[Bug 1789097] Re: winbind does not work after reboot on Mint 19 / Ubuntu 18.04
Actually, no, that doesn't work for me. Was expecting it would given the comments on the samba bug, but, well, no. It *does* work to send HUP once booted: rene@t5500:~$ ping WD-NETCENTER ping: WD-NETCENTER: Name or service not known rene@t5500:~$ sudo kill -HUP $(systemctl show winbind -p MainPID --value) rene@t5500:~$ ping WD-NETCENTER PING WD-NETCENTER (192.168.1.33) 56(84) bytes of data. 64 bytes from fs7-netcenter (192.168.1.33): icmp_seq=1 ttl=64 time=1.86 ms It seems the networkd-dispatcher script is still too early. Must by the way also admit I'd maybe not consider it a better workaround even it if did work than just waiting for network-online.target; nmbd as mentioned already does as well, so only people with minimal Windows- networking needs or wants would get any potential benefit from NOT simply waiting for network-online.target. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789097 Title: winbind does not work after reboot on Mint 19 / Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/1789097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1789097] Re: winbind does not work after reboot on Mint 19 / Ubuntu 18.04
Thanks much for checking. I see; I was expecting this to be an
"immediately obvious" sort of thing to someone with unlike me an actual
clue about samba/winbind, but I have with the above guidance nos
supplied more information.
Specifically, it would appear that your explicitly mentioned "wins
server" configuration will be the difference. I never expected my
/etc/samba/smb.conf to be relevant since mine is fully vanilla, as
provided by the "samba-common" package. It is also attached, but:
rene@t5500:~$ debsums samba-common | grep /usr/share/samba/smb.conf
/usr/share/samba/smb.conf OK
rene@t5500:~$ cmp /usr/share/samba/smb.conf /etc/samba/smb.conf
rene@t5500:~$
This is to say that I do not in fact have a WINS server specified; that
judging by the logs my winbind is relying on broadcasts, and bombing out
in that case if started before network-online.target.
There's two logs attached with "debug level = 5", one log.winbindd-
nonworking and one log.winbindd-working, in which "nonworking" is
without /etc/systemd/system/winbind.service (i.e., default) and working
with.
In the nonworking situation the log shows:

So, I guess it's broadcasts that need network-online.target. Seeing as
how relying on those is the vanilla situation I take it this still means
the "winbind" package wants the service file adjustment?

[Bug 1789097] Re: winbind does not work after reboot on Mint 19 / Ubuntu 18.04
I'm trying to check why winbind won't recover from the network being down, so I setup a lxd container where I installed just winbind and the nss module. My /etc/nsswitch.conf reads: hosts: files wins dns (I would have ordinarily put dns before wins, but ok, let's try to reproduce this) smb.conf has: [global] ... wins server = 10.10.222.254 That IP is another samba server I have. I then disabled dhcp on eth0, and rebooted the container. It came back up with no IP on eth0. winbind was running, and name resolution via wins was obviously not working. I logged in using "lxc exec bash" instead of ssh). I then just ran "dhclient eth0", and retried the name resolution (ping -c was my test), and it worked right away. So it was able to use the newly functional interface. I didn't see anything out of the ordinary in winbind's logs. I'll try again with a vm, which should be a bit slower than a lxd container. And maybe also try without a network card at all, then add one, and see if winbind needs to be restarted. In the meantime, can you perhaps grab me some winbind logs during a machine boot showing the problem? Maybe add "debug level = 3" or 5 to smb.conf as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789097 Title: winbind does not work after reboot on Mint 19 / Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1789097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

And maybe also try without a network card at all, then add one, and see if winbind needs to be restarted. In the meantime, can you perhaps grab me some winbind logs during a machine boot showing the problem? Maybe add "debug level = 3" or 5 to smb.conf as well. -- 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/1789097 Title: winbind does not work after reboot on Mint 19 / Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1789097/+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
[Bug 1789097] Re: winbind does not work after reboot on Mint 19 / Ubuntu 18.04
Just to add: the issue's the same and fully constant on an Intel Xeon E5606 @2,13GHz with 8GiB running Mint 19 Cinnamon 64-bit, and an Intel Core 2 Duo E8400 @ 3GHz withj 4GiB running Mint 19 Xfce 64-bit. That is... it's not a subtle race and I assume anyone will see this if installing only "winbind" and not the rest of "samba". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789097 Title: winbind does not work after reboot on Mint 19 / Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1789097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1789097] Re: winbind does not work after reboot on Mint 19 / Ubuntu 18.04
Yes, the network itself comes up fine. "Does not work" simply means that NetBIOS name resolution is unavailable even after it does; that e.g. "ping NAS" for "NAS" the NetBIOS name of my, well, NAS, tells me the name cannot be resolved. There would not appear to be relevant logs nor configuration files. The issue is simply that with "After=network.target" rather then "After =network-online.target" the winbindd daemon is started too early; does start, but does not work. Needs to be restarted for it to start to work. I am as mentioned on Linux Mint 19 but would be surprised if this were not the case on Ubuntu 18.04 itself as well. This is a standard, wired desktop without even wireless available. It is easy to reproduce: have the "winbind" and "libnss-winbind" packages installed but not "samba" itself, enable WINS name resolution in /etc/nsswitch.con as detailed and as normal, and reboot. As also mentioned, installing "samba" itself hides the issue by winbind having a dependency on nmbd and nmbd in turn on network-online.target; without "samba", we appear to have a simple systemd bootup race, solved by having it depend on network-online.target itself. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789097 Title: winbind does not work after reboot on Mint 19 / Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1789097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for filing this bug in Ubuntu. What do you mean by "does not work", exactly? Doesn't the network come up eventually? Or is this a desktop machine where the network is wireless and only available after someone logs in? Please show exactly what is not working, your configuration files, and also please provide logs. ** 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/1789097 Title: winbind does not work after reboot on Mint 19 / Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1789097/+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
