.nfsxxxx files in homes

[romano r]

Hello,
In several users' homes I found one or more files named eg .nfsFD2F, .nfs7F68, ... inside seems to see something like the .sh_history file.
Has someone an idea about what does generate this files (should be somewhat regardind nfs), but what exactly?

Thank you
Romano

Romano,

Running the strings command against one of them reveals lots of occurences of "AT&T Certificate Services" and "Verisign/RSA Secure Server CA". I'm guessing something from Netscape in secure/encrypted mode. I'm going to try removing them and see what happens.

Romano,

I removed the files and tried accessing a https site. The files did not reappear so I tried accessing a nfs mount point. Still the files did not reappear.

The ones I saw were dated back in 1998. Are yours more recent?

Pete,
yes some user today has generated 2 files, other never.

Romano,

I checked all my other machines (all 11.x) and didn't find any more .nfs* files. I'm wondering if the ones I found were leftovers on my workstation from back when I was running 10.20?

Interestingly enough, a web search on the "Verisign/RSA Secure Server CA" phrase yields lots of results such as this:
http://java.sun.com/products/plugin/1.3/docs/rsa_signing.html
and this:
http://www.verisign.com/support/vendors/issues.html

These all concern signing RSA certificates, though I'm not exactly sure what an RSA certificate is - still working on that one.

Romano,

RSA certificates have to do with SSL connections, probably through your browser. Here's some background (though I'm still looking for something definitive):

We has the same issue some time back. I guess these are nfs lock files created on my NFS servers for the exported filesystems. we resolved it by installing the latest NFS patches for both the client and the server.

Thanks

Sorry to jump in.

At this point, I'd check nfs patching again on both client and server, since the issue is intermittant. Check the patching with swlist against the machine that doesn't have the problem.

Hi Romano,

This document in the itrc knowledge base helps to explain .nfsXXX files.

KBAN00000887

Hope this helps,

Todd

If I really remember this is a bug of the dtfile manager. If you move local files to an nfs mounted dir per drag&drop the file is still local but renamed to .nfsXXXXX.

That is very angry if you move i.e. a 100MB file but you wonder that your filesystem is not decreased about 100MB.

To fix that you must install the latest CDE/NFS Cumulative Patches
