Shared file system across a firewall

[DonDavisFCB]

I need to connect 4 application servers to a single shared filesystem running on a HACMP server on the other side of a firewall. I cannot open firewall ports that would cause risk. I have looked at NIS+ and tunneling NFS through SSH.
None seem to be a secure or workable solution. The tunneling through SSH won't work because file locking won't pass through the tunnel. NIS+ and SNFS open too many insecure ports.
AIX5.2 ML04

Any suggestions?
Thanks

How about loading Samba on the main server and sharing the direcory?
AIX 5.2 and above include the CIFS filesystem support, so you should have it on your installation media.
mount -v cifs -n sambaserver/myuser/mypassword /remotefs /localfs
As far as I recall, you would need ports 137,138,139 & 445 TCP & UDP to be opened. (The same as what would be defined for file sharing on Windows servers)
