Installation and Upgrades / My failed attempt at upgading from 7.1.1 to Zentyal 8.0
« on: March 29, 2024, 11:29:26 pm »
I wanted to upload a PDF attachment to show dialogue boxes with this report, but was unable to do so. The PDF was 179KB but there was no upload space.
Hope it helps
My attempt at carrying out an upgrade to Zentyal Version 8 from an up to date version of Zentyal 7.1.1
Platform: QEMU-KVM Hypervsisor host on HPE Proliant DL380 Gen9 running Ubuntu 22.04.4 LTS server with updates to 28th March 2024 including ESM updates.
VM 8vCPU, 8G Ram scsi drives on *.qcow2 2 x virtio bridge network connections
The dialogue below is misleading as it suggests that the Upgrade is finished and you can click close, but leave it open, In a separate shell monitor dpkg.log for progress ‘tail -f /var/log/dkpg.log’
Even though it will display ‘Finishing the upgrade’ watch the dpkg.log for the update finished message before clicking on ‘Close’
From dkpg.log
Click Close on Upgrading to Zentyal 8.0 dialogue and then reboot the system.
A stop job for Zentyal will delay the reboot for 1min 30sec
When the system restarted, the Zentyal logger daemon repeatedly stopped and started which might be a clue to issues ahead.
On restart, the Dashboard looked OK, but the Antivirus service failed to start. Also, the mysql service also failed due to permission issues on lock directory and missing log folder /var/log/mysql
This prevented the zentyal-core update script running to complete the install process.

Installation and Upgrades / Re: Dovecot Permission Denied stats-writer
« on: February 10, 2022, 10:17:12 pm »
FYI: I managed to cure this by the following:
# cp /usr/lib/dovecot/dovecot-lda /usr/lib/dovecot/dovecot-lda-orig <== Always make a backup
# chgrp dovecot dovecot-lda <== Change group permission to dovecot (this group has write permissions to lock file)
# chmod 2755 /usr/lib/dovecot/dovecot-lda <== Sets sticky bit so dovecot-lda is run as group=dovecot
# zs mail restart <== Restart mail (probably not needed as dovecot-lda is run on a per email basis.
See https://wiki2.dovecot.org/LDA/Postfix for details.

I had this issue a few years ago. It is a config file problem. See this Forum post https://forum.zentyal.org/index.php?topic=31998.0
Hope this helps.
Always make backup copies of the file you are changing.

Dear hshafi,
That file looks OK. However, you have not answered any of the questions regarding if the process is running "nginx: master process /usr/sbin/nginx -c /var/lib/zentyal/conf/nginx.conf", or if there are any errors reported in /var/log/zentyal/zentyal.log (you could also check /var/log/zentyal/error.log.
Perhaps you could check to see if nginx is listening on the correct ports by running 'sudo lsof |grep 8443' (without the '), you should get an output similar to: -
nginx 13303 root 9u IPv4 91944 0t0 TCP *:8443 (LISTEN)
nginx 13311 www-data 9u IPv4 91944 0t0 TCP *:8443 (LISTEN)
nginx 13312 www-data 9u IPv4 91944 0t0 TCP *:8443 (LISTEN)
nginx 13313 www-data 9u IPv4 91944 0t0 TCP *:8443 (LISTEN)
nginx 13314 www-data 9u IPv4 91944 0t0 TCP *:8443 (LISTEN)
If you do get these outputs then you should be able to get to the webadmin pages.
If you get no output, then nginx is not running. Check with 'sudo lsof' just to make sure that there are processes listening on your system
I hope this is of use to you. Please give some extra detail with your next response as it is hard to diagnose your issue without more information.

You did not mention if there were any clues in the Zentyal log file /var/log/zentyal/zentyal.log. Please look at this log as soon as you do the zs webadmin restart command
The webadmin interface is served by nginx. if you run 'ps -ef |grep nginx' (without the ' quotes) you should see output like this below : -
root 13993 1 0 May27 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /var/lib/zentyal/conf/nginx.conf
www-data 14001 13993 0 May27 ? 00:01:19 nginx: worker process
www-data 14002 13993 0 May27 ? 00:00:00 nginx: worker process
www-data 14003 13993 0 May27 ? 00:00:07 nginx: worker process
www-data 14004 13993 0 May27 ? 00:00:26 nginx: worker process
If you do see the above, can you send the contents of /var/lib/zentyal/conf/nginx.conf to check the settings?

Can you check /var/log/zentyal/zentyal.log for any clues/errors?
Do you get any errors when doing the zs webadmin start?
For example : * Restarting Zentyal module: webadmin [fail]
Error loading class: EBox::SysInfo error: Global symbol "$lastVersion" requires explicit package name (did you forget to declare "my $lastVersion"?) at /usr/share/perl5/EBox/SysInfo.pm line 330.

Contributions / Tips&Tricks / Features Requests / Suggestion to improve output of smart-admin-report
« on: April 09, 2020, 11:53:23 am »
Thanks to Zentyal briefing to use this feature in the Community version.
Suggested updates to /usr/share/zentyal/smart-admin-report: -
########
## Server packages
########
Issue, the report states that there are 1 upgradable packages available when there is no packages in that state.
Line 140: Change "apt list --upgradable 2> /dev/null | wc -l" to "apt list --upgradable 2> /dev/null|awk '{if(NR>1)print}' | wc -l"
###################
# Antivirus module #
###################
Issue, Last ClamAV database update: the output is blank

This will detail the database date of the current signatures.
Tested successfully on Zentyal Community Edition Version 6.1.2 running on Ubuntu Linux 18.04.3, running as a VM on Hyper-V.

Installation and Upgrades / Re: Webadmin not Accessible
« on: December 10, 2019, 07:15:39 pm »
If you run 'sudo netstat -tulpn | grep nginx' you should get the actual port that you need to connect to,
My example is
"tcp 0 0 0.0.0.0:8443 0.0.0.0:* LISTEN 9189/nginx: master"
So try connecting to your internal IP address with https://<internal_ip>:8443/ and see if you get the webadmin login screen.

I can confirm that the Dashboard only shows users logged into the system either on the console or via a SSH connection. I can't throw any light on the roaming profiles issue.

Installation and Upgrades / Re: SOGo not working after update to Zentyal 5.0.1
« on: August 23, 2018, 04:20:05 pm »
Update:
I have modified /usr/share/zentyal/stubs/sogo/SOGo.conf-apache.mas and changed the line: -
RequestHeader set "x-webobjects-server-url" "https://%{REQUEST_HOST}e:443"
to: -
RequestHeader set "x-webobjects-server-url" "https://%{REQUEST_HOST}e"
Then restarted "SOGo Webmail" from the console.
I made a copy of SOGo.conf-apache.mas before making any changes just in case I made an error.
Hope this helps
Thanks to a CZ site with the answer http://www.abclinuxu.cz/poradna/linux/show/438278

It would be nice to have a cure, but I ran out of time researching where this NULL addition gets added

« on: May 29, 2018, 07:05:24 pm »
Firewall logs normally log dropped/rejected packets as a standard. You should see e-mails by locking at the Mail logs (assuming it is enabled), or you can monitor /var/log/mail.log to see connections made to your mail server. mail.log will show all connections to ports 25, 587, as well as IMAP and POP connections.

Email and Groupware / Re: Received Email marked helo command rejected need fully qualified hostname
« on: May 29, 2018, 06:58:00 pm »
Zentyal uses Postfix as it's Message Transport Agent (MTA). Normally legitimate e-mails from the Internet will always have a FQDN format. Local PC's or compromised PC's generally will just send the PC name. The restriction is contained in the configuration file /etc/postfix/main.cf and the restriction is reject_non_fqdn_helo_hostname. This file is created from a master config file main.cf.mas in the folder /usr/share/zentyal/stubs/mail. Always make a copy of any file you modify before modifying. I tend to create a copy with the date. e.g. cp main.cf.mas main.cf-29052018. In my version of Zentyal 5.1.1 the line to be removed is line 48 "$smtpRecipientRestrictions .= 'reject_non_fqdn_helo_hostname, ';"
After you have changed the line, restart the mail server and check that the reject_non_fqdn_helo_hostname is missing from the new file /etc/postfix/main.cf.
Hope this helps you.
