Ensure bcastping is disabled

中等級 1自動化aix

說明

The bcastping parameter determines whether the system responds to ICMP echo packets sent to the broadcast address. The bcastping parameter will be set to 0. This means that the system will not respond to ICMP packets sent to the broadcast address. Audit: `no -o bcastping` must report 0.

檢查方式

稽核方法: Shell 指令

shell

command -v no >/dev/null 2>&1 || exit 1; out=$(no -o bcastping 2>/dev/null) || exit 1; printf '%s\n' "$out" | sed 's/[[:blank:]]*=[[:blank:]]*/=/'

預期輸出: bcastping=0

修補方式

修補方法: 操作指南或基礎設施修補檔

no -p -o bcastping=0 (sets the running value and makes it persistent in /etc/tunables/nextboot)
