Produce too much log

[blckngm]

Dnsmasq logs every entry in the list every time it starts/reloads, thus created an /var/log/syslog as large as 0.5GiB on my router.

Users should be warned of this problem.

There is unfortunately no easy fix. Maybe we should contact
dnsmasq-discuss.

I use systemd's journal and it was limited by default, so I never paid attention to it. Please let me know if there is a fix and I'll update README accordingly :)

@felixonmars in fact journald will be more affected, because it shares the limit among all the logs. With syslog, it's easier to filter out and rotate dnsmasq's logs so it won't occupy too much space.

I didn't get any response from dnsmasq-discuss.

Here is how to discard these logs with rsyslog:

In /etc/rsyslog.conf prepend, or create /etc/rsyslog.d/10-dnsmasq-china-list.conf and add

:msg, contains, "using nameserver 114.114.114.114#53 for" ~

There doesn't seem to be an easy way to filter logs in journald though.

Simon Kelley has fixed it in dnsmasq(link). Closing.

Thanks for the update!
