Updating a File's Timestamp with Touch

You can use the Unix touch command to modify a file's timestamp. The syntax is touch -t STAMP where the timestamp is in the form

[[CC]YY]MMDDhhmm[.ss]

CC - century, e.g. 19 for twentieth century or 20 for twenty first century
YY - year
MM - month, use 01 for January
DD - day, use leading zeroes, e.g. 01 for the first day of the month
hh - hours in 24 hour format, e.g. 13 is 1:00 P.M.
mm - minutes
ss - seconds

Note: brackets denote optional parameters.

E.g. touch -t 200402132233 myfile.txt resets the timestamp on myfile.txt to February 13, 2004 10:33 P.M.

Configuring the Telnet Service for NT Authentication

Normally the telnet service will allow transmission of passwords in plaintext, i.e. in unencrypted format. Someone with a sniffer can learn the userid and password if unencrypted passwords are allowed. So ensure that only NT authentication is used, which will prevent plaintext passwords from being used to make the connection.

1. Click on Start
2. Select All Programs
3. Select Accessories
4. Select Command Prompt
5. Type tlntadmn config sec=-passwd and hit the Enter key. You should see "The settings were successfully updated."
6. You can check the settings by typing tlntadm. For "authentication mechanism" you should see only NTLM

Note: If you wish to see other options for the tlntadm command you can type tlntadm /?

Specifying Telnet Clients

Under Windows Small Business Server 2003, you must also stipulate which userids are allowed to make Telnet connections to the server. To do so, take the steps below.

1. Click on Start
2. Select All Programs
3. Select Administrative Tools
4. Select Active Directory Users and Computers
5. In the right pane, double-click on Telnet Clients
6. Click on the Members tab
7. Click on Add
8. Under Enter the object names to select, put in the userids for which you wish to allow access
9. You can click on Check Names to check the validity of names you have entered
10. Click on OK when finished
11. Click on OK again at the TelnetClients Properties window
12. Click on File then Exit at the Active Directory Users and Computers window
