  installed samba4 from pkgsrc but I'm not able to connect to the shares from macOS, I just get.. "Connection failed"
• 10:56
  jzu
  something special I need to do compared to samba3 setup?
• 10:57
  jzu
  my share allows guest access and I've got guest user defined etc.
• 10:59
  jzu
  erhm this is not promising:
• 10:59
  jzu
  [root@surdo ~]# smbclient -L 192.168.1.5 -U jussi
• 10:59
  jzu
  abort_handler_s: memset_s: n > smax
• 10:59
  jzu
  Abort (core dumped)
• 12:09
  jperkin
  jzu: pstack on the core would be useful to see where it's coming from, they use memset_s a lot
• 12:10
  jperkin
  though I can immediately see at least one place where n and smax aren't the same
• 12:13
  jzu
  jperkin: p.ip.fi/Zf3c
• 12:16
  jzu
  maybe I've not set up Samba correctly as I haven't done anything else than added share which guest can access, that's all.
• 12:18
  jperkin
  possibly, but that wouldn't explain the runtime abort, the stack clearly shows n > smax but the code says they should be the same
• 12:21
  jzu
  running on latest base-64-lts, samba-4.17.4
• 12:21
  jzu
  went from 2015-something and samba3 for samb4, looking some read performance gains here :)
• 12:22
  jperkin
  ah ok I'm looking at trunk so 4.18.6, lemme check 2022Q4
• 12:26
  jperkin
  yeh looks like it was fixed in this commit: heimdal/heimdal 88ea803
• 12:26
  jperkin
  I'll look at backporting samba from turnk
• 12:26
  jzu
  thanks!
• 12:27
  jzu
  I can also switch over to latest base-64 if you're busy :)
• 12:27
  jperkin
  if you're able to verify first that the trunk version works as expected that'd be great
• 12:27
  jzu
  sure I'll do that
• 12:41
  jzu
  now the client is working, still unable to access with guest though :)
• 12:41
  jzu
  but a step forward
• 12:45
  jzu
  right so it's something in the way how macOS talks to the Samba server, as I'm able to login from the CLI on SmartOS:
• 12:46
  jzu
  # smbclient //192.168.1.5/work
• 12:46
  jzu
  Password for [MYGROUP\root]:
• 12:46
  jzu
  Anonymous login successful
• 12:51
  jzu
  right, this made mounting possible: coderwall.com/p/jbvc0a/guest-samba-access-on-mac-os-x
• 12:52
  jzu
  still not able to list shares in Network on macOS but oh well :)
• 12:57
  jperkin
  you might need some dns-sd for that, e.g. dns-sd -R SmartOS _smb._tcp local 445
• 13:00
  jzu
  I can see server there but it doesn't list shares, weird.
• 13:15
  jzu
  ah now the Guest login works through Finder, showing the shares.
• 13:29
  jbk
  i need to get back to mdns w/ smb
• 13:30
  jbk
  i have a branch where if the mdns service is running, smb will automatically register w/ it to advertise
• 13:31
  jbk
  so no dns-sd stuff is necessary
• 22:31
  copec
  Does github.com/juicedata/juicefs build under smartos?
• 22:32
  copec
  Before I try to give it the ole' college go
