Finns det någon loggfil (på Ubuntun eller Debian) jag kan kolla för

mattias idé låter inte helt dum men jag kompletterar med att du borde
kunna köra tcpdump (eller annat analysverktyg) på båda sidorna och se
om några paketsekvenser kommer fram alls.
Kanske nån kan hjälpa mig tyda vad det betyder. Debian-burken har IP
83.227.134.223, vilket jag inte kan hitta i loggen på Ubuntun.
Här är resultatet från Debian-sidan, dvs från den dator jag försöker
ansluta från (med ssh):
tcpdump host 79.102.88.186

Och så här ser det ut på Ubuntu-sidan, dvs på den dator jag försöker
ansluta till (med ssh):
