NAME
netdiff - A simple script to diff a file or a directory of two hosts
over the network.
This is very helpful if you want to find out any difference of these two
hosts.
SYNOPSYS
netdiff HOSTNAME PATH [PORT] [ADDITIONAL DIFF OPTS]
USAGE
Cluster-SSH into two hosts at the same time and run on both hosts the
same (simultaneous):
netdiff HOSTNAME PATH
Where HOSTNAME can be the hostname of the first or the second host.
Depending on this the script will decide to be the client or the server
role.
And where PATH musst be a full qualified path to a file or a directory.
Netdiff transfers everything in PATH (recursively and encrypted via
OpenSSL/AES) to the other host and computes a diff of it.
If no port is specified the default port will be used, which is defined
in
/etc/default/netdiff
EXAMPLE
A common use case is to find out the differences of the PAM
configuration. On most systems the PAM configuration is spread into
several small configuration files which are hard to compare by hand
between two hosts.
Given two hosts one.example.com and two.example.com. Just run this
command on both hosts:
netdiff one.example.com /etc/pam.d
The same affect, but the other way around would be the following
command:
netdiff two.example.com /etc/pam.d
