Testing Scientific Linux


http://www.nux.ro/archive/2011/03/Allow_the_local_user_to_install_and_update_software_without_root_password.html

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.

Then:

Add noncript addon to Firefox and remove Java.

Next, run rpm as intrusion detection system tool as described by Redhat:-
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/4/html/Security_Guide/s2-ids-host-rpm.html

 rpm -Va

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

————————————————————————————————-

example:-

S.5....T c /bin/ps
 
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.
