    Linux specialist (Sec/Opt/Dev, C/Perl/Python/PHP/BASH)

    Belarus - Last active: 1 day ago - Tests: 5 - Portfolio: 13

    I have over 15 years of work experience with Linux systems. This is the list of software and technologies with which I deal. This list is not full and expands day by day. I always can find right decisions if I found some problems. And I am always interested in looking for mostly economical and productive solutions. Of course, Cpanel, WHM, Webmin, Plesk .... I know how are working these web-wrappers and I support their. I can will tune and to make the checking of these wrappers. But that more important !! I can work without this))) Directly use configuration files of services and etc etc. Usually, it is better way on dedicated servers. ) TCP, IPv4 , IPv6, IPX ... - WiFi, WEP, WPA, WPA2 ... - SElinux, Apparmor, Smack, Tomoyo ... - LAMP ( Apache, Nginx, PHP, Perl, Mysql, Mongo), REDMINE ... - Cpanel, Zpanel, ISP ... - MySQL clustering and replication DNS servers ... - SENDMAIL, EXIM, POSTFIX (POSTFIXADMIN,MYSQL,DOVECOT,POLICYD) ... - HPC system: Torque, Maui, Moab for HPC clusters, Infiniband, FC interconnect, iSCSI, SCST, DRBD, OFED, OPENMPI ... - OpenLDAP ... - VPN with OpenVPN, PPTP, StrongVPN ... - Nagios, Zabbix, Ganglia, OSSEC ... - SVN, CVS, GIT ... - KVM, Xen, OpenStack, Proxmox ... - NBD, RAID, LVM ... etc etc During these years I have been in a large number of tasks related to administration of network devices, as well as with simple and complex server systems. I manage servers for the HPC tasks and for network infrastructure of Internet and Intranet - DNS,DHCP,*FTP,HTTP(S),MAIL etc etc. The main goals - the monitoring of the performance and the security. I also implement tasks of data backup and troubleshooting, support for the users. I have comprehensive work skills with systems based on Debian, Redhat, CentOS, SLES, OpenSuse. I've got more than 8 years of experience in developing the different software with use of C, Perl, Python, Bash, HTML on system and user levels. For example, very important skill in developing and the modification of RPM packages (rpmbuild, rebuild, kernels), custom kernels and etc etc. How the standart service for VPS's and VDS's projects and dedicated servers: IDS, IPS, the control of contents of log's files, the control of load of the cpu, the memory, the hard disks; the backups of the databases and the files; install or update software, consultations. Emergency call via sms to cell phone. STOP Windows and U/K/buntu etc. TIPS WITHOUT PAYMENT: =============== 1. VERY OFFTEN: IF YOURS WP WAS HACKED 1. disable plugins 2. execute # diff -r dir1 dir2 3. repeat for plugins if you have last version of WP code: ~ 80% cases - problems: plugin low quality (look on author: from where and who is) ~ 15% cases - problems: theme low quality (look on author: from where and who is) ~ 5% 0day of WP also you need disable all shell function in php and enable suphp/suexec modes. =============== 2. I am getting a lot questions about reliability and quality distributives/clones Ubuntu. Results on practice - Ubuntu clones - worst for server. It is truth. If you $buntu guy, I can't help you right now. I only can recommend Debian way for server. =============== 3. Nginx of course is good program. For small/middle vps. But in serious projects - apache. Nginx will be suitable for frontend. It is only practice. Always for all web application should be mod_security module. Firewall of level of web application on 7 level of OSI. Each web application/site should be under own user in environment of vps or on dedicated servers. =============== etc etc Sunday - day of rest. Or in emergency case - payment with double rate. best regards, Andrei odesk.by / upwork.link PS: With love from USSR. ;-)

    Technical Consultant

    Philippines - Last active: 5 months ago - Tests: 11 - Portfolio: 2

    Started out as a web developer, now a (certified) database and system administrator. I have over 3 years of experience with working, as a consultant, with companies from different industries (manufacturing, financial, telecommunications). Technologies I am familiar with include installation, configuration, and administration of Oracle Databases (with RAC, DataGuard, partitioning and other database-related products and features) and various Linux systems. Recently, I have started working with Oracle engineered systems as well. My development experience allows me to see creative ways of seeking solutions to various issues I encountered by me or my clients. This is something I have proven to be quite valuable in this trade. I am looking for opportunities that will expand my knowledge with the technologies I have been working with and in turn, improve current systems for you or your company. That being said, I amenable to looking into other systems/technologies I may not be well-versed with in order to complete client requirements properly.
