Kernel update 6 hours later

[NDNtech]

17:25 sounds like about the time one of the upgrades claims to have went through, shortly before I left work. I’m trying to update using a different name as you suggested, and it sticks on the ‘moving to tftp’ step and no file is created in that dir

[NDNtech]

And I notice our group names are different in our ls, do those matter?

The short answer is I think you have a problem with your tftp server (it might not be running or accepting connections), the long answer is…

Some of the relevant files seem to be…
[LIST]
[]fog/management/js/fog.about.kernel-update.js
[]fog/management/js/fog.about.kernel.js
[*]fog/management/ajax/kernel-fetcher.php
[/LIST]
Looking at them, the kernel file is downloaded to a temporary location then moved into fog/services/ipxe when it is ready. It is moved by tftp so if you have a problem with your tftp server you are going to hit problems.
As a first step I would give the machine a quick reboot, then CONFIRM that you have disabled any firewalls (iptables/ufw whatever) and SELINUX disabled. After that we need to confirm that your tftp setup is OK, the best way to do this would be to follow the code in kernel-fetcher.php you could try doing the tftp commands manually and see where the problem lies. If that isn’t an option I would try some simple tftp get commands just to confirm that it is running, e.g. on your fog server
[CODE]
$ yum install tftp
$ cd /tmp
$ rm -f undionly.kpxe
$ tftp IP.OF.YOUR.FOG.SERVER
tftp> get undionly.kpxe
$ ls -lhrt undionly.kpxe
-rw-r–r–. 1 root root 100K Jul 14 22:46 undionly.kpxe
$ ps -ef | grep tftp
root 2854 1139 0 22:46 ? 00:00:00 in.tftpd -s /tftpboot
[/CODE]

Check your FOG Configuration->FOG Settings->TFTP Settings->FOG_TFTP_FTP_USERNAME/PASSWORD settings. Make sure they’re set correctly. Check the /var/www/fog/service/ipxe folder and make sure it’s permissions are fog:www-data.

Today I did a clean install, again, and this issue is back. There’s gotta be something else wrong here.

[CODE]# apt-get install tftp

I checked to make sure the username and password were correct as well.

[Tom Elliott]

Which issue is back? The kernel download issue or tftp open timeout?

If it’s the kernel download you’re referring to, what is the output of:
[code]ls -l /var/www/fog/service/ipxe[/code]

[ianabc]

OK, if you test the ftp manually can you put files etc., go to a client machine with vsftp installed and try to “put” a file
[CODE]
$ echo “test Test test” >mytest
$ ftp IP.OF.YOUR.FOG
Connected to IP.OF.YOUR.FOG
220 (vsFTPd 2.2.2)
Name (IP.OF.YOUR.FOG:iana): fog
331 Please specify the password.
Password:<PASSWORD OF YOUR FOG TFTP USER HERE>
230 Login successful.
Remote system type is UNIX.

Using binary mode to transfer files.

ftp> put mytest
200 PORT command successful. Consider using PASV.
150 Ok to send data.
226 Transfer complete.

7 bytes sent in 0.00 secs (159.0 kB/s)
ftp> quit
[/CODE]
You should be able to see that file in your fog user’s home directory
[CODE]
$ ls -l /home/fog/
total 4

-rw-r–r–. 1 fog fog 7 Jul 15 16:03 myfile
[/CODE]
Does that work on your system?

[NDNtech]

Well, both I guess. The Kernel looks like it’s downloading okay from the looks of the /tmp directory, but tftp won’t transfer it to /var/www/fog/service/ipxe.

[CODE]> ls -l /var/www/fog/service/ipxe

Could you try that ftp transfer that I did in my last post. Make sure you use the username and password from the fog settings page.

[NDNtech]

I wasn’t sure exactly how to do all of that stuff you listed, so I used FileZilla because I know it allowed for manual sftp transfers, I hope that’s the same thing. Here’s the output from FileZilla on a Windows machine:

[CODE]Status: Connecting to SC-Image…
Response: fzSftp started
Command: open “fog@SC-Image” 22
Command: Pass: *****
Status: Connected to [EMAIL]SC-Image@domain.org[/EMAIL]

Status: File transfer successful, transferred 16,384 bytes in 1 second[/CODE]

Output from FOG server:

[CODE]fog@SC-Image:~$ ls -l /home/fog
total 20
-rw-rw-r-- 1 fog fog 18304 Jul 15 18:24 isd.png
[/CODE]

[ianabc]

Hmmm… I think that might be transferring over ssh (port 22). If you know FileZilla well you should be able to tell it to use ftp (port 23) somewhere, but if not, you should be able to run the commands above on your fog server after installing an ftp client, e.g.
[CODE]
$ apt-get install ftp
$ ftp IP.OF.YOUR.FOG
[/CODE]

You should be prompted for your username and password, then you should try “putting” a file as above “put <FILENAME>”.

Any (small) file in the directory where you ran the ftp command should work, I created one by echoing some text into a file called myfile before running the ftp command (echo ‘test Test test’ > myfile).

[NDNtech]

From Windows CMD:
[CODE]H:>ftp 10.120.88.146
Connected to 10.120.88.146.

226 Transfer complete.[/CODE]

From SSH to FOG Server
[CODE]fog@SC-Image:~$ ls

[Tom Elliott]

try:
[code]ftp 10.120.88.146
user fog
enter pass
put c:/dfinstall.log /var/www/fog/service/ipxe/dfinstall.log
[/code]

[NDNtech]

Tom:

It transferred correctly

[ianabc]

That’s basically all that portion of the fog code is doing (ajax/kernel-fetcher.php), so I’m not sure what could be going wrong. The permissions on some of the files under services/ipxe look a bit odd, could you send the output of “ls -ld /var/www/html/fog/service/ipxe”, i.e. the ipxe directory, NOT it’s contents.

[NDNtech]

[CODE]root@SC-Image:/home/fog# ls -ld /var/www/fog/service/ipxe
drwxrwxrwx 2 www-data www-data 4096 Jul 15 19:22 /var/www/fog/service/ipxe
[/CODE]

[Tom Elliott]

Run this:
[code]chown -R fog:www-data /var/www/fog/service/ipxe[/code]

Please try again.

[NDNtech]

Okay, I ran the command and tried to install the kernel but it’s not moving out of /tmp
