ok.. i stopped the firewall .. double and even tripple checked that the service is running correctly on the server .. i tried with another PC linux ..

from the other pc i typed :

showmount -e <myIP>

the shared folder appeared after a while .. (about 5 seconds at first..faster next)

but when i tried to mount .. it said" RPC timeout" after a loong while ..

i tried to mount from the uCinux .. it said the following:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

/> mount 192.168.0.122:/home/tarek/Desktop /mnt

mount: RPC: Timed out

mount: nfsmount failed: Bad file descriptor

mount: Mounting blaBla on Blabla failed: Invalid Argument[/b]

--- Quote End ---

Did you see such thing before..? .. sorry ..i am still a starter ..

I had spent about 4 hours till now just trying .. no results.. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

thanks for helping .. and waiting for the next clue from you .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

Bye

i also tried the following ..

/> mount -t nfs 192.168.0.122:/home/tarek/Desktop /mnt
portmap: server localhost not responding, timed out
RPC: failed to contact portmap (errno -5).
portmap: server localhost not responding, timed out
RPC: failed to contact portmap (errno -5).
lockd_up: makesock failed, error=-5
portmap: server localhost not responding, timed out
RPC: failed to contact portmap (errno -5).

You need the -o nolock in mount flags.

mount -t nfs -n -o nolock,rsize=1024,wsize=1024 192.168.1.2:/home/nios2 /mnt/nfs

( eg, server ip 192.168.1.2)

Look in the wiki carefully.

But why you failed to mount nfs from another linux pc?

i did ... the same error

i began thinking that the server itself has a problem .. i have fedora core5 .. so i tried the server on a different pc .. having fedora core 4 .. the same results :S

when i type " rpcinfo -p " ..

i can see many prgz.. portmapper,status,nfs,nlockmgrrquotad,mountd ..

all of them have both TCP and UDP versions .. with more than one version..

i am very confused http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

thanks for your reply..

and still waiting ... for the next clue . http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

sorry .. for continuous replies..

i tried this

mount -t nfs -o nolock 192.168.0.122:/home/tarek/Desktop /mnt/test

i did not set the rsize or the wsize.. it did NOT give an error ..

but when i tried to " cd /mnt/test " it gave a " permission denied " http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

Darkness inside confusion ,, this is how i feel now http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/laugh.gif

what is your /etc/exports file ?

/home/nios2 192.168.1.0/255.255.255.0(rw,no_root_squash,sync)

you need the no_root_squas flags,

And try disable selinux in FC4/FC5 with "securify level" config.

Cheer up. you are not alone.

HIPPO ... thanks a LOOOT http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

it appeared to be permission issue ..

i changed the permission of " /home" and "/home/tarek" and "/home/tarek/Desktop" so that everybody can change the files.. it worked ..

about your question: yes i use the flag:

/home/tarek/Desktop 192.168.0.0/255.255.255.0(rw,no_root_squash,sync)[/b]

but .. a last question please .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

the mount works as read-only.. i need write access to save my outputs on my PC .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif

Anyway .. THANKS A LOT .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

you are very close now.

you&#39;d better not use the Desktop dir, it is used by desktop manager.

try

mkdir /home/nios2

chmod -R a+rw /home/nios2

and export /home/nios2,

i tried it .. i gave the same result !!

i tried making and mounting /uc (i thought the permission of /home had problems)

this also gave the same results http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

Hippo .. thanks for your patience ..

could this be a client problem ?
