Hello
I has use follow script to get new pppoe ip address.

#!/bin/sh

# 設定 PPPoE 介面名稱 (請確認 pfSense 上的名稱，可能是 pppoe0)
PPPOE_IF="pppoe0"

# 設定紀錄檔
IP_FILE="/root/current_pppoe_ip.txt"
LOG_FILE="/root/ip_change.log"

# 取得 PPPoE 的外部 IP
CURRENT_IP=$(ifconfig $PPPOE_IF | grep 'inet ' | awk '{print $2}')

# 確保有抓到 IP，否則跳出
if [ -z "$CURRENT_IP" ]; then
    echo "$(date) - Failed to get PPPoE IP" >> "$LOG_FILE"
    exit 1
fi

# 如果檔案不存在，則建立它
if [ ! -f "$IP_FILE" ]; then
    echo "$CURRENT_IP" > "$IP_FILE"
fi

# 讀取上次的 IP
LAST_IP=$(cat "$IP_FILE")

# 檢查 IP 是否變更
if [ "$CURRENT_IP" != "$LAST_IP" ]; then
    # 記錄變更
    echo "$(date) - IP changed from $LAST_IP to $CURRENT_IP" >> "$LOG_FILE"

    # 使用 pfSense 設定的通知 Email 發送通知
    echo "New PPPoE IP: $CURRENT_IP (Previous: $LAST_IP)" | /usr/local/bin/mail.php -s "pfSense PPPoE IP Change Alert"

    # 更新紀錄檔
    echo "$CURRENT_IP" > "$IP_FILE"
fi

I use follow script to send mail to my email.

echo "New PPPoE IP: $CURRENT_IP (Previous: $LAST_IP)" | /usr/local/bin/mail.php -s "pfSense PPPoE IP Change Alert"

But I got mail have no subject.Have any error?

@akong77 said in Use mail.php send mail but no subject.:

But I got mail have no subject.Have any error?

The PHP manual for getopt states:

"Note: Optional values do not accept " " (space) as a separator."

And in the code "getopt("s::");" means '-s' is an optional value and there can't be a space between '-s' and "pfSense PPPoE IP Change Alert":

/usr/local/bin/mail.php -s"pfSense PPPoE IP Change Alert"
