Note:

There is a very useful tools collection available, called usb-tools Running Raspbian from USB Devices : Made Easy which contains four very nice tools called usb-boot, sdc-boot, mbr2gpt and set-partuuid.

raspberryTools

Collection of some useful tools for Raspberry Pi. For sample outputs of the tools click the links.

1. raspiNetInfo.sh - Collect network information for people who want to help in network problem determination and test for common network configuration errors

2. checkWLANAndRestart.sh - Check on regular base for WLAN connection and either restart network interface or reboot Raspberry if there is no connection

3. checkThrottled.sh - Check Raspberry throttled bits with vcgencmd get_throttled and display their meaning if throtteling happened since boot or since last script invocation

4. testCPUTemperature.sh - Generates 100% CPU load on a Raspberry and monitors the CPU temperature. Useful to test the effectiveness of a heat sink and/or fan.

5. retrieveTerrabytesWritten.sh - Either retrieves the Total Bytes Written of all existing SSDs on the system or a specific SSD. Helps to get an idea when the SSD will reach it's end of life.

6. retrieveLifetimeWrites.sh - Either retrieves the LifetimeWrites of one or all existing ext2/ext3 and ext4 partitions. Helps to get an idea when the SD card or disk will reach it's end of life.

7. findRaspis.sh - Scan the local net for Raspberries and print the IPs, macs and hostnames sorted by IP

8. smsRelay.py - Receives all SMS and forwards them to an eMail. UMTS stick and python2 required

9. checkPARTUUIDsInDDImage.sh - Retrieve PARTUUIDs of Raspberry dd Backup image partitions /boot and / and check if they match in /boot/cmdline.txt and /etc/fstab

10. syncUUIDs.sh - Update /boot/cmdline.txt and /etc/fstab on a device with the UUIDs or PARTUUIDs used on the device. Useful when an image was cloned on another device.

smsRelay.py

Sample eMail relayed for a *ping SMS

Dear SMSRelayUser

I just received following SMS from +4947114712 for +4947144715 which I forward to you:

--- START SMS ---
*ping
---  END SMS  ---

Hope you enjoy my service.

Regards

Your SMS relay server on smsrelay.dummy.com

raspiNetInfo.sh

Code

Tests executed:

1. IP assigned?
2. ping of IP in internet possible?
3. ping of hostname in internet possible?
4. default gateway defined?
5. nameserver defined in /etc/resolv.conf
6. ssid found with iwlist scan?
7. ssid conforms to IEEE 802.11?

Sensitive information like external IPs, MAC addresses, SSIDs and keys in config files are masqueraded.
