| 39 | .Nd remote | |

| 42 | .Sh SYNOPSIS | |
| 43 | .Nm nfsd | |
| 44 | .Op Fl rut | |
| 45 | .Op Fl n Ar num_servers | |
| 46 | .Sh DESCRIPTION | |
| 47 | .Nm Nfsd | |
| 48 | runs on a server machine to service | |
| 49 | .Tn NFS | |
| 50 | requests from client machines. | |
| 51 | At least one | |
| 52 | .Nm nfsd | |
| 53 | must be running for a machine to operate as a server. | |
| 54 | .Pp | |
| 55 | Unless otherwise specified, four servers for | |
| 56 | .Tn UDP | |
| 57 | transport are started. | |
| 58 | .Pp | |
| 59 | The following options are available: | |
| 60 | .Bl -tag -width Ds | |
| 61 | .It Fl r | |
| 62 | Register the | |
| 63 | .Tn NFS | |
| 64 | service with | |
| 65 | .Xr portmap 8 | |
| 66 | without creating any servers. | |
| 67 | This option can be used along with the | |
| 68 | .Fl u | |
| 69 | or | |
| 70 | .Fl t | |
| 71 | options to re-register NFS if the portmap server is restarted. | |
| 72 | .It Fl n | |
| 73 | Specifies how many servers to create. | |
| 74 | .It Fl t | |
| 75 | Serve | |
| 76 | .Tn TCP NFS | |
| 77 | clients. | |
| 78 | .It Fl u | |
| 79 | Serve | |
| 80 | .Tn UDP NFS | |
| 81 | clients. | |
| 82 | .El | |
| 83 | .Pp | |
| 84 | For example, | |
| 85 | .Dq Li "nfsd -u -t 6" | |
| 86 | serves | |
| 87 | .Tn UDP | |
| 88 | and | |
| 89 | .Tn TCP | |
| 90 | transports using six daemons. | |
| 91 | .Pp | |
| 92 | A server should run enough daemons to handle | |
| 93 | the maximum level of concurrency from its clients, | |
| 94 | typically four to six. | |
| 95 | .Pp | |
| 96 | .Nm Nfsd | |
| 97 | listens for service requests at the port indicated in the | |
| 98 | .Tn NFS | |
| 99 | server specification; see | |
| 100 | .%T "Network File System Protocol Specification" , | |
| 101 | RFC1094 and | |
| 102 | .%T "NFS: Network File System Version 3 Protocol Specification" . | |
| 103 | .Pp | |
| 104 | The | |
| 105 | .Nm nfsd | |
| 106 | utility exits 0 on success, and >0 if an error occurs. | |

| 112 | .Sh HISTORY | |
| 113 | The | |
| 114 | .Nm nfsd | |
| 115 | utility first appeared in 4.4BSD. |
