Re: Startup network scripts

[Ajit Warrier <unixajit yahoo com>]

I have set dhclient so that it now does send the name
to the DHCP server and consequently gets registered in
the DNS server as well. Now when I run dhclient from
the terminal, it does everything correctly as
described. So that's a success!

However, when I restart the RHL9 unit, it once again
does not register the name. Once it has rebooted, if I
run dhclient from the terminal, it registers the name
with the servers.

My guess if that either dhclient is not being used by
my RHL9 client while booting up (it is a standard
"everything" install and I have changed nothing) or
the partitions the files are on, are not accessible at
the time dhclient is starting up. So my questions are
- 

1. How can I check to see what DHCP client is being
used during startup - dhclient or dhcpcd?
2. Is there a way to run dhclient after startup
explicitly? Is this a good idea?

Thanks for any help.
