[Samba] CTDB Error / tcp port 445 not repsonding

[Vogel, Sven]

Hi Gaiseric,

yes i have these setting. Testparm -v

smb ports = 445 139

i mean with ad (active directory). I know that ctdb not uses 445 but ctdb starts samba and wait for startup from samba. Maybe ctdb check some responses from samba and wait for startup from samba. If there is not correct response it send these error message.

I think ctdb is correct configured. is there any way to debug the samba connection problem? I can set the debug level ... 

Thanks

Sven

You stated "ctdb cluster uses winbind for connection to the ad."   When 
you say "ad" do you mean active directory or something else?     I don't 
use CTDB so I was trying to figure out if you had some network issue that was not specifically related to CTDB.


On my samba servers

#testparm -v

         smb ports = 445 139


This is the default.   I had tried setting "smb ports" to only use 139 
-  since supposedly  clients in a Samba 3.x domain don't use it.     
Port 139 is for CIFS (windows file services) over Nettbios-over-tcp.   
Port 445 is for CIFS-over-IP.           It turns out displaying 445 
actually caused problems.       Windows 7 machines can use 445 for file 
access (not for authentication though)   so disabling 445 caused 
problems if a router was involved.


It doesn't look like CTDB uses 445-   which is why I think there may be 
some other issue.

Are you using a VPN tunnel between sites?
