Lethal - Multicasting should be as fast as Unicast yes, but if FOG is sending packets via UDP at 1gpbs, the switch would surely drop a lot of the incoming packets because it can’t send them out of the 100mbps fast enough (and thus lots of retransmissions)? Even with some buffering, whats coming in will be ~10 times faster than whats being sent out and thus it would be SLOWER, due to the constant re-transmissons and dropped packets

Ffor this reason also, I had an idea that a 10 host multicast was the most efficient thing to do and so far its seemed about right - a single host takes 1.5 hours, but 10 take just under an hour to do. My guess was; less retransmissions because of the slower rate to each host.

If one PC was slowing the rest down, that would show in the log (have had this issue on mixed speed rooms). But it seems like they’re all hiccuping from the log

As for the switch things… its tricky because we have no way to access the switches. I work in the academic computing department at a University - normally, all departments are managed via a central ICT department but we have moved away from their systems and recently decided to use FOG. They keep all their switches under lock and key pretty much, so even physical access is limited. However, it seems that the particular switch (note, there are many switches in a stack) has no other hosts on it as far as I can tell. There might be a phone or a printer somewhere but I have no way of knowing. I’ll make a note to ask - communication face-to-face is difficult as they have to manage the infrastructure for the entire University - which involves multiple campuses. So there is a growing list of things to ask!

The default quick reg value is PC-*

So you are successful in getting some of your units to speak to and load the fog splash screen, but a particular model of Toshiba minis will not connect?

Where does it fail? Do you receive a PXE error code when it attempts to pull the information, or is it skipping the PXE load all together?

Some machines have to have a specific driver built into the kernel before it can communicate properly. It doesn’t take much time and it is EXTREMELY easy to do. There is a wonderful walkthrough I will look for while I wait for you to answer my questions.

If I am understanding this correctly so far, your Toshiba Mini laptops are not receiving the TFTPboot information and are not displaying the fog splash screen therefore you are unable to register or image them and it continues to boot off the hard drive.

One other quick question. You said you had an Ubuntu server, what Ubuntu version are you using? 10.04? 11.04? 12.10?
Have there been any reboots of the server? there are some versions of Linux that have problems restarting some of the services after a reboot, we’ll cover that if necessary.

i schedule tasks directly into the database. it never works from the web ui.

WOL only works with me if the computers we shut down via windows shutdown. If they have been powered down by pulling the cord or holding the power button down for 3 seconds, WOL doesnt work for me.

update: i use this how to but nothing changed…did i have to change the usernamen from fog to admin as well?

the other thing is every changed password is now in cleartext visible?!

[quote=“jmwalton, post: 12827, member: 697”]any updates on this?
I would really love the help![/quote]

No solution for this yet, except to wait for the new kernel release; I understand it’s a work-in-progress. In the end, I had to use Clonezilla for basic cloning in a VLAN.

Please refrain from posting similar questions in multiple forums, this makes it hard for users to find answers when using the search system, and it makes it harder on those of us dedicating our time to try to help others.
Someone will be happy to assist you when someone with the expertise becomes available.

No, it is a Multiple Partition Image - All Disks.

Cant unserstand what the problem is…
Image is uploaded in 1 sec…pretty fast for 30GB :S

i have had this problem before it ended up being the graphics card driver, and our solution to this was to just use quick host registration and then change the host name ext in the fog console. then when it came to imaging we deployed the image and watched the progress form active tacks… it will get the job done if you need to finish up quickly.

p.s. you may need to restart the computer manually after the registration is done.

You’re going to need to review the threads here on using gPXE and interpret them to apply to proxy-dhcp/ltsp/dnsmasq. It should not be that difficult, you’re just going to hand off from pxe to gPXE, then grab the correct menu and go from there. The only difference may be the location of your pxelinux.0 file and the pxelinux.cfg directory location.

Always use the code tags when posting logs or code to keep the board from eating it and pooping out smilies.

Double check the information used for AD joining that is stored in the global FOG settings against the information that is stored in the Active Directory page for the particular host. Make sure they match, with the global FOG settings winning out over the host Active Directory settings if there is a difference.

can you catch the computer during boot up when the dell logo appears, and press F12 and get the computer to boot from the NIC card? if you don’t get the option to boot from the NIC card it isn’t enabled in the BIOS settings.

I just had this same problem with some brand new Dells. There is also a deep sleep mode in some Dell BIOS that needs to be turned off. Without this disabled, the NIC card isn’t even powered on to look for WOL packets.

I saw in multicast.log : "
Task (30) xxx failed to execute, image file not found!"

There is a bug : in multicastSessions table -> the msImage column have not the right value. Title instead of filename.

Zaza.
