raspberryTools

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

raspiNetInfo.sh - Collect network information for people who want to help in network problem determination and test for common network configuration errors Documentation and download link
raspiSD2USB.py - Transfer root partition to an external partition (e.g. USB stick, USB disk, ...) and modify /boot/cmdline.txt accordingly Documentation and download link
raspiSD2USB.sh - Predecessor of raspiSD2USB written in bash. Not maintained any more. Feel free to fork and open pull requests.
wlan_check.sh - Check on regular base for WLAN connection and either restart network interface or reboot Raspberry if there is no connection
check_throttled.sh - Check Raspberry throttled bits with vcgencmd get_throttled and display their meaning if throtteling happened since boot or since last script invocation
temp_test.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.
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.
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.
findRaspis.sh - Scan the local net for Raspberries and print the IPs, macs and hostnames
smsRelay.py - Receives all SMS and forwards all SMS to an eMail. UMTS stick required.

Tests executed:

IP assigned?
ping of IP in internet possible?
ping of hostname in internet possible?
default gateway defined?
nameserver defined in /etc/resolv.conf
ssid found with iwlist scan?
ssid conforms to IEEE 802.11?

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

raspiSD2USB.py

Moves the root parition to an external partition and modifies /boot/cmdline.txt accordingly. The original /boot/cmdline.txt is saved as /boot/cmdline.txt.sd just in case it's required to revert to use the SD card as root partition.
