|I am testing Jsch 0.1.35 on the command line and the test programs
|generates a GSSException message everytime, even though the connection
|is successful. For example,
|GSSException: No valid credentials provided (Mechanism level: Failed to
|find any Kerberos Ticket)
| at
sun.security.jgss.krb5.Krb5InitCredential.getInstance(Krb5InitCredential.java:133)
...
| at
sun.security.jgss.GSSContextImpl.initSecContext(GSSContextImpl.java:158)
| at com.jcraft.jsch.jgss.GSSContextKrb5.init(Unknown Source)
| at com.jcraft.jsch.UserAuthGSSAPIWithMIC.start(Unknown Source)
| at com.jcraft.jsch.Session.connect(Unknown Source)
| at com.jcraft.jsch.Session.connect(Unknown Source)
I can not understand why GSSException is thrown from
GSSContextKrb5#init(byte[], int, int)
, which has been defined as follows,
public byte[] init(byte[] token, int s, int l) throws JSchException {
try{
return context.initSecContext(token, 0, l);
}
catch(GSSException ex){
throw new JSchException(ex.toString());
}
}
Are you really using the original source code?
|Another alternative is to put gssapi-with-mic at the back of that
|PreferredAuthentications option, or take it out completely. However, I
|tried generating the documentation using javadoc but there is no method
|that sets PreferredAuthentications. I looked into the source code and it
|appears that this is a configuration that is set in Jsch.java. There
|appears to be no way to set this class variable apart from changing the
|source code. Technically, that would be a change to the Jsch source as
|well.
Session session=jsch.getSession(user, host);
...
session.setConfig("PreferredAuthentications",
"publickey,keyboard-interactive,password");
session.connect();
