I use TCP Wrapper to allow service install on solaris. Syntax for /etc/hosts.allow is daemon and ip to allow but my problem is I don't know what is daemon name. An application is not well know. Can I specify port number in /etc/hosts.allow?

please see link below for syntax:

I could not see any example showing that you can specify the port, but you can control the connecting IP source

My problem is I don't know daemon name. It is apache. I enter httpd , /PATH/httpd. They don'twork. Moreover another applications is not well known.

I think you can use ALL or unknown in the application field (if I remember correctly, you may check the link).

If  I use "ALL" the other application won't block. I want to allow some applications.

One key issue here is that not all daemons are compiled to use the TCP_Wrapper feature. The inetd daemon is, and thus can provide the service for all daemons that it starts (at least in nowait mode). You need to make sure that the daemons you want to control here are in fact tcp_wrapper capable.

Depending on you version of Solaris, you might want to use IPFilter instead.
