gawk question

[daniel_I_l]

I tried to run the gaek program:

BEGIN {
"/inet/tcp/0/localhost/daytime" |& getline
print $0
}

and got the error:
gawk: prog:2: fatal: can't open two way socket `/inet/tcp/0/localhost/daytime' for input/output (No such file or directory)
but when I checked my /etc/services file daytime was listed as a tcp service in socket 13. What could the problem be?
Thanks.

/etc/services simply lists the port numbers registered with IANA. You must start a daytime server on your machine to make the command work.

How do I start a daytime server? Isn't it supposed to be started at startup?
Thanks.

The daytime service is not started manually, it's handled by the xinetd service. You just have to enable it.
In the files /etc/xinetd.d/daytime-dgram and /etc/xinetd.d/daytime-stream change the line that says "disable = yes" to "disable = no".
Then reload the xinetd service: /etc/init.d/xinetd reload

Daytime is an obsolete protocol that's mostly used in programming examples because its simplicity. It's useless as a time service. There's no reason to start it automatically at boot and it isn't even installed by default.
