Question : Highly available FTP server solution

I am trying to setup a highly available ftp server running on Linux or Solaris.  Has anyone had experience with this or can suggest how to go about setting one up?  I am thinking of setting up 2 clustered ftp servers (active/passive) connected to external storage.  Can anyone recommend a secure, dependable FTP server to run on Solaris or Linux?  Also, any recommendations of good Clustering software?

Thanks.

Answer : Highly available FTP server solution

On Solaris:

Sun Cluster, Veritas VCS, and Stone Beat come to mind.

Sun Cluster doesn't have a canned FTP module - but someone familar with Sun Cluster should be able to build a FTP scalable service without much issue.  I would also include a Scalable IP resource and tie the FTP service to this IP resource.  Sun Cluster isn't free.

Veritas VCS - same comment - someone familiar with it could write a service for this without much problem.  Like Sun Cluster, VCS isn't free.

Stone Beat has *MUCH* less support for stuff like that it appears.   I have no experience with StoneBeat but its value compared to Sun Cluster and Veritas VCS seems to be very lacking.

Of the three, I'm most familiar with Sun Cluster and vaguely familiar with VCS.  Both are good products and both products have their fans.

On Microsoft:

Pretty sure IIS has a clustered FTP capability - oh wait, this is the Solaris forum ... forget I said that.

On Linux:

This is probably very appropriate.
