Windows laptop unable to boot into Fog menu
-
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 :

tcpick: done reading from output.pcapAny ideas ?

@froydo (it would help if I could see the pcap, but 5 packets should be sufficient).
In the pcap you should see
Client: Discover->255.255.255.255
DHCP Server: Inform->255.255.255.255
Client: Request
DHCP Server: Ack
Client: tftp get -
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. -
@froydo Just for clarity your dhcp server, fog server, and pxe booting client are on the same subnet (no routers in between)?
If at all possible I’d like to review the pcap file in wireshark if you will post it here.

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.

@froydo Well I guess I’m not the one who can help you here. Its been a long day I don’t have the energy to try to decode the tshark output frame by frame.
If you are willing to post the complete pcap where I can review it I will.
Note: You don't have to post it to the forums, just direct message me a link. -
@froydo Stupid as this sounds, what happens if you simply change the /var/lib/tftpboot folder location to just /tftpboot and restart tftpd-hpa service?
-
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 -
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 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.
-
@froydo Another, and hopefully, final change.
The line of the config file that is looking only at :69 can you try:
0.0.0.0:69
and restart tftpd-hpa.
Yes, the restart is still needed.
Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)
Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

@Tom-Elliott The OP sent me the pcap file.
One remarkable thing found was there are two different dhcp server responses to the client’s discover packet. Each dhcp server is giving conflicting boot file and next server values to the client. In the pcap file there was no indication of the client asking the FOG server (assuming that is where the tcpdump command was being run) for the boot file.
@froydo on your fog server make sure your tftp process is running. The following command should show you the tftp server is listenting
netstat -an|grep 69You should see a line like
udp 0.0.0.0:69 -
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.
-
@froydo Maybe give dnsmasq and proxy dhcp a try?
It’s been a while since I’ve configured it but here are some possibly helpful articles
https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq
https://forums.fogproject.org/topic/5713/dnsmasq-breaks-apt-get -
@froydo Additionally, and I’m sorry if this was covered earlier in these posts and I missed it, is this laptop booting to legacy pxe or uefi pxe? It sounds like legacy pxe since its looking for pxelinux.0 in one error. But just want to make sure we’re helping you configure the right thing here.
-
the lenovo is booting Both , but legacy first.

@froydo said in Windows laptop unable to boot into Fog menu:
Hi george1421,
My dhcp server is a Juniper ex3300 and under the Boot options, there is the Boot Server , I entered my fog server ip there.
there is the boot file which I entered “/bzImage”. There’s no next server option anywhere I could see.So is your dhcp run completely by the switch? You don’t have a windows or linux dhcp service to manage things? Or did I miss something?
-
Good news . Problem solved. We had to add “next server” in our dhcp server. then everything works now. Thanks all for you help.
-
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.
-
@froydo Did you make a image entry in the gui to upload to?
I would also suggest for your first host and image doing the quick host registration and inventory from the menu then queuing an upload from the gui.
After you do a quick registration there should be a host in your hosts gui.
You’ll also need to make a image to assign to the host so it has a database entry to link to.If that doesn’t make sense check out https://wiki.fogproject.org/wiki/index.php?title=Managing_FOG or I can explain in more detail if you don’t find the answer there.
