[gentoo-user] Need help with samba (Possibly OT)

[Michael Sullivan]

My personal workstation is a dual-boot setup with Gentoo and Windows XP.
A long time ago, I set up Samba on another computer on my network to
provide extra hard drive space to our Windows installations.  They used
to work, but we haven't used them in some time.  I tried to use it today
and it didn't work.  When I try to connect to the samba share from my
linux install, I get this:

michael@camille ~ $ smbclient //carter//home
Enter michael's password: 
Domain=[MYGROUP] OS=[Unix] Server=[Samba 3.4.6]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME
michael@camille ~ $ smbclient //carter//michael 
Enter michael's password: 
Domain=[MYGROUP] OS=[Unix] Server=[Samba 3.4.6]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME

(The host name is carter, and I didn't understand what the second part
should be.)
Also, I didn't know if "michael's password" meant my password on my
local box, my password on the remote box, or some password I set up for
Samba forever ago...

Here's my /etc/samba/smb.conf file:

carter samba # cat smb.conf
[global]
   workgroup = MYGROUP
   server string = Samba Server %v
   printcap name = cups
   load printers = yes
   printing = cups
   log file = /var/log/samba/log.%m
   max log size = 50
   hosts allow = 192.168.1. 127.
   map to guest = bad user
   security = user
   encrypt passwords = yes
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   dns proxy = no 

[homes]
   comment = Home Directories
   browseable = no
   writable = yes
   valid users = michael amy
   path = /samba

[printers]
   comment = All Printers
   path = /var/spool/samba
   browseable = no
   guest ok = no
   writable = no
   printable = yes

[print$]
   path = /var/lib/samba/printers
   browseable = yes
   read only = yes
   write list = @adm root
   guest ok = yes

[tmp]
   comment = Temporary file space
   path = /samba
   read only = no
   public = yes
   valid users = michael amy

I'm sure I've screwed something up somewhere, I'm just not sure what it
is.

If you're referring to the  //first/second syntax, then the first part  
is the computer name, the second part the share name.

The second / third option.

Each user on the Samba server has a password, but it isn't the same as  
their system password. Log on to the Samba server (i.e. `ssh carter`)  
and run smbpasswd (possibly `sudo smbpasswd -U michael`).

If it's been some time since this system was used, are you still using  
the 192.168.1.x subnet? If your ISP sent you a new router, you might  
now be on 192.168.0.x. IMO change this to:
    hosts allow = 192.168. 127.

Also run `smbtree` (works without a password).

I appreciate that Samba tends not to make any sense when you're  
inexperienced, but there ought to be lots of troubleshooting guides  
out there. Google "troubleshooting samba", follow through the steps  
suggested by 2 or 3 and report back & tell us what you've done.

I bought a brand new Linksys Wireless-N router a few months ago.  I
configure it to start addresses after 192.168.1.1 because that's what
we've always used, it's what all the computers on our LAN are set up
for, and I see no reason to change it.

Then I went to the Samba Checklist:
http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/diagnosis.html

1: Run testparm; already did that.
2: Ping test:

4:  carter ~ # nmblookup -B camille *

*I'm not sure what finding xorg.conf.new has to do with Samba, but it's
on the checklist...

And this is getting me nowhere very very quickly.

The shell replaces the * by files in your current directory. I do not know 
about nmblookup, but I gues you have to escape the *. That is, use '*' or 
\* instead.

What is this command looking for?

I've got a couple of new errors in the logs:

>From /var/log/samba/log.__ffff_192.168.1.3:
[2010/06/15 11:56:58,  0] lib/util_sock.c:1564(matchname)

What's with the ffff:192.168.1.3?  Camille's address IS 192.168.1.3, and
it seems to know that because it calls the host at the address
'camille'...
