Hi,

I updated some packages today and rebooted the server, I can not access Flexshare Shared directories anymore.

/var/log/messages

Instead of downgrading, can someone who is experiencing this issue try the following:

Please test modifying the line in /etc/samba/smb.conf to be the following:

allow trusted domains = yes

This is for those that are using ClearOS as a NAS with no domain logons.

I'm curious to know if this fixes the Samba issue reported with the update.

    Confirmed there is an issue... Updated a file server to the 7.5 that was just released and sure enough Windows 8.1 and Windows XP clients (no Windows 10 here) can no longer connect to the samba shares. No problem existed with 7.4. More interested in watching NASCAR and the Silverstone GB F1 practice 3 and qualifying - so debugging. if any, will have to wait...

    From my testing samba is broken and you have to roll it back but the files aren't there. Luckily I have a Business licence which has not upgraded so I've pinched all the packages from there (apologies devs) and I've uploaded them to my server here. I only have 3mbps upload so don't all hit me at once, but you need to download all the 20 packages from there. Someone else can write out the whole wget string!

    Then from where you have downloaded them to do a:
    yum downgrade dbus-1.6.12-17.el7.x86_64.rpm dbus-libs-1.6.12-17.el7.x86_64.rpm dbus-x11-1.6.12-17.el7.x86_64.rpm libldb-1.1.29-1.el7.x86_64.rpm libsmbclient-4.6.2-12.v7.1.x86_64.rpm libwbclient-4.6.2-12.v7.1.x86_64.rpm pyldb-1.1.29-1.el7.x86_64.rpm samba-4.6.2-12.v7.1.x86_64.rpm samba-client-4.6.2-12.v7.1.x86_64.rpm samba-client-libs-4.6.2-12.v7.1.x86_64.rpm samba-common-4.6.2-12.v7.1.noarch.rpm samba-common-libs-4.6.2-12.v7.1.x86_64.rpm samba-common-tools-4.6.2-12.v7.1.x86_64.rpm samba-dc-4.6.2-12.v7.1.x86_64.rpm samba-dc-libs-4.6.2-12.v7.1.x86_64.rpm samba-libs-4.6.2-12.v7.1.x86_64.rpm samba-python-4.6.2-12.v7.1.x86_64.rpm samba-winbind-4.6.2-12.v7.1.x86_64.rpm samba-winbind-clients-4.6.2-12.v7.1.x86_64.rpm samba-winbind-modules-4.6.2-12.v7.1.x86_64.rpm
    And samba should be working again.

    For completeness also do:
    yum remove python-dns


    The next thing is to block the packages from updating again until notified that they are safe. As a quick and dirty hack edit /etc/yum.conf and add a line:
    exclude=samba*
    This will probably stop all updates because of dependency issues. The proper way would be to list the 20 packages in the exclude line, comma separated (I think). This would allow other packages to update in the nightly run.

    Please can somebody test and report back.

    Thank you.

    Samba/Flexshare is working again.

    I mirrored the samba packages here (Gigabit Connection)

    gzip of all files

    wget command to get them all :
    wget -r -e robots=off --wait 1 --no-parent http://blue-pyramid.com/smb

    Are you using Domains? If not, have you by any chance set the parameter "Windows 10 Domain Logins" to enabled? If you are not using domains, please disable it.

    Thank you for your reply,
    Just disabled the Windows 10 Domain logins, restarted the smb service. Still facing the same issue.
    Don't know what caused this, I only updated the packages using yum, did not change smb settings at all.

    What version of ClearOS are you running and what is your directory server (LDAP/Samba/AD Connector)?

    Yes, Many times.
    - I tried to undo the yum update, using yum history, failed.
    - I restored config backup of few days ago, Didn't help.
    - I commented out the usermap file path in smb.conf, didn't help

    2 friends of mine have faced the same after the recent update.

    Dave has responded in the US but he needs to sleep. I may try looking at is on a spare machine (my main box is Business so does not get the updates for a couple of weeks).

    I notice my /etc/samba/smbusers is missing on my Community box. As a quick hack, can you try setting up an /etc/samba/smbusers file and put in it:
    # Unix_name = SMB_name1 SMB_name2 ...
    root = administrator admin
    nobody = guest pcguest smbguest
    This is my file from business. My permissions are root:root, 0644 so probably won't need changing.

    Mine was missing too, tried the above, still can't access shares, Downloaded some backup archives from gui and checked inside them, there was no smbusers file in any of them and flexshare was working fine without that file, so it seems that something else causing it.

    Then I changed smb log level but there's nothing helpful in the log file.

    I don't know how they are managing the repos, but it looks like all the old samba packages have been removed so there is no possibility of downgrading it :(

    Hi Nick,
    Same issue here. I do not use Windows 10 Domain Logins, so I switched it off. But it doesn't help. Every package is updates.
    is there any information I could help you troubleshoot with?

    My concern is the devs had issues compiling Samba and it took a while before they could. I wonder if there were incorrect compile options used. I was trying to downgrade but could not and the installation disk does not contain the samba packages.

    The samba package is the same as was in the original beta, but I did not look at its filesharing. If anyone else did then samba may not be the cause. More recent updates which come to mind are the openldap ones and these can be downgraded with:
    yum downgrade openldap openldap-servers openldap-clients
    If that fixes it then we'd need to temporarily block the upgrade overnight.

    I downgraded openldap packages, restored 2 days ago config files from backup but the issue is still there.

    EDIT: Now docker does not start on boot!

    Just do a "yum update" to get them back to the latest.

    ..... and I have a solution in the next post.

    I'm having difficulty replicating the issue on my systems.

    This is good and bad news. Good because it can be demonstrated that the update isn't broken across the board. Bad because I don't know the cause of it.

    I'm going to try on an older Business edition I use in production.

    I've tried with a second system (an older ClearOS Business downgraded to ClearOS Community) the updates seem to work fine. To be clear, I've tested using my Mac and am now working on standing up a new windows 7 system (my old vm is borked for some reason) to see if it has issues.

    I am seeing issues with my Windows 10 box but that could be from the 1803 issue.

    Win10 should be OK if you do not enable "Windows 10 Domain Logins". SMB3 will then be used. If you have not enabled this then you have probably reproduced the issue. The only reason I mentioned Business is because that was the only place I could get the old packages from.

    @Ata,
    Thanks for mirroring. It looks like the forum does not like the "-" in your domain name and it completely broke the URL formatting. I've changed it to a %2D and it seems to be OK now. I'll have to raise a bug against the forum.

    @Nick

    I noticed this problem today when I tried to sync some files from my Android (v4.1) tablet to the COS server. SMB isn't connecting within some apps (Total Commander & Folder Sync) but VLC does connect for some reason. Our Macs running OSX 10.11 through 10.12 can connect OK. We don't have any windows boxes (expect in VMs) so can't comment on those.

    Not sure if this helps in some way to narrow down the issue and repeatability.

    Thanks for posting the solution. I'll downgrade the files as everything worked fine prior to this mornings update.

    **edit** I've just noticed that the smbuser file is not available either. Will look into this.

    Also thought I should add the error log from the Android trying to connect

    The lack of the smbuser file is a red herring. Always has been. We don't use it and samba complains now and again about it missing.

    I only went down that route just in case. I was clutching at straws this morning. I have the file which must have copied over from my 6.x to 7.x upgrade, but the others were missing it (hence the message)

    WARNING! While the solution of downgrading Samba works on a fairly vanilla ClearOS system - there are cases where it will not. The ClearOS systems here have a large number of additional rpms installed including some dependant on the dbus-libs. They were upgraded together with the upgrade to dbus and therefore cause the downgrade to fail the yum check as they are now dependant on the newly up-graded dbus. Would be possible to work out the additional rpms to be downgraded and find them - but this feels like it's opening Pandora's box.

    The solution here was to create a Samba "proxy" using a ClearOS 6.9 box... it is a client to all the shares on the upgraded7.5 box, these are then in turn shared to provide access for the Windows boxes. Extra traffic but with very few Windows machines and the fact they are not used that often quite workable .

    Just checked with a Windows 7 machine - it is NOT able to access the upgraded ClearOS 7.5 shares, just like the Windows XP and 8.1 boxes are unable to do so.

    Yay- YES - Windows 7 now connects to the upgraded 7.5 ... will turn on the 8.1 and XP machines and update this append - thanks for the hard work...

    Update: Yes changing to "allow trusted domains = yes" has fixed the problem for Windows XP and 8.1 as well. Thanks Dave

    I'm curious to know if anyone is experiencing this issue if joined to the domain on an upgrade. My suspicion is no. My hypothesis is that this only affects those that use the flexshares in non-domain join modes.

    It took me a bit to get the lab set up to replicate the problem and when I got it all done the error messages weren't specific enough so I cranked the log level to 8 and read through both a working 7.4 log trace for the same activity vs. a 7.5 and this is the nugget that I found:

    At first, I thought that there was an LDAP problem because of the unmatched users bit but then I reasoned that this would NOT be the case since Linux and Macs are working fine so it cannot be that. I also thought that perhaps that the match was an issue but I can see elsewhere in the logs that the match is happening to LDAP. The key was just below where the domain was rejected. The domain, 'dloper-PC', is the machine name of my test computer which I purposefully did NOT join to the domain. So this means that it was rejecting based on the lack of a computer account which is supposed to work based on the NAS model. I then googled a bit to see if that error was known to the samba community. I couldn't find any articles related so I decided to troll through the smb.conf file and the line just stood out to me for some reason.

    allow trusted domains = yes

    BTW, you only need to change this in the file, you don't need to reboot or restart samba for this to go into effect.

    I've tested Dave's solution and it works for me - Win10 (1803). I've rejected my post in this thread as being the Accepted Answer and Accepted Dave's. I've also posted to the main thread.

    FWIW the repo management is not working well. There was no way to downgrade. It looks like there is also a new installation where the user is unable to install from the marketplace, because his system has not upgraded yet and the lack of old packages is causing dependency problems.

    @Tony,
    I could not hope to cover all bases with the downgrade. Even to get to where I got with the packages I had to do a dummy upgrade of a Business box to work out all the packages it needed then I download each one with yumdownloader. It is quite possible I picked up more packages than I needed but were needed for that particular set up (e.g. python-dns?). I then tried the downgrade in a VM. That worked so then on my test Community box and I was able to map the drive. It could have been a case of dependency hell!

    Sadly, this did not fix the problem for me. I've had to revert back to Nick's temporary solution.

    Update: Seems i had to wait for a while, but its working now.

    It looks like this setting as yes or no does not affect computers joined to the domain but only those in NAS mode. I'm going to suggest that this parameter be flipped to Yes on all configs during the upgrade process.

    The default value, if omitted, is "yes" so it is worth flipping if it is set (newer installations). It may not be worth setting on older installations (like my 6.x -> 7.x backup and restore) as it isn't in the config file at all. Belt and braces says set it anyway.

    Hello guys,

    Is there any news about that issue? It was located the root of the cause?

    Thanks for all this information I could fix my server and taking back Flexshare and Samba.

    The root cause seems to be that Samba changed how the parameter was working. It now should be set to "yes" or deleted completely. It may have originally been caused by a misunderstanding on how the parameter should have been set in the first place, but it does not matter now. Updates should now be automatically setting the parameter to "yes" if it exists.

    Hello all!

    Well, first of all, sorry for the spam. But I have been digging a little bit more into the issue. First of all... message from logs when I try to start Samba from Web

     webconfig: Redirecting to /bin/systemctl start samba.service
    Failed to start samba.service: Unit not found.


    Look there is not samba.service within "/usr/lib/systemd/system", however, I can find smb.service instead.

    Can you check guys in yout configuration?

    Sadly that didnt work for me. "allow trusted domains = yes" is set and my samba does not start and I also lost the DNS server. Thankfully I have a snapshot but I dont want to give up.

    Thanks agagain!

    I've deleted your duplicate post. As you've now had two posts approved by the mods they should now automatically appear.

    It sounds like you have more than one problem.

    For DNS, please do a:
    systemctl restart dnsmasq.service
    Then look in /var/log/messages for errors.

    For Samba, please can you do a:
    systemctl status smb.service
    systemctl status nmb.service
    systemctl status winbind.service
    Then try starting any not running (not sure about winbind - it depends on your set up) and have a look in the logs (various including in /var/log/samba/)

    Please can you also check slapd is running with a:
    systemctl status slapd.service
