The possword-gmbber command procedure presented in the article ill i.i si rales a number of blunders: 1. 1 Inst, that "9/iDClT.-F-TRA\ r S' , crftp is completely bogus, in several senses of the word. Why bother faking a login and making up an error message whan you can just simulate a user validation erior and make it Look as though file User has mis- typed his password':' Simulating a login error and killing the prucess is a lot salcr than pntWUtmg the user fwho may not he all that stupid, even if lie is a system manager) with a series of obviously bogus "system* messages. 2. You can use Ihe DLL command 'āSTOP, 1 IDENTICā to logout without generating a message. This doesnāt require any privilege at a II In a program, you ean use SYĀ£$r)EI.PkC. 3. Lsrng iMyLāIKF to read llw username and password is foolish when you can use the READ command with the ā PROMPT and /ERR qualifierĀ®, Also, READ has a timeout Option. Gy the way, the default limrout count at login is .30 Seconds, not 30 seconds ?s implied iu Lhe article. A. She command procedure given doesn't use SET MESSAGE to get rid of any error tUKSftges which might possibly be generated if things go wrongā another potent ial source of user fip-uffs 1 hat something fishy is going on. Where VMS is ennee i ucd . the whole password -grabber concept is praci it a lly obsolete anyway, since VMS V 4 d rfir.es a terminal characteristic called "SECIJRESERVGRā which was designed specifically to foil p ssword-gra bber programs. When a Lenmnal line has rh iĀ® characteristic set, pressing the BREAK key At login Lsguaramted to disconnect any process running on file terminal. A few other notes: I ) Control -T isn't very useful at login tinte Reprated COnirol-YY immediately following ihe password arc more useful, but the āT>5SCTT ,Y" flag in the UAF prevents them from having any effect. 3) Using "890" aĀ® a file version number is silly. (Snppo.sc that version k9i or higher ahead v rxii-Ls.) The number you wanl is 337 67; thatās the maximum possible version number. RTEM: 3) The first āTrojan horse* procedure given should include the command ā"SET' DEFAULT SYSIUXrlN'" before the DELETE command which is supposed to gel ihl of the incriminating 1 XXIIN .COM tile. As operating systems go. VMS is very secure, and il's becoming more so with each new release. (Unfortunate but true.) According to T>FC, a Version of VMS will have the Defense Departments highest possible security raring within two or three years. 1ft parting, 1 offer you at 2600 a slogan for your masthead: 'Tlte road of access leads to- the palace of wisdom. ā Apologies 1o Will iam Blake. ] Dear 26Wf\ 1 noticed a problem in the password grabber described on ptige 3-49 of your July 1986 issue.
