The server has two active network adapters, both connected to the internet. One is used for outgoing internet traffic, the other for incoming. The incoming adapter lives on a public network segment (something like 88.236.133.104/29). I do have multiple servers within this segment. Typically, I update the server regularly, meaning: * ssh to the incoming adapter: ssh 88.236.133.108 * apt-get update * apt-get upgrade * apt-get dist-upgrade * apt-get clean * reboot It used to work ok. BUT: Today, "apt-get upgrade" seem to take really long when updating systemd. After a could of minutes, I realized that the ssh session became inactive. I couldn't type into it, I had to abort it via ~. . * ssh from the internet to the incoming adapter was not working anymore - ssh 88.236.133.108 * ssh via another server within the public network segment worked * ssh 88.236.133.106 -> ssh 88.236.133.108 * After running "netplan apply" everything was fine again Here my netplan configuration (I changed the ip addresses): network: version: 2 renderer: networkd ethernets: eno1: dhcp4: yes eno2: dhcp4: no addresses: [88.236.133.108/29] #gateway4: 88.236.133.105 routes: - to: 0.0.0.0/0 via: 88.236.133.105 table: 120 routing-policy: - from: 88.236.133.108/32 table: 120 - to: 88.236.133.108/32 table: 120 Unfortunately, I don't have the console output avalable anymore. Shall I provide additional info?
