NFS issue

[Mike_449]

Hello to all

Somebody can give me,

What does "-anon=65534" & "-async" signify in the /etc/exports file?

Thanks a lot

Hi Mike,

It means that:

1) Any anonymous NFS connection is assigend the UID of 65534 and thusly it's permissions.

2) All writes will be signified as "complete" even though they may still be in the buffer. This "speeds up" an application that waits for the "physical" write. But that comes at a data security risk....No such thing as a free lunch.......

HTH,
Jeff

-anon=65534 means any nfs requests coming will be assigned uid=65534, but surprisingly i have never seen this setup its mostly assigned to -1 or -2

-async means the nfs writes will be asyncronous, which gives a better nfs performance.

hi,

65534 means the uid of anonymous user so it maens any anonymous user can acces this exported filesystem .

-async means the data will not be write to physical disk on the same time.
