www.best.com/~doosh/netrek/netrekFTP.html -> www.inl.org/netrek/netrekFTP.html Blessed Clients Summary: The compiled binaries listed under this category are 'blessed,' which means that most servers will accept them at all times (unblessed clients get booted out). Most servers are now accepting only RSA-blessed clients. With some RSA clients, you need to use -R on the command line to enable RSA blessing. There is also a FONTBASED version for the sun 3 which uses fonts instead of bitmaps for the ships; Still immature, but possibly the best client for Windows users. This client expires periodically, requiring you to get a new copy. It is recommended that only people who know what they're doing use this client at this time. The client does not yet support RSA, so it will be kicked out of most servers. Unblessed Clients (borgs) Summary: The clients listed here are not blessed and will be booted out of servers which do binary checking. If you want to create a borg, get the source of one of the other clients and start hacking. Server Source Summary: This is a listing of all known netrek server source code. Before you try to set up a server, make sure your sysadmin approves. Also, running a server takes rudimentary programming skills and the ability to understand and use 'make' and other Unix tools; The vanilla server distribution now includes chaos mode, hockey mode, INL mode, base practice mode, and dogfight tournament mode. This is a collection of netrek-oriented utilities, some for server gods and some for netrek players. There are probably more out there which I've failed to list. Tips/Advice Summary: These are collections of advice for new players as well as old-timers. INL Stuff Summary: This is where you can find stuff related to the International Netrek League. |
ee-staff.ethz.ch/~oetiker/webtools/mrtg/mrtg.html -> people.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg.html Perl MRTG is written in Perl and comes with full source. Portable SNMP MRTG Uses a highly portable SNMP implementation written entirely in Perl (thanks to Simon Leinen). SNMPv2c support MRTG can read the new SNMPv2c 64bit counters. Reliable Interface Identification Router interfaces can be identified by IP address, description and ethernet address in addition to the normal interface number. Constant size Logfiles MRTG's logfiles do NOT grow thanks to the use of a unique data consolidation algorithm. Automatic Configuration MRTG comes with a set of configuration tools which make configuration and setup very simple. Performance Time critical routines are written in C (thanks to the initiative of Dave Rand my Co-Author). GIF free Graphics Graphics are generated directly in PNG format using the GD library by Thomas Boutell. Customizability The look of the webpages produced by MRTG is highly configurable. DETAILS MRTG consists of a Perl script which uses SNMP to read the traffic counters of your routers and a fast C program which logs the traffic data and creates beautiful graphs representing the traffic on the monitored network connection. These graphs are embedded into webpages which can be viewed from any modern Web-browser. In addition to a detailed daily view, MRTG also creates visual representations of the traffic seen during the last seven days, the last five weeks and the last twelve months. This is possible because MRTG keeps a log of all the data it has pulled from the router. This log is automatically consolidated so that it does not grow over time, but still contains all the relevant data for all the traffic seen over the last two years. Therefore you can monitor 200 or more network links from any halfway decent UNIX box. You can even use an external program to gather the data which should be monitored via MRTG. People are using MRTG, to monitor things such as System Load, Login Sessions, Modem availability and more. MRTG even allows you to accumulate two or more data sources into a single graph. HISTORY In 1994 I was working at a site where we had one 64kbit line to the outside world. Obviously, everybody was interested in knowing how the link was performing. So I wrote a quick hack which created a constantly updated graph on the web that showed the traffic load on our Internet link. After a few updates, I left my job at DMU to start work at the Swiss Federal Institute of Technology. One day in January of 1996, I received email from Dave Rand asking if I had any ideas why MRTG was so slow. MRTG's programming was not very efficient and it was written entirely in Perl. After a week or so, Dave wrote back to me and said he had tried what I had suggested for improving MRTG's speed. Since the changes did not help much, he had decided to rewrite the time-critical sections of MRTG in C. This got me out of my 'MRTG ignorance' and I started to spend my spare time developing of MRTG-2. Soon after MRTG-2 development had begun I started to give beta copies to interested parties. In return I got many feature patches, a lot of user feedback and bug fixes. The product you are getting now wouldn't be in this state if it hadn't been for the great contributions and support I received from of many people. I would like to take this opportunity to thank them all. |
