@marcolefo Sounds like the package ‘build-essential’ should be an install target of the FOG install script? It doesn’t seem to be.

However I think my distro installs of Debian 12 and Mint 22.1 both installed that package by default.

Solved for me on Linux Mint 22.1

The base problem is that php-mysqlnd is a “virtual package” that is included in the package php-mysql, and trying to install it individually (as the FOG install script does) fails with apt dumping a list of php mysql versions and that “You should explicitly select one to install.” Even if php-mysql is already installed.

The solution for me was to remove php-mysqlnd as an install target in the FOG install scripts. As of this date, that includes:

In file [fog install pkg path]/lib/ubuntu/config.sh:

remove ‘php-mysqlnd’ from line 26 "packages="apache2[…]

In the file [fog install pkg path]/lib/common/functions.sh:

remove the lines

php-mysql*) for phpmysql in $(echo php-mysqlnd php-mysql); do eval $packagelist "$phpmysql" >>$error_log 2>&1 if [[ $? -eq 0 ]]; then x=$phpmysql break fi done ;;

@adam1972 FYI, there are no pending tasks… I just tried creatinga snapin bash that uninstalls the client, to see if it would stop repeatedly rebooting… It just sits there. The log has a “a power operation is pending, aborting module”… I can’t find anything that’s is pending… especially after rebooting several times lol

Edit: So, the target PC was not identical after all. It had an optical drive as well. Don’t know why that would change anything. From dracut emergency shell I found that the driver for the SAS controller card (aacraid) was not loaded for some reason. Works fine on other target PCs without the optical drive…

@RocksAndRolls I’m not sure how much additional help I can provide here but where it failing is at the end of the imaging process, the target system logs into the ftp server on the FOG server using the fogproject user account. That fogproject user MUST be able to rename the captured file in /images/dev from the mac address and the move the directory from /images/dev/<mac_address> to /images/<image_name>.

If you have verified you can log into the fog server via ftp as the fogproject user using the password saved in the fog ui then it has to be a permission issue on the /images directory.

The image capture process is

FOS Engine -> connects to /images/dev NFS share and creates a directory that matches it’s mac address
FOS Engine -> Uploads the disk connect as the root user (on the FOS Engine)
FOS Engine -> Connects to the FOG server as fogproject user and issues a mv command to move the directory from /images/dev/<mac_address> to /images/<image_name>
FOS Engine -> Logs out of ftp and completes the cleanup before reboot.

@COE Typically if the permissions on the /images directory get messed up you can reinstall FOG and it will fix the permissions.

If you run the chmod 777 /images that will make the directory world writable but not the existing files / folders under that directory. If you use chmod -R 777 /images it will change everything under that directory to world writable.

But before you do that, the linux user fogproject should have read write access to /images. The password for that user is found in the hidden file /opt/fog/.fogsettings That is the user account fog uses to move files around while imaging.

OMG !!!
i’ve been walking past it since the beginning without seeing it!!! too newbiees

Thank youu @)

@Tom-Elliott Success. I switched to single-user with init 1, and installing systemd-sysv worked fine.

As this is a machine upgraded from debian 11, maybe it wasn’t using systemd. Installation of 1.6 worked no problem Thanks,

@AUTH-IT-Center That is correct. That’s what that FOG Settings item is meant to do. If that is checked, on registration it should set that flag on future registrations, but it doesn’t on existing hosts that were registered before it was checked. If after this is checked and a new host registers and this isn’t working, I would believe there to be a bug.

Though a workaround exists, so while, it would be a bug, it may not be the biggest concern to get fixed immediately over say actual imaging issues.

@PatrickL You might want to review this post: https://forums.fogproject.org/topic/17648/massive-cpu-usage-from-a-service

That .sysvd is suspicious and very similar to the thread above.

@adam1972 The AD setting isn’t general. Basically it’s enforcing the reboot happens to change the hostname and/or complete joining the domain.

I think since there’s multiple points of hostname changing this isn’t working correctly (obviously) as the hostname shouldn’t need more than maybe 1 or 2 times to change it. Snapins running still is the end of the problem though? Not sure how to approach. Since hostname change is expecting to reboot maybe this is preventing the snapins from running. We could test that by disabling the hostname changing option altogether on this host?

@LLamaPie Everything has been clean now for about a week. I would consider this at least resolved on our end. Still no answer about when it became compromised exactly. Our hyper-paranoid theory is it may have been a “time bomb”. This could have been on the server for months before popping up. Our long-term solution is keeping endpoint protection in place. I have nothing else to add but if I discover anything I will let everyone know.

@45lightrain ok so lets start with some basics.

a 1GbE link (under theoretical conditions) is 1 Giga bits per second or 128MB/sec or 7.5GB/min raw data. Understand that there is ethernet overhead and you will never achieve 7.5GB/min.

So how is it possible to see speeds above 7.5GB/min on a 1GbE link? Simply data compression. So what you are seeing in the part clone screen is a composite speed including fog server speed sending the data to the network, network transfer time, the client receiving the image, expanding in it memory, and then writing it to disk.

If you are getting 5.5-6.1GB/min in partclone on a pure 1GbE network your fog environment is well designed and network well managed.

I wrote an article a few years ago that has some benchmark tools you can use to see where you can get additional speed out of your setup. https://forums.fogproject.org/topic/10459/can-you-make-fog-imaging-go-fast

So the executive summary is that if you want to go fast.

Install at least (1) 10GbE network link. (If you have many computers running the fog clients, run (2) 10GbE links in lag configuration. If you have many clients hitting your fog server while you are trying to image use a ssd disk or nvme drives on your fog server (I would look at spending here the last, typically its not the disk that is slow, unless you have just a single spindle hdd driving your fog server). Try to get the 10GbE network as close to the target computers as you can. If you are trying to image multiple target computers at the same time look into fog casting your image to the target computers. When capturing your image use the zstd compression tool over gzip. Set zstd at compression 11 to start. If your target computers have a lot of horsepower, 16GB of ram, and fast nvme disks you can get more data through your network by compressing the data more. This will put a heavier load on the target computer expanding the image and writing it to disk.

Think if your imaging as 3 factor triangle. You have server speed to get the image to the network adapter, the speed at which your network can move the image to the target computer, and finally the time it takes for the target computer to intake the image, expand it in memory and write to disk. In the imaging process the fog server typically has the least impact on imaging of the three.

@JJ-Fullmer Good to know, thank you so much 😎💯
