Experience with SFTP Clients


Say you want to transfer files over a network in a secured mannar.Here comes the usecase of SFTP[Secure File Transfer Protocol].SFTP is a secured protocol which is an extention of the Secure Shell protocol(SSH) provides capabilities as file accessing,file transferring and file management.

This protocol encrypts both commands and data and ensure not transmitting of passwords and sensitive information over the network.SFTP functionality is similar to FTP,but since FTP uses a different protocol,you cannot use FTP client to talk to an SFTP server.

To use SFTP capabilities,you can try out either graphical SFTP client or either at the command line.

At command line -[In Unix or Mac OS environment]

  • Start a SFTP session by 'sftp username@hostname'
  • Then enter the password when prompted.
  • Then with using sftp commands you can try-out file operations.[To get SFTP commands type 'help']
When you are using command line to SFTP operations you'll mostly remember about SCP protocol usage.But compared to SCP,there are advantages in SFTP protocol.
  • SCP provides only file-transfering,but SFTP provides more operations on remote files.
  • SFTP client has extra capabilities compared to a SCP client as directory listing,remote file removal and resume interrupted transfers.
Graphical SFTP Clients

There are several SFTP clients that can be try-out and could be found from internet.But note that the FTP only clients coudn't be use to access to SFTP.I tried out two such graphical SFTP clients,which are able to get freely.

1. WinSCP- This is an free client support all SFTP,SCP and FTP.It's main function is file transfering between a local and a remote computer.Adding to that it provides scripting support and file manager functionality.You can find more info on [1].

2.gFTP-This is a free multithreaded file transfer client for *NIX based machines.You can install the client from ubuntu software center.For more info refer [2].

Convert an InputStream to XML

For that we can use DocumentBuilder class in java. By using the method parse(InputStream) ; A new DOM Document object will return. InputStream input; DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder parser = factory.newDocumentBuilder(); Document dc= parser.parse(input); In the above code segment,by using the created Document object,the corresponding XML file for the inputStream can be accessed.

Concat two xml values with XSLT

The use-case described in this blog-post,is there's an WSO2 ESB node setup to proxy an incoming message to a particular back-end endpoint.  Before delivering the message to the back-end endpoint,from the ESB node itself,this incoming message need to processed and change its inside xml payload format. For eg: Below is the incoming message <?xml version="1.0" encoding="UTF-8"?> <CinemaHall name="liberty"> <OwnerData> <Name>John Smith</Name> <openedDate>12/12/80</openedDate> <quality>good</quality> </OwnerData> <CinemaHallData> <rows>100</rows> <seats> <seat>50</seat> <seat>60</seat> </seats> </CinemaHallData> </CinemaHall> This message need to be changed as  below; <?xml version="1.0" encoding="UTF-8"?> <CinemaHall name="liberty"...

Passing end-user details from client to real backend endpoint via JWT token

In real-world business system,WSO2 API Manager useful on exposing company APIs, in a secured and controlled manner with the features provided by APIManager as; OAuth support [To secure API invocations] Throttling support [To control API invocations] Monitoring support [To track API usage] More technically what happening is when a user sends a particular API request,it will goes to WSO2 APIManager node and from there,the request will route to the real implemented back-end endpoint of the particular API and get back the response and returned it to the API invoked user. There can be a use-case,that this back-end endpoint may expect the details of API invoked user as to pass those details to some internal company usage  as; Additional authentication/authorization Track usage data from an internal system. So how to support above requirement from WSO2 AM. There comes the use of JSON Web Token[JWT] implementation done inside WSO2 AM. JWT is a means of representing claims to...
