I have tip configured to use ttyi07 to get somewhere. While in use, /usr/spool/locks/LCK..ttyi07 exists, which should be deleted when tip is exited. However, the lock file only gets deleted if the user is in the daemon group! Wierder still is that the non daemon group user has no problem deleting the lock manually after exiting tip. Can anyone explain this? Some relevant facts: /usr/bin/tip - mode = ---s--s--x, owner = UUCP, group = daemon /usr/spool/locks - mode = -rwxrwxrwx, owner = UUCP, group = daemon Thanx. -- Ken Spagnolo - Systems Programmer, Postmaster, Usenet Administrator, etc. Computer Centre, Massey University, Palmerston North, New Zealand K.Spagnolo@massey.ac.nz Phone: +64-63-69099 x8587 New Zealand = GMT+12

Yes, I realize why anyone can delete files from a 777 directory. My original posting was poorly worded in that this seemed to be the main point, perhaps. I only though it a bit strange because I figured there might be unusual permissions on /usr/spool/locks which prevented the deletion of the tip lock file upon exiting tip. Thanx for all the responses, but I still need to know how to make tip delete the lock automatically. -- Ken Spagnolo - Systems Programmer, Postmaster, Usenet Administrator, etc. Computer Centre, Massey University, Palmerston North, New Zealand K.Spagnolo@massey.ac.nz Phone: +64-63-69099 x8587 New Zealand = GMT+12
