annoying domain.local issue

[Valent Turkovic]

Hi,
I have trouble accessing local services inside my company from my
Fedora desktop.

We have samba webserver at samba.domain.local and when I try to open
it via Nautilus it fails. I also have Windows XP running in VirtualBox
and Windows open this samba share with no issue.

Also pinging samba.domain.local works form Windows in VirtualBox but
doesn't work from Fedora.
There is also a web server at web.domain.local that also works under
Windows but doesn't work under Fedora 10. If I remember correctly this
all worked under Fedora 6.

Do you have any issues when domain ends with dot local (.local) ?

How can I troubleshoot this more and fix it?

Both Fedora and Windows use the same DNS and same default gateway.

Thank you in advance,
Valent.

any domain can be resolved if you have it in /etc/resolve
type in the nameserver there and try again.. should work

And does that DNS server have an answer for queries to that domain name?
If it does, does it have the right answer?

How domains are resolved is configured in a few places.
The /etc/nsswitch.conf has a hosts section which lists the places to
look up through, in sequence.  Mine has the following in it:

#hosts:     db files nisplus nis dns
hosts:      files dns

("files" being the /etc/hosts file, "dns" being a DHS server.)

Putting a custom entry into your hosts file, for your .local addresses,
ain't gonna help you if it consults a DNS server, first, which says
something different about .local.

That's used for networking, in general.  SMB work independently, it can
also use an lmhosts file (inside the /etc/samba/ directory), or as a
WINS server (an option inside the smb.conf file), as well as DNS.

I'd suggest posting your hosts, nsswitch.conf, resolv.conf and smb.conf
files for others to see what you're doing, rather than guess.  Also the
outputs from running nslookup and dig with your problem domain name.

i.e. dig samba.domain.local
     nslookup samba.domain.local

If you're bodging up faux domain names, you might have to fiddle quite a
few things to get it to work.  I found it easier to run my own domain
name server, with records for local domain names, and have all my local
computers use my domain name server.

ping doesn't work from Fedora;

# ping web.iskon.local
ping: unknown host web.iskon.local

# ping samba.iskon.local
ping: unknown host web.iskon.local

When I enter in my hosts file this line:
10.0.0.18    web.domain.local

then I can ping the web server from my Fedora laptop... any ideas?

The same issue is also with Ubuntu 9.04
I can't ping web.domain.local but I get IP via nslookup and I can ping
the IP address.

Something is fishy, and I guess I didn't configure it properly but I
can't seam to see what I'm doing wrong.

I looked at Windows ipconfig /all output and this is what I see:

C:\Documents and Settings\Valent>ipconfig /all

Do I need to configure dns suffix on Fedora also, why and how?

Let's go back to basics.
You can to to System/Administration/Network, and edit your connection. 
You can either enter the DNS information in the DNS tab or in the 
General Tab, check Automatically Obtain DNS information... Either should 
do it.

after some troubleshoting with tcpdump I saw that no reqests were send
when I used .local domains! And after some more googling I stumbeled
upon post [1] saying that avahi is the problem and that it graps and
.local queries!

After shuting down avahi service everything started working!

Thank you all for your great effort in helping me!

if you are not using the dns on your fedora you would need to
configure fedora to use another dns server which can be done in
/etc/resolv.conf
the host file is to identify the ip and local host of your computer
and dns is for other machines on the network

That would appear to suggest that you don't have anything to tell your
machine how to use those addresses.  No hosts file entries, no DNS
records.  Unless, you do have a DNS server with that information, but
you're querying another one that doesn't.

The important line from that is this:

hosts:      files mdns4_minimal [NOTFOUND=return] dns

Which, if I've understood the bit in the middle does:
1. "files" first look in /etc/hosts, then try
2. "mdns4_minimal", and if no answer is found, abort
without getting around to querying a "DNS" server.

This doesn't seem sensible to me.

Unless you have something special, usually all that's needed is:

hosts:      files dns

If mdns4... is doing something useful for you, perhaps try just removing
the notfound=return section.

>  hosts :
>  http://fpaste.org/paste/10361 
Pretty much a normal file.  It defines local loopback addresses (how the
machine refers to itself, the computer equivalent of "myself").  It's
expected that something else will resolve other addresses, such as your
DNS server.

>  resolv.conf :

Again, looking normal, presuming that there are DNS servers you can
query at 10.0.0.6 and 10.0.0.7.

This indicates that a DNS server at 10.0.0.6 says that web.domain.local
has a numerical IP address of 10.0.0.18.

Same as above, with the dig query.

And again.

That could be a firewall issue, but you'd not expect a comment about
unknown host, if it simply couldn't ping something it had an address
for.

Check if both your domain servers can answer that query.  Use the dig
command, with the address for each name server.

e.g. dig web.domain.local @10.0.0.6
     and, dig web.domain.local @10.0.0.7

If they both get answers like above, then both domain name servers are
working.

Windows can muddy the waters, as it can try other things to try and
resolve names, as well.  Windows networking (SMB) for instance can find
machines without DNS or hostnames (essentially asking for a machine by
name, and hoping that it answers for itself, or another machine on the
SMB network gives it the address for it).

See if the comment I made about modifying your /etc/nsswitch.conf file
makes any difference.  Everything else, configuration-wise, seems
normal.
