Free production hub software for linux

Open DC hub is a Unix/Linux version of the hub software for the Direct Connect network. Direct Connect is a file sharing network made up by hubs, to which clients can connect.
Once connected to a hub, the user can search for files on the hub or the network, or browse files of other users connected to the hub.
Main features:
- Searching for files
- Connecting to users, both in active and passive mode
- Messaging in open chat
- Private messaging
- Registering users
- Kicking users (for OP:s)
- Banning users (for Admins)
- Uploading hub address and description to public hub list
- Hublinking, which makes it possible to search on other hubs connected to the network
- Administration of the hub from chat
- Scripting (In Perl)
The hub is run as a daemon, i.e, it runs in the background. Its administrated through a tcp connection, for example with telnet, which makes it possible to administer remotely, given that the user has the administration password. Its also possible to administer the hub directly from the chat in Direct Connect.
The software should run on all POSIX compliant operating systems, but the main testing has so far been done on GNU/Linux-x86 and Solaris-Ultrasparc. Please tell me if you fail or succeed in running it on other platforms.

DConnect Daemon is a Direct Connects hub working as daemon. It works currently under linux and FreeBSD, but we want to make them work on all Unixes (and under Windows).
DConnect Daemon works as a daemon in background and does not require any Xwindow system. Everything should work without any maintenance, but with possible runtime manipulations.
Main features:
- written in pure C
- utilizes threads - allow to work faster on SMP mashines
- good and strict protocol implementation - as far as we know it...
- access limitation through libwrap
- telnet administration console and traditional with DC client
- flexible configuration
Enhancements:
- Because full support for syslog is included, the old way of logging to files was removed.
- Switch to syslog-ng is recommended as it will make your logs cleaner.
- Silent mode is now switched on so it is impossible to redirect users who should not have access to the service you provide.

mysqlrowcopy is a tool that generates insert statements from result sets. It produces output similar to what might result from running mysqldump on a single SELECT query.

This project helps eliminate some of the tedium of moving data between QA and production MySQL databases.

Build:

To build mysqlrowcopy, you should run:

./configure
make

A mysqlrowcopy and mysqlrowcopy.debug file are created. They have identical functionality, the .debug version simply has debugging symbols built in (for gdb).

Since mysqlrowcopy is probably going to be I/O bound with modest CPU and RAM usage, the only reason to even build a 64-bit version is to work around potential issues in dynamic linking 32-bit binaries against 64-bit libraries.

RECIPES

1. Migrating a MySQL user account reaper from QA server to a production server.

e.g. MySQL database server qa3.example.com to prod1.example.com:

$ mysqlrowcopy -h qa3.example.com
SELECT * FROM db WHERE User = "reaper" mysql db > reaper.sql
$ mysql -h prod1.example.com mysql < reaper.sql

You could of course simply pipe the output of mysqlrowcopy into mysql and skip the intermediate file.

(Dont forget to RELOAD PRIVILEGES afterwards)

2. Keep your test environment up to date. Populate it with production data every 24 hours. You could run this sequence from cron once a day:

$ mysqlrowcopy -h finance-db.example.com
SELECT * FROM stocks WHERE modified > DATE_SUB(NOW(),INTERVAL 24 HOUR)
finance stocks > day-stocks.sql

$ cat day-stocks.sql | mysql -h finance-test.example.com finance

3. Copy data between tables on different servers that have some similar fields.

Youve got common data in table Zip on a production database:

mysql> desc Zip;
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| ZIPCode | varchar(5) | | PRI | | |
| ZIPCodeType | char(1) | YES | | NULL | |
| City | varchar(32) | YES | | NULL | |
| CityType | char(1) | YES | | NULL | |
| State | varchar(32) | YES | | NULL | |
| StateCode | char(3) | YES | | NULL | |
| AreaCode | char(3) | YES | | NULL | |
| Latitude | varchar(12) | YES | | NULL | |
| Longitude | varchar(12) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
9 rows in set (0.00 sec)

And youve got table ZipPosition in a research database:

mysql> desc ZipPosition;
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| ZIPCode | varchar(5) | | | | |
| Latitude | varchar(12) | YES | | NULL | |
| Longitude | varchar(12) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
3 rows in set (0.00 sec)

You want to load data from production Zip into research ZipPosition.

$ mysqlrowcopy -h production SELECT ZIPCode,Latitude,Longitude common ZipPosition > pos.sql
$ cat pos.sql | mysql -h qa research

Note how we specify ZipPosition on the first line to tell mysqlrowcopy what the destination table is going to be.

Hpodder is a tool to scan and download podcasts. Such tools are often called podcatchers.
Hpodder is a command-line tool for Linux. The project has quite a few features. A few highlights are that it is easy to learn and use, has automatic discovery of feed metadata, and can import iPodder settings.
Enhancements:
- This is the first production release.
- Feeds or episodes that repeatedly return errors are now automatically pruned.
- Cleaning of download areas was improved.
- Bugs were fixed.

DCH# project is a DirectConnect hub designed to be easy to use and highly configurable as well as providing quality administration tools to operators.
Main features:
- C# Language - Runs on both .NET and Mono
- XML Configuration - Easily Configurable
- Plugins - Server plugins and protocol exensions
- Protocol Support - Supports ADC protocol and NMDC
- Logging - 4 different logging levels for your viewing pleasure
- Multi-Threaded Design - Multithreaded goodness
Enhancements:
- This release adds basic user authenication based on the Users.xml file and the PrivateID.

- This also adds the StatusPlugin and HubRules plugin.

uHub is a high performance peer-2-peer hub designed for UNIX-like operating systems. The project is written in C, has a clean design and small memory footprint. It is scalable, and will work for small hubs on embedded hardware, as well as big hubs running on high preformance servers with thousands of users.
uHub uses the ADC protocol (ie. the next generation Direct Connect), and is compatible with DC++, Elise, QuickDC and other ADC clients.
Unlike other peer-2-peer networks, ADC is centralized. Clients connect to a central "hub" to communicate with other clients. It can be compared to super nodes (or ultra nodes) in other networks, except the hubs do not openly communicate between each other. The advantage to such a design is that the hubs are in control on who can access the network.
Main features:
- Easy configuration
- Advanced access control support
- Ban by network address ranges, nick name or CID
- IPv4 and IPv6 support
- Event logging
- Fast with a low memory footprint
- Support for chat only hubs (optional)
- Support for registered users only (optional)
- Runs as an unprivileged daemon (optional)
Enhancements:
- This release fixes several known crashes and cleans up the code quite a bit.
- The event handling has been refactored, a memory handling debug infrastructure is in place, and the log file format has changed slightly.
- The code base is now automatically tested for regressions.
- This release changes the license to the GPLv3.
