s3fs: credentials file /etc/passwd-s3fs should not have others permissions

[GoogleCodeExporter]

What steps will reproduce the problem?

When I try and mount the s3fs by doing: /usr/bin/s3fs bucket /mnt/s3/

What is the expected output? What do you see instead?

Instead of a successful mount I receive the following error:

s3fs: credentials file /etc/passwd-s3fs should not have others permissions

What version of the product are you using? On what operating system?

I was using s3fs-1.16 r256 on CentOS 4.4

Please provide any additional information below.

My /etc/passwd-s3fs is using the correct format accessKeyId:secretAccessKey

I decided to use an older version, s3fs-1.10 and everything worked perfectly.

We added a feature which prevents s3fs from running if the permissions file has 
permissions that are too lax. This is for the user's protection -- you wouldn't 
want your AWS credentials to be stolen :) Unfortunately it looks like that 
feature is being overzealous -- we should probably allow 640 for 
/etc/passwd-s3fs, and only 600 for ~/.passwd-s3fs

The solution is just to run:
cp /etc/passwd-s3fs ~/.passwd-s3fs
chmod 600 ~/.passwd-s3fs

Haha well that makes sense. Thanks a lot for the quick response!

Adrian, I think that I got this correct. The error message said "others" 
permission on /etc/passwd-s3fs (not group).  Unfortunately, John didn't give us 
a long listing of /etc/passwd-s3fs to verify this, but I suspect that it had 
others read permission.

Whoops, my bad! So a:

chmod 640 /etc/passwd-s3fs

should do the trick too.

So that confirms what Dan was saying. 640 is okay, 644 is not.
