Does not match the name and ip address in the ubuntu 16.04 server. All that did was pick the samba config and add users to the system. What could be the problem and how to solve it?

sudo /etc/init.d/samba restart sudo: unable to resolve host servername sudo nano /etc/hosts 127.0.1.2 servername ping -c1 servername ping: unknown host servername

UPD 1:

 cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 r2d2 127.0.1.2 servername cat /etc/hostname r2d2 ip a sh scope host 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever cat /etc/nsswitch.conf # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat gshadow: files hosts: iles mdns4_minimal [NOTFOUND=return] dns mdns4 wins networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis

Still a mistake:

 sudo: unable to resolve host r2d2
  • attach to the question the entire contents of /etc/hosts , /etc/hostname , /etc/nsswitch.conf , and the output of the command $ ip a sh scope host - aleksandr barakin

 $ cat /etc/nsswitch.conf ... hosts: iles mdns4_minimal [NOTFOUND=return] dns mdns4 wins ...

correct the typo: instead of iles there should obviously be files
