Hi Scott ,

I added mtab and fstab to /etc of the Cyclone uClinux filesystem (I added fstab since if I I had added mtab ONLY , uClinux would have asked me for fstab)

Here are the contents of both mtab and fstab :

portmap:192.168.1.19

lockd:192.168.1.19

rquotad:192.168.1.19

mountd:192.168.1.19

statd:192.168.1.19

where 192.168.1.19 is the IP of Linux PC

I think these files set the connection TO the Linux PC we want to mount. (?????)

Also , I have added a step :

4a) In Linux PC , open /etc/hosts.allow as ROOT and add the following to the file :

portmap:192.168.1.20

lockd:192.168.1.20

mountd:192.168.1.20

statd:192.168.1.20

where 192.168.1.20 is the Cyclone IP

(the content of hosts.allow accepts the connection from the machines in the list)

At step 6), run the command :

mount 192.168.1.19:/home/mymnt /var

The following error occurred :

mount: rpc: port mapper failure - rpc: unable to receive

About this error , I thaught that I "opened" connection between Linux PC (/etc/hosts.allow) and Cyclone (fstab , mtab). Do I have a lack of some step ?

What do you think ?
