Public bug reported: Description: Ubuntu 18.04.1 LTS Release: 18.04
winbind: Installed: 2:4.7.6+dfsg~ubuntu-0ubuntu2.2 Candidate: 2:4.7.6+dfsg~ubuntu-0ubuntu2.2 Version table: *** 2:4.7.6+dfsg~ubuntu-0ubuntu2.2 500 500 http://gb.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 100 /var/lib/dpkg/status 2:4.7.6+dfsg~ubuntu-0ubuntu2 500 500 http://gb.archive.ubuntu.com/ubuntu bionic/main amd64 Packages This is essentially a confirmation of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=825380 I had the combination of smb and autofs working in Ubuntu 16.04 and then recently upgraded to 18.04. I hadn't checked my back-up logs that used autofs+smb for a while but today noticed that autofs claimed that it could not resolve my Win10 hostname (the remote backup endpoint). I found the above Debian bug report and can confirm that the issue is present in 18.04. Steps to reproduce: # ping abcomputer ping: abcomputer : System error # nmblookup abcomputer 192.168.1.8 abcomputer<00> 192.168.5.1 abcomputer<00> Note the 192.168.5.1 IP is a Virtualbox host-only interface on the Win10 machine. I then remove the host-only interface from the Win10 computer # nmblookup abcomputer 192.168.1.8 abcomputer<00> # ping hyperion PING abcomputer (192.168.1.8) 56(84) bytes of data. 64 bytes from 192.168.1.8 (192.168.1.8): icmp_seq=1 ttl=128 time=0.533 ms ** Affects: samba (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1802628 Title: winbind name resolution fails when remote host has multiple IPs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1802628/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
