You would either need to use the tcp implementation in the kernel, or use the nfs-user-server. There is an article in the March 2002 issue of SysAdmin magazine on how to do it with Debian (shameless plug-- I wrote it! Ayman-- I meant to send this to this list before so you get two plugs!).

Also depending on what OS the server is running, you may be able to specify the ports that the rpc services run on. Also, depending on the OS, the tcp implementation may be stable (eg Sun, FreeBSD). Actually, I don't think tcp in 2.2.x is experimental anymore, it is just not particularly fast. I read on the LKML that tcp in the 2.4 series is now handled, but I haven't tried it yet. This would be in 2.4.18-pre or later. Jamie -- Email: [EMAIL PROTECTED] GPG/PGP ID: 26384A3A Fingerprint: D9FF DF4A 2D46 A353 A289 E8F5 AA75 DCBE 2638 4A3A
