@george1421 At last I succeeded to network boot latest Bitdefender Rescue CD

What helped me is when I dropped to the client shell, I saw /lib/modules/$KERNEL/modules.order was listing nfsv3.ko, nfsv4.ko & other .ko files related to nfs, but they were missing in /lib/modules/$KERNEL/fs/nfs & /lib/modules/$KERNEL/fs/nfs_common …

Basically what I did is extract init file (initfs.i386-pc) file provided in Bitdefender’s iso and extract the filesystem (livecd.squashfs)
Then rsync both /lib/modules/$KERNEL/fs/ directories to inject missing .ko files in the initfs, and recompress to a new initfs. Then modify ipxe settings to point to the updated initfs.i386-pc and …
IT WORKED

I guess you can mark this one as solved, if you want I can detail all the steps or provide the working initfs.i386-pc file. Thanks for your support

@george1421 I totally share your point of view. Be sure I’ll let them know

@george1421 There isnt /var/log directory at all,

dmesg doesnt return any error, this all I found regarding NFS :

Honestly I m kind of stuck right now, I came here because I really have no clue …

@george1421 I can’t find any logs at all when Im at the linux shell

On the fog server nfs supports v3 & v4 :

I edited nfs server conf to enable v2 support

Same result from the test client with vers=2 :

Sorry I wasn’t clear enough so I took a few captures, hopefully it will help :

Here is the error I get with my diskless test client

Drop to the shell and trying to manually nfs mount the fog server :

Then nfs mounting the fog server from my Ubuntu 18.04 host :

As you can see, it worked :

I am trying to network boot Bitdefender Rescue CD (latest iso file downloaded from bitdefender’s website) following instructions from the wiki : https://wiki.fogproject.org/wiki/index.php?title=Include_any_ISO_in_the_FOG_Bootmenu#Bitdefender

PXE booting client => I get NFS mounting failed error. From the shell I can’t mount X.X.X.X:/images/dev neither with nfs version3 nor v4 (NFS server supports v3,v4 UDP & TCP).

lsmod shows NFS module is loaded. I tried on another ubuntu machine and I succeed to mount no matter which NFS version I use, so I guess the server side is working. I also tried with Fog 1.5.6 & got the same result.

I spent quite some time on this one so I’d be happy if someone could help me. Thanks alot
