Read Timout

Question

Using FileTransferClient, I'm trying to upload a small html file onto the server (it's only a few bytes). For some reason, it's started giving me a read timeout error. I say started because up to a couple days ago this wasn't happening. I don't know what I did to break it. Here's the relevant code:

   String postLoc = System.getProperty("java.io.tmpdir") +  "/" + postName + ".html";
   putFileContents(postLoc, file);
   try {
       ftpManager.uploadFile(postLoc, postName + ".html");
       ftpManager.disconnect();
   } catch (FTPException f1) {
       iom.showError(f1);
   } catch (IOException e1) {
       iom.showError(e1);
   }

The only error given is:
java.net.SocketTimeoutException: Read timed out.

I'm running this from a command line, with my desktop as the working directory, and from Fedora. The tmpdir variable is simply "/tmp".

No matter what timeout I've set it to this still happens. All it does is create an empty file on the server, but doesn't put any of the content into the remote file.

If it's relevant, I am unable to ftp to my server through a command line and issue the following commands:

quote PASV
quote LIST

The first one works to put it into passive mode, but it hangs up on the second. This also happens if I try to use a STOR command.

Answer 1

Post a log file. It could be a firewall change - try switching from passive to active mode. Can you transfer the file with another client such as Filezilla?

Answer 2

Trying a "quote PORT " also times out. As for a separate FTP client, I know that FireFTP through Firefox works just fine. I am unable to install Filezilla at this time. Here's the log file:

It's long, but I'm not sure what part of it you want to see. Most of it's the same stuff. I've bolded and underlined the parts that are different.

Answer 3

It seems clear that your socket time-out is set to 60 seconds and that it's simply timing out as it's trying to connect the data-channel. This usually happens when there's a firewall in the way.

It's not clear from your reply if tried using passive mode instead of active mode?

It's done using:

ftp.getAdvancedFTPSettings().setConnectMode(FTPConnectMode.PASV);

Answer 4

I apologize for the timeout confusion; that log is from after I changes the timeout I had been trying to a more reasonable number.

However, changing to PASV has fixed all my problems! I can finally get some actual work done! Thank you!
