I am posting this because i am not sure its related virtualbox problem or an
inter ubuntu one...
I have vb running on gutsy host with feisty as the virtual machine os because I need it for some test scenario.
I want the vm to mount some gutsy folder via nfs. Due to several problems with bridging mode is only nat mode possible.
Problem is i always getting permission denied when I try mounting.
So it seems to me that server is accessible.
this is the network the vb nat engine is using
/dev/vg/backup /backup reiserfs defaults 0 0
tigger:/backup /nas/backup nfs defaults,noauto,intr,hard 0 0
sudo mount tigger:/backup /nas/backup/ -t nfs
mount: tigger:/backup failed, reason given by server: Permission denied
this is the only line I changed
STATDOPTS="--port 32765 --outgoing-port 32766"
Please have a look in the thread I have posted in virtualbox forums
Theres also the config for portforwarding in vb.
