Unable to connect to TFTP

2015-04-29T13:17:41Z

Wolfbane8653.3362: /* For Versions 0.33-1.x.x */

{{Merge|target=Troubleshoot_TFTP|discuss=Talk:Troubleshoot_TFTP}}
== Unable to connect to tftp server ==

=== For Versions Before 0.24 ===

This seems to be caused by a password issue,

1. From the fog management interface, go to users.
2. Reset the fog user password.
3. Click the "I" icon - "Other Information"
4. Click "Fog Settings" in the menu on the left
5. Replace the FOG_TFTP_FTP_PASSWORD and the FOG_NFS_FTP_PASSWORD fields under FOG settings with
your Linux fog user password. (Seems like FOG_NFS_FTP_PASSWORD is gone for ver .24).

=== For Versions .24-.32 ===

*Reset the local password for user fog with: [sudo] passwd fog
*In management front end, go to '''Storage Management''' -> '''All Storage Nodes'''
*Click on '''DefaultMember'''
*Change the '''Management Password''' to match the password you just changed.
*Then go to '''Other Information''' and change '''FOG_TFTP_FTP_PASSWORD''' also.

* Go to your fog web location, on Red Hat and CentOS is in:
/var/www/html/fog/

Then open the file:
/commons/config.php

and check the values of:
'''TFTP_FTP_PASSWORD''' and '''STORAGE_FTP_PASSWORD'''

These '''MUST''' match the password you set above, if not write them properly in here

Finally reload of the service

/etc/init.d/vsftpd reload

----
=== Verify Server Settings ===

If you have modified your server setup since first install, then the new changes must be updated and verified in the '''Fog Settings''' menu.
It might not be enough to just re-run the installer.
For instance, a new IP lease will cause the server to show the '''Unable to connect to tftp server''' error message.

* Go to the "I" icon, which is the '''About''' menu in 0.29
* Select '''Fog Settings''' and navigate down to '''TFTP Settings''' and verify that all options are correct for your setup.

=== Ensure nothing else on the network is conflicting with the DHCP server ===

I had this error the past two days and tried all of the standard suggestions. Finally Wireshark came to the rescue. I discovered a second, feral DHCP server on the network that wasn't issuing IP addresses but must have been running interference somehow. When I disconnected it from the network, PXE boot worked as expected.

Use FOG with FreeNAS

2015-04-27T18:13:08Z

Wolfbane8653.3362: /* Notes: */

== How to: Use FOG (1.1.2) with FreeNAS (Storage node - 9.1.1) ==

*I have often seen people want to use Fog Server with a Storage Node FreeNAS. At my office, it works so i describe you step by step how to do.
There are probably several solutions i think, but i propose you a simple solution that works with me.

I* consider that your FreeNAS is ok for the installation and NIC.

===Pre-Configuration===
*IP Addresses (These are not required but set as example)
**Fog Server: 192.168.56.102
**FreeNAS: 192.168.56.240

==='''FOG Server'''===

#'''Storage Management'''
#*Add the Storage node.
#*Storage Node Name: FNAS
#*IP Address: 192.168.56.240
#*Is Master Node: As you want.
#*Group: As you want.
#*Image Path: /mnt/Volume1/data/images
#*User/Pass: Free/Free (Not very secure ;) )
#'''Image Management'''
#*For your image, choose the storage group witch contains the new storage node.

==='''FreeNAS'''===

#'''Add Volume1'''
#*Storage -> ZFS Volume Manager:
#*Volume Name: Volume1
#*Volume layout: All the disk (in my case)
#'''Create the path'''
#*Clic on Volume1 -> Create ZFS Dataset:
#*Dataset Name: data
#*Compression level: inherit
#*Enable atime: inherit
#*ZFS Deduplication: inherit
#*Clic on data -> Create ZFS Dataset:
#*Dataset Name: images
#*Compression level: inherit
#*Enable atime: inherit
#*ZFS Deduplication: inherit
#*Clic on images -> Create ZFS Dataset:
#*Dataset Name: dev
#*Compression level: inherit
#*Enable atime: inherit
#*ZFS Deduplication: inherit
#*[[File:FreeNAS DirectoryStructure.png|border]]
#'''Create .mntcheck'''
#*On the folder "/images" and "/dev", create the file ".mntcheck"
#*CMD: touch .mntcheck
#'''Create new user'''
#*Account -> Users -> Add User
#*Username: Free
#*Primary Group ID: Free
#*Home Directory: /mnt/Volume1/data/images
#*Home Directory Mode: 777
#*[[File:FreeNAS User.png|border]]
#'''Permission for the path'''
#*Storage -> clic on data/images -> Change Permissions
#*User: Free
#*group: Free
#*Mode: 777
#*Type of ACL: Unix
#*Set Permission recursively: YES
#*Verification: cmd: ls -laR /mnt/Volume1/data/images
#'''NFS'''
#*Don't edit "/etc/exports". In my case, when i restart the service, the file faded. I had to WEBGui.
#*On the left.
#*Sharing -> Inux (NFS) Shares -> Add Unix (NFS) Share.
#*Comment:...
#*Authorized networks: 192.168.56.0/24
#*All directories: OK
#*Maproot User: Free
#*Maproot Group: Free
#*Path: /mnt/Volume1/data/images
#*OK.
#*[[File:FreeNAS NFS.png|border]]
#*
#*Idem for the folder "/dev"
#*
#*[[File:FreeNAS dev.png|border]]
#*Verification:
#*cmd: cat /etc/exports
#*[[File:FreeNAS Exports.png|border]]
#'''FTP (I don't know if it's really necessary)'''
#*Services -> FTP -> Advenced Mode
#*Path: /mnt/Volume1/data/images
#*File Permission: 666
#*Directory Permission: 777

===Uploading Image===

*Now: you can upload your client
*Problem, you may also get an error message at the end: FOGFTP: failed to rename file.
**http://www.fogproject.org/wiki/index.php/Images_Directory_Permissions

*Method 1 doesn't works with me, so i use method 2. [[Use_FOG_with_FreeNAS#Notes:|*]]
*[[File:FreeNAS FTP Will Not Rename And Move.png|border]]
*CMD: cp -a /mnt/Volume1/data/image/dev/@MAC /mnt/Volume1/data/images/NameOfYourImage
*cp -a to keep the same permission.

*'''That's it.'''
