Gammu runonreceive 不传递变量

Question

我想将我的 Rapsberry 配置为 SMS Ping Pong 播放器。所以我安装了 gammu-smsd 并配置了 gammu-smsdrc 如下：

# Configuration file for Gammu SMS Daemon

# Gammu library configuration, see gammurc(5)
[gammu]
# Please configure this!
port = /dev/ttyUSB3
pin= 4135
connection = at
# Debugging
logformat = textall

# SMSD configuration, see gammu-smsdrc(5)
[smsd]
RunOnReceive = sudo /var/spool/gammu/receivesms.sh
service = files
pin = 4135
# Increase for debugging information
debuglevel = 1
logfile = /var/spool/gammu/gammu.log
include_smsc = 491722270333

# Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/

到目前为止，发送短信和接收短信都很好！

所以我尝试了 runonreceive 的东西。并编写了一个小脚本来获取短信发件人号码和文本。如果文本是 "ping"，gammu-smsd 应该将 pong 发送回发件人。

reveivessms.sh:

#!/bin/sh
from=$SMS_1_NUMBER
message=$SMS_1_TEXT
reply=""

if test "$message" = "Ping"; then
    reply="Pong!"
else
    reply="Y U NO PLAY PING PONG?"
fi


sudo echo "$reply" | /usr/bin/gammu-smsd-inject -c /etc/gammu-smsdrc TEXT "$from"

gammu.log 是：

嗯，没有消息回复...

所以我尝试不传递参数并将 receivesms.sh 更改为：

#!/bin/sh
sudo echo Gude Wie | /usr/bin/gammu-smsd-inject -c /etc/gammu-smsdrc TEXT 49160xxxx

一切正常。似乎传递给 receicesms.sh 的变量不起作用。但我不知道为什么？

Answer 1

问题是 sudo 不会在默认配置中保留环境变量，所以我建议您避免在脚本中使用 sudo。运行作为 root 的 SMSD 也存在潜在的安全风险，因为在 SMS 解码中出现某些错误的情况下，攻击者直接运行ning 作为 root。

因此，最好运行 SMSD 作为用户并相应地更改 /var/spool/gammu 和 modem/phone 设备的权限。

如果您坚持运行将 SMSD 设置为 root，请更改 sudo 配置以保留环境变量，请参阅 How to keep Environment Variables when Using SUDO

Answer 2

使用 gammu-smsd-inject 运行接收发送短信回复是一项任务。

对于遇到此问题的任何其他人。我通过将 gammu-smsd-inject 命令的 stdout 和 stderr 重定向到 /dev/null.

解决了这个问题

echo "This somehow works" | gammu-smsd-inject TEXT $from > /dev/null 2>&1

此致
