I am trying to get a small office network to share data between two linux machines:

Topography
\/<-Computer1 w/ Static Public IP
|
DSL =>ROUTER(using nat)
|
/\<-Computer 2 using NAT'd internal DHCP

The /etc/exports file is good on Computer1 with the public IP

The /etc/hosts is set up properly on Computer 2 as is the HOSTNAME in /etc/sysconfig/network.

I can ping Computer 1 using computer 2 but when I try to mount the nfs partition I get an error message saying that the "Permission Denied" by the server?

Ultimately I would like to have my computers set up in the following topography...but need to sort out the NFS problems.

\/<-Computer1 w/ Static Public IP (RH9.0)
|
DSL =>ROUTER(using nat) \
|
/\<-VoIP MTU (digital phone w/ static public IP)
|
/\Computer 2 using NAT'd internal DHCP of MTU
(Mandrake 9.1)

This configuration has two internal networks and the public network. Still, I can ping Computer 2, I can ssh, sftp, etc. to Computer1....I just can't get an NFS connection.

I am curious to know if Samba may be the best alternative in this scenario. I realize that it is geared towards sharing with Windows clients, but it doesn't base permissions soley on hostname and/or address and allows access via an individual ACL.

Seen a couple of posts similar to this..but no anwers.

Any help/feedback would be greatly appreciated.

have you added a portmap section to hosts.allow on you server.

for example portmap: 10.0.1.97
where 10.0.1.97 is replaced with your dsl routers public ip.

Another approach since you have 2 offices is to setup a vpn between them, routers these days even have this functionality. then all you office computers can see each other as if they were all on the same network.

just on the voip thing, digital phones like about 128kbit bi-directional transfer. so if both offices have a 1.5m/256kbit link you will only be able to hold 2 GOOD quality phone calls. so you should also look into getting something like a synchronous 512/512 link. And the vpn is the best solution as it will solve the ip phone thing at the same time.

Hey!
Even I am getting the same error "Permission denied"
Did u get a solution to your problem#1
Kindly share it with me

No luck, I've just made up a shaky temp solution by settting my server name into the hosts file and simply sftp'ing the other server to get files. Not fast and not practical for a permanent solution...but it lets me work for the time being.

I guess one could do it via Samba, but the system overhead is pretty high to use it as a final solution.

Like you, would be grateful to find how to make it work. Maybe the new kernels will allow for something like this.??
