I'm writing an iptables Bash script, and I can't figure out why I get the below error:



Variables



iptables=/sbin/iptables
internet_int=ens33
lan_int=ens37
lan_addr=172.16.30.0/24


Rule



#lan -> internet HTTP (80/tcp)
$iptables -A FORWARD -p TCP -i $lan_int -s $lan_addr --sport 1024:65535 -o $internet_int -m multiport --dports 80,443 -m state --state NEW -j ACCEPT


Problem



Bad argument `172.16.30.0/24'



networking bash iptables firewall

  • The only thing I can think of is line termination. Could there be a carriage return and line feed character at the end of the line (dos type) instead of just unix type line termination, line feed?

pylint3 and pip3 broken

Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I have tried sudo apt remove --purge on various packages. I get the same when I reinstall. I have also tried reinstall using aptitude. This does not work. My current workaround is to run pylint3 as root, which works, but is bad practice. pip3 $ pip3 Traceback (most recent call last): File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored __import__(vendored_name, globals(), locals(), level=0) ImportError: No module named 'pip._vendor.pkg_resources' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/bin/pip3", line 9, in <module> from pip import main File "/usr/lib/python3/dist-packages/pip/__init__.py", line 13, in <module> from pip.exceptions import InstallationError, CommandError, PipError File "/usr/lib/python3/dist-packages/pip/exceptions.py", line 6, ...

How to enroll fingerprints to Ubuntu 17.10 with VFS491

Image
Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
