Brian .... I had this issue this weekend in 8.6. My original issue was the "no home uds cluster" but I had issues with the proxy protocol violation.
Tac's response was go to 8.6.1 (released 9/11/15 ... yikes) or roll back to 8.5 Thanks, Ryan -------- Original Message -------- From: Brian Meade <[email protected]> Sent: Monday, September 14, 2015 03:49 PM To: [email protected] Subject: [cisco-voip] MRA (Collaboration Edge) Intrusion Protection >Is anyone else having issues with the "HTTP proxy protocol violation" >automated detection feature or Expressway? > >I've got over 10,000 hits on this built-in rule and it seems to be blocking >some legitimate logins via Jabber. > >It looks like this in the event log: >2015-09-11T21:05:09-04:00 sh[1195]: Event="Intrusion Protection" >Src-ip="X.X.X.X" Detail="Collaboration Edge HTTP Intrusion Protection >blocking X.X.X.X" Level="INFO" UTCTime="2015/09/12-01:05:09" >2015-09-11T21:05:09-04:00 traffic_server[24581]: Event="Sending HTTP error >response" Status="429" Reason="Unknown Status" Dst-ip="X.X.X.X" >Dst-port="52940" UTCTime="2015-09-12 01:05:09,151" > >It looks like this in the Jabber log: >2015-09-11 17:09:15,746 INFO [0x00000dc0] >[ls\src\http\BasicHttpClientImpl.cpp(399)] [csf.httpclient] >[csf::http::executeImpl] - *-----* HTTP response code 0 for request #2 to >https://myexpressway.client.com:8443/bG9naWNub3cuY29t/get_edge_config?service_name=_cisco-uds&service_name=_cuplogin >2015-09-11 17:09:15,746 ERROR [0x00000dc0] >[ls\src\http\BasicHttpClientImpl.cpp(404)] [csf.httpclient] >[csf::http::executeImpl] - There was an issue performing the call to >curl_easy_perform for request #2: CONNECTION_TIMEOUT_ERROR > >It looks like this in the detailed expressway logging: >2015-09-11T11:12:06-04:00 atlitexpe1 UTCTime="2015-09-11 15:12:06,146" >Event="System Configuration Changed" Node="[email protected]" >PID="<0.3251.0>" Detail="xconfiguration fail2banJailStatus uuid >12f52e25-4df6-4fd3-9697-621d9de3a796 jail: http-ce-intrusion total_fails - >changed from: 202411 to: 202416" > > >Anyone else seeing issues like this?
