Problem with nsdc: socket.error

Support
#1

NethServer Version: 7.5.1804 (final)

Dear Nethservians,

I have stumbled upon a problem with nsdc which i probably created myself :frowning: I cannot add new users in Nethserver and also the hotsync configuration-backup encounters a problem. I think it is python related because some time ago I tried to install Odoo (following to the instructions in a forum-post), which requires python version 3.5 while Nethserver has 2.7 on board. Around that time the above problems started. I didn’t get Odoo to work so in the mean time I erased python 3.

This is an extract of the messages log for the config-backup:

The errorlines for adding a user are similar in respect to the socket.error. What could I try to resolve this problem? All help is much appreciated!

Regards, Wijnand.

Restore configuration data error

I tried to reproduce but got no error, I installed AD and odoo 11 which uses python 3.5. Even after reboot I can still create users or do a config backup.

Is the nsdc running?

systemctl status nsdc -l

Hi Markus,

nsdc seems to be running:

One of the error-lines refers to so.connect(’/var/lib/machines/nsdc/var/lib/misc/nsdc-run.sock’) but the nsdc-run.sock file is not present in that directory.

Try the following commands:

systemctl stop nsdc
systemctl start nsdc

Hello Davide,

Unfortunately restarting nsdc doesn’t lead to success. nsdc is running but the socket.error still exists.

systemctl stop nsdc:

You could try also

 systemctl stop -M nsdc nsdc-run.socket
 systemctl start -M nsdc nsdc-run.socket

(Re-)Executing this action might help too

/etc/e-smith/events/nethserver-dc-upgrade/S30nethserver-dc-upgrade
#7

First of all, thanks for your effort in helping me out!

Still no luck i’m afraid. The compete output of the commands is in a file because of the size (seems too large to include in a forum message). How can i get it to you? There is a lot of activity going on after issuing the S30nethserver-dc-upgrade command. I did a reboot after the dc-upgrade to be sure but that didn’t help either.

For completeness I’ve added the logoutput after adding a user in Nethserver, same problems concerning the missing nsdc-run.sock and the user adding fails.

Please upload it to https://gist.github.com/ (can choose both public/private). You can PM me if you like!

Hopefully this works, I am new to this :grinning:

#10

I noticed that you updated from an old ns-samba version (4.6.11)

https://gist.github.com/pa3hfj/83a08dff3a2a910b81168cdc4d61323e#file-gistfile1-txt-L157

The update seems ok, however…

https://gist.github.com/pa3hfj/83a08dff3a2a910b81168cdc4d61323e#file-gistfile1-txt-L729

Failed to execute operation: No such file or directory

Try to execute again

systemctl -M nsdc enable --now nsdc-run.socket

…just to see if the error is the same.

#11

The results:

[root@server1 log]# systemctl -M nsdc enable --now nsdc-run.socket
Failed to execute operation: No such file or directory

I must add that according to the Software Centre updates-tab the system was up-to-date before nethserver-dc-upgrade command, apart from two entries that are there for a long time (far before this problem arose)

Naam 	Versie 	Release

The update transaction was acting on the NSDC container chroot, not the host system

Please try this command

signal-event nethserver-dc-upgrade

It also expands some templates I might forget in the commands above…

Check how it goes in /var/log/messages

Hello Davide,

Well, i’m very glad to inform you that this command did the trick! :fireworks:

This solved it, there seemed to be a missing symlink:

server1 esmith::event[20584]: Created symlink from /etc/systemd/system/sockets.target.wants/nsdc-run.socket to /etc/systemd/system/nsdc-run.socket.

Davide, thank you very much for your perseverance!
