Gateway for NFS

February 22nd, 2012 No comments

Gateway for the NFS Sharing application is used to make the gateway shares. Begin Gateway for the NFS Shares application from Services for the UNIX program group, and command line. So, from here you will make the gateway share, which is available to all the Windows clients like it were the local share from a gateway computer. Every gateway share makes use of the drive letter from gateway computer, and limiting number of the shares to maximum number of the free drive letters that are available on a gateway computer.

 

From command line, the Gateway for the NFS shares are all managed making use of gwshare.exe utility. For coming details on making use of the gwshare, see the type:

 

gwshare /?

 

Tip Gateway for the NFS shares are all limited by number of the available drive letters at a gateway server. However, in case, you need any additional shares beyond the number, you may use one or more gateway server for giving additional shares to distribute a load.

 

Server for the PCNFS

Server for the PCNFS gives PCNFSD support and you may enter all necessary information to make the users as well as groups using Services for the UNIX MMC, which may allow Server for the PCNFS to handle authentication of the NFS file resources for NFS clients.

 

Simplify the Network Administration

Services for the UNIX give some important tools to improve & simplify administration of the network and these tools will include:

 

  1. ActivePerl – Allows the existing & new scripts to take benefit of Windows Management Interface to automate the network administration tasks.

 

  1. Telnet Server – Allows character & script based administration of the Windows2000 & Windows NT servers from various clients.

 

  1. Telnet Client – Allows character & script based access or administration across various platforms.

 

  1. Microsoft Management Console Snapin –Allows the consistent & central management for all the SFU functionality.

 

 

Telnet Client

The SFU gives the character telnet client, which is faster & robust than default graphical client given by the Windows NT. In the Windows 2000, the Microsoft integrated the telnet client, and replacing old version. Telnet client that is supplied with the SFU goes totally beyond one in the Windows2000 for supporting both and console mode and stream mode, and gives for logging as well as additional configuration settings and commands, which make that more robust in the mixed environment.

NFS Client Vulnerabilities

February 22nd, 2012 No comments

NFS clients might be in the danger from the NFS servers. For instance, the NFS mounted file system might have the setuid programs; the users on client will use these programs to get a root. The device entries on the NFS mounted partition are been considered to apply for the client’s devices, and not server’s devices. Someone with the account on NFS client & root permission on the NFS server will make use of this for getting the unlimited, read write access to data on a client.

 

Few NFS clients give the choices to mount that is used to disable the devices as well as setuid or setgid on the mounted file systems. In case, mount is not accessible to the users other than the root, or in case, it uses the options for the users other than the root, this can protect a client from server. In case, all these options are not accessible, even though just root will mount the file systems, you must consider mounting the NFS file system being equivalent in granting a server machine access to client.

 

The NFS clients might as well be vulnerable to the less obvious types of attack from the NFS servers. Mounting the file system is the privileged operation, thus NFS clients run as the root. The hostile server can exploit the buffer overflow errors in NFS client, and causing that to run the arbitrary programs. Generally, it is not transparent to user (that interferes with an ability to utilize whatever file system, which client tries to get), and it needs the attacker with high level of the control over server machine. In the traditional fixed server environments, it is not the major threat. Alternatively, use of the automounters that are been discussed in the later section, will make that the effective attack.

 

File Locking with the NFS

File locking enables one process to stop other processes to access the file in any specific ways. Often it is used to keep the multiple processes to write overlapping changes to the file, however it will as well get used for some other reasons (for example, it is advisable to keep some other processes from reading the file when it is changed). The NFS gives the voluntary file mechanism. So, by default, there are not any locks that are associated with the file, any process will do anything with that.

Network File System (NFS)

February 20th, 2012 No comments

NFS protocol is made to allow the systems to have access files over the network on the remote system, conveniently like files were attached directly on disks. NFS protocol was made to get stateless for server implementation robustness and simplicity.

The stateless protocol is the one where every transaction is been handled separately; server will not have to keep the information regarding what clients already have done earlier. To be stateless allows the NFS server to reboot whereas clients are making the requests and, when it returns to the service, carry on serving files to the clients like nothing had ever happened.

 

This might appear like the fairly easy concept, however it is quite difficult in making the protocol stateless while it deals with the file access. Many important features of file systems are based inherently on the state. For example, to maintain the file locking needs keeping the track of what procedure has locked a file. The design decision had the major impact on the security as well as proliferation of the system administrator jokes that are based on kernel message the “NFS server not at all responding”.

 

Machines are NFS servers (and exporting the disks for an access by some other machines), the NFS clients (and accessing the disks exported by the NFS servers), and both. Almost each Unix implementation makes use of NFS as a primary method to share the files, or NFS client applications are accessible for other famous operating systems. (The NFS server applications for the nonUnix machines are rare.)

 

And 2 versions of the NFS are at present in the widespread use. The NFS version 2 is a protocol people are generally referring to while they mention this term NFS. It is generally run over the UDP (though specification allows any use of the TCP, most of the implementations don’t implement that). NFS version 3, often written as the NFSv3, is the newer version with many improvements, which includes support for the larger files, and each implementation allows to be run at TCP and UDP. From the safety standpoint, there is very little to distinguish between 2 versions, thus we make use of term NFS for applying to both the versions unless noted. NFS protocol is the straightforward RPC protocol, all the implementations and the versions make use of fixed port number (generally port 2049).

Open Source Financial Applications on Linux – More Advanced

February 19th, 2012 No comments

Most of the computer users are becoming more familiar with the Windows based application or programs for their personal and commercial financial management. However, they are reminding one thing that the Linux users can manger their financial works faster and easily than Windows based users.

It is also the best substitute and capable to perform any sorts of complicated task easily through few clicks. Due to faster processing, Linux has mentioned as the best open source financial application than others. Linux is also providing numbers of financial related software in free. This software is also adjusted in different interface, so you can’t get this sort of alternative for your financial task.     The system requirements are low, BasicBooks costs around $20 every CPU as well as are available in the binary package form (for Fedora, RedHat, Ubuntu, SuSe, Vector, and many more) that includes user reference manual.

The features also include the international support, simple data entry, outstanding GUI, backup or restore, error correction, multi-company support, online help, mailing labels, data import, chart of accounts, user-level security, journal entries, statement printing, sales orders, customer quotes, multiple taxes, invoicing, price management, discounting, cash reconciliation and accounts receivable. You may also download the evaluation version and free single PC edition is as well available.

SQL-Ledger

It is one of oldest Linux accounting or ERP systems. The SQL Ledger is the double entry accounting, which has the amazing list of the features, like accounts receivable, voucher system, accounts payable, inventory control, general ledger, time cards, billing, check printing, POS, taxes, purchase/sales orders, audit control, multi-user/company, templates, SQL server backend, chart of accounts, customers, vendors, as well as financial statements. The SQL Ledger is considered as “best” for the Linux accounting. It is one more package, which is more than the financial tool. Somebody looking for the single user financial program may want to look somewhere else. But in case, you need the small to midsize of financial solution, then you must look here first.

Why Services for UNIX?

February 18th, 2012 No comments

With growing adoption of Microsoft Windows NT operating system in the established UNIX environments, need for 2 platforms for interoperating has increased. The services for the UNIX version 3 gives the set of some additional features to the WindowsNT and Windows2000 or XP, which allow for the greater interoperability with the existing UNIX systems in an enterprise. Interix technology included with the Services for the UNIX version 3 highly increases an ability to migrate the applications written originally for the UNIX or Linux as well as retarget them for running on the Windows.

 

The services for the UNIX version gives you complete range of the supported as well as fully integrated components and complete SDK, which supports more than 1,900 UNIX API’s, and making it simple for the customers to integrate the Windows NT 4 and Windows 2000 or XP operating systems in the existing UNIX environments. The services for UNIX 3.0 gives:

 

  1. Interoperability components, which leverage the existing UNIX network sources & expertise within the organizations
  2. Manageability components, which allow the organizations to simplify the network administration & account management over both the platforms
  3. Development components, which give the full featured development, which leverages the existing UNIX developmental
  4. The migration components that allow the organizations to retarget the existing UNIX applications as well as scripts to the Windows, giving the robust & resource sparing home for the legacy UNIX applications when giving the clear path to features of .NET

 

Leverage Existing the UNIX Network Resources

The services for the UNIX provides you 4 important tools to let you leverage the existing UNIX resources for the Windows clients as well as servers whereas letting the UNIX clients to use resources of the Windows servers. These tools are:

 

  • Client for the NFS – allows Windows clients to have an access to resources of the NFS servers on network.
  • Server for the NFS – Allows NFS clients on network to access Windows Server resources via NFS. NFS Service is fully cluster aware, and supporting active or active clusters.
  • Gateway for the NFS – Allows Windows client to have an access NFS resources of network without additional components on client.
  • Server for the PCNFS – Allows Windows NT or 2000 or XP to act like PCNFSD servers, and giving user authentication for the file access to the NFS servers
