Samba problem

[decrepit]

I have 2 computers on my local network, percy has the internet connection and last week I installed 10.04 on it. charlie has an old version of centos.

percy and charlie have been talking to each other for many years with different flavours of linux.

I set up samba on percy and it worked as always, when "network" is selected
percy and charlie come up and both computers can be browsed.

I then followed the instructions for masquerading, and charlie could then use the internet.

But, that killed samba, figured that the firewall was to blame, sure enough turn firewall off and samba was back to normal.
So after some research I added this to /etc/rc.local

iptables -A INPUT -p ALL -i eth1 -s 10.0.1.0/30 -j ACCEPT
iptables -A INPUT -p ALL -i eth1 -d 10.0.1.255 -j ACCEPT

Now I've got half samba back, percy can see charlie but charlie can't see percy, and strangely when selecting "network" from percy only charlie appears.
But from percy if I

michael@Percy:~$ nautilus smb://10.0.1.1
michael@Percy:~$ nautilus smb://10.0.1.2

I get both sets of shares, however if I do the same from charlie I get a message saying "sorry couldn't display 10.0.1.1"

I had a look at smb.conf and at the bottom there was these lines.

[michael]
	comment = mike's home
	path = /home/michael

;	browseable = yes
	guest ok = yes
	available = no
	writeable = yes

So I changed the "no" to "yes"
but that hasn't made any difference.

Any ideas, anybody?

I've been thinking about this, and I don't think this has anything to do with the firewall.
If I turn the firewall off, the problem is still there, "percy" does not appear on either computer.

I had 2 goes at installing samba, the first time through synaptic package manager, didn't install the gui, I had a go at set up with smb.conf but when I went to System > Preferences > Personal File Sharing, I got an error message saying "This feature cannot be enabled because the required packages are not installed"

So I did an "apt get samba" from the command line, that installed another 2 packages, 1 of them the gui.
That may have been when the problem started.

So should this computer's name appear in the gui?

There's a line labeled "description" under "workgroup" that has

%h server (Samba, Ubuntu)

in it. Is this where "percy" should be?

I'd be looking at the routes set on each machine, but especially percy.
I suspect that all traffic is being routed to the internet (I use route print in a terminal window, being 'old school').
Also a simple ping test from charlie to percy (using IP address?) might be interesting.

Thanks Derek,

I tried "route print" but that didn't work, came up with a list of options I didn't understand.

And ping works both ways, charlie can see percy and percy can see charlie.

Samba also works fine from percy, in that it has full access to charlie's shares. But unlike before, "percy" doesn't show up on either network.

[dandnsmith]

Sorry, gave the wrong version there - should just be route (the route print is the Windows version).

Next, after the ping, I'd look in the log files for smbd and nmbd, having first established that the processes are running, especially on percy (where the trouble is centred).

Thanks Derek,
OK that did it.

Doesn't mean much to me I'm afraid. except the 2nd line, that's my lan.

Not sure how to check if smb and nmb are running.
In fedora, you can check every service from a gui and turn it on or off.
But I can't find that in ubuntu. The closest is "start up applications", but that doesn't mention either of those.

But if they weren't running, would I be able to browse charlie's shares from percy?

[decrepit]

Just checked with "system monitor", doesn't show either of them running.
I tried double clicking on "windows network" and with charlie turned off, I just get,
"unable to mount location. Failed to retrieve share list from server"

And still system monitor shows no activity from smb or nmb

Also if I try to use "system" > preferences > personal file sharing, it tells me I don't have the right software installed.
Could this be another indication samba isn't running?

How do I make sure it is?

[decrepit]

OK, found the command on another thread.

michael@Percy:~$ sudo service smbd start
start: Job is already running: smbd
michael@Percy:~$ sudo service nmbd start
start: Job is already running: nmbd

So looks like they are both running.

[dandnsmith]

You may get some mileage out of
smbclient -L machinename putting in percy or charlie
also
nmblookup (check man pages?)

samba.org/docs contains links to sources of testing docs.

The route printout looked OK to me - not really surprised after pings reported working both ways.

In /var/log you should find lots of logs - including those from smbd and nmbd. Might be something there.

Thanks Derek,
Had a quick look thru the logs, this looks significant, from the log.nmbd

So do I need to set master browser in smb.conf?
