Brother MFC-T920DW printer setting - [SOLVED]

I have made some cleaning on the system and I have reinstalled both Windows 11 and Arch. After installing the brother-mfct920dw package, when trying to add the printer I get the error message

Unable to connect to BRW3C0AF380382D.local:631: Name or service not known

The avahi-daemon is running, the /etc/nsswitch.conf hosts line is modified to include

mdns_minimal [NOTFOUND=return]

before dns. The /etc/hosts file is 

 127.0.0.1    localhost.localdomain	localhost
::1    localhost.localdomain	localhost

127.0.1.1	 opticlock.localdomain	opticlock

Any hint is welcome. Thank you.

Have a relaxing WE smile

Re: Brother MFC-T920DW printer setting - [SOLVED]

nmap BRW3C0AF380382D.local

Returns

Failed to resolve "BRW3C0AF380382D.local".
WARNING: No targets were specified, so 0 hosts scanned.
Nmap done: 0 IP addresses (0 hosts up) scanned in 0.56 seconds

I also tried to resolve domain name and 

nslookup inflpr.ro

gives

Re: Brother MFC-T920DW printer setting - [SOLVED]

resolvectl status

delivers

Failed to get global data: Could not activate remote peer 'org.freedesktop.resolve1': activation request failed: unknown unit

while

systemctl status systemd-resolved

returns 

systemd-resolved.service - Network Name Resolution
     Loaded: loaded (/usr/lib/systemd/system/systemd-resolved.service; disabled
     Active: inactive (dead)

All I had to do was to enable the systemd-resolved service, which solved my issue

systemctl enable --now systemd-resolved

 

Thank you Seth, much obliged. smile cool

Re: Brother MFC-T920DW printer setting - [SOLVED]

Actschually™ resolved would get in the way - are you sure avahi-daemon.service is running?

systemctl status avahi-daemon.service

avahi-browse certainly  had no issues at finding the services and now the resolved mDNS responder will resolve the .local domain (which isn't an issue as long as you just want to resolve domains but I'm not sure whether service and notably cups already works w/ it if you survey printers in the future)

Re: Brother MFC-T920DW printer setting - [SOLVED]

As odd as it seems, but one of the first things I have checked was to make sure avahi-daemon.service was running. It is active, as well as the cups.service daemon.

Re: Brother MFC-T920DW printer setting - [SOLVED]

Did resolved change the resolv.conf in any way?
Resp. what's now the output of "resolvectl status"?

Re: Brother MFC-T920DW printer setting - [SOLVED]

I will be not at office for a few days, but I have observed the same issue at home. The printer at office, Brother MFC-T920DW was operational last week when I have installed it, as it is a new one. Now, CUPS does no longer see my printer at home  (Brother MFC-J3930DW) and gives me the error message

Unable to locate printer "BRWF889D2A4AE15.local
nslookup digi.ro

returns

Server:		100.100.1.1
Address:	100.100.1.1#53

Name:	digi.ro
Address: 81.196.1.152
Name:	digi.ro
Address: 81.196.1.156

while

sudo lpinfo -v

           

outputs

network https
network ipp
network http
network ipps
network beh
file cups-pdf:/
network socket
network lpd
network smb

So, the following lines are missing

network dnssd://Brother%20MFC-J3930DW._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-b422005f0bdc
network lpd://BRWF889D2A4AE15/BINARY_P1

cups.service and avahi-daemon.service are up. 

avahi-browse --all --ignore-local --resolve --terminate

returns

 cat /etc/resolv.conf

yields

nameserver 100.100.1.1
nameserver 100.100.0.1

I think there is an issue either with avahi or systemd-resolved.

Re: Brother MFC-T920DW printer setting - [SOLVED]

"nslookup digi.ro" isn't relevant here, that's a public domain (and likely your ISP)
Your problem is the inability to resolve BRWF889D2A4AE15.local which uses mDNS (aka "avahi" aka "bonjours") where the weird part is that avahi-browse acatually finds those domains

https://archlinux.org/packages/extra/x86_64/nss-mdns/ hasn't been updated in over a year
https://archlinux.org/packages/extra/x86_64/avahi/ however just has been and should™ be safe to downgrade for a test - I suspect it became incompatible w/ the older nss-mdns versions.

The last contender would be glibc, do NOT! "just" downgrade that in isolation - we'll look there if it's not avahi.
