[Samba] Shutdown of nmbd process in SAMBA 2.2.3a
Hi, I am running SAMBA 2.2.3a on HP-UX 11.00. Last night the network switch that my SAMBA servers is on was rebooted. At this same time the nmbd process on all my servers shutdown down. In the /usr/local/samba/var/nmbd.log file on all my servers I found this message : [2002/04/03 20:39:28, 0] nmbd/nmbd.c:(259) reload_interfaces: No subnets to listen to. Shutting down... Anyone have any ideas why the nmbd would shutdown when the network connection was lost? Is there a parameter that I can change for this?

[Samba] Shutdown of nmbd process in SAMBA 2.2.3a
Hi Drew, No, there is no parameter you can change for this. nmbd is CODED to shut down if there are no interfaces to listen on - it discovers this in a routine called "reload_interfaces(t)" which is called (along with other things) after a sighup has been received, OR every 120 seconds (as defined by include/local.h:#define NMBD_INTERFACES_RELOAD (120)). So, bottom line, if this code happens to execute during your switch reboot, causing nmbd to NOT find any interfaces, this behavior is expected. You COULD minimize the window for this to happen by changing the code to make the NMBD_INTERFACES_RELOAD happen less frequently, but you could still hit it, of course. I would hope that this switch reboot should be an infrequent thing, though, and probably not worth this type of coding effort.

[Samba] Shutdown of nmbd process in SAMBA 2.2.3a
Don, Thanks for letting me know, I was not aware of the nmbd doing that check (although it does make sense). The reboot of our switches should be infrequent, unfortunately, sometimes these things are not scheduled due to problems with the switches. (for example last night). I do agree though that it may not be a frequent enough event to justify the large effort of coding (I have been with SAMBA here for about 4 years and this is the first time I have ever hit this), although it maybe something to consider adding to the wish list for future versions if/when there is time.
