The problem was the client version. (old version: 0.9.12)
I had to install the new one on each computer (0.11.9), then reboot each computer.
Then “reset encrypted data” on the group
Now it works fine.
I thought that once there was a new version on the server the client updated “alone”.

@wayne-workman i used " your packages line" and it seems to work.
Then now i have to test pxe boot, capture and deploy !!

THanks for your help

Hello,
in first thank a lot for your answer.
For my test i’m going to work with a virtual machine with only one interface, then forget the “3 networks”
I begin by installing fog like that :
(i use my own dhcp server)

Type d’installation : N
IP du serveur FOG : 192.168.39.243
Would you like to setup a router address for the DHCP server? : n
Would you like to setup a DNS address for the DHCP server and client boot image? : n
Would you like to change the default network interface from eth0? : n
Would you like to use the FOG server for DHCP service? n
This version of FOG has internationalization support, would you like to install the additional language packs? n

My own dhcp server is configured like that (it has 192.168.39.247 for ip address):
subnet 192.168.39.0 netmask 255.255.255.0 {
range 192.168.39.40 192.168.39.230;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.39.255;
option routers 192.168.39.254;
next-server 192.168.39.247;
filename “pxelinux.0”;
}
then next server is the dhcp server itself

Here is a part of the PXE configuration (on my own dhcp server. (The dhcp server act as dhcp, tftp and pxe server)

My question is how i could add entry for fog server using ipxe while i’m iusing pxe (pxelinux.0)
Thanks again for your help

Hello, i think i’ve got the same problem except i made modification on the web interface :
i didnt want the “images” directory be at the root (/images)
then i copy the images directory into /home/images.

Then i modify the image path on the web interface, i thought it would modify the export file also but it seems not.

then i had to modify manualy the export file. Now it works fine.
Could it be the problem ?

@need2 now i agree with you : if you accept that mysql root has no password
and if you know that if installer told you to go to http://192.168.39.243/fog it means you have to go to http://192.168.39.243/html/fog.
I know it’s a ridiculous bug of the default installer (without parameters) but it disturbed me

any way fog seems to be a great program, the forum is very reactif and it permit me to go on
Then thanks again for your help i appreciate
sorry for my poor english
@Tom Elliot : i will try with --docroot to tell you if it works.
But can you confirm me that the installer without parameters make a mistake between http://192.168.39.243/fog and http://192.168.39.243/html/fog to be sur we are agree ?

Thanks again for your help everybody !!

@plegrand said:

It’s not our dns servers

You don’t have to use them. You can make your own and direct all hosts to use yours.

I install dynamique DNS with bind and it works fine. Thanks again

@Wayne-Workman
I just made the test unicast (deploy and not multicast)
It’s a room with 12 stations.
2 stations failed
10 works fine (1.6 GB/min)
i’ll tell you more tomorrow

@Jbob Hello
In first sorry for this long delay
I just made the test today with the latest client. Everything seems to work fine !!

@Sebastian-Roth May be i could give you access to this machine if it’s usefull ?

Boot PXE OK
Capture OK
Deploy OK

@george1421
It seems yes

@plegrand
Everything seems work fine and i’ve no more error in log files.

@george1421

I had to modify this file :
/etc/php/7.3/fpm/pool.d/www.conf

Now it seems to work.

@george1421
Then i made some tests

Multicast session (test) with 2 target computers : about 1.7GB/min rate

Multicast session (test) with 3 target computers : about 1.7GB/min rate

Multicast session (test) with 4 target computers
The 2 first target computers didn’t start i cant understand why.
then i removed these to computers from the session (test)
i create a new multicast session (test2) for these 2 computers

Then there is 2 sessions running (test and test2) and all the target computers have about 1.15GB/min rate

All the computers have 2 partitions and strangely the first partition is slower than the second : about 700MB/min rate

@george1421 said in Multicast very slow:

Under a multicast you should get just slightly less than unicast speeds.

So what’s the multicast interest if it’s not faster, apart from not flooding the network?

I’m going to make some tests this morning with 2, 3, 4 target computers.
I will tell you the result

@george1421
The 6450 has all his ports 10/100/1000
not the 6250 only the uplink ports are on 1000

@george1421 said in Multicast very slow:

Do you have the capabilities to run a second network wire from the switch where the fog server is to the switch where the target computers are? (I’ll explain more if you can).

It’s quiet already the case
The switch (OS6250) where are connected all my target computers is just below the switch where the fog server is (OS6450).
And directly connected by a 1GB link
Then, only target computers are on a 100MB link
