NFS Insecure Access to Secure Export

Description

User tries to access a secure export from an insecure port.

Cause

Secure export requirement means that the accessing clients must

 

use a well-known port (below 1024), which usually means that they

 

must be root (uid=0) on the client.

Workaround

• Identify the relevant export and verify that it is set as secure

 

(requires secure client port).

If the export must remain secure, see the NFS client documentation in order to issue the mount request from a well-known port (below 1024).

If a secure export is not required (e.g., the network is not public), ensure that the export is insecure and retry accessing it.

NFS Mount Fails Due to Export Options

Description

This event is issued when NFS mount fails due to export options.

Cause

The export list filters client access by IP, network or netgroup, and

 

screens the accessing client.

Workaround

1

Verify the relevant export details. Write down all existing options

 

 

so that you are able to revert to them.

 

2

Remove IP/client restrictions on the export and retry the mount.

 

3

If the mount succeeds, verify that the IP or domain is explicitly

 

 

specified, or that it is part of the defined network or netgroups.

 

 

Pay attention to pitfall scenarios, where the network netmask is

 

 

not intuitive, for example, 192.175.255.254 is part of

 

 

192.168.0.0/12 but not of 192.168.0.0/16.

 

4

Once the mount succeeds, adjust the original options accordingly.
