On Linux systems, unless you make network connection changes persistent, a system reboot
resets the network connection changes and loses the host-to-radio connection. To retain the
host-to-radio connection after a computer reboot, make the network connection changes to the
host computer persistent by making these changes in the
/etc/network/interfaces
/etc/sysctl.conf
, and
/etc/security/limits.conf
files.
Edit /etc/network/interfaces
to define settings for
eth1
. Use an IP address on the same subnet as your radio (that is,
the same first three octets match those of your radio) and a unique value for the fourth
octet. For more information, see Check Subnet Values on Host and Radio.
auto eth1 iface eth1 inet static address 192.168.30.1 netmask 255.255.255.0
Edit /etc/sysctl.conf
to add lines defining these settings for
net.core.rmem_max
and
net.core.wmem_max
.
net.core.rmem_max=50000000 net.core.wmem_max=33554432
To define the maximum real-time scheduling priority rtprio
, edit
/etc/security/limits.conf
and add this line. Use your group name in
place of GROUP
.
@GROUP - rtprio 99
