plutodebug= only logs additionals data. It should not change the behaviour of pluto at all (except I guess some timings due to the additional logging). Are you sure this change is what made it work? ------- Comment From tchicks.com 2008-04-22 19:01 EDT------- Hey Paul - Yes, this must be a timing issue. Turning 'plutodebug="all"' on is definitely the cause. I tried watching /var/log/secure on both machines by doing a 'tail -f /var/log/secure' before I brought up the connection but most of the time it negotiates successfully while tail'ing the log file. Does this somehow speed up the writes while logging??? Also, it doesn't seem to be a problem when using IPv4 addresses. I admit that I'm a little confused on this one. :) This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Any progress on this bug? Setting state to "needinfo." I've been trying to reproduce this bug with openswan-2.6.14-1.el5_2.1 and kernel-2.6.18-92.1.10.el5, but the SA negotiation is always successful when using these updated versions. I'm assuming a fix, possibly inadvertent, has slipped into openswan since the 2.6.11-1 release this bug was originally filed against. Rejecting bug, unreproducible with openswan-2.6.14-1.el5_2.1 and kernel-2.6.18-92.1.10.el5 No known fix was created, but the bug no longer exists. Marking bug as CLOSED Closing bug since testing seems to indicate its fixed. Please reopen if this turns out to wrong. Thanks. |

Removing 'plutodebug="all"' in the ipsec.conf allows for the negotiation to complete successfully. ---Security Component Data--- Userspace tool common name: openswan The userspace tool has the following bit modes: 32 Userspace rpm: openswan-2.6.11-1
