I could not locate the manufacture at all. I lost communication with my home server and started worrying if my house had caught a fire or a group of thieves had taken away everything.

The first unit I got was dead but a replacement worked fine. I guess the power supply circuit is dead.

IPPOWER - Automatic Power-Cycler

The second was to build a scheme to restart a dead network device automatically. After coming back home I found there was possibly a power outage for the whole house because many appliances had blinking clock display.

I tried to contact the eBay vendor Firmeare purchased the unit from with no luck. I could not locate the manufacture at all. The first measure was to subscribe to an external secondary SMTP server for my own domain, that is primarily served by my in-house SMTP server, in order to prevent incoming mail from bouncing in case my own SMPT server is not accessible.

The exact cause of the lock-ups is unknown; it may be a firmware bug or some kind of glitch on the telephone line though I have installed an inline filter on its telco line. Secondly, create a special user account "ippower" on the Linux host.

I disassembled the box to locate the failure source, say just a blown fuse or a burned resister, but I was unsuccessful. It is easily configurable. A simple web interface can individually turn on and off its four Flrmware outlets. I created a new device file that describes the device dependent functionality of the Web Power device and modified all port files to point to the new device file. Unfortunately, I have little experience with other installations such as Suse and Debian so that I cannot provide good support for them.

Two or three failures a year may not sound significant, but, as Murphy's law tells, they usually happen at the worst times. All times are in number of seconds.

Another major distributor of the IP-Power advised me to update the unit's firmware through its serial port although I had told them the unit's hardware had seemed dead. So, I decided to prepare precautions to reduce the risk. Last summer it happened when my whole family was on vacation in a foreign country for two weeks. This should reduce the risk of unwanted hacks taking advantage of super user script processes. There are two versions, once of the U. A port file needs the following shell variables defined: It also has a simple timer-driven power control so that, once a timer is set via the web interface, an outlet can be automatically turned off and on without direct control by a host computer, though my IPPOWER project does not use this feature.

The document has serious errors in this area and below is the correct URLs that I verifeied to work. A few months after I wrote the first version of this document, my IP-Power died; it started to keep beeping and power-cycling in a few second interval and of course it no longer responded to network accesses.

Next, unzip the distribution file into a work firnware and edit a few file for local configuration. The Web Power works in a very similar way to the IP-Power; only the URLs had to be changed and this was within my original preparation for portablity of my code.

The IP-Power is a very simple but useful device. Firstly, set up the IP-Power for it networking connection and account management user name and password.

Well, not everything goes well.
