bf740959 | 46 | .Nm |
4fe2af09 | 47 | copies files between hosts on a network. |
48 | It uses | |
bf740959 | 49 | .Xr ssh 1 |
50 | for data transfer, and uses the same authentication and provides the | |
51 | same security as | |
52 | .Xr ssh 1 . | |
53 | Unlike | |
54 | .Xr rcp 1 , | |
55 | .Nm | |
56 | will ask for passwords or passphrases if they are needed for | |
57 | authentication. | |
58 | .Pp | |
59 | Any file name may contain a host and user specification to indicate | |
4fe2af09 | 60 | that the file is to be copied to/from that host. |
61 | Copies between two remote hosts are permitted. | |
bf740959 | 62 | .Pp |
63 | The options are as follows: | |
64 | .Bl -tag -width Ds | |
433e60ac | 65 | .It Fl 1 |
66 | Forces | |
bf740959 | 67 | .Nm |
433e60ac | 68 | to use protocol 1. |
69 | .It Fl 2 | |
70 | Forces | |
71 | .Nm | |
72 | to use protocol 2. | |
73 | .It Fl 4 | |
74 | Forces | |
75 | .Nm | |
76 | to use IPv4 addresses only. | |
77 | .It Fl 6 | |
78 | Forces | |
79 | .Nm | |
80 | to use IPv6 addresses only. | |
bf740959 | 81 | .It Fl B |
82 | Selects batch mode (prevents asking for passwords or passphrases). | |
bf740959 | 83 | .It Fl C |
4fe2af09 | 84 | Compression enable. |
85 | Passes the | |
bf740959 | 86 | .Fl C |
87 | flag to | |
88 | .Xr ssh 1 | |
89 | to enable compression. | |
433e60ac | 90 | .It Fl c Ar cipher |
91 | Selects the cipher to use for encrypting the data transfer. | |
92 | This option is directly passed to | |
93 | .Xr ssh 1 . | |
f1278af7 | 94 | .It Fl F Ar ssh_config |
95 | Specifies an alternative | |
96 | per-user configuration file for | |
97 | .Nm ssh . | |
98 | This option is directly passed to | |
99 | .Xr ssh 1 . | |
433e60ac | 100 | .It Fl i Ar identity_file |
101 | Selects the file from which the identity (private key) for RSA | |
102 | authentication is read. | |
103 | This option is directly passed to | |
104 | .Xr ssh 1 . | |
105 | .It Fl l Ar limit | |
106 | Limits the used bandwidth, specified in Kbit/s. | |
107 | .It Fl o Ar ssh_option | |
108 | Can be used to pass options to | |
109 | .Nm ssh | |
110 | in the format used in | |
111 | .Xr ssh_config 5 . | |
112 | This is useful for specifying options | |
113 | for which there is no separate | |
114 | .Nm scp | |
115 | command-line flag. | |
116 | For full details of the options listed below, and their possible values, see | |
