asked How do you build redundant Linux servers, such that clients don't lose connections on failure?

comment How to make SCP on Linux output “success” to stdout instead of stderr?
Actually, I think there is a 2>&1 missing just before the pipe. The file redirection already swallows all stdout output, so all that is left is stderr, but | does not care about it, so we have to move stderr to stdout, before sending it through the pipe.

It's a "security thing"; the DB server can connect out to LOCAL-SERVER, but not the other way around. So I have to push the files, instead of pulling them.

comment What is a realistic average time difference between servers in the same LAN?
No. And I cannot do that anymore since that cluster was "retired".

comment What is a realistic average time difference between servers in the same LAN?
Yes, milliseconds, not microseconds. And I measure it as I said in my comment to @Gregory. By comparing the local time to the "sent time" of the event I receive. If the sent time is older, I cannot say if it is clock drift or network latency. But if it is in the future, than I know that the clock of the sender is ahead by far.

comment What is a realistic average time difference between servers in the same LAN?
I have a central "loadbalancer" that receives messages from all machines regularly. And it can display the timestamp value of the events it received from the other machines. When an event arrive 100ms before it was sent then I know that the clocks have at least 100ms differences, probably a lot more.

The problem was on the hardware cluster, but it did get worst on VMWare.

comment What is the Ubuntu command that allows you to specify what you will use the server for?
Thank you @root45 I stand corrected. I didn't even know I could change the "selected answer", but that's a good thing in this case.

I swear when I saw you both that you were first, but the link that root45 showed me points to adaptr being in fact the first. Something like this never happened to me before. Either a glitch, or I somehow got it wrong. Sorry for the confusion.
