I am getting below error while trying to connect to one of the windows server from AWS cluster. Caused by: com.jcraft.jsch.JSchException: UnknownHostKey: x.y.com. DSA key fingerprint is "ac:ew:..... Note: I generated the RSA keys using PuTTYgen, but every time it tries to connect it gives issue with DSA fingerprint. I referred multiple SO links but unable to get the right solution. Finally I tried below approach based on one of the posts. Get the session first time with StrictHostKeyChecking as no . Once done, save the result to known hosts file on the AWS server so that next time it tries to

I want to display complete hierarchy of a directory at a remote location using JSch. The location has multiple folders and a folder may or may not have files. Code written by me (taken reference from SFTP Read all files in directory ): sftpChannel.cd(remotePath); Vector<String> files = sftpChannel.ls("*"); List<String> ret=new ArrayList<>(); for (int i = 0; i < files.size(); i++) { Object obj = files.elementAt(i); if (obj instanceof com.jcraft.jsch.ChannelSftp.LsEntry) { LsEntry entry = (LsEntry) obj; if (true && !entry.getAttrs().isDir()) { ret.add(entry.getFilename()+"file"); } if (true &&

I would like to upload a file from my local unix machine to a remote server that supports SFTP. I tried to implement using Ant script that used SCP task with sftp attribute set to true, but it didn't work, since it would always error out: com.jcraft.jsch.JSchException: 4: Received message is too long: 1416128878. If you can help me achieve that using shell script that should resolve the issue. Also will I have to install sftp or something on my local machine so that the script works? Any help here would be greatly appreciated. Cheers, Ashley Your Ant script works. It's the server that does not

I'm trying to execute a Unix command from Java. I'm using the JSch library. Here's my code: try{ Session session = new JSch().getSession("*****", "****", 22); session.setPassword("****"); java.util.Properties config = new java.util.Properties(); config.put("StrictHostKeyChecking", "no"); session.setConfig(config); session.connect(); Channel channel=session.openChannel("exec"); ((ChannelExec)channel).setCommand("pwd"); InputStream in=channel.getInputStream(); byte[] tmp=new byte[1024]; while(in.available()>0){ int i=in.read(tmp, 0, 1024); System.out.print(new String(tmp, 0, i)); } channel
