[SOLVED]Init using port 445? Can't start samba, Address already in use

denn1s · 2014-05-25 23:51:05

Samba is disabled in my system at startup.

# systemctl status smbd    
* smbd.service - Samba SMB/CIFS server
   Loaded: loaded (/usr/lib/systemd/system/smbd.service; disabled)
   Active: inactive (dead)
#

When I try to start samba, I get an error message on the log that says that samba can start because port 445 is in use. If I change samba's configuration to use another port it starts fine.
However I would like to know why I can't use port 445. Running netstat after a fresh boot shows this:

#  netstat -tulpn
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp6       0      0 :::445                  :::*                    LISTEN      1/init           
#

Why does it say that init is listening on port 445? Do you think it's related to some misconfiguration with samba or an issue with systemd? I can confirm that smbd is not running via ps ax.
I use samba to connect from a mac laptop and even if I change the default port the connection fails. I have tried nfs as an alternative but didn't really like the fact it uses no password.

This is samba's message log:

My system is up to date and my samba version is Version 4.1.7. Thanks in advance to everyone that took the time to read my question.

Have you enabled smbd.socket?

Thank you. I hadn't tried enabling smdb.socket but it seems samba still can't start

On a side note, nmbd runs fine with no issues.

You misunderstood what I meant; if smbd.socket is enabled, that would explain why port 445 is in use -- systemd is listening on the port so that it can start up smbd when it is called for. This is what a .socket unit does.

denn1s · 2014-05-26 01:07:21

I see, that was precisely the problem, thank you. I must have enabled the socket without realizing it at some point, disabling smbd.socket solves the issue. I still can't connect from my laptop but it's surely a different issue, marking the thread as solved.
