After Installing PASSWALL

1. Plug in USB Drive to the router

2. UNMOUNT THE USB DRIVE From passwall > system > mounts

3. Run commands below in openwrt remote ssh.

Partition and format the USB disk.

DISK="/dev/sda"
parted -s ${DISK} -- mklabel gpt mkpart extroot 2048s -2048s
DEVICE="${DISK}1"
mkfs.ext4 -L extroot ${DEVICE}

Configure the extroot mount entry.

eval $(block info ${DEVICE} | grep -o -e 'UUID="\S*"')

eval $(block info | grep -o -e 'MOUNT="\S*/overlay"')

uci -q delete fstab.extroot
uci set fstab.extroot="mount"
uci set fstab.extroot.uuid="${UUID}"
uci set fstab.extroot.target="${MOUNT}"
uci commit fstab

Transfer the content of the current overlay to the external drive.

mount ${DEVICE} /mnt

tar -C ${MOUNT} -cvf - . | tar -C /mnt -xf -

Configure a mount entry for the the original overlay.

DEVICE="$(block info | sed -n -e '/MOUNT="\S*\/overlay"/s/:\s.*$//p')"

uci -q delete fstab.rwm
uci set fstab.rwm="mount"
uci set fstab.rwm.device="${DEVICE}"
uci set fstab.rwm.target="/rwm"
uci commit fstab

Reboot the device to apply the changes.

reboot

Preserving opkg lists

😎Save opkg lists to /usr/lib/opkg/lists stored on the extroot, instead of in RAM. This makes package lists survive reboot and saves some RAM.

sed -i -e "/^lists_dir\s/s:/var/opkg-lists$:/usr/lib/opkg/lists:" /etc/opkg.conf
opkg update

Done !

Run this auto command (Cmmands above but automatic 😊)

rm -f passthewall.sh && wget https://raw.githubusercontent.com/ThyArt-IsMurder/passthewall/main/passthewall.sh && chmod 777 passthewall.sh && sh passthewall.sh
