Linux pc (arch) as slave to synology NAS that's connected to a UPS with USB

My synology NAS is connected to my UPS with USB. I want my linux pc to listen for UPS events and shut down when the power is low.

Step 1 - Set up UPS daemon the on the synology nas

192.168.1.148 is the IP of my PC.

Step 2  - Install network-ups-tools

https://aur4.archlinux.org/packages/network-ups-tools/

In my case it was
$aura -A network-ups-tools


Step 3 - Configure network ups tools client.

First I got the password from the synology ups daemon.
 $ ssh root@nas1
$ DS212J> cat /usr/syno/etc/ups/upsd.users

In my case it was:

[monuser]
password = secret
upsmon master

Second add the credentials to /etc/ups/upsmon.conf

For me it ended up being

MONITOR ups@192.168.1.69:3493 1 monuser secret slave

Step 4 - Enable the nut-monitor

sudo systemctl daemon-reload
sudo systemctl enable nut-monitor
sudo systemctl start nut-monitor

Step 5 - Test

$ sudo systemctl status nut-monitor

Dec 08 20:01:31 buggle upsmon[17335]: UPS ups@192.168.1.69:3493 on battery

Dec 08 20:02:01 buggle upsmon[17335]: UPS ups@192.168.1.69:3493 on line power

Dec 08 20:04:41 buggle upsmon[17335]: UPS ups@192.168.1.69:3493 battery is low

Step 6 - WalNUT

I installed https://github.com/zykh/walNUT to get some status in gnome shell.

1.) mkdir ~/.local/share/gnome-shell/extensions
2.) cd ~/.local/share/gnome-shell/extensions3.) git clone --depth 1 https://github.com/zykh/walNUT.git walnut@networkupstools
4.) glib-compile-schemas walnut@networkupstools/schemas/
5.) alt+f2 r (restart shell)
6.) Use gnome web browser to go to extensions.gnome.org
7.) Enable the extension.
8.) Click the magnifying glass and put in 192.168.1.69:3493 (ip of nas).

Reverse proxy for sonarr

First, on my home PC which is hosting sonarr - I'll restrict access to PCs on my LAN and the VPS.

iptables -I INPUT -p tcp -s VPS_IP --dport 8989 -j ACCEPT
iptables -I INPUT -p tcp -s 192.168.1.0/24 --dport 8989 -j ACCEPT
iptables -I INPUT -p tcp -s 127.0.0.1 --dport 8989 -j ACCEPT
iptables -I INPUT -p tcp -s 0.0.0.0/0 --dport 8989 -j DROP

Forward 8989 to PC running sonarr in router.

On vps in apache default site:

ProxyPreserveHost Off
ProxyPass /sonarr http://HOME_PC:8989/sonarr
ProxyPassReverse /sonarr http://HOME_PC:8989/sonarr

Also had to set settings->general-> URL Base in sonarr.

Make sure to enable authentication, either via sonarr or apache. I used form login.

<Proxy z>
AuthFormProvider file
    AuthType form
    AuthName "Login Required"
    Session Off
    SessionCookieName session path=/
    require valid-user
  # This is the login page
   ErrorDocument 401 /auth.html
           # This is the file containing users login data
   AuthUserFile /etc/apache2/.htpasswd
</Proxy>

Configuring new VPS.

Login to the server (via ssh).

$ ssh root@*.*.*.*

root@ubuntu:~# w

I want to create another user.

root@ubuntu:~# adduser youri

Make sure I can login as youri. 

 $ ssh youri@*.*.*.*

Escalate to root:

youri@ubuntu:~$ su root
Password: 

I want to disable root ssh login.

#PermitRootLogin no in /etc/ssh/sshd_config and service ssh restart

Logging as root says: Permission denied, please try again

Now I want to transfer my keys.

 $ ssh-copy-id  youri@*.*.*.*

spits out

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: WARNING: All keys were skipped because they already exist on the remote system.

but after ssh-add ~/.ssh/id_rsa it worked and copied the key.

Ssh in again and passwordless login is working. 

Now I want to disable password logins altogether.

PasswordAuthentication no in /etc/ssh/sshd_config and service ssh restart

Add my user to sudoers:

root@ubuntu:/home/youri# usermod -a -G sudo youri

Set.

VirtualBox virtual serial port Windows Guest to linux host.

1.) Select "Enable Serial Port"
2.) Port mode: Host Pipe
3.) Create Pipe Checked.
4.) Port/File Path: /tmp/vboxCOM'

Now the port shows up windows.

My version of netcat allows connecting to sockets.

extra/gnu-netcat 0.7.1-5 [installed]

nc -U /tmp/vboxCOM

To test sending data over the socket with bash:

function sendData()
{
    nc -U /tmp/vboxCOM <<< $(echo -en "\x1B$*\xD")
}
echo "Sending ST"
sendData "ST"

With python

#!/usr/bin/env python

import socket
import os, os.path
import time 

socketLocation = '/tmp/vboxCOM' 

print("Connecting...")
s = socket.socket(socket.AF_UNIX)
s.settimeout(1) # 1 second timeout, after all it should be instant because its local
s.connect(socketLocation)

Android 4.4 trying to resolve local domains with dhcp server on server 2003.

My android 4.4 device would not resolve local domains.

Ex:
sv00004 - could not resolve
sv00004.blah.com - resolved.

Solution:
* start->-run-> mmc
* Add/remove snap in-> DHCP
* Right click DHCP "Add server"
* Select the DHCP server.
* Expand to server options.
* Right click server options

I added my two DNS servers to "006 DNS Servers" and my domain blah.com to "015 DNS Domain Name".

Seems to resolve fine now - at least from chrome.

VB.net defeat simple padding obfuscation

There is an applicationthat obfuscates a serial number by padding each character. Here is a de-obfuscator I made.

First: define the array with all the characters the algorithm uses:






    Public charArray() As Char = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9", _
                           "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", _
                           "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", _
                           "V", "W", "X", "Y", "Z"}

Function that will deobfuscate it.

    Private Function OffsetAChar(ByVal chartooffset As Char, ByVal offset As Integer)
        Dim posInArray As Integer = Array.IndexOf(charArray, chartooffset)
        Dim ArrayLength As Integer = charArray.Length

        If posInArray + offset = ArrayLength Then
            Return "0"
        End If

        If (posInArray + offset) <= ArrayLength And (posInArray + offset) > 0 Then
            Return charArray(posInArray + offset)
        End If

        If posInArray + offset = 0 Then
            Return 0
        End If

        If (posInArray + offset) < 0 Then
            Return charArray(ArrayLength + posInArray + offset)
        End If

        If (posInArray + offset) > ArrayLength Then
            Return charArray(Math.Abs(ArrayLength - (posInArray + offset)))
        End If

    End Function


Usage is simple:

        Dim charArray2() As Char

        Dim ArraySTring As String = txtDecode.Text
        ArraySTring = ArraySTring.Replace("-", "")
        charArray2 = ArraySTring

       txtCodeDecoded.Text += OffsetAChar(charArray2(0), -19).ToString.ToUpper


Figuring out the offset of two letters


    Public Function OffsetFinder(ByVal letter1 As Char, ByVal letter2 As Char)

        Dim CharPos1 = Array.IndexOf(charArray, letter1)
        Dim CharPos2 = Array.IndexOf(charArray, letter2)
        Return CharPos2 - CharPos1

    End Function

VB.net 2010 run an app, activate it, and send keys.

This isn't an elegant way to do it, but it works for me. It runs a program, sends alt+h, a, tab, then ctrl+c to copy text to a clipboard and puts the contents of the clipboard into a textbox.

In sendkeys:
 % = alt
vbTab = tab
^ = crl
{escape} = ESC

Imports System.Threading

Dim pInfo As ProcessStartInfo = New ProcessStartInfo("C:\Program Files (x86)\CustomApp\Bin\customapp.exe")

      pInfo.WindowStyle = ProcessWindowStyle.Maximized
        Process.Start(pInfo)
        Thread.Sleep(3000)

AppActivate("CustomApp 1.1.5")


        System.Windows.Forms.SendKeys.SendWait("%")
        System.Windows.Forms.SendKeys.SendWait("h")
        System.Windows.Forms.SendKeys.SendWait("a")
        System.Windows.Forms.SendKeys.SendWait(vbTab)
        System.Windows.Forms.SendKeys.SendWait("^c")
        TextBox2.Text = (TextBox1.Text & " : " & Clipboard.GetText & vbCr)

        System.Windows.Forms.SendKeys.SendWait("{escape}")
        System.Windows.Forms.SendKeys.SendWait("%")
        System.Windows.Forms.SendKeys.SendWait("f")
        System.Windows.Forms.SendKeys.SendWait("q")

Trying to play GTA vice city under linux with wine.

First I need to install wine:

[youri@slavluv Downloads]$ sudo pacman -S wine

Now to configure wine and create all the folders, and it also installs gecko packages. In config I added drive D: as /tmp/CD

[youri@slavluv Downloads]$ winecfg

Make the folder in CD in tmp and mount the iso. "-o loop" (modprobe loop if it's not loaded)

[youri@slavluv tmp]$ mkdir CD
[youri@slavluv tmp]$ sudo mount -o loop /home/youri/Downloads/Grand\ Theft\ Auto\ Vice\ City\ -\ PC/GTA_Vice_City.iso CD/

Run the setup:

[youri@slavluv tmp]$ wine CD/setup.exe




Went through install (did not choose to use radio stations)

Using the no-cd crack (I have the cd but not cd-rom drive, so I have to download it, it's not illegal if you have the licensed CD)

[youri@slavluv Grand Theft Auto Vice City - PC]$ cp -f Crack/gta-vc.exe /home/youri/.wine/drive_c/Program\ Files/Rockstar\ Games/Grand\ Theft\ Auto\ Vice\ City/


Now I went to install directory ( /home/youri/.wine/drive_c/Program Files/Rockstar Games/Grand Theft Auto Vice City ) and ran wine gta-vc.exe


It messed up my screen/didn't work.

Mounting the play CD the same way I did the install CD loaded the game. All the textures are blocky though. Probably would work fine at this point for someone with a decent video card..

Disabling "Allow pixel shader" in wine settings  fixes the blockiness. Game is still slow though.

lighttpd fastcgi issues

Suddenly "mod_fastcgi" being enabled in "server.modules" for lighttpd is causing problems.

 2011-04-21 19:30:58: (log.c.166) server started
2011-04-21 19:30:58: (mod_fastcgi.c.978) bind failed for: unix:/var/run/lighttpd/php-fastcgi.socket-0 Permission denied
2011-04-21 19:30:58: (mod_fastcgi.c.1399) [ERROR]: spawning fcgi failed.
2011-04-21 19:30:58: (server.c.938) Configuration of plugins failed. Going down.

Fix:

[youri@nemesis run]$ sudo gpasswd -a youri http
Password:
Adding user youri to group http

Or I should maybe make lighttpd run as http user again.

Mapping the cell locations from an iphone db on google maps

IOs stores the GPS locations of towers it connects to in this file:

/var/root/Library/Cache/locationd/consolidated.db

It's an sqlite3 file... So here is a script to pull the longtitude and lattitudes and turn them into a simple KML file.

#/bin/bash

#this is the KML heading
echo '<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">
<Document>

  <name>youri</name>'
 
#pull the longitude and latitude from sqlite3
for i in $(sqlite3 consolidated.db 'select longitude,latitude from celllocation';)
do coordinate=$(echo $i | sed 's/|/,/g')



echo '<Placemark><name>'$coordinate'</name><Point><coordinates>'$coordinate',0</coordinates></Point></Placemark>'
done;

echo '</Document></kml>'

I added this to my lighttpd.conf and restarted it.

  ".kml"       =>      "application/vnd.google-earth.kml+xml",

Then it's just a matter of passing the kml file to google maps..

http://maps.google.com/maps?q=http://$yourserver/output.kml

I noticed a bunch of towers I never connected to  (far away places) so there are some problems with this.

Gnome-shell annoying bug.

Accidentally hitting the print screen button (which I do a lot because of this stupid keyboard) I get an annoying popup:

Text was empty (or contained only whitespace)

and in /.xsession-errors

Window manager warning: Error on command 33 "": Text was empty (or contained only whitespace)

Went to system settings - > keyboard -> shortcuts and disabled the printscreen shortcut for now.

Update: removing ~/.gconf and ~/.gnome* fixes this.
