When you restart, is it ok?

Are these hosts automatically having their pending mac addresses accepted? And are you on FOG 1.2.0?

Actually, I remember when I first started using FOG we had duplicate MAC issues. This was caused because I had “approved” pending MAC addresses - which included VMWare virtual networking adapters. These were all identical, since I had installed VMware Workstation on a base image and it had retained the same address on every PC.

@Tom-Elliott

Last update is 10 months ago. It really doesn’t reflect the state of FOG or the work thats been done.

And I don’t mean that to come across like a dig at all either - quite the opposite. Maybe by “feature” I mean someone to take charge of updates to the news page.

@Wayne-Workman

They aren’t static, but they do retain leases for a long time. At the campus here, the ICT services department control the DHCP server that gives our machines their IPs and the DNS servers. We have some control (over AD groups and users and group policies and - to a degree - our switches and physical infrastructure) but not when it comes to DHCP/DNS operation. So we are stuck with IPs.

Which is fine, we can find which PCs are which IPs. I would have thought that a host could identify itself when the FOG service first starts and update its record that way, but I wouldn’t have thought NetBIOS pinging was really the way to go for communication with hosts when IP and MAC addresses are used for everything else.

…and I don’t just mean about major releases (IE https://fogproject.org/news/)

I think one place - maybe the Wiki main page - would be useful to have some sort of update now and then; topics such as an imminent client update, the forum upgrade or the recommendation for people to move to the development build are all significant topics that should get a story of their own and not get lost in the midst of replies to people’s issues.

(I am assuming that this actually doesn’t exist already - if someone corrects me, I’ll delete this . But it needs to be made more visible!)

It won’t use any rearms at all unless you actually run sysprep. If you do run sysprep and you don’t want it to rearm, just include Skiprearm set to 1 in your unattend file.

Here’s a bit of my unattend file so you can see where the SkipRearm bit should be:

<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:sc....
    <settings pass="generalize">
        <component name="Microsoft-Windows-Security-SPP" .....
            <SkipRearm>1</SkipRearm>
        </component>
    </settings>

As for not being activated - I found it annoying and activated in the end, since you have something like 3 rearms you can use. But I think it at least affects Windows updates so if you wanted to include those on your image, then activate once if you can.

(First of all - I’m not particularly experienced with using php. Feel free to explain things to me about it as if I’m very new)

Having DNS records stored is just impractical for where our FOG environment is. So we want to just be able to use IP to ping hosts or something.

Ss I understand it, the *hosts *table is populated with a host’s IP address. Why isn’t this used for pinging instead of the netbios hostname? I had a look at the php file for pinging and it looks like its to do with system overhead of making a ping call?

So my questions:

• Why are hostnames used instead of IPs - is it as above?
• When do IPs get stored and are they ever updated?
• Is this another thing that has been overhauled in trunkfog?

Cheers guys!

(I saw your reply just after I posted this, so ignore it if you’ve fixed it!)

Try these and tell me which works:

The one I think should work
(assumes you’ve set a DB password)

Edit /opt/fog/.fogsettings
The following are blank and need to be filled:

• snmysqluser=“root”
• snmysqlhost=“localhost”

Afterwards, run dpkg-reconfigure mysql-server-5.5 and give the same password to reset the mySQL database password

Or try this

sudo service mysql stop
sudo service mysql start

Does this now make the interface work whilst youre logged in?

If all else fails, try this and see what happens on next boot

echo manual | sudo tee /etc/init/mysql.override

Are you absolutely certain it isn’t in the domain already in OU that the Active Directory settings point to?

We had some issues where someone had simply joined computers to our domain without placing it in our department’s OU. Result was we had no rights to move it around and had to call another department to get it removed.

I was fairly sure that FOG could rename PCs and have that information update the computer account on the DC, so long as the right service account is used. I renamed a room of computers here and this resulted in computer accounts being created for both old and new names, rather than renaming existing names.

@Timtrag12

With the dnsmasq issue, I bet its because of the way it seems to kill dns lookups. In short, you just have to change the order of interfaces in /etc/resolvconf/interface-order - just put eth* first in that list. Give that a go, restart the server, and see what happens.

If you’ve changed your IP address, there are a number of files you need to change.

• /var/www/fog/lib/fog/Config.class.php
• use "grep -r <old fog server ip> /var/www/fog/lib/fog/ " and find any references you missed there
• /tftpboot/default.ipxe
• /etc/hosts
• /etc/dnsmasq.d/ltsp.conf
• /etc/network/interfaces

@Wayne-Workman

or Link the file

sudo ln -s -r undionly.kpxe undionly.0

But that shouldn’t be the problem, since you’re explicitly stating the file you want via TFTP. I’ll go with the idea its a permissions problem on the Windows side.

Running as a regular user:

C:\Users\Trevelyan>cd C:\Windows\System32

C:\Windows\System32>tftp 10.1.6.1 get undionly.kpxe
tftp: can't write to local file 'undionly.kpxe'

Running as admin:

C:\Windows\system32>tftp 10.1.6.1 get undionly.kpxe
Transfer successful: 103273 bytes in 1 second(s), 103273 bytes/s

What switches are you using?

I had a similar issue which was down to portfast not being enabled on the relevant switchports. I only saw this happen after I upgraded to 1.2.0.

After a day of using it, I actually really like it - so long as you can find a way to redirect old forum links for anyone who might have hardlinked to threads here!

What does the forum use now?

Yeah so in the “List all images” area, you still have to make them again. They exist, they’re taking up space, but you still have to have that image entry in FOG (it doesn’t automatically just pick up things dumped in the /images/ folder, for example).

Just make a new entry, give it whatever name you want, and then make sure you give it the right file path (as well as what OS you use and what type of disk it is - for example multiple partition, single disk)

When you say it isn’t the case, do you mean you get an error copying, get an error deploying or it just doesn’t show up?

(in case you didn’t do it - you still have to make the new image in the web management interface, with the path to your image)

FOG 1.2.0
University of Bedfordshire Computer Science and Technology Department
Luton, United Kingdom
Around 550 systems
Started using it in August 2013
Logo is something like here: http://surveys.beds.ac.uk/Uni_Bed_logo.jpg

Is this issue something that a lot of people will normally encounter though? Or just for Ubuntu [14.04?] users?

What kind of effect will this have if I don’t change it, other than having no logs to view? Tasks seem to still work as does multicasting and I would assume image replication too? (Although I haven’t got that working yet).

I’ll force a delay but keep an eye on any fixes that might come up. Cheers guys!

Yeah I am still looking through this - if the answer is on the forum, I’ll find it. Just the google links are broken and I’m trying to search for the same topics here

Cheers!
