Indeed. We got bitten by the fixing of the initial synchronisation check
when we upgraded to 4.24 last week (from 4.22). Admittedly, I should
have written the script more robustly in the first place, but... ;-)
Who wants to pay for monitoring software when a combination of ping,
netcat, cron and a few text files can do the job for free? :)
Personally, I'd much rather just have to change
nc -z ${IP} ${port} >/dev/null 2>&1
to
if [ $port -eq 25 ]; then
echo -e 'quit\n' | nc -i 2 ${IP} ${port} >/dev/null 2>&1;
else
nc -z ${IP} ${port} >/dev/null 2>&1
fi
than persuade someone else to fix their broken code. A few minutes of my
time to write and test the change, and `hey presto!', no more moaning in
the logs.
Sorry, drifted OT a tad... :)
