Internally we run 2 MySQL Master Master replication servers. While we have had no problems with them managing them is an absolute nightmare. Adding new databases and users is painful. I decided to create a test MariaDB Galera cluster to see if that solves our issues. Continue reading
We recently upgraded our copy of our Storegrid Server and clients to 4.4. After the upgrade a couple of our customers 64 bit Linux servers (All Centos) Storegrid failed to start.
We have several customers (ourselves included) using Linksys SPA VOIP Phones. The only major issue with these phones is how they deal with Anonymous calls. When an anonymous call comes through even if a Caller Name is set they won’t show it and instead just display Anonymous Call. We often use the Caller Name to display what queue the call is coming from or in one case a Virtual Receptionist setup what customer the callee has called.
Now that DBMail and Roundcube are working it’s time to get push notifications working with Z-Push
Now we have DBMail running we can configure Roundcube to connect to it using IMAP. We are hosting our Roundcube on an existing webserver and just setting up a new virtual host for it.
Our first setup is to get Postfix and DBMail working. Postfix will handle receiving our email then hand it off to DBMail using LMTP (Local Mail Transfer Protocol) to store it in a Mysql Database. In this instance we already have a database server that we are going to use to store email so we skip that step however there are plenty of walk through out there if you need help.
With the recent news about how deep the NSA spying actually goes we wanted to see if we could actually pull back from the cloud. We host our email with Gmail for Business and have setup numerous customers using it as well. We also have customers using Office 365 which suffer similar problems, issues over data security.
This series of posts is to see if we can setup a comparable product to Google Gmail for Business/Office 365. The main features we want to replicate are a decent web interface, Outlook integration and Push email to devices. While we could using Exchange and host it internally if we want to offer it to customers in the future the pricing of SPLA makes it cost prohibitive.
The domain is now completely functionally it is time to sign the zone so we can start using DNSSEC. Continue reading
Now that our DNS servers are setup to at least answer non DNSSEC queries it is time to setup the domain.
Since we are moving to new name servers this will walk through setting up a master (ns1.1metric.com) and slave (ns2.1metric.com), if you are looking at implementing it on already existing name servers most of these steps can be skipped. Just do a skim below to make sure your new name servers are setup to support DNSSEC.
