FIPS breaks SSH and telnet access to/from RHEL6.5-Beta system
Last modified: 2013-10-16 10:26:12 EDT
Description of problem:
Both telnet and SSH access to/from a newly-IPLed RHEL6.5-beta system work initially, but stop working at some point, generating FIPS errors. Not seen in RHEL6.5-Alpha. The following procedure fixes the issue, at least temporarily:
Version-Release number of selected component (if applicable):
Unsure how to reproduce it on demand, but it has appeared several times in our testing of RHEL6.5-Beta. Every system under test has experienced this.
Steps to Reproduce:
Unknown. IPL the system and use it for a while, and it will happen.
SSH and telnet will start generating FIPS errors to the outside and access inbound will become blocked.
SSH and telnet shoudl continue to work normally.
This should be fixed in the latest openssl and openssh packages.
Can you update them and retest?
Also do you have dracut-fips package installed? You should not unless you want to run the system in the FIPS mode.
This appears to only happen in RHEL6.5-Beta. We have not seen it in RHEL6.5-Snap1 or RHEL6.5-Snap2, and it did not happen under 6.5-Alpha.
(The dracut-fips package is being installed, though we probably do not actually need for it to be. That doesn't seem to be causing problems when running 6.5-Snap1 or 6.5-Snap2.)
I think you can close this bug since it seems to be fixed now, or maybe mark it as a duplicate of 1010945 if you think it is the same thing. We will reopen it if it comes back.
