List-Unsubscribe: , List-Archive: Thanks for the reply. Got the 2.4.18 kernel. in make xconfig->file system->network file system, enable server side tcp support, and rebuild the kernel, reboot, start server side daemons, rpc.mountd, rpc.nfsd, rpc.statd ... One client side, do a mount server_ip:/dir1 /home/mydir -o tcp it gives : nfs server reported service unavailable: Address already in use.. Do I miss anything here ?
