Tonights Maintenance

Tonights maintenance didn’t go entirely smooth.  Machines are having problem syncing time with ntp and ntpdate when they come up.  It’s a flaky intermittent weirdness that is difficult to troubleshoot.

As a consequence I didn’t get the backup of the web server done, so I’m going to do that Sunday morning shortly after midnight.

I also will be available after approximately 11am Saturday morning owing to how long this took and how late I’m getting to bed (which will be just after this post).

Maintenance Saturday Morning – January 4th 00:05AM – 1AM

Early Saturday morning, just after midnight, I will be performing some system maintenance.

First will be a reboot of the main file server to test the shutdown and start-up scripts to be sure I’ve got all the bugs worked out.  This will take everything down briefly, but if successful, that is to say if I’ve killed all the bugs in the shutdown and start-up scripts, this will only take about five minutes.

This will be followed by about 15 minutes of downtime for the web server for imaging to make sure the backup image has the current 2.4.7 Apache, the current 7.25 version of Drupal, and some other recent updates to our website.

Visual Access to Shell

Our instructions for visual access use a No Machine product called 3.5 Client.  Unfortunately, this is no longer available.

Nx 4.0 Player DOES WORK with our service although it can take 4 or 5 attempts typically to get a connection and setup is more complex.  I am working on a new set of instructions of use with it.

Also, on Windows and Linux, OpenNX and X2Go also work with our system although X2Go sometimes doesn’t play nice with other applicaitons.  On McIntosh systems, these products seem to have key mapping issues.

An alternative to No Machine (NX) 4.0 Player for Mac is a VNC client.  I recommend Chicken VNC (this is a derivative of Chicken of the VNC and is better because it supports tunneling through ssh).

VNC does not compress as efficiently as NX but if you have a broadband connection, the response is satisfactory.  X2Go is new and somewhat spotty still, but when it does work, it also provides sound (but that also is intermittent).

For Windows, TightVNC performs well but is insecure since everything passes plain-text unless you setup an ssh tunnel using putty or other windows ssh client.   The risks with TightVNC are essentially the same as those of telnet or rlogin, everything is passed over the Internet plain-text.

I’m working on support pages for these newer products and always looking for something more solid, but on the bleeding edge, that’s sometimes how things are.

New Years Hours

I will not be available at 9AM on New Years Day.

I will be available between 12 noon – 6pm and after 6pm intermittently.  If you call after 6pm, leave a message and I will return your call.

So if you need help with something or want to extend your subscription, I will be here in the afternoon and evening to take your calls.

Bogus e-mail: Your Password Will Expire in 3 Days

If you see e-mail that says your password will expire in three days, ignore it.  This is a phishing scam that is attempting to get your login credentials here.  Do not click on the link, do not fill in your login and password.

This is entirely different than the notices we send out regarding account expiration dates.
