Flood, pestilence and technology

Well the UK has been hit by severe rainfalls again, resulting in massive flooding and a few unfortunate accidents

my cosy little home normally manages to escape the raging torrents of flood water. this time i get taken out by an indirect event. Between 19:25 and 20:30 last night most of Abbeymead in gloucester has no power. My UPS stayed up for 35 mins and then gave up, my friends UPS , (where my main internet connection comes in) lasted 45 minutes and then shut everything down !

so along come the power and everything starts to boot back up, when the firewall goes, kernal panic follwed by bad sector and then just to finish it off disk I/O error, and never worked again.
Out of all the things on my rather large home network to fail, it would the box with no regular backups or hot spare
Some mild panic ensued as all my SMTP emails and a few??business associates??fallback SMTP goes via this firewall !!!!!!!!!!!!

The firewall was, note the past tense, running smoothwall corp 3, with smoothhost , rule and guardian modules
corp 3 is over 3 years old, do i still have the media, do i have the licence key, do we have a spare HDD.

Fortunatly my slight over zealous, dont delete anything nature plumped up the software images, and the licence key
My friend the fitted a new hard disk, and installed the basic firewall software and connected it to our green network,

Then comes the fun part, re-config the beast, so working between trying to get the kids ready for school this morning, i managed to re-key all of the PAT and NAT forwarding rules , phew,

??NOTE to self for future reference, ??GHOST the disk , just in case

Panorama Wi-fi

Well what can i say, just watched panorama and there scare mongering attack on WiFi etc
Dont get me wrong, there could always be a small risk, but the manor in which is is presented was nothing more than scare mongering…. (does make me wonder about the presetation of the scientology investigation)
Using generic RF level meters to look for RF radiation is complete waste of space, one guy had the right approach using a spectrum analyser, and comparing the Levels at particular frequencies, but did nothing to explain the graphs

Mobile phone and Wifi frequencies at over an octave apart, and will have very different effects and interferance patterns

Picture this, typically only one frequancies will break any particular glass, a sound wave lass than an octave either way, will not break the glass. Therefore any PROVEN findings from specific mobile phone invetsigation, MAY NOT apply to other mobile phone network technologies, let alone WiFi !!!!

WordPress Epidemic

Following on from a minor outbreak of worpress during my day job

I have now been asked to look at setting up a proper and formal blog platform using wordpress with AD integration ….
Enter wpLDAP ….. sorted

Horay for common sense.

Playing the Marketing call centers at their own game

By adding a Linksys spa-3102 to my existing TRIXBOX iPBX which is have running under VMWare server on windows 2003, i am now able to route inbound call based on caller id or lack there of (or the number that was dialed if I add some free SIP trunks from sipgate) to any extention in the house or group, but even better a fully featured IVR, lets see how the marketing tossers like a bit of that

I just found this too Littlewoods bombards man by phone

In the USA there is a decent computer and electronics??chain called FRYS,

So I felt duty bound to buy an item or two, hey, wont get caught sneaking it past the wife, as i can leave the boxes etc in the US………… 😉

So I phone the wife up and ask if my coporate credit card statement had arrived yet? and could she fax it to me,
After much rustling on the phone , I hear, “YEP got it, …….. no, oops sorry !… this is your peronal one……. ” followed by
“WHAT HAVE YOU BEEN BUYING IN FRYS ????”

🙁 DOH !!! 🙁

Technology at its best

After much google,ing and faffing, i have managed to

  • get my SIP softphone (VOIP) to connect to my asterisk box at home with out the use of a VPN
  • Get RPC over HTTP email to work
  • setup WEBDAV over SSL access to my file server

So I no longer need the VPN to do normal networky stuff to home, the only reason i need the VPN now is to trick Sky Anytime into thinking I am in the UK, and that is only the gui client, the peer to peer service does not give a stuff, so once i have requested the video, i can drop the VPN !

I am Glad i am NOT paying to the t-mobile WiFi usage !!

Vista, Compaq R4065EA and a card reader

Though I would try Vista on my laptop, nothing is ever simple

NEW hard disk and some more RAM (US prices are Sooo reasonable)

install was great, than came the fun
Sky Anytime requires admin rights to run (something which Vista does not give away lightly), i then had to phone sky to tell them i had rebuilt my PC, as te ANYTIME software thought it was a different machine, the Sky Anytime helpdesk was surprisingly effecient at sorting that out !

Then there was device drivers, the modem, Card reader and web cam do not seem to come with bundled drivers, Compaq support site says they wont support Vista on ths laptop, but then they dont do 64 bit drivers for XP for it either (what is the fucking point is selling a 64 bit laptop without 64 bit OS and Drivers)
so “google is my friend” and discovered a few other laptops with the SAME crad reader chip set, and managed to down load a driver from herehttp://www.sagernotebook.com/pages/notebooks/download.cfm?ProductType=5750

SORTED…

not going to bother with the modem, have not used one in years !

the WEBCAM however is a different story

Just a quick note to compare and contast two different Virtual Computer tehnologies

VMWare, One free package which will support many OS in a host machine, regardless of host OS
Microsoft, Virtual PC or Server, which depends on the Host OS NOT the Guest !
{EDIT} they will both run on any Os, the difference seems to be if you wnt it to run in th ebackground or forground, in the forgrond it has seemless access to the console, in te background it has a crap web based thingy.

VMWare Server (FREE) allow you to MAP USB ports
Microsoft Virtual PC, does not, or at least i cont find out how

VMware has a simple P2V (physical to Virtual) toolset
Microsoft seem to want to mak it difficult to download their P2v suite

Well, its me again, sat in my hotel room in Seattle

due ti the fact i have NO Sci-Fi channel on the TV in my room, I thought i woudl re visit Sky Anytime, formerly known as Sky by Broadband

I??dont really like it because it is a peer to peer system and therefore a bandwidth hogger (waster if you hav to pay for it)
but he i am deperate for some decent TV, non o fthe jerry springer format stuff, which is all yoiu sem to get on network TV in Seattle

Attempt 1, Based on you IP address you are not in the UK, SOD OFF
Attempt 2, VPN to home, sorted donload starts, but how slow, competrting for bandwitdh on the 256Kb/s side of the ADSL
Attempt 3, VPN to a mates office, he has 1.5 Meg SDSL??

SORTED, still slow, but at least i get to download and watch some decent TV

Imagine this,??Maplins, PCWorld, Farnell and RS Components buy an old ASDA store, and setup a BIG retail outlet….

Then you wold have FRYS,

I have been to FRYS electronics store on Renton near seattle,
The place should come with a health warning for your bank account….??

from resistors??to??PCs to PC spares to HiFi to TV to Books, if it can be deemed a techie thing it was there !
