Java Restricting access to a machine by IP Address

I have a need to allow only certain IP addresses to access a machine running solaris 9. I am not sure how this can be accomplished.

Thanks in advance for your help.

solaris 9 come with tcpwrapper which you can use to restricte access to certain ip address.

To enable tcpwrapper edit /etc/inetd.conf or /etc/inet/inetd.conf
to restrict telnet access

Do the following:
change this

telnet stream tcp6 nowait root /usr/sbin/in.telnetd in.telnetd

to

telnet stream tcp6 nowait root /usr/local/bin/tcpd /usr/sbin/in.telnetd

then edit /etc/hosts.allow and put the entry

in.telnetd: x.x.x.x

also

edit /etc/hosts.deny and put the entry

ALL: ALL

You can also do the above to restrict ip access for ftp, rsync, rcp,ssh and so on

Note

x.x.x.x is the ip address you want to allow access, it can also be in form of x.x.0.0/255.255.0.0
