Greetings;
I have a weird problem in that I seem to be able to access the remote
machine, except for the most important directory on it, /home. An
ls /net/machine/home
ls: cannot access /net/shop/home: Stale NFS file handle
Expected this
sudo ls /net/shop/root
permission denied
But every other actually exists on the drive directory is ls'able.
I've restarted all the nfs related stuff, everything but rebooted
this machine.
Subject says it all. I need to find the experts.
Cheers, Gene Heskett

Aside from the usual cricket havens (kernel mailing lists, where no one
seems able to answer your questions ;-)) you might try the Arch Linux
boards of all places. There are a lot of knowledgeable people there, and
if you can distill the issue down enough you might get by even though you
are using a different distro. :-)
That said, stale handle normally means the client has been disconnected
from the server without knowing why; since you can access other
directories on that server I'd be looking at:
1.) permissions on the server side
2.) Stale / broken portmapper / RPC services
3.) Any firewalls between the two boxes, possibly blocking only certain ports
If it isn't any of the easy things like that you're going to have to use
Wireshark and get packet traces.

Twasn't installed, is now, gave me hell for running it as root (sudo) but won't
trace eth0, no perms, if I don't. I let it capture about 500 packets including a
couple directory listings on "shop", but even though I expanded every
interchange between here and shop, that isn't a thing there to identify that fact that
I am trying to do, or just did, a directory listing. So I can't connect what I'm
seeing in the capture compared to what I typed and received a response to in a different
workspace/terminal.
IOW, I am lost. BTDT, several times now. ;-)
I have to assume the man page will tell me what to do, so I'll see if I can suss it
out.
A query on the debian list made last night has so far been ignored. And I am not subbed
to the arch list, but it sounds like I should be.
Thank you Timothy.

Hi Gene!
I dropped NFS on linux ages ago, due to simillar issues as you
describe. Now I use SSHFS and haven't had any issues since then. So,
what about using SSHFS instead of NFS?
Nik
Never heard of it till now. So I installed it, along with sshmenu which
pulled in a dozen other rubyish packages.
Silly Q though, does mc understand sshfs? Or do I need to find a new 2
pane file manager that does understand it?
One thing's for sure, NFS, even V4 is old enough to have bit rot.
Thanks Nik. Off to read some man pages.

Hi Gene!
SSHFS is just like any other filesystem, so mc has no problems with that. But may I ask,
what you do with sshmenu? Usally I just mount remote directories like that:
sshfs nik@somehost:/just/the/path /where/i/want/it
and unmount:
fusermount -u /where/i/want/it

On the MC command line, do cd fish://user_name@machine_name
This makes one of your panels a virtual file system on the other machine.
There is also a fish kpart that you can use from konqueror in file browser

You have to have an SSH server daemon running on the remote machine, of
course. Also, the transfer rates will be slower than NFS, if that matters.

Well, as a sample fstab entry, I have gotten as far as its asking for a
root password, something that does not exist on any of my debian
installs. and of course my pw, used with sudo, is no good.
How do I go about telling it I am the user doing the mounting and if
needed, the unmounting? "defaults,idmap=user" in the fstab apparently
does nothing. As a test, miss-spelling user does get bounced.

But a "cd /sshnet/shop", after using Niks's example sshfs command, a
mount point I created, then chown'd to me, works just fine. Since I
also have an ssh -Y session into each of those machines, if I need to
muck around out of my home dir, sudo is always available.
To summerize, I added these lines to /etc/fstab:
shop.coyote.den:/ /sshnet/shop fuse.sshfs defaults,idmap=user 0 0
lathe.coyote.den:/ /sshnet/lathe fuse.sshfs defaults,idmap=user 0 0
GO704.coyote.den:/ /sshnet/GO704 fuse.sshfs defaults,idmap=user 0 0
Which I suspect can be nuked. but there it is. The mount points were
created and chown'd to me.
Now I will see if the fstab entries are surplus by doing the same thing
to each of the other 3 machines currently alive on this local network.
Then I can hopefully reach across the net from any machine to any
machine, which was my target in the first place.
According to my results of doing the mkdir yadda, followed by the sshfs
login, it works just fine on GO704. I can look at /home/gene on this
machine from the ssh -Y session into that machine. Two more machines
to go... But first, clean up the mess in my fstab.
Oh, and sshmenu is broken, needs a ruby dependency the deb didn't list. I
don't have a heck of a lot of ruby stuffs in use here. I'll nuke it.
Nik's example sshfs command line was then executed once for each of the
mount points.
Humm, on GO704 it all works, and here it all works BUT the sshfs session
converts the individual subdir used from gene:gene to root:root.
If thats permanent it will be a problem.
So I go over to the ssh -Y session into the lathe and do the mkdir
tapdance again. But while it will connect to both this machine and
GO704, it will not connect to "shop", "connection reset by peer", so
once again that shop machine is being a spoiled brat.
Doing that same tapdance on machine "shop" works as expected.
Now why can't lathe access shop?
gene@lathe:~$ sshfs gene@shop:/ /sshnet/shop
read: Connection reset by peer
However, gcode written for the lathe (only a 2 axis machine) is not
usable on shop or GO704 which are 4 axis milling machines, so that is
not a showstopper loss. Besides, I can go to the other machine and do
the file copies if I need it bad enough.
What does bother me though is that if the ownership
of /sshnet/machinename being changed to root is permanent, that will
mean I have to do the "sudo chown -R /sshnet" dance on 4 machines when
they have been rebooted. That is the only way I know to get around the
target machines asking me for a non-existent root pw.

My local linux user group. Chuckle. I am 1 of a group of 3. Not
too many linux users in these here parts. I am quite likely 100
miles from the nearest "user group" that numbers 10 or more.

Hi Gene!
I dropped NFS on linux ages ago, due to simillar issues as you
describe. Now I use SSHFS and haven't had any issues since then.
So, what about using SSHFS instead of NFS?
Nik NFS these days is a hairball of epic proportions. Try
getting the NFS
daemons to bind to a specific address per the man pages...
And has been so for at least 5 years, the level of neglect seems rampant.
The manpages haven't been touched in 9 years.
But till now I have used it if I could because there wasn't a usable
alternative. I long ago got tired of the constant perms fixing that CIFS
needs, too many roots in the M$ world.

Many many thanks to both Nik and Richard for supplying the clues and
examples that made it work . And to Timothy for pointing out that it
might be a problem with rpcbind. But yesterdays huge update included
rpcbind, which all machines have now been updated, and that did not fix
nfs.

This makes one of your panels a virtual file system on the other
machine. There is also a fish kpart that you can use from konqueror
in file mode.

Ok, this is the workflow you need to go through for each maschine - all steps, including

Plese make sure, that you do not use any passphrase, or you'll need to enter it each

# walk-the-shop, round 1: recreate SSH-keys for all maschines
rm ~/.ssh
ssh-keygen
# round 2: distribute ssh public keys, you'll need this for all 3 maschines, not just
the other 2:
ssh-copy-id -i ~/.ssh/*.pub gene@this_one
ssh-copy-id -i ~/.ssh/*.pub gene@the_other
ssh-copy-id -i ~/.ssh/*.pub gene@the_next_one
# round 3: check, if you can log into any of these maschines without password:
ssh gene@this_one
ssh gene@the_other
ssh gene@the_next_one
# round 4: reboot, try round 3 again for all maschines.
# round 5: try mounting sshfs for all 3 maschines:
sudo bash
su - gene -c "sshfs gene@shop:/ /sshnet/shop"
su - gene -c "sshfs gene@shop:/ /sshnet/coyote"
su - gene -c "sshfs gene@shop:/ /sshnet/lath"
# round 6: add the lines above to /etc/rc.local, reboot and check if it worked
Now, does this procedure fail anywhere?
If yes, what linux versions are running where?

But a "cd /sshnet/shop", after using Niks's example sshfs command, a
mount point I created, then chown'd to me, works just fine. Since I
also have an ssh -Y session into each of those machines, if I need
to muck around out of my home dir, sudo is always available.
To summerize, I added these lines to /etc/fstab:

defaults,idmap=user 0 0 GO704.coyote.den:/ /sshnet/GO704
fuse.sshfs defaults,idmap=user 0 0
Which I suspect can be nuked. but there it is. The mount points
were created and chown'd to me.
Now I will see if the fstab entries are surplus by doing the same
thing to each of the other 3 machines currently alive on this local
network. Then I can hopefully reach across the net from any machine
to any machine, which was my target in the first place.
According to my results of doing the mkdir yadda, followed by the
sshfs login, it works just fine on GO704. I can look at /home/gene
on this machine from the ssh -Y session into that machine. Two more
machines to go... But first, clean up the mess in my fstab.
Oh, and sshmenu is broken, needs a ruby dependency the deb didn't

Nik's example sshfs command line was then executed once for each of
the mount points.
Humm, on GO704 it all works, and here it all works BUT the sshfs
session converts the individual subdir used from gene:gene to
root:root. If thats permanent it will be a problem.
So I go over to the ssh -Y session into the lathe and do the mkdir
tapdance again. But while it will connect to both this machine and
GO704, it will not connect to "shop", "connection reset by peer", so
once again that shop machine is being a spoiled brat.
Doing that same tapdance on machine "shop" works as expected.
Now why can't lathe access shop?
gene@lathe:~$ sshfs gene@shop:/ /sshnet/shop

However, gcode written for the lathe (only a 2 axis machine) is not
usable on shop or GO704 which are 4 axis milling machines, so that
is not a showstopper loss. Besides, I can go to the other machine
and do the file copies if I need it bad enough.
What does bother me though is that if the ownership
of /sshnet/machinename being changed to root is permanent, that will
mean I have to do the "sudo chown -R /sshnet" dance on 4 machines

Hi Gene!
Ok, this is the workflow you need to go through for each maschine -
all steps, including new key generation etc. Plese make sure, that you
do not use any passphrase, or you'll need to enter it each time you
use sshfs:
# walk-the-shop, round 1: recreate SSH-keys for all maschines
rm ~/.ssh
It won't let me, complains its a directory, which it is, and contains
known_hosts and known_hosts.old

Resource temporarily unavailable, fish might not be installed?
But a "cd /sshnet/shop", after using Niks's example sshfs
command, a mount point I created, then chown'd to me, works just
fine. Since I also have an ssh -Y session into each of those
machines, if I need to muck around out of my home dir, sudo is
always available.
To summerize, I added these lines to /etc/fstab:
shop.coyote.den:/ /sshnet/shop fuse.sshfs
defaults,idmap=user 0 0 lathe.coyote.den:/ /sshnet/lathe
fuse.sshfs
defaults,idmap=user 0 0 GO704.coyote.den:/ /sshnet/GO704
fuse.sshfs defaults,idmap=user 0 0
Which I suspect can be nuked. but there it is. The mount points
were created and chown'd to me.
Now I will see if the fstab entries are surplus by doing the
same thing to each of the other 3 machines currently alive on
this local network. Then I can hopefully reach across the net
from any machine to any machine, which was my target in the
first place.
According to my results of doing the mkdir yadda, followed by
the sshfs login, it works just fine on GO704. I can look at
/home/gene on this machine from the ssh -Y session into that
machine. Two more machines to go... But first, clean up the
mess in my fstab.
Oh, and sshmenu is broken, needs a ruby dependency the deb
didn't list. I don't have a heck of a lot of ruby stuffs in use
here. I'll nuke it.
Nik's example sshfs command line was then executed once for each
of the mount points.
Humm, on GO704 it all works, and here it all works BUT the sshfs
session converts the individual subdir used from gene:gene to
root:root. If thats permanent it will be a problem.
So I go over to the ssh -Y session into the lathe and do the
mkdir tapdance again. But while it will connect to both this
machine and GO704, it will not connect to "shop", "connection
reset by peer", so once again that shop machine is being a
spoiled brat.
Doing that same tapdance on machine "shop" works as expected.
Now why can't lathe access shop?
gene@lathe:~$ sshfs gene@shop:/ /sshnet/shop
read: Connection reset by peer
However, gcode written for the lathe (only a 2 axis machine) is
not usable on shop or GO704 which are 4 axis milling machines,
so that is not a showstopper loss. Besides, I can go to the
other machine and do the file copies if I need it bad enough.
What does bother me though is that if the ownership
of /sshnet/machinename being changed to root is permanent, that
will mean I have to do the "sudo chown -R /sshnet" dance on 4
machines when they have been rebooted. That is the only way I
know to get around the target machines asking me for a
non-existent root pw.

And has been so for at least 5 years, the level of neglect seems
rampant. The manpages haven't been touched in 9 years.
But till now I have used it if I could because there wasn't a
usable alternative. I long ago got tired of the constant perms
fixing that CIFS needs, too many roots in the M$ world.

Many many thanks to both Nik and Richard for supplying the clues
and examples that made it work . And to Timothy for pointing
out that it might be a problem with rpcbind. But yesterdays
huge update included rpcbind, which all machines have now been
updated, and that did not fix nfs.

Hi Gene!
Plese check that the file /etc/ssh/sshd_config is identical for
all 3 maschines. On rebooting: you could add the "sshfs
..." lines to
/etc/rc.local:
su - gene -c "sshfs gene@shop:/ /sshnet/shop"
And this bypasses the pw request for my pw from each machine as its
called to duty?
.. then you sould have the user of the remote
files set to "gene".
Also check that the subfolders of /sshnet/* are owned by "gene"
when no filesystem is mounted there.
Nik
Thank you Nik.
Cheers, Gene Heskett ssh-keygen
# round 2: distribute ssh public keys, you'll need this for all 3
maschines, not just the other 2: ssh-copy-id -i ~/.ssh/*.pub
gene@this_one
ssh-copy-id -i ~/.ssh/*.pub gene@the_other
ssh-copy-id -i ~/.ssh/*.pub gene@the_next_one
Done, had to use my login pw for this.
# round 3: check, if you can log into any of these
maschines without
password: ssh gene@this_one
ssh gene@the_other
ssh gene@the_next_one
Works!
# round 4: reboot, try round 3 again for all maschines.
# round 5: try mounting sshfs for all 3 maschines:
sudo bash
su - gene -c "sshfs gene@shop:/ /sshnet/shop"
su - gene -c "sshfs gene@shop:/ /sshnet/coyote"
su - gene -c "sshfs gene@shop:/ /sshnet/lathe"
# round 6: add the lines above to /etc/rc.local, reboot and check if
it worked
It should, I already added that stuff in my rc.local.
Now, does this procedure fail anywhere?
No. :)
If yes, what linux versions are running where?
Nik
Thank you very much Nik.
Cheers, Gene Heskett
