Linux System Accessing Isilon SMB

Hi Mark,

Here's a couple things I'd check first:

1) Depending on packages installed, it's usually possible to mount an smb share from the linux box.  Can you test this?

2) What credentials are being used by your jcifs application?  Are you connecting to the Isilon cluster through the correct SmartConnect Access Zone? 

Just to add for completeness how I compile and run this program:

root@yfvm-deb1:~/jcifs/jcifs-krb5-1.3.17# cat setcp
export CLASSPATH=~/jcifs/jcifs-krb5-1.3.17/jcifs-krb5-1.3.17.jar:.
root@yfvm-deb1:~/jcifs/jcifs-krb5-1.3.17# . setcp
root@yfvm-deb1:~/jcifs/jcifs-krb5-1.3.17#
root@yfvm-deb1:~/jcifs/jcifs-krb5-1.3.17# javac NetworkShareFileCopy.java
root@yfvm-deb1:~/jcifs/jcifs-krb5-1.3.17# java NetworkShareFileCopy
User: faubert:xxxxxxx
Path: smb://static.vm7027.yfisi.local/ifs_data_oplock/testFile.txt
Successful: true

And I did validate the file actually got created on the cluster!

yfvm-7027-2# pwd
/ifs/data/oplock
yfvm-7027-2# ls -latr testFile.txt
-rwx------ +  1 faubert  YFISI\clusteruse  29 Apr 25 09:34 testFile.txt
yfvm-7027-2#

I will test these out and let you know.

Thanks Yan - nicely done.

Interesting comparison on the # of lines of code needed for this technique versus doing a RESTful PUT of a given file.

I did a test with basic jcifs program and was able to create a file over SMB to a cluster that is joined to AD.

My environment:

OneFS (7.0.2.7):

Isilon OneFS yfvm-7027-2 v7.0.2.7 Isilon OneFS v7.0.2.7 B_7_0_2_263(RELEASE): 0x700025000700107:Thu Feb 27 12:40:26 PST 2014    root@fastbuild-05.west.isilon.com:/build/mnt/obj.RELEASE/build/mnt/src/sys/IQ.amd64.release amd64

Linux:

Sample code I used with jcifs-krb5-1.3.17.jar:

root@yfvm-deb1:~/jcifs/jcifs-krb5-1.3.17# cat NetworkShareFileCopy.java
import jcifs.smb.NtlmPasswordAuthentication;
import jcifs.smb.SmbFile;
import jcifs.smb.SmbFileOutputStream;


public class NetworkShareFileCopy {
    static final String DOMAIN = "YFISI";
    static final String USER_NAME = "my_domain_id";
    static final String PASSWORD = "my_domain_pass";
    //e.g. Assuming your network folder is: \\my.myserver.net\ifs_data_oplock\
    static final String NETWORK_FOLDER = "smb://static.vm7027.yfisi.local/ifs_data_oplock/";


    public static void main(String args[]) {
        String fileContent = "This is a test file some data";


        new NetworkShareFileCopy().copyFiles(fileContent, "testFile.txt");
    }


    public boolean copyFiles(String fileContent, String fileName) {
        boolean successful = false;
        try{
                String user = USER_NAME + ":" + PASSWORD;
                System.out.println("User: " + user);


                NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(DOMAIN, USER_NAME, PASSWORD);
                String path = NETWORK_FOLDER + fileName;
                System.out.println("Path: " +path);


                SmbFile sFile = new SmbFile(path, auth);
                SmbFileOutputStream sfos = new SmbFileOutputStream(sFile);
                sfos.write(fileContent.getBytes());


                successful = true;
                System.out.println("Successful: " + successful);
            } catch (Exception e) {
                successful = false;
                e.printStackTrace();
            }
        return successful;
    }
}

This is my 'python' equivalent of what the previous sample is doing but using the RAN API.

yfaubert@yfvm-deb1:~/ran$ cat create_file.py
import requests

ran_url = "https://yfvm-7027.yfisi.local:8080/namespace/ifs-data-ran"
filename = file_to_send = "file_to_send.dd"
authinfo = ('papiuser', 'papi_password')

if __name__ == "__main__":
    fullpath = ran_url + "/" + file_to_send
    param = {"overwrite": True}
    headers = {'content-type': 'binary/octet-stream', 'x-isi-ifs-target-type': 'object', 'x-isi-ifs-access-control': '0644'}

    with open(filename) as file:
        create_reply = requests.put(fullpath, data=file, verify=False, headers=headers, params=param, auth=authinfo)

    print "Create reply: " + str(create_reply.text)
