@Wayne-Workman as suggested by @george1421 I am moving all my files to a folder called /opt/bootimgs on my Linux box
-
@Tom-Elliott removed the suggested lines from the command same result

Because your boot menu is using http, you would still need to create a soft symbolic link from this new directory to somewhere in the web directory.

Ok how do i create this soft link?
-
@dureal99d The syntax is:
ln -s <source> <destination>You should remove the left/right carrots when running the command.
If all the ISOs are in /opt/bootimgs the command would be:
ln -s /opt/bootimgs /var/www/htmlOf course, apache needs access to this new directory also. It’s fine to set ownership of
/opt/bootimgsto apache:root or 777 or something.And your resultant web path to these files would then be:
http://<IP>/bootimgs/whatever -
@Wayne-Workman ok ima get on it and post the results shortly
-
@dureal99d after setting the new nfs paths, did you run
exportfs -a -
Also may be useful to see the exact command you’re typing now.
-
@Tom-Elliott sudo mount 192.168.1.109:/opt/bootimgs/fedora /mnt
-
@Tom-Elliott no, i didnt know i had to, but will try it

exportfs -a
exportfs: /etc/exports [3]: Neither ‘subtree_check’ or ‘no_subtree_check’ specified for export “*:/var/www/fog/service/ipxe”.
Assuming default behaviour (‘no_subtree_check’).
NOTE: this default has changed since nfs-utils version 1.0.xexportfs: /etc/exports [4]: Neither ‘subtree_check’ or ‘no_subtree_check’ specified for export “*:/opt/bootimgs/fedora”.

@dureal99d those messages are fine
Any luck mounting now? -

@dureal99d can you post your exports file again?

/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)
/var/www/fog/service/ipxe *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)
/opt/bootimgs *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure) -
@dureal99d That’s the issue you can’t mount a full path. Only mount up to the bootimgs folder.
Instead of:
mount 192.168.1.109:/opt/bootimgs/fedora /mntuse :
mount 192.168.1.109:/opt/bootimgs /mnt -

mount 192.168.1.109:/opt/bootimgs /mnt
mount: wrong fs type, bad option, bad superblock on 192.168.1.109:/opt/bootimgs,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)In some cases useful info is found in syslog - try dmesg | tail or so. -
@dureal99d and output of
dmesg | tail -20? -
