Date & Time

Summary

---

Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. This chapter is an overview of the NTP section for RUTX08 devices.

General

---

The Time Synchronization section lets you select time zone and synchronize the time.

The figure below is an example of the Time Synchronization section and the table below provides information about the fields contained in that section:

Field	Value	Description
Current system time	time; default: none	Current local time of the device.
Sync with browser	-(interactive button)	Click to synchronize device time and time zone to browsers, if your device time or time zone is not correct.
Time zone	time zone; default: UTC	The device will sync time in accordance with the selected time zone.

NTP

---

This section is used to configure NTP client, server and time servers.

Time Synchronization

---

This section is used to configure the device's time settings.

Field	Value	Description
Enable NTP Client	off | on; default: on	Turns NTP on or off.
Save time to flash	off | on; default: off	Saves last synchronized time to flash memory.
Force Servers	off | on; default: off	Forces unreliable NTP servers.
Update interval (in seconds)	integer; default: 86400	How often the device will update the time.
Offset frequency	integer; default: 0	Adjusts the minor drift of the clock so that it will run more accurately.
Count of time synchronizations	integer; default: none	The amount of times the device will perform time synchronizations. Leave empty in order to set to infinite.

Time Servers

---

This section is used to specify which time servers the device will use for time synchronization. To add more time servers to the list, click the 'Add' button.

Field	Value	Description
Hostname	ip | url; default: time[x].google.com	NTP servers that this device uses to sync time.

NTP Server

---

The device can also act as an NTP Server, providing clock synchronization to other devices in the network. From this section you can turn this feature on or off:

NTPD

---

The NTPD program is an operating system daemon that synchronizes the system clock to remote NTP time servers or local reference clocks. NTPD includes the ability to use this to keep your clock in sync and will run more accurately than a clock on a device not running NTPD. NTPD will also use several servers to improve accuracy. It is a complete implementation of NTP version 4 defined by RFC-5905, but also retains compatible with version 3 defined by RFC-1305 and versions 1 and 2, defined by RFC-1059 and RFC-1119, respectively.

Note: NTPD is additional software that can be installed from the System → Package Manager page.

Field	Value	Description
Enable NTPD	off | on; default: off	Turns NTPD on or off.
Enable NTP config from file	off | on; default: off	Run NTPD with uploaded configuration file.

Server	ip | url; default: 0.openwrt.pool.ntp.org	NTP servers that this device uses to sync time.
Enable Server	off | on; default: off	Enables NTPD server to make the router act as an NTP server so that it can provide time synchronization services for other network devices.

User Settings

Change Password

---

The User settings section is used to change the password of the current user.

System Users

---

Summary

---

The System Users page is used to add new user accounts that can access the device with different user credentials than the default ones. The newly added users can be assigned to one of two groups, either of which can be modified to limit WebUI read/write access rights for users belonging to each specific group.

This page is unrelated to SSH users. By default, there is one SSH user named "root" and it shares the same password as the default WebUI user named "admin".

This manual page provides an overview of the Users page in RUTX08 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Groups

---

The Groups section lists available user groups of which there are three:

---

• root - highest level of authority. Key elements that define this group:
  • has unlimited read/write access;
  • additional users cannot be added to this group;
  • access rights for this group cannot be modified.
  
  

---

• admin - second highest level of authority. Key elements that define this group:
  • limited read access; by default, users belonging to this group cannot view these pages:
    • System → Administration → Users Settings → System Users
    • System → Administration → Profiles
    • System → Maintenance → Backup
    • System → Firmware
    • System → Maintenance → CLI
    • System → Setup Wizard
    • System → Maintenance → Custom Scripts
  • limited write access; by default, users belonging to this group cannot view these pages:
    • System → Administration → Users Settings → System Users
    • System → Maintenance → Backup
    • System → Firmware
    • System → Maintenance → CLI
    • System → Setup Wizard
    • System → Maintenance → Custom Scripts
    • System → Administration → Access Control → General
    • System → Administration → Profiles
  • access rights can be modified.
  
  

---

• user - lowest level of authority. Key elements that define this group:
  • no write access;
  • limited read access; by default, users belonging to this group cannot view these pages:
    • System → Administration → Users Settings → System Users
    • System → Firmware
    • System → Maintenance → Backup
    • System → Administration → Access Control
    • System → Maintenance → CLI
    • System → Maintenance → Custom Scripts
    • System → Maintenance → Troubleshoot
    • System → Package Manager
    • Network
    • System → Setup Wizard
    • Services → Hotspot → General → Userscripts
  • access rights can be modified.
  
  

---

Additional note: you can view and/or edit settings for each group by clicking the 'Edit' button next to them. More on information on how to edit group access settings is located in the following section of this manual page.

Group Settings (edit group)

---

A group's parameters can be set in its Group Settings page. To access the Groups Settings page, click the 'Edit' button next to the group's name. Below is an example of the Group Settings section:

Field	Value	Description
Write action	Allow | Deny; default: Allow	Specifies whether to deny or allow write access for users belonging the group.
Write access	path(s) to page(s); default: System > Administration > User Settings > Change Password	Controls the ability of users to change and execute the contents (e.g. Network > Lan).
Read action	Allow | Deny; default: Deny	Specifies whether to deny or allow read access for users belonging the group.
Read access	path(s) to page(s); default: in the picture above	Path(s) to the page(s) to which the selected "Read action" will be applied. Click the plus symbol to add more entries.

Examples

---

The easiest way to master the syntax is to navigate to page that you want to generate a path for and the copy the path from the URL of that page.

For example, to specify the path to the Network → Mobile page, navigate to the page, copy the page's URL address starting from the symbol "#" and paste it into one of the access fields:

---

However, the VPN window contains links to many different types of VPN pages. If you want to specify only one of them, you can do it as well. For example, to to specify the path to the IPsec page, add "/ipsec" to the path string:

services/vpn/ipsec

---

An asterisk (*) in the path string means that the every page from that point on is included in that path. For example, to generate a path that includes pages in the Services menu tab:

services/*

Or to simply include everything in the entire WebUI (if this path is combined with Read action: Deny, users from that group will not be able to login to the WebUI):

*

Users

---

The Users section lists all created users and provides the possibility to change their passwords and the group they belong to (with the exception of the default user "admin" which always belongs to the root group).

By default, there is only one user called "admin":

User Settings (edit user)

---

Each user's password and group parameters can be set in their User Settings pages. To access the User Settings page, click the 'Edit' button next to the user's name.

However, you may want to add a new user at first. This can be done from the Add New User section below:

1. create a username;
2. create a password for the user (must contain at least 8 characters, including at least one upper case letter and one digit);
3. click the 'Add' button;

Recipients

The Recipients section is used to configure email users, which can later be used along with email related services, such as Events Reporting.

Certificates

The Certificates page is used for convenient TLS certificate and key generation and management. Generated files can be exported and used on other machines or locally on this device with functions that use TLS/SSL, such as MQTT, OpenVPN, IPsec and others.

Certificate Generation

---

The Certificate Generation tab provides the possibility to generate TLS certificates required for secure authentication and communication encryption used by some of the devices services.

There are six distinct generation methods (denoted by the selected 'File Type').

1. Simple - generates and signs a set of 2048 bit certificate and key files that include:
   • Certificate Authority (CA)
   • Server certificate & key
   • Client certificate & key
   • DH Parameters
   The CA file generated with this option automatically signs the certificates. In short, this option is used for convenience as it doesn't let the user set any additional parameters for the certificate files. Therefore, it should be used only when no other specific requirements are expected.
2. CA - generates a Certificate Authority (CA) file. A CA is a type of certificate file that certifies the ownership of a public key by the named subject of the certificate. In other words, it assures clients that they are connecting to a trusted server and vice versa.
3. Server - generates a server certificate and key. A server certificate validates a server's identity to connecting clients, while a key is responsible for encryption.
4. Client - generates a client certificate and key. A client certificate validates a client's identity to the server that it's connecting to, while a key is responsible for encryption.
5. DH Parameters - generates a Diffie-Hellman (DH) parameters file. DH parameters are used in symmetric encryption to protect and define how OpenSSL key exchange is performed.
6. Let's encrypt - generates SSL certificate.
7. SCEP - generates SCEP (Simple Certificate Enrollment Protocol) certificate.

Generation Parameters

---

Generating each type of file requires setting some parameters. This section provides an overview for parameters used in Simple and TLS certificate generation.

---

Simple file parameters

Field	Value	Description
Hosts	string; default: none	Appends hostnames to certificates.
IP addresses	IPv4 address; default: none	Appends IPv4 addresses to certificates.

---

TLS parameters or simply parameters that apply to each (CA, Server, Client, DH) file type are the size and common name of the generated file(s).

Field	Value	Description
Key Size	integer; default: 2048	Generated key size in bits. Larger keys provide more security but take longer to generate. A 2048 bit is the preferred option.
Name (CN)	string; default: cert	Common Name (CN), aka Fully Qualified Domain Name (FQDN) is a parameter that defines the name of the certificate. It should be chosen with care as it is not only used for easier management. For example, the Common Name should typically hostname of the server. It may also be used to differentiate clients in order to apply client-specific settings.

---

Subject information is not mandatory but can be used as user-friendly way to identify the ownership of certificate files by including such information as the owner's location and company name.

---

The Sign the certificate slider control whether the certificate will be signed automatically or manually after the generation is complete.

Field	Value	Description
Days Valid	integer; default: 3650	Length of the signature's validity.

---

The Certificate Manager page displays information on all certificate and key files stored on the device and provides the possibility export these files for use on another machine or import files generated elsewhere.

Certificate Import

---

The Certificate Import section provides the possibility to import certificates and files generated on another machine. To upload such a file simply click 'Browse' and locate the file on your computer, it should then start uploading automatically.

Certificates, Keys & Requests

---

The Certificates, Keys and Requests section display files generated on or imported to the device along with the most important information related to them.

By default, the lists are empty. A set certificates generated using 'Simple' file type would look something like this:

The 'Export' buttons are used to download the files from the device onto your local machine. The 'X' buttons located to the right of each entry are used to delete related files.

Root CA

---

The Root CA section is used to add a root CA certificate file to the device. There is a default file already preloaded on the device which will be overwritten by any uploaded file. The certificates must be in .pem format, maximum file size is 10 KB. These certificates are only needed if you want to use HTTPS for your services and the default file should be sufficient in most cases.

Profiles

Summary

Configuration profiles provide a way to create multiple distinct device configuration sets and apply them to the device based on current user requirements. This chapter is an overview of the Profiles page in RUTX08 devices.

Configuration Profiles

This section displays user defined configuration profiles:

---

To create a new profile, configure the device in accordance with your needs, go to this page, enter a custom name for the profile and click the 'Add' button. You can also choose to create a profile without any previous configurations. A new profile with the given name will appear in the "configuration profiles" list:

The 'Apply' button applies the adjacent configuration on the device.

Scheduler

The Profile Scheduler provides a possibility to set up a schedule of when the device should use one profile configuration or another.

Check Profile Scheduler Instance Example to get a better understanding at how Profile Scheduler Instances works.

General Configuration

---

The General Configuration section is used to enable the Scheduler itself. Created instances won't work unless this option is turned on.

Profile Scheduler Instances

---

The Profile Scheduler Instances section allows you to create profile Instances to be enabled during specific time intervals. To add a new Instance click Add button.

Note: new Instance can only be created if there is at least one custom profile created.

Profile Scheduler Instance Configuration

---

This page is used to configure profile, time and day of selected scheduler instance. Refer to the figure and table below for information on the Profile Scheduler Instance Configuration fields:

Field	Value	Description
Enable	off | on; default: off	Enable selected instance for scheduler.
Profile	profiles; default: none	Select profile which will be applied during specified time interval.
Interval Type	Weekdays | Month Days; default: Weekdays	Depending on your needs select whether you want to configure weekdays or specific month days.
Start Time	time; default: 12:00	Enter time of the start of interval in which scheduler will switch profiles.
End Time	time; default: 12:00	Enter time of the end of interval in which scheduler will switch profiles back.

End Day	Weekday [Monday..Sunday]; default: Sunday	Select a day of the end of interval in which scheduler will switch profiles back.
Interval Type: Month Days
Start Day	Day of month [1..31]; default: 1	Select a day of the start of interval in which scheduler will switch profiles.
End Day	Day of month [1..31]; default: 1	Select a day of the end of interval in which scheduler will switch profiles back.
Force last day	off | on; default: off	Force intervals to accept last day of month as valid option if selected day doesn't exist in ongoing month.

Profile Scheduler Instance Example

---

Scheduler will use profile instance if it is enabled and it's time interval matches device's date, otherwise default profile will be used.

Example - we have 3 profiles in total:

• default
• Profile A
• Profile B

We create profile instances for Profiles A and B:

• Profile A: 08:00 - 11:00
• Profile B: 13:00 - 20:00

During 11:00 - 13:00 and 20:00 - 08:00 default profile will be used.

Storage Memory Expansion

USB

---

The Storage Memory Expansion function provides the possibility to expand the device's flash memory with a USB mass storage device.

Memory Expansion

---

You can expand the flash memory of this device with a USB Mass Storage Device (MSD) and use the extra memory to install additional software packages. This section provides instruction on how to do just that. However, there are a few prerequisites and warnings to take note of before using memory expansion.

To be eligible for memory expansion, the USB MSD must meet the following restrictions.

• The MSD must be the last one (chronologically) inserted.
• If you are using a USB hub, the target MSD must be the last one attached to the hub.
• No important data on the MSD as it will be wiped during expansion setup!

When expansion is enabled, do not detach the USB device as this will delete the data stored on it. Changes made to the device configuration while expansion was enabled will disappear after it is disabled.

Enabling memory expansion

---

To successfully expand the flash memory of your device follow the steps described below.

1. Attach a USB Mass Storage Device (MSD) to the USB connector on the device and go to the Services → Storage Memory Expansion page.
2. Set the 'Enable storage expansion' slider to 'on' and click 'Save & Apply'.
   
3. You will see a pop-up asking for confirmation. Take note that if you continue from this point on:
   • your USB device's memory will be wiped and formatted to ext2 format;
   • your device's current configuration will be backed up and restored to this point if the USB drive is removed or memory expansion is disabled;
   • the entire procedure may take a very long time and includes a reboot at the end; exact time will vary depending on the size of the MSD (larger size will take longer; for example, using a 128 GB drive will take about 2 hours to fully set up, while a 16 GB will only take about 5 minutes).
   Click 'Continue' to proceed.
   
4. If all is in order you should see a 'Formatting MSD...' message on the screen. This indicates that the MSD is being formatted and integrated with the system. This procedure can take a long time and ends with a reboot of the device.
   
5. Your device's flash memory will be expanded once the reboot has finished. In order to check, log in to the WebUI and look to the 'System' widget in the 'Overview' page. Hover your mouse cursor over the 'FLASH' memory indicator; you should see an increase to the device's flash memory.
   

Disabling memory expansion

---

To successfully disable memory expansion follow the steps described below.

1. Go to the Services → Storage Memory Expansion page.
2. Set the 'Enable storage expansion' slider to 'off' and click 'Save & Apply'.
   
3. You will see a pop-up asking for confirmation. Take note that if you continue from this point on:
   • your USB device's memory will be wiped and formatted to NTFS format;
   • your device's configuration will be restored to the point it was before memory expansion;
   • the entire procedure will take up to 2 minutes including a reboot.
   Click 'Continue' to proceed.
   
4. If all is in order you should see a 'Formatting MSD...' message on the screen. This indicates that the MSD is being formatted and detached from the system. This procedure can take up to a couple of minutes and ends with a reboot of the device.
   
5. Your device's flash memory will be restored to normal once the reboot has finished. In order to check, log in to the WebUI and look to the 'System' widget in the 'Overview' page. Hover your mouse cursor over the 'FLASH' memory indicator; you should see your device's flash memory return to its regular size.
