Description Jaroslav Škarvada 2018-10-20 19:47:34 UTC 
Description of problem:
trafgen --in - tries to read file named '-', not the stdin.

Version-Release number of selected component (if applicable):
netsniff-ng-0.6.4-1.fc27.x86_64

How reproducible:
Always

Steps to Reproduce:
1. trafgen -e | trafgen --in - --out wlan0 --num 1 --cpp
2.
3.

Actual results:
Cannot access -: No such file or directory!

Expected results:
Packet sent.

Additional info:
From the manual page:
   -i <cfg|pcap|->, -c <cfg|->, --in <cfg|pcap|->, --conf <cfg|->
       Defines  the  input  configuration  file that can either be passed as a
       normal plain text file or via stdin (''-'').
...
   trafgen -e | trafgen -i - -o lo --cpp -n 1
       This  is  an  example  where we send one packet of the built-in example
       through the loopback device. The example configuration  is  passed  via
       stdin  and also through the C preprocessor before trafgen's packet com‐
       piler will see it.

And it's the same:
# trafgen -e | trafgen -i - -o wlan0 --cpp -n 1
Cannot access -: No such file or directory!

Although the following works:
# trafgen -e > tmp
# trafgen -i tmp -o wlan0 --cpp -n 1
