terminal – Can not use convmv correctly?

I'm trying to convert the encoding of names of a tree of paths with files using the convmv utility.

The folders look like this:

enter the description of the image here

Some names are typed with a transliteration. This file is correct, and I tried to change another file name.

I discover that the source coding is CP437 and that the specific coding is CP866.

When I tried to order

$ convmv --notest -f cp437 -t cp866 -r * --nosmart

I had

cp866 does not cover all the necessary characters for: "./103_5 τ¿Γ-¬" ñ "ó ¬απΓ" ú "YouTube-¬á¡á½á.mp4"

It seems I should convert it from utf-8 to cp437 at the beginning, and
was a success,

mv "./85_èᬠ¡Ñ ΓÑα∩Γ∞ ¬" ¡óÑαß¿ε ¡á "Ñ αÑú¿ßΓαáμ¿.mp4" "./85 _ ???????? ??? ??? ??? ⠯ ? ॣ ???? 樨 .mp4 "
mv "./86_èá¬" "½πτ¿Γ∞ ú" α∩τ¿σ ¬½¿Ñ¡Γ "ó ¡á óδßΓáóÑ.mp4" "./86 _ ??? ??????? ?? ?? ??? ??? Mp4 "
mv "./87_èá¬" "Γα" ¿Γ∞ φΣΣÑ¬Γ¿ó¡δ⌐ email-¼áα¬ÑΓ¿¡ú.mp4 "" ./87 _ ??? ????????????? ?? E-mail- ?? થ⨭? mp4 "

but my source folder becomes 0kb

enter the description of the image here

And I can not open any file in these folders.

Okay, so I tried again

    $ convmv --notest -f cp437 -t cp866 -r * --nosmart

I still have

cp866 does not cover all the necessary characters for: "./103_5 τ¿Γ-¬" ñ "ó ¬απΓ" ú "YouTube-¬á¡á½á.mp4"

I discovered that I could do it again and again, and the result was the same

What am I doing wrong?

uml – How do you correctly transform this text into an activity diagram (timer problem)?

This is only an excerpt from a very long text, one of which I am not sure. It's a photo booth (an automaton that makes a photo of you if you insert a coin).

Automata have a camera that records once a coin is inserted. The customer has 2 minutes to freeze the video just after the insertion of the room, so he took a picture. Then, the customer can decide if he wants to print this photo or it goes back to recording mode, so that the camera registers again in order to take a picture again. . During these 2 minutes, the client can switch from the recording mode to an image until he decides to print it.

If the customer has accepted a photo, it will be printed. If, after 2 minutes, the customer has not taken a picture to print, the last picture taken is chosen and printed. If no picture has been taken, the automaton returns the piece inserted by the customer.


I'm not sure of the beginning. So, it's clear that we have two simultaneous elements at the beginning when a piece is inserted: the camera records AND the 2-minute timer starts working. But how do you show this in an activity diagram? Can I just show these two things as an activity, like this and continue?

Edit: Here is the diagram supposed to represent Christophe's solution

And here is my old wrong schema:

linux – Windows 7 NTLM does not authenticate correctly with Ubuntu 18.04

Today, I have spent most of my day trying to figure this out … This is not exactly what I had in mind for today. .. but I could not stop it … That's the problem:
My Windows 7 machine will not authenticate (for a Samba share) on my Ubuntu 18.04 system. I think I linked to the protocol itself, but I do not know exactly what the real problem is. It may be a setting I miss somewhere in Windows, although I have not messed around with the NTLM authentication settings of the local strategy. My Macintosh file sharing connection to Ubuntu works well ..

So, here's what I found:
1) Windows is resetting the connection from the Ubuntu 18.04 server and restarting the negotiation process with another port (where my Mac simply receives the STATUS_LOGIN_FAILURE message and continues its path).
2) Windows sends a different user to the Ubuntu server (eg system_name root as opposed to my Mac sending system_name root) (notice the 2 backslashes instead of 1?)
3) Windows sends an "unknown message type" to Ubuntu where, as my Mac does not send anything at all.

Here is an image of a comparison between the 2 protocols.

Packet capture comparison

I've met a few sites that can help:
https://winprotocoldoc.blob.core.windows.net/productionwindowsarchives/MS-NLMP/[MS-NLMP]-171201.pdf

https://docs.microsoft.com/en-us/windows/desktop/FileIO/microsoft-smb-protocol-and-cifs-protocol-overview

https://msdn.microsoft.com/en-us/library/cc246324.aspx

I've been converting the package captures of my Mac and my Windows 7 system into .csv files and placing them here for your viewing pleasure.

Any help would be greatly appreciated (especially from anyone working with Microsoft who knows these protocols and what they should look like)

Thank you,
John Byrne
