make computer name show in wifi (Solved)

[Grandpa]

My Parks wifi likes for your computer name to show on their routers.  I have found my computer name.  I opened a terminal and typed "gksudo gedit /etc/hostname".  that said my computer name was "grandpa@localhost".  how do I make that show on the Parks routers when I sign on?  Thanks for any help.

Texstar's instructions are here. Works for me.

Wait a minute. Misunderstood your post. Is Parks router a brand name?

I read it the same way as you djohnston. I think Tex's instructions will work.

I will reply first then read Tex post.  The Parks router is Linksys WRT54g v2 with DD-WRT firmware installed.  I am also using a like router with the same firmware installed as a Client Bridge.  The Park uses a list of known computer names to know if someone is online who has not paid.  My computer name shows blank.  That is not a big deal as I am the one who does the checking.  But I would like to show up like everyone else.  My windows computer does.

Try adding the following to your /etc/sysconfig/network file

DHCP_HOSTNAME=<yourhostname>

@YouCanToo
Not sure if this is what you mean.  My file now reads

HOSTNAME=localhost . localdomain
NETWORKING=yes
CRDA_DOMAIN=US
DHCP HOSTNAME=LINUX LAPTOP

If that is what you mean it did not work.  But thanks for the reply

It probably didn't work 'cuz the line in red (above) isn't correct. It should be DHCP_HOSTNAME, and not as you have it with DHCP HOSTNAME. Notice the missing underscore character.

[Grandpa]

That did not work either.
Since I sign on as a DHCP Client I have also tried
DHCPClient_HOSTNAME=LINUX LAPTOP
DHCP Client_HOSTNAME=LINUX LAPTOP

None of which worked.
But thanks for the reply!

Grampa, Paul was correct there should be a underscore in the DHCP_HOSTNAME

also you show your  HOSTNAME=localhost . localdomain  this is not correct there should be no spaces in the localhost.localdomain part

[Grandpa]

That is a typo here.  In the file there is no spaces.
Thanks again

Did you get this one sorted out??

[Grandpa]

Yes I did.  I don't know what I was doing wrong before.  But here is what I added to the /etc/sysconfig/network.  The line reads "DHCP_HOSTNAME=grandpalinux".  I will change this to solved.  Thanks to all who replied.

Maybe the space in "LINUX LAPTOP"  upset it ....

I just read on the internet the the DHCP_HOSTNAME does not like names with spaces in it. It recommended changing all space to either a "-" or "_".  It looks like you stumbled on to the solution to your problem.
