3. Installing the trace and debug tool on your target board[edit | edit source]
3.1. Using the STM32MPU Embedded Software distribution[edit | edit source]
netstat is installed by default and ready to be used with all STM32MPU Embedded Software Packages.
It comes through the busybox:
which netstat | xargs ls -la
/bin/netstat -> /bin/busybox.nosuid
3.2. Using the STM32MPU Embedded Software distribution for Android™[edit | edit source]
netstat is installed by default and ready to be used with all STM32MPU Embedded Software Packages for Android™.
It comes with the toybox:
which netstat | xargs ls -la
/system/bin/netstat -> toybox
4. Getting started[edit | edit source]
Here are basic commands to start with netstat:
- Display kernel routing information
netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 10.99.3.254 0.0.0.0 UG 0 0 0 end0
10.99.0.0 0.0.0.0 255.255.252.0 U 0 0 0 end0
10.99.3.254 0.0.0.0 255.255.255.255 UH 0 0 0 end0
- List out listening-only connections
netstat -tnl
