Environment

NetIQ Access Manager 4.0
NetIQ Access Manager 4.0.1
NetIQ Access Manager 4.0.1 HF1
NetIQ Access Manager 4.1

Situation

  • NetIQ Access Gateway Appliance has been configured to retrieve security patches as documented in section: "Installing or Updating Security Patches for Access Manager Appliance"

  • all security patches have been installed running: "zypper refs", "zypper up"

  • the loopback interface got lost after adding / removing an IP address and rebooting the appliance

Resolution

  • This issue has been fixed with NAM 4.0.2 and NAM 4.1.1

  • Workaround:

    • re-create the loopback interface config file "/etc/sysconfig/network/ifcfg-lo" either by copying it from another SLES based system or another Access Gateway Appliance.

    • create a backup of the re-created loopback config file: "/etc/sysconfig/network/ifcfg-lo" like "/etc/sysconfig/network/lo.backup"

    • edit the "/opt/novell/devman/jcc/scripts/postsysconfig.sh" and add the following entry:
      "cp /etc/sysconfig/network/lo.backup /etc/sysconfig/network/ifcfg-lo". This script will be executed executed after all other system configurations are done, like dns, routes, network, etc.
