Remote power control of PC, on/off, by dial-up modem or by IP
I'd like to be able to leave a PC in a remote location knowing I can
get back control if the worst happens and it locks up. Basically I may want to power cycle the PC so am looking for a device which * Can turn 13A mains sockets on and off * Can be accessed remotely - by phone line or modem - by IP address * Is secure - password for phone line, more for IP-based (to stop someone else getting access) I also want to tie the PC to a UPS. Not sure if the two functions can be combined. Anyone else been down this road or have some ideas? -- TIA, James |

I use these: http://www.quasarelectronics.com/3140.htm If one of the things you might want to restart is the router, using IP addresses *after* the router is not that good an idea. Note that the unit has 4 independent, isolated, relay contact changeover sets. So you can use one to switch the supply going from UPS to computer and others to switch normal mains (non-ups) supplies.The relays are rated at 5A, so one can switch the supply to a fair few routers/switches/modems/etc. Alternatively, you can use one relay contact set to operate the computer "reset button" (eg switch 5v) - leaving the computer normally on and running. with maybe a different relay doing the "BRS" job and switching the computer supply - if the reset didn't do the job.. -- Sue |

These look great - especially being much less costly than the Web ones - but I've just realised I'll need and don't have a way for them to share a phone line. The other device on the line should answer first to take normal calls so I guess that means I need a way to tell the other device not to answer for 20 seconds or so.... Thanks for the pointer. -- James |

I had a similar problem - in wanting to control more than 4 switches with one phone line. I went for a cheap pabx on the line. Although the one I got was second hand, even new ones are pretty cheap (eg ebay item 230228084074 20GBP, delivered*). *I don't know if that one will do the job, btw - it is just an example. Mine allows me to dial the main number followed by the extension number, then send commands to and from that particular controller. Using a small pabx would also allow a fax, a modem, whatever, to sit on different extensions... -- Sue |

The web page for the 4-channel switcher does say "This product is _not_ compatible with PABX systems, digital phone systems or phone systems outside the UK." but it sounds like you have one or more units working as extensions off a PABX. Is that right? Maybe it's just extension-to-extension calls that fail to control the switcher. |

Have you considered turning it on with a magic packet? Wake On LAN? But turning it off may be an issue. You can boot into the OS and access it remotely from there and shut it down, but if you cannot get that far in, then that is not an option.. . OTOH, if things are "that bad" that you cannot get that far in, then there may not be much you can do from it remotely anyway. |

Read this: http://www.crosbycomms.co.uk/technic...pbxsystems.php The unit's interface is that of a standard 2 wire POTS telephone. Any PABX that won't accept POTS phones as extensions won't work with it. They also won't work with standard fax machines or standard modems. However, most SBHO PABX *do* work with standard POTS phones and will be fine. The ebay item I quoted *should* be fine. It passes DTMF signals through to the extensions and takes standard POTS phones as extensions. However, I don't now either that particular model and have never bought from that particular seller - so hence the *should* and my reservation about it working in my PP. Just as the web site put in the PABX warnings. I bought second hand Panasonic equipment - basically becuase I tend to think a second-hand unit from a recognised manufacturer is going to be more reliable than a new unit from an unkonwn supplier.. -- Sue |
