Actaully /etc/resolv.conf is being set up with nameservers ( DNS ) provided
by the DHCP server. It is made automatically after dhcp.client has been
started.
Although when I " ping kvardin" or somebody else who I know it is not
resolved --"Unknown host ".
So what is the catch ?!?!
Here is how I start dhcp.client :
#dhcp.client -ien1 -hkvardin&
After that I am able to ping absolute addresses, I am also browsing,
telneting,…, but not name resolving !!
Regards !

DNS and DHCP server are two disctint entity. When a new machine is
detected by the DHCP server, the entries of the new machine isn’t
automaticaly added in the DNS. Some DNS server (Microsft)
can deal with this but most don’t. Even the Microsoft one needs
some fiddling, I’m told.

Do a getconf _CS_RESOLVE and see if the name server info is there - my bet
is that it isn’t. Instead of using dhcp.client manually, what happens if
you use the GUI tool to configure your network via DHCP
(/usr/photon/bin/phlip - login as root to run (su -)).

has been started.
It doesn’t make any difference, the DNS doesn’t learn about the new machine.
If you go look at the DNS database I’m sure you’ll see the entry for the new
machine isn’t there.
Thanks for your commitment guys,
Here is the result of getconf _CS_RESOLVE:
nameserver_207.181.101.4
nameserver_207.181.101.5
nameserver_10.0.0.1
The same is also written automatically into /etc/resolv.conf after
dhcp.client returns.
I am expecting the answer of our sysadmin regarding DHCP server <-> DNS
cooperation as it seems this might be the explanation.
Regarding the docs dhcp.client is setting enviroment vars like IPADDRESS,
NAMESERVER1, NAMESERVER2, HOSTNAME … and submits them to /etc/dhcp/dhcp-up
script if such exists. I created such a script just to echo for myself the
results of dhcp.client, but it is not even called form dhcp.client as
expected. I think this scripts is very usefull at least to detect some
anomalies into DHCP server <-> DNS.

Well,
The problem explanation ( as I was told by our sysadmin) is that our DHCP
server does not log hostnames into the local name server, actually it is
used WINS!
