Installation and Upgrades / 3.16.0-52-generic
« on: November 06, 2015, 12:42:41 am »
I've just done a reboot following the kernel upgrade to 3.16.0-52-generic and I had the 'ip' and 'cut' processes running/hovering at 99% and 73% CPU usage respectively. I wasn't able to get virtualbox webservice working either

Code: [Select]
/etc/init.d/vboxweb-service start
Starting VirtualBox web service ...fail!

The box seemed responsive & the web interface came up despite this.. As I rely on the virtualbox instance, I rolled back to the previous kernel and all seemed OK. Anyone else experienced this ? I had a look for kernel errors reported by non-zentyal ubuntu users but couldn't find anything.

Posting this in the hope that it helps someone else. The latest kernel update broke the networking on a primergy server that I manage, as reported here. Network connections were randomly getting reset (every 30s or so) with the following messages recurring in dmesg

Code: [Select]
[ 3209.384430] igb 0000:02:00.0: Detected Tx Unit Hang

[ 3211.385464] igb 0000:02:00.0: Detected Tx Unit Hang

So I proceeded to downgrade the kernel to the previously working one. I got the list of the kernels installed on the server using

Code: [Select]
sudo dpkg --list | grep linux-image
The most recent one installed was linux-image-3.16.0-48-generic and I proceeded to remove the offending kernel image using

Code: [Select]
sudo apt-get purge linux-image-3.16.0-48-generic
and rebuilt grub so that it picked the most recent kernel still installed on the system after removing 3.16.0-48 (linux-image-3.16.0-46-generic)

Code: [Select]
sudo update-grub
After rebooting, the server came back up and worked normally. Currently kernel upgrades are halted until I re-install linux-image-generic-lts-utopic which was removed as part of the kernel downgrade. To get automatic kernel upgrades working again re-install linux-image-generic-lts-utopic. I'll re-attempt the kernel upgrade when .48 is superseded & post again. Status of this bug: "Fix Committed", meaning that the bug will be fixed but a fix will not be available until next kernel release.

Installation and Upgrades / WINS server without DHCP?
« on: August 11, 2015, 12:15:55 am »
Simple question, does Zentyal 4.1 have a WINS server function without enabling DHCP? If not, how are windows network names resolved ?

Installation and Upgrades / NetBIOS over VPN
« on: July 22, 2015, 08:22:18 pm »
Using Zentyal 4.1.3. Until recently the name resolution was working over VPN without issue, although the nmbd service wouldn't start automatically. I followed the suggestion here to get it to autostart at boot (which didn't work incidentally). I have since reverted the changes, rebooted the server but still cannot access the server/samba using the network name over a VPN connection. I've also tried removing and recreating the network object, removing and re-adding the advertised networks in the VPN configs.

nslookup of the network name on the server gives the correct IP. IP access to the samba shares works fine. Setting the server name and IP in the local hosts file works, but using the server name without doing so returns nothing. Before I start breaking out the backups, PLEASE does anyone have suggestions how I can fix this ?

I was very disappointed to find that the samba user info that used to get logged to the management pages has been removed from the recent Zentyal versions. I wanted to restore this very useful diagnostic function and so looked for an alternative method to create a similar web-based log.

Prerequisites;
You need apache2 installed and configured > https://wiki.zentyal.org/wiki/Apache_web_server

Basic version;
Use smbstatus to dump its output to a text file that you open in a browser. Make a folder called smbstatus in /var/www/html/

As root, create a cron job (crontab -e) that looks like this;

* * * * * smbstatus > /var/www/html/smbstatus/smb.txt

This will pull samba info once per minute and dump it into /var/www/html/smbstatus/smb.txt

(if you want it to be updated more often than once per minute, you can create a bash file that calls 'smbstatus > /var/www/html/smbstatus/smb.txt' and then 'sleep 15' i.e. wait for 15 seconds' and call smbstatus again, sleep, repeat.. and call that bash file from crontab instead)

You can then access this via;

http://your.server.address/smbstatus/smb.txt

You'll probably want to restrict access to this folder by creating an htpasswd and adding an .htaccess file;

I'll post up the PHP version shortly :)

Installation and Upgrades / Zentyal Dash - Samba Users
« on: May 13, 2015, 11:34:58 am »
Hi,

There was an excellent feature of Zentyal 2.2 that showed a list of the active users connected to Samba. It's there a way of enabling this or an alternative way to view realtime samba user data ?

Cheers !

Installation and Upgrades / OpenVPN routing issues [SOLVED]
« on: May 12, 2015, 05:57:31 pm »
Zentyal 4.1, new install.

If I open a VPN connection to the server, I completely lose connection to my local network (gateway, proxy server, other PCs etc). I cannot ping another machine until the VPN GUI is disconnected and closed again. I cannot access the proxy server again until I disconnect and reconnect the ethernet cable (ping > 'General failure' - WTF?!). This is not how OVPN on Zentyal used to work. Is this normal behaviour for 4.1 ?

The only difference between the two configs is
Code: [Select]
# Allow remote peer to change its IP address and/or port number
float

Commenting this out makes no difference.. I'm using the same version of OpenVPN GUI so the difference must be in the server config..

Hi,

Zentyal 4.1, I have the openVPN set up and clients are able to connect to the server. When the client connects though, while they can access the network shares etc on the server, they cannot access the internet.. Incidentally there is often

Code: [Select]
UNDEF <GatewayIPAddress>:58556 Tue May 12 10:30:19 2015
appearing in the admin pages on the server. Any ideas why all traffic is either being routed via the VPN and rejected or not routed at all ?

Hi All,

Just a quick note of experience to the forum that might help in the future.. Machine (fresh install of 4.1) set up and working on one network range, then take it to its' new network, expecting that I would change the static network address at the new location. Before taking it I'd tried changing the static IP to the new network scheme but was told by zentyal that it could not see the network and so wouldn't change the settings (and so I presumed I could just plug into the new network and change the settings once there).

Booting the machine up allowed me to log in to the desktop, and if I was quick I could log in to the management page at https://localhost:8443 but was unable to make any changes as the GUI would hang and eventually return an nginx gateway error 504. Not got any experience with nginx or I'd have had a tinker. Checking via command line zentyal network, firewall, webadmin were running.. restarting webadmin via the command line hung and returned nothing. zentyal.log didn't show anything untoward. Couldn't get any further.

Took the server back to the network it was installed on and everything worked without changing anything. Luckily the server had a second network port, so I configured them both to static IPs and complimentary gateways. When I took it back to the new network (and connected to the correct ethernet port) I was able to get the GUI working again. If you're in a similar situation with one network port, set it to DHCP, take it to the new network, boot and then login locally to the desktop and change it to the static IP you wanted in the first place!

nginx/error.log
Code: [Select]
2015/05/11 09:06:40 [emerg] 2786#0: bind() to 0.0.0.0:8443 failed (98: Address already in use)

2015/05/11 09:06:40 [emerg] 2786#0: bind() to 0.0.0.0:8443 failed (98: Address already in use)
2015/05/11 09:06:40 [emerg] 2786#0: bind() to 0.0.0.0:8443 failed (98: Address already in use)
2015/05/11 09:06:40 [emerg] 2786#0: bind() to 0.0.0.0:8443 failed (98: Address already in use)
2015/05/11 09:06:40 [emerg] 2786#0: still could not bind()

Even though I was using https://localhost:8443 zentyal seemingly refused to route the traffic if there was no connection to the network gateway.. Although the log suggests that it's trying to bind nginx to a port that already in use, presumably nginx itself...

Installation and Upgrades / Guest access warning [SOLVED]
« on: April 30, 2015, 12:48:14 pm »
Hi All.

I have a fresh install of Zentyal 4.1 and am currently setting up samba shares. I created a shared folder and ticked 'guest access' for that share (recursive ACL was enabled by default) and got the warning;

Quote
Domain guest account should be enabled for guest access to shares. You can enable it in the users and groups manager.

So I enabled the guest account, but when I went back to the 'File Sharing' section I am still getting the message. I cannot remove this warning. So far I have tried removing the shared folder, disabled guest account, re-enabled guest account and I still get the message. How do I get rid of this ?

Installation and Upgrades / No screens found - lxdm
« on: July 15, 2014, 04:27:33 pm »
Hi,

I recently rebooted my Zentyal 2.2 64 bit server, but when it came back up LXDM refuses to start. Checking out the lxdm.log shows;

Code: [Select]
(II) [KMS] Kernel modesetting enabled.
(EE) RADEON(0): No modes.
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

Please consult the The X.Org Foundation support
         at http://wiki.x.org
 for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional information.

 ddxSigGiveUp: Closing log

Normally at this point I'd start poking about with /etc/X11/xorg.conf, but it appears Zentyal doesn't use it... nor can I find anything in the documentation how lxde/dm is configured in Zentyal.

Here's the full /var/log/Xorg.0.log

Installation and Upgrades / Safe to remove amavis user ?
« on: March 02, 2012, 02:58:54 pm »
I have lots of errors logged in the postgresql logs for the mailfilter and amavis authentication. This started after re-installing the users and groups module, the amavis user authentication has not worked since. The amavis user does not appear in the UI list of users, I can't find the amavis user in the LDAP database either.. Removing the module leaves the user in /etc/passwd which then appears to conflict with re-installing the mailfilter module.. I want to remove the user so it can be recreated when the zentyal mailfilter module is re-installed.

N.B. The same appears to be the case for the roundcube user, and problems I had re-installing the webmail module as well.

I'm obviously wary of removing a user without using the Zentyal UI. How can I safely remove / fix a system user without breaking LDAP synchronisation? Thanks!

Hi All,

I'm having real trouble with Samba Share Authentication, something broke it recently & I'm trying to work out what changed to cause it to break and how to fix the live server...

The server is configured as a PDC/file server (2.2 install, upgraded to core version 2.2.3) and until recently the samba shares were all behaving themselves according to the ACLs I had set for each with Zentyal User Groups. Most shares were restricted to some of the user groups (up to 4 groups per share), and one shared folder was accessible to all (i.e. adding all available user groups to the ACL). No 'guest' enabled shared were created.

After the server has been up for almost a month (and untouched for over a week) I have been contacted by users who are unable to access the network shares they were previously able to. The folder opens & contents are displayed, but accessing any of the files results in "Access denied". This is consistent with XP, and Win 7.

Logging in to the web GUI failed with the same message I have previously discussed.

Code: [Select]
Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

As before I deleted as much as I could (deleting logs didn't help, but deleting the backups did free enough space) and was then able to log in to the GUI.

I changed one share to allow guest access, but windows users were still unable to open the files from this guest share. With panic rising steadily I then created a test folder, enabled guest access to it but users were unable to read or write to this either until I chmod'd the folder;

Code: [Select]
sudo chmod -R ugo+rwx /testfolder

only then was a user able to read objects or write to this test folder. Data was then copied into this now unprotected folder so that users could at least access a copy of the data, while this problem is being resolved.

I have tried accessing the samba shares on the server directly using smbclient, with a user that has admin access to the share in question;

Code: [Select]
smbclient -U <Username> //<IP Address>/<Share>
Enter <Username>'s password:
Domain=[Correct Domain Name] OS=[Unix] Server=[Samba 3.4.9]
smb: \>

ls -al successfully listed the contents of the share, however trying to get a file resulted in access denied.

Code: [Select]
smb: \> get "Filename.docx"
NT_STATUS_ACCESS_DENIED opening remote file \Filename.docx

Suggestions are welcome where I go from here.. Thanks!

I cannot log in to my x64 Zentyal 2.2 machine;

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Installation and Upgrades / [SOLVED] LDAP Resync
« on: October 19, 2011, 09:48:18 am »
Hi,

I'm running Zentyal 2.2 (64 bit) on a recently commissioned server, recently slapd has started using a great deal of processor time and I'm getting many LDAP related messages in the syslog every second;

Code: [Select]
Oct 19 08:33:33 servername slapd[10605]: last message repeated 4 times
Oct 19 08:33:33 servername slapd[10605]: connection_read(28): no connection!
Oct 19 08:33:33 servername slapd[10605]: connection_read(28): no connection!

Oct 19 08:33:33 servername slapd[10605]: last message repeated 4 times
Oct 19 08:33:33 servername slapd[10605]: connection_read(28): no connection!
Oct 19 08:33:33 servername slapd[10605]: last message repeated 5 times
Oct 19 08:33:33 servername slapd[10605]: <= bdb_equality_candidates: (displayName) not indexed

After reading around it seems need to re-index the LDAP database http://trac.zentyal.org/wiki/Documentation/Community/HowTo/LDAPoptimization however when I try, none of the commands are recognised;

Code: [Select]
root@servername:/usr/share# sudo stop ebox.slapd-frontend
stop: Unknown instance:

which isn't really surprising as there is no slapd-frontend on the machine (there is the config file though /etc/init/ebox.slapd-frontend.conf ). If I try stopping/starting slapd directly;

Code: [Select]
root@servername:/usr/share# /etc/init.d/slapd stop
Stopping OpenLDAP: slapd.
root@servername:/usr/share# /etc/init.d/slapd start
Not starting slapd: SLAPD_NO_START set in /etc/default/slapd

yet slapd is still running despite having stopped it..

Code: [Select]
openldap 18591 11.0  0.2 370172  9244 ?        Ssl  08:41   0:08 /usr/sbin/slapd -d 0 -h ldap://0.0.0.0/ ldapi://%2fvar%2frun%2fslapd%2fldapi/????x-mod=0777 -u openldap -g openldap -F /etc/ldap/slapd.d/

How can I resolve the problems slapd is having ?! Thanks!
