Yes, I think this could be the problem. The end result is that the plugin does not get the output of the command.
On my two *buntu systems, 32 & 64 bits I get

$ ls -l  /usr/bin/OCPNsenc
-rwx-----x 1 root root 1839809 Jan 15 23:03 /usr/bin/OCPNsenc

Which means that all users can execute without using "sudo".

Try this command

 sudo  chmod 701 /usr/bin/OCPNsenc

Test the plugin again.

Hello Dave,

What can trust granted to OpenCPN software .... ?

This is a serious question I'm sorry to ask here but we can not leave unanswered.

There some day, installing the plug-in S63, the firewall of my PC asked me if I agreed that the software communicates through my private network with the outside.

This morning, in the new installation I made, I wanted to test the plugin WMM (wmm_pi18_v07a_win32_pi). I try to activate it. And this new window is opened. This means qu'OpenCPN attempts to communicate with the outside. (see join screen copy)

This is not normal. It never was intended, unless I did not understand.

Can you explain why and how. Unless, that is more serious, OpenCPN has been hacked and malicious people the opportunity to "enter" our computers.

Again, I apologize to create suspicion by asking this question.

Best regards, Gilletarom.

I'm pretty sure it was intended like that. The plugin will make a fingerprint from you computer, and then send this to the o-chart server.

You can deny the plugin access, then it will probably not work.

If you really want to be sure it's not sending your creditcard information, then you should not beta test!

No this is not the case. Fingerprint does not "call home". We discarted that from the beginning in order to leave the user in control. It just creates a file on the machine it is running on.

The firewall warning from Windows does not imply necessarily that a program (OpenCPN in this case) is connecting to the external Internet.
It pops already up when a program opens a new port - for instance if one is used to communicate between OpenCPN and the OCPNsens plug-in.

Dave will probably be able to explain that better than me....

This probably has to do with the server-client structure of the plugin then!?

This would mean that the server side can be closed source so the S63 charts can be decrypted and served to the client side of the plugin and will be able to read the SENC and use it inside OpenCPN, but that is just my guess.

I thought that the fingerprint did send the fingerprint to the server of o-chart, but I guess I was wrong!

@cagney:
Hi Thomas,
I've changed the rights by chmod 755
and it works !!!!!
thanx @all

I've got the next Problem:
I have opend the Testcharts , especially the /DataExchangMedia/Test8a/permitt.txt and get the following :

could somebody help me ?

That might be a corrupted file - these charts did work for others (and myself) - Linux, Mac and Win.

Can you try to download and unzip the set again?

[Columbus488]

@bcn: yes i did it, without positive result
I could try to unpack it with another System ( Win7 for instance )

I'll be back after the result..

Succesfull on my Mac now too. Although performance is not really good, and I found a bug.

Performance:
I have a fast Mac with a core i7 16GB ram and a dedicated and integrated videocard. Enough to render these vector charts. But if I switch to "All" layers in vector charts performance is really bad, especially with soundings on. Zooming takes for ever!

Bug:
When the charts are loaded I can successful change the vector chart layers, but if I set it to Standard it will show the depth contours, all fine until I use the mouse to pan the chart. The contours are gone, and if I hit the "s" for soundings, voila they are back again!

Maybe O has got a different set of standard layers then IHO standard?

Anyway its awesome to see it actually work, I'd love to be able to use this for real!

Buying charts is also a bit of a mystery, I made an account on Chartworld, there you need to add your "ECDIS" to the system, and it needs a hardware ID (I assume this is made with the fingerprint script?) But I've had no luck with that! Maybe someone can enlighten me?

Jero,

we are at an Alpha test stage - deployment on the different platforms is the first thing to look at. Rendering and performance are the next points to pin down.

About buying charts: You will need the UserPermit for OpenCPN - another/official name for the Hardware ID. In the" S-63 Plug-in explained" document there are more details.
We are in close contact with Chartworld and receive support from them.

Buying charts should wait until the plug-in is really waterproof. Would be a pitty to spent money and later you have to throw away charts or we have to invent strange amendments or plasters.
Be patient - not having deadlines is a big advantange for us and for the quality we want to achieve. Don't want stress - but fun

Those are wise words!

I keep following the thread....

[Columbus488]

Good morning at all
Yesterday I've load and unpack the testset by Win7 and copied the unpacked to Lubuntu. But nothing works.
I have another System, marinux , it is based also by linux and by the way its realy nice as an second system on board.
I will tested it today...

[CarCode]

C488,

I am afraid marinux or navigatrix have a stripped OS without some needed libraries. But you might see...

I just tried s63_pi with Windows-XP (virtual maschine running on Mac) and got the same error messages as Columbus488 (see post #127) with Linux.
After changing OCPNsenc.exe to the version Dave has posted here for XP it works however.
So I guess the Linux version might have a similiar fault as Windows-XP version.
