If somebody want to have a look into a log file before the next release, I will give a small howto.

Install sysklogd and edit config file:

Code:

sudo gainroot
apt-get install sysklogd
vi /etc/syslog.conf

comment out (to prevent fill up the root):

Code:

#*.*;auth,authpriv.none		-/var/log/syslog

add:

Code:

kern.warning			/home/user/.genwall/iptables.log

The package is uploaded to extras-devel. Added more screenshots.

To use the icon from application browser you need to have sudser installed.

Isnt it better to add a a "genwall.sudoers" in "/etc/sudoers.d/" ?
here is an example for the bnf.sudoers file

Code:

user ALL = NOPASSWD: /usr/sbin/bnf.sh

and then you can remove the sudo from the desktop file

i really dont know the different but this is what all devs doing

Great job dude

./sifo

Thank you for the hint I didn't know that. I will dig into it.

No.

Nope, if you follow sifo's first hint. Put a genwall.sudoers file into /etc/sudoers.d with content

Code:

user ALL = NOPASSWD: /usr/sbin/genwall

Code:

user ALL = NOPASSWD: /opt/genwall/bin/genwall

or whereever your binary/link lives.
And then call update 'update-sudoers' in postinstall script.
This will allow the user to execute genwall with sudo rights without entering a password. You still need to call it with sudo from desktop file as well as from command line.
Sudser just adds a * to sudoers (not my security-preferred thing, but easy for lazy) ...

Thank you to put some light in this matter. What you think about the file location? Move the binary to opt or make a symlink?

I did not take a look into your sources/binaries, but in general put all stuff to opt and just put a symlnk to /usr/sbin/genwall (so there is no 'or' in your question

Released a experimental version for N9(50). See deb in first post.

- load iptable modules and run genwall as root or developer

If somebody knows how to tweak the logging for syslog in PR1.2 let me know.
At the moment I try to figure out what is possible with N950; the stock kernel modules are poor.
