Weekly IRC reminder
by Brett Parker 26 Jun '06

26 Jun '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!)

List weirdness
by Wayne Stallwood 25 Jun '06

25 Jun '06

Just got a bounce from the main list. But the subject it mentions I haven't sent an email with since the end of May and that message did show on the list...I did cause a bounce on the Amarok message because I accidentally sent it from the wrong account at 1.51PM..I got the bounce for that and resent it from the right account. But this bounce turned up at 5:06 PM today. Can one of the list admins tell me what happened ? Your mail to 'main' with the subject Bletchley Park Is being held until the list moderator can review it for approval. The reason it is being held: Message has a suspicious header Either the message will get posted to the list, or you will receive notification of the moderator's decision.

Laptops, desktops, and UPS
by Ted.Harding＠nessie.mcc.ac.uk 23 Jun '06

23 Jun '06

Hi Folks, I thought I'd push out for comment a thoguht which I've been pondering from time to time. A laptop is pretty nearly immune to mains supply failure, since its battery provides a backup and modern laptops can shutdown on low battery. Desktops, on the other hand, need an external UPS to guard it against mains failure; and of course a UPS can be configured to signal the computer to shut down if the power cut lasts more than a certain time. But it has occurred to me that there's no obvious reason why a desktop can't have its own internal battery like a laptop, and I'm wonderign why they don't. Of course, laptop batteries are notorious for not having a very long useful life -- you can be lucky, in some cases, if you get 5 years out of one. And they're even more notorious for being horrendously expensive to replace, if indeed you can still find one by the time yours fails. But I'd have thought that the space available in a desktop would offer scope for a more robust and cheaper solution. (In passing -- I have an ancient laptop whose battery has been shot for years, which however works well if you plug 12v DC into its PS socket; so I've happily been using it in "away from the mains" situations by attaching it to a motorcycle battery which weighs less than 4 pounds -- 1.7kgm -- so is within my definition of "portable"). So a robust lead-acid battery of the appropriate voltage could be installed into a desktop, if the appropriate circuitry were present in the box's PSU, and would presumably last longer, be easier to replace if necessary, and cost much less. Does anyone know of desktop boxes which do this? Thanks, and best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 23-Jun-06 Time: 15:18:44 ------------------------------ XFMail ------------------------------

Crazy question
by Peter 23 Jun '06

23 Jun '06

In a shop run by a friend, and he said his machine was behaving oddly. To his surprise, he had a 120G drive, but from the windows disk utility, there was only 30 in a partion, Drive C, and the rest as unallocated space. He did not know how this had happened or when, but was fairly sure it had not been bought set up like this. He is also getting notices on the screen that memory dumps are happening. He is firewalled and anti virused and updated. But he doesn't have specific anti spyware. Question: have you ever heard of anything like this happening as the result of an infection? Is it a reasonable investigative first step to boot from a live Linux CD and find out if it shows up as unallocated space in that too? And what would you then advise using to see if the space really is unallocated and with nothing in it? I have system rescue CD, and could get any of the other security oriented distros, but this isn't really my area.... Peter

How to check for packet loss over a long[ish] period?
by chrisisbd＠leary.csoft.net 22 Jun '06

22 Jun '06

I want to run some checks on my ADSL connection to see what sort of level (if any) of packet loss I am getting. In particular I want to run some checks in the small hours of the morning because I'm getting some rsync errors which might be due to packet loss. What tools are available for checking packet loss? Is there anything better than 'ping' and/or what is a civilised repeat rate to use with ping to avoid it being seen as a DoS attack? The system I'm rsync'ing with does respond to 'ping' so that's a start. -- Chris Green (chrisisbd(a)leary.csoft.net)

Strange hardware problem
by Wayne Stallwood 22 Jun '06

22 Jun '06

We have a server at a clients that has been showing random signs of instability (random reboots and a couple of panics) Suspecting hardware problems I brought it down and ran memtest86 on it. Then something odd happened. Memtest shows plenty of memory errors, spreading over pretty much the whole of the installed 512MB. When I stopped the tests halfway through the first pass there were two pages, the lowest error was at about 50MB the highest was at circa 430 But the really strange thing is that the error bits are 00000000 i.e the test data and "bad" data match perfectly. There is no ECC on this machine so how can the data I put in the memory and the data I take out be the same yet there be a memory error. Memtest clearly shows the "good" and "bad" column with matching data but still flags these as errors. I have ordered replacement RAM anyway, but I was just interested in what other type of memory error I am seeing here ?

Wierd DNS problem
by chrisisbd＠leary.csoft.net 20 Jun '06

20 Jun '06

We have a wierd DNS problem at work, it's almost certainly something to do with low level DNS setup and/or the firewall but we're a bit lost as to where to look. >From our Solaris boxes issuing an 'nslookup xxx.yyy.zzz' gives the correct IP address for the domain xxx.yyy.zzz. However every application lookup of domain name xxx.yyy.zzz gives the wrong result. The wron result is always that of a domain at Network Solutions, a US name registration business. DNS works OK from PCs on the network. So it looks like something adrift on our name lookup machine but we really cannot see what at the moment. When an application asks for a name resolution what is the normal order of things happening? -- Chris Green (chrisisbd(a)leary.csoft.net)

Disk usage
by Wayne Stallwood 19 Jun '06

19 Jun '06

I think this question may have come up on the list before, but I can't find an answer in the archives. /dev/sda3 111G 102G 3.1G 98% /home Why is my free space only shown as 3.1G if I have used 102G out of 111 ? BTW Windows Vista is a disk space hog, a clean installation into a virtual machine took 8GB (minus 840MB for virtual memory) That's before you add any apps (and office 12 is Huge)
