 |
|
Hi there!
What I did:
- I am using the newest m23 server in a virtual mashine
- I integrated some existing clients this way: first in the web-app, after that with the line for ubuntu mashines written in the handbook
- integration worked fine (I think)
- later I don't see the right Ip in the client control center. It shows 127.0.0.1 at any client
- I can cange the IP via the "changing client"-Option, but the information is lost sooner or later (both ways (database and server-option fail)
- I had one client successfully changed, installed some programms, after that the Ip is gone again.
- now I can't install anything on clients via m23
What did I do wrong?
Thanks! |

Hi,
I'm currently very busy with organising the "Kieler Open Source und Linux Tage", but at the beginnig of the next week I should have time for analysing your problem.

Are you using m23 15.2?

Do you mean that you provided username and password?
| matz wrote: | | later I don't see the right Ip in the client control center. It shows 127.0.0.1 at any client |
What IP did the client have before? How did you configure the IP?

When is it lost?

If the client has no IP, m23 cannot change the IP on the client, because the commands to change the are executed over the network. So it sounds more likely that there is an DHCP server, that gives out wrong IP settings.
What version of Linux Mint 17 (17, 17.1, 17.2) with what desktop (Mate, Xfce, ...) do you use?
Could you install Linux Mint in VirtualBox (the same way, you did with the other Linux Mint clients), export and upload it for me? If this is prossible, please give me the link where I could download it.

Yes.

I did this. First client name, Ip, username, passwd. It tells me than: integration successfull. (But nothing happens)
I than start the manual process on the client with cd /tmp; wget http:...
But this stops on a certain point (~37% of integration process) with the message: ./work.php-"longnumber": line 2: CLIENT_getClientName: : command not found
I deleted the client and did it again. The process starts over at 37% but again stops at about 50%.
each time the ip of the client gets lost.

What IP did the client have before? How did you configure the IP? |
for example: 192.168.23.211. I did it like described above.

I don't see it anymore, after clicking on client overview - theclient - controlcenter. This happens after the error occurs on the client.

Well I had this problem before, but now the dhcp-server is switched off. m23 doesn't complain about that anymore.

to make the automatical integration work, you need to install the SSH daemon (as described on the page you linked  ).
| Anonymous wrote: | | But this stops on a certain point (~37% of integration process) with the message: ./work.php-"longnumber": line 2: CLIENT_getClientName: : command not found |
I cannot reproduce it here. I've just sucessfully integrated a Kubuntu 14.04 (same basis system as LM 17.2). SSH daemon was installed.
Please post the contents of the work.php-... file where the error occurrs.
How (NetworkManager? via /etc/network/interfaces?) did you configure the IP of the client? Is the IP a static IP or dynamically fetched from a DHCP server?

Hi,
I've tried the integration with Linux Mint 17.2 Xfce amd64 and it worked.
I did the following steps:
- Started LM 17.2 via ISO in VirtualBox
- Changed network settings in the network dialog to static IP
- Installed on (virtual) harddisk
- Rebooed
- Installed SSH daemon
- Integrated the VM via m23 webinterface (with username/password of the user that was created during setup)

Hi,
thank's a lot for your replys! I can't concentrate on this issue so much at the moment. But I hopefully will the next days.

I did the same in my first attempts (I guess).
About 1): in my case LM 17.2 is the host for the VM (which ist m23). Do you mean that?
About 2): Do you mean in /etc/network/interfaces? Btw I was not quite sure about the right setting for "network". I used the same as for the gateway (192.168.23.1). The server has 192.168.23.23, the LM 17.2 has the static IP 192.168.23.10.
About 3): I just whatched your video again an noticed that you chose some other options as I did (I always chose the default settings)
About 5): I did that on the clients.
About 6): I chose username and pw of the client-admins.
As mentioned before, it first seemed to work fine, so I integrated lots of clients... Later I found out, they didn't cooperate as I whished.  I deleted them in m23-server, but how can I delete all m23 installation on those clients? |

no, I meant that I installed the client (to integrate) into VirtualBox. I created a new LM 17.2 VM for the assimilisation test.

This looks ok. If you run the client in VirtualBox, you need to use "bridged networking".

On VirtualBox?

With
| Code: | find /etc/rc* | grep m23 | xargs -n1 rm
find /etc/init.d/ | grep m23 | xargs -n1 rm
sed -i 's#^Acquire#//Acquire#g' /etc/apt/apt.conf.d/70debconf |
executed on the m23 clients, you can remove the start of the m23 initscripts and the APT proxy settings for caching the packages on the m23 server.

Yes, this one: http://m23.goos-habermann.de:2323/video/m23-Server_in_10_Minuten.ogv
The client doesn't seem to get the IP properly. I'm unsure how to start the integration. The client needs an IP for that. So I give it the adress manually for the integration process and switch back to dhcp later?
This works out till a certain point. At about 37% the process stops. The connecrion is lost than. If I reboot the client it does not get an IP from m23.
Somehow the client X-server doesn't work properly than (cinnamon in save mode). This can only fixed by deleting all m23 informaion on the client as you described above.
I'm installin a lm17 installation in VB at the moment and will give you the link later.
Thanks!

I integrated a virtual LM17.2 client successfully. The only difference in the setup was: I used the 32bit version inspite of the 64 bit I use on the real mashines. (And I didn't even switch off the htcp in my router this time.)
result:
I could (almost-see below) update the client via m23.
Nice, but my problem with the real mashines persists. 
Btw:
Is it possible to answer configuration-questions that I see in the clients monitor-window during update?
If I try installing packages, the server keeps on forgetting the sources settings.
and
I can't find any packages through the "install"-dialog. It's only possible via "Edit package selections"
a bug or a feature? |

Hi,
you make me a bit confused
| matz wrote: | | The client doesn't seem to get the IP properly. I'm unsure how to start the integration. The client needs an IP for that. So I give it the adress manually for the integration process and switch back to dhcp later? |
If I read it correctly, the client has no static IP address, but there is a DHCP server that distributes IP addresses. Switching off the DHCP server while integration will make it even worse.
A static IP adress is only given, if a fixed IP address is configured on the client without any DHCP server involved. A real static IP address is configured via the network icon (bottom right) on the desktop like in this screenshot.
So please check the network settings of your client and make sure that it uses a static IP address.
OR
If you want to use your DHCP server, make sure it gives out the same IP address to the same client every time. This could be configured on the DHCP server by "binding" the client's MAC address to the IP address the DHCP server will give the specific client.

I don't think, that this is caused by the architecture of the distribution. In my tests 32 and 64 bit versions both worked.

Do you update the clients via the m23 webinterface?

This should be caused by the IP problem too.
During the assimilisation process the sources list of the client is transferred to the m23 server and selected for the client.

Hi, sorry for that!  I think I have tried so much inbetween, that my writings are a bit confusing.
I have tried both ways you described several times since i am trying to find a way through this.
Mabe I found something intresting today.
I gave the client an static IP.
Integration worked fine till 37,5%
Than it stopped. The Ip was not known in the control center anymore
I recognized now, that it was written the wrong MAC Adress there. I'm trying to integrate clients via wlan. But the control center shows the lan-MAC adress.
Could this be the problem? I have no cable at the moment to try the other way.

I tried it via LAN-cable now and it worked out perfectly!
So, is it (MAC vs wlan) a bug or an unsupported feature? Maybe I just didn't read carefully enough?!

This problem stays the same. The search option in the clients "install"-dialog doesn't find packages that are in the clients distribution-sources. I can only search them in "Edit package selections", and save as "package selection". After that I can install them via the "groups overview"-Dialog. Is it supposed to be like that?
(Maybe this should be an extra post...)
Btw: Thanks so much for your support!!! |

Hi,

this is great 
The installation and assimilastion routines were not designed to work over WLAN
I will think about adjustments for the routines or the manual...
| matz wrote: | | So, is it (MAC vs wlan) a bug or an unsupported feature? Maybe I just didn't read carefully enough?! |
During integration the MAC of the first wired network card (eth0) is written to the m23 database on the m23 server. The MAC is used for network booting only, so it is not a big deal, if it is not the MAC from the used network card of an assimilated client. Network booting is used for debugging and installation of operating systems only. Addimilated clients cannot be re-installed via m23.

No, this is strange, because the "Install packages" and "Edit package selections" dialogs are actually the same page called with different paramters.
Building the package index for searching the packages in the m23 webinterface keeps some time. Maybe the index was not build when you used the "Install packages" page, but later when using "Edit package selections".
Do you have under Packages -> "Package sources" an entry staring with "From_"?
Does it match the sources.list of the client you integrated?

I don't think so.

Yes I have. Those clients that are integrated are choosable. Should one of the clients or the distribution be chosen here? |
