- Yes, and it's already being done for you, unless someone has disabled it.
-
- Try the ACCOUNTING command. HELP ACCOUNTING should give you an idea of the
- possibilities. ACCOUNTING/TYPE=(LOGFAIL,PROCESS) is probably a good place to
- start. Add /FULL to get more information. Add /SINCE=time and /BEFORE=time
- to bracket a particular time period. Add /USER=username to see entries for
- just one user. (Note that this will suppress login failure messages where no
- username was recorded.)
-
- (One thing which is not recorded, unfortunately, is the terminal server and
- port name for logins (and attempted logins) via LAT ports.)
-
- While we're on the subject, you should do
-
- $ set accounting/new
-
- periodically, say once a day or once a week or so. This closes out the current
- accounting file (SYS$SPECIFIC:[SYSMGR]:ACCOUNTNG.DAT - note that it is not
- ...:ACCOUNTING.DAT) and starts a new one. Unless you do this periodically
- you will have one giant file which will take forever to search through (unless
- you have a very quiet system).
-
- It is almost always a good idea to back these files up to special archive tapes
- which are explicitly kept forever (rather than relying on the regular system
- backups) and then delete the ones that are too old to be of interest most of
- the time.
-
- There are several manuals in the System Management portion of the VMS Extended
- Documentation Set which you should read. _Guide to VMS System Security_ and
- the _VMS Accounting Utility_ manual come to mind. Check the _System Management
- Master Index_ for other references to the accounting log file.
