The only reason I have for not running rwho is that one morning, back in the 1.1.57 days, when I got to the laboritory, my computer was swiched of, all cables disconected, panic notices were distributed around the room, and the sysadmin here were spreading panic messages like fire. Turned out the computer department had a problem with their system, and related it with my computer -- so the systemadmin here went compleately crasy. The only thing I could find in my syslogs before my computer was swiched off, were a few rwho messages. That's why I'd be weary to start that service up again, not because I'm on a 100 computer subnetwork: I don't really care if others see who's logged on here. (Yeah, I know you're not intereseted in this tragic story about computer abuse by systemadmins, but I'm still traumatised, and just needed to vent this). BTW, the systemadmin that went out of his mind back then has left, so maybe I can try starting rwho once more? I'm sure it wasn't rwho that was causing it, anyway. -- joost witteveen, [EMAIL PROTECTED] #!/bin/perl -sp0777i<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<j]dsj $/=unpack('H*',$_);$_=`echo 16dio\U$k"SK$/SM$n\EsN0p[lN*1 lK[d2%Sa2/d0$^Ixp"|dc`;s/\W//g;$_=pack('H*',/((..)*)$/) #what's this? see http://www.dcs.ex.ac.uk/~aba/rsa/ -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
