---|
18 | .SH NAME |
---|

---|
20 | .SH SYNOPSIS |
---|
21 | .B access_on |
---|
22 | .br |
---|
23 | .B access_off |
---|
24 | .SH DESCRIPTION |
---|
25 | The |
---|
26 | .I access_on |
---|
27 | and |
---|
28 | .I access_off |
---|
29 | utilities control remote connections to Athena workstations. |
---|
30 | The workstation's |
---|
31 | .I reactivate |
---|
32 | process uses the |
---|
33 | .I access_off |
---|
34 | program to prevent the workstation's |
---|
35 | .I inetd |
---|
36 | daemon from accepting network remote connections. In other words, no |
---|
37 | one can access the workstation with commands like |
---|
38 | .IR rlogin , |
---|
39 | .IR rcp , |
---|
40 | .IR ftp , |
---|
41 | and |
---|
42 | .IR telnet . |
---|
43 | This protects the user from unexpected and possibly hostile remote connections. |
---|
44 | .PP |
---|
45 | Of course the user may wish to allow remote connections. |
---|
46 | The |
---|
47 | .I access_on |
---|
48 | command performs this function. |
---|
49 | Use |
---|
50 | .I access_off |
---|
51 | to prevent connections again. |
