Btsync 1.2.91 On Ubuntu 12.04 Does Not Listen On Port 3838

I have setup BTSync between Ubuntu and Windows 7 machines (LAN only) and they cannot see each other. All worked just fine with 1.2.82. Strange thing is that the Windows version (1.2.91) listens on port 3838, but the matching version of BTSync on Ubuntu does not open this port. All the same firewall settings as before and I even tried disabling firewalls altogether with no difference. There are no errors in the debug log.

 

What am I doing wrong?

 

1.2.82:

sudo netstat -npl |grep btsync
tcp        0      0 0.0.0.0:8888            0.0.0.0:*               LISTEN      1415/btsync-daemon

udp        0      0 0.0.0.0:3838            0.0.0.0:*                           1415/btsync-daemon

netstat -npl |grep btsync

Hi fantom,

 

Could you please try to perform couple of commands on your windows and linux machines when BTSync is running?

 

Windows command:

netsh interface ip show joins

 

Linux command:

netstat -gn

 

and provide their output?

Thanks!

I have reverted BTSync on Ubuntu 12.04 to 1.2.82. Not sure if that matters, I have disabled IPv6 in kernel with "ipv6.disable=1"

 

Ubuntu 12.04 (1.2.82):

sudo netstat -gn
IPv6/IPv4 Group Memberships
Interface       RefCnt Group
--------------- ------ ---------------------
lo              1      224.0.0.1
eth1            2      239.192.0.0
eth1            1      224.0.0.251
eth1            1      224.0.0.1
 

Windows 7 (1.2.91)

netsh interface ip show joins
 
Interface 1: Loopback Pseudo-Interface 1
 
Scope       References  Last  Address
----------  ----------  ----  ---------------------------------
0                    1  Yes   239.255.255.250

I got another Ubuntu machine, configured pretty much the same way as the main one and I upgraded BTSync to 1.2.91 on it. Here is the output requested

 

1.2.91:

sudo netstat -gn
IPv6/IPv4 Group Memberships
Interface       RefCnt Group
--------------- ------ ---------------------
lo              1      224.0.0.1
eth0            1      224.0.0.251
eth0            1      224.0.0.1
 

Additional info from the same machine:

 

1.2.82:

sudo netstat -npl |grep btsync

sudo netstat -npl |grep btsync
