PoE problems – most notably a completely different relay, capacitor and some minor circuit design changes.

If it still fails, I might try

[Wayback] No POE Power Cycle @ hEX POE – MikroTik: workaround script

:local ipPing ("x.x.x.x")
:local pingip
# pingip below RUNS and sets the variable
# to number of successful pings ie 3 means 3 of 45 success
# can also use ($pingip > 1) or ($pingip >= 1) both TESTED
# ($pingip >= 1) means if only 1 or 0 pings do the IF, not the ELSE
:log info ("ping CHECK script IS RUNNING NOW")
# first delay 90 b4 ping test incase this is running at POWER UP
:delay 90
:set pingip [/ping $ipPing count=45]
:if ($pingip <= 3) do={ :log warning (">95% lost ping LOSS to isp GW IP x.x.x.x via ether5 so DO POE powerCYCLE")
  /interface ethernet poe set ether5 poe-out=off
  :delay 12
  /interface ethernet poe set ether5 poe-out=auto-on
  :delay 10
  :log warning ("ether5 POE HAS BEEN TURNED BACK ON")
  :delay 90
  /system script run emailPOEresult
} else={
  :log warning ("PoeCyclePINGcheck ELSE ran so no ping loss detected by script")

Mikrotik RouterOS “/ip ssh” setting not available from WinBox and defaulting to insecure?

Posted by jpluimers on 2021/09/20

Still need to research this further:

Somewhere around 6.44, when upgrading an existing RouterOS device, this snippet became part of the configuration:

/ip ssh
set allow-none-crypto=yes forwarding-enabled=remote

A few remarks:

  • I could not find anything in WinBox that is equivalent.
  • This sounds very insecure, so I have run this script:
    /ip ssh
    set allow-none-crypto=no forwarding-enabled=no

    which makes the snippet to disappear (because they are default settings according to [WayBack] Manual:IP/SSH – MikroTik Wiki).

    Like usual, the on-line documentation is dense and insufficiently clear, hence my measure.

In the future, I need to decipher these posts (via [WayBack] winbox ssh allow none crypto – Google Search and [WayBack] winbox ssh forwarding enabled remote – Google Search):
