I was wondering where in UNIX is file where I can delete hosts that can or ca not access UNIX machine

thanks in advance

Try using /var/adm/inetd.sec. This will allow you to set access control to your system. Check the man page for details.

thanks but I have inet in folder /etc/inet/inetd.conf and there is in this folder

also I am trying with /etc/inet/routes and can I just delete

/usr/sbin/route add net 192.168.129 164.48.156.166 1 # Customer LAN
/usr/sbin/route add net 192.168.128 164.48.156.166 1 # Customer LAN
/usr/sbin/route add net 192.168.131 164.48.156.166 1 # Customer LAN
/usr/sbin/route add net 172.16.0 164.48.156.181 1 # VOMS21 VOMS22

one line or am I on right place??

thanks

or does anyone know how to forbid certain group of IP addresses to access my UNIX machine

have you tried looking for the manpages of hosts.allow and hosts.deny yet? It's not exactly pan-unix, but it's a good solution,

short of setting up some firewalls rules I think you're just going to have to use this and a couple different methods in order to achieve the desired results...

Hi!

Try using firewall (iptables). Lines like:
iptables -A INPUT -d ?address? -j DROP
define rules you need.

Files hosts.allow/deny are related (only) to services started by inetd and therefore after "suitable" settings sshd and httpd could be still accessible...
And purpose of /etc/hosts is completely different - it is something like static DNS.
