sUBIR ARCHIVOS AL SERVIDOR WEB DE INTERNET CON FTP C#

[diegolo]

Hoola estoy subiendo archivos al server, en forma local si vale super pero en el internet no vale pero es por que no tengo permisos de usuario y lo hice mediante ftp en c# tan vale pero ahora sin hacer nada ya no vale que será?

GRACIAS POR LA AYUDA DE ANTEMANO

[Peterpay]

Q limitantes tiene tu hosting?
Usa certificados de seguridad?
Estas enviando por codigo via sockets o ftpclient?
que version del framework?

pon tu codigo


PD Y TARAN!!!!! Me avisas si funciono

Y LUEGO LLAMO DESDE UNA FUNCIO A TODO ESTA PROGRAMACION
ASI:
//////Clases.FTPFactory ff = new Clases.FTPFactory();
ff.setDebug(true);
ff.login();
ff.chdir("Images");
ff.setBinaryMode(true);
ff.upload(txtUpload.PostedFile.FileName);
ff.close();

Y EL RESTO QUE VA DEBAJO YA ES SOLO PARA GUARDAR LA RUTA Y EL NOMBRE DE LA IMAGEN PARA DESPUES VERLA

[Peterpay]

pregunta y porq no simeplemente hacer

WebClient client=new WebClient();
client.Credentials=new NetworkCredential(usr,pwd);
client.UploadFile("ftp://turuta/nombreEnServidor",archivo);
o

FtpWebRequest request=new FtpWebRequest();
request=FtpWebRequest.Create("ftp://aadd");

request.Credentials=new NetworkCredential(usr,pwd);
request.Method="tu comando ftp";
request.GetResponse();

se que hacer todo con sockets tiene su merito pero es extenuante estar revisando todos los errores q pueden ser simplemente por la sintaxis de tus peticiones de ftp.

De nuevo recurro a ustedes arribita puse un codigo para subir archivoas al server de internet, subia y bien, ahora ya no, me faltará algun permiso en el server porque me sube con tamaño 0

GRACIAS!!!!
