I have a suite of scripts that ssh to remote servers within a cluster and run some tests. This is done from a central server so that all of the test results can be captured in one location.
Problem is I now have 509 tests and the number is growing. The scripts work by establishing a fresh ssh connection for each test, so things are slowing down.
I suspect it would be a lot more sensible to establish a tunnel at the start of the run and keep it open until I have run all of the tests ...
Problem is I don't know how I could call the remote tests (bash scripts) via the tunnel.

Two question here, but it's only one on the protocol point of view.
If two persons use the same key to connect to a SSH server is there a risk they can decipher the other tunnel. In other terms is that less safe than if they have two separate keys.

I have a Java web app on machine (X) that needs to talk to an LDAP server (Y) on :636, but the LDAP server is only accessible on a particular network.

How can I tunnel so that X can... (2 Replies)

x11perfcomp
X11PERFCOMP(1) General Commands Manual X11PERFCOMP(1)NAME
x11perfcomp - X11 server performance comparison program
SYNTAX
x11perfcomp [ -r | -ro ] [ -l label_file ] files
DESCRIPTION
The x11perfcomp program merges the output of several x11perf(1) runs into a nice tabular format. It takes the results in each file, fills
in any missing test results if necessary, and for each test shows the objects/second rate of each server. If invoked with the -r or -ro
options, it shows the relative performance of each server to the first server.
Normally, x11perfcomp uses the first file specified to determine which specific tests it should report on. Some (non-DEC :) servers may
fail to perform all tests. In this case, x11perfcomp automatically substitutes in a rate of 0.0 objects/second. Since the first file
determines which tests to report on, this file must contain a superset of the tests reported in the other files, else x11perfcomp will
fail.
You can provide an explicit list of tests to report on by using the -l switch to specify a file of labels. You can create a label file by
using the -label option in x11perf.
OPTIONS
x11perfcomp accepts the options listed below:
-r Specifies that the output should also include relative server performance.
-ro Specifies that the output should include only relative server performance.
-l label_file Specifies a label file to use.
X DEFAULTS
There are no X defaults used by this program.

Mark Moraes wrote the original scripts to compare servers.
Joel McCormack just munged them together a bit.
