Email 2 to SMS only works as root from cli in TRB245

Hello,

i have installed email_to_sms on a TRB245.

Set up all data by webinterface as “admin” and the job doesn´t run. SMS forwarding to email works.

By CLI login as admin the command “email_to_sms read” doesn´t work. By CLI login as root it works.

I don´t find the part of configuration on the webinterface or i think the add-on is wrong installed on the interface… ???

Thanks for tips

Greetings, @AquaChris ,

Welcome to Teltonika Community,

Thank you for reaching out regarding the Email-to-SMS functionality on your TRB245 device.

The reason the email_to_sms command only works when logged in as the root user is due to system-level permissions on the device. The command requires access to system resources, such as the SMS modem and background services, which are restricted to root for security reasons. The WebUI admin account is intentionally limited to configuration and monitoring tasks and does not have permission to execute system-level commands directly.

Please be assured that once configured via the WebUI, the Email-to-SMS service runs automatically in the background with the required permissions, so daily operation and monitoring can be performed safely through the WebUI without needing root access.

Let me know if you have any additional questions,

Best regards,
V.

Hello Villus,

thanks, but it don’t works. There is no logging for traffic on TRB and also no incoming traffic on the mailserver. If i set a cronjob as root ( only whanted for temp) to em… read everything works and also the settings i done in webUI are used.

Greetings,

I hope this message find you well,

To better understand the issue, could you please clarify the following:

  • Exact use case scenario.
  • How do you want to monitor the email traffic?
  • Is monitoring should be done by admin?

Waiting for your reply.

Warm regards,
V.

Hello,

  • first I install email2sms service from paketmanager
  • config this and wait
  • Nothing happened
  • I tried second different mailserver and multiple settings
  • Nothing happened
  • I monitor nettraffic in my private network, nothing seen
  • I monitor incoming connections on my own mailserver, no try to connect from the device to the mailserver. No handyshake nothing
  • I login cli by admin, run email_to_sms read, nothing happens
  • I changed to root, try again and email_to_sms read connects, read undone mails and send via modem to mobiledevice
  • I set temporary a crownjob as root for email_to_send read every 5 minutes and service works

By the way. Yesterday I installed ddns service and this service also don’t run at times for update in the settings there. It seems that no cron is running by webui installed instances

Greetings,

Thank you for your follow-up.

Email to SMS Forwarding is a feature that connects to an email account and periodically checks the inbox at a defined interval. When a new email with a specific subject is detected (the phone number provided in the email subject), the router sends the email body as one or more SMS messages to the recipient specified in the subject field.

Recommendations:

  • The Email to SMS application may not perform optimally if the email inbox is heavily populated. It is recommended to keep fewer than 100 emails in the inbox.
  • Fewer emails generally result in better performance.
  • In most cases, using a dedicated email inbox for this function is the best practice.

For more information about this functionality, please refer to the following article:

Additionally, please note that admin and root users have different system-level permissions. As a result, certain features may not function correctly when using the admin user instead of the root user.

Regarding the DDNS service, I kindly ask that you create a separate topic to avoid confusion and to ensure proper tracking of each issue.

Best regards,
V.

Thanks for answering,

I have a separate account and inbox for the service.

I see that default user “admin” is in group “root”. I install all feature as admin.

Could be this the problem? Is it possible that all packets must be installed as a user in group “admin”?

Hello,

The behavior you are observing—where the service works only when logged in as root via CLI but not as admin—is due to differences in system-level permissions between the two users. Some features require root-level access to function correctly.

The packages are installed directly on the device and are not user-specific. However, permissions to execute CLI commands are assigned based on the user account.

I hope this clarifies your question.

Warm regards,
V.

Okay, but your answer don’t finish the problem. No jobs from installed pakets run by there schedule settings.

Greetings,

Thank you for your message,

Could you please be more specific on what do you have in mind here?

Are you scheduling it as cronjob? Which role are you using? Please provide me with a step by step instructions so I could replicate the issue and investigate further.

Because you mentioned in the previous replies that:

Additionally, you can share a use case for your scenario, this will help me better understand the issue and assist you further.

Looking forward to your reply,

Warm regards,
V.

Here are the steps in post “5”

Schedules are in the default pakets set, for example every 2 Minutes via WebUI by email2sms. But it don’t work.

Same with other pakets for example ddns with update every 10 hours

Greetings,

Thank you for your message,

Can you confirm if the feature works while you’re trying to execute it as a root user?

Kind regards,

Hello,

not over WebUi, but it works by terminal as root on command line via “email_to_sms read”.

Greetings,

Thank you for your message,

WebUI in the WebUI you can configure the Email-to-SMS service, but it does not provide a direct manual “run now” command or interface button to execute the read action from the browser.

The WebUI is intentionally limited to configuration and status, not arbitrary system command execution.

Additionally, running system utilities (like email_to_sms read) involves permissions and access to the modem that are restricted to root for security reasons.

I hope this answers your question.

Warm regards,
V.

Thank and okay this seems to be the way to fix the problem.

Is there a part in WebUi to make the configuration for the system cronjobs or must the be set via CLI(terminal) as root by crintab -e?

Greetings, @AquaChris,

Thank you for your message, and apologies for the delayed response.

The only way to edit cron jobs on the device is via CLI; there is no built-in option in the WebUI to modify them.

For more detailed information on crontabs and how to work with them, you can refer to this wiki article:
