Folks, Many of you have seen my network traffic as I struggle to set up a small 2-subnet Samba-served LAN, and many of you have offered help in that endeavor, for which I thank you. Now, however, I'm confused. Last night, when I shut down to go to bed (I have, unfortunately, a day job, and my employer insists that I work it occasionally), I had no connection between my Win2k PC, or between my WinXP laptop, and my SUSE 9.3 server (running Samba as a PDC, and dhcp and dns servers). This evening, when I booted everything up (server first, then PC and laptop, as always), without doing anything else, there was my server, in both my PC's and laptop's Network Neighborhood windows, together with the laptop in the PC's window and the PC in the laptop's window, and I could connect to the server and begin working some share problems I'm having (I could get into my home share, so I know the connection was more than just a pretty picture in the window). Then I had occasion to reboot my PC (oddly, Firefox hung on an entirely unrelated task). When the PC came back up, there was no connection at all--the PC couldn't even see itself in its Network Neighborhood window. At about the same time, my laptop had lost its connection to the server, even though I had been doing nothing on it--it had even gone to sleep in power save mode--and also could not even see itself in its Network Neighborhood window when I woke it back up (although I don't think this was caused by the PC reboot). Now, 2 hours later, both the laptop and the PC can see themselves in their respective Network Neighborhood windows, but they can see nothing else--in particular, they cannot see the Samba server. What's going on? Why is this so inconsistent, and what can I do about it? ASCII art on my LAN is just below; all addresses are 192.168. .3.9 ----------.3.1----samba (PDC/dns/dhcp-----.2.2---------.2.9 (WinXP (NIC) | (NIC) (Win2k laptop) (NIC).1.2 PC) | | Linksys .1.1 | Internet Thanks for your help.

Hi Eric; I had a small consulting company a couple of years ago and we had a config very similar to yours. We had inconsistent issues with visibility between machines. We eventually moved to a linux firewall solution (www.astaro.com) which is downloadable and a free home/small business license is available. Once we configured astaro in place of the linksys box all the connectivity issues behind the firewall went away for good. I use it at home today, its a beast to configure - however its worth it, once configured it basically needs zero maintenance. Hope this is some help...

Thanks, I'll look at this. However, I really want to understand what's going on with this set up, too--it should work. The inconsistency that bother me the most is the inconsistent visibility between the Windows machines and the Samba server. Or maybe not so inconsistent; I've only gotten to the Samba server once in the month I've been fighting with this problem.

Eric:
How are your Windows PCs configured wrt the network stack?
Are they configured so that the ONLY external protocol is TCP/IP? (No
NETBEUI, etc. on the Windows machines.)
Since you are using a class C non-routable IP address (192.168.x.x), are
the netmasks for the windows client set to 255.255.0.0 (the default is
255.255.255.0)? Is the Linksys (I presume a WRT54G) set for the same
netmask? (You might consider using a different network, eg 10.0.x.x, as
it has a different netmask.)
You need to be more specific about the local machine configuration.

How did you determine that 192.168.x.x would have a different netmask than 10.0.x.x ? That statement does not make any sense. Look at the diagram above. A netmask of 255.255.255.0 is appropriate for his needs. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998

How do I check?

NETBEUI, et al., were explicitly uninstalled from my PC a long time ago. The only external protocol installed is TCP/IP. Eric Hines There is no nonsense so errant that it cannot be made the creed of the vast majority by adequate governmental action. --Bertrand Russell

The Linksys sits on the edge of my LAN and fronts for it to the Internet. Everything that's happening on the LAN, including the on-again-off-again connection to my Samba server (which, by the way, is up today, but since I don't know why it's so unreliable, I don't consider this problem solved), is happening behind the Linksys.

Then I misread the diagram, sorry. Start from the top again please - You have a linux samba server - please post the smb.conf file. Also - are you using a wins server? I had some odd connection problems (don't recall the details, it was a while back) until I set one up - on the samba server, as it happens. You have windows workstations (Pro or home? Networks in XP home is severly broken.) that are connecting to the samba server intermittantly. Can you post the samba log from a session when the connect fails, and when the connect works? Have I got the basics straight?
