Configure sftp sites to be able to get/put sftp files.

Configure

grouper.properties

##################################
## SFTP sites
## the "configId" will be the identifier used in code to pull up that site, dont put special chars in it
## you shouldnt have the same host and username in two different configIds since its essentially the primary key
## e.g. if you sftp server is "depot.school.edu", the configId could be "depot"
##################################


general config

# SFTP needs to use some files to connect.  Keep this in a dir that only the tomcat user can read
# otherwise it will use the tmp dir configured in grouper.properties.
# {valueType: "string"}
grouperSftpBaseDirName = 

config per site

# host: e.g. some.server.com

# you can encrypt the private key to connect with.  if its more than 4k encrypted, then take it in chunks and they will be concatenated
# and use _0, _1, _2, etc.  Note, replace newlines with $newline$ so it fits in a textfield
# {valueType: "password", sensitive: true, regex: "^grouperSftp\\.site\\.[a-zA-Z0-9._-]+\\.secret\\.privateKey_[0-9]$"}

Using the API

You can make individual calls or use a callback to do multiple calls more efficiently

Individual calls

GrouperSftp.sendFile("depot", new File("d:/temp/temp/MyFile.csv"), "/data01/isc/bplogix/MyFile.csv");

System.out.println(GrouperUtil.toStringForLog(GrouperSftp.listFiles("depot", "/data01/isc/bplogix/")));

System.out.println(GrouperSftp.existsFile("depot", "/data01/isc/bplogix/MyFile.csv"));

GrouperSftp.copyFile("depot", "/data01/isc/bplogix/MyFile.csv", "/data01/isc/bplogix/MyFile2.csv");

GrouperSftp.moveFile("depot", "/data01/isc/bplogix/MyFile.csv", "/data01/isc/bplogix/MyFile3.csv");

GrouperSftp.receiveFile("depot", "/data01/isc/bplogix/MyFile3.csv", new File("d:/temp/temp/MyFile2.csv"));

GrouperSftp.deleteFile("depot", "/data01/isc/bplogix/MyFile3.csv");




Multiple calls in callback

    GrouperSftp.callback("depot", new GrouperSftpCallback() {
      
      public Object callback(GrouperSftpSession grouperSftpSession) {
        grouperSftpSession.sendFile(new File("d:/temp/temp/PennUsers.csv"), "/data01/isc/bplogix/PennUsers.csv");
        grouperSftpSession.deleteFile("/data01/isc/bplogix/whatever.txt");
        return null;
      }
    });
