I have 2 OpenBSD machines providing a bridge between 2 physical locations for a specific subnet. Last night, I got the following error messages on them:
Oct 28 07:23:13 pb48 isakmpd[11605]: message_recv: invalid cookie(s) +0e113721bf798717 6b4e0004066c308e Oct 28 07:23:13 pb48 isakmpd[11605]: dropped message from 10.209.120.15 port 500 +due to notification type INVALID_COOKIE and on the other: Oct 28 07:23:13 pblab isakmpd[2851]: message_recv: invalid cookie(s) +0e113721bf798717 6b4e0004066c308e Oct 28 07:23:13 pblab isakmpd[2851]: dropped message from 10.209.142.156 port +500 due to notification type INVALID_COOKIE Would I be correct in assuming thta these indicate packet coruption on the network connecting these 2 machines? BTW, we have been having a lot of trouble with UDP based protocols here, I have even switched NFS over to TCP to try to work around this. Is this error UDP? Or TCP? -- One of the main causes of the fall of the roman empire was that, lacking zero, they had no way to indicate successful termination of their C programs.
