ExOS 7.4.2 Release Notes

Author: Luis Fernandes
NOTE: Version 7.4.2 introduces a mechanism that better handles DDoS attacks coming from the WAN or from malicious software, preventing the appliance from consuming too much memory. In consequence, the TCP Health report has eliminated the ÒIgnored ConnectionsÓ count. Nevertheless, Ignored Connections for real time traffic is still available.
Supported upgrade versions:

¥ 7.0.0, 7.0.1, 7.0.1u1, 7.0.2, 7.0.2u1, 7.0.3, 7.0.3u1 and 7.4.1
¥ 6.4.6, 6.4.7

Upgrade Path:
  • The supported upgrade path from 6.x is to upgrade to 6.4.3 or later first. Then upgrade to 7.0.0.
  • The upgrade from 6.4.3 may take longer than normal due to the database upgrade that takes place.
  • v7.x will only accelerate with peers running 6.4.3 and later due to a change to the Exinda internal protocols. If you are installing v7.x into an x800 estate, the best approach is to upgrade your core box to 6.4.3 and then install v7 on one or more branch offices.
  • This allows all the existing appliances to accelerate to the core appliance and allows the v7 appliance(s) to accelerate to the core box running 6.4.3
  • This version was released with a new set of virtual images that are running 7.4.1 by default. If your environment already contains configured virtual machines running an older version, please upgrade to 6.4.3 first and follow the upgrade path above described.
Platforms:
  • 2061, 3062, 4010, 4061, 4062, 6060, 6062, 8060, 8062, 10060, 10062, 10063, 12063, Virtual

Bug Fixes and Minor Improvements:
  • [D-04410] Solved classification issue where Proxy traffic is diagnosed as BitTorrent
  • [D-03452] Fixed issue where DDoS attacks coming to the network severely affect ExindaÕs memory utilization.
  • [D-05106] Solved issue where the appliance was not processing and hence dropping Kerberos authentication packets
  • [D-05125] Fixed classification issue where Netflix was being misclassified as HTTPS
  • [D-05137] Solved an issue where exinda was dropping certain OpenVPN packets when these are being transmitted on a GRE tunnel with IP packets that have been previously fragmented
  • [D-05104] Fixed a report representation issue where traffic falling under the default Auto Catch-All policy was not being reported on the Control graphs.
Known Issues:
  • [D-04189] In certain scenarios, accelerating SMB connections can result in slow file transfers.
  • [D-03974] Edge Cache process can trigger a condition that makes it reboot
  • [D-02086] Acceleration is not supported between sites that are separated by a Firewall/Router that is performing NAT overload.
  • [D-04861] Users are not able to access the WebUI with a username that starts with a zero Ò0Ó
  • [B-06114] Inbound QoS for HTTP traffic hitting the Edge Cache engine can only be controlled by the policy set for the Web application group or the HTTP application object
  • [D-04963] Users with ÒMonitorÓ only capabilities can start/stop the optimizer.
  • [D-06081] Some CA certificates are displayed as ÒExpiredÓ (Configuration > System > Certificates > CA Certificates). This, however, will not affect the appliance performance.
  • [B-06115] APS values are normalized to 1024 bit of packet-size, so applications that use very small-size packets like Citrix and RDP are not recommended to be measured using our APS feature as the values will be much higher than the real ones.
  • [D-04111] Edge Cache does not work for YouTube in Chrome browser. Work Around: Add Ò--use-spdy=off --use-system-sslÓ to Chrome shortcut. For example: ÒC:\Program Files (x86)\Google\Chrome\Application\chrome.exe --use-spdy=off --use-system-sslÓ For group policy of changing Chrome shortcut, please refer to http://blogs.technet.com/b/askds/archive/2014/02/17/adding-shortcuts-on-desktop-using-group-policy-preferences-in-windows-8-and-windows-8-1.aspx
