Hello
I am running Linux 2.6.31 on an iMX25 from Freescale. We have the nbd-server binary (2.9.23 apparently) and we run this command:
/usr/local/bin/nbd-server 9000
/dev/sda1
If an ethernet interface is active in Linux (eth0 or usb0), the nbd-server stays alive and netstat shows the LISTENING status of the 9000 port:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:9000 0.0.0.0:* LISTEN
However, when there is no available interface up in the system (only localhost -loopback), and the nbd-server is started, it won't stay active at all. The netstat -al command does not show the 9000 port as active.
Once an interface is up, the nbd-server actually stays running and listening to the port.
I read the nbd-server manual to see if there were any options to keep the server alive even if no interface is active, but I had no luck.
Do you guys know why this is happening?
Thanks
Regards,
Santiago Villafuerte
