ssh missfire on bpi-m5 noble

[gene1934]

I had to install (they were missing) sshfs, then fuse and finally ssh on a bpi-m5, using a 128Gb u-sd as boot media. iso was noble from a week ago's download, and updated at 2nd boot after establishing my /etc/hosts file based network.  I can ssh from it /to/ the main box w/o any problem. But any attempt to reverse into it /from/ another machine /to/ it is "connection reset by peer". I haven't touched /etc/ssh/*config's from default values. Is there something I need to set/reset in those files to restore incoming logins?  And no, I do not enable root logins. Also, systemd is still a puzzle to me if its involved.

 

Thanks for any advice.

I did look at it, but nothing yelled at me in a quick scan. Not sure what I s/b looking at.

 

Thank you Werner.

Network is down:

2: end0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000

 

All instances I could find.

 

I think your own networking methods conflict with what is common nowadays and also might be reason ssh server is not even running or depending on a pseudo random situation. Same as for other topic where you could not reach armbian repo server.

You might not have been looking at the newest dmesg, I had a hard time convincing NetworkManager to stop calling for dhcp and just use the static settings I gave it.  Everytime I looked it was re-enabled. Once I had convinced it to skip the dhcp BS, network is fine, apt works, ping -c1 yahoo.com works and FF can browse the whole planet.  Everything works except /incoming ssh/.

 

I can goto that printer and log into this machine, but I can't ssh into that machine.  I can't "ssh-copy-id gene@e5p" which aliases in the hosts file to 192.168.71.122, it's refusing the incoming connection that worked with 6 other machines.  Is there some other tool to trace this?  htop says it is ATM. 

 

Thank you.

To clarify that last line htop say's ssh_config is in the cmd listing. 

put a tail on /var/log/syslog since it has the newest "access time" of any file in e5p's /var/log

Further: "ssh gene@coyote" successfully logged into coyote, so assuming that ssh is running

set e5p's /etc/apparmor verbose on with nano.

from that login "ssh gene@e5p" gets "connection reset by peer", and NO update to syslog. The rejection is not even making it to ANY of the logs.  So what's next?  Switch back to a 64G u-sd? Is a 128G u-sd too big? I am out of ideas. And a $3000 3d printer is Dead In The Water, no way to restore its klipper /home/gene/printer_data directory after a forced upgrade from jammy to noble.

 

Thanks.
