The OS is Windows 64 and ghc version is 8.6.4.<br>
<br>
This is the code:<br>
<br>
import System.FilePath.Windows<br>
import Network.FTP.Client<br>
import qualified Data.ByteString as B<br>
....<br>
testFtp :: IO (Either String ())<br>
testFtp = do<br>
let host = "copecco" -- this is from my hosts file <br>
username = ****<br>
pwd = ****<br>
ftpDir = "registratie"<br>
fileToSend = "globals.pas" -- a test text file<br>
putStrLn $ "Connect to " ++ host<br>
withFTP host 21 $ \h ftpResponse -> do <br>
print ftpResponse<br>
if frStatus ftpResponse == Success <br>
then do <br>
putStrLn "Connected"<br>
loginResp <- login h username pwd<br>
print loginResp<br>
if frStatus loginResp == Success<br>
then do <br>
putStrLn $ "Change directory to " ++ ftpDir<br>
cwdResp <- cwd h ftpDir<br>
print cwdResp<br>
if frStatus cwdResp == Success <br>
then do <br>
putStrLn "Read file from disk"<br>
let ftpFn = takeFileName fileToSend <br>
fileContents <- B.readFile fileToSend <br>
putStrLn $ "File size: " ++ show<br>
(B.length fileContents) ++ " bytes"<br>
stor h ftpFn fileContents TI<br>
return $ Right ()<br>
else return $ Left $ "Ftp error cwd. Code: " ++<br>
show (frCode ftpResponse)<br>
else return $ Left $ "Ftp error login. Code: " ++ show<br>
(frCode ftpResponse)<br>
else return $ Left $ "Connect to host " ++ host ++ " failed. Code:<br>
" ++ show (frCode ftpResponse)<br>
<br>
This is the response:<br>
Connect to copecco<br>
<br>
220 (vsFTPd 3.0.2)<br>
<br>
Connected<br>
<br>
230 Login successful.<br>
<br>
Change directory to registratie<br>
<br>
250 Directory successfully changed.<br>
<br>
Read file<br>
<br>
File size: 27015 bytes<br>
<br>
*** Exception: Network.Socket.connect: <socket: 444>: failed (Connection<br>
timed out (WSAETIMEDOUT)) <br>
<br>
Everything works fine until the stor commmand. <br>
When I upload the same file with another ftp client program everything works<br>
(no permission problems).<br>
<br>
What is wrong and how do I get the result codes for the stor command?<br>
