Hello, We would like to setup an Ushahidi 3.x instance. This is proof-of-concept (POC), and no customizations will be needed, although the instance needs to be fully-functional. You will have a VM all to yourself, and while this will be a POC, we would prefer an "elegant" setup of the underlying machine (e.g. folders, services not running as root, etc.) The target VM will be running CentOS (likely 7.x), and you will have full SSH access. We can leave the installation of MySQL, PHP, and Apache to you, including the minimum configuration to get Ushahidi 3.x to work. That is, there are no other competing resources, and this is not a production system. We hope it will become one, eventually. At the end of the setup, we will test the functionality, and will ask you to present a few notes, including setup choices, passwords (both for Ushahidi and underlying systems, like MySQL), configuration (e.g. Apache virtual directories), etc. It does not need to be a long document -we act...

Hi, I have 3 CentOs servers, two slaves that sync to a master. Clients get IP based on their location into the database. I am confronting the following issue: - some clients are not able to get an ip address from the dhcp server, I can see that they get through ( by using tcpdump ) , but they only get a DISCOVER but are not able to get an ip. I need an Experienced Linux Administrator who can help me solve this problem.

Greetings, I am setting up my server (CentOS 6.x) and have a couple of somewhat unusual issues with my postfix / dovecot setup (using Mysql): 1/ I need to keep both unix as well as virtual users, but I cant seem to set the mail server up so that clients can pick up emails for both and in particular have clients authenticate with left hand side credentials only for unix users ('john') and left+right hand side for virtual users ('  [obscured]  ') Server side, I do not mind where the emails land (ie: /var/spool/mail or together with virtual users such as /var/vmail/ or similar) 2/ I also am having trouble aliasing virtual domains (ie: have a virtual domain point to another virtual or hosted domain) - but that is just an inconvenience I have a work around using catchall and aliases Ultimately, I need the mailserver to be reviewed to ensure it can handle incoming and outgoing emails for both unix and virtual domain users, and serve the incoming emails to clients (web based or appli...

I am looking for someone to optimize and secure my Digital Ocean VPS. It is running: CENTOS 6.6 x86 With WHM/Cpanel software ALSO: I recently have had memory timeout issues where MYSQL database uses too much RAM and times out causing my server to crash. I would like someone extremely knowledgable in how to get a server running as fast and secure as possible, and also knowledgable in optimizing MYSQL to run in the most efficient manner. If there is anything that you can setup that would automatically restart MYSQL when it crashes, that'd be good too. I know next to nothing about this, and I need to be able to trust your ability. (Must have many reviews doing exactly what I am asking.) I upgraded my VPS yesterday in order to (hopefully no longer run into the memory issue, but I still would like it optimized and fixed.) Thanks, -Josiah

I currently have whmcs setup with the freeradius module to automatically bill and provision OpenVPN accounts. I am missing functionality and I need help adding it. 1) Currently it is not possible to assign users dedicated IPs. I want to have a pool of ips I can add to whmcs once the virtual adapters have already been setup that will be issued to new customers and ips will be added back to the pool should a customer be suspended or cancel. Something like this is possible with openvpn already   [obscured]  /blog/openvpn-set-a-static-ip-address-for-a-client/ but it only assigns internal ips not external public ips and is not an automatic process. 2) The whmcs freeradius module includes bandwidth limitation for example setting so someone can only use 200gb. It does not include rate limiting for example 20mpbs download/upload. I need to be able to set rate limit for users in whmcs. My operating system is centos, I am not using something like RouterOS but I am open to installi...

This should be a really simple solution for the well versed contractor. After a system update, my server receives the error: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:443 no listening sockets available, shutting down Unable to open logs This worked before a regular, automatic system update. My CentOS server uses nginx and reverse proxy apache. I'm looking for someone who can log in and in little time, fix this problem. Ideally, I would like to work with someone who would also be interested in monitoring the server system on a weekly or bi-weekly basis, and make necessary steps / improvements when necessary to ensure the server remains secure and functioning optimally.
