Missing LAN IP with Linux Agent on Synology NAS

[janstalhut]

Server Info (please complete the following information):

• OS: Debian 12
• Browser: Firefox
• RMM Version (as shown in top left of web UI): 0.19.3

Installation Method:

• [X] Standard
• [ ] Standard with --insecure flag at install
• [ ] Docker

Agent Info (please complete the following information):

• Agent version (as shown in the 'Summary' tab of the agent from web UI): 2.8.0
• Agent OS: Linux: Synology DiskStation Manager (DSM)

Describe the bug The LAN IP is missing on Summary tab of the TRMM Dashboard

I have tried various Synology models from different generations: All of them seem to be affected by this problem:

• Devices with x86_64 and ARM processors
• Older and newer devices, large and small devices (e.g. DS216se, DS1817+)
• Various Linux kernels: 3.x, 4.x, 5.x
• Various (current) DSM versions: 7.1 and 7.2

To Reproduce Steps to reproduce the behavior:

1. Using the Linux Install Script to install the Agent on Synology via SSH
2. The field "LAN IP" on the summary tab is empty

Expected behavior Display of the correct LAN IPs (IPv4 and IPv6), like other Linux devices.

Additional context Unfortunately, I don't know how the agent determines the ip addresses. However, if I use the "ifconfig" or "ip address" command on one of the Synology systems, I get the details about interfaces and ip addresses.

If I can somehow help solve the problem with a debug log or something similar from the agent, please let me know.

It shows in your previous debug https://github.com/amidaware/tacticalrmm/issues/1970#issuecomment-2282688705
