[Samba] Should there be a process listening on port 135?

[John McLean]

I'm running samba 4.1.2 on Linux Mint 15. Getting the following:
 
./samba-tool drs kcc samba-realm
Failed to connect host 192.168.231.132 on port 135 - NT_STATUS_CONNECTION_REFUSED
Failed to connect host 192.168.231.132 (samba-realm) on port 135 - NT_STATUS_CONNECTION_REFUSED.

I don't see samba or smbd listening on port 135. 53 and 137 are. e.g.:
 
netstat -anp | grep samba | grep ":53"
tcp        0      0 0.0.0.0:53              0.0.0.0:*               LISTEN      2694/samba

netstat -anp | grep samba | grep ":137"
udp        0      0 127.0.0.1:137           0.0.0.0:*                           2694/samba

udp        0      0 192.168.231.255:137     0.0.0.0:*                           2694/samba      
udp        0      0 0.0.0.0:137             0.0.0.0:*                           2694/samba
 
But not 135. Other things, like samba_dnsupdate and smbclient appears to give expected output, so some things seem to be configured okay.
 
Thx. J.
