Description

Toward to end of capturing my first image from a laptop - I suddeny saw “Error: attempting to update database failed” many times and then it rebooted and attempted the image task again - I stopped the process immediately - as I think it will surely fail again. I saw there’s a similar issue on this post :

https://forums.fogproject.org/topic/8201/error-returned-reattempting-to-update-database-failed/16

I’ve just chmod 777 images folder.
But the logs are a little different:

I deleted the ips - but just wondering if its related…

Good news I see the imaging process going through now. Problem fixed. Thanks Tom.

just saw your message. ok. I’m updating now. thanks.

p.s. I saw your comment “The line you’re seeing the error on please edit and remove the this-> part. It should work. I will fix shortly. Please follow exactly. Line 206 of the taskingelement file” . But when I click “this-> part”, nothing happens. Please advise if you are pushing a new RC fix and which file and part I need to modify. Many thanks

Hi Tom,

yes I see these repeated errors in the apache error log

I’ve successfully booted my laptop into Fog Menu and sucessfully registered the laptop. Now when I try to capture the image - on the laptop to keeps failing at “Attempting to check in - Failed” . and his repeats over and over again.

Hi Guys,

I have a new problem now. I’ve successfully boot into Fog Menu on the laptop and sucessfully registered the laptop. Now when I try to capture the image - on the laptop I see it keeps failing at “Attempting to check in - Failed” . and this repeats over and over again.

Good news . Problem solved. We had to add “next server” in our dhcp server. then everything works now. Thanks all for you help.

the lenovo is booting Both , but legacy first.

Thanks I got that message which shows tftpd service is running. I did the changes in the config and restarted but still having the same issue, even with the windows firewall turned off.

Hi george1421,

i have my pcap file ready, I wasn’t able to drop it into your chat box, it wouldn’t allow it . Do you have somewhere I can drop it off to like an ftp server or email add , etc ? Much appreciated.

oh no worries Tom, I figured out how to restart the tftpd-hpa. But same problem of the timeout and exiting on the laptop. I even chmod 777 to /tftpboot but no difference… however I am able to ftp to my fog server from my pc. So ftp is ok just tftp is not somehow?

Hi Tom,

Yes I’ve changed it so now /var/lin/tftpboot is a link to /tftpboot. But when I tried restarting /etc/init.d/tftpd-hpa , nothing happens. even ./tftpd-hpa status returns nothing. And the same process is still running…

root 24631 0.0 0.0 15128 148 ? Ss 13:50 0:00 /usr/sbin/in.tftpd --listen --user root --address :69 -s /tftpboot

Hi george1421,
I will try to send you the output.pcap file . I will see if I can just drop that file directly into the chat box

Hi george1421,

yes, that’s right , dhcp server, fog server, and pxe booting client are on the same subnet - the dhcp server is a juniper switch/router so it has the x.x.x.1 address

I found a better tool called tshark to format the pcap output. It’s pretty long , at least this is much more detailed and decriptive. Again I modified the actual ips with “” . please let me know what you find. Many thanks again.

Hi george1421,

Unfortunately no, I don’t see any of those in the pcap. The results I’ve pasted earlier is the full pcap. Does it mean the fog server isn’t talking to the dhcp server ?
I’ve verified the fog server , client and dhcp server are on the same network.

ok. I upgraded to RC36 now. I tried the tcpdump test again, and this time I got an output.pcap file so I used tcpick to unravel it. Here are the results, but I modified with open inverted commas for just the description :
