SUMMARY: inetd[115]: exec/tcp: unknown service

I asked:

> I have a small network of a 3/80 server and three 3/80 diskless clients,
> all running 4.1.1_U1 with no patches.
> We leave the server running continuously, as it is our UUCP mail and news
> machine, but the clients are normally shut down over the weekend.
> Sometimes when booting up a client, it goes through the normal boot
> procedure to the initial login: prompt, but then gives the console message
> inetd[115]: exec/tcp: unknown service.
> The network is running NIS, and doing a "ypcat services" on both the
> server and client reveals "exec 512/tcp".
> - What kind of problem does this message indicate?
> - Why does it appear?
> - Can I ignore it, or should I reboot the client when it happens?

The consensus was that I probably had a blank line in my master
/etc/services file.

I did.
