I am using UCARP on two FreeBS highly available apache virtual hosts.&nb work very well except that occasionally one webserv inaccessable from outside it's subnet. I have narrowed an arp issue. When a UCARP IP becomes unavailable. start a constant ping to it from my machine which lives on a d ifferent subnet, all requests timeout. I log into the cisco router
th view th listed for that clear the arp cache table update correctly aft the webserver is again accessible
So, I have come up with a few include:
1.&nbs that outages a problably stress th about cisco devices so think that this is a bad th cache arp entries on just the currently consists of about 25 hosts all?
2. Run an ANT task to task can become part of the UCARP solution but security is a concern.
3. Find a way to make the FreeBSD nodes produce more than usual gratuitous arp packets or add a line to do only that in the UCARP
scripts. may be able sometimes d Could it be a p properly?
Any input at all is greatly appreciated.
