6 innxbatch, sendxbatches - Send xbatched Usenet articles to a remote
7 NNTP server

10 innxbatch [-Dv] [-t timeout] [-T timeout] host file [file ...]
11 innxbatch -i [-Dv] [-t timeout] [-T timeout] host
13 sendxbatches sitename host file [file ...]
15
17 innxbatch connects to port 119 of the NNTP server at the specified
18 host, and sends it the specified xbatch files, using the XBATCH
19 extension to the NNTP protocol. These files are specified either from
20 the command line or from standard input if i is used.
21 Each file is removed after it has been successfully transferred.
23 If a communication error such as a write(2) failure, or an unexpected
25 reply from the remote server occurs, innxbatch will stop sending and
26 leave all remaining files untouched for later retry.
27 If authentication credentials are present for the remote server in the
29 passwd.nntp file in pathetc, then innxbatch will use them to
30 authenticate.
31 innxbatch does not use itself any file locking. At worst, a batch
33 could be transmitted twice in parallel by two independent invocations
34 of innxbatch. To prevent this, it should be invoked by a script run
35 out of cron(8) that uses shlock(1) to lock the host name, followed by a
36 "ctlinnd flush" command to flush the batch file. sendxbatches is such
37 a wrapper around innxbatch. It will ensure only one instance is run,
38 flush sitename (as used in the newsfeeds entry) and send to host the
39 files given as arguments.
40 As the XBATCH extension is not a standardized NNTP command, some news
42 servers do not recognize it. Instead of using innxbatch, you may
43 consider innfeed, or if that is not possible, nntpsend.
44
46 -D Prints debugging information on standard error. This will show the
47 protocol transactions between innxbatch and the NNTP server on the
48 remote host.
49 -i Reads batch file names from standard input. For each successfully
51 transmitted batch, an "OK" is printed on stdout to indicate that
52 another file name is expected.
53 -t timeout
55 Specifies a timeout in seconds on how long to try to make the
56 connection. Otherwise, innxbatch normally blocks until the
57 connection is made.
58 -T timeout
60 Specifies the total amount of time in seconds that should be
61 allowed for article transfers.
62 The default is to wait until an I/O error occurs, or all the
64 articles have been transferred. If this flag is used, the time is
65 checked just before each article is started; it will not abort a
66 transfer that is in progress.
67 -v Upon exit, innxbatch reports transfer and CPU usage statistics via
69 syslog(3). If this flag is used, they will also be printed on the
70 standard output.
71
73 A sample newsfeeds entry to produce appropriate xbatch files is:
74 nase\
76 :*\
77 :Tc,Wnb\
78 :<pathbin>/batcher -p "(<$COMPRESS in <pathlib>/innshellvars>\
79 > <pathoutgoing>/nase.\$\$)" nase.do.main
80 A sample script to invoke innxbatch(8) is:
82 #! /bin/sh
84 # Send xbatches for a site, wrapped around innxbatch.
85 if [ $# -lt 3 ]
86 then
87 echo "usage: $0 <sitename> <hostname> <xbatch file name> ..."
88 exit 1
89 fi
90 . <pathlib>/innshellvars
91 site="$1"; host="$2"; shift; shift
92 ctlinnd flush "$site" \
93 && sleep 5 \
94 && exec ${NEWSBIN}/innxbatch -v -D "$host" $*
95 You can use sendxbatches, already shipped with INN, doing locking. An
97 example of call is:
98 sendxbatches nase remote.news.server.name <pathoutgoing>/nase*
