It communicates via standard input (just like inetd). Obviously newer versions do not need this anymore, and smbd will detect in which mode it is supposed to run.
That switch was once introduce in 157777ef3e to add "Samba 3 support". Maybe you can check with the samba guys if that switch was actually ever required or since when it became redundant. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/988128 Title: smbd crashes when called with "smb ports = 0" Status in QEMU: New Bug description: The smb.conf generated by qemu-kvm contains a "smb ports = 0" directive. This causes at least version 3.6.4 of Samba to crash with [0] vostro:/tmp/qemu-smb.6836-0# smbd -i -s smb.conf Unable to setup corepath for smbd: Operation not permitted smbd version 3.6.4 started.

I'd like to help fix this, but I am not sure what qemu-kvm's intention is here. Zero is not a valid port, and the smb.conf manpage does not describe any special meaning of zero here. I found that previous versions of samba apparently did not bind to any port if zero was specified - but in that case, how is qemu communicating with samba?
