Bletchley Park
by Richard Lewis 17 May '06

17 May '06

Hello ALUG, Just before we all left last night, I remembered that a little while ago on IRC mention had been made of a possible trip to Bletchley Park. Now that the weather has taken a turn for the better, I wonder if anyone still thinks this may be fun? There's a fairly informative website at: http://www.bletchleypark.org.uk/ They do group weekend visits between 10:30 and 17:00 for 8.00 GBP per head for 20+ people and allow (possibly require) booking. Maps and various route planning info: http://www.bletchleypark.org.uk/content/visit/findus.rhtm For those of us in Norwich, the train journey is not all that good: AFAICT you need to go through London (Liverpool St -> Euston) and it takes about 3:30 hours. By road it will probably take about 3 hours (A11, through Thetford, Cambridge, A428 through Bedford to Milton Keynes). Any thoughts?

Thanks, Dave (Gilbert) for confirming that firefox can be flaky, and David (Johnson) for the above. Yes, you were right! Disabling pop-up blocking solves the problem. The reason http://www.shop.bt.com bombs right out is that you get one of those smarmy "special offers and competitions" popups while the top page is still loading. You're not meant to miss it! (Which leads me to wonder: can a website send a popup which might force a popup blocker to segfault? Good way to get you to turn off the blocker ... ). Thanks, and all best wishes, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 17-May-06 Time: 14:21:46 ------------------------------ XFMail ------------------------------

Segfaults with Firefox-1.0
by Ted.Harding＠nessie.mcc.ac.uk 17 May '06

17 May '06

Hi Folks, I've been noticing a tendency for my Firefox-1.0 to segfault when accessing certain sites. It may not be Firefox of course, but a possible (e.g.) RAM weakness or something else hardware related. The message to the terminal is always run-mozilla.sh: line 451: 2894 Segmentation fault "$prog" ${1+"$@"} which is a line in the startup-script. One site which seems to trigger it every time is http://www.shop.bt.com If anyone else would like to try this and report results, I'd be obliged. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 17-May-06 Time: 13:53:05 ------------------------------ XFMail ------------------------------

Encryption
by Richard Brooklyn 17 May '06

17 May '06

The other day, I got myself a new laptop, all is well and good with it running Ubuntu Dapper. I saw a article in Linux Format about encrypting the hard drive. I did follow it closely, but was unable to make it work. This was probably due to me trying to encrypt / instead of something like /home so I gave up. But I do wish to try again. I've just downloaded OpenSUSE 10.1, which gives the option to encrypt during the installation. It [the OpenSUSE install] seems to work pretty well, especially if you're just a single user, you can set a nice long password for /home, and it will ask for the passphrase during start-up, which I was very happy with. But it's got me wondering. Exactly how secure is this? Let's say I can use either OpenSUSE 10.1 or Ubuntu Dapper .. Say someone steals my laptop. Is it possible they will ever get hold of my data (ie. decrypt it)? Should I be encrypting more than just /home? (I was thinking about /tmp -- but I don't want to keep entering in loads of passphrases on every boot). Is it possible to encrypt / at all? That would be very handy, then it's just one passphrase, and I know that everything is secure, but I know I can expect a performance hit with this (which is not important). Cheers, Richard.

Weekly IRC reminder
by Brett Parker 15 May '06

15 May '06

This is the automated ALUG IRC meeting reminder sent to remind you that there is an IRC meeting tonight (Monday) at 8.00pm. Historically, these used to be the only time a lot of us would be about, now the channel has some usual faces that are there most of the time (except at silly o'clock, when we might be sleeping, or on the second thursday of the month, where we might be drinking in the Reindeer), so don't feel limited to visit during this time, come visit us when ever you feel like it! The meeting takes place on the irc server irc.alug.org.uk in the #alug channel. Most IRC clients should allow you to get there with the commands "/server irc.alug.org.uk" and "/join #alug". Popular IRC clients include xchat, irssi and EPIC on Unix, and Mirc under windows. Here are some links to help you get started with irc. Unix http://www.xchat.org/ http://www.irssi.org/ http://www.epicsol.org/ Windows http://www.mirc.com (loads of help with irc for newbies!)

Heeeelp! My display system is rather messed up.
by Barry Samuels 14 May '06

14 May '06

First an apology. This message may appear twice because I forgot to set my identity in the mailer so the first one may not make it. I'm running Debian Testing (Etch). I've been waiting 6 months to do an update because K3b was missing from the distribution for about that time and it has just reappeared. So I did the update and then discovered that my mga drivers from Matrox no longer work. I see that other people had the same problem. There is an MGA driver package listed but it depends on the xserver-xorg-core package which isn't in the distribution (this is getting ridiculous). Matrox don't (yet?) provide a driver for xorg 6.9 but after a search I found that someone had modified the latest Matrox driver to suit 6.9 which I have now installed. There is still something seriously wrong with the display system however and I don't know if it's an xorg thing or something else. I don't think it's the new MGA driver because I get console problems even if I don't run X. If I run 'joe', the editor, from a standard console (No X) I find I cannot get out using Ctrl-C, it's just ignored, but I can exit with Ctrl-K-X. However I then have to type 'reset' to get the console to behave properly. Whilst in the editor I often can't scroll down to see the end of the file. I cannot start X as a user but I can as root. If I start X as root and then exit I have to do the 'reset' thing again. I can start KDM as root and then log in as a user but if I logout, back to KDM, I'm stuck because Ctrl-Alt-Fn doesn't work either. All I can do is reboot. Is this likely to be an xorg problem and where do I look to solve it? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Any Asterisk users out there? Dial out fails, but dial in works
by Ashley T. Howes, Ph.D. 13 May '06

13 May '06

I'm attempting to set a small PBX system. I'm using Asterisk @ Home 2.8 with a Digium TDM11B card. The fxo card is in port 4, the fxs card is in port 1. I have the phone-line connected to port 4 and the phone unit to port 1. My /etc/zaptel.conf is: fxoks=1 fxsks=4 loadzone=uk loadzone=uk My /etc/asterisk/zapata.conf includes: echocancel=yes echocancelwhenbridged=yes echotraining=400 callerid=<my callerid> signalling=fxo_ks group=1 context=default channel => 1 signalling=fxs_ks callerid=asreceived group=2 context=incoming channel => 4 My /etc/asterisk/extensions.conf is: [globals] OUTBOUNDTRUNK=Zap/4 [incoming] exten => s,1,Wait(1) exten => s,2,Answer() exten => s,3,Playback(hello-world) exten => s,4,Hangup() [outbound] exten => _9XXXXXXXXXXX,1,Dial($(OUTBOUNDTRUNK)/${EXTEN:1}) exten => _9XXXXXXXXXXX,2,Congestion() exten => _9XXXXXXXXXXX,102,Congestion() The _9XXXXXXXXXX should allow me to call number like 07770 123456 using a 9 prefix from the phone, if I understand the documentation correctly. Some of this information was from the supplier of the card and others were from Asterisk O'Reilly book. Incoming calls work as expected, but as soon as I attempt to use my phone to dial a number, it hangs up. I hear a dial-tone to begin with, but pressing a single button makes it hang up. The log from Asterisk is: --Starting simple switch on 'Zap/1-1' --Hungup 'Zap/1-1' What is wrong? This is really confusing. I'm a newbie to Asterisk so if there is something I have missed above, please point it out. -- Ashley T.
