NFSv3

[JOCKYW2001]

Just compiled NFSv3. It's taken from unfs3-0.9.10 and it's the same nfs daemon as our brothers in arms run on the Linksys NSLU2 (aka Allnet6100).

When I run it I get this error:

# ./unfsd
./unfsd: error while loading shared libraries: ./unfsd: symbol xdr_u_long, versi
on GLIBC_2.0 not defined in file libc.so.6 with link time reference
#

I guess I need to build a more up to date 'libc.so'

Any advise on how to build that thingy?

Link statically.

[JOCKYW2001]

Link statically.

Okay, you mean to link statically with the libc.so.6 which sits in /opt/.../mipsel-linux/lib ? By adding a "-lc.so.6" linkparameter?

[Oleg]

Just add this option to link flags

-static

[JOCKYW2001]

Cool Thanks!

Yeah, it looks much better now if I run it I get:
Cannot register service: RPC: Unable to receive; errno = Connection refused
unable to register (NFS3_PROGRAM, NFS_V3, udp).

That's because portmap isn't running which I will now also compile -static

update: Yes!! portmap and unfsd are running

Why are these dynamic link errors at runtime happening? Is the libc.so.6 in the firmware crippled?

[JOCKYW2001]

Okay, I'm almost there, but need some help to mount a NFS share.

My exports is stored on the HDD in /tmp/harddisk/part1/conf/etc and has only one line:
/tmp/harddisk/part1/Movies 192.168.1.91 (rw )

The portmapper and nfs daemon are stored in/tmp/harddisk/part1/conf/bin
I do this to start them:
cd /tmp/harddisk/part1/conf/bin/
./portmap
./unfsd -e /tmp/harddisk/part1/conf/etc/exports

Then on my satbox I try to mount as follows:
/var # mount -t nfs -o soft,udp,rsize=32768,wsize=8192,nolock 192.168.1.220:/tmp/harddisk/part1/Movies /var/movies
mount: 192.168.1.220:/tmp/harddisk/part1/Movies failed, reason given by server: Permission denied
mount: nfsmount failed: Bad file descriptor
mount: Mounting 192.168.1.220:/tmp/harddisk/part1/Movies on /var/movies failed: Invalid argument

Anyone ideas why the WL-HDD refuses this mount?

You mean, that you've launched it with -p switch? There is no portmap, -p just instructs to not use portmap.

Yes, libraries are relinked with only functions needed to minimize it's size.

Yes, tried first -p and it ran. Then I compiled portmap with -static and all is well except for the mount problem (see my prev post)

Where you got portmap?

try (rw,no_root_squash) and check your IP address. Also, you may want try running it in debug mode.

portmap: http://ftp.surfnet.nl/security/tcpwr...rtmap_4.tar.gz
to compile it this helps: http://www.tomsnetworking.com/Sectio...le86-page3.php

YES!!! with no_root_squash I've got a mount.

Oleg, let's drink a wodka together to celebrate!

Ok, the stock one (I just have a thought, that you've found an other one). It's also possible to use it without portmap, but buggy FC2 mount does not allow that now...

[petgun]

hi,
I also like to celebrate :-)...please up your customized firmware somewhere for us..with al little help how to mount ;-)

I can't wait any longer to test it :-)

cu,

YES!!! with no_root_squash I've got a mount.

Check it with MS SFU. It's probably should outperform samba...

[JOCKYW2001]

I'm a very happy camper Works flawless !!!
I can record and playback from my satbox w/o any hickups.
Just tested with Naked Gun 2 1/2

Will do some performance tests with M$ SFU client now

PS: petgun: will contact you tomorrow so that you can dl stuff

Next challenge is to build some automatic start scripts for telnetd, portmap etc.

:-) oh man, you made my day and it's no problem for me to wait until you finnish! Unbelievable, but true..you got your WL-HDD last week and now all my dreams become true :-) I'm sure, the results of your performance tests will motivate many guys here to give NFS a try and I hope your firmware will be upped here in the downloadcenter so everybody can enjoy it.

Thank you very much!
