Okay, here is the question: I need to monitor a tty, a group of ttys (includi ng [pt]tty). Can I adjust the FIFO to pipe the info to a fil(like conlog)? If I tail -f,or cat the tty ports it skips an echo, and on the next line except s the input. This may be an easy thing to do, it should be but because of the user friendly manuals I can't seem to find the info I need. By the way I am the system admin, and we are having a security/abuse problem.

It has been done, with varing results using kernel (clist) hacking routines (for machines that use clists for tty processing). Streams ttys offer an easier interface. A module could be pushed on a stream tty which would tee off the output to another device which could be read by another process. I have written such a streams module a posted it to alt.sources a while back. It is called advise and allows a use to place his terminal in another user's terminal stream. The advising user can send and receive i/o as if they were the advisse user. It only works on System V Release 4 machines, though so it may not be of much help to you.
