Re: [Nbd] [RFC]nbd-client connect error
Hi Harry,
I've removed a few lists that this has little relevance to. In the
future, please direct your nbd-related questions to the nbd-general
list.

Which version of the server is this?
If it is 2.9.17 or later, you will need an additional option
"oldstyle=true" in the generic section.

So, I've set up a VM running CentOS5, and have installed nbd there:
[wouter@...920... nbd-2.9.23]$ sudo ./nbd-client debsrv 1234 /dev/nbd0
Negotation: ..size = 2048MB
bs=1024, sz=2147483648 bytes
[wouter@...920... nbd-2.9.23]$ uname -r
2.6.18-238.12.1.el5
in other words, I can't reproduce this.
Is it possible that your /root/1.c file is 0 bytes large? If so, please
make a larger file first (e.g., by using 'dd if=/dev/zero of=/root/foo
bs=1k skip=1M count=0') and export that one.
