There were many ufw block logs in syslog, ufw.log and messages under /var/log/
,like as
Apr 15 16:29:05 raspberrypi kernel: [2831949.081700] [UFW BLOCK] IN=wlan0 OUT= MAC=xxxxxxxxxxxxxxxx SRC=IP address of router DST=224.0.0.1 LEN=28 TOS=0x00 PREC=0xC0 TTL=1 ID=28502 PROTO=2
Work around:
$ sudo ufw allow in from ‘IP address of router’ to 224.0.0.1
or
$ sudo ufw block in from ‘IP address of router’ to 224.0.0.1
Another garbage was like as
Apr 15 16:41:44 raspberrypi rsyslogd-2007: action ‘action 18’ suspended, next retry bla bla bla
Work around:
$ sudo nano /etc/rsyslog.conf
Comment out of rear part such as
#daemon.;mail.;\
#news.err;\
#.=debug;.=info;\
#.=notice;.=warn |/dev/xconsole
then reboot
