For assist on Filezilla and ftp mention birthright here. Pre-requisite birthright here is that aixfix folder already exists. If no longer, traverse to the route.
suggests you the folder aixfix created.
9. Now returned to their AIX terminal..

Telnet to your AIX again and check oslevel.
you're a Sysadmin now! Bye
In my remaining tip, I compiled a listing of the precise 50 Unix instructions. each of the commands I mentioned are available on...
the excellent three Unix editions: Solaris, AIX and HP-UX. listed here, i may walk you during the legacy of these Unix flavors, talk about some their fundamental ameliorations and immediate with a command desk comparison of significant initiatives.
sun SolarisSolaris, solar's Unix version, become basically the successor of SunOS, going returned to1992. SunOS changed into originally in response to the BSD flavor of Unix, while SunOS types 5.0 and later are based on Unix paraphernalia V unencumber 4 (rebranded as Solaris).
How did this circle up? Let's fade extra returned in time. SunOS version 1.0 become added in 1983 with assist for sun-1 and solar-2 techniques. version 2.0 turned into brought in 1985 -- its declare to reputation changed into virtual file device (VFS) and NFS. In 1987, AT&T and sun announced that they'd toil collectively on a chore to merge gadget V and BSD into one free up, in response to SVR4. Solaris 2.4 changed into sun's first Sparc/x86 release. The remaining liberate of SunOS became version 4.1.4 in November 1994. Solaris 7 was its first 64-bit extremely Sparc free up and delivered indigenous aid for file gadget metadata logging. Solaris 9, introduced in 2002, introduced support for Solaris extent manager and Linux capabilities. Solaris 10 turned into first added in 2005, which has a number of improvements, together with usher for its fresh ZFS file equipment, Solaris Containers and analytic Domains.
Solaris is at this time up to edition 10; the newest replace become launched in October 2008. amongst its innovations is assist for paravirtualization, the position Solaris 10 is used as a visitor in Xen-primarily based environments.
fundamental alterations and unique qualities. Solaris is free and open supply, allotted through the OpenSolaris operating system. Solaris is a more command-line based mostly Unix operating device than HP-UX or AIX. As a practical be counted, it doesn't maintain anything similar to device Administration supervisor (SAM) on HP-UX or paraphernalia management Interface tool (SMIT) on AIX. Solaris runs on Sparc and x86 environments. It additionally has the latest file system around -- ZFS, which has made wonderful strides in recent years, together with the means to now expend it as its root file device. ZFS has the scholarship to be the most fulfilling all-round Unix file device. Solaris has many how to invoke virtualization, together with Containers/zones, xVM Server, analytic Domains and hardware partitioning.
Hewlett-Packard HP-UXHP-UX, Hewlett-Packard's Unix, turned into at the start in accordance with gadget V unencumber three. It in the beginning ran completely on PA-RISC HP 9000 platform. version 1 of HP-UX turned into released in 1984. edition 9, added its persona-primarily based graphical user interface (GUI), SAM, from which one administrates the gadget. edition 10, added in 1995, brought adjustments within the layout of the device file and directory structure, making it comparable to AT&T SVR4. version 11 turned into delivered in 1997 and turned into HP's first liberate to usher 64-bit addressing. In 2000, it was rebranded to 11i, when HP brought working environments, bundled corporations of layered functions for selected IT purposes. In 2001, version 11.20 added support for Itanium techniques. HP-UX became the first Unix that used entry control Lists (ACLs) for file permissions and was additionally one of the most first to interpolate built-in support for analytic volume supervisor. today, HP-UX makes expend of Veritas as its basic file gadget as a result of the shut partnership between Veritas and HP. HP-UX is currently as much as release 11iv3, update 4.
basic variations and entertaining qualities. HP-UX is the first of the Unix programs to enable its consumers to buy positive operating environments. as an example, in case you are looking for its elevated availability (HA) product Serviceguard, you would purchase the specific product that bundles in HA. HP-UX is the only edition that makes expend of a 3rd-party file device -- Veritas (solar used to present this many years ago). HP has many styles of virtualization, together with nPartitions, vPars, Integrity digital Machines (IVMs) and resource partitions. This does maintain a bent to confuse some individuals as a result of there are such a lot of choices. HP-UX runs on each HP 9000s and Integrity Itanium methods. HP-UX 11v3 can assist up to 128 processor cores. HP-UX provides for a very astounding command line apart from its menu bases system, SAM. efficiency tuning the expend of kctune is in lots of approaches less demanding to what AIX and Solaris offer.
IBM AIXAIX became added via IBM in 1986. whereas it's in line with Unix system V, it likewise has BSD roots and, greater than any other flavor, is a hybrid of both. AIX is the first OS to interpolate a journaled file gadget (JFS). It turned into additionally the primary to maintain an built-in analytic quantity manager (LVM). IBM first ported AIX to its RS/6000 platform in 1989. edition 5L was a leap forward free up added in 2001 that supplied for Linux affinity and analytic partitioning with the Power4 servers. In 2004, AIX introduced virtualization in AIX 5.3. superior vim Virtualization (APV) provided micro-partitioning, shared processor swimming pools and Symmetric multi-threading. In 2007, IBM better its virtualization product, coinciding with the unlock of AIX 6.1 and the Power6 structure. It likewise rebranded APV to PowerVM. The AIX enhancements included a sort of workload partitioning called WPARs, which can be comparable to than Solaris zones/Containers however with more suitable performance. The latest free up is AIX 6.1.
primary differences and unique traits. IBM is greatly recognized as having the most fulfilling virtualization product on the midrange, PowerVM. Some recent improvements comprise are living application mobility (permitting one to fail over working partitions with out taking downtime), energetic recollection Sharing and multiple shared processor pools. No different flavor of Unix can boast these virtualization qualities, nor can they match IBM's 40-yr background of virtualization -- PowerVM has developed from mainframe/gadget z virtualization.
AIX runs most effective on IBM vigour programs -- conveniently the strongest of midrange Unix servers. IBM sells the fact that AIX runs exclusively on vim as a plus since it is thoroughly optimized on this structure and it has a limpid road map round which the company adheres to religiously. it'll likewise be illustrious that you will race both Linux and AIX partitions on this platform. Its LX86 virtualization add-on makes it feasible for one to race x86 Linux applications that are not ported to the power structure. AIX has every the time had an integrated analytic volume manager, not dote other flavors that require add-on products. AIX is the most effective Unix that has continued to develop market share in recent years, partly as a result of the capabilities of its vim hardware that continues to steer the realm in reliably, availability and scalability.

Even with the popularity of open source and Linux, commercial Unix platforms are silent an significant fragment of most data centers. The most widely used versions of Unix are IBM's AIX, Hewlett-Packard's HP-UX and Solaris from Oracle-Sun. In this tip, I present an overview of recent enhancements made to each of these Unix distributions.
AIX 6 was released in November 2007 and updated in October 2009. AIX 7 was just released in August 2010. Since AIX 7 is brand new, I'll examine features of both versions.
AIX 6 and 7 are available in three editions:
Express Edition: economical and intended for smaller workloads
Enterprise Edition: includes additional management capabilities
AIX 6 introduced Workload Partitions (WPARs), software-based virtualization that allows multiple AIX environments to race on a unique system. WPARs provide isolation from other processes and WPARs. Each WPAR may maintain unique administrator control, network addresses, file systems, users and groups. Processor and system resources are shared and apportioned between WPARs.
WPARs share a unique global instance of AIX as compared with analytic Partitions (LPARs), each of which runs an independent copy of AIX. When the WPAR global instance is patched, every subordinate WPARs inherit the patch. AIX 7 adds Trusted Kernel Extensions, which can restrict access to specific kernel extensions to particular WPARs. With Life Application Mobility, applications in a WPAR can be moved without stopping and re-starting, so workloads can be balanced across multiple systems.
AIX 6 likewise provides numerous security enhancements:
Role-Based Access Control is used to vouchsafe management access to specific users.
Trusted AIX provides compartmentalized multi-level security, allowing restriction of access to specific system resources and devices, such as partitions, networks or printers.
The enhanced journaled file system extended now provides an encrypted file system (EFS) using a variety of encryption algorithms.
The fresh secure by default installation option restricts the system and network services to the minimum to maximize security.
Trusted execution mode verifies application integrity via digital signature before execution to reduce the risk of software tampering.
Cryptographic framework provides hardware acceleration for cryptographic functions, such as those used in the EFS, IP security or trusted execution.
Availability enhancements in AIX 6 include:
Concurrent kernel update allows positive modifications to be made without requiring a system restart.
Dynamic tracing simplifies debugging by allowing probes to be placed in existing application or kernel code without requiring recompilation.
AIX 7 introduces Cluster Aware, which provides commands and APIs to create clusters of individual AIX systems. These clusters may be managed as a unique group, you can monitor events and disk space, and performance data for the entire cluster is available.
Also fresh in AIX 7 is the Event Infrastructure, used by Cluster Aware, which can monitor pre-defined system events.
HP-UX 11i was originally released in 2000 and the latest major version is HP-UX 11i v3 (11.31), released in 2007. The latest update (6th) to 11.31 was in March 2010.
HP-UX is provided in one of four combinations of operating system and application bundles, called an operating environment (OE):
Base (BOE) is the criterion version.
Virtualization Server (VSE-OE) is BOE plus the HP Virtual Server Environment and GlancePlus monitoring tools.
High Availability (HA-OE) is BOE plus Serviceguard availability tools and GlancePlus monitoring tools.
Data center (DC-OE) is every of the above.
The Virtual Server Environment provides virtualization capabilities and workload management tools. Hardware and software isolation is achieved using a hard partition, or nPartition, which establishes boundaries that completely protect one virtual machine from any faults in another (including software, hardware or electrical faults). In HP-UX 11.31, dynamic nPartitions can be modified while the partition is in use.
Software-only isolation is achieved using a virtual partition, or vPar, which runs its own instance of HP-UX and has its own share of CPU, recollection and I/O. HP-UX 11.31 introduces dynamic recollection migration between vPars and allows mixed vPar versions within a unique nPartition.
Dynamic Root Disk allows cloning and updating of a running root file system, assisting in system recovery and reducing downtime during upgrades.
Unified File Cache integrates the different mechanisms used for file caching: page cache and buffer cache. This eliminates the possibility of file system inconsistencies when using system calls that depend on differing mechanisms.
Encrypted Volume File System 2.0 provides AES encryption at the file or volume level. Security containment isolates system resources and provides fine-grained privileges and role-based access control.
Solaris 10 was first released in 2005. Updated releases are named by the month and year of release. The latest update, likewise called Update (U8), is Solaris 10 10/09, released in October 2009.
The Zettabyte File System (ZFS), introduced early in Solaris 10, can now support the root file system and be used to boot the system. support for user- and group-level disk quotas has likewise been added to ZFS.
Solaris Zones and Solaris Containers provide virtualization and resource containment. Zones seclude one or more application services within the operating system. A Container is a Zone that likewise manages operating system resources to obviate one Zone from consuming every actual system resources. Recently added resource management features allow CPU usage to be limited in multiple ways: fair-share, capped or dedicated. recollection and network bandwidth resources can likewise be managed.
A Zone may establish a divide instance of the TCP/IP networking stack through an Exclusive IP Zone, allowing the Zone to maintain a unique network configuration.
Logical domains (now called Oracle VM Server for SPARC) provide a higher flat of virtualization abstraction. A analytic domain runs a virtual machine within which an operating system can be booted, halted and rebooted (requires Solaris 10 11/06, U3, or later). Other operating systems supported by SPARC hardware may likewise be supported. Ubuntu Linux can be race in a analytic domain.
Many security features previously available in a special release of Solaris called Trusted Solaris maintain been incorporated into the regular release as of Solaris 10 5/08 (U5). Solaris Trusted Extensions comprise fine-grained privileges using Mandatory Access Control for policy-based access to system resources such as devices, files, networks, printing and window management. User Rights Management provides role-based access control and complies with the Federal Information Processing Standard.
