Sorry for the wrong wording: what I want is the DHCP client to send the hostname when a lease is requested, but I do not want to give dhclient any explicit hostname to be sent.
I want dhclient to read the hostname from `hostname` or from /etc/sysconfig/network or any other way, and use that name to send the hostname to DHCP server.
DHCP_HOSTNAME=$(hostname -s)
Yes, thank you.
Unfortunately I find that if I ever use the GUI tool (system-config-network) to configure network than the '$' there gets automatically escaped on save ! :)
The back tick form of shell command substitution is preserved though, so I can write: DHCP_HOSTNAME=`hostname -s`
For some strange reasone, when I do that, I get 'host name lookup failure' during `service network restart´ invocation, so in the end I resorted to using just: DHCP_HOSTNAME=`hostname` which seems to work properly until now, and now my router can see the computer names for its DHCP clients, which is a big step compared to seeing just the MAC address. :)
Thank you, Timothy Madden
