[nrz123]

scapy version is 2.4.3
python version is 3.7.5

my os message

# cat /proc/version
Linux version 3.18.66-perf+ (OnePlus@ubuntu-209) (gcc version 4.9.x 20150123 (prerelease) (GCC) ) #1 SMP PREEMPT Thu Jun 21 18:18:35 CST 2018

And Libpcap and tcpdump are already installed

There is no error prompt at runtime, but my scapy cannot send any packets, and the following error will be reported at startup

when i read the code,i find the class DADict is build from the file /etc/protocols,but the android system has no the file,is the file necessary？

[guedou]

I don't know if Scapt is supposed to work on Androd. PR #2324 fix the issue with the DADict error.

[nrz123]

now i can send packets,because there is no default route in my system,it is ok when i use the appoint route

[nrz123]

think you.i think it is ok run on android now,there is no problem

[p-l-]

Thanks!

No

Does this error still exist, if you execute scapy with root?
