Testing Scientific Linux

After installing SL6, I tried to run the software update tool, but policykit gave a warning about software from untrusted source. I googled for the error and came up with the above link that allowed the updates to run.


Add noncript addon to Firefox and remove Java.

Next, run rpm as intrusion detection system tool as described by Redhat:-

 rpm -Va

This is the output, and description of what it all means is underneath.

the file has been modified in some way and you must assess whether to keep the file (such as with modified configuration files in the /etc/ directory) or delete the file and reinstall the package that contains it. The following list defines the elements of the 8-character string (S.5....T in the above example) that notifies of a verification failure.

  • . — The test has passed this phase of verification
  • ? — The test has found a file that could not be read, which is most likely a file permission issue
  • S — The test has encountered a file that that is smaller or larger than it was when originally installed on the system
  • 5 — The test has found a file whose md5 checksum does not match the original checksum of the file when first installed
  • M — The test has detected a file permission or file type error on the file
  • D — The test has encountered a device file mismatch in major/minor number
  • L — The test has found a symbolic link that has been changed to another file path
  • U — The test has found a file that had its user ownership changed
  • G — The test has found a file that had its group ownership changed
  • T — The test has encountered mtime verification errors on the file

    Next: I have one MS app that I need, so install Virtual XP in KVM.

    By default, libvirt stores images in the /var/lib/libvirt/images directory. The root user owns the /var/lib/libvirt/images directory. Therefore, only the root user can create files, delete files, and view a listing of the files in the /var/lib/libvirt/images directory.This is where the clone ended up after I made it.
