When looking for dodgy directories I came across this:
crw-rw----    1 root     disk      12,   5 Mar 24  2001 tpqic24
crw-rw-rw-    1 root     root       5,   0 Mar 24  2001 tty
-rw-------    1 root     root     146882020 Jan 31 20:43 tty*
crw--w----    1 root     root       4,   0 Mar 24  2001 tty0
crw-------    1 root     root       4,   1 Jan 30 20:59 tty1
crw--w----    1 root     tty        4,  10 Mar 24  2001 tty10
crw--w----    1 root     tty        4,  11 Mar 24  2001 tty11
crw--w----    1 root     tty        4,  12 Mar 24  2001 tty12
crw--w----    1 root     tty        4,  13 Mar 24  2001 tty13
crw--w----    1 root     tty        4,  14 Mar 24  2001 tty14
crw--w----    1 root     tty        4,  15 Mar 24  2001 tty15
Just in case it is normal what looked odd to me was the 3rd line:
-rw-------    1 root     root     146882020 Jan 31 20:43 tty*

The time seems to correspond on with the time that I ran the find command.
Anybody know whats going on here or is this a rootkit of some kind?

Gracias
