I am having some problem using j2ssh.I am getting below error.Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at com.sshtools.j2ssh.SshClient.(Unknown Source)
MY Code:
SshClient ssh = new SshClient();
//HostKeyVerification host = new IgnoreHostKeyVerification();
String hostname = “hostname”;
String username = “username”;
String password = “password”;
ssh.connect(hostname);
//ssh.connect(”firestar”, new ConsoleKnownHostsKeyVerification());
PasswordAuthenticationClient pwd = new PasswordAuthenticationClient();
pwd.setUsername(username);
pwd.setPassword(password);
int result = ssh.authenticate(pwd);

Please suggest

As mentioned above, it seems J2SSH does not work with SSH1 keys. I’m getting all kinds of errors like:

java.lang.NegativeArraySizeException

and

com.sshtools.j2ssh.transport.TransportProtocolException: The protocol version of the remote computer is not supported!

Does anyone know of other libraries that don’t have this problem? I’m going to have to find a solution this week. If I find one, I’ll post back to this blog.

Does anyone have an example of configuring and running the SshDaemon server that is part of the sshtools library? I would like to run it on a port other than 22.

JSch does NOT DEPEND ON SWING/AWT. Only the examples they provide do.

Hi,
I am using this sshtools sftp lib and I experience it keeps showing “waiting for new messages” inside the log files when I want to download file from SFTP Server. this error happens randomly so its difficult for me to find the caused. Is there any solution for this error ? or ways to avoid this kind of error

Thank you

Has anybody got past the file size problem, if you transfer a file over 80kb it’s seems to crash the transfer sometimes.

When I try this:
SshClient ssh = new SshClient();

My java class just dies. No exceptions, no messages, no fuss it just dies. Using jre 1.4.2_18

What can I possibly look into?

This is really helpful thanks for posting this.

Do you know if there is there a way to authenticate with a public and private key and can you set it to automatically accept host files and keys?
