10.64. indicates Private IP address, and a router being used? so Port
Forwarding in that router should be what you need, but thats a Network

Sorry if this is viewed as spam, but I thought some might be interested.
I actually bought one of these used systems for the family earlier this
year. It looks like brand new, and has been working great (ymmv though).
I figured the price was pretty good considering you get a M$ license.
Shipping from Toronto was free.
To take advantage of this you will need my employee number (020842).
If you'd rather see the site for new equipment, which also has "family and
friends" offers. Let me know.
And …
[View More]no, I don't make any money or get any credit if you avail yourself of
this offer. ;-)

Finally, I have flock locking (oocalc & perl, et al.) working with NFS. I
had to go to NFSv4. NFSv3 appears to not support flock locking even
though the docs make it wound like it will work (but they must be assuming
you're using v4).
NFSv4 is quite the strange beast. You have to make a pseudo-fs and do
wacky server-side binding and non-intuitive client-side mounting.
For anyone who cares, here's the gist of it:
SERVER
/etc/fstab
/data /nfs/data …
[View More]none bind 0 0
/etc/exports
/nfs 192.168.100.1(ro,async,no_subtree_check,no_root_squash,insecure,fsid=0)
/nfs/data 192.168.100.1(rw,async,no_subtree_check,no_root_squash,insecure,nohide)
fsid=0 is critical for the root, and nohide critical for the /data
must run services (on Fedora)
nfs
rpcidmapd
CLIENT
192.168.100.2:/data /data nfs4 rw,bg,hard,intr,nosuid,proto=tcp,timeo=15,retrans=5,rsize=8192,wsize=8192 0 0
note you mount /data not /nfs/data as you would have in v3.
must run services (on Fedora)
rpcbind
rpcidmapd
It looks like you don't need to run nfslock (Fedora) service on either as
it's part of the nfs core now. I'm open to correction on this.
rpcgssd appears to be only required if you want encryption/auth/etc. I
could be wrong on this too.
portmap doesn't seem to be required? Seems to work without it.
I'm still using my custom assigned ports in /etc/sysconfig/nfs and
iptables rules and it seems to work.
I'm still going to use the async option. Most examples show explicit
sync, but in my simple setup I feel the performance gain is worth the risk
as my server is RAID6 with good quality hardware and a beefy UPS. Its
uptime is currently: ;-)
18:22:08 up 445 days, 18 min, 1 user, load average: 0.00, 0.00, 0.00
My next task is to learn more about "crash recovery" for which many pages
say statd is required, but I'm not sure if that's v3 or v4. Sounds useful
but not really critical for my simple setup. I don't care if my locks get
a bit wonky if my server crashes. If anyone has a comment, let me know.

Thanks, I hadn't known about that command. Funny how NFS-relevant
commands and files seem to be everywhere.
The only hints the output gave me was:
1. I'm using v3. Is that ok? Does v3 support locking or are all the net
references talkinga bout v4? I recall I'm using v3 because it has better
recovery characteristics because it's UDP.
…
[View More]2. The v4 sections of nfsstat output show locking parameters, but v3 does
not? Maybe time to try switching up to v4. Doesn't explain why my
loopback tests worked (with locking), when they must have been v3! What
version does everyone else use?
[View Less]
There must be some NFS wizards in the group...
I still can't get NFS locking to work between my 2 linux boxen.
I took the drastic steps of completely disabling my iptables firewalls on
both boxes and setting the policies to ACCEPT. Didn't help.
I also set my NFS server config back to 100% stock (mv /etc/sysconfig/nfs
/tmp/; service nfs restart; service nfslock restart; service rpcidmapd
restart; service portmap restart), remount. Doesn't help.
The test code at the bottom never gets …
[View More]past the flock call. oocalc also
will never get past the splash screen.
I tried exporting and mounting from machine A to machine A (I guess a
loopback-ish mount). For both machine A and B, this works fine. The perl
code runs and oocalc loads up a NFS'd file instantly.
If I mount with nolock in client's fstab, then oocalc starts fine
(probably just ignoring the locks).
I recently upgrade the client box to Fedora 8 (2.6.23). The server is not
easily upgradable and is running 2.6.17. I did a lot of net research and
it seems like NFS flock should work on all kernels after 2.6.12.
I'm stumped! Please help!

I enjoyed Shawn's presentation tonight. For those who would like to try out a
Linux Jails equivalent see http://openvz.org/
Unlike FreeBSD the OpenVZ kernel mods have not made it into the mainstream Linux
kernel. You have to get a kernel from the OpenVZ site.
It is certainly not as easy to configure as Jails but there are templates
available for various Linux distros to make the job easier.
