CONTROL.CTL(5)CONTROL.CTL(5)NAMEcontrol.ctl - specify handling of Usenet control messages
The file /var/spool/news/data/control.ctl is used to determine what
action is taken when a control message is received. It is read by the
parsecontrol script, which is called by all the control scripts. (For
an explanation of how the control scripts are invoked, see innd(8).)
The file consists of a series of lines; blank lines and lines beginning
with a number sign (``#'') are ignored. All other lines consist of
four fields separated by a colon:
The first field is the name of the message for which this line is
valid. It should be either the name of the control message, or the
word ``all'' to mean that it is valid for all messaages.
The second field is a shell-style pattern that matches the email
address of the person posting the message. (The poster's address is
first converted to lowercase.) The matching is done using the shell's
case statement; see sh (1) for details.
If the control message is ``newgroup'' or ``rmgroup'' then the third
field specifies the shell-style pattern that must match the group being
created or removed. If the control message is of a different type,
then this field is ignored.
The fourth field specifies what action to take if this line is selected
for the message. The following actions are understood:
doit The action requested by the control message should be performed.
In most cases the control script will also send mail to usenet.
If the control message has an argument, this is treated as a
``doit'' action. If no argument was given, it is treated as a
``mail'' entry. This is used in ``sendsys'' entries script so
that a site can request its own newsfeeds(5) entry by posting a
``sendsys mysite'' article. On the other hand, ``sendsys
bombs'' ask that the newsfeeds file be sent; by using ``doi‐
farg'' such messages will not be processed automatically.
The action is performed, but a log entry is written to the spec‐
ified log file, file. If file is the word ``mail'' then the
record is mailed. A null string is equivalent to /dev/null. A
pathname that starts with a slash is taken as the absolute file‐
name to use as the log. All other pathnames are written to
/var/spool/news/data/file.log. The log is written by writelog
drop No action is taken; the message is ignored.
log A one-line log notice is sent to standard error. Innd normally
directs this to the file /var/spool/news/data/errlog.
A log entry is written to the specified log file, file, which is
interpreted as described above.
mail A mail message is sent to the news administrator.
Lines are matched in order; the last match found in the file is the one
that is used. For example, with the following three lines:
A newgroup coming from ``tale'' at a UUNET machine will be honored if
it is in one the mainstream Usenet hieararchy. If ``kre'' posts a new‐
group message creating ``aus.foo'', then mail will be sent. All other
newgroup messages are ignored.
