Setting a DHCP option?   
I've done some digging over the past few days and found aa good amount of info about the dhcp.client process, but I 
haven't found anything that'll let me set a specific DHCP option. 

For example, what if I wanted to set the value of the DHCP option 12 (hostname) in my DHCP Discover packet in order to 
specify my hostname? Or use a different value for my Client Identifier (Option 61) than the one the dhcp.client process 
uses by default?

I know I can use the /etc/dhcp/dhcp-options file to request additional options from the server, but how do I *set* 
additional options?

Thanks,

Mike

RE: Setting a DHCP option?   
One advantage to having source posted:
http://community.qnx.com/integration/viewcvs/viewcvs.cgi/trunk/services/dhcp
.client/dhcp.client.use?root=core_networking&rev=1&system=exsy1001&view=mark
up

	I think that covers it...

RE: RE: Setting a DHCP option?   
If you've created a MyQNX account, you should be able to log in and "just
see it".  If you haven't logged in, the collabnet interface is a bit bizarre
in that what you have to do is go to the repository

http://community.qnx.com/sf/scm/do/listRepositories/projects.networking/scm

Clock on the "Core Networking" button and then click on "view Commits" (left
side).  You can then click on the "Browse repository" button.

I would have thought that the link that I gave you would have taken you
straight to the use message, but, then again, I'm logged in...

	Robert.

Re: RE: RE: Setting a DHCP option?   
OK, got it, thanks... 

I see that you guys have added the -D option for the client ID... but what if I wanted to set the Class-ID (option 60) 
as well? User Class Information (Option 77)??

You guys might want to consider adding a way to hook ANY custom DHCP option into the client application... 

Thanks for the info though. Very helpful!

That feature already exits since the source is available.  You can add
whatever you want to it.
