OPRA

The OPRA project investigates high frequency trading with options. It's a joint project of the universities of Vienna and Lancaster. New project members have to be commissioned by Prof. Hautsch or Prof. Nolte. The project server opra.vdc.ac has been set up as part of the Vienna Data Center (vdc) Academic (ac).

1 Structure

/home is the directory in which all project members got their home-directory (e.g /home/some_user)

/home/OPRA contains all data.

/home/OPRA/raw contains the raw data.

/home/OPRA/sql contains the sql data.

all project members are local users belonging to the opra group and-or the sql group. Everybody can read all OPRA data, only members of the sql group can populate the sql directory.

2 Access

Access the data via ssh (sftp, scp, or tunnel rsync through it), and ftpes (i.e. explicit ftp), either from the command line (shell-script) or from a GUI like FileZilla.

filling in e.g. FileZilla

1. sftp (ssh) protocol -> | Server: sftp://opra.vdc.ac | User: ivana | Password: top_secret
2. ftpes protocol -> | Server: ftpes://opra.vdc.ac | User: hans | Password: i_wont_tell

2.1 Security

Man in the middle attack is rather unlikely, you can ignore that. Otherwise check at the first ssh-connection, or when importing the self-signed certificate into e.g. FileZilla.
