get_myaddress error with nfsd

get_myaddress error with nfsd

[Bryan Chua]

I just upgraded my cygwin installation to 1.7.20-1 this morning and my nfsd server no longer starts with this error in /var/log/nfsd.log

get_myaddress: ioctl: Invalid argument

Mountd has the same error but portmap starts fine.

I pulled down the source for nfs-server and only see one ioctl in nfsd.c and one in mountd.c and no references to get_myaddress.

Has anyone else experienced this?  I am not sure where to start looking.

Yesterday I just did a clean installation of Cygwin 1.7.20-1 and I have
experienced exactly the same issue as you - mountd and nfsd don't start
(get_myaddress: ioctl: Invalid argument in logs). Portmap starts fine.

I tried to downgrade sunrpc, but that didn't help.

Ouch.  This is my fault.  When I removed support for OS versions prior
to Windows XP, I accidentally removed support for applications using
ioctl on sockets built under Cygwin versions prior to Cygwin 1.7.

Now, nfs-server has no maintainer and had been built in 2006, so it's
affected by this.

I'm reluctant to revert the old functionality since that re-introduces
code to read network adapter inforation in a way only required up to
Windows XP pre-SP1.

I'm going to think a bit about this problem and try to come up with
another way to support older applications in 1.7.21 again, using only
the current functionality.


Stay tuned,
Corinna

I implemented a solution for this problem which should give sufficent
result to support old applications.  I created a new 32 bit developer
snapshot 2013-06-14 on http://cygwin.com/snapshots/, and I uploaded
a new 64 bit test distro Cygwin release 1.7.21-3, both containing
this patch.

Please give it a try.


Thanks,
Corinna

Re: get_myaddress error with nfsd

Another problem occurred. Both services mountd and nfsd start, but after a
while they stop.

mountd.log says:
Cannot register service: RPC: Timed out
mountd[8860] 06/14/113 21:57 rpcmisc.c 99 : unable to register (mountd, 1,
udp).

And nfsd.log says:
Cannot register service: RPC: Timed out
nfsd[6096] 06/14/113 21:56 rpcmisc.c 99 : unable to register (nfsd, 2, udp).

Windows firewall was temporally disabled when I tested it.

Define "after a while".  I can't reproduce this.  In my case both
services run as long as I don't kill them.

I also had the same issue. I installed the 20130703 snapshot, now everything
works fine - I did not experience any stops "after a while".

Re: get_myaddress error with nfsd

[soccerno16]

I would like to report that this is still an issue with the latest release of
cygwin. (Cgywin1.dll 1.7.25)  I can confirm that the NSFD and MOUNTD
services for the nfs server will die within 10 minutes after starting.  When
i rolled back to Cygwin1.dll 1.7.18 this problem no longer exists.
