Re: disabling "rogue" login hooks on [bsd type ] apple mac os x snow leopard-problem

thanks, i'll certainly try this, but in case i will be unable to
locate the thing, maybe i wasn't totally clear -  either. what i want
to achieve is to purge logon exec sequence to it's default state-os x
does this by default but the -pf parameter sent to login process
overrides this default behavior what i'm trying to cancel this but i'm
unable to because the said control file is not in the location where
it was just  a month ago. i was wondering if there was some hidden [or
not hidden ] unix command that would force process control prefs back
to it's stock defaults.

I might not have been clear don't grep for the file but grep for the command
that is opening the ports perhaps max OS in all its glory has renamed or
consildated the file somehow so it isn't "there" anymore and has a new name
or has been appended to another file . That kind of thing.

Otherwise you could have some file corruption that is hiding the file from
you but the system can see it to execute it.  It might be better to backup
and reinstall.

You could also grep the /dev/<hardrive_partion> for the command that is
opening the ports

Have you tried booting off another OS X install mounting the drive and
editing it from there. perhaps using grep to find the file containing the
command that opens those ports perhaps it just isn't where you are
expecting
it.

hello group,
i have a question regarding deactivation of login hooks on Mac os X
10.6 snow leo
some time ago i've written some debug script for my OS X root account
-now after fixing disc permissions the script has reactivated ad gone
rogue [disapeared from it's directory so i'm unable to delete]
when i login to Terminal i get
$ ps
....other processes
login Marcin
when i type sudo su -
*password here*
i get the unwanted script execution
ps shows
login -pf Marcin
as a login process and i'm stuck cos only way i know of turning off
login hook is deleting the script from disk the com.apple.preferences
file with the dir pasted [apple's advice on creating login hooks] is
entirely non-present in given location
as this script opens few ports for net debug it poses sec threat and i
really desperately need to turn that login hook off
please advise and thanks in advice

take care
