1. Endersys’in Ar-ge çalışmalarına Tübitak’tan bir destek daha
2. Endersys Türkiye’deki ilk ve tek Red Hat Advanced Business Partner oldu.
3. Endersys Türkiye’nin en hızlı büyüyen 17. şirketi oldu.

UNIX/Linux konularında ürün ve danışmanlık sunan Endersys Ltd firması, Netsara firmarsının Xmanager ürün ailesinin yetkili satıcısı oldu.

Xmanager ürünleri çoğu UNIX/Linux sistem yöneticisinin favori  araçlarından biridir.

Xmanager Enterprise sürümü  Xmanager, Xshell, Xftp, Xlpd modüllerini içermektedir.

Xmanager:  X uygulamalarını Windows ortamına taşıyan pazarın önde gelen PC X sunucusu yazılımıdır. Xmanager, uzaktan UNIX tabanlı makinelerde yüklü X uygulamaları, Windows uygulamalarının yan yana çalışmasını sağlar.  Xmanager,  güçlü bir oturum yönetim konsolu, kolay kullanımlı X uygulama başlatıcısı, X sunucusu profili yönetim aracı, SSH modülü ve uak UNIX/Linux ortamları için yüksek performanslı PC X sunucusu sağlar.

Xshell: SSH, SFTP, TELNET, rlogin ve seri port erişimini destekleyen güçlü bir terminal emülatörü.

Xshell diğer terminal emülatörlerine bulunmayan birçok kullanıcı dostu özellikler sunuyor. Bu özellikler, sürükle ve bırak, dosya adı, basit mod, tam ekran modu, şeffaflık seçeneği ve özel bir düzen modu seçerek Zmodem dosya indirme Zmodem dosya upload içerir. Bu özellikler terminal görevleri yaparken, zaman ve emek tasarrufu sağlar.

Xftp: Güvenli bir ağ üzerinden dosya aktarmak için gereken kullanıcılar için esnek ve hafif  SFTP / FTP istemcisi. Doğrudan düzenleme, birden çok bölme, klasör senkronizasyonu, FXP desteği, sunucudan sunucuya transfer ve 3. parti editörü entegrasyonu gibi güçlü özellikler sunar.

Xlpd: Basit bir satır yazıcı servisi ve Windows için baskı iş yönetim aracı. LPD protokolünü kullanarak uzak sunuculardan yazdırma işlerini alır ve bir yerel yazıcıya yazdırma işlerini gönderir. LPD, UNIX, Solaris ve Linux yıllarca gibi çeşitli işletim sistemlerinde standart yazdırma protokolü olmuştur. Hemen hemen her işletim sistemi desteklendiğinden karşı tarafta ek bir kurulum gerektirmemektedir. Bu, tek bir PC için basit bir LPD ya da şirket merkezi bir yazıcı sunucusu olarak kullanılan çok sayıda baskı işlerini yönetmek için esnek bir baskı çözümü. Xlpd, Xmanager ve  Xshell üzerinde çalışılan dosyaların çıktısını alabilmektedir.

Xmanager Enterprise sürümü yukarıdaki bahsedilen düm modülleri içeren en üst sürümdür.

As you can see we have a new yum transcation with an ID of 14. On that procedure we have updated openldap-devel and also openldap package is being updated. Lets see how openldap-devel package was upgraded


yum history packages-list openldap-devel
Loaded plugins: presto, product-id, refresh-packagekit, rhnplugin, security, subscription-manager
Updating Red Hat repositories.

-------------------------------------------------------------------------------

12 | Update | 2.4.23-15.el6_1.1.x86_64
1 | Install | openldap-devel-2.4.23-15.el6.x86_64


As you can see transaction 14 (ignore transaction 13 for now becase i have done that redo procedure twice) updates opendevel package from 2.4.23-15.el6.x86_64 to 2.4.23-15.el6_1.1.x86_64

Now it is a good time to undo transaction 12

Background

When you make a purchase from Red Hat, you are buying a subscription. A subscription gives you the right to access particular Red Hat services for a period of time on one computer. Once it is applied to a computer, the “right” becomes an “entitlement”. The services you receive include easy access to Red Hat’s software downloads, security and errata updates, access to knowledge resources such as in-depth technical papers, videos and knowledgebase articles, and access to a certain level of technical support — all through our Customer Portal.

You need one subscription for each computer you expect to use Red Hat software or services on. To designate which computer you plan to access Red Hat services from, you must first register that computer, and then you must assign an subscription to that computer directly — a process called Entitling. During the Entitlement process, an Entitlement Certificate is created on your computer. When you download software to your computer from the Red Hat Content Delivery Network, the Entitlement Certificate authenticates and authorizes the computer to receive the requested software services.

Changes to Subscription Management

Prior to this change, Red Hat has used a “pool model” for counting subscriptions, in which we track the total number of subscriptions a customer has purchased, the total number of the customer’s systems that are using subscriptions, and the difference between the two numbers. This model, which will now be called RHN Classic Subscription Management, is simple and effective, but has limitations, including an inability to link a specific subscription with a specific system.

As our product range expands, we’ve needed to change the way we track the subscriptions that our customers purchase and use. Our new model, called RHN Certificate-Based Subscription Management, keeps track of specific subscriptions assigned to specific computers using x.509 certificates.

UPDATE: To see if there is any patch (rpm) release just see https://bugzilla.redhat.com/show_bug.cgi?id=689622

UPDATE2: Red Hat Released RPMs for that for details see http:
//rhn.redhat.com/errata/RHEA-2011-0378.html You can use up2date -u tzdata or yum -y upgrade tzdata (no reboot required). Also update tzdata-java rpm if you use java.

tzdata-2011d-1 package solves this problem

You can check it before and after applying update:

1. Endersys becomes First Red Hat Advanced Business Partner in Turkey focused on Infrastructure Solutions

Here is how to do that in Red Hat Enterprise Linux:

Files to configure:

/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0


And here is the contents of that file

First /etc/sysconfig/network file should contain

NETWORKING_IPV6=yes


then /etc/sysconfig/network-scripts/ifcfg-eth0 file should be edited:


DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
HWADDR=00:30:48:33:bc:33
IPADDR=202.54.1.5
GATEWAY=202.54.1.3
NETMASK=255.255.255.248
IPV6INIT=yes
IPV6ADDR=2607:f0d0:1002:0011:0000:0000:0000:0002
IPV6_DEFAULTGW=2607:f0d0:1002:0011:0000:0000:0000:0001


As you can see above this machine has both IPv6 and IPv4 address which is very reasonable for at least 2 years on transition process. IPV6ADDR and IPV6_DEFAULTGW states. But be aware that there is no IPV6_NETMASK or something like that you have to use IPV6ADDR for that:


IPV6ADDR="3ffe:ffff:0:1::1/128"


More available sysconfig variables for IPv6 is at your RHEL installation at /usr/share/doc/initscripts* directory and /usr/share/doc/initscripts*/sysconfig.txt file
