DietPi

Hi, the SSH hostname (dietpi) stopped working suddenly. I don't know why, not received software updates. Then, I try to update it but not working anyway. I don't know why.
What can I try to solve it?

Thank you!

Sorry, also Samba via hostname stopped working

@crik91
What you mean by hostname? Can't you login anymore with the user "dietpi" or indeed can't you access your device from the local network with the hostname "dietpi", e.g. ping dietpi?

AFAIK the default hostname on DietPi is DietPi (respect capitalisation), but this is something I would change anyway, e.g. according to the external domain name.

If you mean login name, then try to login via root and investigate what has happened to the dietpi user.

Sorry, I mean that up 2/3 weeks ago I was able to connect via Samba to the raspberry using the name "samba", it was visible in "Network" in WinOS and the same in macOS, it was reachable via smb:\\dietpi but now it's not possible anymore. I don't know why.

Hmm, please run the following command on your DietPi to get the actual hostname:
hostname

Also check in your router settings if the device appears there with certain hostname or if you can assign one there.

I can connect via Samba only using the local IP address. Up to 2/3 weeks ago I was able to connect using "smb:\\dietpi" (yes, all lower letters) but now is not working also using "smb:\\DietPi" and the Samba server is not visible in my network as in the past. I don't know what it's changed.
Also in my router, the device was listed as "DietPi" and now something like PC-192-168-0-50 . I really don't know

Strange that it worked with lower case in the past, as the hostname is the shown capitalisation.
Ah just saw our Samba docs and indeed it seems to be possible lower case somehow: viewtopic.php?f=8&t=5&start=10#p56

Does the device connect to the network/router via DHCP? Does you router allow to manually add a hostname to the device, so change PC-192-168-0-50 manually to DietPi?

Also according to the docs it should be smb:\\dietpi\dietpi instead of just smb:\\dietpi, I guess since this must include the accepted Samba username.

In the WinOS PCs I was able to see "dietpi" listed (all lower letters) instead of "DietPi" as in the hostname. Now I can't see "DietPi", "dietpi" or anything else listed in Network.

Now I changed the name of the device in my router and it works again.

Yes, I always used "smb:\\dietpi" because I have 3 USB HDD in my smb.conf and typing just the server I was able to see a list of devices/folders to choose.

Not sure why suddenly the Pi does not show up by it's hostname anymore, but this is most likely related to the network/router and not the DietPi system itself.

Just to check whether the hosts file as well matches the hostname:
cat /etc/hosts

Perhaps reconnecting the Pi to the network would have also shown it again as its hostname in the network, or did you do reboots in between?
ifdown eth0
ifup eth0
However if it works now with the router assignment no need to further investigate for now.

Ah yeah of course. The second /dietpi in the Samba path just means to access the particular share named "dietpi".

Hi, this is my hosts file: No change after rebooting the eth connection
