Apparently I missed a step somewhere! On DC01 /etc/systemd/resolved.conf says [Resolve] #DNS= #FallbackDNS= #Domains= #LLMNR=no #MulticastDNS=no #DNSSEC=no #DNSOverTLS=no #Cache=yes #DNSStubListener=yes #ReadEtcHosts=yes On DC02 it reads [Resolve] DNS=8.8.8.8 FallbackDNS=8.8.4.4 #Domains= #LLMNR=no #MulticastDNS=no DNSSEC=no #DNSOverTLS=no #Cache=yes #DNSStubListener=yes #ReadEtcHosts=yes So the DNS line should be the...

Getting rid of netbios does not mean you should not configure it. You "should" configure it. And even if you disable WINS, LLMNR is still running, so you gained.. .. Nothing with disabling WINS. Just in this case make sure your NETBIOS names obey the DNS rules and https://support.microsoft.com/nl-nl/help/909264/naming-conventions-in-active-directory-for-computers-domains-sites-and Also, if using CIFS (SMB) to access any...

Hi, I hope this hasn't already been discussed to death, but I didn't find the answer through Google. In short, my question is: how can I advertise a Samba server through UPnP/Network Discovery? I'm currently using Samba 3.2.6, but should be able to upgrade if needed. I am trying to build an IPv6-only network, for now just for testing purposes. The problem I am having is that

running Version 3.6.23-14.el6_6 I'm having slow save times with folders names ~something.. ie. /www/~bin/content.txt. doing this via a windows share.. when I save file it has a moment (few seconds) of hesitation.. then saves. When I do /www/bin/content.txt. the file saves instantly. Is there anywhere I can change a setting to fix this? or is this a bug. I've looked in the logs

Hello, We have Samba 4.0.21 running on a Linux machine with a share configured. It doesn't show in Windows 10 "Network" listing of available shares, unless I turn on SMBv1 in the Window features (and reboot). Accessing the share by IP or hostname works, even with SMBv1 disabled on Windows 10. Windows 10 is of the build 1804. Is enabling SMBv1 on the Windows 10 side the only

Thank You Rowland. I did it like You say, killed avahi, added the record without domain suffix, but nothing changed, and the record seems no different compared to other records added with the suffix some time before. My Samba DNS record looks like this (and I see nothing special in there):   Name=, Records=3, Children=0     SOA: serial=39, refresh=900, retry=600, expire=86400, minttl=3600,

...x. See RFC 6724 and RFC 6555. These two RFCs do not provide the full answer. I would strongly recommend IPv6 training, such as ours (see www.ipv6training.com <http://www.ipv6training.com> ) as this is far from simple. It makes IPv6 consultants very happy though. 😉 >What about mDNS?
