SAMD about arduino-ftp-server HOT 79 CLOSED

Hi,
Did you configure Filezilla for using the primary connection for data transfers ?
Did you try to uncomment #define FTP_DEBUG and #define FTP_DEBUG1 in FtpServer.h ?
Did you read the discussion about the library in arduino forum ?
https://forum.arduino.cc/index.php?topic=182382.0

from arduino-ftp-server.

yes
yes
no

Today it works, but I only changed Debug and Serial with SerialUSB
I have not changed anything in the Ethernet library.
There is something unstable, I'll see in future trials.

One thing.
I need to know, inside the loop, when it is ended the connection, for process received files.
But you've put all the information private.
How can I do ?

Hi
Good news that you were able to get the library to work
I never test my library with an Arduino Zero ( original or clone) but according to documentation, replace Serial by SerialUsb is specific to Arduino Zero family.

I need to know, inside the loop, when it is ended the connection, for process received files.
But you've put all the information private.

Yes, writing a class, it is good practice to put private variables not used by external code.
But it is a good idea to make the state of the server accessible.
I think it is quite simple:
Variable cmdStage reflect the state of the server. It can take value described by enum ftpCmd. See FtpServer.h
So, make the following changes:
In **FtpServer.**h at line 97 replace
void service();
by
ftpCmd service();
In FtpServer.cpp at line 98 replace
void FtpServer::service()
by
void FtpServer::service()
at line 107
return;
by
return cmdStage;
and before end of fonction service() (line 192), add
return cmdStage;

So, in your loop(), when ftpSrv.service() return 0 (value for FTP_Stop), you know than the server is idle.
Please, tell me if this is working, as I can't test it myself right now.

Note that you can uncomment line 43 in FtpServer.h in order to print values of variable cmdStage.

from arduino-ftp-server.

Then you made Change on the library and i test for you ?
Add also
#define SerialTest Serial // SerialUSB

And about router/NAT, you are able to access from outside ?

I opened the port 20 21 TCP, but it tells me
Status: Connection attempt failed with "ECONNREFUSED - Connection refused by server".

I have tryed.
Also Without Test work well.

from arduino-ftp-server.

Hi
I am not sure to understand you (my english is not very good)
So you make the change and they give you the desired result?
In that case, I shall publish them when I have some time.

And about router/NAT, you are able to access from outside ?

Yes, You must configure the client in passive mode.
Note that according to my experience and that of other users, FTPRush give better results than FileZilla.
Please take a look at the discussion on the forum, it will help you understand the usage of this library and resolve some issues

from arduino-ftp-server.

I created my first folk, and I made the changes you requested.
But I do not receive 0 but I get the first 1 then 2

Hi

I do not receive 0 but I get the first 1 then 2

You are right. I admit that I wanted to answer too quickly.
As briefly and badly described in definition of enum ftpCmd:
Values of cmdStage 0 and 1 are transients
Value 2 indicates the serveur is waiting for a connection (idle)
Values 3 and 4 are for authentication
Value 5 indicates that client is connected.

So, I think you can use in your loop()
if( ftpSrv.service()) > 2 )
to know that the server is busy.
Please tell me if this solves your needs.

About the access from outside
I have an application running at home. Give me some time to test access outside the local network

from arduino-ftp-server.

Yes, this solves My needs.

I have also the need to change user passwords and runtime.
Also I put this in the folk, then, if you want, you can make folk back.

I'm trying with filezilla, because I need the function to edit text files, remotely.

from arduino-ftp-server.

Yes, this solves My needs.

Good. I would update the code when I had time

I put this in the folk

I am sorry, I don't understand the meaning of "folk". Can you explain me?

from arduino-ftp-server.

https://github.com/gioreva/Arduino-Ftp-Server
This is folk of your project.
I have made and tested change on this folk.

After I add user passwords and runtimes.

I think you can accept the changes, and make a folk back
Import automatically changes in your project.

from arduino-ftp-server.

This is folk of your project

Ok! Good work!
But I think the correct word is not folk (like people, humans...) but fork (like branch)

I warn you when I test remote access

from arduino-ftp-server.

Haaa, ok, folk, fork

No, is not my project.
Is your project, with change that you have proposed.

And small other.

from arduino-ftp-server.

I'm trying to use SdFat

#include <SdFat.h>
instead of
#include <FatLib.h>

But it will not compile:

Hi giovera
This morning I took out an arduino due from the bottom of my drawer, as well as a wiznet module.
It has been two years since I compiled this library ...
I just finish to compile FtpServerTest (the example)

from arduino-ftp-server.

You have done a great job.
I would have thought that such a beautiful work was known and widely used.

I design cards, these:
https://shop.gevaelettronica.it/en/3-arduino-compatible

I'm not very good with software.

I was wrong to remove this.
#include <FatLib.h>

I'm trying to change SdFat, But I can not find where it is included.

from arduino-ftp-server.

To use FtpServerTest with SdFat.
You have to install FatLib and SdFat in your library.
Then, in file FatLib.h uncomment line 33 and comment line 34:

#define FAT_USE  FAT_SDFAT
//#define FAT_USE  FAT_FATFS

I guess you have to modify some defines according to your hardware
I would like to know:
-what is exactly your hardware?
Your Arduino Zero is original from Arduino? , Adafruit?, an other clone?
Your ethernet module is a wiznet5500.
Your card reader?

from arduino-ftp-server.

Our messages crossed :-)

from arduino-ftp-server.

Impressed by your web site!

from arduino-ftp-server.

It all works perfectly, just the NAT does not work. I think it's the cause is router (Provided by the internet provider).
Now I try different ports.

I would use SdFat because already use in other parts of the program.
I think using the same LIB, will save space in RAM / Flash

Only now I see that the FatFS you made it.
But it is 100% compatible and faser ad SdFat ?
All function work same ?

from arduino-ftp-server.

FatLib is mainly a wrapper that allow you to write a program regardless of the library you will use to access the memory card or spiffs (with esp8266)
For example, in case of FtpServer, you can switch from one library to an other without modifying a line of code.
When possible, FatLib fonctions are direct calls to SdFat, so the speed is the same and the code size is almost equal.
Look at the readme.md and the example.
Unless you have a very specific use, you should not have a problem. If not, notify me

Additionally, I have included functions to handle file timestamps and to read strings and integer values in decimal and hexadecimal form. This can be interesting if you use files to configure your devices.

from arduino-ftp-server.

Buongiorno
Sorry, my italian knowledge doesn't go much further :-).
I am french and I lived a very long time in Venezuela. Now back in France, at Lyon.
I investigated what appens with ftp server when accessing it from outside of the local net.
First, it is necessary to redirect ports 21 and 55600 on the router to which the server is connected.
Port 55600 is used by the server as the data port in passive mode. It is defined in FtpServer.h
Under a Windows pc, Filezilla connect to server, but can not retrieve directory list. Opening data connection fails.
Using FtpRush, it managed to open the connection but only after switching to active mode and taking a variable time.
I think I found the reason: the server sends its own local ip address instead of the external ip address of the router.
Please give me a moment to check this and see how to fix it.

from arduino-ftp-server.

Buongiorno anche a te.

My router does not open the port 21
I Believe That the provider uses it to do maintenance
I moved to the 2121 port commands work, but does not list dir.

Even one of my friends said the same IP external/internal

I solved by finding a function, service mapping, in the router.
Work active or passive.

But I do not know how many routers have such an intelligent function.

I'm working to make user and password, modifiable runtime, on RAM
But there are many changes, I do not know if you put them in the folk

You have create FAT_FS. disk inside library.
For not create new one i'm using your, but name is not good for this.

File = FAT_FS.open("in1_off.wav");
AudioZero.play(File);

from arduino-ftp-server.

Hi

My router does not open the port 21

Yes, it is possible to translate the port number in the rule you add in the router, or to configure the ftp server to use an other port.

I'm working to make user and password, modifiable runtime

Thank you for all your comments. They help me improve the library.
Instead of modifying defines in FtpServer.h it will be better to have the oportunity to call functions inmain routine for configuring ports and credentials.
I put it in my todo list.

FAT_FS usage:
I am not sure to understand your example. Can you send me the code you would use with SdFat library?

from arduino-ftp-server.

byte mac [] = { 0xde , 0xad , 0xbe , 0xef , 0xfe , 0xef };
IPAddress serverIp( 0, 0, 0, 0 );

File File;
// SdFat SD;
FtpServer ftpSrv;


void setup()
{
  initSD();

  Ethernet.init(10);
  delay(500);
  
  if (Ethernet.linkStatus() == LinkON){
    if( Ethernet.begin(mac) ){
      SerialUSB.println("ETH OK");
      ETH_USE = 1;
    }  else  SerialUSB.println("ETH FAIL");      
  } else SerialUSB.println("ETH Link Off");      
  
  if(ETH_USE) ftpSrv.init();

}

void loop(){
  if(ETH_USE){
    newSt = ftpSrv.service();
    if( newSt != oldSt ){
      SerialUSB.print("Nuovo Stato  ");
      SerialUSB.println(newSt);
      oldSt = newSt;
    }
  }
}

void initSD()
{
  
 if (!FAT_FS.begin(SD_CS,SD_SCK_MHZ(12))) errorLed(0,0,1,"01-Inizializzazione SD fallita !");

 if(FAT_FS.exists("firmware.bin")) FAT_FS.remove("firmware.bin");

  File = FAT_FS.open("config.ini");
  if( getFieldSD("enableSmsOn=")   == "1" )   enableSmsOn   = 1;
}

from arduino-ftp-server.

Can you replace
File File;
with
FAT_FILE File;

And tell me the result.

Note: IMO, it is better practice to use different names for variables and their constructors. And that they don't begin with capitalized letter
FAT_FILE file;

from arduino-ftp-server.

The authentication will not work anymore.

FtpServer.h
//#define FTP_USER "arduino"        // User'name
//#define FTP_PASS "test"           // His password

FtpServer.cpp
extern char *FTP_USER;
extern char *FTP_PASS;

.ino

char FTP_USER[15];     // FTP User'name
char FTP_PASS[15];     // FTP password

getFieldSD("FTPuser=").toCharArray(FTP_USER, sizeof(FTP_USER));
getFieldSD("FTPpassw=").toCharArray(FTP_PASS, sizeof(FTP_PASS));
SerialUSB.println(strlen(FTP_USER));
SerialUSB.print(FTP_USER);
SerialUSB.println(";");

The Debug are Ok, but using gevino, gevino not log in

6
gevino;

from arduino-ftp-server.

File File; is made of "Replace All"
But Work, have not created problem.
In any case I changed.

from arduino-ftp-server.

Hi
I have resolved the access from the outside network.
I have to clean the code and shall send it to you.

from arduino-ftp-server.

Good, perfect
But the change on my fork ?

from arduino-ftp-server.

Hi
I just update the repository of ftpServer.
Please download it, update the library and read and try the two examples FtpServerTest and FtpServerStatusLed

In your code, do not modify the Serial but try the following
Add this 4 lines at the beginning of your main code as explained there:
https://learn.adafruit.com/adafruit-feather-m0-basic-proto/adapting-sketches-to-m0

#if defined(ARDUINO_SAMD_ZERO) && defined(SERIAL_PORT_USBVIRTUAL)
  // Required for Serial on Zero based boards
  #define Serial SERIAL_PORT_USBVIRTUAL
#endif

It depends of your hardware and I can not try it. Please tell me if this work.
Now I have to update the discussion on the forum and give more details on these modifications
Thank you for your patience

from arduino-ftp-server.

What is this code ?
On my board exist. (All Working)
SerialUSB
Serial
Serial1
Serial2
Serial3

from arduino-ftp-server.

Honestly, I have not investigated.
Just now I make a search in the ide software::

It depends on the hardware.
It will not hurt to try.
I think you can also try by replacing SERIAL_PORT_USBVIRTUAL by SerialUSB

Looks like the server hangs.
Please, remove this 4 lines and replace them simply with
#define Serial SerialUSB

from arduino-ftp-server.

Cannot
Boot exist. Serial and SerialUSB
Cannot be overwritted.

On my Folk i have used
SerialTest on the code.
And define
#define SerialTest SerialUSB
#define SerialTest Serial

Replacing all Serial with SerialUSB, now consolle is:

There are not Welcome message.
But now list file work

I do not understand why with Serial the file list does not work

from arduino-ftp-server.

Welcome is there only when auth fail.

Yes, it looks like FileZilla don't show the same information when connecting to a server on an outer network.
May be a security measure?
I am probing with FileZilla and ftpRush. They don't react always in the same way!
I see than you configure FileZilla to use port 2121. Did you modify #define FTP_CTRL_PORT 21 in FtpServer.h or did you configure the router to make the transfer?

from arduino-ftp-server.

I am reading about Due specification. The board also as a native usb port.

I suppose you use the arduino ide.
Can you tell me wich board you select in the ide?

from arduino-ftp-server.

Arduino zero, native USB port
Need to be install ARM compiler.

I have set 2121 boot, on define and on filezilla.
My router do not open 21 port, is busy.

This message (welcome) is locally, not external ip.

Using external ip, now list dir work well

from arduino-ftp-server.

What is the problem, this change crash all ?

FtpServer.cpp
extern char* FTP_USER;
extern char* FTP_PASS;

.ino
char FTP_USER_[15] = "arduino"
char FTP_PASS_[15] = "password"

from arduino-ftp-server.

Now you can set username and password in your code without modifying the library.
In repository that I upload yesterday, please have a look at the updated example FtpServerTest, line 118

from arduino-ftp-server.

Grazie
Now my project is complete and it works well.
Missing only the Welcome, you can not fix it?
I put your library and example on the GEVINO document/examples

Can you change to const char* ?
ftpSrv.credentials(const char*, const char* )

String.c_str() return const char* pointer
ftpSrv.credentials( (char*)getFieldSD("FTPuser=").c_str(), (char*)getFieldSD("FTPpassw=").c_str() );

Can you add port to ftpSrv.credentials, or make new function for it ?

Maybe your FTP can work with Telnet server ?
https://gist.github.com/atomsfat/1813823

There are not library for esy make telnet server,if you have time for make it.

from arduino-ftp-server.

Hi
Glad to know that your project is working!
There are several points in your last message. I will try to answer all.

Missing only the Welcome

I do not understand. Wich welcome and where?

Can you change to const char* ?

Yes, I did it in the last update. I am thinking of upload it today. But this time, I am thinking to better checkevery thing first. These days I had uploaded the changes too quickly in hopes of resolving your remarks and this led to somes errors on my part.

Maybe your FTP can work with Telnet server ?

Yes, they are independent services and can work in parallel. W5500 has enough sockets for that.
You just have to make sure that the different services are non blocking.

from arduino-ftp-server.

It depends on the filezilla configuration, not the server

Be sure to check this box before connecting to the server.

Or try FTP Rush. It less complicated. And you too can edit files on the server :-)

from arduino-ftp-server.

yes
Same problem accessing on Linux FTP server.

from arduino-ftp-server.

Thank you to confirm!
Protocol for FTP has evolutionned in the time and each client or server has his own particularities and do not always respect perfectly the protocol.
So it is a good practice to make test with different clients and servers as you do and as I do myself.
This afternoon I have uploaded some changes and I hope than they are definitives, at least for the moment...
In particular, I believe that example FtpServerTestSerialUsb will be of interest for you.

On the other hand, if you don't want to rewite the complete code, I suggest you to see the four lines I add in FtpServer.cpp
Replace line 229
client.stop();
with

  if( client )
    client.stop();
  if( data )
    data.stop();

The reason is that sometime, when my friend FileZilla does not finish correctly a transaction, the server was not closing the corresponding socket.
After several fails, all sockets are in use and server crash.

from arduino-ftp-server.

Very Good.

I can upload firmware via FTP now.
When client close the connection, if there is a file "firmware.bin" on SD, I reboot the micro and updating firmware.

You have not added way for change port Runtime ?
It is not essential, but cute.

from arduino-ftp-server.

I have downloaded FTP Rush
But i don't find way for edit config.ini, text file, directly inside Client.

from arduino-ftp-server.

Right click on the file open this menu:

from arduino-ftp-server.

My FTP RUSH is different.

from arduino-ftp-server.

I now realize that the version of FtpRush I am using is very, very old !

What a shame!

from arduino-ftp-server.

from arduino-ftp-server.

Exist V2 and V3.
But FileZilla Work well.

from arduino-ftp-server.

Ok,
I tried the V2 but is a continuous crash.
Do not download files.
Just reopened FileZilla has downloaded them.

from arduino-ftp-server.

Ja ja ja. Using a software 9 years old. May be I should update it...

change port Runtime

Yes, it would be nice something like:
ftpSrv.init( commandPort, dataPort, externalIP );
but, until now I do not know how to instantiate a server object without define his port number.
So, the only solution at the moment is to modify the #define in FtpServer.h

I have updated the discussion in the forum and thank you for your suggestions

from arduino-ftp-server.

Hi
I updated to the version V2.2.0 from FtpRush. Looks like V3 is beta
It is working fine here.
But if you are satisfied with FileZilla, that is all right.

Something we do not discute:
If the client crashes without closing the connection (for example if the computer it is running on loses its connecttion to the internet), the server does not close immediately (because it has no way to know about the crash).
Consequently, you can't reconnect until the server closes the connection.
This time lapse is defined by FTP_TIME_OUT in FtspServer.h and I set it to 5 minutes. But you can reduce it if you will.

from arduino-ftp-server.

Thank you.

I already switched to another project, but I would still experience here.
For example, I wanted to see if it was possible to enable uPnP

The problem is that opening the port is difficult and not very functional.
It works very well open the FTP service but do not know if uPnP can do this.

from arduino-ftp-server.

I have no experience with uPnP.
if I am not mistaken, the interest is to facilitate the configuration of the router behind which is connected a device (for example, your Gevino Zero)?

I have a question: You told me you are updating the firmware from a file uploaded to the SD.
This is interesting. Can you tell me which library you use for that?

from arduino-ftp-server.

I have created custom bootloader for SAMD21, but need hardware programmer.

Hi
Library work well, but IDE at startup says ?

"Invalid library found in C:\Users\x-gio\Documents\Arduino\libraries\FtpServer: no headers files (.h) found in C:\Users\x-gio\Documents\Arduino\libraries\FtpServer"

from arduino-ftp-server.

Hi
This is strange!
This message appears compiling one of the examples? Which one?
The editor points to a specific line?

from arduino-ftp-server.

Not, when ide start.
At startup it check all folder

from arduino-ftp-server.

All your libraries are in that folder?
My Users...\Documents\Arduino\libraries folder is empty. It only contains a file readme.txt
I have a libraries subfolder in the folder where are my sketches.

from arduino-ftp-server.

Maybe cause is missing file "library.properties" on my folder.

I'm going crazy.
Is there a conflict with the library https://github.com/stevemarple/IniFile

It was better if the file was opened in schetch and passed only the pointer to your library.

Problem is redefinition of "sd"
#define FAT_FS sd
line 43 FatLib.h

Also IniFile use same.

I can not understand what files you use sd

from arduino-ftp-server.

Hi
It is difficult to answer you without your seeing the code.
If the error goes away when you delete the Inifile library, then yes there is a conflict between the libraries.
I do not know IniFile. I just see that in IniFile.h there is a way to select library to access SD card.
Maybe you can modify this library to use FatLib, the same way I do in ftp server.
This way you will be able to choose between SdFat or FatFs by simply changing a #define in your entire sketch.

from arduino-ftp-server.

Code is simple.

#include <SdFat.h>
#include <FtpServer.h>
#include <IniFile.h>
FtpServer ftpSrv;
IniFile ini("config.ini");
void setup(){}
void loop(){}

I'm trying to change the IniFile library but all attempts have failed.
You have too many recursive libraries and I lose myself.

Help me to find right definition for
extern SdFat sd;
Line 12 of
https://github.com/stevemarple/IniFile/blob/master/src/IniFile.h

from arduino-ftp-server.

Now Work
Sorry
Forget everything

from arduino-ftp-server.

Do not worry.
I don't know a way to progress without making mistakes!

Is IniFile used in setup() to configure some parameters? In that case may be you can do it in a simpler way.

from arduino-ftp-server.

I'm desperate, I can not find a solution for use this ibrary wit IniFile
Can you help me ?
I always get "not open file".

#if defined(PREFER_SDFAT_LIBRARY)
#include "SdFat.h"
//extern SdFat SD;
extern SdFat sd;
#else

bool IniFile::open(void)
{
if (_file)
_file.close();
// _file = SD.open(_filename, _mode);
_file = sd.open(_filename, _mode);
if (isOpen()) {
_error = errorNoError;
return true;
}
else {
_error = errorFileNotFound;
return false;
}
}

Hi
Let me see if I have time this afternoon to help you

from arduino-ftp-server.

Maybe I have solved problem
Tomorrow I continue

.ino
#include <SdFat.h>
SdFat SD;

IniFile.h
#if defined(PREFER_SDFAT_LIBRARY)
#include "SdFat.h"
extern SdFat SD;

from arduino-ftp-server.

nothing, now works IniFIle but not works FTP
Only i see directory, but not work uplaod download file.

I need your help for setup disk.

"SD" "sd" "FAT_LIB"
Where and what extern define.

from arduino-ftp-server.

Not, now work

from arduino-ftp-server.

#if defined(PREFER_SDFAT_LIBRARY)
#include "ExtSdFat.h"
extern ExtSdFat sd;
#else
#include "SD.h"
#endif

from arduino-ftp-server.

Maybe you have not undestand.
I have to use same disk (sdfat) from IniFile and FTPserver

If I use config above, build work, but somtime i found SD brocken.
Also formatting is impossible, i have removed and recreated partition for save it.
