![]() I wish they had updated the man pages or changed the behavior to error out if you specify an IP address with local=, since this change breaks previously working-albeit ambiguous-configurations. So youre very likely safe - as far as sudo is concerned, at least. Before it was an alias for server even in the case where you did specify an IP address. Note that, like most security conscious software, sudo fails safe- if it cant look up the host, any entry that specify a host value is considered invalid. local is a synonym for -server to make configuration files clearer in thisīut it seems now that local is only a synonym for server in the case where you don't list an IP address. Local and it may answer queries from /etc/hosts or DHCP but should never forward queries on that domain Quoting the man page: Also permitted is a -S flag which gives a domain but no IP address this tells dnsmasq that a domain is The man page for dnsmasq did not change, but the behavior seems to have changed. I changed the line to: server=//1.1.1.1Īnd it went back to resolving correctly using the DNS server. The setup used to work fine, but I had a line like this: local=//1.1.1.1Īnd after the upgrade it would return 1.1.1.1 as the IP when I tried to ping īefore the upgrade it would use 1.1.1.1 as the DNS server and return the resolved IP address. Wow, I just found a very different explanation for dns breaking on an upgrade to 22.04. Run netplan apply afterwards to ensure you still have connectivity (careful with running this on servers you have no other access to!) or reboot. LXD container config with hardcoded IPv4, gateway and DNS resolvers etc/netplan/00-installer-config.yaml network: Possible files that may(should) be present on your system - run ip a and ip r and replace values and device names as required:ĭefault generic config created by subiquity which will probably suffice unless you have specific needs If there is no configuration file (check ls /etc/netplan/*.yaml) on your system, you will not get a DNS resolver configured by default.Īll of the hack recommendations to override systemd-resolved service unit or the /etc/nf directly are just covering up the symptom. Netplan configuration is created on a fresh install, but if you've an upgraded system, the necessary configurations are not present. Noticed that expected /etc/systemd/system//10-machine.This seems to be caused by Ubuntu 22.04 expecting to be configured via netplan. generic-ssh-user has password-less sudo privileges. Run the sudo ufw status verbose command to see the rules that are set. Respond to the prompt with y and hit ENTER. You already set up a firewall rule that allows SSH connections, so it should be fine to continue. Is there a reason why this particular ssh command would fail while the others do not? Is there a way to get around this, or better yet fix it?Įrror getting SSH command to check if the daemon is up: ssh command error: sudo ufw enable You will receive a warning that says the command may disrupt existing SSH connections. # See sudoers(5) for more information on "#include" directives:Īnd I am able to ssh into the server with no password from the machine where I am running the docker-machine command. # Allow members of group sudo to execute any command # Members of the admin group may gain root privileges # See the man page for details on how to write a sudoers file.ĭefaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:$ # Please consider adding local content in /etc/sudoers.d/ instead of # This file MUST be edited with the 'visudo' command as root. Another option is to use the ssh-keygen command: ssh-keygen -R 203.0.113.0. ![]() On an OpenSSH client, you can find the host entry in the /.ssh/knownhosts file and manually remove it. On the server, the /etc/sudoers file looks as such: Alternatively, you can manually remove the entry.
