When accessing my Linux Mint system remotely with SSH or Samba everything halts for about 20 seconds, then works again. This happens very often.
When I run the command:
# ping -i 5 -s 1 192.168.0.1 > /dev/null &
Everything runs smoothly... But if I add this line to /etc/rc.local it has no effect... This bodge job worked perfectly with CentOS.
