Re: [BackupPC-users] Communicating with a windows laptop on my workgroup
Chris, Thanks for the additional help on this. I was able to make the changes and set my laptop to look at my Linux box as a WINS server. So now when I perform the following command from the command line I get the following: nmblookup -U 192.168.15.2 -R laptop1 querying laptop1 on 192.168.15.2 192.168.15.155 laptop100 That to me means it works and it's finding the IP address for my laptop :) However, there are still issues. When I try and perform a backup of laptop1 from within the web interface I get the following message: Error: Can't find IP address for laptop1 laptop1 is a DHCP host, and I don't know its IP address. I checked the netbios name of 192.168.15.155, and found that that machine is not laptop1. Until I see laptop1 at a particular DHCP address, you can only start this request from the client machine itself.

I also updated the config file for laptop1 such that NmbLookupFindHostCmd is set to: $nmbLookupPath -R -U 192.168.15.2 $host Feel like I am getting closer to getting this working now that I can at least get success from the nmblookup command. ___ Dave Williams Check out our WebOS mobile phone app for the Palm Pre and Pixi: Golf Caddie by DTW-Consulting, Inc. -Original Message- From: Chris Bennett [mailto:ch...@ceegeebee.com] Sent: Thursday, March 18, 2010 7:07 PM To: dwilli...@dtw-consulting.com; General list for user discussion, questions and support Subject: Re: [BackupPC-users] Communicating with a windows laptop on my workgroup Hi there, No, it doesn't make sense. What you want (and need) is a master browser, which (on a workgroup, not a Windows domain) is elected from computers on the segment. N.B.: if you're not on the same segment and don't have a domain controller, you can't browse or use nmblookup. WINS was created to work around this, and may help you in this case as well. Name resolution in SMB/AD uses three methods: - broadcast - WINS - DNS The thread has mostly been about getting a master browser working, but if the two BackupPC client nodes are on the same segement, broadcast resolution should work. The exception might be if your client is not responding to Netbios broadcast name queries (UDP 137). So WINS can provide you a central name resolution service (WINS server) which can respond to name queries on behalf of clients. The caveat being the clients need to know to register their name with a WINS server. WINS also solves the name resolution between segments problem. DHCP can dish out the WINS server setting (ISC dhcp name it 'netbios-name-servers'), but since you're statically allocating an IP address, you'll need to manually configure the setting. I found http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/rzahl/rzahlcfgpc winsxp.htm which describes how to do it for Windows XP. The samba server requires the option wins support = yes Now when you're client boots up, it'll register it's name with the WINS server. nbmlookup accepts a -R and -U option. From the manpage: -U unicast address Do a unicast query to the specified address or host unicast address. This option (along with the -R option) is needed to query a WINS server. -R Set the recursion desired bit in the packet to do a recursive lookup. This is used when sending a name query to a machine running a WINS server and the user wishes to query the names in the WINS server. If this bit is unset the normal (broadcast responding) NetBIOS processing code on a machine is used instead. See RFC1001, RFC1002 for details. Test first to ensure nmblookup returns the expected result, and then update backuppc to use the above options when calling nmblookup. The third resolution method (DNS) is just that: given a bareware name, append a suffix to the name and send a query to the configured DNS server. AD uses this now to replace broadcast and WINS resolution, coupled with dynamic DNS for clients to register their name to the DNS server. So hopefully that can help you to configure things the way you'd like to - personally, the neatest solution is to setup a DNS server, and configure your a DNS record for your desktop since it's statically assigned, but all methods above should work they way their advertised to work :) Regards, Chris Bennett cgb No virus found in this incoming message.

Re: [BackupPC-users] Communicating with a windows laptop on my workgroup
I posted this to a Linux forum but also wanted to post it here since this is also relates to backuppc. Only peripherally, in the sense that if you're using smb and smb doesn't work, backuppc won't work. I did post something a while back and some mentioned about modifying Samba so that it became a local master. Anyway, I made the changes to my smb.conf file with the following: local master = yes preferred master = yes wins support = yes That said, I still cannot seem to perform a nmblookup on a windows laptop that is connected to my network that has a dynamic IP address L I'm not entirely sure why you'd want to use NMB rather than DNS; then again, I don't recommend SMB since rsync is available. I have just noticed something in my syslog, which I believe is related to a change in my Samba setup. I am using Backuppc to perform backups on my linux server and I was (and still am) having a problem in that I wasn't able to back up any machine that had a dynamic IP address, namely my laptop. Does it actually resolve via DNS? It seems that nmblookup will not resolve the ip address from any machines on my network. Really not sure what the problem is since I have very little experience with this. Also, I don't remember what change I made to the samba configuration (I had a look but nothing jumped out) other than it had to do with enforcing Samba to act as a Domain Master if that makes sense. No, it doesn't make sense. What you want (and need) is a master browser, which (on a workgroup, not a Windows domain) is elected from computers on the segment. N.B.: if you're not on the same segment and don't have a domain controller, you can't browse or use nmblookup. The errors I am getting in my syslog are as follows: nmbd[4123]: find_domain_master_name_query_fail: nmbd[4123]: Unable to find the Domain Master Browser name XX1b for the workgroup X. nmbd[4123]: Unable to sync browse lists in this workgroup. That's normal. The local master browser is looking for a domain master browser. Which you apparently don't have. This is indicating that for whatever reason, samba is not functioning as the LMB. There may be better clues when it starts up, since typically that's when the elections are held. In your log.nmbd, you should see this sort of thing: become_domain_master_browser_bcast: Attempting to become domain master browser on workgroup X on subnet 10.168.0.1 If you're not seeing this, then something's funny with your smb.conf. I'd really appreciate any help that would allow me to be able to use nmblookup (which is what backuppc uses to resolve client names to an IP address) and work out just what I did to samba. Can you actually browse any windows shares at all? If I try and do a nmblookup for a client I get the following error message: nmblookup laptop1 querying laptop1 on 192.168.15.255 name_query failed to find name laptop1 Without a local master browser, this is to be expected.

Re: [BackupPC-users] Communicating with a windows laptop on my workgroup
I've tried to clear out some of the ancillary stuff to keep this readable. I am by no means an expert in this area at all, and I am open to looking at other options. I know that I had the smb method working a while back on a fixed IP address windows machine. The last time I posted on here with this issue, albeit with less information, I was asked to make the changes to Samba that I indicated above. I don't pretend to always understand the ins and outs, just as long as I can get it working J I'd recommend rsync as a matter of course, which requires that your network be working, but not all the NetBIOS/SMB stuff that rides on top of it. Does it actually resolve via DNS? This is a home network so to be honest, I wouldn't even know how to go about testing this. My laptop is associate to a Workgroup and my Linux server has a static IP address within the 192.168.15.x range. I can ping the laptop by ip address but I am not sure what it's normal address would be. For example, would it be laptop1.workgroup.com ? Probably not. Somewhere on your network you've got a DHCP server that's giving your laptop an IP address, and there's probably a DNS server that's either being updated directly by your laptop (Windows does that) or by your DHCP server. At any rate, to find out, open a command window on your Windows box and type: ipconfig Which should yield a connection-specific DNS suffix. Workgroups/WINS is -quite- different, and entirely unrelated.

I'd really appreciate any help that would allow me to be able to use nmblookup (which is what backuppc uses to resolve client names to an IP address) and work out just what I did to samba. This is fairly unusual -- it's showing that your samba box is electing to be the local master browser, yet nmblookup is unable to find it. Usually when this happens it's because the workgroup name doesn't match, but if I'm reading the above correctly, both are WORKGROUP, which is the default. I'd recommend boosting the debuglevel on nmblookup to get more detail on what's going wrong. (Setting it to 1 should probably suffice.) Can you actually browse any windows shares at all?

Re: [BackupPC-users] Communicating with a windows laptop on my workgroup
Hi there, No, it doesn't make sense. What you want (and need) is a master browser, which (on a workgroup, not a Windows domain) is elected from computers on the segment. N.B.: if you're not on the same segment and don't have a domain controller, you can't browse or use nmblookup. WINS was created to work around this, and may help you in this case as well. Name resolution in SMB/AD uses three methods: - broadcast - WINS - DNS The thread has mostly been about getting a master browser working, but if the two BackupPC client nodes are on the same segement, broadcast resolution should work. The exception might be if your client is not responding to Netbios broadcast name queries (UDP 137). So WINS can provide you a central name resolution service (WINS server) which can respond to name queries on behalf of clients. The caveat being the clients need to know to register their name with a WINS server. WINS also solves the name resolution between segments problem. DHCP can dish out the WINS server setting (ISC dhcp name it 'netbios-name-servers'), but since you're statically allocating an IP address, you'll need to manually configure the setting. I found http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/rzahl/rzahlcfgpcwinsxp.htm which describes how to do it for Windows XP. The samba server requires the option wins support = yes Now when you're client boots up, it'll register it's name with the WINS server. nbmlookup accepts a -R and -U option. From the manpage: -U unicast address Do a unicast query to the specified address or host unicast address. This option (along with the -R option) is needed to query a WINS server. -R Set the recursion desired bit in the packet to do a recursive lookup. This is used when sending a name query to a machine running a WINS server and the user wishes to query the names in the WINS server. If this bit is unset the normal (broadcast responding) NetBIOS processing code on a machine is used instead. See RFC1001, RFC1002 for details. Test first to ensure nmblookup returns the expected result, and then update backuppc to use the above options when calling nmblookup. The third resolution method (DNS) is just that: given a bareware name, append a suffix to the name and send a query to the configured DNS server. AD uses this now to replace broadcast and WINS resolution, coupled with dynamic DNS for clients to register their name to the DNS server. So hopefully that can help you to configure things the way you'd like to - personally, the neatest solution is to setup a DNS server, and configure your a DNS record for your desktop since it's statically assigned, but all methods above should work they way their advertised to work :) Regards, Chris Bennett cgb -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
