Comment 2 RHEL Program Management 2011-07-06 01:38:48 UTC

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.

Comment 4 RHEL Program Management 2012-05-03 05:41:37 UTC

Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 5 Paul Wouters 2013-02-02 02:48:38 UTC

If this is still the case, please provide some more information, configs, logs etc.

Comment 6 Paul Wouters 2013-04-19 18:07:24 UTC

If this is about the redhat.com vpn, I myself use:

	salifetime=24h
	ikelifetime=24h

Which keeps my connection up for a day.

Comment 7 Paul Wouters 2013-05-17 20:02:30 UTC

I see regular problems too. I think it is related to our end ignoring the IPSEC_LIFETIME received from the cisco, in combination with the Cisco quietly hanging up on us, and not sending us a Delete/Notify.

This happens to my red hat VPN connection too, so I can confirm and test.

We should initiate a rekey based on the receive ipsec lifetime from the cisco (with some margin). Depending on the Cisco requiring new XAUTH credentials, the rekey should either work or fail, but at least we won't have a connection left that silently eats all the packets.

Red Hat Enterprise Linux 6 is in the Production 3 Phase. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available.

The official life cycle policy can be reviewed here:

http://redhat.com/rhel/lifecycle

This issue does not meet the inclusion criteria for the Production 3 Phase and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification. Note that a strong business justification will be required for re-evaluation. Red Hat Customer Support can be contacted via the Red Hat Customer Portal at the following URL:
