Installation and Upgrades / Re: /boot partition full

« on: June 06, 2013, 09:45:22 pm »

Then still the question: why such a small partition. Only 280MB.... 

*grin* - for me this looks oversized, probably because I am getting old . My current Ubuntu workstation has three Kernels installed. All three together do occupy 79 MB. So why should one want to waste more space for a dedicated /boot-Partition? (If you have a reason to have one in the first place.) 

Being off-topic here I hope my hint regarding "dpkg" helps Labomba...

I suppose as a warning when running

Code: [Select]

sudo apt-get purge linux-image-x.x.x-x-server
If you can help with this, you're very welcome 

When apt-get fails removing packages I fall back do dpkg: sudo dpkg -P  linux-image-x.x.x-x-server

This looks like a manual install with softraid (mdadm)
But still I am puzzled why /boot is chosen on a separate disk and why so small?

As a sidenote: I've set up several systems with LVM2 on a Raid1/Mirror. It is not very long ago that Grub2/Grub/Lilo was not able to boot from a logical volume. The usual workaround was to prepare a small /boot Partition either standalone or a small, second Raid1for this purpose...

die Ein- & Ausgaben sind ich gemacht...

Okay. Leider kann ich aus Grafiken heraus nicht zitieren - den Text zu posten hätte genügt  (Ja, man kann copy-n-paste auch in/aus dem cmd.exe-Fenster machen: schau bei Gelegenheit mal in das Fenstermenu, links oben im Fensterrahmen, da ist ein "Bearbeiten"-Menü.)

Die Screenshots bestätigen, dass 10.0.2.1 dein Gateway ist - bzw. sein soll. Weiter oben hatte ich schon einmal nach 10.0.2.1 gefragt.

Falls der Traffic durch Zentyal hindurch geroutet werden soll und Zentyal 10.0.2.65 ist, dann ist das doch schlicht falsch!

Entweder gibst du der Zentyal-Box die Adresse 10.0.2.1 oder sorgst für Gateway=10.0.2.65.

Hi. Just wanted to thank you for this! It has been fantastically useful.

Thanks for the flowers 

<volume user="*" fstype="cifs" server="192.168.0.4" path="%(DOMAIN_USER)" mountpoint="/home/%(DOMAIN_USER)" options="sec=ntlm,nodev,nosuid" />
<volume user="*" fstype="cifs" server="192.168.0.4" path="temp" mountpoint="/home/%(DOMAIN_USER)/SRV/temp" options="sec=ntlm,nodev,nosuid" />

It seems it wont work without this temp mount.

That's really strange, thanks for documenting it here. From time to time one finds a specific situation where an otherwise well working configuration simply does not do it For me this seems to be part of the price I have to pay living in free GNU userland.

Best regards

jep, 10.0.2.65 soll meine Zentyal-Box sein! .... daran was falsch? (private IP, eben) ein ping von den Cliens an 10.0.2.65 funktioniert.

Daran ist natürlich nichts falsch. SOFERN die Clients das auch wissen! Falls die von "Gateway   10.0.2.1" ausgehen, laufen die Pakete ins Nirgendwo.

Ich hatte drei Windows-Befehle erwähnt. Warum postest du nicht deren vollständige Ausgabe? Bitte inklusive deiner Eingabe!

Remember that if you reset the file-sharing module all the acl will be rewrited using your current Zentyal File-Sharing module configuration.

This makes me ask a question: what does "reset" mean in this context?

• Will it re-assign Zentyals knowledge of acl on restarting the File Sharing module?
• Will it re-assign Zentyals knowledge of acl on disable/re-enable the File Sharing module?
• Will it re-assign Zentyals knowledge of acl on rebooting the server?

Best regards

Hi,

Herzlich willkommen!

   DHCP   eth0   external   IP   192.168.1.44      
      statisch      Netmask   255.255.255.0      
                     
      eth1   internal   IP   10.0.2.65      
      statisch      Netmask   255.255.255.0      
            Gateway   10.0.2.1      
            Server01   10.0.2.65      

Mag sein dass ich das falsche interpretiere: die Zentyal-Box ist 10.0.2.65. Korrekt?

Was ist denn 10.0.2.1? Das wird als Gateway an die Clients gemeldet.

Nutze als Gateway für die Clients genau die Adresse, die die Zentyal "innen" hat - .2.65. (Sofern Zentyal als Router genutzt werden soll.)

Mach dann auf einem Windows-PC eine Kommandozeile auf ( WIN-R "cmd.exe", <Enter>) und spiele mit den Befehlen "route print", "ipconfig /all" und "traceroute 8.8.8.8". Die Befehle liefern via "/help" (also "ipconfig /help") etwas Hilfe...
 
Viel Erfolg!

How to fix/set proper permissions (ACL) on files copied to a samba share via SSH ?

Please do the following: create a testshare from GUI (or use an already existing one). Set some rights for your groups/users. Go to a shell prompt and cd directly into that directory. Enter one command:

Code: [Select]

getfacl .
Read "man getfacl" etc. for details.

Installation and Upgrades / Re: HOWTO: Ubuntu client with LDAP authentication and pam_mount for mounting $HOME

« on: April 19, 2013, 07:47:53 pm »

Thanks for How to.

Is's a pleasure for me 
 

my \etc\ldap.conf in ubuntu client is:

If i test a user with ldapsearch command, show me a error:

Please check if you did this:

Code: [Select]

~# ln -s /etc/ldap.conf  /etc/ldap/ldap.conf

For the ldap-utils package (which contains/supplies ldapsearch) the relevant file is /etc/ldap/ldap.conf!

Try adding "-v" to ldapsearch to get a verbose output.

Does anyone know how to use skel with this setup?

What do you mean?

"/etc/skel"-content as template for new users does work as expected. At least on my machine. Verified a second ago - just for you

Installation and Upgrades / Re: iptables 239.0.0.0 gets replaced by 224.0.0.0 - Zentyal 3

« on: February 26, 2013, 10:26:58 am »

sudo iptables --append OUTPUT -s 224.0.0.0/4 -d 192.168.17.0/24 -j ACCEPT

sudo iptables --append OUTPUT -d 239.0.0.0/4 -s 192.168.17.0/24 -j ACCEPT

I get no errors, which seems to be good, but executing "iptables -S | grep 239" gives me an empty result.

The second pair is redundant. 239/4 is included in 224/4:

Code: [Select]

~$ ipcalc 224.0.0.0/4

Just to show what I mean: you get the same output for a query with 239:

Installation and Upgrades / Re: Samba large file problems

« on: February 22, 2013, 09:45:08 am »

Some of the settings may differ from your setup than mine
1. The files are avi, mkv or mpg.
2 the ACL list on the shares is set with Administrator level and Read Write. (no guest access enabled)

Try to open the files (not copy) from samba shares from within Linux (Mint 14 64bit) and Win 7 64 bit and see if you can playback the file.
See if you can open mkv files of 4.7Gb or 8Gb...

Okay, I did a second test with my Zentyal box and a coincidentally available fresh Windows 7 client, 32bit, not being a Zentyal/AD member. On the server I have an old .avi with a size above 8 GB. My shares have no guest access allowed. My testuser has only read access.

The Win7 sees the file and clicking it starts the default Mediaplayer. Replay starts immediately. Fast-Forward dragging the position-slider works without any noticeable delay (actually I'm a little bit surprised about this one).   

I also copied that file from Zentyal to Windows and back. No problem.

The files were put to the server from the linux machine... so maybe it has something to do with permission to execute the file since the transfer succeded...

A simple read access permission should be sufficient, shouldn't it? Windows doesn't "see" the executable bit.

For a Linux client: I never did something like double-click on an "executable" avi in a graphical file manager. Do you do this? Can you "File - Open" that file from within a Mediaplayer? (Actually I usually do watch videos from command line with something like "vlc myfile.avi".)

Another idea regarding windows: do you have a Virus scanner which is keen to scan the whole file before letting a client application open it? My Windows 7 is a test machine without a license, not activated, no Antivirus installed -- and doomed to get deleted next week 

The same idea is valid for the Zentyal server: did you enable Virus file scanning "on demand"? Might be very slow for very large files...

Best regards

So the problem must be in SAMBA....

I've just tried to recreate that problem. On my Zentyal box I did:

1) create 2.4 GB of random data: # dd bs=65536 count=40000 if=/dev/urandom of=2.4gb.urandom
2) create a hash # md5sum 2.4gb.urandom > 2.4gb.urandom.md5

On an Ubuntu 12.04 box as a cifs client I did
3) fetch file from 1): $ cp ~/SRV/temp/2.4gb.urandom* .
4) verify md5sum on client
5) copy this large file back to the server: /tmp$ cp ./2.4gb.urandom  ~/SRV/temp/2.4gb.urandom.copyiedback
6) verify the copied back file

All copy processes succeeded fine.

Notes: this is not ext2/3/4 but ZFS on the Server. Wiring with Gigabit Ethernet. All software updated except Kernel 3.2.0-37 instead of -38 on server. Server with 64bit OS, client with 32bit.

Sorry, this won't help you...

Installation and Upgrades / Re: Zentyal 3.0 / 2.2 Samba slow / poor performance transfer speed of small files

« on: February 18, 2013, 10:20:30 pm »

zentyal 2.xx (i don't remember minor version)  - transfer speed about 150KB/s (OK)
zentyal 3.0.12 - transfer speed about 30-40KB/s

I have no helping hints for you though your (low) transmission rates are extreme. If you look around you might find some similar unsatisfying discussions, for example here:   http://forum.zentyal.org/index.php/topic,14047.0.html where I confirm the type of your problem with my own values.
