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:
Template:Board$ which netstat | xargs ls -la /bin/netstat -> /bin/busybox.nosuid
3.2. Using the STM32MPU Embedded Software distribution for Android™[edit | edit source]
4. Getting started[edit | edit source]
Here are basic commands to start with netstat:
- Display kernel routing information
Template:Board$ 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 eth0 10.99.0.0 0.0.0.0 255.255.252.0 U 0 0 0 eth0 10.99.3.254 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
- List out listening-only connections
Template:Board$ netstat -tnl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:19999 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:5355 0.0.0.0:* LISTEN tcp 0 0 10.99.1.237:53 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:953 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:1534 0.0.0.0:* LISTEN tcp 0 0 :::19999 :::* LISTEN tcp 0 0 :::5355 :::* LISTEN tcp 0 0 :::53 :::* LISTEN tcp 0 0 :::22 :::* LISTEN
