[Bug 1776576] Re: Ubuntu 18.04 uograde: samba fails to run
Thanks for getting back to us. I suspect at some point you thought that the right service to start was samba-ad-dc, and you configured it like that, and forgot it. I also find this confusing and hope someday we can have the "switch" between services be automatic, depending on whether you want an AD server or not. Regarding your smb1 issues, it's not that samba won't negotiate using smb2 or 3. It will. The problem is the network browsing, which relies on smb1. Without smb1, you won't see the other windows/smb machines in the network. But if you try to access them directly via their ips or hostnames, the connection will work and smb2 or smb3 will be spoken just fine. See https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1767454 for some details. I'll leave this bug open as "incomplete". If it happens again, or if you gather more details, then feel free to post them here. Otherwise, the bug will auto-close in about 60 days.

[Bug 1776576] Re: Ubuntu 18.04 uograde: samba fails to run
Sorry for the delay in responding. Everything is finally resolved. Here is what I found. The Ubuntu OS was upgraded for a week and the system was rebooted multiple times before I noticed the samba problem. At that point, in addition to trying to start the samba-ad-dc service, I also had tried manually to start smbd and nmbd multiple times and received similar error messages with a failure of either starting. Since the services were not running there was no output in the /var/log/samba log files. Running testparm was showing no problems other than the unimportant warnings: rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) WARNING: The "syslog" option is deprecated neither of which should cause any problem. I do not believe that I changed anything significant, yet upon another system reboot both smbd and nmbd services started automatically and they continue to run properly upon subsequent reboots. I'm afraid I cannot explain why this is the case. Things like this are usually user error, but I cannot identify what may have been the problem. Now, the Ubuntu system could see the samba and external Windows shares. However, the Windows 10 machines could not see the samba server! This turned out to be due to a recent push of Windows 10 version 1803 which changed smb behavior by disabling the SMBv1 protocol, supporting only v2 and v3 by default. Now, why samba could not negotiate using these protocols is unclear, but the workaround was to re-enable SMBv1 on the Windows 10 machines, at which point they could negotiate with samba once again. A second difficulty was that it was impossible to connect to the samba server using the normal username and password that had worked in the past. The only solution I was able to discover was that the connection had to be established with hostname\username rather than username alone. Then everything was back to normal. Someone may want to take a look at Windows 10 v1803 to see how it is interacting with the standard samba configuration. In the future Microsoft may eliminate support for SMBv1 altogether. Sorry I don't have anything more definitive as to why smbd/nmbd were not running, but I really appreciate the feedback and support. Let me know if I can provide any additional useful information. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776576 Title: Ubuntu 18.04 uograde: samba fails to run To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1776576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The samba-ad-dc service is meant for samba when it is configured as an Active Directory Controller. Since your role is "standalone server", the services you should try to start/stop/restart/etc are called smbd and nmbd, as they were before. You should check why, if still happening, these are failing: sudo systemctl restart smbd nmbd If they are still failing, please attach their output and the logs from /var/log/samba/log* Also please run the testparm utility to verify your smb.conf for syntax. I can't do it with the file you provided because of the bits you sanitized. ** Changed in: samba (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1776576 Title: Ubuntu 18.04 uograde: samba fails to run To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1776576/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
