For those of you who are wondering, what this page is all about...
convers is a network of servers throughout the world running one of the many versions of conversd - a program which enables clients connecting to any of the servers to instantly communicate with anyone else on the network.
After a client connects, the user selects a channel and any message typed appears on the console of every other user in the same channel, worldwide.
A lot of the servers are running over the amateur radio packet network and RF links are a big part of the system. There are a few "hubs" that help glue the RF network together via the Internet - London_UK is the primary European hub.
If you run a convers server and want to link into the network, you should link into the nearest hub to you geographically. London_UK if your server is in Europe or Ma_us_hub if you are in the Americas.
Please link only to ONE hub, if you want to set a backup link, please comment it out in your config and only enable it if you cannot connect to your first choice. The biggest problem on the convers network is loops caused by badly configured servers, please help to eliminate these problems, not add to them!
If you are interested in joining the convers network, and you are located in Europe, please feel free to link to London_UK on 195.66.148.20 port 3600
London_UK is running conversd saupp-1.62a on Fedora Core 5 Linux. The original homepage for this software appears to have gone AWOL, so if you want to download the source code, I have made it available HERE
The operating system itself is running on a Virtual Server, i.e. a "slice" of a physical server, the virtualisation software used is OpenVZ. The underlying hardware is a Dell Poweredge 2U rackmount server, it has two dual core Xeon processors running at 1.6GHz, with 4GB of physical memory and four 120GB SATA HDDs, three of them form a RAID 5 array, the fourth being a hot-spare.
The server is connected to via two 100Mb/s network ports to a Cisco 3500 series switch, the switch is connected via two 1Gb/s ports to two routers, these routers form a HA (High Availability) pair, sharing one IP address for the networks default gateway. The routers themselves each have one Gigabit connection to an upstream transit provider whom they talk BGP to, they also have another Gigabit connection (each) to LIPEX, a London based Internet peering point, where ISPs can interconnect to exchange traffic.
In case you hadn't guessed, I am technical director for an ISP Nonanet (UK) Limited which explains how a poor amateur can afford such a good server with such good connectivity!!
