Yes, there is always a limit, both for the OS and the user. pstat -T will give you some info on the system, limit -h (if your running a c shell) will tell you for the user. You can increase total system files either via sysctl or by increasing maxusers in your kernel config. ---Mike Mike Tancsa (mdtancsa@sentex.net) =09 Sentex Communications Corp, =09 Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers=20 could setup a national IP network."
