I've had my Raspberry pi 4 setups for a while. Using it as a VPN, Plex, and basic WordPress host. I've been using SSH for a while and it worked fine.

I've recently caused an issue where immediately after connecting over SSH, my Raspi closes the connection. It is making it past the sshrc files (Post-login banner and Pushover notification script), but before I can even try to type anything, the connection closes with the output Connection reset by 10.0.1.175 port 22.

My terminal looks like this:

This last line is all I can see that indicated whats happening.

Here is the Auth log:

But none seem to have any useful information to me...

I have looked through the other posts and tried their suggestions to no avail:

  • Clearing Fail2Ban jail
  • Checking for SSH allow and block definitions (neither exist)
  • etc.

I use keypasswith KeyAgent for hosting my SSH keys (mimics Pageant). This has worked fine in the past, but has suddenly stopped working.

I did make some changes to my server, but they were related to plex and shouldnt make a difference to the SSH setup.

It seems like it is running ssh [ip] [command] of some sort, because that is what the return seems like.

Also, here is the output from ssh -vvv:

  • How did you install ssh on the PC? It should be done as an admin user...

  • SSH on my Windows 10 PC (client) was installed normally. It has worked in the past regardless, so it shouldnt be the install.

  • I only see debug logs from the client side. Set LogLevel DEBUG[1,2,3] in /etc/sshd_config on rasnas, do sudo systemctl restart ssh and look at its logs. What do you find?

EDIT: This only seemed to fix the problem temporarily!

FOUND THE SOLUTION!

It seems it was an issue with the router.
My DHCP IP range was set to be 10.0.1.100-10.0.1.200.
This seemed to cause an issue with how the router handled the traffic between devices and would drop connections.

I set the DHCP range to 10.0.1.2-10.0.1.202 and it seems to work fine now.

Thanks for the help!

Have you ruled out IP address conflict - some other computer on your network using the same IP address as the Pi? "Connection reset" is often a symptom of IP address conflict. For example, you could run Wireshark on your Windows host and watch the MAC addresses of the packets using the 10.0.1.175 address.

  • It doesnt seem to be an issue. I pulled the RaspberryPi offline (ssh [host] ("sudo shutdown") and im not getting anything for pinging the IP address... It seems to be the only device. I also setup a static IP for the RaspberryPi, but I havent allocated a DHCP reservation for its MAC address. I dont think I should need it if the Pi is asking for a static IP.

I never did find an answer to this problem.

I eventually fresh-installed the server and reconfigured it (Switching to containerized hosts)

This solved the issue... But not sure what the issue was 😕

For me, I tailed the auth.log, tried to ssh in, and found that sshd was unhappy because there were no /etc/ssh/ssh_host_* files. Fixed as follows:

ssh pi@localhost   #this fails
tail /var/log/auth.log      #this tells me the problem
ls -l /etc/ssh/ssh_host_*    #this confirms that these files are all empty
sudo rm /etc/ssh/ssh_host_*  #this removes the empty files
sudo ssh-keygen -A           #this generates new ssh_host_* files
ssh pi@localhost   #this works now
