Hi All,
My boss and I have been mulling around an idea to put on a presentation on FOG at a conference in Ohio called Brainstorm k20 next year.

I think it would be beneficial especially for the k12 conference goers. Us k12 folks are always short on the budget and we look for products that just work. I believe FOG fits both categories since it is open-source, free, has great support on the forums, and you don’t need a degree in Microsoft Deployment or SCCM to use it.
We are thinking of going over the basics and offering a VM Template to the audience for them to spin up a VM and provide instructions on how to change the IP/set up the DHCP options/configure their networks for FOG.

I wanted to run it by you guys to see if you have any tips or things you think I should go over? This is still in the very early stages of planning as it will take place possibly in May of 2020.

If anyone has input, I’d greatly appreciate it. I want to spread the good word of FOG to my cohorts but also do it right!

Thanks!

@Wayne-Workman said in New FOG Testing dashboard. Feedback?:

I’ve shut down the old tests, and switched the new tests to use fogtesting.theworkmans.us

Well done man! I’m going to miss the successful patch streaks just because that was fun to look at. I understand why its gone though. I am probably due for an update to 1.5.5 from 1.5.4 and this is a great resource.

I wanted to stop by and say that I can concur that I was able to image the 2018 newest x1 carbon using the Lenovo Dock as well. I did not try any other means as we purchased the docks with the carbons and that seemed to be the logical choice. I apologize to @AsGF2MX for not saying this earlier to save you some hassle. Just didn’t click in my head that I recently imaged these with this method. Best of luck in your future Fogging.

@george1421 If you can locate the thread that Tom gave these instructions and/or a wiki article on how to do it, I am more than willing to try. I appreciate your time on this.

@george1421 I did indeed reboot and didn’t see any difference. On a gut feeling, I doubled the checkin time from 180s to 360s and that has marginally helped the CPU usage. I am just puzzled why this wasn’t an issue at the end of the last school year? Our number of clients has not changed and I have been on 1.5.4 for a while now. Here is the graph of my current CPU Usage on that VM. You can see where it was at, when I made the setting change in www.conf, changing the checkin time, etc:

I did notice I still had many php-fpm processes, but overall utilization seems to be down:

EDIT: I did forget to mention I have this running on 2vcpus and 8GB of Memory. Do I not have it specced high enough?

Hi George,
Most of these settings were set properly. Below are the ones I set:

pm.max_children = 35
php_admin_value[memory_limit] = 256M

A reboot after that still yields 100% usage and way too many php-fpm processes.
I have about 1300 devices using the FOG client. I realize this is a lot, so I did set the checkin time to 180s. Do you think increasing that more would help?

Thanks!

Hello All,
I came in this morning to a few alarms on my VM environment about Guest CPU Usage. Tracked it down to my fog server which I then found was chugging at 100% cpu utilization. Here is a screenshot of the “TOP” command run as root:

I am also getting many “Max children reached” messages in the php-fpm error log on the Web UI.

I am running 1.5.4 on CentOS7.
Thanks!

@sebastian-roth OP also mentioned separate virtual and physical environments. It just occurred to me he can use the physical server for his physical subnet utilizing one of the NIC’s and just spinning up a linux VM for FOGing on his Virtual subnet. No additional cost this way. Good thinking.

@fernando-gietz I feel foolish now. This taught me the lesson that I shouldn’t change multiple variables when trying to troubleshoot an issue.

Here is a screen shot of my working config:

I think I had an incorrect group search DN set. When I put the correct DN I also messed around with the Group Member Attribute. I changed it back to sAMAccountName and presto! Thanks for everything boys!

Kinda bumping this thread/trying to help. Kind of thinking out loud, but this would involve 2 IP helper addresses on the networking side, two DHCP option 66 ip addresses, and somehow specifying 2 IP’s on the FOG server itself.

Does FOG handle your DHCP?

@fernando-gietz Is there a different way in the DN language to designate spaces? I tried single and double quotes but it didn’t stick. In the actual AD structure (much to my chagrin) there are spaces.

@fernando-gietz I believe I have successfully bound. However, when I try to log in as myself, I see the below error in /var/log/php-fpm/www-error.log

I believe the issue is in my search dn.

I am trying to log in as fry_p. I am a member of the security group “fogusers” in AD. It can be found here:
CN=fogusers,OU=Security Groups,OU=Domain Users,DC=domainhere,DC=org

fry_p is a member of this group.

@fernando-gietz Does the built in Domain Admin have such permissions? That’s the account I am using.

@JGallo Yes, sorry I forgot to mention that. My colleague mentioned the 636 is the one he wants me to use, but I did try both.

FOG 1.5.4
Centos 7

As a security/accountability measure, we would like to incorporate LDAP/AD Authentication to the FOG GUI. I am having a hard time getting it to work. Besides filling out the LDAP setup, is there another step to allow LDAP authentication?

Please see below for a sanitized version of what my LDAP setup looks like.

As always, thanks for the help!

@george1421 I made the changes but it got me thinking. I’ve been meaning to rebuild our FOG server on a more proper OS (Centos 7), so on Friday night, I did just that. I’ll let you know if I have any issues with mass unicasting now, but the variables have changed. I feel a lot better about the stability with the new install for now.

@george1421 We will be doing an exorbitant of lab re-imaging this summer, so testing will not be an issue. I will do this and certainly report back. Probably in the next few days.

@george1421 20 unicast deployments. I also seemed to have triggered it when truncating the imaging log in mysql.

Hi @george1421 ,
At present, things seem quiet, but here are screens of system monitor on ubuntu:

Top CPU usage:

Top Memory Usage:

So yeah, when not in crisis mode, things seem normal to me.

Ubuntu 14.04
FOG 1.5.3-1.5.4

I have run into a strange issue ever since updating to 1.5.3 and they continue onto 1.5.4. It all started when I went to image a lab of 27 PC’s the other day. We pxe booted and quick deployed each client (the way we do it all of the time). Everything seemed to be going fine, 20 hosts started imaging and others sat in the queue (our max clients on the storage node is 20). I walked away and came back and the lab was in various states of errors. I saw some had quit imaging partway through and others never started. I didn’t catch the actual error as we went into panic mode, but it said something about being unable to open the web server at our fog’s IP address. I went to a non-imaged PC and tried to get to the web interface. It timed out. I was thinking about the apache2 service crashing, so I checked its status. It appeared to be running, but I restarted it. No change. I rebooted the FOG server and shotgun upgraded to 1.5.4. I also noticed on the Vsphere console that memory usage spiked to the top (8GB). The combination of this brought it back up. This was 2 days ago.

Today, I tried to wipe the imaging log as it had built up about 3 years of entries. I also tried to update the Kernel to Tom Elliott 4.17.0. The UI became unresponsive and if refreshed, timed out. Same thing happened afterward. I was unable to Pxe boot to FOG. I restarted the Apache2 service and rebooted which made it responsive once more.

Prior to the 1.5.3 update, everything seemed stable. I am now worried about the reliability of my FOG setup. Please let me know any logs I can provide to help troubleshoot.

Thanks!
