Free nfs software for linux

FreeNAS 0.69b4 / 0.686.4 Stable gives a program which is to support FTP, NFS protocols, Software RAID(0,1,5) with a Full WEB configuration interface. It takes less than 16MB once installed on Compact Flash, hard drive or USB key.

Web Perl module contains a set of useful routines for many webworking purposes.

This module was primarily made for UNIX/Linux-Systems. Parts of it cannot be used on other systems. E.g. the procedures for file locking demand systems that can use symlinks. If you use the modul on systems where symlinks cannot be used, fatal errors may happen.

ABSTRACT

This perl module serves users with several useful routines for many purposes, like generating webpages, processing CGI scripts, working with XML datafiles and net-connections. It also uses own variants of routines, that was invented first in the famous libraries CGI.pm and cgi-lib.pl.

INSTALLATION

If you dont have sufficient privileges to install web.pm in the Perl library directory, you can put web.pm into some convenient spot, such as your home directory, or in cgi-bin itself and prefix all Perl scripts that call it with something along the lines of the following preamble:

use lib /home/myname/perl/lib;
use web;

NLock

This routine allows to set a filelock across NFS-boundaries. The common used perl-routine flock() fails at this point, so this routine is a useable alternative for bigger file-systems. It uses the modular functions link() and unlink() to mark a file locked. In addition to this, it also gives the locked file a counter: A file that is locked for more than $web::MAX_LOCKTIME seconds will be freed by the next process that calls NLock() on this file. A calling process gets either 0 or 1 as a return value, where 1 is returned if the file-locking was successful. 0 is returned only if the process waits for more than $web::MAX_WAITLOCK seconds or if symlink() fails.

Example 1:

$filename = "data.txt";
NLock($filename);
open(f1,"$filename");
# do something
close f1;
NUnlock($filename);

Example 2:

#!/local/bin/perl5
use web;

$stat= &NLock("jump.pl");
print "Lock: stat= $statn";
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
sleep 8;
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
$stat= &NUnlock("jump.pl");
print "Unlock: stat= $statn";
exit;

openQRM Plug-ins is a collection of community-supported plug-ins that enable openQRM to manage other enterprise and open source software.

openQRM is designed to deal with all sorts of failures automatically, thus preventing interrupts because of unexpected events.

Implementing openQRM greatly improves the reliability of the x86 data-center.

openQRM is an open source systems management platform which integrates with existing components in enterprise data centers to create scalable, highly available and customizable infrastructures.

openQRM is derived from a proven commercial product and distributed as an open source project through SourceForge, using a modified Mozilla Public License.

openQRMs architecture extends to and embraces other existing data center technologies through "plug-ins."The openQRM project team has created a number of plug-ins for broadly-used open source projects and proprietary solutions, and seeks to recruit community members to assist in additional plug-ins.

openQRM leverages the proven technologies of PXE and NFS along with storing images on central storage to effectively manage the data center.

The project team aims to set the standard in data center management by continuing to provide a "premiere" enterprise-grade project for automating IT infrastructure, and by embracing other technologies through increasing our offering of plug-ins.

OpenQRM.org is the best destination for our projects community to share ideas and innovations. Contributed by Qlusters, openQRM.org offers a range of support and information services to benefit all users of openQRM, including implementation advice, user forums and customer feedback.

GXemul is a machine emulator Im developing in my spare time.
GXemul project emulates processors and surrounding hardware components, in some cases well enough to allow unmodified "guest" operating systems to run inside the emulator as if they were running on a real machine.
MIPS:
- Several machine types are emulated well enough to run guest operating systems. NetBSD, OpenBSD, Linux, and even obscure things such as Ultrix and Sprite can run, to various degrees.
ARM:
- CATS is emulated well enough to run NetBSD and OpenBSD as guest OSes.
PowerPC:
- NetBSD/prep can run (experimental).
The emulator can be used for:
- experimenting with operating systems which you have not tried yet, or operating systems for hardware which you might not have access to,
- running guest operating systems for historical purposes, e.g. Ultrix or Sprite,
developing portable software, when you want yet another target platform to try to compile your software on (you can use GXemul to run a guest OS and compile your software inside that OS),
- development of new firmware or operating system code (but then you need to be aware of some limitations),
- educational purposes...
Enhancements:
- NetBSD/pmppc can now run in the emulator (with root on NFS).
- For ARM emulation (with NetBSD/cats, OpenBSD/cats, NetBSD/evbarm, or NetBSD/netwinder as the guest OS), the emulator does not use 100% of the hosts CPU if the guest OS is idle.

Solaris::MapDev Perl module contains a map between instance numbers and device names.

SYNOPSIS

use Solaris::MapDev qw(inst_to_dev dev_to_inst);
my $disk = inst_to_dev("sd0");
my $nfs = inst_to_dev("nfs123");
my $inst = dev_to_inst("c0t0d0s0");
mapdev_data_files(path_to_inst => "/copy/of/a/path_to_inst",
mnttab => "/copy/of/a/mnttab",
dev_ls => { "/dev/rdsk" => "ls-lR/of/dev_dsk",
"/dev/rmt" => "ls-lR/of/dev_rmt" });
my $tape = inst_to_dev("st1");

This module maps both ways between device instance names (e.g. sd0) and /dev entries (e.g. c0t0d0). Vanilla SCSI disks, SSA disks, A1000, A3000, A3500 and A5000 disks are all catered for, as are tape devices and NFS mounts.

FUNCTIONS

inst_to_dev($inst)

Return the device name name given the instance name

dev_to_inst($dev)

Return the instance name given the device name

get_inst_names

Return a sorted list of all the instance names

get_dev_names

Return a sorted list of all the device names

mapdev_data_files

This tells mapdev to use data held in copies of the real datafiles, rather than the current "live" files on the system. This is useful for example when examining explorer output. A list of key-value pairs is expected as the arguments. Valid keys-value pairs are:

path_to_inst => "/copy/of/a/path_to_inst",

A valid path_to_inst file. This is mandatory.

mnttab => "/copy/of/a/mnttab",

A valid /etc/mnttab file. This is optional - if not
specified, no information on NFS devices will be displayed.

dev_ls => { "/dir/path" => "/ls-lR/of/dir/path",
... });

A hash containing path/datafile pairs. The paths should
be one of /dev/rdsk, /dev/osa/rdsk, /dev/osa/dev/rdsk or
/dev/rmt. The datafiles should be the output of a "ls -l"
of the specified directory. A single file containing a
recursive "ls -Rl" of /dev is also acceptable.

mapdev_system_files

This tells mapdev to revert to using the current "live" datafiles on the system - see "mapdev_data_files()"

UDPcast project is a file transfer tool that can send data simultaneously to many destinations on a LAN. This can for instance be used to install entire classrooms of PCs at once.
The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses Ethernets multicast abilities: it wont take longer to install 15 machines than it would to install just 2.
UDPcast is released under the GPL 2.0 license.
UDPcast can be started from the included linuxrc boot disk for OS installations, or from the command line when using it for other purposes.
Enhancements:
- The kernel was upgraded to 2.6.21.3 and busybox was upgraded to 1.5.1.
- The code was adapted to Solaris 10 x86 by adding includes and configure checks.
- A patch was made to fix parallel make and make DESTDIR=/tmp/xxx install.
- gcc4 warnings were addressed.
