To delete the Steam account, you need to write a message to the technical support, for this go to the official website
https://support.steampowered.com/kb_article.php?ref=1558-QYAX-1965&l=english

Сlick “I need help“, choose the category of the question “My account” and write a message that we want to delete the account.

A week later I received an answer in which I asked if I really want to delete my account.
To which I replied “Yes, I want to delete my account“, after that, about a week later, the second message came:

The Steam account was disabled at your request. All information posted by him in the Community has been deleted. You will no longer be able to sign in to this account or restore access to it.

SNMP OID and MIB for interfaces

Below I list the standard OID and MIB with a description for obtaining SNMP different statistics for the network interfaces of switches, routers, access points, network cards in servers, etc.

You can check OID and MIB from Linux for example with a command (where .1, this is an OID):

snmpwalk -v2c -c community 192.168.1.2 .1

You can see the description of network interfaces via OID (in parentheses MIB):

.1.3.6.1.2.1.2.2.1.2 (ifDescr)

List of port interface indexes:

.1.3.6.1.2.1.17.1.4.1.2 (ifIndex)

Status of the port, there is a link or not (1-up, 2-down, 3-testing, 4-unknown, 5-dormant, 6-notPresent, 7-lowerLayerDown):

1.3.6.1.2.1.2.2.1.8 (ifOperStatus)

Port status, enabled or disabled by software (1-up, 2-down, 3-testing):

ifAdminStatus

Time of last port change:

1.3.6.1.2.1.2.2.1.9 (ifLastChange)

Port traffic:

1.3.6.1.2.1.2.2.1.10 (ifInOctets)
1.3.6.1.2.1.2.2.1.16 (ifOutOctets)

For 64-bit traffic counters, MIB is used:

ifHCInOctets
ifHCOutOctets

Number of packets containing errors:

1.3.6.1.2.1.2.2.1.20 (ifOutErrors)
1.3.6.1.2.1.2.2.1.20 (ifInErrors)

The number of dropped packets that are essentially error-free, but were discarded for example to free up the buffer space:

ifInDiscards
ifOutDiscards

Physical adress:

ifPhysAddress

The size of the largest package that can be sent:

ifMtu

Interface Type:

ifType

Unicast packets:

ifIntUcastPkts
ifOutUcastPkts

Broadcast packet counter:

ifInBroadcastPkts
ifOutBroadcastPkts

Port speed:

1.3.6.1.2.1.2.2.1.5 (ifSpeed)

List of VLANs:

.1.3.6.1.2.1.17.7.1.4.3.1.1

Uptime of the device:

1.3.6.1.2.1.1.3 (sysUpTime)

Description of the device:

1.3.6.1.2.1.1.1.0

How to delete an invalid phone and email from Privat24

There were somehow many invalid phone numbers and email addresses in Privat24, I wanted to delete them, the tick “Actual” was naturally removed.

After communicating with technical support, I was informed that you can delete the email yourself by sending an SMS with the text OFF + mail@example.com to number 10060, where mail@example.com is the address of the current mail (when abroad, SMS should be sent to +380920003700).

And the operator of technical support made an application for removing phone numbers on their own and after a while they disappeared from the settings of the account.

Setting up a backup space for Hetzner.de

On the test went into https://robot.your-server.de/, has opened Main functions – Servers, selected the server and in the tab Backup activated free 100GB, since for servers costing 39 € or more this place was allocated for free.
Activated WebDAV to test, samba was already activated, it is also possible to connect via FTP, FTPS, SFTP and SCP using a user name and password, via SFTP/SCP, you can also connect using the key.
The speed of data transfer to the backup server depends on the number of connected users and their traffic.
When connecting, use a domain name, for example USER.your-backup.de, because the IP address can change.
Also, you can not create the /etc and /lib directories in place for backups.

For an example in Ubuntu Server, I will mount a backup location using SAMBA/CIFS.
Install the necessary utilities and create a directory in which we will mount:

sudo apt-get install cifs-utils
sudo mkdir /backup

Temporarily mount the place with the command:

sudo mount.cifs -o user=USER,pass=PASSWORD //USER.your-backup.de/backup /backup

To automatically mount after rebooting the system, add the following line to the / etc / fstab file:

//USER.your-backup.de/backup /backup   cifs  iocharset=utf8,rw,credentials=/etc/backup-credentials.txt,uid=SYSTEM_USER,gid=SYSTEM_GROUP,file_mode=0660,dir_mode=0770 0 0

To open a file it is possible for example with the text editor nano (CTRL+X for an output, y/n for saving or canceling changes):

sudo nano /etc/fstab

And add the following lines to the file /etc/backup-credentials.txt:

username=USER
password=PASSWORD

We will only set permissions for the file owner for security reasons:

sudo chmod 600 /etc/backup-credentials.txt

If you use the Windows operating system, you need to create a system user with the same login and password as the backup location.

Now I will connect to the test via WebDAV.
Install the necessary utilities and create a directory in which we will mount:

sudo apt-get install davfs2
sudo mkdir /backup

In CentOS:

yum install davfs2
mkdir /backup

Temporarily to mount through WebDAV a place it is possible a command:

sudo mount -t davfs https://USER.your-backup.de /backup

To automatically mount after rebooting the system, add the following line to the /etc/fstab file:

https://USER.your-backup.de /backup davfs rw,uid=SYSTEM_USER,gid=SYSTEM_GROUP,file_mode=0660,dir_mode=0770 0 0

And in the file /etc/davfs2/secrets the following line:

https://USER.your-backup.de USER PASSWORD

That’s all, in my case, you can save backups to the /backup directory.

Configuring printing in Firefox

To configure printing in Mozilla Firefox, open the settings menu on the right, select “Print “, in the preview window that appears, click the “ Options” button, in the next window that appears, put the tick “Compress to page width, and in the “Fields and headers and footers” tab, specify the required fields, in my case it was reduced to 1, because the checks were printed on a narrow tape of the thermal printer and standard Only a couple of characters fit in one line.

The second option is to type and open in the address bar:

about:config

Click “I take the risk!”
In the field “Search” type:

print_printer

Right-click on the desired printer and select “Reset.”

If this does not help, check the print settings in the printer properties, in the operating system control panel, and try printing in other browsers.
