Safeguarding Your Adopisoft Account: Essential Security Tips

 Here at AdoPiSoft, we take the security of your accounts very seriously. To ensure the continued safe operation of your vending machines and manager accounts, we kindly ask you to follow these important security practices:

1. Unique Passwords:

Never use the same password for your Adopisoft manager account, vending machine credentials, and email address. This creates a single point of failure; if one password is compromised, both accounts are at risk.

Create strong, unique passwords for both accounts. A strong password should be at least 12 characters long and include a combination of uppercase and lowercase letters, numbers, and symbols.

These are the 3 accounts for managing adopisoft:

I. The adopisoft manager account, accessible through http://manager.adopisoft.com, acts as the central hub for managing your wifi vendo business. Here, you can create and manage user accounts, monitor sales reports, and manage machines and licenses,sub-vendo credit, and ECASH payments.

II. For individual machine control, you can access each vendo machine's local web interface through a web browser at http://10.0.0.1/admin on your local network. This interface allows you to view real-time machine status, adjust local settings, and potentially troubleshoot any connectivity issues.

III. Finally, a separate email account, accessed through your preferred email provider's webmail interface or email client, is crucial for receiving important notifications from AdoPiSoft. This could include system updates, account verification messages, license activation, revoke and license transfer, or even critical alerts about your vendo machines. Remember, the specific server details for accessing your email will depend on the email provider you use (e.g., Gmail- https://mail.google.com/mail/, Yahoo Mail - https://mail.yahoo.com/, etc.).

By effectively utilizing these three accounts, you can maintain control over your wifi vendo business, ensuring smooth operation and maximizing your profits.

2. Secure Login Practices:

Always log out of your AdoPiSoft manager account after each session or use incognito mode(CTRL+SHIFT+N in Chrome). This is especially important if you are using a public computer or a shared device.

Do not share your login credentials with anyone. This includes employees, colleagues, or anyone else.

Enable two-factor authentication (2FA) for your email account. This adds an extra layer of security by requiring a second verification code in addition to your password when logging in.

3. Public and Shared Devices:

Avoid logging in to your AdoPiSoft manager account on public computers or shared devices. If absolutely necessary, ensure you log out completely and clear your browsing history before leaving the device.

By following these simple security practices, you can help to protect your AdoPiSoft accounts and vending machines from unauthorized access.

Additional Tips:

Be cautious about clicking on suspicious links or downloading attachments from unknown senders. Phishing scams can attempt to steal your login credentials.

If you believe your password has been compromised, change it immediately for both your Adopisoft manager account and your email address.

Securing your account is a collaborative effort between you and Adopisoft. We are committed to providing a secure platform, but your active participation is crucial in safeguarding your information. By following these security best practices, you not only protect your data but also contribute to the overall security of the Adopisoft community.

Together, we can create a stronger and more secure environment for everyone.


By following these simple security practices, you can significantly reduce the risk of unauthorized access to your Adopisoft account and protect your valuable data.

If you have any questions or require further assistance with securing your accounts, please don't hesitate to contact Adopisoft support.

Thank you for your cooperation in maintaining a secure environment for everyone using Adopisoft.


Adopisoft Subvendo Credits

 Kung walang subvendo credit, lahat ng coinslot sa lahat ng interface ay makikita during insert coins, Kung may naka assign na subvendo credit naman kung ilang subvendo na may subvendo credit ang nasa isang interface, yun din lang ang makikita during insert coin, kung isa lang  automatic auto select coinslot.Yung walang credit sa specific interface na iyon ay di mo makikita at di mo na magagamit ang subvendo dahil hinaluan mo na ng may credit.

What is subvendo credit?
ang subvendo credit ay para sa mga existing coinslot na gustong maging auto select coinslot ang mga subvendo.

ang auto select coinslot ay magwowork lang kung naka separate interface ang bawat subvendo

ang subvendo ay free at magagamit mo yan kaagad kung tama ang setup and configration.

ang subvendo credit ay hindi license

ang auto select coinslot ay magwowork lang kung naka separate interface ang bawat subvendo at merong subvendo credit ang bawat subvendo sa bawat interface.

Advanced Sub Vendo Capabilities:

1. auto select coin slot if one coin slot is assigned in every interface

2. capability to have different rates in every sub vendo

3. Sub vendo credit is P399 for additional sub vendo with separate rates from the free basic version. You need to separate the sub vendo interface before you activate the advanced sub vendo on that separate interface or else you might need to buy sub vendo credits to all of your available coinslot whether its main or sub.

If your having 2 or more coinslot using the 10.0.0.1 interface, you need to buy credits to all of your availalbe coinslot or else you cannot use the rest of the coinslot whether its main os sub in that interface without assigning sub vendo credit to it

Please separate the interface and assign sub vendo credit to that interface so that your main interface is still free to use without needing a sub vendo credits

Example of Using subvendo credit:

Ex vlan22 10.0.0.1

       Subvendo Coinslot A

       Subvendo Coinslot B

     usb to lan 20.0.0.1

       subvendo coinslot C

     usb to LAN 30.0.0.1

        subvendo coinslot D

     vlan23 40.0.0.1

        subvendo coinslot E

        subvendo coinslot F

Scenario1: wala kang sub vendo credit.During insert coin lahat ng coinslot lalabas from A to F

Scenario2: may sub vendo credit ka at naka activated sa C

           Kapag sa ABDEF ka naka connect , lalabas lahat ng coinslot ABDEF except C.

           Kapag sa C ka naka connect C lang ang lalabas.

Scenario3: may sub vendo credit ka at sa coinslot E lang naka activate

           Kapag sa ABCD ka naka connect, lalabas ang coinslot ABCD.

           Kapag sa E ka naka connect, E lang ang lalabas. Yung F ay madidisable at hindi mo magagamit hanggat hindi mo linalagyan ng sub vendo credit

scenario 4 : Kapag may sub vendo credit ka at naka activate sa E at sa F, kapag kokonek sa sa ABCD, ABCD lang ang lalabas. Kapag sa E at F ka kokonek, E at F lang ang lalabas.

Configuring Network Setup of Adopisoft

 Here are possible scenarios that you can configure assuming 1 USB to LAN, 1 VLAN ID 22
1.separate network:
   USB To LAN-10.0.0.1 assuming your USB to LAN is eth1
   VLAN ID 22- 20.0.0.1
   if USB TO LAN is the main interface
or

USB to LAN - 20.0.0.1 assuming your USB to LAN is eth1
VLAN ID 22- 10.0.0.1
if VLAN ID 22 is the main interface

2.Combined network using bridge-Network bridging is a process of connecting multiple communication networks or network segments into a single, unified network.It's achieved using a network bridge, a hardware device that filters and forwards data packets based on their Media Access Control (MAC) addresses.In short 2 or more multiple network will use and joined into single network/IP.Their individual IP will be discarded.

VLAN ID 22-22.0.0.1
USB to LAN- 20.0.0.1
Bridge(br0)-10.0.0.1  is the main interface resulting from combining USB to LAN and VLAN ID 22







Let's configure the separate network where USB to LAN is the main interface:

Go to network then interface then eth1

    check enable captive portal

    set maximum hops allowed to 1

    uncheck dynamic ip address

    set static to 10.0.0.1

    set network segment to 20

    check Use System DNS Server

    Check Enable DHCP Server on this Interface

Troubleshoot Coinslot problem

 1. May credit na P1.00 pagka press ng insert coin kahit waala pang hinuhulog na coins.
Solution: May 2 slider switch sa likod ng coinslot, paki angat lang po ng sagad

With P1.00 credit everytime you press insert coin
Solution: there are 2 slider switch at the back of a coinslot. Make sure it is both switched upward.


2. Yung credit ng isang P5 na coin ay piso. Ganun din ang isang P10 na coin.
Solution: uncheck Block FAST Insert kung naka powercut setup po kayo. Ang Block Fast insert ay para sa mga naka SET PIN.

The 5 coin and the 10 coin produces 1 credit
solution: uncheck Block fast insert if your using powercut setup. Enabling Block fast insert will work only when using SET PIN.




3. Minsan may mga coins na pumasok pero hindi nagcredit. 
Solution: Try LOOP sa coinslot reading type. Mas minimize ang di nagcredit sa LOOP. From my observation and testing although depende pa rin sa coinslot.

Sometimes coins inserted doesn't credit
Solution: Try LOOP.This will minimize not credited coins.Its from my observation and testing although it depends on coin slot.

Here are more probable culprits for the unrecognized coins:

  • Dirty or faulty sensor: Dust, debris, or a malfunctioning sensor can prevent proper coin detection.
  • Loose connections: A loose wire connecting the coin slot to the machine can disrupt communication.
  • Incorrect calibration: The coin slot might be programmed to recognize specific sizes and weights, and if the calibration is off, it might reject valid coins.
  • Foreign objects: Sometimes, objects like pins or washers can get stuck in the mechanism, causing jams and disrupting coin recognition.

Here's a troubleshooting approach:

  1. Check for blockages: See if any foreign objects are stuck in the coin slot.
  2. Clean the sensor: Use a can of compressed air to gently blow out any dust or debris.
  3. Verify power supply: Ensure the coin slot is receiving the correct voltage (usually 12V DC).
4. Check Pin Assignment vs sa kung saan nakasaksak na pin sa board(the position of the wire where it is inserted on the pin. By default PIN3 for white wire and PIN5 for relay in the assignment at dapat sa PIN3 at PIN5 din sakasaksak sa board (and at the same time, it should be inserted on pin3 and pin5 of the board.
coinslot white wire - responsible for pulse reading
relay pin - responsible for blocking coinslot kapag naghulog ng coins na di pumipindot ng insert coins


5. Yung isang P5 peso coin ang reading ay P4 o kaya ang isang P10 peso coin ang reading ay P9 o kaya ang isang P20 na coin, ang reading ay 19
Solution:
By default ito ang payment portal pulse settings
1 pulse = P1.00
5 pulse = P5.00
10 pulse = P10.00
20 pulse = P20.00

Yung P20pulse for P20.00, paki lagay dahil may mga oras na ang reading ng isang P10 coins ay nagiging doble 20(dalawang P10 coins kahit isa lang P10 hinulog)

Paki lagay na rin ang mga ito kung kulang ng isa as stated on the problem above.
4 pulse = P5
9 pulse = P10
19 pulse = P20

Kung kulang ng 2 ang isang coins na hinulog paki dagdag ito:
3 pulse = P5
8 pulse = P10
18 pulse = P20


6. Kung hindi talaga nagke credit at wala ang problema sa mga nabanggit sa taas, 2 lang yan sira na ang specific pin3 ng board at pwede mo siyang ilipat sa iba. At pangalawa sira na talaga ang lahat ng pin ng board-magpalit ka na ng board.
Ito ang mga pin na pwedeng lipatan 3,5,7,11,13,15,16,18 kung di gumagamit ng CB
Kung OPI one 3,5,7 lang kung naka official Ado custom board
Kung naka RPI board ka pwede ang mga ito kung di ka gumagamit ng custom board 3,5,8,11,12,13,15,16,18,19,21,23,24,26,29,31.32,33,36,37.38,40

Fixed for ver 5.1.3 or any version with Validating machine after flash

Problem: Validating license, http request error, machine is offline, internet is down and inventory logs do not appear.


Note: This fix works only on version 5.1.3 and above not on validating license  on old version 3.xx machine,

Caused: Time and date is not synchronized and DNS is not properly configured

Solution: 

Paki edit ang laman ng timesyncd.conf at resolv.conf para mag automatic sync ang date and time.Pwede naman itama ang ang date and time manually pero malelate pa rin yan pag nag brownout/restart

Use putty terminal and follow these steps
1. Download putty in your laptop or desktop.
Download here: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
Download the 64bit if you're using 64bit and 32 bit if using 32 bit for windows system.
No laptop or desktop, don't worry you can use Termius apps on your Android phone.Here is the guide
Click this using Termius guide

2.Enable SSH on your Adopisoft admin dashboard


3. Make sure your PC is connected to  vendo machine or the portal 10.0.0.1 is accessible on your PC then open putty.


Use the following login credentials:

For other board:
user:adopisoft
pass:asdf@12345

For RPI
user:pi
pass:raspberry

For OPI5/OPI ONE/OPI PC
user:username: root
passwd: asdf@12345 or asdf@123 or Asdf@12345

For Generic machine/Ubunto server
user:adoadmin
pass:AdoPiSoft

For Ubunto Server Business OVA File for Virtual Machine
user:username: root
passwd: asdf@12345

Note: Typing password, will have no screen response. Just make sure you type it correctly then ENTER.Yung password pala wag kang magtaka kung walang lumalabas sa screen.Ganyan talaga yan di nakikita

4. Once na nakapasok, after you login type date then press ENTER


5.Double check the result. Change if the time and date is incorrect.

To change your time:
sudo date -s "yyyy-mm-dd hh:mm:ss"

replace with  your current date and time

example: sudo date -s "2023-07-13 09:16:59"
Note:Time format is 24hour format so if it is 1:00PM, It tmeans 13:00

sudo date -s "2024-04-14 13:07:59"
6.Check if date and time is synchronized. Type timedatectl then press ENTER



7.If system clock synchronized is yes, proceed to step 8. For OPI PC/OPI One board proceed to step 8. Step 7 is not needed for OPI board.
If system clock synchronized is no, 

Open timesyncd.conf file then edit its content

To open, type this in the terminal:

sudo nano /etc/systemd/timesyncd.conf 


then press ENTER. Check the command's spelling, spacing and period.Always double check before you hit ENTER.
You should see this file content:

Please remove the comment (#) after [Time] then add this NTP server in the list.Copy and paste na lang para dina mag type:Yung hashtag # lang po.Wag yung buong line and edelete.

NTP=ph.pool.ntp.org
NTP=0.asia.pool.ntp.org
NTP=1.asia.pool.ntp.org
NTP=2.asia.pool.ntp.org
NTP=3.asia.pool.ntp.org

To edit, use arrow up and down, arrow left and right,backspace and ENTER key

The result should be look like this:
Ganito na dapat magiging itsura:



When you are done editing, save it. 
To save press CTRL+O then ENTER
To exit file press CTRL+X
To close putty type exit but do not close it, because you're not done yet.

Next 

  • Restart the systemd-timesyncd service:
    To restart type this command then press ENTER:

    sudo systemctl restart systemd-timesyncd.service
    Wait for a few minutes then check if system clock synchronized becomes "Yes"
    Once you've followed these steps, your Raspberry Pi's/OPI's clock should be synchronized with the network, ensuring accurate timekeeping.


8. Configure your DNS
Type this command on terminal sudo nano /etc/resolv.conf then press ENTER. Check the commands spelling, spacing and peiod.Always double check before ENTER.

You will see this result:



9. Edit it then add your DNS 1.1.1.1 and 8.8.8.8. Use arrow up and down, arrow left and right  to edit.

nameserver 1.1.1.1
nameserver 8.8.8.8

Add the router IP of your vendo machines Internet source:
If using VLAN, add your VLAN Routetr;s IP or IP ng VLAN device mo to access the admin dashboard of your VLAN router, kung naka enabled ang DHCP
If direct to ISP, add your ISP modem router's IP.Yung IP para mabuksan mo or ma remote ang ISP modem router.
Example 192.168.1.1, 192.168.254.254, 192.168.0.1, 192.168.88.1

nameserver 192.168.88.1

Add your vendo's interface IP

nameserver 10.0.0.1
nameserver 20.0.0.1

Take note: mas ok kung mauna ang DNS sa list

It should look like this after you edit:



What you will be adding in the list, depends on your Admin dashboard
10. After editing press CTRL+O then press ENTER to save.
    Press CTRL+X to exit file.
    Type exit to close putty
11. For OPI one/OPI Pc board only lock the resolv.conf file to prevent modification of changes during reboot.This is the terminal command:

sudo chattr +i /etc/resolv.conf

COMMON Question:

Bakit po blank or walang laman. Ano po ang gagawin?
A: Check spelling, spacing and period. Siguradong mali.

"Paano po ii edit boss saan magpipindot" sagot: To edit use arrow up and down, arrow left and right and backspace.
"Anong ilalagay":
Sagot: Depende sa kung anong makikita dashboard mo.Ito ang mga ilalagay Mga Ip ng interface ng VLAN at USB TO LAN. Sample sa picture above are 10.0.0.1, 8.0.0.1, and 20.0.0.1 IP ng main router mo kung saan kumukuha ng internet ang vendo machine/Ubuntu PC. In other words WAN gateway or yung IP para mabuksan mo and admin dashboard ng ISP modem router .Example 192.168.1.1, 192.168.254.254, 192.168.0.1 Last is IP of your DNS. This is the most important .Kaya wag pong kalimutan. Usually 8.8.8.8 at 1.1.1.1 Take note, depende sa makikita sa dashboard nyo po. Follow the format <nameserver space IP>
"Na edit ko na po, anong sunod?" Sagot: After editing press CTRL+O then press ENTER to save.
            Press CTRL+X to exit file.
