# fix-fstab-lan.sh — 2026-09-04 牧尘指示：SMB 备份只在家庭局域网(192.168.123.11)
|
||
# 根因：fstab 把 automount 写死为 StarVPN(192.168.188.11)，导致外网也挂 SMB 传大文件 → 弱网僵死
|
||
# 修复：fstab 挂载 IP 改回局域网 192.168.123.11（保留 x-systemd.automount：
|
||
# 外网时 dual-backup.sh 先探测 123.11:445 不通即跳过，不触发挂载；
|
||
# 在家时探测通过 → 访问挂载点触发 automount 挂局域网共享）
