Description Pavel Zhukov 2019-06-27 11:39:58 UTC 
This bug was initially created as a copy of Bug #1724416

I am copying this bug because: 



Description of problem:
In this format:  
echo ncat --sctp -l 127.0.0.1 | bash
ncat no output for sctp, but tcp/udp has

Version-Release number of selected component (if applicable):
nmap-ncat-7.70-4.el8.x86_64
nmap-ncat-6.40-19.el7.x86_64
Both exists on RHEL7 and RHEL8

How reproducible:
always

Steps to Reproduce:
1.
# echo ncat -l 127.0.0.1 2000 |bash
abc
# echo ncat -u -l 127.0.0.1 2000 |bash
abc
# echo ncat --sctp -l 127.0.0.1 2000 |bash
#
Get nothing here!

2.
At another terminal
# ncat  127.0.0.1 2000 <<<'abc'
# ncat -u 127.0.0.1 2000 <<<'abc'
# ncat --sctp 127.0.0.1 2000 <<<'abc'

3.

Actual results:
