RESTARTDNS(8) RESTARTDNS(8)
NAME
restartdns - restart dns and mail problem report
SYNOPSIS
restartdns [ -f ]
DESCRIPTION
Restartdns automates restarting dns (see ndb(8)) safely and
emailing a problem report. You must be the hostowner to run
it. Typically restartdns is run from a cron job. With no
arguments, dns is restarted if there are broken dns pro-
cesses or processes in “query lock wait” state. In this
case a snapshot of all dns processes is taken and saved to
/n/other/user/dnssnap/host.pid.unixtime and notification
email is sent. The -f flag forces a restart.
The script itself contains configuration information such as
the list of legal host and the recipients of notification
email.
In Athens, the typical solution is to run restartdns on the
dns server, currently atlas, as the hostowner, currently
dennis.

BUGS
Due to namespace issues, drawterm(8) users of the restarted
system will need to log back in to get proper name resolu-
tion.
