We use vsftp on RHEL7 for booting all our VxWorks IOCs; when converting
from Solaris to Linux we found that some other FTP programs weren't
compatible with some older VxWorks boot-rom versions anyway.
From the symptoms you describe it sounds like you might have a firewall
preventing the VME from getting to the server running on Ubuntu, or
possibly that the account the VxWorks system is trying to login as
doesn't exist on the Linux system or isn't enabled for FTP.
I would suggest that you use an FTP client program on a Windows PC to
try and fetch the VxWorks boot image from the Ubuntu server, and use
that to debug the connection. Once you can fetch the VxWorks image from
the Windows system, try booting the VME crate again (it's usually much
easier to troubleshoot when the client is another workstation).

The VxWorks boot-rom can be configured to use FTP, RSH or TFTP to fetch
its OS image at boot-time. RSH and FTP are probably easier to setup than
TFTP (I have never tried TFTP, it needs flag bits to be set).
