kernel+userspace based nfsd running in parallel on linux?

[devzero@web.de]

Hello !

for a special scenario, i´m thinking about running the classic userspace nfsd in parallel with the kernel based.

i think this _could_ be possible by binding the userspace one to the primary interface (eth0, ip 1.2.3.4) and the kernel based one to a virtual interface (eth0:1, ip 1.2.3.5)

i have done similar with other daemons, providing services on the same ports, but on different interfaces - think of apache ip-based virtual hosting which serves www.domaina.com on 1.2.3.4:80 and www.domainb.com on 1.2.3.5:80

since i`m unsure if this would work, can you experts give a comment if this should at least be possible in theory ?

if there isn´t a killer argument against this (does not work by design because...), i would like to try to elaborate to make this work. if this fails because there is no way to specify a dedicated interface to listen on - maybe this could be fixed with some few modifications to the code...

regards
roland
