We have an old Debian build as our firewall. It has IPtables managed by Webmin, VPN built into it, Mail relaying (anti-spam, anti-virus) this auto syncs with the Active Directory for Domain names (Websites) and users, Network Monitoring (I would like a gui and something robust like TCP dump or wireshark too). It needs to be upgraded. I can't even install TCP dump on the old thing. I am open to different builds but familiar with Debian and IPTables. We have a new box ready and most of the build done but having trouble with the LDAP connection to Active Directory.

Hi, I have an OVH dedicated server with: CENTOS 6.5 PLESK 11.5 PHP 5.33 MYSQL 5.1 It has been with those versions since March 2014. I haven't updated it for the last 2.5 years. But now I must updated it because I need PHP 5.6, so I would like to upgrade Plesk from 11.5 to 12.5, and I think when I do that upgrade from plesk panel, php and mysql may update automatically as well. But I want a professional to help me do this because my production server is hosting my apps and it is critical that this upgrade goes well. The plesk panel is giving me the option to upgrade from 11.5 o 12.5, when starting the process there are a couple of warnings that I don't understand, so I need the help of a professional. It should all be straight forward and easy but I prefer to do it together with a professional let me know how much you would charge me for helping me to upgrade my dedicated centos 6.5 server from plesk 11.5 to 12.5, which should also hopefully upgrade php from 5.33 to 5.6 and mysql from 5.1 to 5.5 i guess best Jav

I am looking for a full stack Developers. Specializing in ruby on rails. Plus you need to have console experience(such as aws). Linux experience is must. You will be integrating Dwolla into my website. Dwolla is a payment service for e-commerce sites just like Stripe. But they specialize in ACH. Which you will be implementing it in my existing app. The thing is that its not actually hard to implement Dwolla. But the hard part you will be working on is making it talk to my app. For example, a user deposit's $100 in his account on my app. That balance needs to be updated accordingly. Finally you will be working on my machine. I have the local environment setup, to reflect the recent changes made to the website. This will save you hrs. You will just need to turn it on i guess.
