Re: [Samba] Browsing Problem
Hi! You could raise the oslevel to 255 for a try. If I am right, in the nmbd log you should see some lines regarding the loss of the local master role. Something like other machine believes it is master browser, but i am that, i can't recall it exactly. Wednesday, April 14, 2010, 6:16:09 PM, you wrote: Hi, I'm using samba 3.4.7 as a domain controller. Browsing network works fine, but sometimes ( about one week ), my PC can't browse more my Domain (no workstation saw). If I restart samba, all works again. I have read the samba doc on browsing http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/NetworkBrowsing.html My configuration seems ok, local master yes, preferred master yes, domain master yes, and an os level to 99. My samba has Wins support and my dhcp give him to workstations. Here is some command line that i have done to debug : nmblookup MYDOMAIN net lookup HOST net lookup master MYDOMAIN (answer is the samba server), but if I look /var/cache/samba/browse.dat or make smbclient -L, it's an other computer unreacheable which is master(after restart samba smbclient say me that it's samba my domain master). Why net lookup master and the other cmd don't tell me the same thing? is it the same thing? ( or lookup show me DMB and smbclient show LMB ?) Thanks for your help, i'm sorry for my english :-) Best regards! -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
[Samba] Wins name refresh requests getting ignored by samba, still running, accessible machines getting removed from browse with Timed out message
Hello all! I am using samba server at the company i work. Samba version is: 2:3.2.5-4lenny9 Some settings from my smb.conf: os level = 255 domain logons = no wins support = yes domain master = yes local master = yes preferred master = yes i have dhcp configured to send wins server address (this samba server's address) to all clients. After I (re)start samba within a minute or so all computer of our network appear on the browse list. Everything works as it should. The problem start after about 10-15 minutes, when machines start to disappear from the browse list. After setting loglevel to 10 to investingate things i found some interesting things: Anubis is the server with samba, Wladek is one of the many disappearing machines.
