| 11 | .SH NAME | |
| 12 | netlogin \- provide login name and password for a remote machine | |
| 13 | .SH SYNOPSIS | |
| 14 | .B netlogin | |
| 15 | .B \-m | |
| 16 | machine [ | |
| 17 | .B \-l | |
| 18 | login | |
| 19 | ] | |
| 20 | .SH DESCRIPTION | |
| 21 | The | |
| 22 | .I netlogin | |
| 23 | command sets the login name and password for the specified | |
| 24 | .I machine | |
| 25 | in a rather unusual way. | |
| 26 | The user should type (to the C shell) | |
| 27 | .IP | |
| 28 | setenv\ MACH\fImachine\fR\ \(ganetlogin\ \-m\ \fImachine\fR\(ga | |
| 29 | .LP | |
| 30 | or (to the default Version 7 ``Bourne'' shell) | |
| 31 | .IP | |
| 32 | MACH\fImachine\fR=\(ganetlogin\ \-m\ \fImachine\fR\(ga; export MACH\fImachine\fR | |
| 33 | .PP | |
| 34 | to his login shell. (Note the back-quotes). | |
| 35 | For example, | |
| 36 | .IP | |
| 37 | setenv\ MACHA\ `netlogin\ \-m\ A` | |
| 38 | .PP | |
| 39 | will prompt the user for his login name and password on the A machine and | |
| 40 | .IP | |
| 41 | setenv\ MACHA\ `netlogin\ \-m\ A \-l\ myname` | |
| 42 | .PP | |
| 43 | will prompt the user for the password to account `A:myname'. | |
| 44 | .PP | |
| 45 | The | |
| 46 | .IR net (\*s) | |
| 47 | command will read the environment looking for environment variables | |
| 48 | beginning with ``MACH'' and followed by a valid machine name on the | |
| 49 | local network. | |
| 50 | If found it will use that information rather than prompt the user | |
| 51 | every time he executes a network command. | |
| 52 | This environment information is ignored if login names and passwords | |
| 53 | are specified on the command line of network commands using the | |
| 54 | .B \-l | |
| 55 | and | |
| 56 | .B \-p | |
| 57 | options or in the | |
| 58 | .I \&.netrc | |
| 59 | file. | |
| 60 | .PP | |
| 61 | This procedure for specifying passwords is somewhat safer than | |
| 62 | putting the remote passwords in the | |
| 63 | .I \&.netrc | |
| 64 | file. | |
| 65 | The passwords in the environment are encrypted and the environment | |
| 66 | information is useless after the user logs out. | |
| 67 | Use the | |
| 68 | .IR printenv (\*o) | |
| 69 | command to see the encrypted password. | |
