The nntpsend.ctl file allows us to associate a (Unable to start debugging on the web server)
The nntpsend.ctl file allows us to associate a fully qualified domain name, some news feed size constraints, and a number of transmission parameters with a news feed site name. The sitename is a means of uniquely identifying a logical feed of articles. The general format of the file is: sitename:fqdn:max_size:[args] The following list describes the elements of this format: sitename The sitename as supplied in the newsfeeds file fqdn The fully qualified domain name of the news server to which we will be feeding the news articles max_size The maximum volume of news to feed in any single transfer args Additional arguments to pass to the innxmit command Our sample configuration requires a very simple nntpsend.ctl file. We have only one news feed. We’ll restrict the feed to a maximum of 2 MB of traffic and we’ll pass an argument to the innxmit that sets a 3-minute (180 second) timeout. If we were a larger site and had many news feeds, we’d simply create new entries for each new feed site that looked much the same as this one: # /etc/news/nntpsend.ctl # gmarxu:news.groucho.edu:2m:-t 180 # Controlling Newsreader Access Not so many years ago, it was common for organizations to provide public access to their news servers. Today it is difficult to locate public news servers; most organizations carefully control who has access to their servers, typically restricting access to users supported on their network. INN provides configuration files to control this access. The incoming.conf file We mentioned in our introduction to INN that it achieves some of its efficiency and size by separating the news feed mechanism from the newsreading mechanism. The /etc/news/incoming.conf file is where you specify which hosts will be feeding you news using the NNTP protocol, as well as where you define some parameters that control the way articles are fed to you from these hosts. Any host not listed in this file that connects to the news socket will not be handled by the innd daemon; instead, it will be handled by the nnrpd daemon. The /etc/news/incoming.conf file syntax is very simple, but it takes a moment to come to terms with. Three types of valid entries are allowed: key/value pairs, which are how you specify attributes and their values; peers, which is how you specify the name of a host allowed to send articles to us using NNTP; and groups, a means of applying key/value pairs to groups of peers. Key/value pairs can have three different types of scope. Global pairs apply to every peer defined in the file. Group pairs apply to all peers defined within that group. Peer pairs apply only to that one peer. Specific definitions override less specific ones: therefore, peer definitions override group definitions, which in turn override global pairs. Curly brace characters ({}) are used to delimit the start and end of the group and peer specifications. The # character marks the rest of the line it appears on as a comment. Key/value pairs are separated by the colon character and appear one to a line. A number of different keys may be specified. The more common and useful are: hostname This key specifies a comma-separated list of fully qualifed names or IP addresses of the peers that we’ll allow to send us articles. If this key is not supplied, the hostname defaults to the label of the peer.
