Actually, as I was saying, I have a sub-net of 8 computers and 1 router
(and also one switch if you want).
The router is stubborn enough to make sure that no incoming connections
or outside traffic get to the sub-net (except on the forwarded ports),
even if I would actually like to be able to route traffic from the
company LAN (where my work computer resides) to the machines in the sub-net.
In this sub-net I *could* get DHCP for IP allocation and WINS for name
resolution work together. There was nothing special to do than:
- start smb and winbind (no NetworkManager...)
- include 'wins' in the 'hosts: ' line in /etc/nssswitch.conf
- maybe add a DHCP_HOSTNAME=`hostname` line to
/etc/sysconfig/network-scripts/ifcfg-eth0 script, for my router
to see the computer names.
There was no need to prevent DHCP client from retrieving DNS information.
In this way, I need no dedicated machine for DNS, DHCP or WINS, and I
can use all 8 machines for testing our product. Our test procedure
specifies that the machines involved should be restarted just before
tests begin. I believe that would be a problem if want to pick one of
them as the DHCP/DNS/WINS server ...
So I want to repeat the procedure for two other machines in the
(outside) company LAN, where I had the same name resolving problems in
the past, on a different project, and which where still in use. Much to
my surprise, the same configuration did not work there, in a larger and
different network (the company LAN), with or without the enabling DHCP
to also retrieve the DNS information. It is here on these two machines
where I reverted to stati IP instead of DHCP.
I do not know any special difference between the two computers (I run
yum update on both), or what causes my configuration to work in one
network, but not in the other ... Any suggestions are welcome !
Thank you,
Timothy Madden
