Troubleshooting & Diagnostics
Troubleshooting and diagnostics required enabling of SSH access to your Synology NAS. It is also highly recommended to enable user home service.
Gathering a Monitoring Client Diagnostic Report
The Monitoring Client includes a built in tool to gather diagnostic data into a single zip archive to provide to Watchman Monitoring support.
This tool creates a zip archive containing the following paths (if they exist):
/etc/monitoringclient/tmp/monitoringclient/usr/bin/run-client/usr/share/monitoringclient/var/logs/monitoringclient
This zip is created as /tmp/monitoringclient-diagnosticdata.zip.
root access is not required.
Please SSH to your Synology NAS, and run the following command:
sudo /var/packages/monitoringclient/target/package/utilities/SupportToolOnce complete, you will be provided instructions to retrieve the zip archive from your Synology NAS.
Archive created successfully.
The following command can retrieve the diagnostic file:
scp -P 22 watchmanmonitoring@172.16.46.245:/tmp/monitoringclient-diagnosticdata.zip ~/Desktop
Adjust port "22" to match the setting in the Synology's SSH Service, in its Control panel, under Terminal & SNMPEnabling SSH
SSH in the DSM is disabled by default. It can be enabled in a few easy steps.
SSH access is only available to members of the administrators group.
Log into your DSM web interface, and open Control Panel.
Navigate to Applications > Terminal & SNMP.
Check Enable SSH service and set your preferred port number (22 is the default).
Click Apply.
User home folders is disabled by default. Logging in using SSH will present an error message.
Could not chdir to home directory /var/services/homes/admin: No such file or directory
Enable Public Key Authentication
By default, Synology does not support SSH Key authentication. Using keys is a more secure method of authenticating to your Synology NAS. The following steps allow you to enable PKA on your Synology NAS.
User Home Service is required to store the PKA.
After enabling SSH with the step above, ssh into your Synology NAS:
ssh -p <port> user@syno-hostname-or-IP-address
We will open the SSH server configuration file for editing:
sudo vim /etc/ssh/sshd_config
Find the following lines and uncomment them (by removing the #):
#RSAAuthentication yes
#PubkeyAuthentication yes
In vim, type i to get into insertion (edit) mode.
Press the escape key to exit the insertion mode.
Type :wq (colon-w-q) to write out the file and quit vim.
Adjust some permissions to ensure the SSH service has the correct permissions for the authorized keys file:
mkdir ~/.ssh
chmod 755 ~
chmod 700 ~/.ssh
touch ~/.ssh/authorized_keys
chmod 644 ~/.ssh/authorized_keys
Restart sshd using the following command:
sudo synoservicectl --reload sshd
You will be logged out of the SSH session.
On your computer, create your SSH key:
ssh-keygen -t rsa
Copy the key to your Synology NAS:
cat ~/.ssh/id_rsa.pub | ssh user@syno-hostname-or-IP-address "cat >> ~/.ssh/authorized_keys"
You should be able to SSH into your Synology NAS using PKA.
Enabling User Home Service
Enabling the User Home Service is not required, but can make for easier access to transfer files on and off your Synology NAS.
Log into your DSM web interface, and open Control Panel.
Navigate to File Sharing > User.
Check Enable user home service and select a location to house the home directory.
Click Apply.
