[Samba] LAN Browsing shows IP Addresses instead of Computer Names.

I'm trying to figure out how I can have my lan browser display computer 
names instead of IP Addresses.  I think the ip addresses are generated by my 
router since if I add a new computer, the ip addresses will be different for 
each computer.  anyway let me give you the specs first.  Running Samba 
2.2.8a-1 on Red Hat 7.3.  I have not set up WINS or DNS at all.  I have set 
up lisarc to use nmblookup.  I'm assuming that my network is using 
broadcasting to get computers in my LAN since i have not set up any computer 
names in hosts or lmhosts.  The current set up works right now in that 
computers come up and can be browsed independant of the ip addresses 
assigned to the computers.  ie. if computer Tron is up on the network, and 
then I boot up Sark, Sark will show up at the first next broadcast.  but the 
computers show up in konqueror as ip addresses, not as Tron and Sark.  My 
very old first setup attempt had me manually adding ip addresses and names 
manually in the /etc/hosts file.  but that would mess up the lan browsing if 
another new computer was added to the network.  So if Sark is 192.168.0.2 
and Tron is 192.168.0.3 and let's say my brother brings his laptop and i put
his laptop on the network, the ip addresses on the network will change to 
something like Sark = 192.168.0.3, Tron = 192.168.0.2 and my brother's 
laptop maybe something like Bros_comp = 192.168.0.4.  but the /etc/hosts 
file will have the old assignments which really messes up the browsing part. 
  Anyway right now i think i have it set up almost right since i can browse 
the network and the computers on the network will be found no matter the 
time they are actually booted up, but ip addresses in the lan browsing isn't
very useful and I would like to see the computer names displayed in the lan 
browsing in konqueror.  thank you for your patience, time, and any help you 
can provide.

Sincerely,
Vince =)

[Samba] LAN Browsing shows IP Addresses instead of Computer Names.

I am no expert and am certainly rusty on this sort of question. Just some
ideas. I do not know if the suggestions below are really what you
need. However, how do you think that samba is supposed to do reverse
lookups to find the name corresponding to an ip number?

1. Have you walked through DIAGNOSIS.txt?

2. What is this router you have that keeps changing ip addresses? Very
inconvenient. It is not hard to set up a dhcp server on a linux box. The
nice part is that you can ensure that the  same ip number is given
every time to the same computer, using the identifying number on the network
card.

3. If you do #2, then you can use [lm]hosts files on both the linux and windows
boxes to associate names and ip addresses.

4. The easiest thing might be to install a wins server. This just involves
adding a few lines to smb.conf on one linux box. Here is what I have
in mine:

        name resolve order = lmhosts wins bcast host
        netbios name = JHAMMER6
        os level = 100
        preferred master = True
        domain master = True
        wins support = Yes    

This makes this machine the wins server. Point your other machines,
to this one. This requires a wins server = parameter in the linux boxes and
you can muck around with the menus in windows to point to the wins server.

5. Maybe you have a bad name resolve order parameter? The meaning of the
options above is:
 lmhosts = /etc/hosts file 
 wins    = wins server
 bcast   = broadcast
 host    = DNS lookup
Do you have the bcast option in your smb.conf file? 

6. If you want to spend many happy hours, you might consider setting up a
DNS server, provided you have set up a DHCP server to ensure the same ip's
are given each time to the same computers.

7. Can you tell your router to always give the same number to each of
your computers?

[Samba] LAN Browsing shows IP Addresses instead of Computer Names.

Thanks for the reply.  lemme go through your points and suggestions one by 
one. =)

1. I don't know where Diagnosis.txt is.  whereis and locate come up empty 
and I've done a file search in /etc and /usr.

2. Interested in this.  Any good places your recommend for this information? 
  That is, easy for a complete nimrod like me?

3. See #2

4. Do I really need to set up a WINS server?  Most of the time the network 
is just a windows 98 computer and this Linux computer.  although there maybe 
times, since the windows computer is a dual boot windows 98/windows NT 4.0, 
that I boot the windows computer into NT.  the Linux computer is also a dual 
boot of windows ME/ redhat 7.3.  I think there maybe some kind of conflict, 
if I've read things right, between the Linux computer and the other computer
if booted into windows NT.  Any clarification on that would be greatly 
appreciated.

5. this is the resolve order from SWAT: lmhost host wins bcast

6. again see #2, if this is what a really have to do. =)

7. I could, but mucking about the router internally gives me the 
heebie-jeebies.  And basically, the if all the computers are booted into 
windows, the network works fine with the router config as is.  I don't 
understand why this would change for Linux.  but, I'm a newbie nimrod with 
Linux, so any explainations would be great.

Here's an nmblookup query.  it seems to me that the ipaddress and the 
NetBIOS name are returned.

[vjong@Tron vjong]$ nmblookup han
querying han on 192.168.0.255
192.168.0.4 han<00>

Yes, this is one case where I would love to have Linux work like Windows and 
I think I'm close since computers that come up on the network are found and 
browseable, it's just that their computer names aren't being shown in 
Konqueror just the IP addresses.  I'm gonna try to add the computer names in
/etc/lisarc and see if this works.  Thanks again for the suggestions and 
help. =)

Sincerely,
Vince

That's your problem, reverse lookups need to work, either via DNS or
nss_wins (apparently it works without a WINS server, in which case it
used broadcasts).

I don't know is RH ships with a working nss_wins, if they do, it should
work by adding "wins" to the hosts line of your /etc/nsswitch.conf
file.

BTW, setting up working reverse DNS would be a better solution, for
services that don't use get*ent, but direct DNS lookups.

[Samba] LAN Browsing shows IP Addresses instead of Computer Names.

hmm.... looks like I'm gonna do it how I did it before and just add the ip 
address and computer name pairs in /etc/hosts and have my router assign 
static ip addresses.  Thanks for all the suggestions.  you guys are great.

Although, I'd still like to know how MS Network Neighborhood does it.  I 
don't want to set up my linux box as a server of any type since it's a 
laptop and is often taken out of the network when I travel.  I mean let's 
just say for the sake of argument, that i've got a linux machine and a 
windows 98SE computer.  How does Network Neighborhood get the computer name 
of my linux machine?  Since I'm know I didn't set up the windows
computer
with any DNS or WINS server.  but i'll go with what works for both. Any 
thoughts, please feel free to post 'em. =)

Sincerely,
Vince
