My understanding is that you need to enable persistance when
using FTP in conjunction with Direct Routing or Tunnelling

for the Linux Director to associate the FTP data and control
connections with each other.
I thought ip_vs_ftp module was there to handle load balanced FTP
traffic, almost the same way iptables does it. Am I wrong ?
I'm pretty sure ip_vs_ftp only works with NAT not DR or TUN.
Using port 0 (i.e. all ports) seems the simple method.
But regarding persistence...
Assuming you have 2 FTP servers with shared storage (NFS or raid or
whatever)
If you loadbalance both without persistence wont the client prompt for a
password each time the server changes ?
Is this the same if you are load balancing SQL (MySQL,PostGreSQL,Oracle
etc..) ?
Has anyone got experience of load balancing servers that have passwords
in the protocol ?
