    Hi there, I am a 30 years certified System Administrator you wish getting help from : I am an LPI(101 & 102),RHCE certified, Automation king!! I have rich experiences in a wide range of software and systems over the last 15 years, the most notable skills are : 1-Linux System Administartion : I have installed, configured, repaired, and managed so many Linux systems (more than I can remember) since 2006. I started with Fedora, then centos and ubuntu. 2- Scripting (My Favorite!) : I do enjoy very much with scripting especially for automation purposes, and I am very experinced with it, on both linux (bash) and windows (autoit - batch). I can automate all the tasks even those that don't talk to the command line in windows. I made for example in past, a fully unattended Windows installation CDs that is fully customized to include all the software my customers need without asking single question ! and on Linux I use Bash scripting Language to handle almost every aspect of linux and I did wrote so many scripts for various tasks. 3- Hosting Services : I have installed and managed previously many control panels for hosting and administration, that includes Cpanel, Plesk, ISPconfig, Webmin, Usermin, AWS, DigitalOcean, rackspace, cloud providers and more ! and in addition to that I can run the hosting services directly myself with no need for a control panel. I managed standalone software like : Apache, MySQL Server, ws-ftpd, proftpd, lighttpd with fast cgi, thttpd, dovecot, postfix and other servers ! I can also build/manage any hosting services, including shared hosting, VPS and dedicated servers. 4- VPN Services: I have installed and configured many servers that provided VPN services, including PPTP and OpenVPN services. I have even created a custom control panel for the customers and link it with automation scripts I wrote to better help the client managing his customers. (see the following picture): http://img687.imageshack.us/i/screenshotrsl.png/ And besides I am the solo developer of vpnplatform (vpnplatform.org/team) ;) and my clients consider me the best VPN guy on odesk. 5- Figting Malware: I can get your windows box clean even from the hidden malware and spyware trojans. I can secure your box and keep it safe and protected. I have fought malware since 2001 achieving great results like : cleaning big networks from viruses and worms and keeping it up and running in hostile environments for months with almost no downtime ! Also, I've built an app I called (Automated Malware Wizard), that would backup clinets hard drives and then GUARANTEE the cleaning of them, then update their software to close any possible vulnarables. I can customize it to you to fit your needs (If you intend to run a malware-cleaning and maintainance firm/utility). 6-Networking : I've been an ISP CEO before, and delivered internet services for more than 200 local subscriber when I worked at Hamad ISP. 7- VOIP: I am familiar with Asterisk and Asterisk GUI Installations, from scratch to fully working installation ! 8-Virtualizaion : I am very good with VMware and VirtualBox, I used them for years as a combination with hosting services. 9-Managing Mailing lists : I can manage your Email lists and make it away from SPAM lists by playing fair and square, I managed lists before, some of them got thousands of subscribers, I can clean the list also of all invalid/outdated subscribes by catching all email bounces using (my experience was with phplist script). 10- PHP/MySQL : I can develop web pages using a mixture of several technologies including html/css/php/mysql/javascript. And Finally, I can perfectly read, write and talk English Language and you can contact me over email, sms or mobile ! I perfectly speak English Language. I am ready to move to your job location if needed. I respect my work and give it every effort I can while keeping job's secrets secured and not to be shared with any 3rd party. You may see my attached C.V. and my odesk profile at: https://www.odesk.com/users/~~9b6150fc1d75d477 Note: I can adjust my availability time to suite your needs. Best wishes Ahmad  less

Over the last 7 years I've been a tech support for an ISP, a systems & network administrator and a web developer. As a network administrator for 2 years, I discovered what it means to maintain a large-scale MAN (Metropolitan Area Network), including internet access, setting up and managing IPTV streaming through IGMP and IGMP snooping techniques. I've setup BGP so the provider can have a backup route for his services. I'm falimiar with the nature of the technical issues that can occur and the different ways of handling and preventing them. I'm experienced in ethernet & GePON networking equipment. I've managed network equipment from most major vendors, Cisco, HP, DLink, Dell and Fundry, just to name a few. I've been working with Debian GNU/Linux professionally for 2 years as a systems administrator for a Bulgarian tourist resort and 2 years maintenance the services infrastructure (web, mail, vpn, samba, domain management, monitoring, ticket resolution systems, asterisk voip). I worked at a web development company for a year, doing back-end web development with different and frameworks, such as django, rails, express.js, along with infrastructure administration tasks and support.
