Programs have to be inetd-aware to be launched by inetd. This is not difficult; inetd just sets up the TCP socket as stdin/stdout for the program, so the program doesn't have to do anything. The most important thing about choosing whether to use inetd or long-lived standalone daemon is the number of times the program will be called and the amount of startup time required by the program. Squid has a relatively long startup time, and will be launched a lot, so is not really suitable for calling out of inetd. Note that you could use something like ipchains or netfilter to control whether or not you can connect to squid (or any service) from the outside world. In addition, squid has configuration options that let you specify which network ports it will listen on, so if you don't want it listening on an external address, you can just tweak the configuration. Assuming that you only want to allow squid connections from localhost, then (depending on the squid version), you would use either: http_port 127.0.0.1:3128 or tcp_incoming_address 127.0.0.1 -- Dave Carrigan ([EMAIL PROTECTED]) | Yow!
