SOLVED hostname nor servname provided, or not known

[sdgenxr]

OK, I'm about over with FreeNAS. When it works, it works fantastically! When it doesn't, I'm pulling my hair out for days/weeks and giving up on it completely. After the update that killed SMB v1, I lost access to my shares via browsing by hostname (\\server), and could not connect via IPMI (separate issue). Over the past few weeks, I've needed files of the server and was finally able to connect via IPMI and browse files via IP address (\\192.168.1.100). After a few updates, reading many threads about hostname issues, I was able to view my shares via hostname (\\server) briefly. Now I cannot browse via hostname again and get the below error when trying to browse available plugins.

Combined with this challenge and the difficulty in setting up users inside of jails to read/write files to the shared folders, I'm really at my wits end with FreeNAS and don't want to be. Any advice, guidance to ease me back from the edge would be greatly appreciated.

fter the update that killed SMB v1, I lost access to my shares via browsing by hostname (\\server)

Have a read: https://www.ixsystems.com/community...s-network-neighbourhood-better-than-ever.106/
Not that it would prevent you from accessing the server via the hostname, that's always worked fine. \\server in Windows Explorer and off you go.

As for your traceback, sounds like DNS is failing, typically because it's not been configured or acquired from DHCP.

Huge thanks for that first link! It does a great job of explaining what is going on after the depreciation of SMB1 and is something that I've been looking for a long time. My only question is how to do I go about actually downloading and running wsdd? Forgive my lack of experience with basic shell commands.

Regarding the traceback, how do I go about resolving that issue? I have a nameserver (1&2) defined in the network global config, along with the same nameservers on my router that serves as a DHCP. Just as an FYI, I do have the FreeNAS box set to matching static IP's on the router and FreeNAS machine.

Thanks!

If it's configured, try again. It might have been a simple network hiccup.

Fixed the error. Turned out I forgot to update the gateway after updating the nameserver.

Thanks! I'll keep digging on the wsdd install and start another thread if needed.
