trying to use j2ssh to make a SSH2 Host based Connect
and getting error
com.sshtools.ssh.SshException: java.io.IOException at com.sshtools.ssh2.Ssh2HostbasedAuthentication.authenticate(Ssh2HostbasedAuthentication.java:112) at com.sshtools.ssh2.AuthenticationProtocol.authenticate(AuthenticationProtocol.java:206) at com.sshtools.ssh2.Ssh2Client.authenticate(Ssh2Client.java:340) at shh_test.main(shh_test.java:110)
Caused by: java.io.IOException: Failed to sign data! Could not sign data at com.sshtools.ssh.components.jce.Ssh2RsaPrivateCrtKey.sign(Ssh2RsaPrivateCrtKey.java:134) at com.sshtools.ssh2.Ssh2HostbasedAuthentication.authenticate(Ssh2HostbasedAuthentication.java:99)
i basically copied the example code from SSH2HostbasedConnect.java with small modifications such as hard-coded user name and host name
error happened at step
SshKeyPair pair;
if (pkfile.isPassphraseProtected()) {
System.out.print("Passphrase: ");
pair = pkfile.toKeyPair(reader.readLine());
} else
pair = pkfile.toKeyPair(null);
pk.setPrivateKey(pair.getPrivateKey());
pk.setPublicKey(pair.getPublicKey());
} while (ssh.authenticate(pk) != SshAuthentication.COMPLETE
&& ssh.isConnected());
I know for sure that my private key is working and I used it in tactia; and it had status - opened
what can cause it ?
I ran into a NPE in Ssh2Client.toString() when I enabled logging, set an own logger with LoggerFactory.setInstance(...) and connected to a SSH server.
The NPE happened at the first two log entries where the source is a Ssh2Client.
The first log entry reads "Connecting @:22".
The second log entry reads "Remote identification is SSH-2.0-OpenSSH_7.2".
At this point the Ssh2Client's field "transport" is null which causes the NPE in toString().
The 6th line in the method "run" in the class "com.sshtools.net.ForwardingClient.SocketListener" is final Socket socket = server.accept();
. The variable "server" can be null at this point which results in a NullPointerException. I recommend to change this code to ServerSocket server = this.server; if (server == null) {break;} final Socket socket = server.accept();
.
I'm sorry I can't provide you a code snippet to reproduce this exception (because I can't reproduce it myself).
Hi,
We are using j2ssh maverick version-1.5.5 , but while connecting to remote linux server we are getting the following SshException: EOF received from remote side in stacktrace:

Is there any method available for the following scenario?
Connect to SFTP Server through J2SSH Maverick implementation and upload some files.
Next time we need to upload one file. It should use the existing session and upload the file.
The session created in first step should maintain for the particular time. The next upload files should just re-use the session. If there is no upload in the particular period, the session will be closed. The next upload should connect, authenticate and reuse the session.
I am trying to connect to a SFTP server via SOCK5 proxy from a custom SFTP client( Java) using the maverick library. Works fine.
But when I configure the proxy server to use no authentication, I get the following error.
java.io.IOException: Invalid response from SOCKS5 server (72) localhost:1080
The socks5 proxy server used is CCproxy.
This is my code.
`SshClient ssh = null;
SshClient forwardedConnection = null;
/**
* Create an SshConnector instance
*/
SshConnector con = SshConnector.getInstance();
Ssh2Context context = (Ssh2Context) con.getContext(SshConnector.SSH2);
setupContext(context);
context.setHostKeyVerification(new ConsoleKnownHostsKeyVerification());
SocketTransport t = new SocketTransport(hostname, port);
t.setTcpNoDelay(true);
//System.out.println("t.isConnected() ->" + t.isConnected());
ssh = con.connect(t, username, true);
PasswordAuthentication pwd = new PasswordAuthentication();
pwd.setPassword(password);
ssh.authenticate(pwd);
if (ssh.isAuthenticated()) {
System.out.println("authenticated");
// Connect via socks5 proxy
SshTransport spt = SocksProxyTransport.connectViaSocks5Proxy(hostname, port, proxyServerHost, proxyServerPort, proxyServerUsername,proxyServerPassword);
//SshTransport spt = HttpProxyTransport.connectViaProxy(hostname, port, proxyServerHost, proxyServerPort, proxyServerUsername, proxyServerPassword, "Maverick");
forwardedConnection = con.connect(spt, username);
PasswordAuthentication pwd2 = new PasswordAuthentication();
pwd2.setPassword(password);
forwardedConnection.authenticate(pwd2);
}
return forwardedConnection;
}`

Hello,
Greetings !!.
I am facing issue to connect to remote SSH server with your latest version 1.5.4 and previously With version 1.5.3 my code is working well but when I updated version of to 1.5.4 it started to give me error
Code Snippet:
SshConnector con = SshConnector.createInstance();
con.getContext().setHostKeyVerification(new ConsoleKnownHostsKeyVerification());
SocketTransport sc = new SocketTransport("192.168.2.19", 22);
SshClient ssh = con.connect(sc, "pratap");
I am Using below Maven Dependency.

I've run into some issues recently trying to move roughly 200 files totaling about 27G over SFTP. I don't really expect the performance to match up to the native utilities, but for sake of completeness, in 100 tests of files ranging from 2MB to 2GB, the the discrepancy between the linux sftp
command tool and the j2ssh-maverick test class below is about 10x on put
operations and well over 80x on get
operations. In the tests, both servers are reading and writing to SSD with 8GB of dedicated memory and 2 dedicated CPU. I ran the same experiment over a GigE and 40G network, both in house, with little to no load on them.
My first question is how on earth can read and write performance differ so dramatically in the opposite direction? I've tried changing the SFTPClient blockSize, bufferSize, and the tcp socket preferences, but anything less than loading the entire file into memory causes put
to slow down and get
to crawl.
Second, we purchased a license to the Maverick Legacy Client a few years back and, because we open sourced our project, switched over to this library. None of the above behavior occurs in the commercial product, despite the current j2ssh-maverick library being a fork of the commercial library. Is the open source library intentionally throttled in some way? That would explain the dramatic increase in failure rates we've seen since switching from the commercial version.
Hey, amazing library! I'm having trouble with RSA authentication though. I have tried two different RSA keys, both generated by the PuTTYGen tool.
The error I get when using the rsa.ppk file is as follows:
java.io.IOException: The PuTTY key could not be read! aes256-cbc is not supported [Unknown cause]
at com.sshtools.publickey.PuTTYPrivateKeyFile.toKeyPair(PuTTYPrivateKeyFile.java:335)
Additionally (I don't know if this is related), the error I get when using the rsa file generated by PuTTYGen's OpenSSH Converter is as follows: (It's very vague.. I don't even know what the problem is)
com.sshtools.ssh.SshIOException
at com.sshtools.publickey.PEMReader.decryptPayload(PEMReader.java:206)
at com.sshtools.publickey.OpenSSHPrivateKeyFile.toKeyPair(OpenSSHPrivateKeyFile.java:86)
I am certain the supplied password is correct. Am I doing something wrong or is this something the library does not have support for?
Thanks
I need use ssh dynamic port forwarding, this library can do it?
I see it support "Dynamic SOCKS forwarding" feture in this page https://www.sshtools.com/en/products/j2ssh

Hi Team,
I am using maverick-legacy-client 1.7.14 licensed version.
in my code:
"SftpClient.copyRemoteDirectory(rfdir,lfdir,true,false,true,null);" throwing below exception, this is because the SftpClient.pwd() is returning incorrect path, the path is coming with a forward slash as a prefix (eg: /C:/Users/Username/).
This is happening only for windows for linux it is working fine.
appriciate your help, since we are licensed customers, please let me know where I can raise a support ticket.

Team,
I am using maverick-all 1.4.39 in my application to do SFTP with remote server. I logged in as root. My default dirctory is root.
Issue 1: When I tried to cd(".."), it return default dirctory. It shoud be return .
Issue2: I called cdup() method instead of cd(".."). It returned \ . Then I did ls(). It return nothing.
Why nothing worked for \ . I want to go to my home dirctory and get files under home. Please help me to achieve this.
Thank you very much in advance.
Thanks & Regards
Revathi Praba

Please tell me how to realize the establishment and disconnection of a method call. My attempts to realize such a lead to memory leaks.

Hi,
I use this library to transfer files sized up to some gigabytes. Sometimes, quite rare, such a transfer doesn't complete and runs forever without any progress. Whenever i do a thread dump in this situation, the output is always as follows:
"MessagePump_Thread-1388" #1399 prio=5 os_prio=0 tid=0x00007ff3f0bf1800 nid=0x2f6b runnable [0x00007ff3d623d000]

A comparisson of the source and target file in this situation shows:
Somewhere in the middle of the target file, a block sized by a multiple of 4k is missing. I observed the following blocksizes: 4k, 8k, 32k. After that block, the content again matches. The target file is always a bit shorter, but not in the same way as the missing block. What i often observe: if a 32k block is missing in the middle of the file, the file is around 55k smaller. The final content of the target file does not match the final content of the source. Maybe this is due to some buffered data not yet written by the sshd?
My test file is about 260MB: $ seq -w 30000000> testfile
Using testfiles of size ~3MB or ~30MB i was not able to reproduce this problem. I need to transfer the file repeatedly for several hours to run into the problem.
Currently i was able to reproduce this problem with the following target configurations:
cygwin, OpenSSH_7.2p2, OpenSSL 1.0.2g 1 Mar 2016
cygwin, OpenSSH_7.6p1, OpenSSL 1.0.2n 7 Dec 2017
cygwin, OpenSSH_6.6.1p1, OpenSSL 1.0.1i 6 Aug 2014
On the other hand, i was not able to reproduce it on
linux, OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.8, OpenSSL 1.0.1f 6 Jan 2014
linux, OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
While it currently might looking like a cygwin problem, couldn't it be a timing/concurrency issue which only occurs due to the limited performance of cygwin?
Please let me know if (and how) i can provide more information.
This is the code i use to perform the scp put:
public void scp(String local, String remote, String hostname, int port, String username, String keyfile, String passphrase) throws IOException {
try {
SshConnector con = SshConnector.createInstance();
con.getContext().setHostKeyVerification(
new DisabledKnownHostsVerification());
con.getContext().setPreferredPublicKey(Ssh2Context.PUBLIC_KEY_SSHRSA);
try (SocketTransport t = new SocketTransport(hostname, port)) {
t.setTcpNoDelay(true);
Ssh2Client ssh2 = (Ssh2Client) con.connect(t, username, true);
try {
PublicKeyAuthentication pk = new PublicKeyAuthentication();
try (FileInputStream fis = new FileInputStream(new File(System.getProperty("user.home") + File.separatorChar + ".ssh" + File.separatorChar + keyfile))) {
SshPrivateKeyFile pkfile = SshPrivateKeyFileFactory
.parse(fis);
SshKeyPair pair;
try {
if (pkfile.isPassphraseProtected()) {
if (passphrase == null) {
throw new RuntimeException("private key is passphrase protected, but passphrase is missing");
}
pair = pkfile.toKeyPair(passphrase);
} else {
pair = pkfile.toKeyPair(null);
}
} catch (InvalidPassphraseException e) {
throw new RuntimeException("The causing exception may be due to a wrong passphrase", e);
}
pk.setPrivateKey(pair.getPrivateKey());
pk.setPublicKey(pair.getPublicKey());
}
if (ssh2.isConnected()) {
ssh2.authenticate(pk);
if (ssh2.isAuthenticated()) {
new ScpClient(ssh2).putFile(local, remote, false, null, false);
} else {
throw new RuntimeException("Authentication failed!");
}
} else {
throw new RuntimeException("Connection failed!");
}
} finally {
ssh2.disconnect();
}
}
} catch (SshException | ChannelOpenException e) {
if (e.getCause() instanceof IOException) {
throw (IOException) e.getCause();
}
throw new RuntimeException(e.getMessage(), e);
}
}
