Setup Issues and Error PXE E53

Wayne Workman

@Dalton-Childers You’ve ensured that firewall is disabled on the server?

Well if he can’t get the plane-jane undionly.kkpxe using TFTP - then there are other issues.

I was thinking either Firewall or TFTP is not running right or something - I don’t think this is a dnsmasq problem.

Can you check the status of TFTP and then restart it and then check the status again with these commands?

service tftpd-hpa status
service tftpd-hpa restart
service tftpd-hpa status

Then after you’ve restarted TFTP, please go to another computer and try to get the undionly.kpxe file manually via TFTP again.

Okay, so I restart the tftpd-hpa service.

service tftpd-hpa status
tftpd-hpa start/running, process 1104
service tftpd-hpa restart
tftpd-hpa stop/waiting
tftpd-hpa start/running, process 3039
service tftpd-hpa status
tftpd-hpa start/running, process 3039

I tried to get the unidonly.kpxe file again from a windows machine on the network using:

tftp –i 130.18.192.41 get undionly.kpxe

But I still get back the following error:

Timeout Occurred
     Connection Request Failed

tftpd-hpa file

# /etc/default/tftpd-hpa
# FOG Modified version
TFTP_USERNAME="root"
TFTP_DIRECTORY="/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"

Which I am wondering if the issue is the root username. Should the username be fog?

I disabled the firewall all together.

Also, I managed to get apt-get working again by following your suggestion to comment out “port=0”.

Steps:
Comment out “port=0”
rm /var/lib/apt/lists/* -vf
apt-get update

@Dalton-Childers Try the TFTP test locally on the FOG server itself. Try to use both the actual IP of the server and then try the local loopback address 127.0.0.1

Using the IP address of the server (130.18.192.41):

root@fog:~# tftp 130.18.192.41
tftp> get undionly.kpxe
tftp> get undionly.0
Error code 1: File not found

Due to a lack of experience with TFTP, I am assuming the lack of error for undionly.kpxe means it found the file. I tried undionly.0 because I know the file is not present under /tftpboot/.

Using the IP address of the server (127.0.0.1):

root@fog:~# tftp 127.0.0.1
tftp> get undionly.kpxe
tftp> get undionly.0
Error code 1: File not found

Same results as the server’s IP.

Tom Elliott

@Dalton-Childers So the simple test, you attempt to get the undionly.kpxe file, then you try to get the undionly.0 file. Because the undionly.kpxe file exists, you’re not seeing an error, but because the undionly.0 doesn’t exist, you’re seeing the error on the second command. This sound correct.

Now that you know that at the least the tftp server is operating locally. Now we need to see where it breaks down.

Wayne Workman

@Dalton-Childers @Tom-Elliott is right, and that was the direction I was heading with this…

Can you give us the output of this command first - it’ll let us know what’s going on with the sym-link.

ls -lahRt /tftpboot

Then - We need lots and lots of details about your VM setup because I think that’s where the problem lies. What are you using? How is the network setup? Is it using NAT or is it bonded or NIC sharing or what?

Can you install traceroute and then run a traceroute against Google’s DNS?

sudo apt-get install traceroute
traceroute 8.8.8.8

and give us the output of that please? This will tell us if you are using NAT or not. It’d also help greatly if you’d tell us you Router Address - the address of the target host if you can find it on your router - and perhaps some screen shots of your network setup for the VM?

Basically - the more details the better.

First request is listed below in the screen shot. The results of:

ls -lahRt /tftpboot

Information about setup:

I am running the Ubuntu 14.04 VM on my iMac using VMware Fusion 8 Pro. I have set a static IP which is “130.18.192.41” (including image of my network interface config). Our subnet is “255.255.254.0” and the overall range is 130.18.192.1 to 130.18.193.255. The architecture of the network isn’t completely known due to the nature of the main ITS group. Also, we have to be careful not to allow our PXE traffic to appear outside of our subnet. We have our own DNS in house, but the DHCP server is control by the main ITS group which is why I assumed I would need to use dnsmasq.

I have included a picture for clarity, but the VM is bridged with the iMac’s ethernet port so it appears as an additional machine.

The IP in the image “130.18.193.107” is the IP that is assigned to my iMac.

I don’t have access to the routers so I am flying blind on that end.

If there is anything extra that I should have added please let me know.

Wayne Workman

@Dalton-Childers At first glance of the results of ls -lahRt /tftpboot it would seem that your sym-links are not created, and that you have used copies instead. undionly.0 does not exist. (just informational at this point)

From your ifconfig output,
What is 10.0.1.2 ?
What is 192.168.2.1 ?

And - try to create this symbolic link and then try to network boot again:
ln -s /tftpboot/undionly.kkpxe /tftpboot/undionly.0

Here’s more info on symbolic links: http://www.cyberciti.biz/faq/unix-creating-symbolic-link-ln-command/

Please do not get discouraged. For many, Linux is a new adventure and the ‘path’ might not be as clear as it might be to an experienced MAC OS or Windows user - but to the experienced Linux user - it’s the same process as any other system… troubleshoot, test, troubleshoot, test - narrow it down, test, troubleshoot, test, narrow it down further, coffee, test, restroom break, test… it’s the same thing. If you know - it’s easy, if you don’t know, you figure it out. If you’re inexperienced - then you either try to figure it out and in the process learn a massive ton of Linux or you simply walk away because you refuse to give the effort… $:-\$ As long as you keep the communication going here, we will continue to try to help. It’s the same as with anything - if there’s a will there’s a way. No will, no way.

@Wayne-Workman @Tom-Elliott

I have created the requested sym-links, but still had no lucky with the PXE boot process.

10.0.1.2 is the IP address that my wireless card was assigned.
192.168.2.1 is the IP address of the private network on the iMac or at least that was my understanding. I have never changed that setting as it comes by default with VMware Fusion.

Has seen below I have created the sym-links:

I also bump the permission to 777. I was reading another FOG posting that suggested that has a possible fix.

I edited the dnsmasq.d/ltsp.conf file to related the sym-link change.

ltsp config.png

I also added in some more lines. I tested the tftp after creating the sym-link and then again after switch to undionly instead of undionly.kpxe.

I tried to pull the files from the server TFTP on my computer (iMac), my coworkers (PC), and my bosses (Mac Pro). The results were as follows:

Mine:

tftp> get 130.18.192.41:undionly.kkpxe
Received 103224 bytes in 0.0 seconds
tftp> get 130.18.192.41:undionly.kpxe
Received 103273 bytes in 0.0 seconds
tftp> get 130.18.192.41:undionly.0
Error code 256: File not found

Coworker:

tftp –i 130.18.192.41 get undionly.kpxe
Timeout Occurred
     Connection Request Failed

tftp –i 130.18.192.41 get undionly.kkpxe
Timeout Occurred
     Connection Request Failed

Wit the Windows machine I also tried to specify a different download location “%HOMEPATH\Downloads\undionly.kpxe” and “%HOMEPATH\Downloads\undionly.kkpxe”. These result failed as well.

Bosses:

tftp> get 130.18.192.41:undionly.kkpxe
Received 103224 bytes in 0.0 seconds
tftp> get 130.18.192.41:undionly.kpxe
Received 103273 bytes in 0.0 seconds

I had him run the following line and his results were the same as mine.

Fun fact, but could me just looking to much into the problem. I downloaded nmap to my iMac and checked port 69 on my FOG server. The result are below:

Wayne Workman

@Dalton-Childers After a session via TeamViewer with Dalton, I found that his virtualized FOG server was not receiving any traffic from anything besides the physical computer it was running on and possibly the internet.

I did a tcpdump and transfered the file via TFTP to the host computer - and examined it with WireShark. We used the reported MAC address from the FOG server as a filter and a single packet showed up. However without a filter all the traffic from the hosting computer shows up.

I think that this problem is related to the VM setup on the iMac, and I recommended that Dalton try to install FOG on a physical machine using all the same settings - and see what happens, or to use a physical machine and have his Network Team change the DHCP options 066 and 067 for him so that he doesn’t have to use dnsmasq.

Just awaiting for a reply at this point to see what path he goes down and how it goes.

@Wayne-Workman @Tom-Elliott

I just wanted to let you guys know after a few more tries we were able to get FOG working inside our environment.

Wayne Workman

@Dalton-Childers How? What did you do?

A Former User

@Wayne-Workman

The credit can really go to my boss, but this is how it ended up working.

For the FOG setup on Ubuntu 1.2.0

Follow this guide: https://wiki.fogproject.org/wiki/index.php?title=Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server

Skip the “Additonal Steps for 12.04.4, 12.04.5, 14.04, 14.10” section

The ltsp.conf should look like this:

port=0
log-dhcp
tftp-root=/tftpboot
dhcp-boot=undionly.kpxe,{server name},{static server ip}
dhcp-no-override
pxe-prompt="Press F8 for boot menu", 3
pxe-service=X86PC, "Boot from network", undionly
dhcp-range={static server ip},proxy

Make the following changes to the interface order:

eth*
lo.inet*
lo.dnsmasq
lo.pdnsd
lo.!(pdns|pdns-recursor)
lo
tun*
tap*
hso*
em+([0-9])?(_+([0-9]))*
p+([0-9])p+([0-9])?(_+([0-9]))*
ath*
wlan*
ppp*
*

Without these changes DNSMASQ would break DNS lookups.

Fix MySQL otherwise it’ll wig out on you.

Edited /opt/fog/.fogsettings

snmysqluser="root"
snmysqlhost="localhost"

Set the database password
Ran sudo dpkg-reconfigure mysql-server-5.5

Fog services weren’t starting automatically:

Changed /etc/rc.local to look like this:

sleep 10
service FOGMulticastManager restart
service FOGScheduler restart
service FOGImageReplicator restart
exit 0

For some reason this made it work finally.

@Wayne-Workman

Also, in the file “dnsmasq.conf” at the end of the file uncomment the conf-dir.

It should look like this:

# Include another lot of configuration options.
#conf-file=/etc/dnsmasq.more.conf
conf-dir=/etc/dnsmasq.d
