Welcome to the new world for you FIDONet. In this tutorial you will learn Of course, not once, about many subtleties work in this exciting global network, learn how to navigate the dizzying jargon of local residents and deliver the rest of the network members to answer on the very same questions that a person sets first came to FIDONet. This article contains information that gleaned by the author from various sources. I understand that you can not grasp the immensity and therefore never sought tell the reader all the details or an issue, particularly technical. If you need more detailed information on technical issues, you can refer to the standards of network FIDONet, are available at most stations network, or seek advice from a conference SU.CHAINIK (for simple questions FIDONet), SU.MAILER (for questions about the mailers and the general discussion of their virtual benefits), and SU.FIDOTECH (questions and responses of FTN-technology). What is FIDONet? Formally FIDONet represents global non-profit information network covering the entire civilized world. In fact FIDONet - a unique opportunity to socialize with people you can never see personally, to make new friends, find advice on virtually any subject, to find skilled workers and so on. The main advantage is its FIDONet free for network members. As a member you will be paying FIDONet only its own costs of telephone calls and not pay a certain amount of kilobytes received and transmitted information. In fact, in foreign countries, where telephone companies use hourly rates, you can take a certain amount for the transfer of your Personal Network mail, newsgroups but remain free. However FIDONet - a non-profit network, that is, it is forbidden any commercial activity (except in specifically designated newsgroups). In our troubled country FIDO one of the few networks whose services meet the modest capabilities of pocket ordinary programmer. Internet, which enjoys a well-deserved popular with foreign users, not gained fame in Russia, being represented only by commercial network Relcom. Few FTP-servers in our country are protected better than pantries Gokhran, and passwords, and even telephones are known only "Dedications". Most likely, your acquaintance with the world begin to use FIDONet numerous BBS, scattered throughout the the country from Moscow to Chukotka. However, remember that the station FIDONet may not have the BBS, while BBS can not be a station FIDONet. Possibilities BBS systems and the fundamentals of communicating with them are set out in other reference materials, of which I can mention "Memo teapot FIDONet "Genes Ivanov and Russian documentation for the user BBS system-based Maximus. Learn a little about style communication FIDONet, learn some jargon and terms, you can decide for yourself, it is worth Do you go to the next stage of work network - to address the subscriber network (Points). Network structure. Network address. Perhaps because FIDONet was created as a nonprofit network, it has a hierarchical tree structure. Network structure defines the rules for transmission mail between stations subordinate units, as well as people responsible for implementing a network of various functions (coordinator). The main document describing the structure of FIDONet is a list of nodes (nodelist, nodelist from England. nodelist). There are several such lists - global list, usually called the world nodelist, as well as smaller lists for specific geographic regions. World nodelist contains the network addresses phone numbers, names and titles of the operators stations for all nodes FIDONet. It is composed of several segments, which are responsible for the compilation of the coordinators at least major items of the network. Official publication nodelista published twice a year, all the rest of the changes in the network structure recorded in the files changes (nodediffah, difah, nodediff), who with the help of special programs are made in the nodelist each station independently. The largest unit of division FIDONet a zone (Zone). Russia enters the second zone (Europe, etc.), USA are in the first zone. A detailed description of the numbers of zones can be found in the world nodelist. The zone has a coordinator (Zone Coordinator, ZC), Coordinator Questions ehokonferentsy (Zone EchoMail Coordinator, ZEC), etc. The zone generally has its own Gates (Gates, gate) for sending mail other areas of the network. Each zone has its own a list of sites included in world nodelist as one of the segments. Node list Zone 2 currently referred to as the Z2-LIST. Nodelist file to Zone 2 are called Z2-DIFF. File extensions Z2-DIFF numeric and characterize the current number of the day (Ie the date when this file has been created coordinator.) From the beginning of the year. Since the nodelist is very large, it is usually sent in archives. In this case, required to distinguish packed sheet of unpacked to make sure we do not try to compile the packed version. To do this, use another extension File (. Zxx) where xx is the last digits day. The following units of the network is a division of the region (Region). Russia is in Region 50 (usually denoted as R50). The region is reflected in the network address, but, unlike the area and other units of the division is not included in the address as an independent variable. Each region has its coordinators and their zonal nodelist segment, which is the regional coordinator (RC, Regional Coordinator, R50C in the case of Russia). In addition to the RC has more REC (Regional EchoMail Coordinator) and other coordinators. The basic unit of territorial division is FIDONet Network (Net). Network is characterized by a unique number within the zone, and contains a number of the region to which the network belongs. Network number is included in the network address as a separate field, while as the number of the region form the first two digits of the network (for the 50 all network have numbers 50xx). The Network also has its focal point (NC, Network Coordinator) and co-ordinator on echomail (NEC, Network EchoMail Coordinator). Network has its own segment in the nodelist in the region, and, moreover, list of subscribers (points, points of Eng. point), usually called pointlist. Points are not formal members of FIDONet, the subtleties of this issue are discussed below. Types of network stations In this part of the word "network" will not understand the whole global network as a whole, only part of it in the sense that it was defined above. The main station is a network host (Host), which was originally intended serve as a gateway for communication network with the outside world. However, as the network grows and increasing workload, such a scheme has ceased to justify itself. The host network is zero node of the network, and is excreted in nodelist word Host. Following the description of Host is a list of stations in this network. In addition to the host on the network is allocated a number stations, which are called hubs (Hub). Hubs unite with each other in the ring, and the remaining station network broadcast all mail for other stations through a dedicated their hub. Hubs identified in the nodelist word Hub, for followed by a list of stations transmitting your outgoing mail at the hub. In heavily loaded networks, which is to Example 5020 (Moscow, Russia) was isolated as hubs in the second level (Second Level Hub). In this case, the load is distributed between the hubs and accelerates the distribution of mail. The basic unit is a network node (Node, node, node). Node is a member of FIDONet and its rights and obligations are governed by the Charter FIDONet. Charter FIDONet called FIDONet Policy (policy). Currently a version POLICY 4.1. Host receives mail from other network nodes and network subscribers. Each node has a certain amount of their abenentov (points given node). Node independently determines for itself the order of transmission network mail message to the recipient (ie, can carry out both direct connections and communicate through the hub / host / gateway). In weighted networks are defined by special global circuit routing (routing, routing), designed to facilitate the identification of transmission of letters and accelerate their passage. The smallest unit of a network is subscriber network (Point, point). Point is stable direct communication with the host, which he is a subscriber. In this case, corresponding node is called a boss nodom (Boss, boss-node) for this Point. Under the current FIDONet Policy Point is not a formal member of the network and can not to direct transmission network mail recipient of the letter. This limitation is due the fact that the direct transfer operator boss-node can not control the content of letters from Point, and therefore not can prevent the transmission of commercial information on the network. Since FIDONet built on hierarchical principle, the mail is transmitted from station to station until it reaches the lowest parts of the network. Parent links of the network to accept mail from the lower and transmit it even higher, as well as take mail from a parent to subordinate units. Chain of command determines direction of the call - the caller node usually is inferior to the caller. With the direct connection between two nodes of parent node is called the uplink (uplink), the child - the downlink (downlink). The structure of the network address. There are several schemes for addressing the network. Some of them are outdated and so in this guide refers to only in the additional chapters. Currently the most widely used is addressing 4D and 5D (4D-addressing and 5D-addressing), ie There are four and five fields of network address. 5D-Addressing allows you to organize exchanges between the various global networks, and is more progressive. 4D-mail address. The main field 4D-address: Zone: Net / Node.Point Here Zone - the zone number, Net - number of networks within the area (in this field is in particular the number of the region), Node - Number Site, Point - Point number node. For nodes Network Field Point is senseless, therefore, when addressing the node field Point of zero is assumed (ex: 2:5020 / 54.0) or even omitted (if there is 3D-Addressing) (ex: 2:5020 / 54). 5D-mail address. 5D-addresses stored in two forms: Zone: Net / Node.Point @ Domain Domain # Zone: Net / Node.Point Field values are the same. Field domain defines the symbolic name of the network. For FIDONet used domain fidonet (ex: 2:5020 / 54.46 @ fidonet). Other networks may have their own domains, ie can be distinguished address in one network from another. It should be remembered that certain addressing schemes are supported limited range of software products, used in the network FIDONet. Before you decide what address to apply, you must read the manual on the software used. The main address of the station network is called the address of its principal (main address) and possibly other address called AKA (from the English. Also Known As - "Also known as ..."). Flags. In the nodelist and pointlist there special field that contains the flags for this station. Flags determine the rate of and modem, the regime of the station etc. Here's a short list of flags related to the regime of the station : Flag Value CM Station clock MO Mail-Only. Missing BBS LO ListedOnly. We accept only calls from systems offer in the current nodelist. In addition to these flags, there are others, a complete list and the appointment of which you can find at the end of the current nodelist. Types of mail. Originally conceived FIDONet as a network for the exchange of personal letters. Therefore, the first type of mail FIDONet historically proved to be a network or netmeyl mail (NetMail). Letter sent to the network by mail, there is always a single copy, which moves from author to the recipient through one or more network nodes. Nodes in the network combines network mail destined for a parcel to a specific node (node group or a region) into packets that are sent Only the connection. Network-mail is analogue of the usual letters, located in envelope (ie, read it can only addressee). However, due to a total ban on the transfer of commercial information network mail system operators can view the sites through which the forwarding letter. This perusal can be carried out in order to identification of commercial information transmitted over the network. With the growth of the network, a new kind of mail - echomail or ehomeyl, EchoMail. Echomail is an analogue of Translator, in which each can accommodate letter or respond to letter to another person. Echomail usually shares at a conference on various subjects (Ehi, Echo). This letter will be sent to all stations on the network, signed on concrete board (the conference). Ehopismo There is not one, but a few hundred or even thousands of copies. Remember about this when writing letters to echomail. As a rule, passed ehopismo in packaged form (ie, packets of letters archiver packaged type ZIP, ARJ and etc.). In this case echomail called arkmeylom (ArcMail). Files containing echomail have hex names corresponding to the network address station and expand on weekdays and file number (ie six files on Monday will have the extension. MO5). Note: despite the almost across-the use of PKZIP and ARJ, the only standard FIDONet archiver utility is ARC. Letter format. Longhand on a network FIDONet has the following fields Required completion: From: <name of the author of the letter> at To: <recipient's name> at Subj: <thread> Note that the word Subj (sabzh, sabdzh, subzh, subdzh, ...) is often used as a kind of macro for the subject line in its text.
