Redirect connection

[peterchu]

I have two UX servers ( eg. Server A , Server B ) , the users use Netterm as emulator to telnet to connect to these servers , each server have assigned a dedicated IP address ( eg. Server A --> 192.168.1.1 , Server B --> 192.168.1.2 ) , now if a user want to connect Server A , he need to telnet to the Server A's IP address ( 192.168.1.1 ) .
I want to ask if Server A failure suddenly and a user want to connect to Server A , is it possible to redirect the connection from Server A to Server B ( from 192.168.1.1 to 192.168.1.2 ) ? thx

eg. assume Server A and Server has the same login password and same data so user can login either server

you should cluster these two machines using HP's MC Service Guard.

Peter,
As Harry suggested you should cluster the systems.

Harry,
Please let me know some detail on this

Using the above is it possible to fail over user connections dynamically ? I know for sure that this cannot be done on many clusters without employing some products

No, the users will probably have to re-telnet in. It largely depends upon the application being able to failover, and typically if a user is telnet'ing in then its probably not a "tiered" application allowing failovers.

Thus, the big answer is NO. They will have to login again.

Peter,
So the answer to your initial question of failing over user connections is NO.

Application fail-over is possible, depending on the application types but user connections cannot be failed over dynamically from one server to another. This means that the users who were on Server 1 that crashed have to relogin into Server 2 that is running
