Become Master Browser on unknown system???

[nedhedrick]

I am a new user of NAS4Free, and just getting started into CIFS setup. When I activate CIFS, it starts fine, and everything looks very normal...EXCEPT...

When I browse the NAS4Free diagnostic log, I see this entry:
nmbd[2744]: Samba name server NAS4FREE is now a local master browser for workgroup HOME on subnet 64.99.80.30

The IP address in the messge is not my network! A quick lookup indicates this IP address is for something called "HOVER". All of a sudden, I'm very concerned about privacy and security, which is the primary reason I opted for this solution.

Can anyone explain what is going on?

Thanks in advance!

You can enable / disable local master browser here: http://wiki.nas4free.org/doku.php?id=do ... _smb_samba

but you need to find in your network who is Hover, is not part of N4F code, so suspect from other PC in your local LAN.

Check your network over any security tester, such auditmypc.com

Thanks for the responses! I tried both "auditmypc" and grc tests and both showed no open ports.

It's very curious why NAS4Free would attempt to become a browse master on a "foreign" network. My local network is 192.168.0.xxx, but according to the log, NAS4Free is sending a request to become browse master on BOTH my local network and the IP address of 64.99.80.30. I'm really confused and concerned!

By the way, this is a new installation of 9.2.0.1 - Shigawire (revision 943), with nothing exotic...just a single ZFS pool with a single dataset, shared via CIFS/SMB.

My read of this log is that NAS4Free sends out a request to become master browser on TWO networks...one is my local network, and the other is somewhere completely different!

Or am i misinterpreting something?

[alexey123]

I see normall log on my nases - any another network.
Please send to forum your config.xml file ( delete password field ) and /var/etc/smb.conf file
