Description of SMART attributes

In this article I’ll look at the SMART information of the first SSD drive that comes under the arm and describe what the attributes mean.

Suppose we looked at the information on the disk /dev/sda:

sudo smartctl -a /dev/sda

I have the following information:

Addition of ONT Huawei EchoLife HG8110 on Huawei SmartAX MA5683T

On the test, I wrote the profiles and added ONT Huawei EchoLife HG8110 to Huawei SmartAX MA5683T.

The first step is to connect to the Huawei SmartAX MA5683T and go into configuration mode:

enable
config

Create ont-srvprofile:

ont-srvprofile gpon profile-id 14 profile-name "Huawei HG8110"
ont-port pots 1 eth 1
port vlan eth 1 translation 228 user-vlan 228
commit

Create ont-lineprofile:

ont-lineprofile gpon profile-id 14 profile-name "Huawei HG8110"
tcont 4 dba-profile-id 11
gem add 1 eth tcont 4
gem mapping 1 0 vlan 228
commit

We learn the serial number of ONT and the number of the card to which it is connected by typing the command to search for new ONTs:

display ont autofind all

Let’s go into the setup mode of the desired Gpon card (in the port of which the ONT is connected):

interface gpon 0/5

Now add ONT with the serial number:

ont add 3 17 sn-auth "414C434CF23D5EAF" omci ont-lineprofile-id 14 ont-srvprofile-id 14 desc OPISANIE
ont port native-vlan 3 17 eth 1 vlan 228 priority 0

Where number 3 indicates the Gpon port number to which the ONT is connected.

The number 17 means ID ONT and is listed next in order after added in the ONT configuration, the list of occupied IDs can be seen after exiting the Gpon card setup mode and typing the command displaying the entire configuration (for each gpon port, their IDs ONT):

display current-configuration
display current-configuration | include service-port

Let’s exit the Gpon interface configuration mode:

quit

Add a service port that will give the Internet to ONT (the number 425 denotes the port service number and is taken from the free in the configuration):

service-port 425 vlan 228 gpon 0/5/3 ont 17 gemport 1 multi-service user-vlan 228

Save the configuration:

save

The standard IP address of Huawei EchoLife HG8110 is 192.168.100.1, the login is telecomadmin, the password is admintelecom.
In ONT, you do not need to configure anything.

Solution of error CMOS Battery Low

Different BIOS can give an error in different ways, here are a few options:
CMOS Battery Low
CMOS battery failed
State Battery CMOS Low
CMOS Battery Has Failed
System battery is dead
CMOS Battery State Low

An error is displayed when the computer is turned on and indicates that the battery needed to store BIOS settings is empty.

The solution is to replace the battery. It is also possible to clean the contacts. To do this, you need to remove the battery from the motherboard, check if there are dust on the contacts, if there is a tester, then measure its voltage, it should usually be no lower than 3 volts.

Setting up and using Traffic Flow in Mikrotik

Enable Traffic Flow on the Mikrotik router:

ip traffic-flow set enabled=yes cache-entries=4k set active-flow-timeout=30m inactive-flow-timeout=15s interfaces=all

View settings:

ip traffic-flow print

Specify the IP address and port of the computer that will receive the Traffic-Flow packets:

ip traffic-flow target add address=192.168.88.240:1234 disabled=no version=9 v9-template-refresh=20 v9-template-timeout=30m

or

ip traffic-flow target add address=192.168.88.240:1234 disabled=no version=5

View settings:

ip traffic-flow target print

To configure through the GUI, the settings can be found in the menu IP -> Traffic Flow.

For monitoring under Windows, you can install the program ManageEngine NetFlow Analyzer, which will work as a server, receive packets from the specified port and generate graphs and statistics via a web server that can be opened by the browser.

For monitoring under Linux, you can install and configure for example flow-tools.

How to find out the password for Huawei EchoLife HG8245

Configured today GPON ONT Huawei EchoLife HG8245C to OLT and it was necessary to go to its web interface to change the password on Wi-Fi, and the standard root login and password admin did not fit. I had to perform several manipulations.
Of course, to begin with, connect to any of the LAN ports, wait until the DHCP ONT is turned on, it will give out IP, such as 192.168.1.2 or set it manually.
Connect via telnet to ONT IP 192.168.1.1, enter login root and password admin.
Then type the following commands one at a time:

shell
cd /mnt/jffs2/
grep admin  myconfig.xml

As a result, the last command gives information about what is happening in the web interface:

useradmin
vufum

and

telecomadmin
nE7jA%5m

Passwords can also be written on the device label. In the settings you can change the password, in this case the user will be useradmin and the specified password.
For HG8245, the standard administrative login and password telecomadmin \ admintelecom, for users – admin/admin. For Chinese HG8245C standard – telecomadmin \ nE7jA%5m.
There may be further passwords for telecomadmin:

NWTF5x%RaK8mVbD
NWTF5x%

The solution to the error 0x80073712. Component store has been corrupted

To fix the error “0x80073712. Component store has been corrupted” you need to open a CMD with administrator rights and run the following commands:

Checking the component store:

Dism /Online /Cleanup-Image /CheckHealth

Recovery:

Dism.exe /Online /Cleanup-Image /Restorehealth

For Powershell, the command looks like this:

Repair-WindowsImage -Online -RestoreHealth

You can also restore from the original installation disk by inserting a disk and executing commands in Powershell:

Repair-WindowsImage -Online -RestoreHealth -Source Е:\sources\install.wim:1

where E is the drive letter, and figure 1 is the edition number on the disk.

After the procedures, it is advisable to check the system files by typing the following at the command prompt:

sfc /SCANNOW

Solution of error with Detect operating system in Zabbix

The standard “Detect operating system” script does not work in Zabbix, when trying to execute it, the “sudo: no tty present and no askpass program specified” error appears, so for its operation it is necessary to take several actions.

The first is to install nmap:

apt-get install sudo nmap

The second is to allow the user of Zabbix to run nmap, for this open the file /etc/sudoers in any editor, for example nano:

sudo nano /etc/sudoers

and add the following line to it:

zabbix  ALL=(root) NOPASSWD: /usr/bin/nmap

or you can not open it in the editor, but execute the command:

sudo echo "zabbix  ALL=(root) NOPASSWD: /usr/bin/nmap" >> /etc/sudoers

After these manipulations, the script should work, determine the operating system, show the list of open ports, etc.
