SSH - Never get to prompt ! Topic is solved

[SimonFili]

Hi There,

A second issue on my DietPi. First one is TimeSync, not resolved yet!

If I ssh, from putty on a Win10 PC on the same network. I never get a prompt.

The message gets displayed around 30seconds after I enter the password, then no prompt.

At one point, putty will timeout.

journalctl -ex shows that the password is accepted and the session opened.

But no prompt... now after 7 minutes!

htop is showing my session and low cpu

Any thoughts?

Did you tried with a different SD card? Do you use WiFi or Ethernet? Can you check for kernel messages dmesg -l err,crit,alert,emerg

[SimonFili]

Thanks for reply,

Right after the creation of the SD card (second time), SSH worked ok, but after around 1 day, stopped working

The Pi zero W is connected to Wifi

Here's the output of dmesg

I have not tried another SD card, only have one for now.

Running a check & repair disk with dietpi-drive_manager and reboot... did not see any messages, unsure if it ran?

Did ran a 100MiB benchmark... The SD writes at 4 MiB/s and reads at 21 MiB/s.

you could check status of SSH server systemctl status dropbear.service

As well, can you check if your network connection is stable?

[SimonFili]

I'm running OpenBSD SSH and the status is OK

The network is stable and fast, testing with ping to and from Pi

Thanks

[Joulinar]

as OpenBSD SSH isn't part of DietPi, you installed it yourself? correct? Did you stoppen and removed Dropbear before?

[SimonFili]

Here's the output of journalctl

I installed DietPi in a Hyper-V VM... no issue with SSH and Time sync. A bit faster on my i7-32gig than a Pi zero!

Fun debug here!

[Joulinar]

well this is the output for ssh for which you open the other topic
I will move it over

[Joulinar]

question: How does SSH behave if you stick to DietPi default Dropbear and did not change it towards OpenBSD SSH. If possible try with a fresh image.

[SimonFili]

I experienced the issue with a previous image + dropbear.

I will go back to dropbear on the new image and report
