Free round software for linux

Aranha is an application that uses an XML-RPC layer to retrieve information from one or more servers. The type of information gathered is implemented via plugins, and can be displayed or archived in several different ways.

The data is gathered in Round Robin Databases (integrated with rrdtool) and can be accessed using a XUL interface available from the system. Plugins are very easy to write.

Splendid City Team Sports Scheduler, and Sports Scheduling Software System is useful for people who organize team sports or game events. It can manage sports schedules of any size and complexity. Simply fill in the requested information into the wizard like interface, and Splendid City automates the season, tournament, league, match, round-robin and practice schedules.

A great first step and time saving tool for anyone who frequently does organizational sports scheduling. Splendid City can schedule sports with any user specified combination of dates and times. Create professional double or single elimination tournaments brackets, round-robin league schedules, swiss round tournaments, cross divisional or practice schedules for any sport that requires pairings.

It features options that include the ability to set team and field constraints, game lengths; configurative time management utilities to help you organize events the way you would like; object constraint sharing; automatic schedule generation and re-generation; configurative project web site creation, tournament brackets; publishing via FTP, export to HTML, CSV, iCalendar, XML; import from CSV; standings support with tie-breaker formulas; contact management; import teams, fields, officials, players and player rosters from other users projects ; constraint and conflict checking and resolution.

Users can freely exchange all data associated with projects with other users who have a free copy of Splendid City Lite installed regardless of platform. The application comes with an integrated e-mail client that can aid with the exchange of object files among organization members. There is also a simple FTP client for direct uploading to web domains from within the schedule view frame.

The scheduler gives you complete control over all aspects of the schedule, and creates solutions effortlessly and elegantly in accordance with the user data entered. It can be custom-tailored, and with repeated use via a plugin interface, can be made to automatically accomplish users unique scheduling needs.

The user experience is interactive and straight forward. The application comes fully documented with a built in searchable help system to provide answers to implementation questions.

MySQL Activity Report is a valuable database tuning aid.

The MySQL Activity Report package is a tool to help MySQL database administrators to collect several database parameters and variables. These collected values can be used for server monitoring or performance tuning purposes.

The most important component of the MySQL Activity Report is mysqlard. This daemon collects the data from a MySQL server and stores these values in a Round Robin Database.

The mysqlard package also contains example graphing, cron and php scripts. The cron scripts can be used to keep archives of the generated graphics and the php script shows the generated graphics and tries to give some tuning tips.

fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.

Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.

If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Problem and Issues:

With a large a number of IP addresses in use, its becomes more and more time consuming to check on which IP addresses are actively in use, and which critical machines (routers, bridges, servers, etc) are reachable. One example is we have a program which goes through all of our routers arp caches looking for IP addresses that are in use. After finding a list of IP addresses that arent in any arp caches fping can then be used to see if these IP addresses really arent being used, or are just behind the routers. Checking 2500 hosts (99% of which are unreachable) via ping can take hours.

fping was written to solve the problem of pinging N number of hosts in an efficient manner. By sending out pings in a round-robin fashion and checking on responses as they come in at random, a large number of hosts can be checked at once.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Xyria:DNSd is an high performance DNS server that supports only the most important features and resource records while being extremely fast and secure.
Xyria:DNSd peoject also supports round-robin load balancing.
Main features:
- extemely fast implementation (main target)
- very secure
- ip-address based listen()ing
- supporting IPv6 addresses and resource records
- load ballancing via round robbin
- running under an low-privileged UID & GID
- running under little endian systems: (at least) Linux, Solaris, OpenBSD
- nice configuration syntax/easy to configure
- DNSd able to forward querys
- DNSd can run as caching only-server
Enhancements:
- The database was modified. Now DNSd uses a hashed array of pointers to binary trees including single linked lists for double valued hashes.
- It sorts the zones (by TTL) by itself (the admin doesnt has to care in which order he has to place the zones in the config file).
- Some code cleanup and a small bugfix are also included.

L4ip is a daemon that extends IPFilters simple round-robin L4 load balancing with health checks. It takes care of monitoring and dynamically adding and removing ipnat rules in the kernel.
L4ip fully supports UDP, TCP, and system()-style executions for health checks, including send/expect scripts, SSL connections, and much more.
Main features:
- Define as many clusters, with as many members as you need.
- Automatically adds and removes "ipnat" rules as needed.
- Flexible health check support, tcp-open, tcp-close, udp-open, udp-close, system.
- Simple scripting available for health checks in send/expect syntax with fnmatch pattern comparison
- Binary protocol supported in url-encoding style syntax (eg %0D)
- system() like execution of external commands available. (spawn your own health-check testers)
- Reload and restart leaving last-known-state available for less service impact.
- SSL supported for TCP testers.
- Optional IPF rules to sense RST return-packets for faster failure detection.
Enhancements:
- Solaris SMF example files were added along with a "proxy" command for protocols that need it, such as FTP and IPSec.

JTourney is a Java based tool to support tournament directors conducting small to medium scale round based tournaments for multiplayer games.
JTourney tries to encaspulate over 10 years of experience with various tournament formats for different games. Those tournaments were conducted either manually or with the help (of many kind people and) a predecessor programm, which finally became too old and too small.
The need for JTourney arose since the tournaments conducted were rather flexibile: Players could hop on and hop off between rounds, the games played might allow variable number of players. Beside this flexibility JTourney could of course be used to support more rigid tournament formats, but this is not its focus.
Main features:
- Keeping player lists.
- Playcing players on tables for next round by variuos strategies.
- Generate score sheets for tables.
- Keeping track of game scores
- Calculating player scores, tiebreakers and rankings
How it works?
JTourney is a very simple design. It merely parses text files into its memory and composes new ones on design. While parsing its internal datafiles it also feeds this internal information to the RenderMode, therefore it provides you with more beautiful information than just the raw internal text files.
Note the system never stores things like standings or total scores of players internally. It turned out, that parsing input is very fast and never is a real problem for (say) 100 participants and 12 rounds (this is not a limit, it can most likely handle much more participants and more rounds) on a recent PC.
While this architecture is from the computer stone age it is flexible and powerful. Maybe a bit volatile, but after all it is entirely appropriate to put whatever kind of GUI on top if necessary!
