put(), get() method does not work, but list() works.

[chamsae]

Hi,
I am trying to make FTP client by this module.
List() command works well.
but put(), get() as upload, download doesn't work.
I think I tried like your example.
I will show you my source.

In case of put(),

after greeting event, ready event,
I execute this code.

ftpWrok.ftpConnection.put('./ftp.txt', 'ftpcopy.txt', function(err){
        if(err){
            console.log(err);
        }else{
            console.log("====FTP file upload success?==");
        }
    });

ftp.txt is same directory with javascript source file.
but "ftpcopy.txt" created on FTPserver just include text "./ftp.txt".
it seems not to recognize first parameter input filename but just String.

In case of get(),

ftpWrok.ftpConnection.get('./ftpTest/ftp.txt', function(err, stream){
        if(err){
            console.log(err);
            throw err;
        }

        stream.once('close', function(){ftpWrok.ftpConnection.end();});
        stream.pipe(fs.createWriteStream('ftplocalcopy.txt'));
    });

emitted error.

console.logs are like below,

==============FTP greeting event===
=============FTP ready event===========
(execute download command)
===========FTP error event=========
{ [Error: OOPS: vsf_sysutil_recv_peek: no data] code: 500 }
===========FTP error event=========
{ [Error: OOPS: child died] code: 500 }
============FTP end event====
===========FTP close event====

if I have a mistake, could you comment some advice?

[chamsae]

In put(),
now, I see relative path is server.js not javascript sourcefile included command code.
I changed path './routes/ftp.txt', then it uploaded successfully.
absolute path is not used '' but '/', it is my mistake!

but, In get(), not yet, I don't know why doesn't work.

[mscdex]

For your get() issue, can you enable debugging by setting debug: console.log in the object passed to connect() and upload the resulting output?

[mscdex]

Also, are you able to successfully transfer this same file on the same server with a different ftp client?

[chamsae]

hi mscdex!, yes, in FileZilla FTP client works very well, upload and download both. same FTP server.
um.. how can I set debugging? is there an example about this?

[mscdex]

@chamsae set debug: console.log in the object you are passing to connect() and post the resulting console output here.

[chamsae]

I am sorry not to understand your meaning. I'm a newbie for english, nodejs.
I didn't understand what does put in "console.log( ? );"

[mscdex]

Example:

ftp.connect({
  host: '127.0.0.1',
  user: 'foo',
  password: 'bar',
  debug: console.log // <-- add this line
});

[chamsae]

OK! thank you for giving example!

[mscdex]

Ok, that's a different error. Can you provide the output that generates the 'vsf_sysutil_recv_peek: no data' error?

[chamsae]

path is like below.

[mscdex]

What if you try using '/www/galleryImage/sdf222222s.txt', without the '.' in front? Or change to the 'www' directory, then to the 'galleryImage' directory, and then try get()'ing 'sdf222222s.txt'?

[chamsae]

Ok. I'll try that.

and I don't know why.. no more occur first error "[Error: OOPS: vsf_sysutil_recv_peek: no data] code: 500".
now, it just occurs "Error: ./www/galleryImage/sdf222222s.txt: No such file or directory".
it maybe just path error.

[chamsae]

WOW suceess download. thank you very much, mscdex!!!
it just because '.' in front!

[chamsae]

and I have another problem just now about connection, could you answer more?

[mscdex]

sure, go ahead

[chamsae]

You looks very kind, thank you.
I start,

I want to keep FTP connection for forever until I shutdown Express Server though not transferring file or listing.
but default setting seems to disconnect after 900 second, and emit error.
where can I edit code?

===========FTP error event=========
{ [Error: No transfer timeout (900 seconds): closing control connection] code: 421 }
============FTP end event====
===========FTP close event====

events.js:71
throw arguments[1]; // Unhandled 'error' event
^
Error: watch ECONNRESET
at errnoException (fs.js:806:11)
at FSEvent._handle.onchange (fs.js:824:26)

[chamsae]

or I think,
It would be fine, it reconnect when need to transfer.
In normal case of FTP Client Program like FileZilla, it seems do that.

anyway, I tried reconnect after disconnect(maybe.. 'close event').
is it a right way?

c.on('close', function(hadErr){
console.log("===========FTP close event====");

c.connect({
    host : localhost,
    port : 21,
    user : 'myname',
    password : 'mypass',
    debug : console.log
});

});

simply, I want to fix the error "Error: No transfer timeout (900 seconds): closing control connection] code: 421",
and automatically reconnect when need transferring file.
could you comment me how can I do?

[mscdex]

Ok, the keepalive mechanism should be fixed in c7aecf3. Give it a try with npm install https://github.com/mscdex/node-ftp/tarball/master. By default it will perform a NOOP every 10 seconds.

[chamsae]

it maybe works!

NOOP
< '200 NOOP command successful\r\n'
Parsed response: code=200; buffer='NOOP command successful'

then, after setting like this, never close connection?
this is what I want, but I don't know whether this is good way.
FileZilla FTP Client seems to reconnect if need transferring, after quickly closing.
how do you think about this?

c.connect({
host : localhost,
port : 21,
user : 'myname',
password : 'mypass',
debug : console.log
keepalive : 30000
});

[mscdex]

You could probably do both: rely on keepalive and reconnect if disconnected. It's difficult to say if any given server will kill a connection if it sees the client is just continually sending NOOPs. I would hope most would not though and would keep the connection open.

[chamsae]

Ok, thank you mscdex.
I don't know whether have bothering you today many time.
you are good programmer. see you later.
