transfer

I manually copy a file to a server, and the same one to an SFTP server. The file is 140MB. FTP: I have a rate arround 11MB/s SFTP: I have a rate arround 4.5MB/s I understand the file has to be encrypted before being sent. Is it the only impact on the file transfer? (and actually this is not exactly transfer time, but encryption time). I am suprised of such results. Chris Rapier I'm the author of HPN-SSH and I was asked by a commenter here to weigh in. I'd like to start with a couple of background items. First off, it's important to keep in mind that SSHv2 is a multiplexed protocol - multiple

How i can shift one raw of data frame to first raw, i want the id raw be the first raw. in R. Sepal.Length Sepal.Width Petal.Length Petal.Width Species 5.1 3.5 1.4 0.2 setosa 4.9 3.0 1.4 0.2 setosa 4.7 3.2 1.3 0.2 setosa 4.6 3.1 1.5 0.2 setosa 5.0 3.6 1.4 0.2 setosa id A B C D We can use grepl to create a logical vector based on the 'id' in 'Sepal.Length', then set the column names of the dataset by extracting that row while removing the row from the original dataset i1 <- grepl("id", df1$Sepal.Length) setNames(df1[!i1,], unlist(df1[i1,])) # id A B C D #1 5.1 3.5 1.4 0.2 setosa #2 4.9 3.0 1.4

I would like to know if there is a way where you have a .net app name appA where it receives a tcp socket connection and then according to some rules will send the socket connection to another .net app named appB. I know this violates alot of security and good practice,but would be interesting if it would be possible. Proxy One option is to make AppA a proxy. That is, it accepts the connections, and connects on behalf the client to AppB - and merely forwards the data. Socket Duplication The solution you are really looking for is Socket.DuplicateAndClose() (make sure you read the documentation

The following code is meant to take a file (any file would be nice, but right now I'm just using images anyway), and upload it to my server (which works, blah blah blah). The only problem is that the picture is quite skewed after transfer. The main suggestion is to use FTPClient's setFileTranferMode to FTPClient.BINARY_FILE_TYPE, which... has no effect at this point... Here's the code for the method: public void sendFile(File sendMe) throws IOException{ f.connect(ip); f.login(username, password); String recipient=null; while(!f.changeWorkingDirectory(path+recipient)){ recipient=JOptionPane

I just started to learn MVC and am trying to understand how it works. I don't want to send users to different views for all edit, insert and list operations. In my sample application a View contains a list of items and below the list there is a form (for inserting new items) with action "{Controller}/Create" but there is no Create View. When a user inserts a new item it posts to the Create action with httpverb post and creates the item and returns back to the List action with RedirectToAction method. But I can not show any message(error, information etc) to the user in this style because I can

I am trying to send a file over bluetooth in an android device. I have done discovery, connection and have made a bluetooth socket. Problem is when i am writing the byte array in the output stream of the bluetooth socket, the recieving side does not receive anything although it accept that something is being sent. Here's what Iam doing (bad is the bluetooth adaptor) Please advise. try { BluetoothDevice dev = bad.getRemoteDevice(a); bad.cancelDiscovery(); dev.createRfcommSocketToServiceRecord(new UUID(1111, 2222)); Method m = dev.getClass().getMethod("createRfcommSocket", new Class[] {int.class
