Hi FOGers!!

We have some strange issues when we upload images to the server and we don´t have find the reason of this behaivour.

The issue appears when the server try to move the image from /images/dev/abcdefg12345 directory to the destiny, the FTP can´t move the file or the directory and the destiny directory appears empty.

In the vsftpd log appears the error:

The permissions in /images is:

drwxrwxrwx  295 fogproject apache 16384 nov  3 09:40 images

We have migrated the old server, fog 1.5.5, to the last one, fog 1.5.10, we made a fresh install but we migrated the storage from the old one to the new one. Then in /images we have a mix of owners XD:

drwxrwxrwx    2 root       root     280 ago 24 10:27 aula-vc-filologia-aulavhm2-alumno3450

drwxrwxrwx    2 fogproject apache   226 abr 29  2021 aula-vc-filologia-aulavht1-roomserver

The question is easy Who is the owner of images directories?

@orborneee When I installed the new server on May, I had problems with the LDAP autentication. I don´t know if your problem is the same but you can test if works.
Edit the /var/www/html/fog/lib/plugins/ldap/class/ldap.class.php file and comment the line 235:

//@$this->unbind();

Hi @Sebastian-Roth,
Yes, I think that the dev-branch solves the problem. I tried to install from master branch and the problem with the xinetd appeared, but with the dev-branch apparently works fine

@Sebastian-Roth Hi Sebastian!
I will try the dev-branch, the new server is the develop server. If the new release version has PHP 8 support then great
The problem with the xinetd is more “special”, only affect to RHEL 9 and higher.

Workaround: Install php 7.4 in RHEL 9
Install PHP 7.4 (https://www.linuxcapable.com/how-to-install-php-on-centos-stream/)

# dnf upgrade –refresh
# dnf config-manager --set-enabled crb
# dnf install \
    https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm \
    https://dl.fedoraproject.org/pub/epel/epel-next-release-latest-9.noarch.rpm
# dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-9.rpm -y
# dnf module list php
# dnf module enable php:remi-7.4 –y
# dnf install php php-cli php-common php-fpm php-gd php-json php-ldap php-mbstring php-mysqlnd php-process –y

Hi again! I am back
I am installing a new server under RHEL 9, but I am having problems with the install process.

Two big problems:

• PHP version 8: the implode function is deprecated and have changed (https://www.php.net/manual/en/function.implode.php)

 implode(string $separator, array $array): string

Alternative signature (not supported with named arguments):
implode(array $array): string

Legacy signature (deprecated as of PHP 7.4.0, removed as of PHP 8.0.0):
implode(array $array, string $separator): string

Join array elements with a separator string. 

The order of the parameters is different. This affects to all calls of the implode function.

*xinetd package is not available in RHEL 9
From https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/pdf/considerations_in_adopting_rhel_9/red_hat_enterprise_linux-9-considerations_in_adopting_rhel_9-en-us.pdf

The xinetd package is not available in RHEL
9. Its functionality is now provided by
systemd.

@sebastian-roth Yes, I saw it. I am following it XD
it can be the way to do it.

The problem are the dual images: windows + ubuntu or syspreped windows + ubuntu. And other type images too (multidisk, …)

@sebastian-roth I would like to customize the boot sequence , if is possible from the web UI and not custimize a script in the server.

Hi @Sebastian-Roth ,
Then is not any global solution I need to devise one.

Hi,
Any advance about NVRAM and EFI or how update his variables when you deploy an image?
I read the thread FOG does not copy NVRAM/EFI Bootorder but is two years old.

I need to update the boot order when I deploy dual images (windows and linux) with syspreped windows partitions.

Cheers

Hi @Sebastian-Roth,

Now works fine the FOG client

Thanks for your fast reply

Hi,
I am trying to install the FOG client under Kubuntu 20.04 but something goes wrong when the daemon initiates. I follow the instructions of the wiki to install it.

Any ideas?

You can see some information about it in this thread:

https://forums.fogproject.org/topic/11402/how-to-use-accesscontrol-plugin

Be careful if you implement a great number of rules, the behaviuor can be unstable.

You can only increase the debug log using checkpoints. You can use the error_log PHP function to debug the outputs.

https://www.php.net/manual/en/function.error-log.php

Please check if you have free space in /var.
I had this problem sometimes in the past.

@iteixido I will fix it as soon as possible

@iteixido I will fix it as soon as possible

Thanks @iteixido ! We will fix the bug as soon as possible

Hi @gn_ro ,

I tested it in the last version 1.5.8 and works fine.

Take note that you must have opened the 445 TCP port in the client and you only see the status in the host page, not in the search page.
