"spontaneous" permissions changes
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi all, I have a strange situation I wish someone could help me with. This is the setup: - Virtual machine running the latest VM under ESXi - VM has one processor, 2 GB RAM, 1 GB swap - Ubuntu 8.04 LTS - The virtual host runs only this VM - Virtual host connects to a Lefthand Networks (now HP) SAN through 1 GB copper ethernet and iSCSI - VM has a 1 TB volume from the SAN that looks like a SCSI drive to Linux (/dev/sdc) - sdc is formatted as one big ext3 partition (sdc1) - sdc1 is exported both as an NFS resource and a SMB share (via Samba) - Authentication is Kerberos and authorization is local, if that mattersThe permissions on that partition's mount point, usually 755, changed suddenly to 400. I have looked at sudo logs, root's and all admins' history files and I can find no evidence of someone changing those permissions or of tampering with the logs.
Physical access to the box requires the right keycard; logon (ssh) access to the box is restricted to sysadmins and support personel only; the root password is a 32 char long random string that lives in an encrypted repository on my iPod Touch. There are only 2 people, myself included, with full sudo rights; there are another 5 people with sudo rights to a number of administration things including chmod.
This is a state university and it happened on the first day of classes. My questions: - Did I look everywhere I should be looking to find evidence of foul play?- Does anyone know of anything in this setup that could trigger a seemingly spontaneous permissions change like that?
