I started my job at Novell PSH Inc. in April 2010 as a Linux System Engineer. I work with customers and operate with Novell, SUSE and Open Source products. The main tasks are: implement solutions, operate server, solve problems, communicate and give advices to our customers.
Implement security solutions that are based on NetIQ. Perform tasks on the customer side (define tasks, system design, implementation, track feature request and bugs).
Security Event and Information Manager system with NetIQ Log Sentinel. Participate in projects and implement solution to the customer.
Manage administrators and users in their environment with NetIQ Privileged Account Manager (auditing). Design and implement policy and rules to the customers.
I recognize the potentional security problems and patch them, keep the systems up-to-date. I follow software problems, research vulnerabilities and analyze logs.
The OTRS ITSM is an open source fundamental solution for IT Service Management in different organizations. I had to learn the program, implement and teach it to the customer. The final solution was made by customers unique needs.
The HUEDU project was relaunched on 1 September 2012. We were working on better solutions for problems and issues that emerged in the daily activities of schools. We developed a custom Linux distribution based on OpenSUSE. We only used Open Source softwares in the project.
Development tasks: We created huedu openLAB website in order to give permission to different user groups (students, teachers and admins). This is based on html, php and css program languages. We created some extra web functions for which we used java and jsp languages.
Services and Applications: DHCP/DNS, Cups, Samba, Tomcat, Apache2, Mysql, Mariadb, PostgreSql, openLDAP, postfix, MailScanner (clamav, spamassign, cyrus imap), Squid, squidguard, SuSEfirewall, iptables, OpenVPN, Quota kezelés, Kiwi, Roundcube, Ilias E-learning, OCS Inventory NG, Webmin
I translated Open Source softwares from their original languages to Hungarian:
I migrated the desktop environment to VDI (Virtual Bridge) solution. I also organized a team whose job was to test the software environment and report the results to the customers.
I managed to operate SUSE Linux Enterprise Servers in XEN virtualization with High Availability Extensions. My tasks were to implement and operate the technology and make a performance tunning plan and solve the issues. I migrated the outdated physical servers to this new environment.
Cluster solutions: virtual servers (XEN) and software (Oracle, apache2, etc..) clustering
I created and offered backup and disaster recovery plans for our customers. The core services must operate by cluster or mirror solutions. In case of errors i suggested system improvements.
I monitored the entire IT infrastructure by nagios. I made some unique checks and alerts which detect the problem before it arises and react immediately avoiding the service to stop. With the help of this system the customers can minimize or abolish the downtimes.
I supported customers’ Linux systems like SUSE Linux Enterprise Server 9, 10, 11, Novell Open Enterprise Server, RedHat 5 és 6, Ubuntu, Debian, és CentOS Linux and gave advice for administrator 'how to operate the services' without unplanned downtimes.
I created custom Linux distribution based on openSUSE with many Open Source softwares. The object of the project was to change the old system to the new one which uses Open Source products, so they can reduce the customers cost.
