Hi admins & (admin companies), we are in need of ongoing server & system administration support. OS: Linux Debian. Currently we need to clean up the environment of one or our production servers. Also a deployment process for a App based on Python, Angular with postgresql as a db has to be developed and installed. Our developers need support hereby and in all general needs regarding system administration. Deployment should be: automated - triggered by a repo push to a certain branch for ex. (HTTP link for staging would also good) it should take care of database backups on each deploy easy rollbacks to previous version with one command (code only, database rollbacks for production should be separate, as it needs greater care) it needs to download all dependencies, build anything if necessary ​*fast*​ - we do not want to waste 15 minutes for something that would be done with simple script in 1 minute. The job is ongoing and we are able to identify able administrator - so please only apply if you have excellent experience. System Administration companies are very welcome (!)

Hi, I essentially need someone who has used cloud services such as AWS/Rackspace to configure a SaaS platform. Currently, everything is on one server (db, etc.) I need to move all of the services to their own servers and use ansible to manage the configuration, so we can spin up as many servers as we want. You should be able to configure load balancers, apache, mysql, etc. in the cloud. You should be able to take high level direction and deliver me detailed reports with what you've done.

We are looking for a Zabbix expert to assist with the setup and configuration of a new Zabbix monitoring system. There is an opportunity for additional work in the future for additional configuration. We would like a full Zabbix system install on a provided Linux machine. The Zabbix system should have email alerts available and a web interface for reviewing all system status. We would also like pre-defined templates created for both Windows and Linux systems that can be applied easily and on demand on local systems to be monitored. This should be properly documented for easy setup and connection to the Zabbix server. We would like a standard monitoring setup including the following: 1) Server uptime (including if server is online or offline currently) 2) Disk space usage and growth 3) CPU utilization 4) RAM utilization 5) Disk utilization 6) RAID Status 7) Network latency 8) Core system temperature Any expert suggestions on additional configuration is appreciated.

Need help setting up test environment for my project: Goal: Achieve IP connectivity between 2 hosts B to A; C to A; A) Hosts - host A is VM located behind Cisco ASA 5510 appliance - host B is Windows VM located in Azure - host C is Linux (Unbuntu or CentOS) VM located in Azure B) VPN - Host B and C need to have Stong Swan installed and configured to establish VPN site-to-site connection to Cisco ASA 5510 appliance - ASA5510 VPN temrination point must use certificates (self-signed / openssl ) for IKE Authentication. Both client VMs must use certificates as well - Site-to-Site VPN must be setup using IKEv2 proposals - Both Linux and Windows hosts must use SrongSwan as "client" https://www.strongswan.org/ - StongSwan configuration example https://www.strongswan.org/testresults4.html C) Cisco ASA 5510 is already in place, same as VMs. If you have your equipment - be my guest D) StrongSwan configuration: VPN tunnel shell only be "brought-up" by any traffic initiated by VM. Ping for example Private IP on VM is the only "network" that need to be terminated by VPN Need help actually configuring this setup: mostly - certificates (issuing, installing) - StrongSwant installation and configuration Outcome: - need working configuration - Step by Step documentation of this configuration: i.e. 1. Deploy StrongSwan on Linux with so-and-so 2. Generate cert like this 3. On Cisco ASA configure VPN like so and so. It has to be an understandable manual, short but to the point. (I am experienced engineer myself) No, there is no need to connect B and C, only C to A and B to A - there is no learning curve - i.e. if you have to do some research and testing - it is on your own. - In the end I will need remote session arranged to apply configuration to actual hosts. - I can give unattended access to cloud VMs, but not to firewall. - if you have your own ASA, be my guest; if you want to deploy Cisco virtual ASA (demo/eval) - be my guest. Access to my firewall have to be supervised. https://software.cisco.com/download/release.html?mdfid=286119613&softwareid=280775065&release=9.2.2.SMP.ED&relind=AVAILABLE&rellifecycle=&reltype=latest Even though I put per hour job, I would like to - get estimate of hours, - I prefer to pay fixed price - your availability
