Hi All,
The problem is resolved now. It was because my client was sending an
extra authentication request. Client can't be changed. so i have overridden
the SessionFactory to resolve the issue, when the extra user auth comes
sshd.setSessionFactory(new IgnoreExtraAuthSessionFactory());
public class IgnoreExtraAuthSessionFactory extends SessionFactory {
protected IgnoreExtraAuthSessionFactory() {}
protected AbstractSession createSession(IoSession ioSession)
throws Exception
{
return new IgnoreExtraAuthServerSession(this.server, ioSession);
}
}
public class IgnoreExtraAuthServerSession extends ServerSession {
IgnoreExtraAuthServerSession(ServerFactoryManager server, IoSession
ioSession)
throws Exception
{
super(server, ioSession);
}
protected void doHandleMessage(Buffer buffer) throws Exception {
byte cmd = buffer.array()[buffer.rpos()];
if(cmd == SshConstants.SSH_MSG_USERAUTH_REQUEST && isAuthenticated() ==true
){
return;
}
super.doHandleMessage(buffer);
}
}
Regards,
Sendilraj P
