gateway failover.

Wed Nov 11 04:03:17 UTC 1998

i'm looking for pointers to any resources for doing failover on
solaris boxes. i have an environment in which i'd like a pool of 
servers to use one of two solaris boxes as their gateway, the other
box being in hot standby until a failure of the primary box occurs, 
at which time it would failover. 

something like HSRP for unix would work nicely, though i've not found 
anything similar, except for IRDP (rfc1285), however it doesnt seem to 
be supported by anyone, in so far as i've been able to tell. 

i'm aware of commercial solutions, but i'm hoping to find something 
in the public domain as most of them are overkill and/or expensive. 

i'd like to avoid doing something with gated/ospf (or another suitably
featured routing daemon/protocol), as the environment may include NT, 
95, and other boxes that dont easily listen to any sufficiently useful 
routing protocol, as far as i know. 

i'm open to just about any suggestion, including an L2 solution, 
except for something that would depend on clientside software, 
because of the OS limitations. 

respond privately, and i'll summarize to the list if necessary.
