From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Tailscale/synology/NFS remote access (lemm.ee)

UPDATE (13:40 ET / 2024-07-05): Got the connection working via SMB. Literally the only thing I changed was moving to a credentials file rather than specifying credentials inline, so ... I'll be trying to figure out what mystery affliction prevented the connection before. Leaving this up because there are a bunch of great suggestions for troubleshooting this issue in the comments. Thanks everyone.

ORIGINAL POST:

Currently pulling out my hair. I have a Synology NAS with the tailscale service (everything up to date). I have a NixOS client laptop, everything up to date.

I'm simply (?) trying to connect to a share via tailscale, and I have not managed to find anything that works. I've been using NFS, but I'm fine with SMB ... or carrier pigeons at this point.

Does anyone know of a step by step, detailed, current tutorial to accomplish accessing a Synology share via tailscale on a linux device? I would not have thought this would be challenging!

Did this ever work?

Does pinging by IP address work?

Go to your settings look at security, is the firewall enabled? Tried disabling it for now

In settings and security is autoblock enabled? Try disabling it for now

Did you follow the DSM-7 task setup? In DSM-7 tail scale cannot allow outbound connections unless you set up the appropriate tunnel permissions.

  1. I have tried with firewall enabled and disabled (and added the rule for the enabled firewall)
  2. I will check autoblock. That's one thing I haven't checked.
  3. I followed the DSM-7 task setup.

All fantastic suggestions, btw, but my hair-pulling is coming from none of them working (other than autoblock). :)

Does ping work? Have you validated tailscale?

Check the iptables on the device.

If that doesn't work it's time to do tcpdumps on the different internal interfaces of the Nas and see where it stops
