[pcmanfm] [SAMBA] - Can't browse workgroup, can connect directly

aphirst · 2017-08-29 08:03:07

Server runs Arch ARM, this client runs normal Arch. Other clients on the network seem to have no issues with the setup, so I think the issue is indeed confined here. I don't have any Windows machines currently, and while our router does offer support for sharing a single USB device via samba, there's no real ability to configure it or diagnose it beyond merely specifying what its WORKGROUP and DEVICE names should be, and "enabling/disabling" samba sharing.

pcmanfm is able to connect to my samba shares directly, both via smb://servername/share AND smb://xxx.xxx.xxx.xxx/share. However, when I go into the Network view, either pcmanfm hangs entirely until it reaches its timeout, or I get the "Windows Network" subentry, clicking on which simply yields nothing (though does not "hang" the application).

I also have the same shares mounted directly to /mnt subdirectories via cifs entries in /etc/fstab which works fine too.

I'm not really sure how to proceed from here, so I figured I should make a forum thread. Below I've posted the trimmed (via testparm) smb.conf from the Server and the Client. If there's anything else which would be worth sharing, just let me know.

I'm having the same issue with my domain network, samba 4.7.3. Everything else works great. Can connect to netbios names and FQDNs, authentication is fine, getent passwd/group returns the names on my domain controller .... can't browse shares. my smbtree only returns a few results, too, even though I can connect to the ones it doesn't return. It's pretty weird...

Have you gotten anywhere with this?

Thanks!

Hi all,

I have the same issue. I can browse shares directly, I can view shares by using smbtree, but when I want to show entire workgroup I get an error message. What is even more interesting I have 2 workgroups in my networks and one can be browsed and shows hosts, while second one does not...

Has anyone encountered such a problem? What can I share to help with tracing the issue?

Thanks!

I found a "fix" for this: since samba 4.7 the default value of client max protocol changed to "SMB3_11".
I added on /etc/samba/smb.conf this:

client max protocol = NT1

Then restart the computer (looks like restarting smbd and nmbd isn't enough). It seems to work on any file explorer.

Thanks The Loko I confirm this working. Now when I browse workgroup it works fine. I will only add that the change is only required on client side. Server does not need this change.

However I do not understand why it is working. smbtree shows proper list of hosts and shares, I can access shares without a problem without adding this option, however I cannot browse workgroup. In addition only workgroup in which host uses samba under archlinux does not work. Workgroup with windows hosts only works fine. This seems to be a Thunar issue, I see no other option. I will see if I can find whether it can work with SMB protocol > 1 what seems to be the issue.

Thanks for finding this workaround!
