@yegor256 please, pay attention to this issue
Shell shell = new SSH(serverIP, 22, userName, password);
String stdout = new Shell.Plain(shell).exec("echo 'Hello, world!'");
The password is a private key:

When I use a URL which define the private key file. the same error.
URL keyUrl = new URL("file:/u/bwang018/.ssh/privateKey");
shell = new SSH(serverIP,22,userName,keyUrl);
String stdout = new Shell.Plain(shell).exec("ifconfig");
If I only use the following dependency which is used by the jcabi project, there is no connection error.
<dependency>
<groupId>com.jcraft</groupId>
<artifactId>jsch</artifactId>
<version>0.1.54</version>
</dependency>
The test code:
JSch jsch = new JSch();
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
jsch.addIdentity( the private key file path);
session=jsch.getSession(userName, host, port);
session.setConfig(config);
session.connect();
wdquan1985 - As per your above comment The test code:
JSch jsch = new JSch(); Properties config = new Properties(); config.put("StrictHostKeyChecking", "no"); jsch.addIdentity( the private key file path); session=jsch.getSession(userName, host, port); session.setConfig(config); session.connect();
For JDK_1.8_131 it runs swiftly but when I use version above > JDK_1.8_131 I get this error Anyone else facing the similar issue.
I even tried updating the /etc/ssh/sshd_config and restarted on the linux machine I want to access but I am still getting the
com.jcraft.jsch.JSchException: Algorithm negotiation fail
at com.jcraft.jsch.Session.receive_kexinit(Session.java:590)
Can anyone help on this ? please
@wdquan1985 I don't know what's going on. I think we should report it to jSch and see what they say.
@vlohana @yegor256 ,my java version is: C:\windows\system32>java -version java version "1.8.0_92" Java(TM) SE Runtime Environment (build 1.8.0_92-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)
same error as @vlohana, anyone have insights

My Issue got resolved as I did following to resolve

When I execute the following code, there are a Algorithm negotiation fail exception.
Shell shell = new SSH(serverIP, 22, userName, password);
String stdout = new Shell.Plain(shell).exec("echo 'Hello, world!'");
