Like any other industry with a high net worth, the financial services industry is tightly regulated to help curb illicit behavior and manipulation. Read this Term or oversight, which underlines the frailties in the patchwork of global regulation that continues to incentivise regulatory arbitrage.

Regulators can do very little aside from making public warnings, as many binary options websites and the firms operating them are based around the globe in territories that are not subject to rules or regulations. The exchange of currencies can be done over a physical counter, such as at a Bureau de Change, or over the internet via broker platforms, where currency speculation takes place, known as forex trading.

With regards to freely floating currencies, this is determined by supply and demand, such as imports and exports, and currency traders, such as banks and hedge funds. Emphasis on Retail Trading for ForexTrading the forex market for the purpose of financial gain was once the exclusive realm of financial institutions. All one needs is a computer, an internet connection, and an account with a forex broker.

Of course, before one starts to trade currencies, a certain level of knowledge and practice is essential. Once can gain some practice using demonstration accounts, i. place trades using demo money, before moving on to some real trading after attaining confidence. The main two fields of trading are known as technical analysis and fundamental analysis. Read this Term and binary options providers, each of which had failed to comply with Belgian regulation.

At the same time, a dozen Cypriot brokers were reportedly being closed down backed by a number of client complaints. In other words, when times are tough for brokers, applying for regulatory licenses may not be cost effective if clients are happy to open accounts regardless of whether regulation is present. The returned object is a CASTable object. CASTable objects are essentially client-side views of the table of data in the CAS server. You can interact with them using CAS actions as well as many of the pandas.

DataFrame methods and attributes. The pandas. DataFrame API is mirrored as much as possible, the only difference is that behind-the-scenes the real work is being done by CAS. In addition, you can also call the summary action directly on the CASTable object. Again, the output is a CASResults object a subclass of a Python dictionary , so we can pull off the keys we want there is only one in this case. DataFrame , you can do all of the standard DataFrame operations on it.

While CAS comes with a few pre-loaded action sets, you will likely want to load action sets with other capabilities such as percentiles, Data step, SQL, or even machine learning.

Once you load an action set, its actions will be automatically added as methods to the CAS connection and any CASTable objects associated with that connection. Note that the percentile action set has an action called percentile in it. you can call the action either as tbl. percentile or tbl. As we mentioned previously, CASTable objects implement many of the pandas. DataFrame methods and properties. This means that you can use the familiar pandas. DataFrame API, but use it on data that is far too large for pandas to handle.

Here are a few simple examples. For more information about CASTable , see the API Reference. To get around this issue, the CAS class supports authinfo files. Authinfo files are a a file used to store username and password information for specified hostname and port. They are protected by file permissions so that only you can read them. This allows you to set and protect your passwords in one place and have them used by all of your programs. machine is a synonym for host , login and account are synonyms for user , and protocol is a synonym for port.

You can specify as many of the host lines as possible. The port field is optional. If it is left off, all ports will use the same password. Hostnames much match the hostname used in the CAS constructor exactly. It does not do any DNS expanding of the names. By default, the authinfo files are looked for in your home directory under the name.

You can also use the name. netrc which is the name of an older specification that authinfo was based on. The permissions on the file must be readable and writable by the owner only. This is done with the following command:. SWAT 1.

There are many and varied opinions regarding the usefulness or otherwise of SWAT. No matter how hard one tries to produce the perfect configuration tool it remains an object of personal taste. SWAT is a tool that will allow web based configuration of samba.

It has a wizard that may help to get samba configured quickly, it has context sensitive help on each smb. conf parameter, it provides for monitoring of current state of connection information, and it allows network wide MS Windows network password management.

There are network administrators who believe that it is a good idea to write systems documentation inside configuration files, for them SWAT will aways be a nasty tool. SWAT does not store the configuration file in any intermediate form, rather, it stores only the parameter settings, so when SWAT writes the smb. conf file to disk it will write only those parameters that are at other than the default settings. The result is that all comments will be lost from the smb.

conf file. Additionally, the parameters will be written back in internal ordering. So before using SWAT please be warned - SWAT will completely replace your smb. conf with a fully optimised file that has been stripped of all comments you might have placed there and only non-default settings will be written to the file. SWAT should be installed to run via the network super daemon. The nature and location of the network super-daemon varies with the operating system implementation.

d or similar. In addition to the above SWAT will use a directory access point from which it will load it's help files as well as other control information. Access to SWAT will prompt for a logon. If you log onto SWAT as any non-root user the only permission allowed is to view certain aspects of configuration as well as access to the password change facility. The buttons that will be exposed to the non-root user are: HOME , STATUS , VIEW , PASSWORD. The only page that allows change capability in this case is PASSWORD.

So long as you log onto SWAT as the user root you should obtain full change and commit ability. The buttons that will be exposed includes: HOME , GLOBALS , SHARES , PRINTERS , WIZARD , STATUS , VIEW , PASSWORD.

Lots of people have asked about how to setup SWAT with SSL to allow for secure remote administration of Samba. Here is a method that works, courtesy of Markus Krieger.

The SWAT title page provides access to the latest Samba documentation. The manual page for each samba component is accessible from this page as are the Samba-HOWTO-Collection this document as well as the O'Reilly book "Using Samba". Administrators who wish to validate their samba configuration may obtain useful information from the man pages for the diagnostic utilities.

These are available from the SWAT home page also. SWAT can be configured to run in demo mode. This is NOT recommended as it runs SWAT without authentication and with full administrative ability. ie: Allows changes to smb. conf as well as general operation with root privileges. The option that creates this ability is the -a flag to swat. Do not use this in any production environment. The Globals button will expose a page that allows configuration of the global parameters in smb.

There are three levels of exposure of the parameters:. Advanced - exposes configuration options needed in more complex environments. Developer - exposes configuration options that only the brave will want to tamper with. To switch to other than Basic editing ability click on either the Advanced or the Developer dial, then click the Commit Changes button.

After making any changes to configuration parameters make sure that you click on the Commit Changes button before moving to another area otherwise your changes will be immediately lost.

SWAT has context sensitive help. To find out what each parameter is for simply click the Help link to the left of the configuration parameter.

To affect a currently configured share, simply click on the pull down button between the Choose Share and the Delete Share buttons, select the share you wish to operate on, then to edit the settings click on the Choose Share button, to delete the share simply press the Delete Share button.

To create a new share, next to the button labelled Create Share enter into the text field the name of the share to be created, then click on the Create Share button. To affect a currently configured printer, simply click on the pull down button between the Choose Printer and the Delete Printer buttons, select the printer you wish to operate on, then to edit the settings click on the Choose Printer button, to delete the share simply press the Delete Printer button.

To create a new printer, next to the button labelled Create Printer enter into the text field the name of the share to be created, then click on the Create Printer button. The purpose if the SWAT Wizard is to help the Microsoft knowledgeable network administrator to configure Samba with a minimum of effort.

The Wizard page provides a tool for rewriting the smb. conf file in fully optimised format. This will also happen if you press the commit button. The two differ in the the rewrite button ignores any changes that may have been made, while the Commit button causes all changes to be affected. The Edit button permits the editing setting of the minimal set of options that may be necessary to create a working Samba server.

Finally, there are a limited set of options that will determine what type of server Samba will be configured for, whether it will be a WINS server, participate as a WINS client, or operate with no WINS support.

By clicking on one button you can elect to expose or not user home directories. The status page serves a limited purpose. Firstly, it allows control of the samba daemons. The key daemons that create the samba server environment are: smbd , nmbd , winbindd.

The daemons may be controlled individually or as a total group. Additionally, you may set an automatic screen refresh timing. As MS Windows clients interact with Samba new smbd processes will be continually spawned. The auto-refresh facility will allow you to track the changing conditions with minimal effort. Lastly, the Status page may be used to terminate specific smbd client connections in order to free files that may be locked.

This page allows the administrator to view the optimised smb. conf file and, if you are particularly masochistic, will permit you also to see all possible global configuration parameters and their settings. The Password Change page is a popular tool. This tool allows the creation, deletion, deactivation and reactivation of MS Windows networking users on the local machine. Alternatively, you can use this tool to change a local password for a user account.

When logged in as a non-root account the user will have to provide the old password as well as the new password twice. When logged in as root only the new password is required. One popular use for this tool is to change user passwords across a range of remote MS Windows servers. Chapter SWAT - The Samba Web Administration Tool Prev Part IV. Migration and Updating Next.

Other issues that can occur with an Authinfo file include not having a hostname and port that matches the one used in the CAS constructor or simply having the incorrect possibly outdated password in the file.
