Enabling IP Filtering
See the following example command for IP filtering setup.
See "Using RACADM Remotely" on page 110 for more information about
RACADM and RACADM commands.
NOTE: The following RACADM commands block all IP addresses except
192.168.0.57)
To restrict the login to a single IP address (for example, 192.168.0.57), use the
full mask, as shown in the following sectio:
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeEnable 1
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeAddr 192.168.0.57
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeMask 255.255.255.255
To restrict logins to a small set of four adjacent IP addresses (for example,
192.168.0.212 through 192.168.0.215), select all but the lowest two bits in the
mask, as shown in the following section:
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeEnable 1
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeAddr 192.168.0.212
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeMask 255.255.255.252
cfgRacTuneIpRangeMask Defines the significant bit positions in the IP address.
The subnet mask should be in the form of a netmask,
where the more significant bits are all 1’s with a single
transition to all zeros in the lower-order bits.
