Hi all. Does anybody have any examples for using the src_vipa command? I have been rooting around, trying to find this on the web and have had no luck. We want to use this to implement an HA environment for our HTTP/WAS applications. Thanx in advance for any assistance.
Hi Jack, I've been on holiday so I'm not sure how far you have progressed with you question....... I would just say that src_vipa.sh uses the library preload feature which means it has limitations. For example any programs that run as root (or via setuid-root) will ignore the library preload and hence the source IP will not be set. This means that simple commands like "ping" will not have the source IP set which can be very confusing if you are attempting to use ping to verify your setup ;-) Other problems can occur if you try to use NFS mounts via the VIPA. To get around most of these problems you have a couple of basic options: 1) Statically use the ip route add xxxxx src xxxxx 2) Dynamically via quagga/ospf use the route-map command to set the src. Hope that helps a little, I don't work with WAS very much, but do manage SAP HA networks. mark ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
