Realtek r8125 2.5g NIC issue

In case this type of card can not reach full 2.5g speed on Microserver gen 10 plus, select from the System Utilities screen, then System Configuration > BIOS/Platform Configuration (RBSU) > PCIe Device Configuration > Advanced PCIe Configuration, select “PCI Generation 2.0” in Maximum PCI Express Speed. If it’s set to “PCI Generation 1.0”, the maximum speed can only reach 1.5gbps when you run iperf3 to measure the NIC bandwidth.

Nextcloud: Increase Upload Limits

For snap installation of Nextcloud, run the following commands:

snap set nextcloud"16G"
snap set nextcloud php.upload-max-filesize="16G"
snap set nextcloud php.max-input-time=3600
snap set nextcloud php.max-execution-time=3600

For non-snap installation of Nextcloud, set the following parameters inside the corresponding php.ini file:

php_value post_max_size="16G"
php_value upload_max_filesize="16G"
php_value max_input_time=3600
php_value max_execution_time=3600

Monitor Website Availability

It doesn’t make much sense to use DDNS on an IPv6 web site. Implementing a script to check the status and send email alert should be enough.

import smtplib
import requests

# replace with your own data
target_url = 'your_url_address'
smtp_server = 'your_smtp_server_address'
smtp_port = 'your_smtp_port_number' # for example: 587
smtp_id = 'your_smtp_login_id'
smtp_password = 'your_smtp_login_password'
email_from = 'sent_from_email_address'
email_to = 'sent_to_email_address'

# subject, header and body
subject = 'Subject: Alert for ' + target_url + '\n'
header = 'To:' + email_to + '\n' + 'From: ' + email_from + '\n' + subject
body = "Your webserver " + target_url + " is DOWN."
message = header + body

# define function to send email
def send_alert(msg):
    smtpObj = smtplib.SMTP(smtp_server, smtp_port)
    smtpObj.login(smtp_id, smtp_password)
    smtpObj.sendmail(email_from, email_to,msg)

# define function to check status of web server
def url_check(url):
        #Get Url
        # if the request succeeds
        if get.status_code == 200:
            print(url + ": is reachable")
            print(url + ": is NOT reachable, status_code:" + get.status_code)
    except requests.exceptions.RequestException as e:
        # print URL with Errs
        raise SystemExit(f"{url}: is Not reachable \nErr: {e}")

if __name__ == '__main__':

Create a cron job to run the script in every 5 minutes.
