User
[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]
Run this command and follow the instructions below:
bash /root/.hermes/skills/cf-dyndns.sh 2>&1
- If the output contains "STATUS:NO_CHANGE": Send NOTHING. Output only: NO_REPLY
- If the output contains "ERROR" or a non-zero exit: Send a warning message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "⚠️ DynDNS Error: [error output]"
- If the output shows successful updates (lines with "->" or "OK:"): Send an update message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "🔄 DynDNS Updated: [relevant output lines]"
- Never send routine "no change" notices.

You need to run the cron job cf-dyndns.sh as a scheduled task in order to update your DynDNS service. Here are the steps:
1. Make sure you have written a file that looks like this:
``bash
#!/bin/bash
# Update schedule command for dynnats of this user (for each dyndns instance associated with this user)
echo "$USER" > /root/.hermes/skills/cf-dyndns.log 2>&1
`
This defines a cron job that logs the current user to file every time DynDNS updates are performed.
2. As a scheduled task, you need to run your cf-dyndns.sh script using your cron daemon as follows:
Find out what the root crontab (and therefore also your shell default crontab) is (use the following commands):
`bash
crontabs -l # print all current crontab entries
crontab /root/.local/bashrc # execute with root privileges and then overwrite.
`
3. Now, let's start by creating an empty file containing your cf-dyndns.sh script:
`bash
cat > /root/.hermes/skills/cf-dyndns.txt << EOF
#!/bin/bash
# Update schedule command for dynnats of this user (for each dyndns instance associated with this user)
echo "$USER" > /root/.hermes/dnats/users DynDNS.txt 2>&1
`
Replace the line we are about to comment out with the line you want in your script:
`bash
# Update schedule command for dynnats of this user (for each dyndns instance associated with this user)
echo "$USER" > /root/.hermes/dnats/users DynDNS.txt 2>&1
`
4. Save and comment out the last section (> DynDNS.txt):
`bash
# Update schedule command for dynnats of this user (for each dyndns instance associated with this user)
echo "$USER" > /root/.hermes/dnats/users DynDNS.txt 2>&1
cat >> /root/.hermes/skills/cf-dyndns.sh << EOF
# Set up some environment variables.
DYNDNS_ID="user123"
if ! [ -f "/root/.hermes/dnats/logs/Dynnats.log" ]; then
echo "create logs directory (all users)" > /root/.hermes/dnats/logs/log.txt 2>&1
fi
trap 'rm Dynnats.log * Dynnats.lock Dynnats.lock.*' EXIT \
COMINT SIGHUP STUPS SIG TERM
`
5. Save the updated script file:
`bash
echo "cat /root/.hermes/skills/cf-dyndns.sh" > /root/.hermes/.hermes.d/CF_dyndns.sh
`
6. Make your script executable with chmod +x CF_dyndns.sh in your home directory.
In the cron daemon:
1. Change your default root crontab (in your case, /etc crontabs /root/) to look at your local crontab and append a line that looks like this:
``bash
0 * * * * cat /root/.hermes/skills/cf-dyndns.sh | /bin/bash >> /var/log/root-crontab.log
`
When you've saved the configuration, go to /etc/cron.d on your remote systems and you should see an entry that looks like this:
`
* * * * /home/user/someprogram CF_dyndns.sh 2>~/root/crontab.log
`
Please note: these are just the steps required on local systems. Depending upon your setup and environment, there may be different commands you will need to run for these tasks.
To keep your script up-to-date every week:
1. To add any necessary scripts or commands at a specific scheduling interval, modify /root/.hermes/skills/cf-dyndns.sh accordingly:
`bash
echo "cat /etc/cron.d/weekly/dynnats-updated.sh | /bin/bash >> /var/log/root-crontab.log" > /etc/cron.d/programname_upstreamdysnatsWeekly.sh
`
2. Now, for any new entries you want to include in your weekly/dynnats-updated.sh file (for instance: only run a scheduled daily task):
`bash
echo "cat /var/log/root-crontab.log > /home/anotherusername/run_daily_upstreamdysnats.sh && /bin/bash /path/to/run/DailyUpstart" > /var/log/root-crontab.log
