comment Use puppet to change the IP address on the nodes
Both will work but the better way is to use a template and a parametrized class. See docs.puppetlabs.com/learning/modules2.html

comment Batch MySql script stopped with error “(104)Connection reset by peer”
You could probably get away with beefing up the server but a web interface was not designed for batch processing. As your import job grows so must your server. Take a look at ux.stackexchange.com/questions/3170/… for ideas on how you can shoehorn it in.

comment Scalable Multi Server E-mail setup using Linux/Dovecot
I don't have a proven answer but I'd investigate using dovecot's dsync replication with haproxy in front of postfix (using the proxy protocol so you get the client IP for spam filtering) and also haproxy in front of roundcube. All the mail goes to every server so I'm not sure it "scales."

comment Scalable Multi Server E-mail setup using Linux/Dovecot
By what process did you determine using Postfix, Dovecot, and roundcube is the best way to meet the requirements? I would have tended towards recommending gmail or exchange online because being a postmaster sucks.

comment Chrooted user can't login with SSH
Those are not the correct permissions. ChrootDirectory: "Specifies the pathname of a directory to chroot(2) to after authentication. All components of the pathname must be root-owned directories that are not writable by any other user or group."

comment How to monitor socket connection usage and exhaustion on a server?
That doesn't indicate sockets were exhausted. It could be your app can't process the connections fast enough and only so many TCP connections can be backlogged (/proc/sys/net/ipv4/tcp_max_syn_backlog), which has nothing to do with socket exhaustion.

comment Getting Java Version in bash script results are blank
I'm not sure what you are trying to say. Every invocation of bash has an associated environment that contains variables. You define JAVA_HOME in the environment of one invocation of bash and attempt to use it in a different environment (that of the 2nd invocation of bash).
