If you question the superiority of the relational model... you're doing it wrong.

comment No outgoing network after Amazon restarted EC2 instances
Since you have a 192.168 address, this suggests this is a VPC instance, which suggests you also have a NAT instance providing Internet access service for this instance. If so, you need to troubleshoot why that machine, perhaps, isn't doing what it should. Are you familiar with the concept I'm discussing? Did you build the NAT instance yourself, or are you using the stock AWS image for it?

comment Amazon EC2 Instance Continually Loses Connectivity
Well, not quite "obviously" if the status checks are still passing. You're saying all of the Cloudwatch metrics (in the AWS web console) stop updating?

comment Amazon EC2 Instance Continually Loses Connectivity
How do CPU utilization and memory look, in the instance metrics in the console? Is this a micro instance?

comment Grant net_privaddr privileges on a AWS server
It sounds like you are trying to apply Solaris or BSD concepts to Linux. You should probably edit this question to ask how to solve the actual problem you are having, rather than how to do what is probably not the thing that needs to be done in order to solve the underlying problem, which you haven't mentioned.

comment Windows 8.1 — PPTP VPN connection dies after a minute or two
Try (as a test) ping -t (something across the vpn) and see if keeping active traffic is really the differentiator. I have left Win 7 to Linux PPTP connected and largely idle for weeks without issue, so it's hard to say that a different protocol would necessarily fix the underlying issue. EC2's network infrastructure, like many others, will eventually "forget" very idle connections, but not in a couple of minutes.

Please check the actual mysql error log. Often this is found in the directory /var/log/mysql.

comment invalid default value in SQL export
Sounds like maybe your destination server is an older version of MySQL that doesn't support current_timestamp as a default for datetime columns... what response do you get from SELECT @@VERSION; on both servers...?

comment Tar a very large file directly to a drive
You say S3 is "mounted" - so it sounds like you are using s3fs -- and it seems likely that s3fs is what's using temp files, not tar and cp. If you enabled the disk cache in s3fs, the obvious first thing to try would be disabling it. If not, then you need a different approach, something that can stream the tarball directly to s3 rather than using s3fs, if s3fs always needs temp files, even with the cache disabled. Or, mount an EBS volume or another ephemeral disk if you have one, for the temp files to live on while you need them.

comment Working on Amazon EC2 not smooth - expectations or setting issue?
It should of course be noted that the cited article has a clear conflict of interest. As a wholly satisfied AWS user, I'm completely unimpressed by such transparent whining.

comment Why can't I access MySQL server with port forward rule in router?
The "error 2003" from MySQL also gives a numeric code in parentheses, which provides a platform specific reason for the failed connection. What code do you get when you try to connect?

Which "ROOT" are you talking about, and how did you "copy" it?

comment SUPER,REPLICATION CLIENT prev to external MySQL user
So you're saying that the remote user logs in, gets that response to SHOW GRANTS;, and then immediately can't run SHOW SLAVE STATUS;?
